身体接触をインタフェースとするブレスレット型ゲームコントローラの設計

Recent multiplayer video games (MPVGs) incorporate social behaviors, such as gathering in specific locations (e.g., Niantic’s Pok´emon Go) and engaging face-to-face interactions (e.g., Nintendo’s 1-2-Switch). Interpersonal touch, known as social behavior with minimum physical distance that facilitates social interactions, is a key interaction for the MPVG design. In this study, we develop the MPVG system that utilizes players’ interpersonal touch as an interface. Thus far, we built techniques for smart bracelet devices to measure interpersonal hand-to-hand contacts and spatially control vibrotactile sensations within the hands. This paper reports the design of bracelet-type game controllers based on our techniques. The controllers send the players’ contact states as input to the MPVG in addition to button press/release and motion measured by the inertial measurement unit while receiving the command values for the vibrator and LED as output from the MPVG.
