VR Classroom Content Control for Interactive 3D Teaching Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing educational systems using ICT, such as zSpace and Google Expeditions, struggle to facilitate immersive virtual reality classes and allow students to freely operate three-dimensional teaching materials in a virtual space.
Innovation Solution
A class system that connects a communication class server and viewing terminals, enabling the distribution of panoramic videos from real-space classes, controlling avatar movements, and managing the display and operation of three-dimensional teaching materials based on class progress signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a laptop-type system like zSpace is used, then students can observe objects three-dimensionally and operate displayed models, but it is difficult to use in correspondence education conducted in an immersive virtual reality space
Solution Approach 1:
The patent creates a virtual copy of the physical classroom and teaching materials in an immersive VR space. The three-dimensional teaching material objects are virtual replicas that students can interact with in the virtual environment, allowing correspondence education while maintaining the same operational capabilities as in-person learning.
Solution Approach 2:
The patent transitions from two-dimensional laptop displays to three-dimensional immersive VR environments. Students wear VR headsets to enter a virtual classroom space where teaching materials are displayed as three-dimensional objects, adding the dimension of spatial immersion while preserving interactivity.
2Adaptability or versatility
If a 360-degree panoramic video is used like in Google Expeditions, then students can view immersive content, but a class is not conducted in the virtual space and students cannot freely operate displayed objects
Solution Approach 1:
The patent makes the teaching material objects dynamic by allowing students to freely operate them in the virtual space. Students can select, rotate, zoom, and interact with three-dimensional objects using VR controllers, transforming static panoramic videos into interactive learning experiences where students actively manipulate the teaching materials.
Solution Approach 2:
The system enables students to autonomously operate teaching material objects without teacher intervention. Students can independently select objects, examine them in detail, rotate them, and interact with them according to their own learning needs, making the learning process self-directed while maintaining immersion.
3Reliability
If three-dimensional teaching material objects are displayed in the virtual space, then student understanding is promoted through immersive observation, but the system complexity increases
Solution Approach 1:
The patent segments the complex VR system into distinct functional modules: a classroom imaging system that captures the physical classroom, a transmission system that delivers data to students' devices, and individual student terminals that render the virtual environment. This modular approach manages complexity while maintaining the immersive three-dimensional teaching material display capability.
Data Source
AI summary
A class system for taking a class conducted in an immersive virtual space by connecting a communication class server and a student terminal. The communication class server includes a delivery unit that delivers, to the student terminal, a class content for viewing a class being conducted in the virtual space, and a transmission unit that transmits, to the student terminal, a display signal, a non-display signal, an operation permission signal, and an operation prohibition signal respectively set according to the progress of the class. The student terminal includes a VR function unit that disposes, in the virtual space, an avatar of a student that uses the student terminal and controls the avatar, receives the class content, and displays the class content from the avatar's point of view.
