Pilot Mental Workload Prediction Model Based on Information Display Interface

Abstract

To predict the changes of mental workload for the pilot, a mental workload prediction model based on the information display interface, which comprehensively considering the influences of time pressure, information intensity and multidimensional information coding on mental workload, was proposed. In order to verify the validity of the model, 20 subjects performed an indicators monitoring task under different task conditions. Performance measure, subjective measure and physiological measure were adopted for evaluation the mental workload. The integrated experimental results reveal that the changing trend of mental workload calculated by the theoretical model is relatively highly correlated with the practical experimental results. This mental workload prediction model will provide a reference for the ergonomics evaluation and optimization design of cockpit display interface.
