title: From SAW to Comspec.
abstract: This paper details the development of two systems Switch Access to Windows (SAW) and Communicator Specification (Comspec). Descriptions are given of the two systems and their development methodologies. Convergence of approach both in the designer and user interfaces as well as the development methodologies arose naturally in the course of development despite starting with what seemed to be very different aims. SAW addresses a particular form of communication, that between a switch user and computer applications. Comspec will, as a comprehensive and expandable communication system, subsume SAW in the long run.
