LEFT/RIGHT HAND OPERATED SENSING INTELLIGENT MOUSE

Abstract

A mouse includes a left button, a right button, a touch sensing unit and a processing unit. The left button and the right button generate click signals in response to click operations. The touch sensing device generates touch positional signals when the left or right button is touched. The processing unit is used to receive the touch positional signals, calculate y-coordinate values of all points in the touched areas; select two significant points respectively from the left touched area and the right touched area; compare the y-coordinate values of the two significant points to generate a comparison result; confirm a current operated mode; if the confirmed operated mode is a left handed operation, send a control signal with a left-button identifier to a computer configured therewith; if the confirmed operated mode is a right handed operation, send a control signal with a right-button identifier to the computer configured therewith.

Claims

1. A left/right hand operated sensing intelligent mouse comprising: a left button and a right button for generating click signals in response to click operations;a touch sensing device for generating touch positional signals when the left or right button is touched; anda processing unit comprising: an identifying module for receiving the touch positional signals generated by the touch sensing unit and determining positions of a left touched area on the left button and a right touched area on the right button;a calculating module for calculating y-coordinate values of all points in the touched areas after receiving click signals generating by the left button and the right button in response to click operations;a selecting module for selecting two significant points respectively from the left touched area and the right touched area, comparing the y-coordinate values of the two significant point, and generating a comparison result, wherein the significant point is a point with a maximal or minimal y-coordinate value of all points in the left touched area or the right touched area;a mode confirming module for determining a current operated mode to be a left handed operated mode or a right handed operated mode according to the comparison result; anda transmission module for generating a control signal according to the current operated mode determined, and sending the control signal to the computer connected therewith.

2. The mouse according to claim 1, wherein if the y-coordinate value of the significant point in the left touched area is smaller than the y-coordinate value of the significant point in the right touched area, the mode confirming module determines a current operated mode is the right handed operated mode.

3. The mouse according to claim 2, wherein in the right handed operated mode, the processing unit sends the control signal with a left-button identifier after receiving the click operation from the left hand, and sends the control signal with a right-button identifier after receiving the click operation from the right hand.

4. The mouse according to claim 1, wherein if the y-coordinate value of the significant point in the left touched area is equal to or greater than the y-coordinate value of the significant point in the right touched area, the mode confirming module determines the current operated mode is the left handed operated mode.

5. The mouse according to claim 4, wherein in the left handed operated mode, the processing unit sends the control signal with a right-button identifier after receiving the click operation from the left hand, and sends the control signal with a left-button identifier after receiving the click operation from the right hand.

6. The mouse according to claim 1, wherein an boundary line between the left button and the right button is set as a y-coordinate axis, a point on the boundary line is set as a center to establish a x-y coordinate system.

7. The mouse according to claim 6, wherein the center of the x-y coordinate system is a start point of the boundary line.

8. The mouse according to claim 6, wherein the center of the x-y coordinate system is an end point of the boundary line.
