The Staircase Sytem has two modes: ascending and descending. In ascending status lights are turned on below the predestrian as she goes down. In descending mode the converse is true.
The Staircase Sytem uses motion detectors and a programmable microcontroller to sense where the pedestrian is on the staircase and light treads above or below him as he progresses.
The Staircase Sytem can be programmed to have all the lights or the top or bottom half of the lights come on when the staircase is approached. Or the lights can be programmed to interact with the pedestrian one or two at a time. The video shows an abbreviated form of the system with just two lights. The video also shows an after-construction installation using half inch square chase for the wiring.
