A dynamic time warping algorithm of gesture recognition was used to improve the performance of dynamic gesture recognition based on accelerometer.The similarity between test template and reference template is calculated by dynamic time warping method(DTW),and the results of recognition are got from these similarities.To confirm our algorithm,a wireless gesture acceleration measurement system is proposed and measurements gesture information on 41 volunteers is collected.The results show that the average gesture rate is above 97%.Compared with the algorithm of hidden Markov model(HMM),the DTW algorithm is more precise in recognition accuracy.
