Method for controlling a mouse pointer by touch pad

A method for controlling a mouse pointer by a touch pad, the method comprises the following steps:

• step (S10), detecting a first touch signal using the touch pad;
• step (S11), judging whether the first touch signal is detected;
• step (S12), activating a dynamic unlocking area surrounding a first position where the first touch signal is detected, and mouse pointer is controllable by a movement of the first touch signal in the dynamic unlocking area;
• step (S13), detecting the movement of the first touch signal, and the dynamic unlocking area moves with the movement of the first touch signal;
• step (S14), judging whether the first touch signal disappears;
• step (S15), activating a click unlocking area, in the dynamic unlocking area, and surrounding a second position where the first touch signal disappears;
• step (S16), detecting a second touch signal, judging whether the second touch signal is detected within a time threshold;
• step (S17), judging whether the second touch signal is in the dynamic unlocking area;
• step (S18), judging whether the second touch point is in the click unlocking area;
• and
• step (S19), perform click function and then go to step (S12);
• wherein:
• in step (S11), if yes go to step (S12), and if no, go to step (S10);
• in step (S14), if yes, go to step (S15), and if no, go to step (S13);
• in step (S16), if yes, go to step (S17), and if no, go to step (S10);
• in step (S17), if yes, go to step (S18), and if no, go to step (S16);
• and
• in step (S18), if yes, go to step (S19), if no, go to step (S12).
