INTERACTIVE DISPLAY SYSTEM
First Claim
1. An interactive display system comprising:
- a projector;
a device onto which an image is projected from the projector;
a computing means;
a pointing device; and
a plurality of remote signaling devices, in which system;
the computing means is arranged to supply image information to the device onto which an image is projected from the projector;
the plurality of remote signaling devices are operable to transmit signals;
the device onto which an image is projected from the projector includes position indication means for determining the position of the pointing device relative to a surface of the device onto which an image is projected from the projector;
the pointing device is operable to;
take precedence over the remote signaling devices; and
selectively enable each remote signaling device.

Abstract
An interactive display system comprises a white board which communicates with a PC. A projector receives signals from the PC which are translated into corresponding project image which is projected on to the white board. The image projected on to the white board is the same as that shown on a computer screen. By using an electronic pen the position of which can be detected electronically by means of a plurality of wires embedded beneath the surface of the white board and using methods already known in the art, the electronic pen can function in the same way as a computer mouse. The image projected on to the white board may also be manipulated by means of a remote control device, which uses Infra red communication to transmit signals to a transponder built within the white board.
