Abstract

Morse code is the most basic emergency communication method. It expresses alphabet and numbers by using the combinations of dots and dashes. Because of its simple structure which only contains dots and dashes, Morse code is expressed in a variety of ways. Among the methods of expressing Morse code, methods that use human body movements such as finger gesture, tongue movements and eye blinking have been studied. Our research uses surface electromyography (EMG) signals generated by hand motion. We expressed Morse code according to the duration between folding and stretching the fist. Experimentally, we have shown that the performance is 100% accuracy in recognizing 26 alphabets.
