时间压力下驾驶舱界面视觉搜索绩效研究

To investigate the search characteristics of aircraft cockpit interfaces under different time pressures to improve task performance, the visual search trajectories and task performance data of the subjects were obtained by simulating the task search process under aircraft flight conditions, using such methods as eye tracking, performance evaluation and scale measurement, and then the multi-channel data obtained were analyzed. The results showed that there are significant differences in the visual search characteristics of the subjects under different time pressures(none, low, high) and different interface complexity(simple, complex); both high time pressures and complex interface displays placed a high cognitive load on the subjects; and there is aninverted U-shaped relationship between time pressures in the simple interface displays. It provides a scientific basis for the design of complex human-machine interfaces in aircraft cockpits.
