104. Receiving a target process confirmation instruction, and determining a target process and a target audio according to the target process confirmation instruction and the monitoring mapping table;
when a user needs to screen a certain process, the user can input information for screen projection of the certain process into the system by using the input equipment, wherein the information comprises a target process confirming instruction; at this time, the system receives a confirmation target process instruction, for example: when the user needs to screen process 1, the system receives an instruction for confirming that process 1 is the target process.
After receiving the command of the target process, the system determines the target process according to the command of the target process and the monitoring mapping table established in step 103, and further determines the audio corresponding to the target process, i.e. the target audio, according to the target process.
105. And visually projecting the target process and the target audio by using a callback function of the monitor.
