GalVR: A Novel Collaboration Interface using GVS

GalVR is a navigation interface that uses galvanic vestibular stimulation (GVS) during walking to cause users to turn from their planned trajectory. We explore GalVR for collaborative navigation in a two-player virtual reality (VR) game. The interface affords a novel game design that exploits the differences in first and third-person perspectives, allowing VR and non-VR users to share a play experience. By introducing interdependence arising from dissimilar points of view, players can uniquely contribute to the shared experience based on their roles. We detail the design of our asymmetrical game, Dark Room and present some insights from a pilot study. Trust emerged as the defining factor for successful play.  [Publication Available]
