- a housing having an optical opening, with said touch position sensor being mounted to said housing;
projection means, mounted to the housing, and responsive to the video signals for producing an optical beam representative of the video signals, with the optical beam directed to extend upwardly through the optical opening in the housing;
a pedestal mounted on the touch position sensor and extending upwardly therefrom;
a rear projection screen having a rear and front surface;
said rear projection screen being mounted on the pedestal with said rear surface thereof in the path of said upwardly directed optical beam emanating from the housing opening, and with the pedestal height selected to enable a person to touch said front surface to cause the generation of said touch signals from the touch position sensor.

Abstract
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.
