On the other hand, if the user moves the mouse down so that the absolute coordinates of the cursor of the mouse fall within the preset coordinate range, the processor 20 generates a control signal to the switch 40 to be switched by the switch. The cursor is switched to the third computer device at the first computer device such that the cursor is displayed on the third screen SC3.

For another example, assume that the cursor of the mouse originally appears on the fourth screen SC4. At this time, if the user moves the mouse to the left so that the absolute coordinates of the cursor of the mouse fall within the preset coordinate range, the processor 20 A control signal is generated to the switch 40 to switch the cursor to the fourth computer device by the switch to the third computer device such that the cursor is displayed on the third screen SC3. On the other hand, if the user moves the mouse up so that the absolute coordinates of the cursor of the mouse fall within the preset coordinate range, the processor 20 generates a control signal to the switch 40 to switch the cursor by the switch. The fourth computer device is switched to the second computer device such that the cursor is displayed on the second screen SC2.

That is to say, in this embodiment, when the absolute coordinates of the cursor of the mouse fall within a part of the preset coordinate range covering the preset coordinate of the horizontal axis (x _pre , y), the processor 20 generates a control signal to the switch. 40. The switch 40 switches the cursor between the first computer device and the second computer device or between the third computer device and the fourth computer device. On the other hand, when the absolute coordinates of the cursor of the mouse fall within a portion of the preset coordinates covering the preset coordinates (x, y _pre ) of the longitudinal axis, the processor 30 generates a control signal to the switch 40 to be used by the switch 40. The cursor is switched between the first computer device and the third computer device or between the second computer device and the fourth computer device.

As mentioned above, the multi-computer switching system provided by the present invention can have a plurality of shortcut functions.
