Abstract

The wireless human input device comprises at least one wireless human transmitting unit and a wireless human receiving unit. The wireless human transmitting unit generates leading signals and data signals and transmits the signals to the wireless human receiving unit. The wireless human receiving unit receives all the leading signals and identifies the data signals based on the leading signals so as to distinguish the data signals being transmitted by which wireless human transmitting unit transmitted.

Claims

1. A wireless human input device comprising:

at least one wireless human transmitting unit, generating different leading signals and data signals, and transmitting said signals; and

a wireless human receiving unit, receiving all the leading signals for identifying said wireless human transmitting unit and receiving the data signal corresponding to the leading signals.

2. The wireless human input device as claimed in claim 1, wherein said at least include a waveform signal for setting a waveform length.

3. The wireless human input device as claimed in claim 1, wherein said wireless human transmitting unit is a wireless mouse transmitting unit, a wireless keyboard transmitting unit or a wireless touch pad transmitting unit.

4. The wireless human input device as claimed in claim 1, wherein said wireless human receiving unit is commonly used for said at least wireless human transmitting unit.

5. The wireless human input device as claimed in claim 1, wherein said wireless human transmitting unit at least includes a first electronic circuit device for generating said leading signals.

6. The wireless human input device as claimed in claim 1, wherein said wireless human receiving unit at least includes a second electronic circuit device for identifying said leading signals.
