Through the proposed game, we explore the interaction between players in an online multiplayer game using an AR HMD, which is enjoyable and has a high social presence. For this exploration, we created a game design that actively utilizes a physical environment and the asymmetry between players wearing and not wearing an HMD. We implemented the designed game and conducted a user study (n=14) to evaluate the game using the Game Experience Questionnaire and an our own questionnaire. The results revealed that the players had a highly positive affect toward the game and showed a high social presence. We also obtained insights into how to make the game more interesting and to increase social presence of players.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing → Interaction design theory, concepts and paradigmsHuman centered computing → Interaction design theoryconcepts and paradigms10.2312/egve.202413725 pages
