Abstract

Purpose: To improve the operating speed of the traditional row-column scanning computer keyboard-mouse composite panel controlled using a single key. Method: Using a single mouse input control window can avoid scanning unnecessary keyboard characters, thereby increasing the speed in performing mouse commands. In addition, the surface

electromyographic ( SEMG) sensing input can also be used to provide an input option for the disabled. Results: Eleven volunteers operated the single mouse input control window using the SEMG input and the traditional computer keyboard- mouse composite panel controlled using a single key. The average operating times were 121.3 +/- 8.9 sec and 208.6 +/- 10.7 sec, respectively. The difference was statistically significant (p < 0.05). Conclusions: The row-column scanning method with the single mouse control window using SEMG input can effectively decrease the operating time. Through this system, the disabled can operate a computer and lead an independent life
