Gaze-Adaptive Image Display for Local High-Definition Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices generate unnecessary calculation loads due to high-definition processing when the user has no interest in observation, and fail to maintain uniform display definition when the user is interested in a specific range, leading to unnaturalness.
Innovation Solution
An image display device and method that control the display processing unit to switch between low and high content levels based on user interest, maintaining high-definition display only when the user observes a point of interest for a prescribed period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-definition image processing is performed continuously within the visual field display range, then the user can always observe detailed information, but unnecessary calculation load is generated when the user has no interest in observation
Solution Approach 1:
The patent applies local quality by differentiating the display definition across different regions of the visual field. High-definition processing is applied only to the vicinity of the observation point where the user is currently looking, while low-content level information is displayed in other areas. This spatial differentiation ensures that computational resources are allocated only where the user has interest, eliminating unnecessary calculation load while maintaining detailed display quality where needed.
2Measurement precision
If display definition is changed according to distance from the observation point, then the observation point can be displayed at high definition, but the display definition becomes non-uniform and objects do not look natural
Solution Approach 1:
The patent implements local quality by establishing a high-content level display region centered on the observation point with a predetermined radius, while maintaining low-content level display in the remainder of the visual field. This creates a clear spatial distinction that provides high definition exactly where the user is looking without creating unnatural gradients or non-uniformity across the entire display, as the transition is abrupt rather than gradual.
Solution Approach 2:
The patent segments the visual field display range into two distinct regions: a high-content level region surrounding the observation point and a low-content level region for the rest of the visual field. This segmentation allows the system to maintain uniform high-definition display within the designated high-content region while using low-content display elsewhere, avoiding the non-uniformity problem that would result from continuous definition changes based on distance.
3Loss of information
If high-quality image processing is performed when the user has no interest in observation, then detailed information is always available, but computational resources are wasted
Solution Approach 1:
The patent applies local quality by restricting high-quality image processing to the vicinity of the observation point where the user is currently looking. The system determines the observation point and establishes a high-content level display region around it, while displaying low-content level information in other areas. This ensures that detailed information is available only where the user has interest, preventing computational resource waste while maintaining information availability where needed.
Solution Approach 2:
The patent implements dynamics by making the display content level changeable based on user interest. The system dynamically switches between high-content level and low-content level display regions according to the user's observation point and gaze direction. This dynamic adaptation allows the system to allocate computational resources efficiently, providing detailed information only when the user is interested in a particular area, thereby avoiding waste of computational resources on uninterested regions.

AI summary
An image display device is for displaying an image including a user in, and includes: a display processing unit displaying an image within a user's visual field display range; and a processor controlling the entire operation including a display operation on the display processing unit. The processor controls the display processing unit such that, in a state where information is displayed at a low content level within a visual field display range by control of the display processing unit, when an observation point which a user observes closely stays within a prescribed display range for a prescribed period of time, the vicinity of the observation point is displayed as information of a high content level, whereas when the observation point has deviated: from the location of the information of the high content level, the vicinity of the observation point is returned to the information display at the low content level.
