And the matching operation information transfer to display unit is shown；
The pairing behaviour that the display unit that the one-way visible light sending device inputs according to the input block is shown
Make the pairing of information realization and the visible optical pickup apparatus.
9. according to the method for claim 8, it is characterised in that the one-way visible light sending device is single according to the input
The pairing of the matching operation information realization and the visible optical pickup apparatus that the display unit of member input is shown includes：
The input block inputs the matching operation information that the display unit is shown；
After the input that the input block completes the matching operation information, the visible ray transmitting element sends pair verification
Information；
If the visible optical pickup apparatus judges to know that the pair verification information by checking, is sent to the contrast means
Successful matching information；
The contrast means prompt successful matching according to the successful matching information.
10. according to the method for claim 9, it is characterised in that also include：
When the input block inputs the matching operation information that the display unit is shown, the visible ray transmitting element hair
Go out the visible optical information of corresponding matching operation；
The contrast means receive the visible optical information of the matching operation, if judge to know the visible optical information of the matching operation with
The matching operation information is consistent, then prompts the input of the matching operation information correct.
