Smart Device 3D Image Capture System Resolving Vergence-Accommodation Conflict
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D image viewing technologies often cause discomfort and fatigue due to misalignment between vergence and accommodation responses, leading to perceptual depth distortions and difficulties in focusing, as they disrupt the natural correlation between these processes.
Innovation Solution
A smart device system with multiple digital image capture devices positioned linearly within an interpupillary distance captures a series of 2D images, aligns them based on a key subject point, and displays a simulated 3D image sequence, adjusting focus to match stereoscopic retinal disparity and align vergence and accommodation cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional 3D image viewing technologies are used, then 3D depth perception is achieved, but viewer comfort deteriorates due to vergence-accommodation conflict
Solution Approach 1:
The patent changes the vergence parameter by displaying multiple images at different horizontal positions corresponding to different viewing distances. This allows the vergence angle to match the accommodative distance for each image, resolving the vergence-accommodation conflict that causes viewer discomfort in traditional 3D displays.
Solution Approach 2:
The patent adds a horizontal dimension to image display by presenting multiple images side-by-side at different horizontal positions. This spatial arrangement encodes depth information through horizontal position while maintaining proper vergence-accommodation coupling, unlike traditional stereoscopic methods that fix accommodation at display distance.
2Reliability
If multiple images are displayed at different horizontal positions, then vergence-accommodation coupling is restored, but display complexity increases
Solution Approach 1:
The patent uses a standard display device to present multiple images simultaneously, leveraging the display's existing capability to show multiple content elements. This approach achieves complex vergence-accommodation coupling without requiring specialized hardware, maintaining universality across different display platforms.
Solution Approach 2:
The patent creates multiple copies of the same visual content and displays them at different horizontal positions. Each copy represents the scene from a different vergence distance, allowing the viewer's eyes to converge at different angles while maintaining proper focus, thus achieving natural viewing without additional optical components.
3Measurement precision
If images are captured at interpupillary distance separation, then binocular disparity is accurately captured, but device size increases
Solution Approach 1:
The patent segments the image capture function into multiple separate capture devices positioned at different horizontal locations corresponding to interpupillary distance. This segmentation allows accurate binocular disparity capture while keeping each individual device compact, avoiding the need for a single large complex system.
Solution Approach 2:
The patent uses computational processing as an intermediary to combine images from multiple capture devices and generate the final multi-distance image sequence. This computational mediation allows accurate disparity capture from spatially separated devices while the final display can be rendered on a standard-sized screen, decoupling capture geometry from display size.
