Stereoscopic 3D Rendering Depth Adjustment for Eye Strain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In real-time stereoscopic 3-D rendering, such as in video gaming, viewers experience eye strain due to the inability to adjust to rapidly moving or transient objects, as manual compensation is not feasible.
Innovation Solution
A method and system that dynamically modify the perceived depth of objects in a scene by identifying and adjusting the binocular disparity based on the rate of change of objects, bringing them closer to the zero plane when their speed or visibility change exceeds a threshold, reducing overall range of perceived depths to alleviate eye strain.

Engineering Contradiction Analysis
1Manufacturing precision
If stereoscopic 3-D rendering is used to create depth perception, then visual realism is improved, but eye strain occurs when objects move rapidly or appear briefly
Solution Approach 1:
The system dynamically adjusts binocular disparity based on object motion characteristics. When an object moves rapidly or appears briefly, the system reduces its binocular disparity to minimize depth perception demands on the viewer's eyes, thereby preventing eye strain while maintaining realistic depth perception for stationary or slowly moving objects
Solution Approach 2:
The system changes the binocular disparity parameter adaptively based on object velocity and visibility duration. By modifying this key stereoscopic parameter in response to object motion states, the system optimizes the balance between visual realism and viewer comfort
2Object-affected harmful factors
If manual compensation of stereoscopic 3-D effects is applied to moving objects, then eye strain is reduced, but real-time rendering becomes impossible
Solution Approach 1:
The system performs automatic compensation of stereoscopic 3-D effects based on object motion detection and classification. The rendering pipeline independently identifies moving objects, determines their motion characteristics, and adjusts their binocular disparity without requiring manual intervention, enabling real-time rendering while reducing eye strain
Solution Approach 2:
The system implements a feedback mechanism where object motion information is continuously monitored and used to adjust binocular disparity in real-time. This closed-loop approach allows the system to respond dynamically to object motion while maintaining high rendering speeds

AI summary
A method and system for rendering scenes in stereoscopic 3-D comprises identifying, or detecting, that a rate of change, of one or more elements of a scene to be rendered in stereoscopic 3-D, satisfies a criterion. The perceived depth of elements of the scene is then dynamically modified, and the scene is rendered. The method can reduce eye strain of a viewer of the scene, since the perceived difference in depth of objects or elements of the scene is reduced while the object is changing position or visibility dramatically.
