Research on the Usability Evaluation Model of Human-Computer Interaction for Command and Control System

In view of the present problems encountered in the command and control system, such as lack of scientific and complete indicator system for the human-computer interactive usability, absence of the relevant evaluation model, deficiency of quantitative method of results evaluation, and unavailable comprehensive and quantitative evaluation of the results from tested system, this work analyzed the influence elements of human-computer interaction for command and control system, to build the hierarchical evaluation indices systematically. Ausability evaluation model of human-computer interaction is proposed, which can be used to find the problems of unsafety and inefficiency existing in human-computer interaction of command and control system. Iterative optimization in the procedure of system development is carried out, in order to improve the human-computer interaction of command and control system.
