Abstract

A device for position determination. The device comprises a processing means for determining a position on a surface on the basis of an image of a position-coding pattern printed on the surface. The processing means is arranged to decode the position-coding pattern in the image, and to cause a writing means to write on the surface only in the event of the position-coding pattern being successfully decoded.

Claims

1. A device for position determination, comprising a processing means for determining a position on a surface on the basis of an image of a position-coding pattern printed on the surface, wherein the processing means is arranged to decode the position-coding pattern in the image, and to cause a writing means to write on the surface only in the event of said position-coding pattern being successfully decoded.

2. The device for position determination as claimed in claim 1, further comprising the writing means.

3. The device as claimed in claim 2, wherein the writing means comprises at least one nozzle that is arranged to dispense ink onto the surface.

4. The device as claimed in claim 1, further comprising an image sensor for recording said image of the position-coding pattern.

5. The device as claimed in claim 1, further comprising a transceiver for wireless transmission of data from the device to an external unit.

6. The device as claimed in claim 1, wherein the device is hand-held.

7. A method for position determination, comprising processing an image of a position-coding pattern on a surface, wherein the processing comprises decoding the position-coding pattern in the image, and causing a writing means to write on the surface only in the event of said position-coding pattern being successfully decoded.

8. The method as claimed in claim 7, further comprising writing on the surface by dispensing ink.

9. The method as claimed in claim 8, wherein said ink is dispensed onto said surface by means of at least one.

10. The method as claimed in claim 7, further comprising recording said image of the position-coding pattern.
