The visual characteristics are important factors influencing the cognition and memory of the icon. In order to study the process of memory coding of feature binding in working memory of icon, the experiment requires 20 subjects to remember whether the icon features or feature binding are consistent and response quickly by pressing buttons, and the behaviour data and ERP data of the subjects are recorded. The experiment results show that compared with single feature memory of an icon, the accuracy under the icon-color feature binding memory condition is lower and the reaction time is longer while the P300 brain electric component with larger amplitude can be triggered. Studies have shown that the binding of visual features in icon memory requires additional cognitive resources. Compared with the other three memory conditions, the latency of the P300 under icon semantic-color feature binding is more significant, indicating that the task of semantic coding of icon is more difficult to complete and the cognitive load is greater.

This is a research report on the improvement of the humanized elements of unmanned system control station design. For this purpose, the first step is to set the ergonomics elements in control station design as user requirements, which are divided into three levels: physiological needs, psychological needs, and ergonomic needs. Besides, by further proposing analytical method based on user requirements priorities of AHP, the authors of the present report employ HOQ combining user requirements and their corresponding ergonomic design characteristics to solve relative design problems through TRIZ theory related methods. Finally, the feasibility and effectiveness of the above techniques and methods are verified by use of examples.

In the design of digital interface of eye control system, interactive control is an important element, and it's convenience directly affects the operation efficiency of the system. In order to reduce the cognitive load of users in the process of eye movement interaction and improve the user experience of eye control system. An ergonomic experiment is designed to explore the input characteristics of gaze interactive controls. The main purpose is to determine the position advantages of the interactive controls. By comparing the scanning velocity between interactive controls, the priority order between interactive controls is obtained. It provides a scientific theoretical basis for the arrangement of the position of interactive controls in the eye control system interface design.
