Abstract

A computer input device and a method for controlling a direction of an operated target using the same are described. The computer input device includes an optical touch control module, a motion look-up table, and look-up corresponding motion. The motion look-up table records a user'"'"'s operations made on the optical touch control module and corresponding motions performed accordingly. The motion look-up is executed to record a finger touch area where a finger touches the optical touch control module within a certain time period, to look up the motion look-up table for the corresponding motion to be performed according to the finger touch area and the record about a previous touch area, and to perform the corresponding motion to control the direction of the operated target.

Claims

1. A computer input device, suitable for controlling a direction of an operated target in application software, comprising:

an optical touch control module, having a light source, a sensor, and a light pervious element disposed toward the light source and the sensor;

a motion look-up table, for recording operations of a user at the optical touch control module and corresponding motions performed accordingly; and

a corresponding motion look-up means, for controlling the direction of the operated target according to a finger touch motion received by the optical touch control module, wherein the corresponding motion look-up means further comprises;

recording a finger touch area where a finger touches the optical touch control module within a certain time period;

looking up the motion look-up table for the corresponding motion to be performed according to the finger touch area and a record about a previous touch area; and

performing the corresponding motion to control the direction of the operated target.

2. The computer input device according to claim 1, wherein the corresponding motion is one selected from a group consisting of rotating leftward by 90 degrees, rotating rightward by 90 degrees, and rotating by 180 degrees.

3. The computer input device according to claim 1, wherein the finger touch area is any one of several areas divided on the touch module.

4. The computer input device according to claim 1, wherein a firmware further initializes the previous touch area into any one of the several areas divided on the touch module.

5. The computer input device according to claim 1, wherein the firmware further analyzes the corresponding motion by utilizing the motion look-up table, and then stores the current finger touch area as the previous touch area.

6. The computer input device according to claim 1, wherein the firmware further determines the corresponding motion to be performed according to a depicted curve of the finger touch motion.

7. The computer input device according to claim 6, wherein relations between the curve and the corresponding motion are listed as follows:

when the curve is a clockwise 90-degree curve, the motion is to rotate rightward by 90 degrees;

when the curve is an anticlockwise 90-degree curve, the motion is to rotate leftward by 90 degrees;

when the curve is a clockwise 180-degree curve, the motion is to rotate by 180 degrees; and

when the curve is an anticlockwise 180-degree curve, the motion is to rotate by 180 degrees.

8. A method for controlling a direction of an operated target through using a computer input device, wherein the computer input device is used to control the direction of the operated target in application software, the method comprising:

detecting a finger touch motion received by an optical touch control module of the computer input device;

obtaining a finger touch area where a finger touches the optical touch control module;

analyzing the corresponding motion to be performed through utilizing a motion look-up table according to the finger touch area and a previous touch area; and

performing the corresponding motion to control the direction of the operated target.

9. The method for controlling a direction of an operated target through using a computer input device according to claim 8, wherein the corresponding motion is one selected from a group consisting of rotating leftward by 90 degrees, rotating rightward by 90 degrees, and rotating by 180 degrees.

10. The method for controlling a direction of an operated target through using a computer input device according to claim 8, wherein the finger touch area is any one of several areas divided on the touch module.

11. The method for controlling a direction of an operated target through using a computer input device according to claim 8, wherein a firmware further initializes the previous touch area into any one of the areas divided on the touch module.

12. The method for controlling a direction of an operated target through using a computer input device according to claim 8, wherein the firmware further analyzes the corresponding motion by utilizing the motion look-up table, and then stores the current finger touch area as the previous touch area.

13. The method for controlling a direction of an operated target through using a computer input device according to claim 8, wherein the firmware further determines the corresponding motion to be performed according to a depicted curve of the finger touch motion.

14. The method for controlling a direction of an operated target through using a computer input device according to claim 13, wherein relations between the curve and the corresponding motion are listed as follows:

when the curve is a clockwise 90-degree curve, the motion is to rotate rightward by 90 degrees;

when the curve is an anticlockwise 90-degree curve, the motion is to rotate leftward by 90 degrees;
