Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 2D display devices limit the ability to provide immersive 3D learning experiences in distance learning settings due to the high cost and proprietary requirements of 3D-enabled display devices, restricting global implementation and effective learning.
Innovation Solution
A 2D/3D conversion interface component that re-formats incoming 3D video streams into a frame sequential format compatible with standard 2D displays, generating a synchronized timing signal for 3D viewing devices, allowing users to experience interactive 3D graphics on conventional 2D displays without the need for expensive 3D display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expensive 3D-enabled display devices are used, then immersive 3D learning experiences are provided, but cost and accessibility are reduced
Solution Approach 1:
A 2D/3D conversion interface component is introduced as an intermediary device between the standard 2D display and the user. This interface component receives 3D video streams, converts them to frame sequential format, and outputs to the 2D display while generating timing signals for 3D viewing devices. This intermediary enables 3D functionality without requiring expensive 3D display hardware, resolving the contradiction between 3D experience quality and cost/accessibility.
Solution Approach 2:
The invention changes the video stream format parameter from side-by-side 3D format to frame sequential format. This parameter transformation allows standard 2D displays to present 3D content when paired with active shutter glasses that synchronize to timing signals. By changing the format parameter rather than the hardware, the system achieves 3D functionality at lower cost.
2Ease of manufacture
If standard 2D display devices are used, then cost and accessibility are improved, but immersive 3D learning experiences are limited
Solution Approach 1:
The conversion interface component enables standard 2D display devices to perform multiple functions - both traditional 2D display and 3D display when paired with active shutter glasses. This multi-functionality allows a single inexpensive device to serve both purposes, improving accessibility while maintaining 3D experience quality through the conversion process.
3Adaptability or versatility
If side-by-side 3D video stream format is used, then 3D content is transmitted, but compatibility with 2D displays is reduced
Solution Approach 1:
The conversion interface acts as a mediator that receives side-by-side 3D video streams and transforms them into frame sequential format. This intermediary conversion process resolves the format incompatibility between side-by-side 3D content and 2D display capabilities, enabling seamless playback without requiring changes to either the content source or the display hardware.
4Manufacturing precision
If 3D viewing devices are synchronized with frame sequential output, then accurate 3D rendering is achieved, but timing signal generation is required
Solution Approach 1:
The conversion interface generates timing signals based on the frame sequential output and transmits them to the 3D viewing devices. This feedback mechanism ensures that the shutter glasses synchronize precisely with the displayed frames, achieving accurate 3D rendering. The timing signal generation adds controlled complexity only where needed to ensure synchronization accuracy.

AI summary
A 2D/3D conversion interface component is configured to override the video processing capabilities associated with a conventional 2D display, re-formatting an incoming 3D video stream into a version compatible with a 2D display while preserving the 3D-type of presentation. An incoming “side-by-side” (SBS) 3D video stream is re-formatted into a “frame sequential” (serialized) format that appears as a conventional video stream input to the 2D display. The interface component also generates as an output a timing signal (synchronized with the converted frames) that is transmitted to a 3D viewing device (e.g., glasses). Therefore, as along as the 3D viewing device remains synchronized with the sequence of frames shown on the 2D display, the user will actually be viewing an interactive 3D video.
