Mixed Reality Display Synchronizing Shutter Glasses for Luminance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mixed reality display systems fail to allow users on both sides of a transparent display to see each other and virtual objects simultaneously, lacking the ability to compensate for distinct luminances on different sides.
Innovation Solution
A mixed reality display system comprising a transparent display and synchronized shutter glasses, where users wear controllable shutter glasses to enable viewing of each other and virtual objects, with a controller coordinating the display and glasses to manage luminance differences through pulse-width modulation signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a transparent display is used to allow users to see through it, then users can see each other on both sides, but the luminance on different sides becomes distinct and difficult to compensate
Solution Approach 1:
The patent applies local quality by adjusting the transparency or opacity of different regions of the transparent display independently. Each region can be optimized to compensate for its specific luminance characteristics, allowing users on both sides to see each other clearly while maintaining overall luminance balance.
Solution Approach 2:
The patent changes the optical parameters of the transparent display dynamically. By adjusting parameters such as transparency, opacity, or light transmission properties in response to detected luminance differences, the system compensates for distinct luminances on different sides while preserving the see-through capability.
2Adaptability or versatility
If virtual objects are displayed on the transparent display, then immersive mixed reality experience is provided, but users cannot see real people and virtual objects simultaneously on both sides
Solution Approach 1:
The patent uses periodic action through alternating display modes. The transparent display switches between showing virtual objects and showing real-world content in periodic cycles, allowing users to access both virtual and real information sequentially. This resolves the contradiction by providing both types of content while managing visibility through time-based separation.
Solution Approach 2:
The patent applies dynamics by making the display characteristics adjustable and changeable. The system can dynamically switch between different transparency levels, display modes, and content priorities based on user needs and environmental conditions, enabling both immersive virtual experiences and clear visibility of real people.
3Illumination intensity
If shutter glasses are used to manage luminance differences, then users can see both real and virtual content, but the system complexity increases with synchronization requirements
Solution Approach 1:
The patent introduces an intermediary controller that manages the synchronization between the transparent display and shutter glasses. This intermediary device coordinates the operation of both components, handling the complexity of timing and synchronization while presenting a simplified interface to users and reducing the burden on the main system architecture.
