Abstract

Inter-glow is a system that facilitates close interaction and communication among users in real space by using multiplexed visible-light communication technology. By shining light on an object containing an embedded photo sensor, users can get information about the object. In addition, several users can communicate with each other intimately by shining light on the object at the same time. We built a prototype to demonstrate the technology. In our prototype, when users point their lamps at the table in a miniature living room, the system can recognize which lamps are illuminating the table. According to the combination of illuminating lamps, the system produces the family conversations.
