Application Research and Analysis of College Pole Dance Teaching Based on Virtual Reality Technology

Abstract

With the development of computer virtual reality technology, the application of virtual reality technology in college teaching has been widely applied to simulate various practical scenes. Computer virtual reality technology provides a new teaching method for modern college teaching. For college sports dance teaching, sports dance needs student to imitate the action of teacher in order to achieve the feeling of immersive, so the teacher has a high requirement to the fit degree of student’s dance action and music in the teaching, in order to better use the dance to express feelings in music. Thus it needs synthesis optimization for teaching dance actions and music, to facilitate the teacher’s accurate guidance to the students. However, it is difficult to describe the correspondence between music and dance action by using the current action synthesis optimization method, which leads to the poor synchronization of synthesizing dance action and music changes. To this end, the applied research and analysis of computer virtual reality technology in college sports dance teaching are put forward. The sports dance learning process of this method is completed in the virtual environment. In this paper, the synthesis process of dance action and music is as follows: firstly, combined with the theory of music beat extraction, the synchronized dance action and music data are divided into several smaller fragment combinations of actions - music. The fragments of the music are made mutation point detection, and the predicted position of each obtained beat is aligned, and the correlation coefficient between the dance action and the music segment is calculated, to obtain the objective function of the dance action synthesis optimization. Combined with the ant colony theory, the objective function is optimized and solved. All the music - dance action fragments, according to the pheromone concentration adaptive, are used to adjust the pheromone volatile factor. According to the advantages and disadvantages of the solution of dance action synthesis optimization, the pheromone is dynamically updated, and the dance action synthesis optimization based on virtual reality technology is completed. The experimental results show that the proposed method can fully reflect the synchronization of music and action changes, and the improved method has a higher matching quality of synthesizing music - dance, which effectively improves the quality of sports dance teaching.
