A new intelligent VR biological learning system based on natural interaction

In middle school biology teaching and learning, there are many biological structures that students need to understand and master. Traditional classrooms mostly use video and PPT to teach, which is not conducive to students' understanding of three-dimensional structure, thus making it difficult to learn biological knowledge. In order to solve the problem of 3D biological structure learning, this paper proposes a natural interaction-based VR biology learning system method, which intelligently perceives the user's interaction intention and interacts with the user through virtual reality technology and multi-modal fusion technology. The innovation of this paper lies in: Firstly, a new VR biological learning system based on natural interaction is proposed. Through the fusion of gestures and speech, the user interacts naturally with the system. This method frees the user's hands from the constraints of the mouse and keyboard and the handle, enhancing the immersion of virtual reality. Secondly, this paper proposes a multi-modal fusion algorithm, which makes full use of the advantages of gestures and speech and compensates for their shortcomings, so as to better perceive the user's operational intention. It makes up for the shortcomings of the virtual learning system's lack of intelligence, so that users get a more convenient and more natural interactive experience. According to the user's experience feedback, the system proposed in this paper can better stimulate students' interest in learning, and can present the abstract three-dimensional knowledge in front of the user more intuitively. It has the good intelligence and the operation experience feeling, can reduce the user's use load effectively, the user operates more conveniently.
