Input unit arrangement
First Claim
1. An input unit arrangement with a mouse function mode and an input function mode, comprising:
- an image-recording device for recording images; and
a signal-processing device for processing the images to achieve the mouse function mode and the input function mode, wherein the input unit arrangement is arranged to switch from the input function mode to the mouse function mode when the signal-processing device detects a predetermined position-coding pattern in one of said images.

Abstract
In an input unit arrangement use is made of an input unit in combination with a mouse pad, which is provided with a position-coding pattern which codes coordinates for a plurality of positions on the mouse pad. Areas on the mouse pad are provided with subsets of the position-coding pattern which are dedicated to different functions. The input unit can be caused to optically read the position-coding pattern, whereupon the input unit arrangement decodes the positions that are coded locally on the mouse pad. By placing the input unit within the various areas on the mouse pad, a user can make the input unit arrangement carry out various functions, such as automatically switching from a mouse function, in which a cursor is controlled on a display on the basis of the decoded position, to an input function, in which information via the input unit is inputted into an electronic device, such as a computer, telephone, PDA etc. A method for controlling the input unit arrangement is also described, as is also use of an absolute position-coding pattern.

16. An input unit arrangement with at least a first and a second function, comprising:
-
an image-recording device for recording images and a signal-processing device for processing the images, wherein the input unit arrangement is arranged to switch from the first function to the second function when the signal-processing device detects a predetermined position-coding pattern in one of said images. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A method for providing for an input unit arrangement comprising:
-
providing for an input function mode and a mouse function mode in the input unit arrangement;
capturing a plurality of images;
processing the captured images;
determining that at least one of the captured images includes a predetermined position-coding pattern; and
switching from the input function mode to the mouse function mode based on the determination that at least one of the captured images includes the predetermined position-coding pattern. - View Dependent Claims (24)
