Introduction: One way to improve exercise performance and protect heart health is the extended synchronization of the stepping with the diastolic phase of the cardiac cycle. Cardiac-locomotor coupling (CLC) happens when the step rate (SR) equals the heart rate (HR). The extent of CLC in daily life is unknown. This study aims to analyze spontaneous occurrences of CLC during daily activities. Methods: A retrospective analysis of daily life recordings from a wrist-worn sensor was undertaken (PMData, N = 16, 5 months duration). The deviation between HR and SR was used to define CLC (deviation ≤ 1%) and weak CLC (1%< deviation ≤ 10%). The occurrence and the probability of CLC during everyday life were computed from the recordings. The CLC occurrences were stratified depending on the duration and intensity of the physical activity. Finally, a Monte Carlo simulation was run to evaluate the probability of random occurrences of CLC vs. the observed recordings. Results: Participants couple for 5% and weakly couple for 35% of the observational period. The ratio of 1:1 between HR and SR is the dominating occurrence across the study population and this overrepresentation is significant. CLC occurs mostly for long activities. The extent of CLC for various intensities of activity is subject-dependent. The results suggest that CLC is feasible for most people. Conclusions: CLC occurs spontaneously during unsupervised daily activity in everyone in our cohort, which suggests a mechanistic interaction between the cardiac and the locomotor systems. This interaction should be investigated for medical rehabilitation and sports applications in the future. [ABSTRACT FROM AUTHOR]

Unser Beitrag beschäftigt sich mit dem zeitgenössischen Phänomen des Lifelogging in YouTube-Fitnessvideos und -kanälen, das wir hier als exemplarisches Phänomen der von Stalder beschriebenen «Kultur der Digitalität» vorstellen wollen. In ihr entwickeln die Individuen einen zunehmend medienvermittelten Orientierungsrahmen, wie sie sich zu sich selbst, zueinander und zur Welt positionieren. Mit diesem Verhältnis von Selbst, Bezugsgruppe und Welt sind – mit Blick auf die YouTube-Fitnesskulturen – bereits Bildungsprozesse angesprochen. Diese werden wir aus der medienkompetenztheoretischen Perspektive Baackes herausarbeiten, indem wir die Potenziale eines medienpädagogischen «Klassikers» für die Analyse eines aktuellen und in die Zukunft gerichteten Medienphänomens ausloten. Dabei setzen wir den von Baacke betonten Modus des «In-der-Welt-Seins» mit Stalders Überlegungen zu den Prozessen sozialer Bedeutungsproduktion in einer Kultur der Digitalität in Verbindung und fragen nach den notwendigen Medienkompetenzen, um im Kontext des Lifeloggings in YouTube-Fitnessvideos an diesen Prozessen teilzuhaben. Insgesamt betrachten wir mit der Webformatanalyse für audiovisuelles und vernetzendes Material acht Kanäle und 16 Videos von Fitnessinfluencer:innen. Die Ergebnisse offenbaren eine geschlechtsspezifische Körperinszenierung auf YouTube und eine äusserst medienkompetente Praxis professionalisierter Videoproduktion. Ein Desiderat bleibt die Medienkritik, die die Verantwortung insbesondere gegenüber jugendlichen Rezipient:innen reflektiert. Wir diskutieren die Ergebnisse im Lichte der medienkompetenztheoretischen Perspektive auf das Lifelogging in einer Kultur der Digitalität und verorten sie abschliessend in einem erweiterten Kontext.

We address in this work the topic of broadcasting one's visual reality, captured by the video cameras embedded in mobile and wearable devices, to a remote audience. We discuss several designs of such life broadcasting systems, which we position at the intersection of lifelogging, Alternate Reality, and Cross-Reality technology. To this end, we introduce the "Alternate Reality Broadcast-Time" matrix for the broadcasting and consumption of alternate realities, in which designs of systems that implement sharing and consumption of personal visual realities can be positioned, characterized, and compared. These design options range from simple video streaming over the web using conventional video protocols to mediated and augmented reality, to audio narration and vibrotactile rendering of concepts automatically detected from video captured by wearable cameras. To demonstrate the usefulness of our broadcast-time matrix, we describe three prototypes implementing lifelogging, concept recognition from video, augmented and mediated vision, and vibrotactile feedback. Our contributions open the way toward new applications that blend lifelogging, consumption of multimedia alternate realities, and XR technology to empower users with richer opportunities for self-expression and new means to connect with the followers of events in their lives.

The understanding of the metaverse is currently expanding, and several interpretations and implementations may be present. The many metaverse iterations have distinct components and capabilities, which have the potential to evolve and enhance over time in tandem with technological advancements and evolving user requirements. The metaverse has emerged as a widely discussed subject of public interest, with individuals and organizations alike contemplating its potential applications. However, a prevailing misperception persists over its fundamental comprehension. The concept of the metaverse is often misconstrued as solely referring to a virtual world; nevertheless, it encompasses more than simply a virtual realm. Three other categories can be classified as constituting the metaverse. The metaverse encompasses four distinct categories, each characterized by unique aspects that may or must diverge from one another. The elements play a crucial role in the development of any metaverse kind. This work aims to provide a valuable contribution by offering a comprehensive analysis of the constituent features of various metaverse types. Its purpose is to assist anyone interested in studying or implementing a certain metaverse type by fostering a deeper understanding of its core aspects. [ABSTRACT FROM AUTHOR]

Lifelogging is a form of personal data collection which seeks to capture the totality of one's experience through intelligent technology and sensors. Yet despite notable advancement in such technologies, there remain persistent challenges to developing interactive systems to analyse the types of large-scale personal collections often generated by lifelogging. In response to this, we present the Lifelog Application Design (LAD) model which is intended to address these challenges and support the design of more novel interactive systems that may target a broader range of application use cases. The model is deliberately structured to remain impartial to the specific personal data, technology platform, or application criterion, to provide maximum utility across the domain. We demonstrate this utility by exploring two case studies and a retrospective analysis of VRLE, a real-world application prototype developed to examine the potential of large-scale personal data retrieval in virtual reality. This work is based on the accumulation of insights garnered from involvement in a number of collaborative lifelogging projects over the past decade. It is our goal to encourage future researchers to utilise the LAD model to support the design and development of their own application prototypes and further solidify the model's contribution to the domain as a whole.

Self-tracking describes capturing and analysing the body and life using digital technologies. Its popularity is propelled by the widespread availability of enabling technologies like smartwatches or fitness-trackers. However, given the broad consensus on the co-productive relationship between technologies and social realities, reducing this phenomenon to technological feasibility alone would be inappropriate. This paper explores self-tracking by investigating its enculturated meanings, focusing on Western Europe. For this purpose, we analysed promises behind self-tracking technologies articulated in TV-commercials considering their relation to the late-modern socio-material constitution. The findings suggest that self-tracking addresses several ideal-typical late-modern problems, like the contingency of everyday living. Self-tracking technologies promise to counteract these problems by employing number-based rationalisation strategies. They aim to increase and condense performance capacities and activate the users. Thereby, they turn out to be technologies of an instrumental reason attempting to counter collective issues by optimising the individual.

In this paper we make a case for 'Little Data', which is real-time, self-collected, idiosyncratic datasets maintained by individuals about themselves on myriad topics. We develop and offer a methodology for combining these messy, highly personal insights, to make deductive observations about collective practices. In testing this approach, we use the case study of the 2020–21 stay-at-home orders imposed in the U.S.A., U.K., and Western Europe during the Coronavirus pandemic to operationalise and demonstrate the applicability of this method. Our main finding is to show that whilst stay-at-home orders did have a significant impact on habits during the COVID-19 pandemic, these changes were often counterintuitive, of an insightful nature on topics that would otherwise not be investigated, and always short-lived. Our main contribution is to present Little Data, despite and because of its fragmented and disparate nature, as a viable and useful tool to understand personal habits at finite junctures.

In this extended paper, we describe our lifelog retrieval system called Memento which participated in the 2021 Lifelog Search Challenge in detail. Memento leverages semantic representations of images and textual queries projected into a common latent space to facilitate effective retrieval, aiming to bridge the existing semantic gap between complex visual scenes/events and user information needs expressed as textual and faceted queries. Our system also has a minimalist user interface which includes functionalities such as visual data filtering and temporal search. Finally, we include a comparative analysis of Memento's performance at LSC 2021 and suggest improvements for future iterations of the system. [ABSTRACT FROM AUTHOR]

Background: The World Health Organization (WHO) reported that the proportion of senior citizens (over 60 years old) in the world population will reach 30% by 2050. Governments with rapidly ageing societies, such as Japan, urge local communities to develop sustainable solutions that facilitate healthy ageing. A vital component of the solution is for individuals to self-monitor their daily activities and health statuses. With advances in wearable devices, the self-monitoring practice of lifelogging, has become accessible for many people, making such devices promising tools for senior citizens. However, the current understanding of the effective practices of supporting senior citizens through lifelogging technologies is still limited. Methods: This article reports the findings of a study that investigated the feasibility and effectiveness of a lightweight GPS-based lifelogging approach exercised by senior citizens in Japan. We asked ten participants to carry a smartphone when they went out, and the device automatically captured their activity and location data. We also generated monthly personalised reports to help participants reflect on their daily lives. We analysed the log data collected by the mobile devices, answers to questionnaires distributed every month with activity reports, and final interviews. Results: The results of the analysis suggest that 1) it is feasible for senior citizens to carry a smartphone to collect their activity and location data, and participants did not feel stressed even when they did not have previous experience using the device; 2) activity reports are a promising way to help senior citizens reflect on their daily lives; 3) senior citizens can be highly atuned to erroneous numeric data captured by these devices, and 4) the ability to interpret visualisations of lifelog data can vary across participants. Conclusions: The findings of this study call for developing data literacy programs for senior citizens to facilitate their effective use of data-driven services.

One of the modern technologies with the most promise is the metaverse, according to technologists but there aren't many discussions on opportunities and challenges of the metaverse for higher education. Metaverse is defined by many educationists as the next generation of internet-based education. Since its creation, the metaverse has been viewed as a shared virtual area where simulations may work together. Users may produce material and engage in interactive experiences in the fully immersive, permanent metaverse. Educational Metaverse performs with four distinctive classes i.e. avatars, AR/VR/MR. AI, & lifelogging. Higher Education Students may have the chance to practice different skills in the metaverse, be placed in an intellectual or competence-practicing environment, be encouraged to develop and learn things that they are unable to do in the real world, and be able to collaborate and communicate with other students in the virtual world. Immersive learning experiences, personalized learning, augmented collaboration and enhanced accessibility are some of the benefits of using metaverse in higher education. Whereas, the challenges of educational metaverse in higher education include regarding nature of immersive learning experiences, Quality of teaching-learning content, virtual immersive environment, interface and interaction, and challenges regarding security and privacy of users, data, hardware and software. Students can be provided with unique and valuable learning experiences that prepare them for the opportunities and challenges of the future by utilizing the cutting-edge technology of metaverse in higher education.

This article develops the concept of 'deathlogging' as a complement to the more popular 'lifelogging' to describe how wearable cameras record fatal accidents, particularly among action sports participants. The article situates deathlogging in a history of media and communication theory interested in the relationships between life and death, and in particular the concept of forensic mediation to describe technologies capable of documenting and reconstructing accidents. The wearable GoPro camera is a camera of choice for action sports athletes to easily record and share things like BASE jumping to gain audience views and capital in the form of sponsorships. Representative examples are discussed and analyzed to demonstrate how fatal accidents transform the value of GoPro footage from social-economic capital into forensic or juridical evidence to reconstruct accidents, make sense of fatalities, and, in some instances, argue for legal culpability. The article offers deathlogging as a concept which can be applied to a variety of recording situations with different kinds of wearable cameras. [ABSTRACT FROM AUTHOR]

Interest in the metaverse has been growing worldwide as the virtual environment provides opportunities for highly immersive and interactive experiences. Metaverse has gradually gained acceptance in the medical field with the advancement of technologies such as big data, the Internet of Things, and 5 G mobile networks. The demand for and development of metaverse are different in diverse subspecialties owing to patients with varying degrees of clinical disease. Hence, we aim to explore the application of metaverse in acute medicine by reviewing published studies and the clinical management of patients. Our review examined the published articles about the concept of metaverse roadmap, and four additional domains were extracted: education, prehospital and disaster medicine, diagnosis and treatment application, and administrative affairs. Augmented reality (AR) and virtual reality (VR) integration have broad applications in education and clinical training. VR-related studies surpassed AR-related studies in the emergency medicine field. The metaverse roadmap revealed that lifelogging and mirror world are still developing fields of the metaverse. Our findings provide insight into the features, application, development, and potential of a metaverse in emergency medicine. This study will enable emergency care systems to be better equipped to face future challenges. [ABSTRACT FROM AUTHOR]

The wide availability and small size of different types of sensors have allowed for the acquisition of a huge amount of data about a person's life in real time. With these data, usually denoted as lifelog data, we can analyze and understand personal experiences and behaviors. Most of the lifelog research has explored the use of visual data. However, a considerable amount of these images or videos are affected by different types of degradation or noise due to the non-controlled acquisition process. Image Quality Assessment can plays an essential role in lifelog research to deal with these data. We present in this paper a twofold study on the topic of blind image quality assessment. On the one hand, we explore the replication of the training process of a state-of-the-art deep learning model for blind image quality assessment in the wild. On the other hand, we present evidence that blind image quality assessment is an important pre-processing step to be further explored in the context of information retrieval in lifelogging applications. We consider that our efforts have been successful in the replication of the model training process, achieving similar results of inference when compared to the original version, while acknowledging a fair number of assumptions that we had to consider. Moreover, these assumptions motivated an extensive additional analysis that led to significant insights on the influence of both batch size and loss functions when training deep learning models in this context. We include preliminary results of the replicated model on a lifelogging dataset, as a potential reproducibility aspect to be considered. [ABSTRACT FROM AUTHOR]

Visual lifelogging is the procedure that enables individuals to visually record daily life activities by means of small wearable cameras, which can be worn around the neck or on the clothing. Lifelogging devices automatically take pictures or videos after pre-set time intervals or after dynamic input changes. Although some studies have shown effectivity of reviewing lifelogging images in brain-damaged individuals with forms of amnesia as a rehabilitation tool, systematic endeavours to overview this literature is yet missing. The aim of this narrative literature review was to review all the available case-studies, experimental studies and group studies in brain-damaged individuals applying lifelogging devices in a clinical context. The included studies showed efficacy for both subjective and objective measures of memory. In mild to severe amnesia, reviewing images recorded by the lifelogging device was beneficial to subjective and objective measures of memory. Lifelogging is demonstrated to have a great potential in helping people who are suffering from memory loss. It can offer an excellent alternative to currently more frequently used memory rehabilitation techniques and can be applied more in clinical settings. [ABSTRACT FROM AUTHOR]

Considering the number of people in front of screens, especially children and adolescents, the metaverse could and should become a place of health promotion. Consequently, the objective of the present study was to review the current literature to detect articles that connected the metaverse with prevention and treatment, education and training, and research setting. (2) Methods: Articles were searched on Pubmed, Web of Science, and Scopus, including English-written papers published until 12 August 2022. They were screened against the eligibility criteria and discussed narratively. (3) Results: The literature published is poor; only 21 articles were included, and 11 of them were added in a second moment. These articles were mainly reviews of the literature or editorials. The aspects related to this virtual world in terms of health prevention and the treatment of clinical conditions, education and training, and research have been narratively discussed. (4) Conclusions: The metaverse could be considered a useful instrument to arrive easily and quickly to the population. Given its importance, today, different studies and investments are required to develop proper health promotion programs that are feasible and valid in the metaverse. [ABSTRACT FROM AUTHOR]

Sustainable tourism has become a key priority in the strategic plans for tourism development in order to attain sociocultural development and environmental preservation. This paper examines opportunities for the advancement of sustainable tourism by encouraging tourists to consider sustainability and to include sustainable options in their tourist practices. The paper adopts a practice-based approach for the understanding of tourist behavior as a series of practices tourists perform for the development of valuable experiences, usually with the support of services offered by tourist organizations and service providers. Sustainability is an option for tourists that needs to be offered, promoted, and supported when they decide on their practices and the way they will perform them. Hence, sustainability is an option that needs to be designed so that tourists are enabled and motivated to adopt sustainable tourist practices. The paper proposes the sustainable tourist journey as an approach for the analysis and design of sustainable tourist practices that is based on the holistic scope of the consumer journey. The paper contributes to the advancement of sustainable tourism by introducing and improving the understanding of sustainability concerns in tourist practices. The paper discusses also how digital technologies can support the design of sustainable tourist practices. [ABSTRACT FROM AUTHOR]
