Validation of Ergonomics Evaluation Method Based on Eye Tracking Technology in Unmanned Aerial System

Abstract

Ergonomics evaluation of aircraft cockpit interface is the way to apply human-centered design philosophy. This study aims to explore Ergonomics evaluation method based on eye tracking technology which could be used in UVA control station. Methods A total of 31 operation tasks were developed and each one aimed at one function unit of the UVA system. Ergonomics evaluation by eye tracking technology and expert subjective analysis were both done to diagnose the design problems. A total of 12 male UVA pilots participated in the experiment. Results A total of 13 units were diagnosed as low level by eye tracking method, while 14 units were evaluated as low level by subjective evaluation. McNemar test results show that the difference between two methods was not significant (P > 0.05). One-way ANOVA test shows pupil diameter of low-level Ergonomics tasks was significantly longer than that of the high-level task (P < 0.05). Conclusion Combination of two methods was the practical Ergonomics evaluation method in UAV control station interface.
