step 410: and acquiring the control operation information of the current user.
The control operation information comprises keyboard trigger information and mouse trigger information; the keyboard trigger information is a signal generated by triggering any key on the keyboard, and the mouse trigger information is a signal generated by moving or clicking the mouse.
Step 420: corresponding control operation information is not received within a preset control authority time period; the current user loses the control authority of the host corresponding to the current host identification information and keeps the display picture of the host corresponding to the current host identification information.
The preset control authority time period is preferably 10 minutes, namely, if the control operation information is not received within 10 minutes, the coordinator is forced to exit the control authority for being controlled by other people, but the display picture originally displaying the corresponding host computer is reserved until the coordinator acquires the control authority of other host computers again.
Step 430: if the corresponding coordinator loses the control authority of the host, the host sends prompt information to the other hosts to prompt that the control authority of the host can be acquired.
The prompt message is pop-up window information and/or short message information and/or light indication information and/or sound prompt information. Different reminding modes can be suitable for different application place environments, multiple prompting modes can be used independently or in combination, and it is guaranteed that other operators can obtain the information as far as possible.
In order to avoid the situation that the resource is wasted because the coordinator still does not perform any operation when acquiring the control authority, the coordinator is forced to quit the control authority for the situation; to further ensure the utilization of the material, the control right may be directly assigned according to the previous priority. The main flow is described as follows:
step 510: acquiring a plurality of current trigger information to form priorities according to the trigger sequence and reserving the current trigger information triggered by corresponding different coordinators according to the priorities;
step 520: and if the corresponding coordinator loses the control authority of the host, sequentially acquiring the control authority of the host according to the current trigger information triggered by the corresponding coordinator in the priority sequence and displaying a display picture of the host.
