Conceptual illustration of our implemented PanoVC prototype. (Left) A user of our PanoVC system (the local user) shares the environment by capturing it with the mobile phone, (Middle) a distant user (the remote user) receives a camera stream, and builds and updates a panoramic representation of the distant environment. Using orientation tracking the phone becomes a window into the distant environment as both users can independently control their current view. (Right) By providing a window into the distant environment, users of PanoVC experience the feeling of presence as they are virtually "being there together".
Abstract: We are presenting PanoVC - a mobile telepresence system based on continuously updated panoramic images. We are showing that the experience of telepresence, i.e. the sense of "being there together" at a distant location can be achieved with standard state-of-the-art mobile phones. Because mobile phones are always on hand users can share their environments with others in a pervasive way. Our approach is opening up the pathway for applications in a variety of domains such as the exploration of remote environments or novel forms of videoconferencing. We present implementation details, technical evaluation results, and the findings of a user study of an indoor-outdoor environments sharing task as proof of concept.
