We also develop a VR attraction, ''Element Magic Genesis,'' as an application of this method. In this application, two users participate, with one as a player and the other as the audience. The player's abilities are enhanced based on the intensity of the audience's EMG signals. This attraction allows them to have a more immersive and unitary sense while interacting in a VR environment.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing → Virtual reality, Collaborative interactionHuman centered computing → Virtual realityCollaborative interaction10.2312/egve.202414032 pages
