Remote education data interaction system and method based on AR holographic glasses

Abstract

The invention relates to a remote education data interaction system and method based on AR holographic glasses. An audio and video transmission channel is established between AR holographic glasses ofon-site students and a PC or a tablet computer of a remote teacher by means of a webpage real-time communication technology, so that the remote teacher can see a first visual angle picture of the on-site students in real time and perform audio and video communication with the on-site students and other remote teachers. Meanwhile, a synchronous virtual cooperation drawing board is established between students and teachers by utilizing a Canvas technology, and a remote teacher can freely add virtual assistance information such as drawings and characters on an on-site video picture. Then, the virtual cooperation information is synchronously pushed to the student AR holographic glasses end and other remote teacher ends by means of the established channel, and the student AR holographic glasses end realizes "enhancement" on the scene where the on-site student is located through superposition display of the virtual assistance information on the virtual screen. Compared with the prior art, the system has the advantages of liberating two hands of a student, realizing multi-person real-time communication and the like.

Description

technical field [0001] The present invention relates to the technical field of network education, in particular to a remote education data interaction system and method based on AR holographic glasses. Background technique [0002] Distance education is a new type of education. The biggest feature of this kind of education is that there are not many opportunities for teachers and students to meet each other throughout the teaching activities, that is, "teachers and students are relatively separated in the whole process of teaching and learning. state". At present, the mainstream distance education collaboration methods rely on traditional media such as video, voice, and text, such as remote video conferencing, remote telephone communication, and so on. In the most popular remote video conferencing, traditional video conferencing technologies include MCU, H.323, frame relay, etc. With the continuous advancement of technology, some new technologies have emerged, including the...

AI Technical Summary

Problems solved by technology

With the development of augmented reality technology, some new distance education methods based on augmented reality technology have been proposed one after another, such as the virtual interaction method in which remote experts can guide local doctors to perform surgical operations. However, this method has the disadvantages of too complicated equipment and poor system versatility. Problem; the existing technology also includes a method for students and teachers to save and share the stylus with the help of the optical see-through head display device, but this method has the disadvantage of not being able to communicate with multiple people in real time
