Gaze Stabilization for Display Blurriness Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image stabilization methods fail to precisely move visual data on a display screen according to the user's eye movements, leading to blurriness and a reduced viewing experience.
Innovation Solution
A method and display apparatus that utilize gaze movement-based stabilization by detecting eye movements through gaze-tracking data, determining compensatory movements, and implementing these movements using an image stabilization means to shift visual content on the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image stabilization moves visual data to remove blurriness caused by eye movements, then viewing quality improves, but the precision of movement compensation is insufficient
Solution Approach 1:
The system employs a feedback mechanism where gaze-tracking data from the user's eye movements is continuously monitored and processed. The processor receives this gaze data, determines the eye movement characteristics, and generates compensatory drive signals that are fed back to the image stabilization means. This closed-loop feedback ensures that the visual content is moved with high precision to counteract the blurriness caused by eye movements, directly resolving the contradiction between movement precision and viewing quality.
Solution Approach 2:
The patent replaces traditional mechanical image stabilization systems with a gaze-tracking based control system. Instead of relying solely on mechanical sensors to detect movement, the system uses optical gaze-tracking means to detect eye movements and converts this information into digital signals processed by a processor. This substitution enables more precise control of the image stabilization means, achieving higher movement precision while maintaining viewing experience quality.
2Reliability
If gaze-tracking data is processed to detect eye movements, then blurriness removal improves, but system complexity increases
Solution Approach 1:
The display apparatus integrates multiple functions into a unified system. The gaze-tracking means serves dual purposes: it tracks user gaze for stabilization compensation while also providing gaze data that can be used for other display optimizations. The processor handles both the gaze data processing for stabilization and the generation of drive signals for the image stabilization means. This multi-functionality approach reduces overall system complexity by consolidating functions rather than adding separate dedicated systems.
Solution Approach 2:
The patent merges the gaze-tracking system with the existing image stabilization system. Instead of treating them as separate entities, the gaze-tracking data processing is integrated directly into the control loop of the image stabilization means. The processor that handles display content also processes gaze data and generates compensatory signals. This merging reduces component count and system complexity while maintaining effective blurriness removal.

AI summary
Disclosed is a method including detecting a movement of a user's gaze by processing gaze-tracking data, collected by a gaze-tracking means of a display apparatus; when the movement of the user's gaze is detected, determining a compensatory movement which when implemented by an image stabilization means of the display apparatus, shifts visual content displayed on at least one display of the display apparatus, according to the movement of the user's gaze; and generating a first drive signal for controlling the image stabilization means to implement the compensatory movement, during a frame display time.
