Problems solved by technology
Since there are many factors affecting the ergonomics effect, and they are related to each person’s psychological factors, the mainstream evaluation mainly adopts the method of scoring or fuzzy evaluation based on expert experience, which tends to be subjective and qualitative, such as the expert system evaluation method, and there is no perfect comprehensive method. Index system and evaluation criteria lack sufficient theoretical support and detailed quantitative description

The invention provides a man-machine ergonomics quantitative assessment method for a man-machine interface design of a cockpit display. The method comprises the steps of performing fitting according to tracking processing time of an eye tracker to obtain brain identification time t1 consumed by icons with different spatial frequencies; when a to-be-observed icon deviates from the center of a current visual field range of human eyes, calculating time t2 required for rotating the human eyes at a line-of-sight angle; after the to-be-observed icon is beyond a rotational visual field range of the human eyes in a current position, calculating time t3 required for deviating the center of the visual field to the position of the to-be-observed icon by rotating the head of personnel; then obtaining time cost delta Tij=t1+t2+t3 of each single frame of a captured image; and finally calculating total time Tcost consumed for information capture in a process of executing the whole task by a to-be-assessed man-machine design interface based on task execution process information frequency n and information skip sequence viewing statistics in the task execution process. According to the method, the efficiency of a cockpit display interface can be objectively reflected and human eye visual characteristic-based man-machine ergonomics quantitative assessment of the interface is carried out.
Description
technical field [0001] The invention relates to a man-machine interface work efficiency evaluation method of a curved surface display system, which is applied to an avionics system. Background technique [0002] The aircraft cockpit display interface is an important part of the cockpit man-machine system, and is the main man-machine interface for pilots to obtain the required information. With the complexity and diversification of the airborne system, the lack of effective and reasonable man-machine design has resulted in excessive and confusing display information, and the problem of the pilot's information capture load has become increasingly prominent, prolonging the time for cognition and judgment. Therefore, the design of the display interface should conform to the visual characteristics of the human eye. [0003] With the maturity of new display technologies such as curved surface display technology, three-dimensional three-dimensional display technology, and virtual ...
