Benefits of technology
"The present invention is an interactive display system that includes a display device, an image projector, computing means, and at least one remote signaling device. The remote signaling device is operable to transmit signals to the display device, which signals are stored by the computing means and used to control the image projected onto the display device. The system also includes a receiver portion on the display device, which receives signals from the remote signaling device and sends them to the computing means for display. The technical effects of this invention include improved control of the image projected onto the display device, increased efficiency of data transfer, and calibration of the image relative to the display device. Additionally, the system allows for wireless transmission of signals between the remote signaling device and the display device, and the use of multiple remote signaling devices."
Problems solved by technology
Problems arise with these existing interactive whiteboards in that it is difficult to assess a student's comprehension of the material.
Also, the systems require a cumbersome amount of wiring between the various parts of the system.

Embodiment Construction
[0039]Referring to FIG. 2, an interactive display system comprises a whiteboard 10 which communicates with a PC 12. A projector 14 receives signals from the PC 12 which are translated in to a corresponding projection image which is projected on to the whiteboard 10.
[0040]The image projected on to the whiteboard 10 is the same as that shown on a computer screen 28. By using an electronic pen 16, the position of which can be detected electronically by means of a plurality of wires embedded beneath the surface of the whiteboard 10, and using methods already known in the art, the electronic pen 16 can function in the same way as a computer mouse. Alternatively, the whiteboard may be of the resistive type, in which the presence of a pointing device is detected by pressure causing two layers to contact each other at a particular location, which location is then detected. A further alternative is the use of a laser pen. The position on the whiteboard of a light spot from the pen is calcula...

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.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 09 / 889,137, filed Jul. 12, 2001, which is the National Stage of International Application No. PCT / GB00 / 00012 filed Jan. 5, 2000, which claims the benefit of GB99 / 00555.5 filed on Jan. 13, 1999. Each of these applications and patents are incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION[0002]This invention relates to an interactive display system, particularly, but not limited to an interactive display system which includes a remote signaling device.[0003]Existing interactive displays make use of an electronic whiteboard which can sense the position of an electronic pen on the surface of the whiteboard. When a computer display is projected onto the whiteboard and its position calibrated, the electronic pen can be used in the same way as a computer mouse to manipulate objects on the computer display by passing the electronic pen over the surf...
