[Stairway to Diet] is a motion sensor interactive installation. The idea behind this installation is to promote the two most prominent goals in recent years: fitness and sustainability. This device not only encourages elevator users to take the stairs as an alternative to taking the elevators, it also has the effect of energy conservation if the elevator users actually forfeit the elevator.

• The interaction starts when elevator users approach the elevator where the device is located. When the device detects motion in close proximity, the LED lights of the device starts going off. The person(s) in the close proximity of the device will inevitably notice the LED lights and the message encrypted on the device. The device in turn reminds the elevator users the option of taking the stairs and its positive effect, namely fitness.
