摘要：Computers and computer-based technology have become an integral part of the lives of many individuals with disabilities. One of the most common activities that can be computer assisted is the generation of text. People who cannot accurately control their extremities (due to disabilities such as cerebral palsy and spinal cord injury) use computers as writing tools. People whose physical disability restricts their spoken output may use a computer as a communication prosthesis. In both cases, the generation of text is a necessary activity that can be physically demanding. It should be made as easy for the user as possible. While the standard computer keyboard is an efficient interface for able-bodied people and some disabled people, it may present significant access problems for others. In these cases some alternative interface is necessary.
