Abstract

A mouse having a scrolling function includes a mouse body, an optical finger navigation module and a control unit. The optical finger navigation module is used for sensing a motion of a user'"'"'s finger. The control unit controls a frame of a computer to be scrolled at an adjustable scrolling speed according to a moving speed of the user'"'"'s finger.

Claims

1. A mouse having a scrolling function, said mouse being connected to a computer and comprising:

a mouse body;

an optical finger navigation module disposed on said mouse body for sensing a motion of a user'"'"'s finger; and

a control unit connected to said optical finger navigation module for scrolling a frame of said computer, wherein said control unit controls said frame to be scrolled at an adjustable scrolling speed according to a moving speed of said user'"'"'s finger.

2. The mouse having a scrolling function according to claim 1 wherein said optical finger navigation module comprises:

a light source for emitting a light beam;

a reflective mirror for reflecting said light beam onto said user'"'"'s finger;

a focusing lens for focusing said light beam that is reflected by said user'"'"'s finger;

a sensor for generating a sensing signal according to said focused light beam; and

an upper cover for sheltering said optical element and penetrable by said light beam, wherein said upper cover is exposed to a surface of said main body for allowing said user'"'"'s finger to be placed thereon.

3. The mouse having a scrolling function according to claim 2 wherein a data amount of said sensing signal outputted from said sensor to said control unit is determined according to a moving speed of said user'"'"'s finger on said optical finger navigation module.

4. The mouse having a scrolling function according to claim 3 wherein said control unit executes a first scrolling function if said data amount of said sensing signal outputted from said sensor to said control unit is greater than or equal to a threshold value, and said control unit executes a second scrolling function if said data amount of said sensing signal outputted from said sensor to said control unit is smaller than said threshold value.

5. The mouse having a scrolling function according to claim 4 wherein said frame is scrolled in a vertical direction at a first scrolling speed when said control unit executes said first scrolling function, and said frame is scrolled in said vertical direction at a second scrolling speed when said control unit executes said second scrolling function.

6. The mouse having a scrolling function according to claim 5 wherein said first scrolling speed and said second scrolling speed are greater than a preset vertical scrolling speed.

7. The mouse having a scrolling function according to claim 4 wherein said frame is scrolled in a horizontal direction at a first scrolling speed when said control unit executes said first scrolling function, and said frame is scrolled in said horizontal direction at a second scrolling speed when said control unit executes said second scrolling function.

8. The mouse having a scrolling function according to claim 7 wherein said first scrolling speed and said second scrolling speed are greater than a preset horizontal scrolling speed.

9. The mouse having a scrolling function according to claim 2 wherein said upper cover of said optical finger navigation module is made of transparent material.

10. The mouse having a scrolling function according to claim 2 wherein said control unit is a micro-controller.

11. The mouse having a scrolling function according to claim 1 wherein when said user'"'"'s finger is moved on said optical finger navigation module a tilting direction, said control unit analyzes and obtains a vertical component and a horizontal component of a moving vector of said user'"'"'s finger, wherein if said vertical component is greater than said horizontal component, said control unit controls said frame of said computer to be scrolled a vertical direction, and if said vertical component is smaller than said horizontal component, said control unit controls said frame of said computer to be scrolled a horizontal direction.

12. The mouse having a scrolling function according to claim 1 further comprising a mode-changing button, wherein a two-dimensional scrolling function is enabled when said mode-changing button is activated.

13. The mouse having a scrolling function according to claim 12 wherein when said two-dimensional scrolling function is enabled, said control unit controls said frame to be scrolled in a tilting direction according to a tilting motion of said user'"'"'s finger.

14. The mouse having a scrolling function according to claim 1 wherein said computer further comprises a scrolling function driver program executed to enable or disable a two-dimensional scrolling function.

15. The mouse having a scrolling function according to claim 14 wherein when said two-dimensional scrolling function is enabled, said control unit controls said frame to be scrolled in a tilting direction according to a tilting motion of said user'"'"'s finger.
