Abstract

We constructed informational support system based on massive sensor data in a room. In the room, called "Sensing Room", approximate 600 sensors are distributed. Pressure sensors are embedded in a floor, a table, chairs and bed. Switch sensors and electric current sensors are attached on furniture and electric appliances. RFID tag readers are embedded into room planes. The room monitors human activities without restriction of occupants. Information support system includes steerable active projector on the ceiling. The projector displays information on all planes of the room. The occupant watch information wherever he/she exists in the room without restriction. Based on captured activities, information support system decides timing, position and contents fitting the occupants' activities. In this way, massive sensors data achieves attentive support. We demonstrate notification, decision support and navigation by informational support system.
