Abstract:Display interface ergonomics studies usually use time and correct rate as the index to record and analyze the operating process .Display interface needs to be flexible. However, the existing flight simulator cannot meet the demand that mentioned above. In order to study further, the operating process for a pilot is divided into information input, information processing, information output and the time or event records when information input or output changes. To achieve the above requirements, the functional requirements of simulation system and function module should be clear to obtain system overall frame. System simulation module, virtual instrument module, visual module, communication module, data management module of the design process should be described in detail in this paper. After implementing and testing the simulation system, the results show that the simulation system can record the time and state when information input or output changes, that meets the needs of the ergonomics research on display interface and provides a new method in studying display interface ergonomics.
