Evaluation research of joystick in flight deck based on accuracy and muscle fatigue

Abstract

Human factors have been the main reason of flight accidents, in which misoperation of pilots plays an important role. According to Statistics, in the field of accidents caused by human error accounted for about 80%. The layout design of aircraft cockpit and different controller locations result in different situations of muscle fatigue. Since the situation of muscle fatigue has an effect on the response accuracy, the probability of misoperations increases. The situation of muscle fatigue can be reflected by variables of the sEMG signal. This paper aims to verify the relationship between muscle fatigue and response accuracy based on analysis of sEMG signal. In the experiment, we investigated changes of response accuracy using joystick controller to trace the static object and dynamic object, along with the change of the situations of muscle fatigue. The terminal experiment result can provide information and design method of flight deck to make flight deck safer and more comfortable. © 2014 Springer International Publishing.
