Abstract

inter-glow is a system that facilitates close interaction and communication among users in real spaces by using multiplexed visible-light communication technology. By pointing light to shine on an object contains 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 show the technology plain. In our prototype, when users shine lamps on a table in a miniature living room, the system recognizes which lamps are illuminated the table. According to the combination of illuminating lamps, the system produces family conversations.
