In the broad design space of telepresence systems, we are interested in contexts where users collaborate over a shared workspace. Our work involving connecting distributed touch surfaces (e.g. distributed tabletops) has shed light on the problem of supporting reference space—the ability of collaborators to point at, and refer to objects in the workspace. A promising approach to support this gestural communication has been to capture video of users’ arms as they work over the surface, transmitting and overlaying that video at remote workstations. The problem with this approach is that the video image is a flat projection of users’ 3D bodies, limiting the expressiveness of users’ gestures, and occasionally providing false information. In our most recent work, we have begun exploring â€?non-photorealisticâ€? visualizations of users’ bodies to support expressiveness in reference space.
