Abstract

The invention relates to a user interaction arrangement for interaction with a user using a pointing object. The arrangement comprises: a detector for detecting position of said object, a controller for computing a distance of said object to a surface of a display, and an image generating part for generating an image on said surface of display. The controller is further configured to compute a position on said surface based on said position and distance of said object, and the arrangement further comprises an image generating part configured to generate a dynamic guiding image on said surface of display based on said position and distance.

Claims

1. A user interaction arrangement for interaction with a user using a pointing object, said arrangement comprising:

a detector for detecting a position of said object,

a controller for computing a distance of said object to a surface of a display,

an image generating part for generating an image on said surface of display;

said controller being further configured to compute a position on said surface based on said distance of the object and the image generating part being further configured to generate a dynamic guiding image with respect to said position and distance, said dynamic guiding image having variable characteristic depending on said distance on said surface of display.

2. The arrangement of claim 1, wherein said characteristic is one or several of shape, size, color or contrast.

3. The arrangement of claim 1, wherein said dynamic guiding image changes shape, size, color or contrast when the distance reduces.

4. The arrangement according to claim 1, comprising a capacitive electric field generator and receiver.

5. The arrangement according to claim 1, for use in a mobile terminal having a touch sensitive display.

6. The arrangement according to claim 1, wherein said dynamic guiding image has an appearance deviating from an image reproduced on the display.

7. The arrangement according to claim 1, wherein said dynamic guiding image is a cross-hair.

8. An electric device comprising a display, a communication portion and a user interaction arrangement comprising:

at least one transmitter for generating a signal, the arrangement being configured to detect a pointing object for interaction with said device, a controller for computing a distance of said object to said display, an image generating part for generating an image on said display, the controller being further configured to compute a position on said surface based on said distance of the object and the image generating part being further configured to generate a dynamic guiding image with respect to said position and distance, said dynamic guiding image having variable characteristic depending on said distance on said surface of display.

9. The device of claim 8, being one of a mobile communication terminal, a camera, a global positioning system (GPS) receiver;

a personal communications system (PCS) terminal, a personal digital assistant (PDA);

a personal computer, a home entertainment system or a television screen.

10. The device of claim 8, wherein said object is a finger or stylus.

11. The device of claim 8, wherein said interaction is information input into said device.

12. The device of claim 8, wherein said image generator further generates a keyboard.
