Problems solved by technology

[0009] 2. Excessive system resource usage

During this operation, the operation will take up more system resources

However, the excessive occupation of system resources will bring many strange problems. Such problems are highly concealed and have no fixed path, so it will be very difficult to deal with.

During the test, many faults occurred in the process of frequent key pressing. If the burden on the system caused by key pressing can be reduced, it can be predicted that such hidden faults will be greatly reduced.

[0010] 3. Slow response

Due to the above-mentioned resource occupation problem, it is necessary to wait when deleting characters, and this waiting time can be perceived by the user, which will cause poor user experience.

[0011] 4. Poor accuracy

Since you need to press the delete button continuously during the deletion process, once the control is not good, it will delete the things that you don’t want to delete, which will also cause poor user experience.
