When a system module 10 in a wireless system, such as a desktop integration application and a screen projection integration application, needs to occupy the TouchBar operation, a TouchBar occupation request message is generated, so that the OSD system releases the TouchBar operation.
Step 702: the wireless system notification class message handling module 2012 encapsulates the TouchBar occupancy request message.

After the OSD system releases the occupied TouchBar operation, TouchBar operations acquired by the OSD system are all reported to the wireless system, the used OSD message processing module 201 is a TouchBar message processing module 2014, and the interaction flow is as follows:
step 706: the OSD system sends a TouchBar operation to the UART call module 202.
Step 707: the UART calling module 202 forwards the TouchBar operation to the TouchBar message processing module 2014.
Step 708: the TouchBar message processing module 2014 parses TouchBar operations and translates them into operational events.

Step 709: the TouchBar message processing module 2014 injects operational events into the input subsystem.
Step 710: the input subsystem distributes operational events to the system module 10.
When the system module 10 no longer needs to occupy the TouchBar operation, TouchBar release information for releasing the TouchBar operation is generated and sent to the OSD system, so that the OSD system resumes the occupation of the TouchBar operation, and the used OSD message processing module 201 is the wireless system notification type message processing module 2012.
Step 711: system module 10 sends the TouchBar release information to wireless system notification class message handling module 2012.
Step 712: the wireless system notification class message handling module 2012 encapsulates the TouchBar release information.
The wireless system notification type message processing module 2012 encapsulates the TouchBar release information according to a preset UART format to obtain encapsulated TouchBar release information.
