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 display monitor provides a graphical representation in response to a pressure registered by the touch screen, wherein the graphical representation includes an attribute that depends on a magnitude of the pressure registered by the touch screen, and wherein the graphical representation is rendered as centered around a first area on the display monitor below a second area on the touch screen at which the pressure is exerted, wherein the attribute does not change until the magnitude of the pressure exceeds a predetermined threshold pressure value, and wherein the attribute changes in proportion to the magnitude of the pressure when the magnitude exceeds the predetermined threshold pressure value.

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 attribute comprises at least one of:

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

4. The system of claim 1, wherein the attribute has a property that is programmable.

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

6. The system of claim 1, wherein the predetermined threshold pressure value is user-programmable.

7. Control software stored in a memory and executed by a data processing system with a pressure-sensitive touch screen arranged over a display monitor, the software being operative to have the display monitor provide a graphical representation in response to a pressure registered by the touch screen, the graphical representation including an attribute that depends on a magnitude of a pressure registered by the touch screen and to have the graphical representation rendered as centered around a first area on the display monitor below a second area on the touch screen at which the pressure is exerted, wherein the attribute does not change until the magnitude of the pressure exceeds a predetermined threshold pressure value, and wherein the attribute changes in proportion to the magnitude of the pressure when the magnitude exceeds the predetermined threshold pressure value.

8. The software of claim 7, operative to control the rendering of the graphical representation that has an attribute depending on a magnitude of the pressure, wherein the attribute comprises at least one of a size, a shape, a color, contrast with an image rendered on the display monitor, and transparency.

9. The software of claim 7, wherein the predetermined threshold pressure value is user-programmable.

10. A pressure-sensitive touch screen arranged over a display monitor, wherein the display monitor is configured to provide a graphical representation in response to a pressure registered by the touch screen, the graphical representation including attribute that depends on a magnitude of a pressure registered by the touch screen, and wherein the graphical rerepresentation is rendered as centered around a first area on the display monitor below a second area on the touch screen at which the pressure is exerted, wherein the attribute does not change until the magnitude of the pressure exceeds a predetermined threshold pressure value, and wherein the attribute changes in proportion to the magnitude of the pressure when the magnitude exceeds the predetermined threshold pressure value.

11. The screen of claim 10, wherein the predetermined threshold pressure value is user-programmable.

12. 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 on the display monitor a graphical representation in response to a pressure registered by the touch screen, the graphical representation with an attribute that depends on a magnitude of a pressure registered by the touch screen, wherein the graphical representation is rendered as centered around a first area on the display monitor below a second area on the touch screen at which the pressure is exerted, wherein the attribute does not change until the magnitude of the pressure exceeds a predetermined threshold pressure value, and wherein the attribute changes in proportion to the magnitude of the pressure when the magnitude exceeds the predetermined threshold pressure value.

13. The method of claim 12, comprising controlling a first dimension of the first area in dependence of a second dimension of the second area.

14. 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.

15. The method of claim 12, wherein the predetermined threshold pressure value is user-programmable.
