Effects of proprioception and visual focus of attention on surface electromyography proportional control

Abstract

This paper aimed to study the influence of proprioception and visual focus of attention on predicting elbow angles. The experiments were conducted in two directions with three psychological factors in each direction. Then, the method of pattern recognition was used to predict the elbow angles. Finally, the accuracy of the predicted error was verified by using the root mean square error, and the coherence coefficient of the myocardium was used to analyze the effect of various factors on the recognition accuracy. The results showed that a change in the subject's external focus of attention and proprioception improved the recognition accuracy of the elbow. The methods and results of the paper can be the basis to optimize surface electromyography (sEMG) control. Finding the relationship between psychological factors and control could enable improvements in the performance of human-computer interactions.
