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, characterized in that 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 (300) in combination with a mouse pad (100), which is provided with a position-coding pattern which codes coordinates for a plurality of positions on the mouse pad (100). Areas (110-120) on the mouse pad (100) are provided with subsets of the position-coding pattern which are dedicated to different functions. The input unit (300) 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 (100). By placing the input unit (300) within the various areas (110-120) on the mouse pad (100), 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 (201) on the basis of the decoded position, to an input function, in which information via the input unit (300) is inputted into an electronic device (200), 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 a mouse 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, characterized in that the signal-processing device is arranged to detect part of an absolute position-coding pattern in one of said images, determine a position based on the detected part, and establish to which of at least two regions the position belongs, the input unit arrangement being arranged to carry out different functions depending on which region the signal-processing device establishes.
- 22. 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 (20, 210) for processing the images, characterized in that 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.
-
24. A mouse pad provided with a position-coding pattern, characterized in that the position-coding pattern on the mouse pad is divided into at least two regions which are intended to achieve different functions of an input unit arrangement.
-
30. Use of an absolute position-coding pattern in order to cause an input unit arrangement, preferably with a mouse function mode, to switch from a first to a second function.
- 31. A method for controlling an input unit arrangement between a first and a second function, the input unit arrangement comprising an image-recording device for recording images and a signal-processing device for processing the images, characterised in that the input unit arrangement automatically switches from the first function to the second function, when the signal-processing device detects a predetermined position-coding pattern in one of said images.
