This project, called “Reddot”, reacts to human interaction in the lobby of an office building by displaying color flows in a three-dimensional plexiglass grid that tracks pedestrians as they walk by. The project uses a unique form of presence detection by projecting lasers onto people’s bodies and tracking how far they are from its face, also it writes incoming SMS messages sent by visitors on its 3D display. Check out more technical details and a nice “exploded” view of the structure at the link below.
