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 begin cell to an end cell via a middle cell, in the logic memory of the touch screen. The continuous touch movement detection in the logic memory creates substantially an arc touch movement from the begin cell to the end cell. The arc touch movement in the logic memory of the touch screen is used to generate a control command signal for the electronic device. The continuous touch movement creates substantially a ninety degree arc, or a semi-circle, or closed figure touch movement in the logic memory. 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 cells in a control logic memory of the touch screen;

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

c. the arc touch movement in the logic memory 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 cell to the end cell via the middle cell, where the continuous touch movement creates substantially a ninety degree arc touch movement in the logic memory.

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

the continuous touch movement from the begin cell to the end cell via the middle cell, where the continuous touch movement creates substantially either a convex arc or a concave arc touch movement in the logic memory.

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 cell to the end cell over multiple contiguous middle cells, where the touch movement creates substantially a semi-circle touch movement in the logic memory.

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

different semi-circle touch movements, in the logic memory, 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 cell to the end cell over multiple contiguous middle cells creates, where the touch movement creates substantially a closed figure touch movement in the logic memory.

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

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

9. 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 control logic memory of the touch screen into a grid of multiple touch cells;

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

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

10. The method as in claim 9, further comprising the steps of:

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

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

detecting the continuous touch movement from the begin cell to the end cell via the middle cell, the continuous touch movement creating substantially either a convex arc or a concave arc touch movement in the logic memory.

12. The method as in claim 11, 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.

13. The method as in claim 9, further comprising the steps of:

detecting a continuous touch movement from the begin cell to the end cell over multiple contiguous middle cells, where the touch movement creates substantially a semi-circle touch movement in the logic memory.

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

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

15. The method as in claim 9, further comprising the steps of:

detecting a continuous touch movement from the begin cell to the end cell over multiple contiguous middle cells creating substantially a closed figure touch movement in the logic memory.

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

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

17. The method as in claim 9, further comprising the steps of:

composing the grid with at least nine such cells.

18. The method as in claim 9, further comprising the steps of:

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