摘要

本系統以加速訓練模斯碼學習者，快速學習摩斯碼，並有效輸入於電腦上，摩斯碼訓練系統是以鍵盤、滑鼠、單一按鍵、微控開關或麥克風作輸入，辨識長短音，組合成一般字元，予以顯示。實驗時，以二十分鐘為記憶時間，再進行輸入測試，透過本系統之練習，使用者可有效縮短記憶摩斯碼所需時間，可使身障者快速學習，減輕學習時的負擔。

並列摘要

he purpose of this study is to accelerate Morse Code learning procedure and to use Morse Code in computer input applications. In the computer, Morse Code training system shows or recognizes a character via two possible mechanisms: (1) a combined operation process of keypad input, mouse click and micro switch; or (2) microphone identification of a serial long and short sounds.
The tested individuals will be assessed on input results after a 20-minutes memorial time. With this planned learning system, users can efficiently and effectively shorten Mores learning period and reduce learning difficulty.
