Abstract: An interactive window display enables a person to activate one or more electrical devices located inside an enclosure from outside of the enclosure. Each electrical device is electrically connected to an infrared sensor located inside the enclosure. Each infrared sensor emits a light beam through a window of the enclosure. A person on the outside of the enclosure can manually place a small reflective card against the window in the path of the light beam of a selected infrared sensor. The light beam is reflected back to the infrared sensor. Upon sensing the reflected light beam, the infrared sensor produces a signal that energizes an electrical circuit and activates the associated electrical device.
