Patent Number: 6,252,720

Title: Optical system and method for remotely manipulating interactive graphical elements on television screens and the like

Abstract: An optical virtual touch pad system wherein reflective optics are used to superimpose a virtual image of a television screen display onto a touch-sensitive digitizing surface being operatively contacted by a user-controlled contact member. Alternatively, the system uses reflective optics to superimpose an uninverted virtual image of the digitizing surface and the contact member operating thereon onto the surface of the display. The system thereby, for example, can be used as a user interface to control interactive content on a home television.
