Abstract

A switching device that selectively changes a computer to be operated from multiple computers including a control unit that the control unit detects a cursor position on the computer to be operated based on coordinate data and a computer resolution of the computer to be operated, the coordinate data being generated by performing a same acceleration process as the computer to be operated, on relative coordinate data that has been acquired from a given pointing device, and the control unit selectively changing changes the computer to be operated according to the cursor position. It is thus possible to selectively change the computer to be operated without any dedicated software or requiring a given space for manipulation.

Claims

1. A switching device that selectively changes a computer to be operated from multiple computers comprising a control unit that detects a cursor position on the computer to be operated based on coordinate data and a computer resolution of the computer to be operated, the coordinate data being generated by performing a same acceleration process as the computer to be operated, on relative coordinate data that has been acquired from a given pointing device, the control unit selectively changing the computer to be operated according to the cursor position.

3. The switching device that selectively changes a computer to be operated from multiple computers as claimed in claim 1, wherein the control unit detects a display screen edge.

2. A switching device that selectively changes a computer to be operated from multiple computers comprising a control unit that detects a cursor position on the computer to be operated based on coordinate data and a predicted computer resolution, the coordinate data being generated by performing a same acceleration process as the computer to be operated, on relative coordinate data that has been acquired from a given pointing device, and the predicted computer resolution being greater than a real computer resolution of the computer to be operated, the control unit selectively changing the computer to be operated according to the cursor position.

4. The switching device that selectively changes a computer to be operated from multiple computers as claimed in claim 2, wherein the control unit detects a display screen edge.

5. A switching device that selectively changes a computer to be operated from multiple computers comprising a control unit that detects a display screen edge based on absolute coordinates converted from relative coordinate data that has been acquired from a given pointing device, wherein the control unit selectively changes the computer to be operated if the pointing device exceeds the display screen edge and moves a given amount, based on the absolute coordinates acquired from the pointing device after the display screen edge is detected.

6. The switching device as claimed in claim 5, wherein a cursor is displayed at a position on a screen of the computer to be operated after selectively changing the computer as if the cursor were continuously moving from another computer before selectively changing the computer, based on the absolute coordinates that have been sent to said another computer before selectively changing the computer.

7. A switching device that selectively changes a computer to be operated from multiple computers comprising a control unit that determines whether the computer to be operated is equipped with GUI capabilities, the control unit assigning a switching function of the computer to be operated to a given movement of a pointing device, in a case where the computer to be operated has the GUI capabilities.

8. A switching method of a switching device comprising the steps of:

detecting a cursor position on a computer to be operated based on coordinate data and a computer resolution of the computer to be operated, the coordinate data being generated by performing a same acceleration process as the computer to be operated on relative coordinate data that has been acquired from a given pointing device; and

selectively changing the computer to be operated according to the cursor position.

10. The switching step as claimed in claim 8, wherein the step of detecting detects a display screen edge.

9. A switching method of a switching device comprising the steps of:

detecting a cursor position on a computer to be operated based on coordinate data and a predicted computer resolution, the coordinate data being generated by performing a same acceleration process as the computer to be operated on relative coordinate data that has been acquired from a given pointing device, and the predicted computer resolution being greater than a real computer resolution of the computer to be operated; and

selectively changing the computer to be operated according to the cursor position.

11. The switching step as claimed in claim 9, wherein the step of detecting detects a display screen edge.

12. A switching method of a switching device comprising the steps of:

detecting a display screen edge based on absolute coordinates converted from relative coordinate data that has been acquired from a given pointing device; and

selectively changing a computer to be operated if the pointing device exceeds the display screen edge and moves a given amount, based on the absolute coordinates acquired from the pointing device after the display screen edge is detected.

13. The switching step as claimed in claim 12, wherein a cursor is displayed at a position on a screen of the computer to be operated after selectively changing the computer as if the cursor were continuously moving from another computer before selectively changing the computer, based on the absolute coordinates that have been sent to said another computer before selectively changing the computer.

14. A switching method of a switching device comprising the steps of:

determining whether a computer to be operated is equipped with GUI capabilities; and

assigning a switching function of the computer to be operated to a given movement of a pointing device, in a case where the computer to be operated has the GUI capabilities.
