Abstract

A method for utilizing a three-dimensional (3-D) mouse in a graphic-user-interface based operating system, such as the WINDOWS operating systems from Microsoft Corporation, is provided. This method allows the 3-D mouse to emulate the functions of the IntelliMouse from Microsoft Corporation, including control of the scroll bars of the active window and special functions such as the auto-scrolling operation and the fast-scrolling operation. Provided that the active window is able to read IntelliMouse-compliant windows commands, the 3-D mouse can also be used to carry out the standard IntelliMouse functions, such as scrolling the scroll bars and resizing the active window.

whereas if no, jumping to step (3);

(3) checking whether the third-dimensional signal represents the standard scrolling operation, the auto-scrolling operation, or the fast-scrolling operation;

(3-1) provided that the third-dimensional signal represents the standard scrolling operation mode, performing a standard scrolling operation on the document currently being displayed in the active window;

(3-2) provided that the third-dimensional signal represents the auto-scrolling operation mode, performing an auto-scrolling operation on the document currently being displayed in the active window; and

(3-3) provided that the third-dimensional signal represents the fast-scrolling operation mode, performing a fast-scrolling operation on the document currently being displayed in the active window.

2. The method of claim 1, wherein

the 3-D mouse is of the type using a wheel to generate the third-dimensional signal;

and

in said step (1), the third-dimensional signal representing the standard scrolling operation mode is generated by rolling the wheel on the 3-D mouse.

3. The method of claim 2, wherein in said step (3-1), the standard scrolling operation includes the steps of:

(A1) detecting the current position of the mouse pointer;

(A2) if the mouse pointer is on any one of the scroll bars of the active window, scrolling the scroll bar currently being pointed by the mouse pointer;

(A3) if the mouse pointer is currently not positioned on any one of the scroll bars of the active window, determining which one of the scroll bars is the most likely one that is related to the desired action by the received third-dimensional signal and related handle, direction, and mode of operation accordance with the current setting of Scrolling Direction Control Mode; and

(A4) scrolling the document currently being displayed in the active window by a scrolling amount in proportion to the angular displacement of the wheel on the 3-D mouse.

4. The method of claim 3, wherein the Scrolling Direction Control Mode includes the options of:

an X-axis Mode, which activates the horizontal scroll bar to scroll through the document currently being displayed in the active window horizontally;

an Y-axis Mode, which activates the vertical scroll bar to scroll through the document currently being displayed in the active window vertically; and

a Proximation Mode, which activates the one of the horizontal and vertical scroll bars that is proximate to the mouse pointer.

5. The method of claim 3, further comprising the step of:

switching the currently activated one of the scroll bars to the other in response to the pressing of a keyboard key while rolling the wheel on the 3-D mouse.

6. The method of claim 3, wherein in said step (A4), the scrolling amount is set in such a manner that each unit of the angular displacement of the wheel on the 3-D mouse causes the currently activated one of the scroll bars to scroll three lines of the document currently being displayed in the active window.

7. The method of claim 1, wherein in said step (1), the third-dimensional signal representing the auto-scrolling operation mode is generated by pressing the wheel on the 3-D mouse once.

8. The method of claim 1, wherein in said step (1), the third-dimensional signal representing the fast-scrolling operation mode is generated by continuously pressing the wheel on the 3-D mouse.

9. The method of claim 1, wherein in said step (1), the third-dimensional signal representing the auto-scrolling operation mode is generated by pressing the wheel on the 3-D mouse once;

and the third-dimensional signal representing the fast-scrolling operation mode is generated by continuously pressing the wheel on the 3-D mouse.

10. The method of claim 9, further comprising, in the case of the received third-dimensional signal representing the auto-scrolling operation, the following steps of:

(B1) stopping the transfer of the pointer-control signal from the 3-D mouse to the operating system;

(B2) registering the time at which the wheel on the 3-D mouse was pressed;

(B3) registering the time length during which the wheel has been maintained in pressed state;

(B4) comparing the registered time length with a preset value to see if the registered time length is greater than a preset value;

if no, performing an auto-scrolling operation;

whereas if yes, performing a fast-scrolling operation.

11. The method of claim 10, wherein the pointer-control signal includes information that indicates both the moving direction and the linear displacement of the 3-D mouse.

12. The method of claim 10, wherein the preset value of time length is 0.2 sec.

13. The method of claim 10, wherein the auto-scrolling operation includes the steps of:

(C1) establishing a timer;

(C2) scrolling the currently activated one of the scroll bars of the active window repeatedly at fixed time intervals controlled by the timer;
