DOI

In this paper, we present a novel collaboration tool, OmniGlobeVR, which is an asymmetric system that supports communication and collaboration between a VR user (occupant) and multiple non-VR users (designers) across the virtual and physical platform. OmniGlobeVR allows designer(s) to explore the VR space from any point of view using two view modes: a 360° first-person mode and a third-person mode. In addition, a shared gaze awareness cue is provided to further enhance communication between the occupant and the designer(s). Finally, the system has a face window feature that allows designer(s) to share their facial expressions and upper body view with the occupant for exchanging and expressing information using nonverbal cues. We conducted a user study to evaluate the OmniGlobeVR, comparing three conditions: (1) first-person mode with the face window, (2) first-person mode with a solid window, and (3) third-person mode with the face window. We found that the first-person mode with the face window required significantly less mental effort, and provided better spatial presence, usability, and understanding of the partner’s focus. We discuss the design implications of these results and directions for future research.
