Head-mounted displays (HMDs) increase immersion in virtual world, however which limits VR audiences’ awareness of the external audiences that co-located in the same physical environment. In this paper, we propose a shareable VR experience between VR audiences and external audiences by superimposing the virtual world onto physical environment via a portable projected interface, thereby enabling external audiences to observe and interact with the virtual objects by using hand gestures. Our system allows external audiences to explore the virtual scenario spatially and to generate asymmetric communication with VR audiences. These design strategies could be adapted for future shareable VR experience.
