In this project, we explore the intersection of improvisational theater and Twitch live streaming. Improv offers social affordances to live streams, while streaming offers improv performers a way to both broaden their reach to non-copresent audiences and create new types of participatory improv games. Based on insights from both domains, we present StAGE, a live streaming system that both communicates performative information otherwise lost when streaming live theater and accommodates participatory roles for performers, hosts, and audiences. Using our system, we created and playtested four improv game prototypes exploring a range of interactions. We show that StAGE affords novel interactions both as a streaming experience and as improvisational theater. We propose that the social transfer of roles and information, particularly by hosts, is a critical aspect of the design. We conclude by discussing newly discovered challenges and potential for the future of the intersection of these domains.

This paper broadens understanding of intuitive use in games by testing the influence of three naturally mapped motion control interfaces in the context of a tennis video game. It also extends exploratory work on natural mapping and intuitive interaction in video games by refining instruments to measure game technology familiarity. Repeated-measures experiment data (N = 120) is analysed via mixed ANOVAs with four distinct player characteristic variables. As with broader intuitive interaction research, results show that more familiar players performed more effectively; however, where differences exist, they point towards increased intuitive use gains with more naturally mapped control interfaces. Subjective measures suggest that control interfaces were perceived as more intuitive when they had higher levels of natural mapping, yet also point to the influencing roles of familiarity and the dimensions of the control types in shaping these perceptions.

Personalization is essential for gameful systems. Past research showed that the Hexad user types model is particularly suitable for personalizing user experiences. The validated Hexad user types questionnaire is an effective tool for scientific purposes. However, it is less suitable in practice for personalizing gameful applications, because filling out a questionnaire potentially affects a person's gameful experience and immersion within an interactive system negatively. Furthermore, studies investigating correlations between Hexad user types and preferences for gamification elements were survey-based (i.e.,not based on user behaviour). In this paper, we improve upon both these aspects. In a user study (N=147), we show that gameful applications can be used to predict Hexad user types and that the interaction behaviour with gamification elements corresponds to a users' Hexad type. Ultimately, participants perceived our gameful applications as more enjoyable and immersive than filling out the Hexad questionnaire.

The shape and function of the human hand are intimately linked to our interaction with the physical world and sets us apart from our evolutionary ancestors. In the digital age, our hands still represent our main form of interaction. We use our hands to operate keyboards, mice, trackpads, and game controllers. This modality, however, separates content display and interaction. In this paper, we present Digital Gloves (DigiGlo), a system designed to evaluate the benefits of a unified hand display and interaction system. We explore this symbiosis in the context of gaming where users control games using hand gestures while the content is displayed on their bare hand. Building on established learning principles, we explore different hand gestures and other specially tailored interactions, through three carefully designed activities and two user studies. From these we show that this is an idea that has the potential to bring more intuitive, enjoyable, and effective gaming and learning experiences, and offer recommendations regarding how to better design such systems.

The increasingly popular social virtual reality (VR) is dramatically transforming how people meet, interact, and socialize online. These immersive digital spaces blend aspects of the online and offline worlds, creating new opportunities for online interactivity. Yet, questions still remain about what individuals actually do in social VR and how they envision and reflect on the design of social VR technologies. In this paper, we report our findings of an interview study (N=30)that investigated what made activities on these platforms meaningful to users as well as users' recommendations for designing social VR to better support such activities. Our findings expand current literature on social dynamics and sociality in online digital spaces by focusing on social VR. We also inform future design directions to create more socially supportive and satisfying social VR space.

Visualizations have become a relevant instrument in games user research and analytics as well as for players to facilitate the analysis of behavioral data, including the evaluation of spatial game metrics. A fundamental task in this respect is to understand how different metrics vary across the game environment and how they relate to each other. In this paper, we evaluate a visualization based on hexagonal binning paired with visual glyphs to represent multivariate information. To study how much information can be encoded in a reasonable manner we created variants with varying complexity and measured correctness and efficiency for different types of tasks through an online study (N = 197). Our results indicate that players appreciated the clear display of multivariate data but that correctness and efficiency were also largely influenced by the visual coding and the task at hand. Based on gained insights, we discuss implications for the design of such and similar gameplay visualizations.

Players, developers, and researchers generally agree that "cheating" to gain an unfair advantage over others fosters negative player experiences. Despite social and experiential repercussions and cheating's negative stigma, the majority of players regularly cheat in some form. Fixation on cheating's social and moral axes disservices understanding the ways in which players cheat in single-player settings, cheating's potential benefits, and cheating's effects on player experience. Surveying 188 U.S. players on their beliefs, preferences, and experiences of cheating in single-player contexts, mixed-methods analyses reveal that, unlike in multiplayer contexts, most players endorse cheating in single-player settings. They do so to facilitate mood repair, stress relief, and flow, and to exercise agency over satisfying their psychological needs during gameplay. Building off prior studies in support of cheating, we discuss the ludic, cognitive, and wellness benefits found, and argue against imposing the moral dilemmas of multiplayer cheating on single-player contexts.

Designing for bodily play in HCI is increasingly gaining attraction, including research on the experiential dynamics leading to that. Within this research, however, there has been little investigation into the differences between bodily playing and bodily gaming and associated implications for design. This paper investigates such differences and proposes an understanding derived from the Danish linguistic connotations of the four different combinations of bodily "playing/gaming" a "play/game". We exemplify these through four different examples and extract four strategies for designers to implement in their future bodily designs. With our work, we hope we are able to expand the range of diverse bodily play and game experiences within HCI.

Customization interfaces allow players to tailor character appearance to represent desired self-concepts, increasing character identification and contributing towards enjoyment. Yet, despite their ubiquity, such interfaces seldom allow modification of non-player characters (e.g., in-game enemies). A between-subjects experiment (N=34) examined affective/cognitive responses to customizing and destroying enemies in a custom-built game. Participants created characters representing either a positive (confidence) or negative (anxiety) self-concept, and subsequently destroyed it during gameplay. Players reported greater identification, attitudes, enjoyment, and reduction in negative affect (anxiety) when customizing characters representing confidence, whereas anxiety characters increased negative affect. Affective responses to destruction varied based on self-concept. Destroying confidence characters increased negative affect, whereas negative affect was slightly reduced after destroying anxiety characters. Both groups evaluated the game favorably and exhibited similar purchase intentions. Results suggest that players prefer creating enemies in their (ideal) image like they do their own avatars. Avenues for future research are discussed.
