Prior research has offered a plethora of wearables centred around sensing bodily actions ranging from more explicit data, such as movement and physiological response, to implicit information, such as ocular and brain activity. Bodily augmentations that physically extend the user's body along with altering body schema and image have been proposed recently as well, owing to factors such as accessibility and improving communication. However, these attempts have usually consisted of uncomfortable interfaces that either restrict the user's movement or are intrusive in nature. In this work, we present Pneunocchio, a playful nose augmentation based on the lore of Pinocchio. Pneunocchio consists of a pneumatic-based inflatable that a user wears on their nose to play a game of two truths and a lie. With our work, we aim to explore expressive bodily augmentations that respond to a player's physiological state that can alter the perception of their body while serving as an expressive match for a current part of the body.

Most digital bodily games focus on the body as they use movement as input. However, they also draw the player's focus away from the body as the output occurs on visual displays, creating a divide between the physical body and the virtual world. We propose a novel approach - the "Body as a Play Material"- where a player uses their body as both input and output to unify the physical body and the virtual world. To showcase this approach, we designed three games where a player uses one of their hands (input) to play against the other hand (output) by loaning control over its movements to an Electrical Muscle Stimulation (EMS) system. We conducted a thematic analysis on the data obtained from a field study with 12 participants to articulate four player experience themes. We discuss our results about how participants appreciated the engagement with the variety of bodily movements for play and the ambiguity of using their body as a play material. Ultimately, our work aims to unify the physical body and the virtual world.

Spectating digital games can be exciting. However, due to its vicarious nature, spectators often wish to engage in the gameplay beyond just watching and cheering. To blur the boundaries between spectators and players, we propose a novel approach called "Fused Spectatorship", where spectators watch their hands play games by loaning bodily control to a computational Electrical Muscle Stimulation (EMS) system. To showcase this concept, we designed three games where spectators loan control over both their hands to the EMS system and watch them play these competitive and collaborative games. A study with 12 participants suggested that participants could not distinguish if they were watching their hands play, or if they were playing the games themselves. We used our results to articulate four spectator experience themes and four fused spectator types, the behaviours they elicited and offer one design consideration to support each of these behaviours. We also discuss the ethical design considerations of our approach to help game designers create future fused spectatorship experiences.

Bodily games often use players' physiology as input to provide output via screen-based modalities. Game design researchers could extend the use of the body as input and output (I/O) by using body-actuating technologies such as Electrical Muscle Stimulation (EMS). EMS works by passing a small amount of electricity via electrodes attached to the player's body, contracting their muscles to actuate involuntary body movements. Our work explores this bodily I/O by creating three "body-actuated play"systems ranging from single-player to social game experiences. Ultimately, by studying the associated user experiences of these systems, we will deduce a prescriptive design framework for designing bodily games in which humans can use their bodies as input and output.

Our gastrointestinal health is influenced by complex interactions between our gut bacteria and multiple external factors. A wider understanding of these concepts is vital to help make gut-friendly decisions in everyday life; however, its complexity can challenge public understanding if not approached systematically. Research suggests that board games can help to playfully navigate complex subjects. We present Gooey Gut Trail (GGT), a board game to help players understand the multifactorial interactions that influence and sustain gut microbial diversity. Through the embodied enactment of in-game activities, players learn how their habits surrounding diet, physical activity, emotions, and lifestyle influence the gut microbial population. A qualitative field study with 15 participants revealed important facets of our game design that increased participants' awareness, causing them to reflect upon their habits that influence gut health. Drawing upon the study insights, we present five design considerations to aid future playful explorations on nurturing human-microbial relationships.

Body-actuating technologies such as Electrical Muscle Stimulation (EMS) can actuate multiple players simultaneously via physical touch. To investigate this opportunity, we designed a game called "Touchmate". Here, one guesser and two suspects sit across with their legs hidden under a table. The guesser attaches a ground electrode from one EMS channel, and each suspect attaches one active electrode from the same channel on their forearms. When a suspect touches the guesser's leg, their bodies complete the electrical circuit, actuating both their hands involuntarily via the EMS. The guesser's goal is to determine who touched their leg. In this paper, we present the results from our initial study and articulate three player experience themes. Ultimately, we hope our work inspires game designers to create physical touch games using body-actuating technologies.

People often acquire souvenirs and photographs to facilitate remembering, but possessions and memories can relate to each other in a variety of ways. This review paper presents four different connection types found between meaningful things in our everyday lives and our personal memories. Each connection type either focuses on possessions or memories and the connection between the two is either active or lost. These perspectives will be detailed through examples of studies and design cases from different fields and research areas. More studies have been found focusing on existing connections between possessions and memories, such as in human-computer interaction, design, material culture, psychology and marketing, than those lost, which were specifically focused around ageing, forgetting, heirlooms, identity and hoarding behaviour. Our review of connections between possessions and memories accumulate to suggest the attachment people ascribe to certain possessions is mirrored by the ability of objects to fulfil people's desire to preserve, embody, showcase and recollect certain memories.

People engage in sportive activities for reasons beyond improving their athletic performance. They also seek experiences like fun, adventure, a feeling of oneness, clear their heads, and flow. Since sport is a highly bodily experience, we argue that taking an embodied interaction perspective to inspire interaction design of sports systems is a promising direction in HCI research and practice. This workshop will address the challenges of designing interactive systems in the realm of sports from an embodied interaction perspective focusing on athletes' experience rather than performance. We will explore how interactive systems enhance sports experience without distracting from the actual goal of the athlete, such as freeing the mind. We will focus on several topics of interest such as sensory augmentation, augmented experience, multi-modal interaction, and motor learning in sports.

Despite their prevalence and significance in people's lives, these devices are often perceived to be highly replaceable. From a sustainability perspective, there is value in creating technological products with meaning directly associated with their materiality to reduce the rate of product consumption. We set out to explore the potential for design to promote the formation of product attachment by creating technological devices with meaningful materiality, closely integrating the physical form with the significance of its digital contents. We used the life stories and ongoing input of our intended user as inspiration for the creation of Melo, a bespoke music player. The evaluation and critical reflection of our design process and resulting artefact are used to propose a design strategy for promoting product attachment within the growing sector of technological devices.

© 2020 Association for Computing Machinery. Teachers are increasingly being encouraged to embrace evidencebased practices. Learning analytics (LA) offer great promise in supporting these by providing evidence for teachers and learners to make informed decisions and transform the educational experience. However, LA limitations and their uptake by educators are coming under critical scrutiny. This is in part due to the lack of involvement of teachers and learners in the design of LA tools. In this paper, we propose a human-centred approach to generate understanding of teachers' data needs through the lens of three key principles of translucence: visibility, awareness and accountability. We illustrate our approach through a participatory design sprint to identify how teachers talk about classroom data. We describe teachers' perspectives on the evidence they need for making better-informed decisions and discuss the implications of our approach for the design of human-centred LA in the next years.

Reflection is of increasing interest in HCI as it has many potential benefits in design, education and everyday life. In this paper, we explore media-supported reflection through the design and deployment of three concepts. In contrast to prevalent reflective approaches that are based on system-collected data, we explore how user-created media can support personal reflection. Three interactive prototypes were developed, focusing on different modalities: Balance uses audio, Cogito uses text, and Dott uses visual media. We evaluate these concepts in an inthe-wild study that is both explorative and comparative. We found that the open-ended systems primarily supported reflection during the creation of media and that the use depended on opportunity and triggers. We conclude the paper with a discussion of our findings regarding the method and the implications of our findings for the broader area of design for reflection.

There is mounting evidence acknowledging that embodiment is foundational to cognition. In HCI, this understanding has been incorporated in concepts like embodied interaction, bodily play, and natural user-interfaces. However, while embodied cognition suggests a strong connection between motor activity and memory, we find the design of technological systems that target this connection to be largely overlooked. Considering this, we are provided with an opportunity to extend human capabilities through augmenting motor memory. Augmentation of motor memory is now possible with the advent of new and emerging technologies including neuromodulation, electric stimulation, brain-computer interfaces, and adaptive intelligent systems. This workshop aims to explore the possibility of augmenting motor memory using these and other technologies. In doing so, we stand to benefit not only from new technologies and interactions, but also a means to further study cognition.

Personal photo collections have grown due to digital photography and the introduction of smartphones, and photo collections have become harder to manage. Deleting photos appears to be difficult and the task of curation is often perceived as not enjoyable. The lack of curation can make it harder to retrieve photos when people need them for various reasons, such as individual reminiscing, shared remembering or self-presentation. In this study we investigate how we can stimulate people to organise their photo collections on their smartphones. Ten participants evaluated and qualitatively compared four applications with different characteristics regarding voting on and deleting photos. We found that voting on photos is easier and more enjoyable in comparison to deleting photos, that participants showed reminiscence while organising, that deleting can be frustrating, that participants have different preferences for sorting and viewing photos and that voting could make deleting and retrieving easier.

© The Author(s) 2017. We are surrounded by personal items that can trigger memories, such as photos, souvenirs and heirlooms. Also during holidays, we collect items to remind us of the events, but not all bring back memories to the same extent. Therefore, we explored peoples’ responses to personal items related to a holiday, using the home tour interviewing method. In total, 63 accounts of cuing responses from nine home tours were analysed using thematic analysis. This resulted in four types of cuing responses: (a) ‘no-memory’ responses, (b) ‘know’ responses, (c) ‘memory evoked think or feel’ responses and (d) ‘remember’ responses. For each of these cuing response categories, we looked into the types of items and their characteristics. Furthermore, we found that some items can evoke multiple memories. The majority of the memories’ content refers to events close to the moment of acquiring the item.

© 2019 Association for Computing Machinery. Devices such as phones, laptops and tablets have become central to the ways in which many people communicate with others, conduct business and spend their leisure time. This type of product uniquely contains both physical and digital components that affect how they are perceived and valued by users. This article investigates the nature of attachment in the context of technological possessions to better understand ways in which designers can create devices that are meaningful and kept for longer. Findings from our study of the self-reported associations and meaningfulness of technological possessions revealed that the digital contents of these possessions were often the primary source of meaning. Technological possessions were frequently perceived as systems of products rather than as singular devices. We identified several design opportunities for materialising the associations ascribed to the digital information contained within technological products to more meaningfully integrate their physical and digital components.
