Abstract

A pointing device connected to a computer system is used to control the movement of a cursor in a screen of the computer system. A loop-like touch pad is disposed on the top surface of the pointing device. When a user'"'"'s finger touches and rotates clockwise/counterclockwise on the loop-like touch pad images in the screen can be continuously scrolled downward/upward.

Claims

1. A pointing device connected to a computer system for controlling the movement of a cursor in a screen of the computer system, comprising a loop-like touch pad disposed on the top surface of the pointing device, wherein when the loop-like touch pad receive a clockwise/counterclockwise touch around the center of the loop-like touch pad, images in the screen are continuously scrolled downward/upward.

2. The pointing device of claim 1, wherein the loop like touch pad clockwise/counterclockwise rotated by the clockwise/counterclockwise touch.

3. The pointing device of claim 1, further comprising a circular button disposed at the center of the loop-like touch pad on the top surface of the pointing device.

4. The pointing device of claim 1, further comprising two control buttons respectively disposed at the left and right sides of the loop-like touch pad on the top surface of the pointing device.

5. The pointing device of claim 1, further comprising a trackball assembled at the bottom surface of the pointing device, wherein the trackball roll of the pointing device grasped by a user moves on a contact surface, the cursor moves in the screen by the rolling of the trackball.

6. The pointing device of claim 1, further comprising a cable extending outward from the pointing device to connect with the computer system.

7. A pointing device connected to a computer system for controlling the movement of a cursor in a screen of the computer system, comprising:

a circular button, disposed at the central location near the front side of the top surface of the pointing device;

a loop-like touch pad, disposed around the circular button for controlling the up and down scrolling of images in the screen, wherein when the loop-like touch pad receive a clockwise/counterclockwise touch around the center of the loop-like touch pad, the images in the screen are continuously scrolled downward/upward; and

two control buttons, respectively disposed at the left and right sides of the loop-like touch pad for opening files and executing programs and applications of the computer system.

8. The pointing device of claim 7, further comprising a trackball assembled at the bottom surface of the pointing device, wherein the trackball roll of the pointing device grasped by a user moves on a contact surface, the cursor moves in the screen by the rolling of the trackball.

9. The pointing device of claim 7, further comprising a cable extending outward from the pointing device to connect with the computer system.

10. A pointing device for controlling the movement of a cursor in a screen having images, comprising:

a cursor control element, disposed on the top surface of the pointing device; and

a loop-like touch pad, disposed on the top surface of the pointing device and around the cursor control element to scroll the images in the screen.

11. The pointing device of claim 10, wherein the loop like touch pad clockwise/counterclockwise rotated by the clockwise/counterclockwise touch.

12. The pointing device of claim 10, further comprising two control buttons respectively disposed at the left and right sides of the loop-like touch pad on the top surface of the pointing device.

13. The pointing device of claim 10, further comprising a trackball assembled at the bottom surface of the pointing device, wherein the trackball roll of the pointing device grasped by a user moves on a contact surface, the cursor moves in the screen by the rolling of the trackball.

14. The pointing device of claim 10, further comprising a cable extending outward from the pointing device to connect with the computer system.
