Description

Blackboard capable of switching teaching modes based on VR classroom

Technical Field

The invention relates to the technical field of teaching, in particular to a teaching mode switchable blackboard based on VR classroom.

Background

Virtual reality, abbreviated as VR technology, also called smart technology or artificial environment, is a three-dimensional virtual world generated by computer simulation, and provides the user with simulation of sense organs such as vision, hearing, touch, etc. so that the user can observe the things in the three-dimensional space in time without limitation as if he had his own environment. When the user moves, the computer can immediately perform complex operation, and return the accurate 3D world image to generate the presence. Virtual reality, the scene and character seen are all false, and the consciousness of people is substituted into a virtual world. In comparison, it is not difficult to generate graphic images using computer models. If there is a sufficiently accurate model and sufficient time, we can generate accurate images of various objects under different lighting conditions, but here the key is real time. For example, in flight simulation systems, refreshing of the image is important, and the requirements on image quality are high, and the problem becomes difficult due to the very complex virtual environment. At present, VR technology is issued at a high speed, VR technology and application are applied to the teaching field, and a new generation of VR classroom is produced at the same time. However, when the existing blackboard special for VR classroom is used for teaching, different teaching modes are often switched, and in the past, a double-sided blackboard is adopted for teaching, so that the switching mode is troublesome, and the problem of inconvenience in teaching use is caused.
