PixIO: sharing any surface

Task and reference spaces are important channels of communication for remote collaboration. A number of systems exist for sharing these spaces, but all of them have an inherent flaw: none can share arbitrary physical and digital objects on arbitrary surfaces. We have created PixIO, a new cost-effective, light-weight peripheral device that solves this problem. It shares hand gestures and arbitrary objects, such as notes, drawings, and digital documents, on arbitrary surfaces, such as tables and whiteboards.
