Abstract

A remote control device has a display monitor for rendering an image and a touch screen for user interaction. The touch screen is pressure-sensitive. The device has an operational mode wherein the image is being scaled dependent on a value of the pressure registered by the touch screen.

Claims

1-7. -7. (canceled)

8. A data processing system with a display monitor for rendering an image and a touch screen for user interaction with the system, wherein:

the touch screen is pressure-sensitive;

the system has an operational mode wherein a scale of the image is dependent on a value of a pressure registered by the touch screen and wherein the scale of the image is conditionally retained after a decrease of the value of the pressure.

9. The system of claim 8 operative to retain the scale of the image upon a pre-determined user interaction with the touch screen.

10. The system of claim 8 operative to change back the scale of the image upon a pre-determined user interaction with the touch screen.

11. The system of claim 9, wherein the predetermined user interaction comprises at least one of:

applying the pressure having the value above a threshold;

increasing the pressure at a rate higher than a further threshold.

12. The system of claim 8, accommodated in at least one of:

a remote control device, a cell phone;

a handheld PC, a laptop PC.

13. Method of enabling user interaction with a data processing system that comprises a display monitor for rendering an image, and a pressure-sensitive touch screen for the user interaction, wherein the method comprises changing a scale of the image dependent on a value of the pressure registered by the touch screen and conditionally retaining the scale of the image after a decrease of the value of the pressure.

14. The method of claim 13 comprising retaining the scale of the image upon a pre-determined user interaction with the touch screen.

15. The method of claim 13 comprising changing back the scale of the image upon a pre-determined user interaction with the touch screen.

16. The method of claim 15, wherein the predetermined user interaction comprises at least one of:

the user applying the pressure having the value above a threshold;

the user increasing the pressure at a rate higher than a further threshold.

17. Control software for use with a data processing system that has a display monitor for rendering an image and a pressure-sensitive touch screen for user interaction with the system, the software being operative to change a scale of the image dependent on a value of the pressure registered by the touch screen and to conditionally retain the scale after a decrease of the value of the pressure.

18. The software of claim 17, operative to retain the scale of the image upon a pre-determined user interaction with the touch screen.

19. The software of claim 17, operative to change back the scale of the image upon a pre-determined user interaction with the touch screen.

20. The software of claim 19, wherein the predetermined user interaction comprises at least one of:

applying the pressure having the value above a threshold;

increasing the pressure at a rate higher than a further threshold.
