Abstract

A computer input device includes a control unit, a coordinate detecting module for detecting movement of the input device on a working surface, a roller on the body of the input device for generating a first scrolling signal, and a function key. When a user activates the function key and moves the input device, then the control unit will generate a second scrolling signal to cause both horizontal and vertical scrolling in response to detection of movement by the coordinate detecting device.

Claims

1. An input device arranged to communicate with a computer for scrolling a displayed application, the input device comprising:

a control unit coupled to a coordinate detecting module, a roller and a function key;

wherein the coordinate detecting module detects a movement such that the control unit moves a cursor on a display of the computer in response to the detection of movement;

wherein an operation of the roller make the control unit send a first signal to the computer to cause scrolling of the displayed application in a single direction;

wherein when both the function key is activated and the coordinate detecting device detects the movement, the control unit sends a second signal to the computer; and

wherein the second signal selectively causes vertical scrolling, horizontal scrolling, or vertical and horizontal scrolling of the displayed application in response to detection of movement by the coordinate detecting device.

2. The input device as claimed in claim 1, wherein the computer has a program for receiving the first signal and the second signal to control scrolling of the display by displacing a vertical scrolling bar and a horizontal scrolling bar.

3. The input device as claimed in claim 1, wherein the control unit generates the second signal to control the scrolling of the display by displacing a vertical scrolling bar and a horizontal scrolling bar.

4. The input device as claimed in claim 1, wherein when the function key is activated, the control unit sends a third signal to execute a predetermined function or command.

5. The input device as claimed in claim 4, wherein the predetermined function or command is a multimedia device controlling function.

6. The input device as claimed in claim 1, wherein the function key is located on a surface of the input device.

7. The input device as claimed in claim 6, wherein the function key is located around the roller.

8. The input device as claimed in claim 1, wherein the input device is selected from the group consisting of a computer mouse, a trackball, a keyboard, and a touch pad.

9. The input device as claimed in claim 1, wherein the input device is a wireless input device.

10. The input device as claimed in claim 1, wherein the second signal controls a speed of the scrolling based on the amount of the movement.

11. The input device as claimed in claim 1, wherein when the movement is horizontal, the second signal controls the scrolling of the horizontal scrolling bar.

12. The input device as claimed in claim 1, wherein the display application is a Windows™

application.

13. The input device as claimed in claim 1, wherein when the movement is vertical, the second signal controls the scrolling of the vertical scrolling bar.
