Abstract

A touch control input system and a signal generation method are provided. The touch control input system includes a touch control interface, a sensor unit, and a control unit. The touch control input system is featured by sectioning a plurality of blocks based on a plurality of grid lines for constructing the touch control interface so as to identify the displace movement of an external operator based on the blocks. The sensor unit functions to detect changes of logic states of the blocks. Accordingly, the control unit is able to identify the displace movement from one grid line to the other grid line through the detected changes of logic states, which in turn can be utilized to generate a displacement data for controlling electronic apparatuses.

Claims

1. A touch control input system for use in an electronic apparatus, applied to generate a displacement data for controlling the electronic apparatus, the touch control input system comprising:

a touch control interface having a plurality of blocks sectioned by a plurality of grid lines, for an operator performing a displace movement;

at least one sensor unit, coupled to the touch control interface, for sensing changes of logic states of the blocks; and

a control unit, coupled to the sensor unit, for determining the displace movement from a first grid line to a second grid line of the grid lines based on the changes of logic states so as to generate a displacement data.

2. The touch control input system of claim 1, wherein the displacement data comprises a first position signal and a second position signal.

3. The touch control input system of claim 2, wherein the control unit generates the first position signal when the external operator is performing the displace movement at the first grid line.

4. The touch control input system of claim 3, wherein the control unit generates the second position signal when the external operator is performing the displace movement at the second grid line.

5. The touch control input system of claim 1, wherein the control unit determines that the displace movement is positioned at the first grid line when the changes of logic states are corresponding to two adjacent blocks bordering the first grid line.

6. The touch control input system of claim 1, wherein the electronic apparatus is a portable electronic apparatus such as a multimedia playback, a mobile phone, a notebook computer, or a personal digital assistant (PDA).

7. A signal generation method for use in a touch control input system of an electronic apparatus, the signal generation method comprising:

providing a touch control interface having a plurality of grid lines and a plurality of blocks sectioned by the grid lines;

performing a displace movement by an operator on the touch control interface;

generating changes of logic states corresponding to the plurality of blocks based on the displace movement; and

determining the displace movement from a first grid line to a second grid line of the grid lines by a control unit for generating a displacement data based on the changes of logic states.

8. The signal generation method of claim 7, wherein the displacement data comprises a first position signal and a second position signal.

9. The signal generation method of claim 8, wherein the control unit generates the first position signal when the external operator is performing the displace movement at the first grid line.

10. The signal generation method of claim 9, wherein the control unit generates the second position signal when the external operator is performing the displace movement at the second grid line.

11. The signal generation method of claim 7, wherein the control unit determines that the displace movement is positioned at the first grid line when the changes of logic states are corresponding to two adjacent blocks bordering the first grid line.

12. The signal generation method of claim 7, wherein the electronic apparatus is a portable electronic apparatus such as a multimedia playback, a mobile phone, a notebook computer, or a personal digital assistant (PDA).
