A Unit Task Simulator for Off-Line Evaluation of Man/Computer Interfaces

A method is shown for simulating individual operator man/computer tasks and collecting performance statistics. This method employs a minicomputer with structured software that receives user-written programs for the specific processes and for display formatting. Users can easily try out and evaluate alternative interface designs, different combinations of task assignments, or various formatting dialogues. Job and task performance characteristics are directly obtained. An illustration is given. These performance characteristics may be used comparatively or as inputs to a total system simulation for the design of large man/machine systems.
