Abstract

A multi-touch pad control method is disclosed. The method comprises the following steps. First of all, a primary cursor is detected. Then a first touch motion is detected, if there is no first touch motion, primary cursor is re-detected. Next a secondary cursor is detected if there is a first touch motion. Then a second touch motion is detected. A first function is performed if there is no second touch motion. A first direction of the second touch motion is detected, if the second touch motion controlling the secondary cursor is detected. A second function is performed if the second touch motion is toward first direction. A second direction of the second touch motion is detected, if the second touch motion is not toward the first direction. A third function is performed if the second touch motion is toward the second direction, wherein the first function is performed if the second touch motion controlling the secondary cursor is detected and the second touch motion is neither toward the first direction nor the second direction.

Claims

1. A multi-touch pad control method, said method comprising:

detecting a primary cursor;

detecting a first touch motion on a touch pad;

re-detecting the primary cursor if there is no touch motion;

detecting a secondary cursor if there is a touch motion;

detecting a second touch motion on the touch pad;

performing a first function if there is no second touch motion detected;

detecting a first direction of the second touch motion if the second touch motion controlling the secondary cursor is detected.

performing a second function if the second touch motion is toward the first direction;

detecting a second direction of the second touch motion if the second touch motion is not toward the first direction; and

performing a third function if the second touch motion is toward the second direction, wherein the first function is performed if the second touch motion controlling the secondary cursor is detected and the second touch motion is neither toward the first direction nor the second direction.

2. The method according to claim 1, wherein the touch pad comprises a touch pad of a digital tablet.

3. The method according to claim 1, wherein the touch pad comprises a touch pad of a notebook/laptop personal computer.

4. The method according to claim 1, wherein the touch pad comprises a writing pad of a digital tablet.

5. The method according to claim 1, wherein the first function comprises moving a cursor.

6. The method according to claim 1, wherein the second function and the third function comprise a first button function and a second button function of a mouse respectively

7. A computer readable medium storing processor executable instructions operable to perform a multi-touch pad control method, said method comprising:

detecting a primary cursor;

detecting a first touch motion on a touch pad;

re-detecting the primary cursor if there is no touch motion;

detecting a secondary cursor if there is a touch motion;

detecting a second touch motion on the touch pad;

performing a first function if there is no second touch motion detected;

detecting a first direction of the second touch motion if the second touch motion controlling the secondary cursor is detected.

performing a second function if the second touch motion is toward the first direction;

detecting a second direction of the second touch motion if the second touch motion is not toward the first direction; and

performing a third function if the second touch motion is toward the second direction, wherein the first function is performed if the second touch motion controlling the secondary cursor is detected and the second touch motion is neither toward the first direction nor the second direction.

8. The method according to claim 7, wherein the touch pad comprises a writing pad of a digital tablet.

9. The method according to claim 7, wherein the first function comprises moving a cursor.

10. The method according to claim 7, wherein the second function and the third function comprise a first button function and a second button function of a mouse respectively
