Ambiences that represent environments or landscapes play a crucial role in the soundtrack of a film when the geographic setting is important for the film’s narrative. When sound designers can encourage viewers to both notice and accept the environment displayed in the film, this can contribute to an immersive experience. Prior research has discussed how changes in the level of detail, or complexity, of ambiences and soundscapes can affect the perceived immersion of a film experience. This study aims to further investigate this topic by looking at how the complexity of a minor category of sound elements, environmental sounds, affects the immersiveness of a film scene. A listening/viewing test was conducted in a controlled studio environment where participants watched a video segment that was synced to two different versions of an environmental soundscape. One version was more complex than the other. All of the subjects watched and listened to the same video-soundscape combinations. Both quantitative and qualitative data were collected through an online questionnaire. The participants were asked to rate the video segments for immersion-related qualities and to motivate their ratings. The results did not show enough statistical significance to support the idea that a change in complexity affects all of the three qualities perceived presence, realism and how accurately the amount of sonic details matched the picture. However, the subjects’ motivations of their ratings for perceived presence and realism indicate that a detailed, layered soundscape that includes rarely occurring sound elements provides a stronger experience of presence and realism. Future research based on the findings from this study is presented.

When striving for realism in first-person games, the use of sampled audio has been frequent, and it is often argued that a higher level of auditory authenticity will lead to an increased realism.However, in this paper, it is argued that, for the purpose of realism, attention should instead be directed at making players themselves a more contributing factor to how sound is perceived; the more the audio of a game changes with, or adapts to, player input, the more realistic it should be perceived. This idea is tested in a first-person game where participants play two different levels where one level’s wind sound has audio parameters adapt to the camera’s yaw rotator value, while the other level’s wind sound does not adapt at all. The participants’ experience of each design approach is evaluated using a quantitative and qualitative analysis. Results suggests that an increase of adaptive audio can lead to an increase in perceived realism in first-person games. A difference could clearly be perceived between the approaches and there were indications of preference for the adaptive approach. First-person games, such as simulators, as well as VR games, may well benefit from this approach in that it could increase the perceived realism.

Tillsammans med bland annat digitaliseringen av musik och den illegala fildelningen är musikstreaming en av de största förändringarna som vi har varit med om i musikbranschen. I takt med att musikstreamingen har växt och blivit mer populär har det även inneburit att artister inte längre behöver skriva skivkontrakt med skivbolag om de inte vill. Artister har nu istället möjligheten att själva lägga upp sin musik på diverse musikstreamingtjänster vilket har resulterat i att musikbranschen är fylld utav personer som vill bli etablerade på musikmarknaden till den grad att de kan försörja sig på musiken. Eftersom möjligheterna till att synas i traditionell marknadsföring i form av exempelvis tidskrifter och intervjuer oftast är reserverat för de artister som har ekonomisk backning av skivbolag använder sig istället artister utan skivkontrakt utav sociala medier i hopp om att sticka ut i mängden och på så sätt sprida sin musik. Utöver spridningen på sociala medier har även den traditionella ljudproduktionen, med producenter och kompositörer samt låtskrivare, förändrats så att en enda person nu kan inneha alla dessa roller när de ska släppa sin musik vilket har skapat fler möjligheter för musiker att tjäna pengar på sin musik.

Nivådesign är en viktig del inom spelutveckling för att skapa fängslande och inlevelserika digitala världar. Hur spel- och nivådesigners kan skapa en intuitiv interaktion mellan spelare och spelnivå med hjälp av olika typer av vägledning, utan att det blir för lätt eller svårt, är en fråga som vi saknar svar på. Vår studie undersöker hur vägledning kan stimulera inlärning- och problemlösning för att uppnå flow. Vi undersöker även vad det har för påverkan på uppmärksamhet samt vilka personliga preferenser spelare av vägledning. För att få svar på dessa frågor utfördes en kvalitativ undersökning där 8st deltagare fick spela Mirror’s Edge Catalyst med eller utan spelets inbyggda vägledningsfunktion ”Runners Vision”. Vi kom fram till att vägledning är väldigt användbart för både nybörjare och målfokuserade spelare. För att vägledningen ska vara effektiv så är det viktigt att spelet skapar en tydlig association mellan handling och problem för spelaren vilket kräver en form av positiv eller negativ respons. Det finns även vissa konsekvenser av vägledning såsom att spelet blir för enkelt eller tar ifrån spelarens självständighet. Dessa utmaningar kan förslagsvis lösas genom att använda adaptiva vägledningsfunktioner som baseras på spelarens individuella behov och förmågor.

Background. Head-tracking enables the use of head movements as a form of input for video games. Some games allow the player to use their head to orient the in-game camera. However, the movement of the in-game camera is seldom proportional to the movement of the player. Head-Coupled Perspective is achieved by tracking the player’s head and displacing the in-game camera similarly. There is a lack of data gathered on how a Head-Coupled Perspective affects user experience in video games. Objectives. The aim of this thesis is to investigate how Head-Coupled Perspective affects user experience by implementing it into a first-person shooter game. Methods. Head-Coupled Perspective was implemented into Receiver 2 (WolfireGames LLC). An experiment was conducted where 28 participants were divided into two groups. The groups were divided by the order in which they play the standard version and the Head-Coupled Perspective version of the game. Their impressions were measured using a questionnaire adapted from the Game Experience Questionnaire. After playing both versions, participants answered comparative questions comparing the game versions. Participants’ in-game task completion time and head velocity were recorded during the tests. Results. The results showed that both groups preferred the first version of the game they played. Overall, the Head-Coupled Perspective version of the game generated higher scores for the Flow and Negativity constructs. The results gathered through the questionnaire had low statistical significance. Conclusions. This study indicates that task engagement and negative feelings increase when playing a First-Person Shooter game with Head-Coupled Perspective. However, due to the low statistical significance of the data, more work is required on the subject before a rigorous conclusion can be drawn. On top of that, Head-Coupled Perspective had no significant effect on the difficulty of the game and the subjects' head velocity., Bakgrund. Huvudspårning möjliggör användning av huvudrörelser som en form av inmatning för datorspel. Vissa spel låter spelaren använda huvudet för att orientera kameran i spelet. Mängden rörelse för kameran i spelet är dock sällan proportionell mot spelarens huvudrörelse. Huvudbundet perspektiv uppnås genom att spåra spelarens huvud och röra spelets kamera därefter. Studier har utförts om hur ett huvudbundet perspektiv påverkar användarupplevelsen i datorspel. Men för lite data har genererats från dessa tidigare studier för att dra en slutsats om dess påverkan på användarupplevelsen. Syfte. Syftet med denna rapport är att undersöka hur huvudbundet perspektiv påverkar användarupplevelsen genom att utveckla det för ett förstapersonsskjutspel. Metod. Huvudbundet perspektiv implementerades i Receiver 2 (Wolfire GamesLLC). Ett experiment genomfördes där 28 deltagare delades in i två grupper. Grupperna är uppdelade efter den ordning i vilken de spelar standardversionen och den huvudbundna perspektivversionen av spelet. Deras intryck mättes med hjälp av frågeformulär anpassat från Game Experience Questionnaire. Efter att ha spelat och svarat på enkäten för båda versionerna svarade deltagarna på frågor som jämförde spelversionerna. Tiden deltagarna tog för att fullfölja speluppgiften mättes. Samt spelarnas huvudrörelser mättes under testerna. Resultat. Resultaten visade att båda grupperna föredrog den första versionen avspelet de spelade. Totalt sett genererade den huvudbundna perspektivversionen avspelet högre poäng för Game Experience Questionnaire områdena associerade medspelengagemang och negativitet. Resultaten hade låg statistisk signifikans. Slutsatser. Den här studien indikerar att spelengagemang och negativa känslor ökar när man spelar ett förstapersonsskjutspel med huvudbundet perspektiv. På grund av den låga statistiska signifikansen hos datan krävs mer arbete inom ämnet innan en rigorös slutsats kan dras. Utöver det har huvudbundet perspektiv ingen signifikantp

Background: The usage of video games for educational purposes has become more prevalent in the recent decade. There are a lot of studies showing that video games can affect a person’s cognitive abilities. However, few studies have aspired to determine if a virtual environment can affect a person’s Game experience. A few examples are competence, negative effects and positive. In this research, an experiment will be conducted where participants are asked to solve simple puzzles in four different virtual environments. Afterwards, the participants are asked to answer a questionnaire based on the Game Experience questionnaire. The results will be compiled, analyzed and discussed. Objectives: The objective of this research is to assess if the different virtual environments affect the subjects’ experience positively and negatively.Methods: The main research methods in this project will be implementation and experimentation with a questionnaire. Where the participants will be given different virtual environments to walk around in and solve simple puzzles. The data will then be analyzed. Results: Some of the results were expected and confirmed some of our hypotheses, however, the other half of the results were unexpected.Conclusions and future work: Different virtual environments had a major impact on a player’s game experience. Environments that are considered "negative" would affect the player’s experience negatively. And "positive environments would affect the player’s experience positively. However, it varies greatly from person to person. For future work, an increase in participants and more carefully planned environments may yield a more accurate result.

I den här uppsatsen undersöks hur ljud och musik kan användas som verktyg för avslappning, utifrån frågeställningen: Hur skapas ett musikstycke som gör lyssnaren avslappnad? Litteraturstudier som behandlar den mänskliga faktorn i hur musik påverkar oss, såsom musikhantering i hjärnan, neurologi, hjärnans utveckling i de tidiga stadierna och psykologi låg till grund vid komponerandet av ett musikstycke som sedan testades i en enkät. Resultaten visade på att en majoritet tyckte att musikstycket var behagligt och avslappnande, men samtidigt fanns en stark kontrast där en stor del av försökspersonerna upplevde det som helt tvärtemot- stressande och obehaglig. Några tyckte att stycket var sorgligt, och två tyckte att det var komiskt. Nio personer svarade att de skulle lyssna på stycket för att koncentrera sig, en tyckte att musiken skapade ett koncentrerat tillstånd

Detta projekt genomfördes med syftet att undersöka hur den moderna teknologin i musikbranschen påverkar musikskaparnas musikaliska kunskapsnivå och därigenom deras musikskapande. I fokus låg musikteori kopplat till takt och rytm, något som är väsentligt för i princip alla olika musikstilar. För att undersöka området gjordes en enkätundersökning samt en intervju. Enkätens syfte var att ge en bredare bild av problem som musikskapare ofta stöter på och till viss del vad dessa kan bero på. Intervjun gjordes med en van musikskapare som har goda musikteoretiska kunskaper och handlade om hur denne upplever att de kunskaperna påverkar hans kreativa arbete. Även personens upplevelser av rytm-programmering diskuterades. Ämnet i fråga visade sig bygga på individuella behov och lösningar i och med att problemen är av samma karaktär. Ju fler hjälpmedel som finns och ju fler vägar som kan vandras, desto starkare kan branschen växa sig.

Digitala inslag har idag en stor roll i skolan, men inom matematik klamrar lärare sig fast vid traditionella undervisningsmetoder. Samtidigt tryter motivationen för matematik hos mellanstadieelever. För att öka motivationen inom matematik uppmanas lärare att utgå från elevernas intresse. Undersökningar visar att en stor majoritet av barn i åldrarna 9–12 år spelar digitala spel dagligen. Det finns därmed ett intresse hos eleverna som matematikämnet kan ta vara på. Syftet med denna litteraturstudie är att granska vad forskningen säger kring digitala lärspels påverkan på mellanstadieelevers motivation och lärande inom matematik. Detta för att synliggöra om digitala lärspel har förutsättningar att vara en central del i matematikundervisningen i årskurs 4–6. För att undersöka vad forskning säger inom området genomfördes en litteraturöversikt där sökningarna genererade elva vetenskapliga artiklar. Utifrån dessa artiklar genomfördes en tematisk analys som synliggör att majoriteten av de granskade artiklarna visar att digitala lärspel har en positiv påverkan på elevernas lärande, medan en knapp majoritet visar positivt för elevernas motivation. I vilken utsträckning det digitala lärspelet påverkar elevernas lärande och motivation beror på en rad olika faktorer och samspelet mellan dessa.

Music listening is considered one of the most ubiquitous activities in everyday life, and one of the main reasons why people listen is to affect and regulate their mood. The vast availability and unlimited access of music has made it difficult to find relevant music that fits both the context and the preferences of the music listener. The aim of this project was to investigate the personalized relationship between music and mood using everyday technologies, focusing on how a listening experience could be adapted to the desired affect of a music listener while also taking the user’s individual listening history into account. In large, the project concentrated on the possibility of using context-aware music recommendation to generate personalized playlists by focusing on the audio features and corresponding mood of the music. A web-based application was developed to act as a prototype for the study, where the application allowed users to connect to Spotify, pick a desired mood and generate a playlist. By allowing people to access music in this personalized way, a user study could be conducted in order to investigate their music listening while incorporating this recommendation tool. The findings showed that the users’ found the experience to be engaging in that they could use the application as a companion to everyday tasks in addition to it being a tool for getting new, personalized music recommendations. Overall, the participants also found the generated playlists to be accurate to their music preferences and desired affective state.

Att skapa en berättelse inom illustration, som till exempel i serier, går oftast ut på att en bild följs av en annan för att berättelsen ska vara förståelig och tydlig. Blandar man ihop bilderna blir serien utan en röd tråd och berättelsen tappar sitt narrativ men storytelling är mer än att endast para ihop bilder i en följd så som det ska vara. I denna undersökning utforskar vi hur man kan skapa en serie illustrationer som skapar ett narrativ oavsett hur de sätts ihop. Vi har utforskat surrealistiska konstmetoder som automatism, cut-up, association, och bildgenerering då våra illustrationer har inslag av surrealism. Därefter har vi använt oss av användartester för att få en uppfattning om hur effektiva våra illustrationer är i att skapa flera narrativ genom illustrationernas ordning. Vi har dragit kopplingar till film, comics, och illustrationer samt går vi in på djupet gällande hur saker som färg, form, komposition, miljö och hur dessa faktorer påverkar ett narrativ. Våra illustrationer fokuserar på visuell kommunikation utan hjälpmedel som text, ljud, eller rörelse (animation). Resultatet pekade på att det mesta beror på individen, ens egna erfarenheter och bakgrund, för att hitta ett narrativ i en mängd illustrationer som är öppna för tolkning., Creating a story with illustrations such as comics is usually made through a set sequense of pictures in an order that makes the story comprehensive. If you move the pictures around the story loses its narrative however storytelling is more than putting pictures in a sequence. This paper is made with the purpose of exploring how we can create a series of illustrations with a comprehensive narrative no matter what order you put them in. Since our illustrations are inspired by the artform of surrealism we have explored surrealistic methods such as automatism, cut-up, association, and generating of pictures. We later used user testing to test the effectivness of our illustrations and their capability to create multiple narratives based on the order of the illustrations. We have made connections to things such as movies, comics, and illustration and take a deep dive into factors like colour, shape, composition, background and how they affect the narrative. Our illustrations focus on visual communication and will therefore not include text, sound, or movement (animation). The result showed that it depends on the individual, a person's own experiences and background, to find a narrative in a set of illustrations that are open for interpretation.

Denna undersökning belyser varför beröring är ett viktigt sinne för att stärka VR-upplevelser. Genom att använda beröring som metod för att utforska fysiska egenskaper har vi skapat endigital gestaltning som demonstrerar hur denna unika förmåga kan användas. Denna undersökning har bidragit till skapandet av ett nytt verktyg för framtida utveckling av VR-upplevelser, vilket har öppnat upp möjligheter att använda beröring som huvudmekanik. Genom att kombinera haptisk feedback och visualisering av händer och omgivning kan vi utforska och interagera med VR-spel på ett nytt och spännande sätt., This study highlights why the sense of touch is important for enhancing VR experiences. By using touch as a method to explore physical properties, we have created a digital representation that demonstrates how this unique ability can be utilized. This study has contributed to the development of a new developer tool for future VR experience design, which has opened up possibilities for incorporating the sense of touch as a main mechanic. By combining haptic feedback and visualization of hands and the environment, we can explore and interact with VR games in a new and exciting way.

TikTok har blivit en populär plattform under de senaste åren, särskilt bland unga kvinnor. Tidigare forskning har visat att med användningen av sociala medier, särskilt visuella plattformar som TikTok, kan påverka mental hälsa hos kvinnor. TikToks algoritm översvämmar användare med riktat innehåll som fokuserar på utmaningar och trender relaterade till utseendeförändringar genom kosten, träning och försköningsfilter. För unga kvinnor kan detta leda till ökad oro över kroppen och försämrad mental hälsa. Denna studie syftar till att undersöka innehållet som publiceras på TikTok och dess potentiella inverkan på mental hälsa. En kvantitativ enkätundersökning genomfördes för att undersöka unga kvinnor i åldrarna 15-25 år och deras attityder till TikTok och kroppsideal. Genom en kvalitativ tematisk videoanalys av hashtaggen #bodypositivity identifierades strukturer för hur kroppspositivitet framställs på plattformen. Studien har funnit både negativa och positiva effekter av applikationen och vilket innehåll användarna exponeras för i relation till kroppspositivitet. Det framkom att hashtaggen #bodypositivity ibland kan missbrukas. Användarna har en viss grad av kontroll över vilket innehåll de konsumerar, vilket påverkar deras upplevelse och känsla av plattformen. Trots medvetenheten om detta har användare emellertid ibland svårt att distansera sig från negativa påverkningar och fortsätter att exponera sig för innehåll som påverkar dem negativt., TikTok has become a popular platform in recent years, especially among young women. Previous research has shown that the use of social media, especially visual platforms such as TikTok, can affect the mental health of women. TikTok's algorithm floods users with targeted content that focuses on challenges and trends related to appearance changes through diet, exercise and beautification filters. For young women, this can lead to increased anxiety about the body and deteriorating mental health. This study aims to examine the content posted on TikTok and its potential impact on mental health. A quantitative survey was conducted to investigate young women aged 15-25 and their attitudes towards TikTok and body ideals. Through a qualitative thematic video analysis of the hashtag #bodypositivity, structures were identified for how body positivity is presented on the platform. The study has found both negative and positive effects of the application and the content the users are exposed to in relation to body positivity. It emerged that the hashtag #bodypositivity can sometimes be misused. Users have a certain degree of control over what content they consume, which affects their experience and feel of the platform. However, despite awareness of this, users sometimes find it difficult to distance themselves from negative influences and continue to expose themselves to content that affects them negatively.

The objective of this thesis is to explore technologies and solutions and see if it is possible to make a logistical flow more efficient. The logistical flow consists of a database containing materiel for purchase or reparation. As of now, searches may either result in too many results, of which several are irrelevant, or no results at all. The search needs to be very specific to retrieve the exact item, which requires extensive knowledge about the database and its contents. Areas that will be explored include Natural Language Processing and Machine Learning techniques. To solve this, a literature study will be conducted to gain insights into existing work and possible solutions. Exploratory Data Analysis will be used to understand the patterns and limitations of the data.

This thesis is written within the topic of Internet of Things (IoT) and smart homes among young adults in Sweden. Smart homes are taking up more and more space on the housing market and aim to make consumers' everyday lives easier. Factors behind buying a smart home present a gap of knowledge about who the potential buyers are among young adults. The essay is written with the aim of reviewing generation Y and Z’s ownership and regular use of smart home devices in their households in terms of usefulness and ease of use. The aim is also to gain an insight into the willingness of generation Y and Z to buy and pay for a smart home. By using previous research combined with a quantitative study in the form of a web survey, an analysis was formed from the consumers' responses. The result shows that young consumers have a broad knowledge of what IoT means with a majority having at least one smart device in their household. The willingness to buy and pay for smart homes is proving to be varied, with young consumers not yet convinced on the issue. The outcome of the thesis contributes to an interesting discussion about IoT and smart homes from different perspectives and gives you as a reader knowledge about smart home devices and their potential in the housing market.

Through interviews with copywriters, this essay examines how AI technologies may influence the creative process their work. We must also look at whether AI can be creative in order to provide an answer to the study topic. Therefor the paper explores the concept of creativity.The conclusion according to the study, shows that AI can be creative when collaborating with humans. For a copywriter, using AI streamlines and simplifies their process. The study also demonstrates that co-creativity, or human and AI collaboration in the creative process, is advantageous to both copywriters and AI.Furthermore, the study demonstrates that copywriters are not necessarily threatened by AI. Certain simple aspects of the process, such swiftly collecting and compiling data, can be replaced by AI systems. A collaboration primarily shows beneficial consequences for a copywriter. They have more time for creativity in their job process. Although most of the study's interviewees are supportive of a wider use of AI technologies in the media sector, there are concerns regarding AI's limited capacity for critical engagement with its own creations. It is also argued that AI lacks other crucial characteristics like warmth and soul, which are essentials aspects of creativity.

A study has been implemented regarding the acoustical characteristics of a black box and its influence on rock and metal music live performance. Objective acoustical measurements have been made as well as a subjective evaluation in form of a listening test. The results have shown uneven distribution in the frequency domain in addition to exaggeration in the low frequency domain which affects the sound quality regarding rock and metal live productions. It is suggested in general to apply acoustic treatments in form of adjustable acoustic ceiling and diffusers on walls to achieve even frequency distribution. It is also suggested to have specific configurations regarding the sound reinforcement system as well as a proper tuning of the sound to obtain better integration with the acoustics of the hall.

This paper analyzes the current possible implementations and limitations of generative AI applications such as Chat-GPT, DALL-E, and Midjourney. The applications were used in a specific scenario to gauge whether it was able to effectively handle a potential request from a client, the scenario was to create a visual identity for a shoe company called WalkWise. The creations are then analyzed using Gestalt theories of perception and the machine-learning mechanisms that run these applications. To understand just how graphic designers may introduce these tools into their process, a process chart describing a typical graphic design process for a project has been created using data gathered from 8 professionals in the field who were interviewed. Using a thematic analysis, common occurring themes/activities were found and visualized in a process chart. The process was later analyzed using theories in process value analysis. Using all this information a conclusion was made that AI-generated art has several limitations that inhibit it from completely replacing human designers. These included: not understanding/generating vector graphics, not understanding objects in 3D space from less natural angles, often generating visual clichés, some potential copyright issues, and not being able to generate words. The implementation was therefore limited to a visual brainstorming tool which could aid graphic designers in quickly visualizing an idea or visualizing several different versions of one idea without having to sketch these differences, thereby making the idea-generating parts of the process more efficient.

Sonification allows for the analysis and interpretation of data through its rendering into sound. It is a method that remains largely unexplored from a digital humanities perspective. The present thesis addresses this research gap by exploring aspects of sonification as a mode of data perceptualization. Methodologically, it combines an extensive review of sonification literature with the design of a sonification prototype. The prototype is created using an exploratory programming approach and is evaluated through a small user study. One of the main challenges of using sonification within the humanities consists in aligning it with humanistic interpretative and critical modes of inquiry, in the thesis understood through the framework of Johanna Drucker’s critical hermeneutics. Another challenge is related to the shortage of existing projects and previous research, and also to a lack of relatively easy-to-use sonification tools. In the thesis, these challenges are primarily made visible through the process of prototype design and through the subsequent user study. Nevertheless, the literature review successfully uncovers a number of potential strategies for the realization of humanistic-interpretative sonification design, focusing especially on the concepts of phenomenology of listening and musical sonification. By applying musical sonification, it becomes possible to move beyond the simple representation of data, allowing instead for interpretative approaches. The findings presented in the thesis provide foundations for future research into humanities sonification.

Digital platforms have deeply transformed a wide variety of sectors. However, new platform business models often face critical legitimacy challenges. Consequently, new entrants must continuously design and redesign their business model components, particularly when entering non-platformized sectors that are highly regulated. We draw on a longitudinal case study of the emergence of digital healthcare platforms in Sweden between 2013 and 2020. The analysis unravels a dynamic process of redesigning platform business models and their constituent components in response to legitimacy debates, suggesting that permission to operate can be fragile and subject to continuous negotiation. Our findings contribute to current insights into platforms, business models, and digital innovation in complex institutional contexts. Furthermore, our work carries implications for managers and policy makers in the digital health area., Validerad;2023;Nivå 2;2023-04-20 (joosat);Licens fulltext: CC BY License

The appearance of an object is determined by its chromatic and geometric qualities in its surrounding environment using four optical parameters: color, gloss, translucency, and surface texture. Reconstructing the appearance of objects is of great importance in many applications, including creative industries, packaging, fine-art reproduction, medical simulation, and prosthesis-making. Printers are reproduction devices capable of replicating objects’ appearance in 2D and 3D forms. With the introduction of new printing technologies, new inks and materials, and demands for innovative applications, creating accurate reproduction of the desired visual appearance has become challenging. Thus, the appearance reproduction workflow requires improvements and adaptations. Accurate color reproduction is a critical quality measure in reproducing the desired appearance in any printing process. However, printers are devices with a limited number of inks that can either print a dot or leave it blank at a specific position on a substrate; hence, to reproduce different colors, optimal placement of the available inks is needed. Halftoning is a technique that deals with this challenge by generating a spatial distribution of the available inks that creates an illusion of the target color when viewed from a sufficiently large distance. Halftoning is a fundamental part of the color reproduction task in any full-color printing pipeline, and it is an effective technique to increase the potential of printing realistic and complex appearances. Although halftoning has been used in 2D printing for many decades, it still requires improvements in reproducing fine details and structures of images. Moreover, the emergence of new technologies in 3D printing introduces a higher degree of freedom and more parameters to the field of appearance reproduction. Therefore, there is a critical need for extensive studies to revisit existing halftoning algorithms and develop novel approaches to produce high q, 2023-10-09: The cover was updated to reflect the printed version.

We discuss the design and results of The Ai Music Generation Challenge 2022 and compare it to the previous two challenges. While the 2020 challenge focused on generating Irish double jigs, and the 2021 challenge focused on generating Swedish slängpolskor, the 2022 challenge posed three sub-challenges in the context of Irish traditional music: generation of reels, judging tune submissions, and titling tunes. In total seven systems participated in the sub-challenges, along with benchmark systems. One tune was awarded first prize by the judges, and two tunes shared second prize. A submitted system for judging tunes clearly performed better than two benchmarks. Finally, human tune-titling outperformed the benchmark and submitted system, but gave rise to some interesting issues about tune titling., QC 20230911

Even if images of astrophysical objects are used by professional astronomers for research and by the public for outreach, we are all basically blind to the Universe. Challenging the idea that we should always use visualisations, there has been a growing interest in converting astronomical phenomena into sound, motivated by: making astronomy more accessible to people who are blind or visually impaired (BVI); creating more engaging educational resources, and enabling a deeper understanding of complex astronomical data. The Audible Universe (AU) workshop focuses on consolidating what has been done in the field so far and identifying the areas where most effort is required to make progress over the coming years. The second edition of the AU workshop (AU2) took place in 2022, and brought together 50 experts, among whom astronomers interested in sonification, sound designers, experts in sound perception and educators. This community started a multi-disciplinary discussion about how to properly design and evaluate sonification tools. In this methodological and position paper, we present and discuss the main activities of the AU2 workshop, with a particular focus on activities concerned with the development of collaborative design processes, and the implementation of methods for evaluation. While this workshop was dedicated to fostering exchanges between the sonification community and astronomers, the structure and the methods used within the workshop are transferable to other application areas, and a contribution to the effort to develop interdisciplinary strategies for the development of the field of sonification., QC 20230705

This paper presents an experimental design of a dual-task experiment aimed at exploring the salience of auditory notifications. The first task is a Sustained Attention to Response Task (SART) and the second task involves listening to a complex store soundscape that includes ambient sounds, background music and auditory notifications. In this task, subjects are asked to press a button when an auditory notification is detected. The proposed method is based on a triangulation approach in which quantitative variables are combined with perceptual ratings and free-text question replies to obtain a holistic picture of how the sound environment is perceived. Results from this study can be used to inform the design of systems presenting music and peripheral auditory notifications in a retail environment., QC 20230705, Sonification of Goods in Stores, Sweet-sounding Shop Goods

In this paper we describe the development of two heat and movement-sensitive sonic textile prototypes. The prototypes interactively sonify in real-time the bodily temperature of the person who wears them, complementing the user’s felt experience of warmth. The main aim is making users aware of the heat exchanges between the body, the fabric, and the surrounding environment through nonintrusive and creative sonic interactions. After describing the design challenges and the technical development of the prototypes - in terms of textile fabrication, electronics and sound components - we discuss the results of two user experiments. In the first experiment, two different sonification approaches were evaluated allowing us to select the most appropriate for the task. The prototypes’ use-experience was explored in the second experiment., QC 20230614

Changes in the footballing world's approach to technology and innovation, along with major advancements in broadcasting contributed to the decision by the International Football Association Board to introduce Video Assistant Referees in 2018. The change meant that under strict protocols referees could use video replays to review decisions in the event of a "clear and obvious error" or a "serious missed incident". At the time of writing 48-Member Associations have introduced the Video Assistant Referees protocol in at least one of their tournaments and there are many technology providers who work with organisers to implement the Video Assistant Referees systems. To ensure that the use of Video Assistant Referees has a positive effect on the game, Federation Internationale de Football Association collaborated with the RISE Research Institutes of Sweden to develop objective test methods that could be used to ensure that a system can provide an adequate solution. Each provider must be able to pass requirements that ensure that they can deal with the challenges of processing, coding, decoding, synchronising, and re-formatting of the broadcast feeds. This article will describe the development of the test methods and illustrate some initial results from a test event on Video Assistant Referees system candidates. The methods have shown to be robust and appropriate for their intended purpose and will be developed over the years to ensure the quality of Video Assistant Referees.

Procedurell generering är ofta använt av spelutvecklare i dagens moderna samhälle. Generellt så används procedurell generering mestadels till att generera terräng och texturer, vilket är ett välutforskat område, men det är bara början till vad det kan användas till. Därför är den här artikeln istället fokuserad på användandet av procedurell generering för att generera förmågor som kan användas till ett spel i MOBA genren, i ett försök att sprida kunskap och utveckla andra användningsområden för procedurell generering. För att utforska den möjliga metodiken till användandet av procedurell generering för att generera förmågor så dokumenterar artikeln först redan existerande metoder, sedan föreslås en ny metod för att göra upp för bristerna i den existerande metoden och slutligen så implementeras den nya metoden i en spelprototyp för att undersöka dess funktionalitet. För att validera resultaten av den nya metoden för procedurell generering av förmågor så jämförs den direkt med de redan existerande metoderna för att klargöra vad för- och nackdelarna är med den nya metoden. Resultatet av undersökningen visar att den nya metoden är långt ifrån felfri, men den är duglig nog för att vara ett alternativ till de existerande metoderna. I slutet av artikeln så tas möjligheten av att kombinera den nya och den existerande metoden för procedurell generering av förmågor upp i syfte att göra upp för varandras brister., Procedural generation is commonly used by game developers in today's modern world. Generally procedural generation gets mostly used for generating terrain and textures, which is a well explored area, but that is merely scratching the surface of possible use cases. This article therefore instead focuses on the usage of procedural generation to generate abilities to be used in a MOBA game, in an attempt to spread knowledge and develop other use cases for procedural generation. To explore possible methodologies of using procedural generation to generate abilities this article first documents already existing methods, then proposes a new method to make up for the shortcomings in the already existing methods and finally implements the new method in a game prototype to test its viability. To validate the results of the new method for procedural generation of abilities implemented in the game prototype it is directly compared to the already existing methods to ascertain what the pros and cons are of using the new method. The results of the research show that the new method for procedural generation of abilities is not the end all solution, but it is a viable alternative to the already existing methods. To tie things up this article brings up the possibility of combining both the existing methods for procedural generation of abilities and the newly designed one in the future in an attempt to mitigate the methods shortcomings.

I takt med teknologins utveckling växer även klyftan mellan visuellt innehåll och synskadade användare, då visualitet är den primära källan för informationsdesign. Denna artikel har som ändamål att undersöka hur en designer kan anpassa sin design och designprocess för att öka inkluderingen och minska kunskapsluckan. Artikelns litteratursamling berör ämnen som visual search, färgblindhet i samband med kontraster och andra indikatorer, formgivning och dess principer, detta skapade en bred grund för undersökningen och dess ändamål. Utöver informationssamling genomfördes intervjuer med Synskadades Riksförbund samt Unga med Synnedsättning Syd, för att skapa förståelse kring synnedsatta och deras behov. Resultaten baserades på relevant litteratur, information från metoder som intervjuer och användbarhetstest och ackumulerades i en tillgänglighetsmall gestaltad i en grafisk profil och webbplats för ett mock-up företag., As technology advances, the gap between visual content and visually impaired users also grows, as visuality is the primary source of information design. This article aims to explore how a designer can adapt their design and design process to increase inclusivity and reduce the knowledge gap. The literature review of this article covers topics such as visual search, color blindness in relation to contrasts and other indicators, design and its principles, which created a broad foundation for the investigation and its purpose. In addition to information gathering, interviews were conducted with the Synskadades Riksförbund and Unga med Synnedsättning Syd, to gain an understanding of the visually impaired and their needs. The results were based on relevant literature, information from methods such as interviews and usability tests, and were accumulated in an accessibility template designed in a graphic identity and website for a mock-up company.

Communication is a field of research that has been a core part of UX design for a while. In scientific literature communication is described as being a combination of several different psychic and physical events. Communication fulfills a number of pedagogical functions in humans. The communication in multiplayer games works in a different way than reality. The social world of multiplayer is very complex and there are many different ways for players to engage in interpersonal communication. All players of these games have unique personal attributes and belong to a unique typology. Player typologies are a young concept which has been defined by different psychometric models. One of those models is BrainHex which includes seven archetypes that typify a specific gaming experience. The model is still hypothetical and has much room to develop further. Until now there was a lack of reports on how these player typologies in the BrainHex model communicate with each other, as well as which ways of communication they prefer. The purpose of this study was to fill this knowledge gap and contribute to the field about communication in videogames. To collect data, scientific literature was reviewed and a digital survey was sent out. This was supplemented with anin-depth interview with a participant that was regarded as an expert on videogame development. The result of the study indicated there is no clear connection between player typologies and choice of communication method, but it was discovered that certain ways of communication were more favored. Choice of communication method is therefore not a staunch way to categorize player typologies in BrainHex., Det finns övrigt digitalt material (t.ex. film-, bild- eller ljudfiler) eller modeller/artefakter tillhörande examensarbetet som ska skickas till arkivet.There are other digital material (eg film, image or audio files) or models/artifacts that belongs to the thesis and need to be archived.

Artificiell intelligens (AI) har blivit alltmer betydelsefull i dagens samhälle, med växande tillämpningar inom olika kreativa områden. Denna kandidatuppsats syftar till att undersöka de potentiella fördelarna och riskerna som AI erbjuder för kreativa yrken inom media. Genom analys av åtta intervjuer studerar arbetet hur AI-verktyg, såsom ChatGPT, DALL·E och Midjourney, kan effektivisera arbetsprocesser, öka tidsåtgången för kreativt arbete och främja inspiration, samtidigt som det granskar de förknippade utmaningarna, såsom rättigheter, stereotyper, deepfake och påverkan på arbetsmöjligheter. Resultaten visar att användningen av AI medför både för- och nackdelar för kreativt arbete och antyder att denna trend kommer att fortsätta i framtiden. Även om potentialen för AI-teknik är stor, förväntas mänsklig kreativitet fortfarande att ha en avgörande roll i det kreativa arbetet. Avhandlingen avslutas med att betona samhällets och individernas ansvar att aktivt delta i utvecklingsprocessen och säkerställa att lämpliga lagar och regler finns på plats för att förhindra missbruk av olika AI-system inom den kreativa sektorn., Artificial intelligence (AI) has become increasingly significant today with growing applications in various creative fields. This bachelor thesis aims to explore the potential benefits and risks AI offers to creative professions within media. Through the analysis of eight interviews, the study investigates how AI tools, such as ChatGPT, DALL·E, and Midjourney, can streamline work processes, enhance creative work, and foster inspiration while also examining the associated challenges, such as rights, stereotypes, deepfakes, and the impact on work opportunities. The findings demonstrate that AI usage presents both advantages and disadvantages for creative work and suggests that this trend will continue in the future. While the potential of AI technology is vast, the industry is expected to undergo significant transformations. The thesis concludes by emphasizing the responsibility of society and individuals to actively participate in the development process, ensuring that appropriate laws and regulations are in place to prevent the misuse of various AI systems in the creative sector.

Studien diskuterar hur spelifierad reklam, ett så kallat advergame som kombinerar spel ochreklam, kan påverka användarnas engagemang på en plattform såsom Youtube. En prototypskapades med målet att illustrera hur spelifierad reklam på en videoplattform kan se ut. Studiensavsikt är att få en förståelse för hur användarnas attityd till reklam påverkar och influerar derasengagemang till att interagera med ett advergame på en videoplattform. Vidare är studiens syfteatt utvärdera vilka spelelement som påverkar användares engagemang i ett advergame. Studienanvände sig av kvalitativa metoder samt prototyputveckling. Prototypen utvecklades under tvåiterationer och det genomfördes även fyra användbarhetstester för att förbättra prototypen.Därefter testades prototypen i en fokusgrupp och i tre par-intervjuer. Intervjuerna genomfördespå plats i två städer i sydvästra Skåne. Resultatet bidrog med insikter om hur personerinteragerar med digital reklam och deras tankar kring ett advergame. Responsen frånintervjuerna indikerade att det inte är lämpligt att använda advergames på en videoplattform pågrund av att det stör användarens intention till varför de är på Youtube. Vidare dras slutsatsenatt spelelement som ledartavla, poäng och medaljer främjar engagemang och uppmuntraranvändaren till att interagera med ett advergame. För att få ett tydligare resultat hade det krävtsytterligare prototyputveckling samt tester och intervjuer., The study discusses how gamified ads, a so-called advergame that combines game andadvertising, can affect user engagement on a platform like Youtube. A prototype was createdwith the aim of illustrating how gamified advertising on a video platform can be portrayed. Thepurpose of the study is to gain a better understanding regarding users' attitude towardsadvertising and how it influences their engagement to interact with an advergame on a videoplatform. Further, the intention of the study is to evaluate which game elements affect users’engagement on an advergame. The study consisted of qualitative methods and prototypedevelopment. The prototype was developed over two iterations and four usability tests were alsoconducted to improve the prototype. The prototype was then tested in a focus group and in threeinterviews made up of pairs. The interviews were held on site in two cities in southwest Skåne.The result contributed insights into how people interact with digital advertising and theirthoughts about an advergame. The response from the interviews indicated that it is notappropriate to use advergames on a video platform because it interferes with the user's intentionas to why they are on Youtube. Furthermore, it is concluded that game elements such asleaderboards, points and medals promote engagement and encourage the users to interact withan advergame. To get a clearer result, further prototype development as well as tests andinterviews are required.

This study investigated the terms used by drummers and audio engineers to describe the recorded drum kit and the processing applied to it. The main method consisted of semi-structured interviews with six professionals in the fields of drumming and audio engineering. The participants were asked to describe five musical samples of different drum kit mixes containing kick, snare and hi-hat sounds. Their descriptions along with explanations of their communication tactics were compared, resulting in explanations of fourteen semantic descriptors. The comparison of their use of the terms in the context of the samples revealed some differences depending on their professional backgrounds. The results suggested that, while audio engineers have a larger semantic lexicon in regards to the recorded drum kit, the differences in the definitions of terms had a larger degree of variation between individuals than between the respective professions.

Detta arbete undersökte hur Virtual Reality(VR) kan ha en påverkan på hur husvisningar genomförs. Undersökningen försökte ta reda på om VR kan användas för att ersätta eller komplettera fysiska husvisningar. Arbetet gick även igenom vad som är viktigt för utvecklare att tänka på för att förbättra användarnas upplevelser. Undersökningen genomfördes med flera datainsamlingsmetoder som enkäter, intervjuer och observationer av en VR-prototyp. VR-prototypensom var gjord i Unity lät testpersonerna genomföra en digital husvisning. Resultatet visade att det finns potential för den här typen av applikationer, på grund av att det kan minska vissa stressmoment för användarna. Användarna påpekade att det skulle fungera mer som en komplement till fysiska visningar på grund av att det inte ger riktigt hela bilden av huset som användarna vill ha. Med sådana applikationer finns en avsaknad av viktiga aspekter såsom bild av området och lukt.

Grafiska och musikaliska teorier kring godhet och ondska har tolkats och översatts till teorier lämpade för ljuddesign. Detta för att undersöka om en karaktärs godhet och ondska kan uttryckas endast med hjälp av ljuddesign som berättarverktyg. Genom tidigare forskning samt intervjuer som hölls med professionella ljuddesigners skapades en ljudande gestaltning som satte dessa nya teorier på prov i praktiken. Artikeln finner att dessa teorier går att översätta till ljuddesign, men att ljuddesign som berättarverktyg inte är det mest effektiva att förmedla karaktärens godhet eller ondska. Att förmedla godhet och ondska görs enligt artikeln fortfarande mest effektfullt genom musik och grafik. Eftersom godhet och ondska inom ljuddesign är ett relativt outforskat område har denna artikel börjat etablera de första stegen genom att undersöka de extrema ändarna av egenskaperna godhet och ondska., Graphic and musical theories regarding good and evil have been interpreted and translated to theories suited for sound design. This was done in order to examine if a character's good and evil traits can be expressed solely through sound design as its only narrative device. Through research and interviews held with professional sound designers, an audio-visual prototype was created to test these theories in practice. This article finds that, while these theories can be translated to sound design, this narrative tool is not the most effective in conveying good and evil, and it is still more effectful to convey this through graphic and musical theories. This is a relatively unexplored area of sound design and this article serves to establish some of the first steps by exploring the two extremes of good and evil traits.

Over the last few decades, the popularity of video games has skyrocketed thanks in part to their unique ability to engage their audience and to create empathy. Among them, serious games have an additional purpose beyond entertainment; to teach and help people. Serious games have been successfully applied in a variety of different fields, such as: education, health, tourism and also in bringing knowledge about cultural heritage. In this context, this thesis describes a serious game designed to promote Brazilian cultural heritage and increase interest in tourism. The objective of this serious game was to involve the player in an interactive virtual exploration of Brazil, in order to teach more about its rich cultures and history. Our results show that the majority of people learned something new about Brazil and became interested in traveling to Brazil, even people familiar with Brazil.

Tekniken har de senaste decennierna blivit allt mer inkorporerad i vårt moderna samhälle ochtillvaro och påverkat hur vi lever. Många nya tekniker uppmärksammas ofta med förundran ellerkritik, för att sedan efter hand gradvis integreras i vår vardag. En aktuell typ av teknik som skullekunna vara på väg till en sådan roll är den mängd artificiell intelligens som har nått nya höjderunder en mycket kort tid. För tillfället är framtiden för dessa rätt oklar, men det finns mycketspekulationer kring både potentialen kring tekniken samt risker som kan uppkomma. Oavsett hurlänge tekniken förblir aktuell i praktiken, hjälper dessa synpunkter oss att ställa viktiga frågorkring vår relation gentemot tekniken. Hur vill vi relatera till den? Hur beroende vill vi vara avden? Vad kan konsekvensen av överanvändning vara? I denna artikel har vi använt spekulativdesign för att utforska vilka möjligheter teknik och maskiner i allmänhet skulle kunna ge oss,med syfte att uppmärksamma frågor som dessa. Genom att ha gestaltat fem scenarier i olikavisioner och kontexter om en nära framtid, har vi utforskat sociala, etiska och kulturella frågorsom uppkom kring tekniken och vår tillvaro., Technology has become increasingly incorporated into our modern society and existence overthe past few decades, influencing how we live. Many new technologies are often met with awe orcriticism, only to gradually become integrated into our daily lives. One current type oftechnology that may be on its way to such a role is the abundance of artificial intelligence thathas reached new heights in a very short time. At the moment, the future of this technology issomewhat unclear, but there is much speculation regarding both its potential and the risks thatmay arise. Regardless of how long the technology remains relevant in practice, theseperspectives help us ask important questions about our relationship with technology. How do wewant to relate to it? How dependent do we want to be on it? What can be the consequences ofoveruse? In this article, we have employed speculative design to explore the possibilities thattechnology and machines, in general, could offer us, with the aim of raising awareness aboutthese questions. By depicting five scenarios in different visions and contexts of a near future, wehave explored the social, ethical, and cultural issues that arise concerning technology and ourexistence.

In this paper, we explore how activists and human rights defenders deal with datafication. This work demonstrates how data can be a valuable resource in activism and campaign planning. In addition, data and lack of data also complicate daily life for people in vulnerable positions, for example, when contacting government agencies, schools, and medical facilities . Data from four types of human rights activism formed the basis of our analysis. They include volunteers and employees of NGOs dealing with refugee and migrant issues, homelessness, poverty, sexual minorities, and women's shelters. The study was done in Sweden, where the GDPR (General Data Protection Regulation) laws limit the handling and storage of personal data. The following five major themes emerge from the analysis of data from our interview study: Affording personal integrity, Data poverty, Protective data practices, Drawing attention to data, and Systems and data routines. In addition, this study shows how activists and the organizations that they support are exposed to contradictory aspects of data; on one hand, deliberately exposing data about marginalized/minoritized groups, while on the other, making sure those groups, along with activists themselves, are not exposed. Most important, the data laws and regulations are not adjusted to the needs of the most vulnerable in society, and therefore, actions of civil disobedience are necessary to care for vulnerable populations through data.

This one-day workshop invites discussions on the role of data and data-enabled practices in addressing challenges of environmental sustainability. Fostering acts of care for the environment is a complex endeavor entailing multi-lifespan relations to people and institutions, to the environment and other non-human actors, and to existing infrastructures and processes. The workshop addresses such challenges by exploring the role of data, and the work of making them actionable for the many actors involved in protecting the environment. It will bring together interdisciplinary scholars, representatives of public institutions, activists, environmental collectives, and IT practitioners interested in the design of more sustainable futures. The workshop will discuss analytical and design issues of data-enabled sustainability, along with the practical opportunities of using data to infrastructure acts of care for the environment. The workshop will accommodate up to twenty participants and will be mainly run on-site., Extended abstract

The work involved in gathering, wrangling, cleaning, and otherwise preparing data for analysis is often the most time consuming and tedious aspect of data work. Although many studies describe data preparation within the context of data science workflows, there has been little research on data preparation in data journalism. We address this gap with a hybrid form of thematic analysis that combines deductive codes derived from existing accounts of data science workflows and inductive codes arising from an interview study with 36 professional data journalists. We extend a previous model of data science work to incorporate detailed activities of data preparation. We synthesize 60 dirty data issues from 16 taxonomies on dirty data and our interview data, and we provide a novel taxonomy to characterize these dirty data issues as discrepancies between mental models. We also identify four challenges faced by journalists: diachronic, regional, fragmented, and disparate data sources., Funding Agencies|NSERC [RGPIN-2014-06309]; Wallenberg AI, Autonomous Systems and Software Program (WASP)

Real-world event sequence data, such as activity logs, eye-tracking data, simulation data, and electronic health records, often share characteristics such as a large alphabet of events, fragmentation, noise, and high complexity which makes them difficult to analyze in their raw form. Because of this, simplification and preprocessing through various data transformations are commonly required before the data can be effectively visualized and analyzed. Existing methods for such data transformation are either manually applied and rely heavily on user expertise, or use algorithmic approaches to apply bulk operations which can imply the loss of potentially important information without users being aware. To bridge this gap, we propose a visual analytics approach that aims to successively increase the quality of noisy event sequences by supporting an interactive, context-aware application of data transformations. This is achieved by providing cues concerning the potential loss of information that transformation operations may imply and allowing users to explore, and visually assess their impact on the data. Therefore, a central feature of the approach is that users can tune the data transformation process so that important identified data characteristics are preserved. We motivate the proposed approach in the domain of air traffic control and illustrate it through a usage example, using event sequences derived by merging eye-tracking and simulator data from a human-in-the-loop simulation experiment with 14 air traffic controllers., Funding Agencies|Swedish Research Council [2020-05000]; Swedish Transport Administration through the OVaK project

The iridescent effect produced by structural color is difficult (if not impossible) to capture and print using traditional CMYK pigments. The so called RGB reflective pigments, nonetheless, generate angle-dependent colors by light interference. A layered surface structure generated by the pigments’ particles on a substrate reflects light waves of different wavelengths at different viewing angles according to the optical principle known as the Bragg Law. In this work, we have studied the influence of different halftone structures on printed images, produced with RGB reflective inks via screen printing. The main goal was to enhance the iridescence of a printed reproduction by studying the performance of different halftone algorithms on a screen printing process. We investigated the influence of different halftone structures in creating different spatial combinations of inks on a print to reproduce the image of an iridescent feathered headdress. We applied first-order, second-order, and structure-aware FM halftones to compare how they influence the reproduction of the material appearance of the object represented in the original image. The results show that the structure-ware halftones improve the representation of the image structures and details. Therefore, it could better convey the 3D surface features that produce iridescence in real feathers.

Dimensionality reduction (DR) plays a vital role in the visual analysis of high-dimensional data. One main aim of DR is to reveal hidden patterns that lie on intrinsic low-dimensional manifolds. However, DR often overlooks important patterns when the manifolds are distorted or masked by certain influential data attributes. This paper presents a feature learning framework, FEALM, designed to generate a set of optimized data projections for nonlinear DR in order to capture important patterns in the hidden manifolds. These projections produce maximally different nearest-neighbor graphs so that resultant DR outcomes are significantly different. To achieve such a capability, we design an optimization algorithm as well as introduce a new graph dissimilarity measure, named neighbor-shape dissimilarity. Additionally, we develop interactive visualizations to assist comparison of obtained DR results and interpretation of each DR result. We demonstrate FEALMs effectiveness through experiments and case studies using synthetic and real-world datasets., Funding Agencies|Knut and Alice Wallenberg Foundation [KAW 2019.0024]; U.S. National Science Foundation [ITE-2134901]; National Institute of Health [1R01CA270454-01]

Studien är en del i ett tvåårigt projekt som undersökt invånarna i Helsingborgs stads inställning till kommunens nuvarande och önskade dataanvändning och digitaliseringsarbete, specifikt vad rör AI­baseradsamkörning av förvaltningarnas invånardata. Målet har varit att ge Helsingborgs stad, liksom andra kommunder i Sverige, underlag för hur datadriven teknik kan användas på ett etiskt gott sätt, utifrån invånarnas perspektiv., Chapter in report

The public sphere faces many complex problems affecting its actors concerned with safety and fear. Furthermore, the general challenges with safety and fear are connected to a wicked problem with social implications and uncertainties, leading to public fear in the worst case. Here communication has a vital role. This study focuses on Sweden, and a wicked example is the struggle with gang violence, shootings, killings, and explosions that cause insecurity and fear in society. Hence, creating and communicating a sense of safety is thus vital to handle fear in the public sphere, and one actor to do this is the Swedish Police. This study aims to explore how the Swedish Police can, via participatory processes, understand and enhance their social media communication concerning the complexity of publicly creating a sense of safety. Therefore, in this study, Critical Making and Sensemaking are used as the theoretical lenses because of their participatory processes’ perspective. The empirical data builds on two workshops with police employees from the Police Region South [Polisregion Syd] (PRS), focusing on creating social media communication strategies to develop, understand, and strategically deepen their sense of safety communication. The workshops take a bottom-up perspective with police employees to grasp the polyphonic character and the complexity of their communication regarding creating a sense of safety in the public sphere. This study adds to the literature on public sector organizations and how strategic communication is utilized in social media communication of complex matters., Part of Jens Sjöberg's ongoing dissertation

This study aims to understand how public sector organization, in this case, the Swedish Police, communicates about public safety through their social media presence. This study utilizes a participatory process method by using critical making workshops consisting of discussions, actions, and reflections to capture participants' sensemaking processes. Thus, sensemaking is therefore used as the theoretical lens. The empirical material builds on a couple of critical making workshops with four police employees from the Police Region South [Polisregion Syd] in each session, focusing on creating social media communication strategies. This is achieved to develop, understand, and strategically deepen the sense of safety by taking a bottom-up perspective to grasp the polyphonic character and the complexity of the communication., Work in progress that was presented on May 25, 2023., Part of Jens Sjöberg's ongoing dissertation.

This study aims to understand how the Swedish Police, which is an authoritarian public sector organization, communicates about public safety through their social media presence. This study utilizes a participatory process method by using critical making workshops consisting of discussions, actions, and reflections to capture participants’ sensemaking processes. Thus, sensemaking is therefore used as the theoretical lens. The preliminary findings in this paper build on four critical making workshops with three to four police employees from the Police Region South [Polisregion Syd] (PRS), focusing on reflecting and creating social media communication strategies. This is to strategically deepen the social media communication about a sense of safety by taking a bottom-up perspective to grasp the polyphonic character and the complexity of the communication., Work in progress that was presented on August 18, 2023, Part of Jens Sjöberg's ongoing dissertation.

This paper examines how individual police officers use social media as part of their communication routines and what strategies generate. Specifically, this study focuses on how police officers balance between presentations of their personal and professional lives on Instagram or TikTok by using content analysis methodology of 20 posts from Finnish and Swedish police officers. This paper adds to the literature on strategic communication and digital public sector communication. The results build an understanding about the possible challenges that may follow as public sector organizations and authorities utilize social media in their strategic communication and seek to connect with the public in more personal ways., Work in progress.
