Development of Typing Practice System (Fingers) by Identifying a Finger That Presses a Key with a Leap Motion Controller as a Function of Focused Typing Practice with AI

Abstract

While ICT is frequently used in schools, there is still a problem of slow typing by children. Learning by blind touch is the best way to increase typing speed, but many kinds of typing practice software cannot understand whether the key was touched by the correct finger. Thus, we have developed a typing practice system that identifies the fingers touching the keys with a Leap Motion Controller to improve focused typing practice with AI. The evaluation of the program shows that the Leap program occasionally mis-recognizes the fingers, and participants expressed numerous negative opinions about the system's ease of use. However, typing finger mistakes in the test were reduced for all of the participants. The results of the questionnaire indicated that by using this system, participants were able to notice finger mistakes and could make improvements.
