Abstract

A data processing system, e.g., a remote control device, has a pressure-sensitive touch screen arranged over a display monitor. The monitor provides a visual indication depending on a magnitude of a pressure registered by the touch screen. The indication is rendered as centered on the touch area and has an attribute that depends on the pressure exerted.

Claims

1. A data processing system with a pressure-sensitive touch screen arranged over a display monitor wherein the monitor provides a visual indication depending on a magnitude of a pressure registered by the touch screen and wherein the indication is rendered as centered around a first area on the monitor below a second area on the screen at which the pressure is exerted.

2. The system of claim 1, wherein the first area has a first dimension that is under control of a second dimension of the second area.

3. The system of claim 1, wherein the indication comprises a graphical representation with an attribute that depends on a magnitude of the pressure.

4. The system of claim 3, wherein the attribute comprises at least one of:

a size, a shape, a color, contrast with an image rendered on the display, and transparency.

5. The system of claim 3, wherein the attribute has a property that is programmable.

6. The system of claim 1 accommodated in a handheld electronic device.

7. Control software for use in a data processing system with a pressure-sensitive touch screen arranged over a display monitor, the software being operative to have the monitor provide a visual indication depending on a magnitude of a pressure registered by the touch screen and to have the indication rendered as centered around a first area on the monitor below a second area on the screen at which the pressure is exerted.

8. The software of claim 7, operative to control the rendering of the indication with a graphical representation that has an attribute depending on a magnitude of the pressure.

9. A pressure-sensitive touch screen arranged over a display monitor, wherein the monitor is configured to provide a visual indication depending on a magnitude of a pressure registered by the touch screen and wherein the indication is rendered as centered around a first area on the monitor below a second area on the screen at which the pressure is exerted.

10. A method of facilitating user interaction with a data processing system having a pressure-sensitive touch screen arranged over a display monitor, the method comprising providing a visual indication on the monitor depending on a magnitude of a pressure registered by the touch screen, wherein the indication is rendered as centered around a first area on the monitor below a second area on the screen at which the pressure is exerted.

11. The method of claim 10, comprising controlling a first dimension of the first area in dependence of a second dimension of the second area.

12. The method of claim 10, wherein the indication comprises a graphical representation with an attribute that depends on a magnitude of the pressure.

13. The method of claim 12, wherein the attribute comprises at least one of:

a size, a shape, a color, contrast with an image rendered on the display, and transparency.

14. The method of claim 12, wherein the attribute has a property that is user- programmable.
