An Input Design for Communication Systems
for Non-Vocal Physically Disabled Users

T.H. Tse 1

[technical report TR-A2-83]


One of the priorities in biomedical engineering is the design of communication systems for users with a disability having both vocal and neuromuscular problems, such as people with cerebral palsy. A major problem is the method of input. It is especially serious if the language used has a large character set, e.g., the Chinese language. This paper discusses an input design that is most suitable for Chinese language communication systems for users with cerebral palsy. It employs a scanning methodology that compares favourably with other encoding methods currently in practice. The design is also useful in Chinese language videotex systems for normal users.
