Method for switching the use of a shared set of wireless I/O devices between multiple computers
A method for switching the use of a shared set of wireless I/O devices between multiple computers. The method of one embodiment comprises receiving a wireless request at a first machine to switch control of a device to a second machine. Control of the device is relinquished at said first machine. A token is transferred from the first machine to the second machine. Wireless control of the device is established at the second machine.
1. A method comprising:
a first instance of a software program resident and operating on a first machine executing in coordination with a second instance of the software program resident and operating on a second machine to:
receive a wireless request, at the first machine;
switch control of a device to a second machine;
relinquish control of said device at said first machine;
transfer a token from said first machine to said second machine; and
establish wireless control of said device at said second machine.
2. The method of claim 1 further comprising terminating wireless transmissions of commands and data between said first machine and said device.
3. The method of claim 2 further comprising initiating wireless transmissions of commands and data between said second machine and said device.
4. The method of claim 3 wherein said token represents a control key to indicate control ownership of said device.
5. The method of claim 4 wherein said wireless request is generated upon input of a predetermined key combination.
6. The method of claim 5 wherein said device is an input (I/O) device having capability for wireless communication.
7. The method of claim 6 further comprising wherein communications between said first machine, said second machine, and said devices are wireless and lack the presence of cable connections.
8. The method of claim 6 wherein said wireless transmissions and said wireless communication comply to Bluetooth wireless protocol.
9. The method of claim 8 wherein said first machine is a first computer and said second machine is a second computer.
10. The method of claim 9 wherein said I/O device is a keyboard.
11. The method of claim 9 wherein said I/O device is a mouse.
12. The method of claim 9 wherein said I/O device is a graphical display.
13. A system comprising:
a wireless input/output device, said wireless I/O device to be controlled through wireless signals;
a first computer capable of wireless communication, wherein said first computer includes a first instance of switching software to assume control of said wireless I/O device;
and a second computer capable of wireless communication, wherein said second computer includes a second instance of switching software to acquire control of said wireless I/O device responsive to a request to switch control generated without a physical switching device.
14. The system of claim 13 wherein said first computer tranmits and receives commands and data with said wireless I/O device while said first computer is in control of said wireless I/O device.
15. The system of claim 14 wherein control of said first computer transmits a token to said second computer when said request to switch control is received at said first computer.
16. The system of claim 15 wherein said first computer gives up control of said wireless I/O device when said request to switch control is received at said first computer.
17. The system of claim 16 wherein said second computer takes control of said wireless I/O device when said token is received at said second computer.
