Abstract: The present disclosure describes an interactive display system, method and computer readable medium. In one embodiment, an interactive display surface having one or more computer generated patterns printed thereon may be utilized in conjunction with an electronic pen in order to identify the absolute position of the pen relative to the interactive display surface. In one embodiment, the absolute position of the electronic pen may be transmitted to a computer system and utilized to control one or more programs running on the computer system. In one embodiment, the visual output of the computer system may be superimposed upon the interactive display surface using one or more projectors. The computer generated patterns may have a predefined association with a control operation of the computer system such that placing the electronic pen in proximity to the associated generated pattern causes the computer system to execute the associated control operation.

Abstract: An interactive display system comprising a position coded pattern that is printed on a display surface. An electronic pen is equipped with a decoding real-time processor; the decoding of the surface pattern reveal sets of predetermined (x, y) coordinates embedded within the pattern. A real-time processor works simultaneously to decode (x, y) coordinates while these are sent immediately via wireless communication to a host PC which is normally attached to a projecting device.
