Abstract: 
In this paper we describe the concept of Social Panoramas that combine panorama images, Mixed Reality, and wearable computers to support remote collaboration. We have developed a prototype that allows panorama images to be explored in real time between a Google Glass user and a remote tablet user. This uses a variety of cues for supporting awareness, and enabling pointing and drawing. We conducted a study to explore if these cues can increase Social Presence. The results suggest that increased interaction does not increase Social Presence, but tools with a higher perceived usability show an improved sense of presence.
