Development of Interactive Teaching of Physical Dance Based on Dynamic Time Reversion Technique

Abstract

In order to cultivate students' dance expression, in physical dance teaching, emphasis should be placed on cultivating students' interest in physical dance, strengthening the training of movement skills and musical rhythm, training of cultural cultivation, and training of coordination and cooperation between male and female partners. In this paper, we design a dance teaching aid based on DTW (Dynamic Time Warping) movement similarity evaluation algorithm. The evaluation of movement similarity is difficult because each movement is multidimensional, there is a lot of noise when the movement data are collected, and there is high variability in the performance of different individuals, and the real-Time requirement of movement similarity evaluation. In the teaching practice, we should pay attention to the cultivation of students' dance expression, so that students can match the music and make coordinated sports dance movements, realize the integration of music and dance, and improve the professional standard.
