Assistive technology (AT) is becoming increasingly important in improving mobility, language and learning capabilities of persons who have disabilities enabling them to function independently and to improve their social opportunities. Morse code has been shown to be a valuable tool in assistive technology, augmentative and alternative communication, rehabilitation, and education, as well as adapted computer access methods via special software programs, hardware devices, and switches. In this study, we designed and implemented an interactive Mandarin phonetic/chanjei Morse code typing emulation system for persons with disabilities, with three adaptive recognition methods.
