Abstract

There is provided a method of controlling a computer system of an interactive display system, comprising: predetermining one or more positions on an interactive display of the interactive display system; displaying an image representing the predetermined one or more positions; receiving data identifying one or more detected positions selected on the interactive display; comparing the detected positions and the predetermined positions, wherein in dependence on a match the computer system registers the interactive display with the computer systems.

Claims

1. A method of establishing communication between a computer system and an interactive display, comprising:

storing, at said computer system a code corresponding to a sequence of positions on an interactive surface;

detecting, at said interactive surface, selection of a sequence of positions on said surface;

transmitting a code, from the interactive surface, corresponding to the sequence of detected positions;

comparing, at the computer, the stored codes and the transmitted code;

wherein in determination of a match, the interactive display is registered with the computer.

2. The method of claim 1 further comprising the steps of:

displaying a plurality of points on the interactive surface, wherein the points are displayed at the sequence of positions.

3. The method of claim 2 wherein the points are displayed with a sequence indicator, the step of detecting including detecting the sequence order, and the stored code further corresponding to an order of sequence positions.

4. The method of claim 3, further comprising in dependence on determination of a match, calibrating the interactive surface and the computer in dependence on the transmitted code and the stored code.

15. A computer program product for storing computer program code which, when executed on a computer system, performs the method of claim 1.

16. A computer program for execution on a computer system to perform the method of claim 1.

5. A method of establishing communication between an interactive display and a computer system, comprising:

detecting one or more inputs at the interactive display;

comparing the detected one or more inputs to a predetermined one or more inputs at the computer system; and

in dependence on a match, registering the interactive display and the computer system.

6. The method of claim 5 wherein the step of detecting one or more inputs at the interactive display includes detecting the position of the one or more inputs on the interactive display.

7. The method of claim 6 wherein, the step of detecting more than one input at the interactive display includes detecting the sequence of the inputs on the interactive display.

8. The method of claim 7 wherein data corresponding to the predetermined one or more inputs is used to generate a displayed image.

9. The method of claim 8 wherein the step of comparing comprises determining if the detected one or more positions of the detected one or more inputs correspond to one or more predetermined positions on the interactive display.

10. The method of claim 9 wherein the step of comparing comprises determining if a sequence of detected positions of more than one detected inputs correspond to a predetermined sequence of more than one predetermined position on the interactive display.

11. The method of claim 10 wherein in dependence on whether a predetermined sequence of positions or a predetermined sequence of areas is matched, the computer systems uses the detected inputs at the interactive display to calibrate the displayed image.

12. A method of controlling a computer system of an interactive display system, comprising:

predetermining one or more positions on an interactive display of the interactive display system;

displaying an image representing the predetermined one or more positions;

receiving data identifying one or more detected positions selected on the interactive display;

comparing the detected positions and the predetermined positions, wherein in dependence on a match the computer system registers the interactive display with the computer systems.

13. The method according to claim 12 wherein the step of predetermining comprises predetermining a plurality of positions, and predetermining a sequence of said plurality of positions, and the step of receiving comprises receiving data identifying a plurality of detected positions, and a sequence of said detected positions, wherein the comparing step further includes comparing said sequences.

14. The method of claim 13 wherein the step of displaying includes displaying the images on the interactive display, wherein responsive to a match the displayed image is calibrated in dependence upon the detected positions.

17. An interactive display system including a computer system and an interactive display, comprising:

a memory in said computer system for storing a code corresponding to a sequence of positions on an interactive surface;

a detector at said interactive surface of detecting selection of a sequence of positions on said surface;

a transmitter, at the interactive surface, for transmitting a code corresponding to the sequence of detected positions;

a comparator, at the computer system, for comparing stored codes with a code received from the transmitter of the interactive surface; and

a controller at the interactive display for completing registration with the computer and determination of a match.

18. An interactive display system including a computer system and an interactive display, comprising:

means for detecting one or more inputs at the interactive display;

means for comparing the detected one or more inputs to a predetermined one or more inputs'"'"'at the computer system; and

means for, in dependence on a match, registering the interactive display and the computer system.

19. A computer system of an interactive display system, comprising:

means for predetermining one or more positions on an interactive display of the interactive display system;

means for displaying an image representing the predetermined one or more positions;

means for receiving data identifying one or more detected positions selected on the interactive display; and

means for comparing the detected positions and the predetermined positions, wherein in dependence on a match the computer system registers the interactive display with the computer systems.

20. The computer system according to claim 19 wherein the means for predetermining comprises means for predetermining a plurality of positions, and predetermining a sequence of said plurality of positions, and the means for receiving comprises means for receiving data identifying a plurality of detected positions, and a sequence of said detected positions, wherein the means for comparing further includes means for comparing said sequences.
