1. Reduce the user's operation steps, just like a scanner, the operation is simple and efficient.

2. The eyes are the main thread, while the ears are the Interrupt System.

For example, after a user sends a print command from a computer to print hundreds of pages of files, the printer starts to work, but during the printing period, the user may be busy reading and writingProgramHuman eyes are really important and busy, and almost everything needs the participation of eyes to proceed smoothly. Therefore, the eye is the main thread and should be used to maximize its efficiency. That is to say, the user will focus his eyes on the most important thing. Obviously, after sending the print command, the print task is automatically handed over to the printer, and the print task drops from the highest priority to the lower priority. Then, how can users monitor the completion status of tasks with lower priority, and display that the task can be implemented through event interruptions. How can I send an interruption notification to the user after the print task is completed? At this time, the user's eyes are busy, obviously like a single task processor, when executing other tasks, there is no time to monitor printed tasks. Then, after excluding the eyes, we should make an idea on other human body sensory organs, such as ears. Ears are really a multi-task processor. while listening to music, you can hear your friends talking to you and hear other abnormal sounds in the surrounding environment, for example, an earthquake warning. On the other hand, people's eyes are too narrow, and both eyes are in front of each other, so the situation next to them and the situation behind them cannot be monitored in real time. What about ears, because the sound transmitted in the media is not oriented, that is to say, the sound emitted by a sound source can be transmitted in all directions, now we can hear other sounds when listening to music. It can be seen that in the design of human-machine engineering, sound is a very suitable interruption signal. After you set your machine to start working, you don't have to monitor it with limited eyes, instead, let the machine make a sound and tell you how the machine works in real time. This will not disturb your other work, but also monitor the working status of the machine in real time.
