Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Static media, such as videos, used in online education lack dynamic and personalized content, leading to high bandwidth costs and limited accessibility, especially for mobile users, as they do not provide quantifiable or manipulable data to cater to individual user needs.
Innovation Solution
A virtual and augmented reality instruction system that captures an individual's speech, movement, and handwriting using a board system, tracking system, and sensors, allowing for dynamic content generation and real-time interaction, with features like 3D sensors, augmented reality glasses, and wearable motion controllers to create a virtual learning environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If static media (videos) are used for online education, then educational content can be delivered, but bandwidth costs increase and accessibility is limited
Solution Approach 1:
The patent uses 3D sensors to capture depth information and creates a simplified virtual representation of the physical classroom environment. Instead of streaming high-bandwidth video, the system transmits compact 3D spatial data and renders the environment on user devices, significantly reducing bandwidth requirements while maintaining educational content delivery
Solution Approach 2:
The patent replaces the traditional video streaming mechanism with a virtual environment rendering system. Instead of transmitting pre-recorded video frames, the system captures real-time spatial data using 3D sensors and reconstructs the classroom as a virtual model that can be interacted with, substituting mechanical video playback with computational rendering
2Measurement precision
If video quality is increased, then educational content clarity improves, but bandwidth cost increases
Solution Approach 1:
The system creates a virtual copy of the physical classroom using 3D spatial data rather than high-resolution video. This virtual representation maintains clarity for educational purposes while using minimal data transmission, as it only needs to convey spatial coordinates and object positions rather than full video frames
Solution Approach 2:
The patent changes the fundamental parameters of content delivery from video resolution (width, height, frame rate) to spatial parameters (3D coordinates, depth information). This parameter transformation enables clear educational content delivery at much lower bandwidth costs by rendering graphics mathematically rather than transmitting pixel data
3Adaptability or versatility
If static media is used, then content can be accessed, but dynamic and personalized content cannot be generated
Solution Approach 1:
The system uses tracking systems to continuously monitor student position, orientation, and interaction with virtual objects. This feedback data is used to dynamically adjust the virtual environment and provide personalized learning experiences, allowing the system to adapt content based on individual student needs and behaviors
Solution Approach 2:
The patent transforms the static video environment into a dynamic virtual space where elements can move, interact, and respond to user actions. The virtual classroom allows students to navigate freely, manipulate objects, and receive customized content based on their interactions, creating adaptive learning experiences
4Ease of operation
If virtual reality systems with multiple sensors are used, then interaction and personalization improve, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional integrated system where 3D sensors serve multiple purposes: capturing spatial environment, tracking student position, monitoring gestures, and detecting object interactions. This universal sensor platform provides diverse interaction capabilities without proportionally increasing system complexity, as one sensor array performs multiple measurement functions

AI summary
A virtual and augmented reality instruction system may include a complete format and a portable format. The complete format may include a board system to capture all movement (including writing and erasing) on the board's surface, and a tracking system to capture all physical movements. The portable format may include a touch-enabled device or digital pen and a microphone, and is designed to capture a subset of the data captured by the complete format. In one embodiment of the complete format, the board system and the tracking system can communicate with each other through a network, and control devices (such as a laptop, desktop, mobile phone and tablet) can be used to control the board system and tracking system through the network. In further embodiments of the complete format, augmented reality can be achieved within the tracking system through the combination of 3D sensors and see through augmented reality glasses.
