Abstract
This paper contributes to building a standard process of research and development (R&D) for new user experiences (UX) in metaverse services. We tested this R&D process on a new UX proof of concept (PoC) for Meta Quest head-mounted display (HMDs) consisting of a school-life karaoke experience with the hypothesis that it is possible to design the avatars with only the necessary functions and rendering costs. The school life metaverse is a relevant subject for discovering issues and problems in this type of simultaneous connection. To qualitatively evaluate the potential of a multi-person metaverse experience, this study investigated subjects where each avatar requires expressive skills. While avatar play experiences feature artistic expressions, such as dancing, playing musical instruments, and drawing, and these can be used to evaluate their operability and expressive capabilities…
