Informational support in distributed sensor environment sensing room

This work describes an informational support system based on room-type behavior measurement environment 'sensing room' and active image projector. In the room, there are a floor and some other furniture with embedded pressure sensors, electric appliances with their usage sensors, and tag sensors, which identify objects in the room. Using these embedded sensors, the room is able to recognize the state of the habitant in the room. Based on the status and the habitant's personal profile accumulated, the room determine the timing and the content to perform informational support for the habitant. The information is properly displayed by the pan-tilt enabled image projector utilizing image distortion correction method. Some typical supporting scenario are shown as examples.
