Abstract

There is disclosed an interactive display system comprising an interactive surface for displaying an image and for receiving inputs from remote devices, the system being adapted to detect the presence of at least two remote devices proximate the interactive surface.

Claims

1. An interactive system comprising an interactive surface for displaying an image and adapted for determining the position, in use, of a plurality of pointing devices on the interactive surface, the system being adapted to manipulate an image displayed on the interactive surface in dependence on the plurality of pointing devices, wherein separate images are joined responsive to detection of a first pointing device positioned on a first displayed image, and detection of a second pointing device positioned on a second displayed image, the joining being determined in dependence on detected movement of either or both of the first or second images such that the images are positioned within a predetermined distance of each other.

2. An interactive system according to claim 1 wherein said joining creates a single image.

3. An interactive system according to claim 1 wherein said joining creates a connection between the two images.

4. The interactive system of claim 1 comprising a drive grid signal generator for driving a drive grid for a Period of time at each of a plurality of frequencies associated with each of the plurality of pointing devices, wherein the system adapts the period of time for a given frequency to optimize said period of time for particular devices.

5. A method in an interactive system comprising an interactive surface for displaying an image and for detecting a position of a plurality of pointing devices, in use, on the interactive surface, wherein separate images are joined responsive to detection of a first remote device positioned on a first displayed image, and detection of a second remote device positioned on a second displayed image, the joining being determined in dependence on detected movement of either or both of the first or second images such that the images are positioned within a predetermined distance of each other.

6. The method according to claim 5 wherein said joining creates a single image.

7. The method according to claim 5 wherein said joining creates a connection between the two images.

8. The method of claim 5 comprising driving a drive grid for a period of time at each of a plurality of frequencies associated with each of the plurality of pointing devices, and adapting the period of time for a given frequency to optimize said period of time for particular devices.
