Fixed Background Region for 3D Video Motion Sickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video display systems fail to effectively prevent visually induced motion sickness during stereoscopic three-dimensional content viewing, particularly due to factors like afterimages, intense motion, and environmental conditions, beyond just head-mounted display mounting deviations.
Innovation Solution
A video display system that includes a computer displaying three-dimensional video data with a fixed background image region surrounding at least a part of the content video region, adjusting the area ratio and shape of the background to mitigate visually induced motion sickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a three-dimensional video is displayed without a fixed background image region, then the content video region can be maximized, but visually induced motion sickness occurs due to intense motion and lack of visual stability
Solution Approach 1:
The display screen is segmented into two distinct regions: a content video region for displaying the three-dimensional video content and a fixed background image region surrounding the content region. This segmentation allows the content area to be maximized while providing a stable visual reference frame that prevents motion sickness, as the fixed background provides visual stability during head movements.
Solution Approach 2:
The fixed background image region acts as an intermediary element between the moving content video and the viewer's visual system. This intermediary provides a stable reference frame that helps the brain process motion information, reducing the conflict between visual motion perception and vestibular signals that causes motion sickness.
2Stability of the object's composition
If the fixed background image region occupies a large area (20-50% of screen), then visual stability is improved reducing motion sickness, but the available content video display area is reduced
Solution Approach 1:
The fixed background image region is designed to occupy a partial area (20-50% of the screen) rather than the entire display area. This partial action provides sufficient visual stability to prevent motion sickness while minimizing the reduction in content video display area, achieving an optimal balance between visual stability and content visibility.
3Measurement precision
If image processing is applied to rotate or shift the three-dimensional video to correct mounting deviations, then positional accuracy is improved, but the complexity of the display system increases
Solution Approach 1:
Instead of applying complex real-time image processing to rotate or shift the three-dimensional video content, the patent uses a simplified approach by displaying a fixed background image that naturally compensates for mounting deviations. This copying approach creates a stable visual reference that corrects positional inaccuracies without requiring complex processing algorithms.
