AR Display Glare Reduction via Targeted Enhancement Graphics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality systems primarily focus on displaying information in the peripheral view, but there is a need to alter the appearance of selected objects in a user's field of vision to enhance their experience, such as reducing glare from bright objects like headlights or the sun, which existing systems do not effectively address.
Innovation Solution
An apparatus and method that identify target objects within a user's field of vision and display enhancement graphics superimposed on these objects using identification and enhancement logic, which includes analyzing image information, defining detection regions, and applying transformation mappings to position the graphics correctly on the display, allowing for semi-transparent glare-reducing graphics to be displayed over bright objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If augmented reality displays project graphics on transparent display to enhance user view, then information display capability is improved, but glare from bright objects like headlights or sun cannot be effectively reduced
Solution Approach 1:
The system dynamically changes the optical properties of the transparent display by projecting glare-reducing graphics with specific color characteristics (e.g., cyan, magenta, yellow) over bright objects. These colored projections reduce the intensity of harmful glare while maintaining the transparency and information display functionality of the augmented reality system.
Solution Approach 2:
The patent introduces an intermediary component - the glare-reducing graphic projection - that acts as a mediator between the bright objects (headlights, sun) and the user's eyes. This intermediary layer filters and reduces the harmful glare while allowing the augmented reality information to remain visible through the transparent display.
2Area of stationary object
If graphics are displayed around the periphery of user's field of vision to avoid obstruction, then main field of vision remains clear, but objects in the center of vision cannot be enhanced or have glare reduced
Solution Approach 1:
The system transitions from two-dimensional peripheral graphics to three-dimensional spatial projection by overlaying glare-reducing graphics directly onto objects in the central field of vision. This dimensional extension allows the display to address harmful factors in the previously unreachable central viewing area while maintaining peripheral information display capabilities.
Solution Approach 2:
The patent applies different display qualities to different regions of the field of vision. Glare-reducing graphics with specific optical properties are projected locally onto bright objects in the central field, while peripheral areas maintain their information display function. This localized application of different display characteristics resolves the contradiction between peripheral display area and central vision enhancement.

AI summary
Systems, methods, and other embodiments associated with enhancing an augmented reality display are described. According to one embodiment, a method for enhancing an augmented reality display includes identifying, within an image of a viewing region, a target object visible to a user through a display; and displaying an enhancement graphic on the display such that the enhancement graphic is superimposed over the target object from the user's point of view.
