An interactive gaming device capable of perceiving user movement includes a controller connected to a display for providing user interaction with a game being played on the gaming device. The controller is further connected to a user input consisting of a light emitter and a light detector. The input may include a plurality of light emitters for emitting light at a plurality of locations and a single light detector for detecting light, or a single light emitter for emitting light, and a plurality of light detectors for detecting light at a plurality of locations, or a plurality of light emitters for emitting light at a plurality of locations, and a plurality of light detectors each being positioned in proximity to one of the plurality of light emitters for detecting light at a plurality of locations, or a game piece having a light emitter for emitting light, and a plurality of light detectors for detecting light at a plurality of locations. In each form, the controller polls the light detectors to see if user or game piece presence about that light emitter has caused the light emitted from the game piece to reflect to the polled light detector. If light has been reflected to the light detector, the controller is notified as such thereby allowing it to determine where the user is and where the user has moved.
