for Non-Vocal Physically Disabled Users

 ABSTRACT

One of the priorities in biomedical engineering is the design of communication systems for users with disabilities who have 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, such as the Chinese language. The present paper discusses an input design 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 mainstream users.
