Eye Tracking Video Resolution Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional immersive video systems face challenges in efficiently delivering high-quality video content over networks, leading to increased resource consumption and costs, while also limiting the quality of the delivered content.
Innovation Solution
The system employs an eye tracking device to detect the viewer's field of view and adapt the video content resolution accordingly, delivering higher quality content in the viewer's focal area and lower quality content in peripheral areas, thereby optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If immersive video is transferred from a remote source over a network to a display screen, then the video content can be delivered to the consumer, but resource consumption increases and costs increase while limiting the quality of the delivered video content
Solution Approach 1:
The patent applies local quality by delivering video content at different resolutions to different regions of the display based on the viewer's eye position. The central foveal region receives high-resolution content while peripheral regions receive lower-resolution content, optimizing resource usage while maintaining perceived video quality.
2Reliability
If immersive video is transferred from a remote source over a network to a display screen, then the video content can be delivered to the consumer, but resource consumption increases and costs increase
Solution Approach 1:
The system uses eye-tracking data to identify the viewer's foveal region and delivers high-resolution video content only to that specific area, while peripheral regions receive lower-resolution content. This significantly reduces computing resources and network bandwidth requirements while maintaining the viewer's perception of high-quality video.
3Manufacturing precision
If high resolution video content is delivered to the entire video display, then the quality of the delivered video content is high, but resource consumption and costs increase
Solution Approach 1:
The patent implements local quality by adapting video resolution to match the viewer's visual attention. High-resolution content is delivered only to the foveal region where the viewer's eyes are focused, while peripheral regions receive lower-resolution content, thereby maintaining high perceived quality while reducing resource consumption.
Solution Approach 2:
The system dynamically adjusts video resolution based on real-time eye-tracking data. As the viewer's gaze moves across the immersive video content, the high-resolution region is dynamically repositioned to follow the foveal area, ensuring optimal quality where needed while minimizing overall resource usage.

AI summary
A method is provided for displaying an immersive video content according to eye movement of a viewer includes the steps of detecting, using an eye tracking device, a field of view of at least one eye of the viewer, transmitting eye tracking coordinates from the detected field of view to an eye tracking processor, identifying a region on a video display corresponding to the transmitted eye tracking processor, adapting the immersive video content from a video storage device at a first resolution for a first portion of the immersive video content and a second resolution for a second portion of the immersive video content, the first resolution being higher than the second resolution, displaying the first portion of the immersive video content on the video display within a zone, and displaying the second portion of the immersive video content on the video display outside of the zone.
