Design and implementation of the EnableWare specification-a human-machine interface for physically challenging people

EnableWare is a specification and implementation of the human-machine interface (HMI) which enables physically disabled people to access computers. The BTRON HMI specification includes the EnableWare specification in standard. This assures that physically impaired people can use BTRON with no or a little software/hardware modification. The authors first analyze the difficulties of physically impaired people to use computers. Second, they propose EnableWare functions which help motor, visually, and auditory impaired users, and the architecture realizing them. Finally, on the basis of their EnableWare implementation experience on BTRONI, they propose several architectural design guidelines for the HMI system which can be operated by the physically disabled
