Developing interactive systems for the small machine environment

This paper describes the design methods, and tools, for developing interactive systems which will run in the small machine environment. The constraints of this environment are discussed, and it is shown that the requirements of users in this environment are rather stringent, but for systems with a well engineered interface rather than for high performance. The solution adopted is to provide realistic simulation early in the design process, and to provide mechanisms for divorcing the detailed screen layout design from program design.
