Abstract
For seamless control of advanced hand prostheses and augmented reality, accurate and immediate hand gesture recognition is essential. Surface electromyography (sEMG) signals obtained from the forearm are commonly employed for this purpose. In this paper, we present a novel approach for sEMG representation that utilizes graph networks which contain information about muscle activation patterns in the forearm. Based on these graph networks, we have developed a machine learning algorithm capable of real-time hand gesture recognition using a graph neural network. The algorithm's performance was evaluated using sEMG signals acquired from myoband, which has 8 electrodes placed around the forearm, involving 8 healthy subjects. The proposed method demonstrated an average classification accuracy of 99%, surpassing the performance of state-of-the-art techniques. The average time for both graph construction and prediction stood at 48ms utilizing a M1 Pro CPU, rendering the approach well-suited for real-time applications.
Blogger's Review: This paper showcases the potential of graph neural networks in processing sEMG signals, particularly in the realm of real-time gesture recognition. With an impressive accuracy of 99% and rapid response time, it opens new avenues for prosthetic control and augmented reality interaction. The findings suggest that combining biological signals with graph neural networks can significantly enhance the precision and efficiency of human-computer interaction.
