Social presence with virtual glass

Abstract

Collaborative Virtual Environments (CVE) with co-located or remote video communication functionality require a continuous experience of social presence. If, at any stage during the experience the communication interrupts presence, then the CVE experience as a whole is affected - spatial presence is then decoupled from social presence. We present a solution to this problem by introducing the concept of a virtualized version of Google Glass™ called Virtual Glass. Virtual Glass is integrated into the CVE as a real-world metaphor for a communication device, one particularly suited for collaborative instructor-performer systems. In a study with 65 participants we demonstrated that the concept of Virtual Glass is effective, that it supports a high level of social presence and that the social presence is rated higher than a standard picture-in-picture videoconferencing approach for certain tasks.
