Mining Player Experience Trends From Game Reviews Using Large Language Models

How have player experiences changed over the years? For instance, have there been general shifts in what kinds of emotions players experience and express? We probe these questions with help of recent methodological advances in psychology and Large Language Models (LLMs), in particular the possibility to predict Likert…

"Don't You Dare Go Hollow": How Dark Souls Helps Players Cope with Depression, a Thematic Analysis of Reddit Discussions

Entertainment videogames have been recognized for their potential therapeutic benefits, but there is a need for more in-depth, game-specific explorations of the game features that could contribute to such benefits. This study examines how players of Dark Souls describe the game as helping them cope with depression. We…

SIM2VR: Towards Automated Biomechanical Testing in VR

Automated biomechanical testing has great potential for the development of VR applications, as initial insights into user behaviour can be gained in silico early in the design process. In particular, it allows prediction of user movements and ergonomic variables, such as fatigue, prior to conducting user studies. Ho…

WAVE: Anticipatory Movement Visualization for VR Dancing

Dance games are one of the most popular game genres in Virtual Reality (VR), and active dance communities have emerged on social VR platforms such as VR Chat. However, effective instruction of dancing in VR or through other computerized means remains an unsolved human-computer interaction problem. Existing approaches…

Comic-making to Study Game-making: Using Comics in Qualitative Longitudinal Research on Game Development

This paper reports the research method of the “Game Expats Story (GES)” project that used qualitative longitudinal research (“QLR”) incorporated with art-based research (“ABR”) in the context of game research. To facilitate greater participant engagement and a higher retention rate of longitudinal participants, we cre…

Grand Challenges in SportsHCI

The field of Sports Human-Computer Interaction (SportsHCI) investigates interaction design to support a physically active human being. Despite growing interest and dissemination of SportsHCI literature over the past years, many publications still focus on solving specific problems in a given sport. We believe in the b…

Evaluating Large Language Models in Generating Synthetic HCI Research Data: a Case Study

Collecting data is one of the bottlenecks of Human-Computer Interaction (HCI) research. Motivated by this, we explore the potential of large language models (LLMs) in generating synthetic user research data. We use OpenAI’s GPT-3 model to generate open-ended questionnaire responses about experiencing video games as ar…

Breathing Life Into Biomechanical User Models

Forward biomechanical simulation in HCI holds great promise as a tool for evaluation, design, and engineering of user interfaces. Although reinforcement learning (RL) has been used to simulate biomechanics in interaction, prior work has relied on unrealistic assumptions about the control problem involved, which limits…

Personalized Game Difficulty Prediction Using Factorization Machines

The accurate and personalized estimation of task difficulty provides many opportunities for optimizing user experience. However, user diversity makes such difficulty estimation hard, in that empirical measurements from some user sample do not necessarily generalize to others. In this paper, we contribute a new appr…

Vibing Together: Dance Experiences in Social Virtual Reality

Dancing is a universal human activity, and also a domain of enduring significance in Human-Computer Interaction (HCI) research. However, there has been limited investigation into how computing supports the experiences of recreational dancers. Concurrently, a diverse and sizeable dance community has been emerging in VR…
