Layered 3D Entertainment System Resolving Accommodation-Vergence Conflict
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D entertainment technologies face challenges in providing comfortable viewing experiences due to accommodation-vergence conflicts, particularly with large negative parallaxes that can cause physiological discomfort, limiting the use of deep negative parallax in cinema experiences.
Innovation Solution
The implementation of a layered augmented 3D entertainment system that uses a combination of shared displays and wearable device displays to create a unified 3D image space, where visual objects can appear to float in front of the viewer, allowing positive parallax rendering on both displays to avoid accommodation-vergence conflicts, using tensor maps and layer-separation surfaces to generate and render image layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If large negative parallax is used in 3D rendering, then depth perception is enhanced, but accommodation-vergence conflict causes physiological discomfort
Solution Approach 1:
The patent segments the 3D visual content into multiple layers with different depth characteristics. Foreground objects with large negative parallax are separated from background objects, allowing each layer to be rendered with appropriate parallax values. This segmentation enables deep depth perception for foreground objects while maintaining comfortable viewing for background objects, resolving the accommodation-vergence conflict.
Solution Approach 2:
Different parallax values are applied to different spatial regions and depth layers of the 3D scene. Foreground objects receive large negative parallax for enhanced depth perception, while background objects use smaller parallax values to avoid discomfort. This localized application of quality parameters allows optimal depth perception without inducing physiological discomfort across the entire scene.
2Object-affected harmful factors
If positive parallax is used on both cinema and wearable displays, then accommodation-vergence conflict is avoided, but depth range is limited
Solution Approach 1:
The patent implements a nested display architecture where wearable device displays are positioned within or near the cinema display system. The wearable devices render foreground layers with positive parallax, while the cinema display renders background layers also with positive parallax. This nesting allows both displays to work together with consistent positive parallax, avoiding accommodation-vergence conflict while achieving extended depth range through the combined layers.
Solution Approach 2:
The patent adds the dimension of multiple display layers to the traditional single-display 3D system. By distributing different depth layers across cinema and wearable displays, the system achieves extended depth range without requiring negative parallax on either display. The combined positive parallax layers create a comprehensive depth experience that avoids physiological discomfort.
3Measurement precision
If layered augmented 3D system is implemented, then depth perception and comfort are improved, but device complexity increases
Solution Approach 1:
The patent designs the layered augmented 3D system with universal components that serve multiple functions. The tensor map generation and layer-separation surface algorithms are used across different content types and display configurations. The system can adapt to various wearable device types and cinema display setups, reducing overall complexity through standardized multi-functional components rather than specialized hardware for each function.

AI summary
Spatial information that describes spatial locations of visual objects as in a three-dimensional (3D) image space as represented in one or more multi-view unlayered images is accessed. Based on the spatial information, a cinema image layer and one or more device image layers are generated from the one or more multi-view unlayered images. A multi-layer multi-view video signal comprising the cinema image layer and the device image layers is sent to downstream devices for rendering.
