- Abstract:
-
In order to improve the recognition effects of the "agreement" and "disagreement" attitudes expressed by the body language of the head movements, a surface electromyography (sEMG) approach in combination with the greedy genetic algorithm (GGA) and the Elman neural network is proposed. The sEMG signals of the neck muscles were detected while eight participants were nodding and shaking their heads respectively during a pilot experiment. By means of the Wilcoxon’s signed-rank test, ten features of the sEMG time domain indices were extracted with significant differences. Furthermore, the body language recognition model was constructed based on the Elman network optimized by GGA. Experimental results show that the model can successfully recognize the "agreement and disagreement" attitudes spontaneously expressed by the different body languages of the head. Compared with the recognition models using the standard Elman and BP network, the correlation coefficient of this present model is higher, the mean squared error is less, and the correct recognition rate of the test set is increases by over 3.2%, which demonstrate the reliability of this approach.
