Abstract

A cursor control device is disclosed to include a fingering with a color mark for fastening to the user'"'"'s one finger, a digital camera for scanning the color mark and to give an image signal to the computer indicative of direction and movement of the fingering, a wireless operating button device for fastening to the user'"'"'s another finger and operable to transmit a control signal to the computer wirelessly, an image processing program installed in the computer for processing the image signal produced by the digital camera for moving the cursor on the display screen, and a button signal processing program installed in the computer for processing the control signal produced by the wireless operating button device and executing the respective command.

Claims

1. A cursor control device installed in a computer for controlling movement of a cursor on a display screen of said computer, the cursor control device comprising:

a fingering for fastening to the user'"'"'s one finger, said fingering carrying a color mark;

a digital camera adapted to scan said color mark and to give an image signal to said computer indicative of direction and movement of said fingering;

a wireless operating button device for fastening to the user'"'"'s another finger and operable to transmit a control signal to said computer wirelessly;

an image processing program installed in said computer and adapted to process the image signal produced by said digital camera and to further drive said computer to move the cursor on the display screen subject to the direction and amount of the movement of said fingering; and

a button signal processing program installed in said computer and adapted to process the control signal produced by said wireless operating button device and to execute the respective command.

2. The cursor control device as claimed in claim 1, wherein said digital camera is programmable to automatically control the scanning direction of said digital camera and to automatically set the color mark of said fingering in the focus of said digital camera.

3. The cursor control device as claimed in claim 1, wherein said color mark of said fingering is detachable.

4. The cursor control device as claimed in claim 1, wherein said image processing program processes the image signal received from said digital camera through one of a low pass filtering process and a delay processing process to prevent executing of a false signal caused by accidental vibration of the finger carrying said fingering.

5. The cursor control device as claimed in claim 1, wherein image processing program controls the cursor on the display screen of said computer subject to the location of said color mark or the amount of movement of said color mark.
