Simulating an earthquake-damaged house, the floor is tilted 15°-18° while interior fittings stay perpendicular or parallel to the floor. Standing on the tilted floor, visitors lose balance and spatial orientation, experiencing how hard it is to move and the dizziness a quake causes, deepening their understanding of earthquake hazards and the difficulty of escape. Composition: infrared sensor, time controller, voice controller, strobe light, smoke machine, air compressor and control system.
