Abstract

A touch input system, comprising a surface, adapted to receive at least one simultaneous touch inputs from human fingers; a sensor adapted to detect the at least one touch inputs and produce at least one signal representing a unique position for the at least one touch input; and a processor, adapted to receive the at least one signal and produce an output representing a touch detection and a mapping of a coordinate position on the surface for each of the simultaneous touch inputs. The system may detect, for example, two touch inputs simultaneously. The surface may be non-planar and distinct from a small solid angle section of a sphere.

Claims (36)

1. A touch input system, comprising:

a surface which is neither planar nor a small solid angle section of a sphere, adapted to receive a touch input;

a sensor adapted to detect a touch and produce at least one signal representing a unique position of the touch input on the surface; and

a processor, adapted to receive the at least one signal and produce an output representing a touch detection and a mapping of a coordinate position on the surface;

wherein the sensor is configured to detect a simultaneous touch at each of a plurality of positions anywhere on the surface, and wherein the processor is adapted to produce an output representing a mapping of a coordinate position on the surface for each of the simultaneous touches.

2. The touch input system according to claim 1 , wherein the control further determines an intensity of a touch.

3. The touch input system according to claim 1 , wherein the control further determines a size of a contact area of a touch.

4. The touch input system according to claim 1 , wherein the control further analyzes a timing of changes in the signal output during a touch.

5. The touch input system according to claim 1 , wherein the substrate is light transmissive.

6. The touch input system according to claim 1 , wherein the control further determines an intensity of each of the plurality of simultaneous touches.

7. The touch input system according to claim 1 , wherein the control further determines a size of a contact area for each of the plurality of simultaneous touches.

8. The touch input system according to claim 1 , wherein the control further analyzes a timing of changes in the output over a course of the plurality of simultaneous touches.

9. The touch input system according to claim 1 , wherein an image is transmitted through the substrate.

10. A touch input method, comprising:

providing a surface configured to receive a plurality of simultaneous touch inputs at multiple positions anywhere on the surface;

sensing said plurality of simultaneous touch inputs and producing at least one signal representing a unique position of each touch input on the surface; and

receiving the at least one signal and producing an output representing a touch detection and a mapping of a coordinate position on the surface for each of the simultaneous touch inputs.

11. The method according to claim 10 , further comprising determining at least one of an intensity of a touch, a size of a contact area, and a timing of changes in an output of the electronic sensor during a touch.

12. The method according to claim 10 , wherein the surface is neither planar nor a small solid angle section of a sphere.

13. The method according to claim 10 , further comprising determining an intensity of each of the plurality of simultaneous touches.

14. The method according to claim 10 , further comprising determining a size of a contact area for each of the plurality of simultaneous touches.

15. The method according to claim 10 , further comprising analyzing a timing of changes in the output over a course of the plurality of simultaneous touches.

16. The method according to claim 10 , wherein the substrate is light transmissive.

17. The method according to claim 10 , further comprising:

processing the at least one signal in a manner adapted to maintain a distinction between the plurality of simultaneous touches;

determining a respective difference of at least one coordinate between the plurality of simultaneous touches; and

selectively producing the output at least in dependence on a relationship of the coordinates of the at least two simultaneous touches.

18. A touch input system, comprising:

a surface, configured to receive a plurality of simultaneous touch inputs from human fingers anywhere on the surface;

a sensor adapted to detect a plurality of simultaneous touch inputs and produce signals representing a unique position for each of the simultaneous touch inputs on the surface;

a processor, adapted to receive the signals and produce an output representing a touch detection and a mapping of a coordinate position on the surface for each of the plurality of simultaneous touch inputs.

19. The touch input system according to claim 18 , wherein the surface is non-planar.

20. The touch input system according to claim 18 , wherein the processor further determines at least one of an intensity of each touch, a size of a contact area of each touch, and a timing of changes in the output signals produced by the sensor during each touch.

21. The touch input system according to claim 20 , wherein the processor determines the intensity of each touch.

22. The touch input system according to claim 20 , wherein the processor determines the size of the contact area of each touch.

23. The touch input system according to claim 20 , wherein the processor further analyzes a timing of changes in the output signals during a touch.
