Abstract: Implementation of human factors engineering on ship-based situation generation system reflects on the human computer interaction design, including arrangement of staff console, interface display, collaborative interaction, design of hardware structure, and so on. Focusing on cognitional analysis, deduction and decision problems that may be encountered by warfighters in charge of situation generation system, this article applies situational awareness theory to the process of human computer interaction design, especially in the aid decision making display module. An example of a shipboard is given to demonstrate the design idea for situation display and human computer interaction for references finally.
