Abstract

A user interface in handheld devices has a touch screen for generating control signals for control of an electronic device, with a continuous touch movement detection on the touch area from a single touch from a begin sub-area to an end sub-area via a middle sub-area, in the touch control logic of the touch screen. The continuous touch movement detection in the logic memory creates substantially an arc touch movement from the begin sub-area to the end sub-area. The arc touch movement in the touch control logic of the touch screen is used to generate a control command signal for the electronic device. The touch movement detections, clockwise or anticlockwise, convex or concave are used to generate different control signals for the device and thus provide a large number of navigation control functions.

Claims

1. A system for using a touch screen for generating control signals for control of an electronic device, comprising:

a. a touch area of a touch screen that is partitioned into a grid of multiple touch sub-areas in a touch control logic of the touch screen;

b. a continuous touch movement detection from a single touch on the touch area from a begin sub-area to an end sub-area via a middle sub-area, the continuous touch movement detection in the touch control logic creates substantially an arc touch movement from the begin sub-area to the end sub-area;

c. the arc touch movement in the touch control logic of the touch screen is used to generate a control command signal for the electronic device.

2. The system as in claim 1, further comprising:

the continuous touch movement from the begin sub-area to the end sub-area via the middle sub-area, where the continuous touch movement creates substantially a ninety degree arc touch movement in the touch control logic.

3. The system as in claim 2, further comprising:

the continuous touch movement from the begin sub-area to the end sub-area via the middle sub-area, where the continuous touch movement creates substantially either a convex arc or a concave arc touch movement in the touch control logic.

4. The system as in claim 3, further comprising:

different touch movement detections either clockwise or anticlockwise and either convex or concave are used to generate different control signals for the device.

5. The method as in claim 1, further comprising:

a continuous touch movement detection from the begin sub-area to the end sub-area over multiple contiguous middle sub-areas, where the touch movement creates substantially a semi-circle touch movement in the touch control logic.

6. The system as in claim 5, further comprising:

different semi-circle touch movements, in the touch control logic, either clockwise or anti-clockwise and either convex or concave generate different control signals for the device.

7. The system as in claim 1, further comprising:

a continuous touch movement detection from the begin sub-area to the end sub-area over multiple contiguous middle sub-areas creates, where the touch movement creates substantially a closed figure touch movement in the touch control logic.

8. The system as in claim 7, further comprising:

different closed figure touch movements either clockwise or anticlockwise in the touch control logic generate different control signals for the device.

9. The system as in claim 1, further comprising:

the touch area is positioned on any part of the touch screen.

10. A method of using a touch screen for generating control signals for control of an electronic device, comprising the steps of:

a. partitioning a contiguous touch area in a touch control logic of the touch screen into a grid of multiple touch sub-areas;

b. detecting a continuous touch movement from a single touch on the touch area from a begin sub-area to an end sub-area via a middle sub-area, the continuous touch movement creating in the touch control logic substantially an arc touch movement from the begin sub-area to the end sub-area;

c. using the detected arc touch movement in the touch control logic of the touch screen for generating a control command signal for the device.

11. The method as in claim 10, further comprising the steps of:

detecting the continuous touch movement from the begin sub-area to the end sub-area via the middle sub-area, where the continuous touch movement creating a substantially ninety degree arc touch movement from the begin sub-area to the end sub-area.

12. The method as in claim 11, further comprising:

detecting the continuous touch movement from the begin sub-area to the end sub-area via the middle sub-area, the continuous touch movement creating substantially either a convex arc or a concave arc touch movement in the touch control logic.

13. The method as in claim 12, further comprising the steps of:

detecting different touch movement detections either clockwise or anticlockwise and either convex or concave are used to generate different control signals for the device.

14. The method as in claim 10, further comprising the steps of:

detecting a continuous touch movement from the begin sub-area to the end sub-area over multiple contiguous middle sub-areas, where the touch movement creates substantially a semi-circle touch movement in the touch control logic.

15. The method as in claim 14, further comprising the steps of:

detecting different semi-circle touch movements, in the touch control logic, either clockwise or anti-clockwise and either convex or concave generating different control signals for the device.

16. The method as in claim 10, further comprising the steps of:

detecting a continuous touch movement from the begin sub-area to the end sub-area over multiple contiguous middle sub-areas creating substantially a closed figure touch movement in the touch control logic.

17. The method as in claim 16, further comprising the steps of:

detecting different closed figure touch movements either clockwise or anticlockwise in the touch control logic, generating different control signals for the device.

18. The method as in claim 10, further comprising the steps of:

positioning the contiguous touch area on any part of the touch screen.

19. A system for using a touch screen for generating control signals for control of an electronic device, comprising:

a. a touch area of a touch screen that is partitioned into a grid of multiple touch sub-areas in a touch control logic of the touch screen;

b. a continuous touch movement detection from a single touch on the touch area from a begin sub-area to an end sub-area, where the continuous touch movement is over one of, (i) three contiguous sub-areas, (ii) four contiguous sub-areas, (iii) five contiguous sub-areas, and (iv) more than five contiguous sub-areas and where the continuous touch movement detection in the touch control logic creates a control command for the electronic device.

20. The system as in claim 19, further comprising:
