Gaze-Targeted Video Quality Processing for Motion Sickness

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wide-field videos viewed on large screens at wide angles can cause video motion sickness due to sensitivity in operations like viewpoint switching or zooming, and existing solutions either degrade image quality or fail to prevent regions causing motion sickness from being displayed, leading to frustration and discomfort.

Innovation Solution

An information processing device with a quality analyzer, gaze target region information generation unit, and quality improvement processing unit that generates video viewing quality information and improves the viewing quality of specific regions to prevent motion sickness, ensuring comfortable high-quality viewing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If video is displayed at wide viewing angle on large screen, then viewer immersion is improved, but video motion sickness occurs

Engineering Contradiction:

Improveviewing angleVSAvoidvideo motion sickness

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the screen into multiple regions and applies different image quality settings to each region. The center region maintains high image quality while peripheral regions use lower quality, reducing overall motion sickness triggers while preserving immersion in the central viewing area.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements differential image quality processing where the center region of the screen receives full-quality video processing while peripheral regions receive reduced-quality processing. This local quality adjustment reduces motion sickness in peripheral areas without compromising the immersive experience in the central region.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If image quality is lowered to reduce motion sickness, then video motion sickness is reduced, but visibility and viewer frustration increase

Engineering Contradiction:

Improvevideo motion sicknessVSAvoidimage quality

Core Design Contradiction:

Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent applies different quality levels to different screen regions, maintaining high image quality in the center region where viewers focus attention, while reducing quality in peripheral regions. This resolves the contradiction by preserving visibility and viewer satisfaction in critical areas while reducing motion sickness triggers in less critical peripheral areas.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If viewpoint switching or zooming is implemented, then interactive viewing is improved, but sensitivity to operation changes causes motion sickness

Engineering Contradiction:

Improveinteractive operationVSAvoidvideo motion sickness

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent segments the video processing into center and peripheral regions, applying different motion handling strategies. The center region maintains interactive operations like viewpoint switching and zooming with high quality, while peripheral regions use suppressed motion and lower quality to reduce motion sickness during interactive operations.

Inventive Principle:

Principle #1Segmentation
