Lumisight table: a face-to-face collaboration support system that optimizes direction of projected information to each stakeholder

The goal of our research is to support cooperative work performed by stakeholders sitting around a table. To support such cooperation, various table-based systems with a shared electronic display on the tabletop have been developed. These systems, however, suffer the common problem of not recognizing shared information such as text and images equally because the orientation of their view angle is not favorable. To solve this problem, we propose the Lumisight Table. This is a system capable of displaying personalized information to each required direction on one horizontal screen simultaneously by multiplexing them and of capturing stakeholders' gestures to manipulate the information.
