Key belongs to invalid button.
In the angle of incoming frequency, effectively input can be by judging that the speed of the specific button of user is judged.One
As in the case of, speed during one hand typewriting is less than 60 words per minutes, and average individual character key number is 2.98, then one hand can be beaten
The incoming frequency of word sets singlehanded incoming frequency threshold value, the singlehanded incoming frequency threshold value can for 60*2.98/60=2.98/
Second；And speed during both hands typewriting is less than 150 words per minutes, equal individual character key number is 2.98, then what both hands can be typewrited is defeated
Enter the singlehanded incoming frequency threshold value of set of frequency, the both hands incoming frequency threshold value can be 150*2.98/60=7.45/ seconds.And it is double
Hand incoming frequency threshold value is generally larger than singlehanded incoming frequency threshold value, then incoming frequency exceed both hands incoming frequency threshold value then can be with
It is judged as invalid input, incoming frequency then may determine that as effectively input not less than both hands incoming frequency threshold value.
