AR Display Overlay Contrast Control for Scene Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality displays, informational overlays can become less readable or visible due to similar colors and textures of the displayed scene, rendering the information less useful.
Innovation Solution
An overlay module that modifies the emphasis and contrast of the informational overlay based on scene change data, object detection, and device motion, using modules such as overlay emphasis modifier and background image generator to enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the informational overlay is presented on the display, then the information is provided to the user, but the overlay becomes less readable or visible when the scene has similar color and texture
Solution Approach 1:
The patent applies color changes by dynamically adjusting the color properties of the informational overlay based on the detected scene characteristics. When the scene has certain color properties, the overlay's color is modified to create sufficient contrast and maintain readability, directly addressing the visual similarity problem between overlay and scene
Solution Approach 2:
The patent changes parameters such as brightness, contrast, and sharpness of the overlay dynamically based on scene analysis. By modifying these visual parameters in response to scene characteristics, the system maintains information readability despite variations in scene appearance
2Loss of information
If the overlay emphasis is increased to improve readability, then the information becomes more visible, but the scene details may be obscured
Solution Approach 1:
The patent applies local quality by selectively adjusting overlay properties in different regions based on scene analysis. Rather than uniformly increasing emphasis throughout the entire overlay, the system modifies specific portions of the overlay where contrast is most needed, while preserving scene visibility in other areas
Solution Approach 2:
The patent implements dynamics by making overlay emphasis adjustable and adaptive rather than fixed. The system dynamically modulates overlay properties in real-time based on scene changes, allowing the emphasis level to vary and optimize both readability and scene visibility according to current conditions
Data Source
AI summary
Example embodiments provide systems and methods for overlay contrast control in augmented reality displays. In an example method, contrast enhancement data including data describing at least a portion of a background image for presentation under an informational overlay on a display device is accessed. The informational overlay includes at least one of a graphical element or a textual element to partially obscure a scene. Data identifying at least a portion of the information overlay under which the background image is to be presented is generated. The background image is presented on a display device atop the portion of the scene corresponding to the portion of the informational overlay, and the information overlay is presented on the display device atop the background image and the scene.
