The present invention relates to a mouse input device and method of a computer system capable of scrolling an internal screen.

In general, modern computer systems are designed to use so-called "Mouse-Icon" user interface graphics. This type of user interface system allows a computer operator to select a program and generate an input command without knowledge or storage of any particular input command or sequence.

The user simply invokes a variety of graphical screen displays that include command information and symbols called "Icons."

By using a two-dimensional motion detector such as the mouse input shown in FIG. 1, the operator places a mouse pointer on the screen at the selected icon symbol and selects one on the mouse input to select a program or generate computer input commands. Operate the above button.

The computer system controls the screen position of the mouse pointer based on the movement command generated by using the mouse input device. The operator moves the mouse input along a flat surface to rotate the trackball (in the case of an optical mouse, an optical sensor) in the mouse input, so that X and Y scan commands are generated and entered into the computer.

The computer system controls the screen position of the mouse pointer based on the generated movement command by using the mouse input device.

Since the operator moves the mouse along a flat surface to rotate the trackball in the mouse case, a scan signal of the X and Y axes is generated from the mouse and input to the computer, and the computer transmits the mouse scan signal to the position of the X and Y axes. Convert to a signal and place the mouse pointer on the screen accordingly.

On the other hand, since documents on a document writer or web browser are not generally displayed on one screen of the computer system among those represented on the screen of the computer system, these documents are located on the left and right sides of the active window or on the upper and lower edges. A mouse pointer is placed on a scroll bar, and a user drags the scroll bar to scroll in a vertical or horizontal direction.

However, in the conventional mouse input device as described above, in order to drag the scroll bar, the mouse pointer must be placed on the scroll bar located at the outline of the active window, and the mouse pointer is moved on the scroll bar while pressing the button of the mouse. Since the operation to scroll the screen is cumbersome and the number of operations is frequent, there was a problem that the wrist of the operator is generated.

Accordingly, an object of the present invention is to provide a mouse input device and method for a computer system that can more easily scroll an internal screen of an active window among screens of a computer system. have.
