An interactive display is described wherein a rear projection screen is mounted above a base housing. Inside the housing is a touch position sensor to which a pedestal is mounted and extends through an opening in the housing to support the rear projection screen at a comfortable level. The touch position sensor produces touch signals indicative of where a person touched the rear projection screen. A projector responsive to video signals from a program storage device controlled by the touch signals is mounted inside the base housing and generates an optical beam which is directed via a reflector onto the rear of the projection screen.
