Augmented Reality Virtual Object Opacity Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In head-mounted display systems, overlapping virtual objects and objects extending beyond the display area can cause confusion and make it difficult for users to view both simultaneously, while poor visibility due to background lighting conditions further complicates the interaction with augmented reality environments.
Innovation Solution
The system modifies the appearance of virtual objects by fading or altering their opacity based on priority levels and edge detection, applying gradient alpha borders, and adjusting brightness to enhance visibility, thereby directing user attention and indicating additional content beyond the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple virtual objects are displayed simultaneously in augmented reality, then information completeness is improved, but visual clarity deteriorates due to overlapping objects
Solution Approach 1:
The patent applies opacity modifications to virtual objects based on their priority levels and overlap relationships. When objects overlap, the system adjusts their transparency levels to create visual hierarchy, allowing users to distinguish between multiple simultaneous objects while maintaining information completeness
Solution Approach 2:
The system dynamically changes the opacity parameter of virtual objects based on priority levels and spatial relationships. By modifying this visual parameter in real-time, the system maintains clarity when multiple objects are displayed simultaneously without reducing the quantity of information presented
2Quantity of substance
If virtual objects extend beyond display area to provide complete information, then information completeness is improved, but visibility deteriorates at edges
Solution Approach 1:
The patent applies gradient alpha borders that create varying opacity levels across different regions of virtual objects. Edges have different transparency properties than centers, allowing objects to extend beyond the display area while maintaining visibility through localized quality variations in the border regions
3Difficulty of detecting and measuring
If virtual objects are made opaque to improve visibility, then visibility is improved, but overlap confusion worsens
Solution Approach 1:
The system uses opacity adjustments as a visual differentiation mechanism. By varying the transparency levels of overlapping objects based on their priority levels, the system maintains visibility of all objects while reducing confusion through clear visual hierarchy
Solution Approach 2:
The opacity of virtual objects is dynamically adjusted based on real-time overlap detection and priority level comparisons. This dynamic modification allows the system to adapt to changing spatial relationships and maintain both visibility and clarity throughout interaction

AI summary
A method, an electronic device, and computer readable medium is provided. The method includes identifying a plurality of virtual objects for output to a display of the electronic device, including a priority level for each of the plurality of virtual objects. The method also includes comparing the priority level of an object of the plurality of virtual objects to the priority level associated with another object of the plurality of virtual objects to determine whether to modify an appearance of either object. In response to determining to modify the appearance of either object, the method further includes modifying the appearance of either. The method additionally includes rendering the plurality of virtual objects on the display of the electronic device.
