When the key is continuously pressed and the mouse cursor is moved, it is equivalent to the finger moving on the screen. When the key is pressed, it is equivalent to the finger no longer pressing the screen.

Please refer to Fig. 6 again, which is to illustrate the multi-finger touch function. After executing the touch mode, when multiple buttons on the mouse M are pressed continuously at the same time, the computer operating system can perform the multi-finger touch function. Such as: two-pointing right, two-pointing left, two-pointing up, two-pointing down and other touch gestures, that is, when the touch signal conversion unit 20 simultaneously converts multiple mouse buttons (such as the left mouse button M1 and the right mouse button M2) signal, it means that the user operates the mouse M to press down on the screen simultaneously. Furthermore, the touch signal conversion unit 20 simultaneously converts the signals of multiple buttons into touch points and simulates the execution of the multi-finger touch function; for example , when the user presses the left mouse button M1 and the right mouse button M2 at the same time in the touch mode, and then moves the mouse to the right, the touch signal converting unit 20 converts the signal of the left mouse button M1 into a first touch The signals of point P1 and right button M2 are converted into a second touch point P2, and then the first touch point P1 and the second touch point P2 move to the right at the same time; that is, after the touch mode is executed, then press Press and hold down the other buttons, which means that another finger touches the screen, and then move the mouse cursor, which is equivalent to moving all fingers on the screen.

Please refer to FIG. 7, which is the action when the present invention wants to perform the function of zooming in and out or rotating the screen. After the touch mode is executed, when the fixed-point button M4 of the mouse M is pressed, the fixed-point button M4 is activated. The position of the mouse cursor when pressed is converted by the touch signal conversion unit 20 into a fixed first position point P1, the first position point P1 will not move with the mouse cursor, and then move the mouse to select a point on the screen to continue Press and slide to make the touch signal conversion unit 20 convert the selected point into a position point and define it as a movable second position point P2, so that the computer operating system can be centered on the first position point P1 According to the distance between the two touch points P1 and P2, when the second point P2 is close to the first point of P1, the effect of zooming in on the screen will be generated, or when the second point P2 moves away from P1, the effect of zooming in on the screen will be generated Effect;
