Abstract

An input device and a control method thereof are described. The input device includes an optical trace-detecting module, an instruction determining module, and an instruction code transmitting module. A finger moving signal is received by the optical trace-detecting module, an input rotating instruction is judged according to the finger moving signal, and then a rotating instruction code corresponding to an angle is transmitted.

Claims

1. An input device, comprising:

an optical trace-detecting module, for receiving a plurality of finger moving signals finger moving signal;

an instruction determining module, for judging whether to transmit a rotating instruction or not according to the finger moving signal; and

an instruction code transmitting module, for transmitting an instruction code corresponding to the rotating instruction to a computer,

wherein the instruction determining module determines whether to trigger the rotating instruction or not according to a variation which relates to a sequence of the finger moving signals between X axis and Y axis in positive and negative directions.

2. The input device according to claim 1, further comprising:

a recording module, for recording a finger touch area of a finger on the optical trace-detecting module in a time period, wherein the finger touch area is any one of several areas divided on the optical trace-detecting module.

3. The input device according to claim 2, wherein the instruction determining module judges that the rotating instruction is a right rotating instruction according to continuous signals of touching top, right, bottom, and left areas of the optical trace-detecting module in sequence by the finger.

4. The input device according to claim 2, wherein the instruction determining module judges that the rotating instruction is a left rotating instruction according to continuous signals of touching top, left, bottom, and right areas of the optical trace-detecting module in sequence by the finger.

5. A control method of an input device, comprising:

obtaining a finger moving signals by using an optical trace-detecting module;

judging whether to transmit a rotating instruction or not according to the finger moving signal; and

transmitting an instruction code corresponding to the rotating instruction to a computer,

wherein judging whether to trigger the rotating instruction or not according to a variation which relates to a sequence of the finger moving signals between X axis and Y axis in positive and negative directions.

6. The control method of an input device according to claim 5, further comprising:

a recording module, for recording a finger touch area of a finger on the optical trace-detecting module in a time period, wherein the finger touch area is any one of several areas divided on the optical trace-detecting module.

7. The control method of an input device according to claim 5, wherein the instruction determining module judges that the rotating instruction is a right rotating instruction according to continuous signals of touching top, right, bottom, and left areas of the optical trace-detecting module in sequence by the finger.

8. The control method of an input device according to claim 5, wherein the instruction determining module judges that the rotating instruction is a left rotating instruction according to continuous signals of touching top, left, bottom, and right areas of the optical trace-detecting module in sequence by the finger.

10. The control method of an input device according to claim 5, further comprising:

a recording module, for recording a finger touch area of a finger on the optical trace-detecting module in a time period, wherein the finger touch area is any one of several areas divided on the optical trace-detecting module.

11. The control method of an input device according to claim 5, wherein the instruction determining module judges that the combination instruction according to continuous signals of touching different areas of the optical trace-detecting module in sequence by the finger.

9. A control method of an input device, comprising:

obtaining a finger moving signals by using an optical trace-detecting module;

judging whether to transmit a combination instruction or not according to the finger moving signal; and

transmitting an instruction code corresponding to the combination instruction to a computer,

wherein judging whether to trigger the rotating instruction or not according to a variation which relates to a sequence of the finger moving signals between X axis and Y axis in positive and negative directions.
