Virtual learning environment multi-channel fusion display method for field practice teaching

Abstract

The invention belongs to the field of teaching application of a virtual reality technology, and provides a virtual learning environment multi-channel fusion display method for field practice teaching,which comprises three steps of content generation, audio-visual channel fusion and multichannel interaction design. According to the characteristics of teaching contents in a VR learning environment,a set of generation method from data acquisition, knowledge organization and scene switching is established; synchronous updating of audio-visual channels is realized through a space rendering mode;the input and output priorities of each interaction channel are evaluated, and the multi-sensory collaborative interaction of learners in the VR learning environment is completed. Through adding of auditory cues and multi-channel user interaction discrimination modes, the VR learning environment fusion display is realized, the sense of reality of a learning environment can be improved, and the immersion experience of participants is improved.

Description

technical field [0001] The invention belongs to the teaching application field of virtual reality (Virtual Reality, VR) technology, and more specifically relates to a multi-channel fusion display method of a virtual learning environment oriented to field practice teaching. Background technique [0002] Field practice is an important practical link in the training of professionals in geography, geology, biology and other disciplines. It is an important educational activity to train students to integrate theory with practice, master the basic knowledge and basic skills of the discipline, and improve their comprehensive quality and practical innovation ability. However, there are many problems in field practice at present, such as the lack of teachers with solid taxonomic foundation and rich field practice experience; there are many students in practice and the time is short, so it is difficult for teachers to provide "one-to-one" guidance; the practice content and mode are sing...

Problems solved by technology

[0003] Although the current panoramic method can quickly build a realistic field practice VR learning environment, it cannot fully meet the actual needs of field practice teaching

For example, taking the field practice of biology as an example, VR panoramic video can capture images of communication behaviors, social behaviors, and reproductive behaviors between animals, but it is difficult to convey to learners the biological behaviors it metaphors, such as the vocalization mechanism of animals , sound signal characteristics, sound wave reception, processing and recognition are not easy to convey in the picture

Through multi-camera sound synchronization processing, learners can feel the sound differences in all directions, and the sound source changes of panoramic sound simulation can present natural and realistic effects, but this is a situation where the camera positions are relatively fixed, which is difficult to meet the requirements of field practice teaching The demand for all-round presentation of hearing
