Blink-Aware Game Rendering for BVH Resource Reallocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern video gaming systems face challenges in efficiently managing processing resources for rendering display content without impacting perceptual quality, particularly in dynamic environments where re-building bounding volume hierarchies (BVH) is computationally expensive and can lead to choppy animations.
Innovation Solution
A method that adjusts rendering during user blinks by detecting gaze events to reduce processing resources, including lowering quality or preventing rendering during blinks, and reallocating those resources to other tasks or reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rendering quality is reduced during blink events, then processing resource usage is reduced, but perceptual quality of display content is maintained
Solution Approach 1:
The system dynamically adjusts rendering quality based on real-time user state detection. During blink events, the rendering quality is reduced to save processing resources, while maintaining full quality during normal viewing periods. This dynamic adaptation resolves the contradiction by making the rendering quality variable rather than fixed.
Solution Approach 2:
The system changes the rendering parameters (quality level) based on the detected blink event. By modifying the rendering quality parameter from high to low during blink events, the system optimizes processing resource usage while maintaining acceptable perceptual quality, as users cannot perceive visual changes during blinks.
2Reliability
If BVH re-building is performed at higher quality, then ray tracing performance is improved, but processing resource consumption increases
Solution Approach 1:
The system performs BVH re-building periodically rather than continuously. By timing the re-building operations to occur during blink events when processing resources are freed, the system maintains ray tracing performance without the continuous resource consumption burden. This periodic execution allows high-quality re-building when resources are available.
Solution Approach 2:
The system prepares for BVH re-building by detecting blink events in advance. When a blink is detected, the system knows that processing resources will be freed soon, so it schedules the re-building operation to occur during the blink event. This preliminary planning allows optimal timing of resource-intensive operations.
3Manufacturing precision
If rendering is performed at full quality continuously, then perceptual quality is maintained, but processing resources are wasted during blink events
Solution Approach 1:
The system uses the user's own blink behavior to automatically trigger rendering quality adjustments. The gaze tracking device detects blinks and the system responds by reducing rendering quality during those specific periods. This self-regulating mechanism ensures processing resources are not wasted on frames that will not be perceived by the user.
Solution Approach 2:
The system implements a feedback loop where gaze tracking continuously monitors user eye state and provides feedback to the rendering system. Based on this feedback about blink events, the rendering quality is dynamically adjusted. This closed-loop control ensures that processing resources are optimized based on actual user viewing behavior.

AI summary
Methods and systems for adjusting the rendering of display content by a video gaming system during gameplay are provided. A computer implemented method comprises rendering, by the video gaming system, first display content associated with the gameplay; detecting, by a gaze tracking device of the video gaming system, a blink event of a user; and in response to the detecting the blink event, adjusting, by the video gaming system, a rendering of second display content, wherein the second display content comprises display content associated with the gameplay occurring during the blink event and after display of the first display content, so as to reduce a usage of processing resources of the video gaming system in rendering the second display content.
