Input unit arrangement
First Claim
1. An input unit arrangement for controlling an electronic device, comprising:
- a base;
a position-coding pattern printed on said base and coding a first and second sets of absolute positions on spatially separate areas of said base;
said first and second sets of absolute positions being mutually exclusive and coded by spatially separate first and second subsets of said position-coding pattern;
a handheld image-recording device comprising an image sensor for recording images of said position-coding pattern; and
a processor for deriving at least one position from the position coding pattern in the recorded image, said processor providing an instruction to the electronic device to perform a first function when said at least one absolute position belongs to the first set, and a second function when said at least one absolute position belongs to the second set.

Abstract
An input unit arrangement for controlling an electronic device is provided. The arrangement comprises; a base; a position-coding pattern provided on the base and coding a first and second sets of absolute positions on spatially separate areas of the base, the first and second sets of absolute positions being mutually exclusive and coded by spatially separate first and second subsets of the position-coding pattern; a handheld image-recording device for recording images of the position-coding pattern; and a processor for deriving a position from the position coding pattern in the recorded image, the processor providing an instruction to the electronic device to perform a first function when the absolute position belongs to the first set, and a second function when the absolute position belongs to the second set. The arrangement enables a user to select different functions by selecting differing areas of the base on which the position-coding pattern is provided.

9. An interactive substrate for use in an input arrangement having an optical sensor reading a position-coding pattern and providing a signal to an electronic device to provide instruction thereto, said substrate comprising:
-
a base; a position-coding pattern printed on said base and coding a first and second sets of absolute positions on spatially separate areas of said base, said first and second sets of absolute positions being mutually exclusive and coded by spatially separate first and second subsets of said position-coding pattern; said first and second subsets of absolute positions being associated with first and second functions of said electronic device to perform the function selected by use of the input sensor. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for controlling an electronic device between a first and a second function, using a handheld image recording device interacting with a position-code pattern comprising:
-
operating the handheld image-recording device having an optical sensor for recording images of the position-coding pattern printed on a base, the position coding pattern coding a first and second sets of absolute positions on spatially separate areas of the base;
said first and second sets of absolute positions being mutually exclusive and coded by spatially separate first and second subsets of said position-coding pattern, andoperating a processor for processing the images to derive at least one position from the position coding pattern in the recorded image, providing an instruction to the electronic device to perform a first function when said at least one absolute position belongs to the first set, and a second function when said at least one absolute position belongs to the second set. - View Dependent Claims (16, 17, 18, 19, 20)
