AR Display Control for Virtual Object Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality applications, the visibility of virtual objects superimposed on real objects is impaired due to the real object's posture, as they often align uniformly, leading to reduced visibility and operability.
Innovation Solution
A display control device and method that determine the orientation of a real object in a real space image and select between different orientations for a virtual object to align it optimally with the real object, improving visibility by adjusting its posture based on the real object's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual objects are added to real objects in a uniform posture, then the device complexity is reduced and ease of manufacture is improved, but the visibility of the virtual object is impaired depending on the posture of the real object
Solution Approach 1:
The patent implements dynamics by making the virtual object's orientation adjustable and changeable based on the real object's detected orientation. The system dynamically selects between first and second orientations of the virtual object according to the real object's posture, transforming a static uniform display into a dynamic adaptive display that responds to real-time conditions.
Solution Approach 2:
The patent applies parameter changes by modifying the orientation parameter of the virtual object based on the detected orientation of the real object. The system changes the display parameters (orientation angles) of the virtual object to match or complement the real object's orientation, thereby optimizing visibility without requiring complex structural modifications.
2Ease of operation
If the virtual object orientation is aligned with the real object orientation, then the visibility is improved, but the system complexity increases due to orientation determination and selection requirements
Solution Approach 1:
The patent implements partial action by providing only two discrete orientation options (first and second orientations) for the virtual object rather than continuous orientation adjustment. This partial approach achieves sufficient visibility improvement for typical use cases while avoiding the complexity of full continuous orientation control systems.
Solution Approach 2:
The patent applies segmentation by dividing the virtual object's orientation into distinct segments or modes (first orientation and second orientation). This segmentation allows the system to switch between predefined orientation states based on simple detection criteria, reducing the complexity compared to continuous orientation adjustment while still achieving adaptive visibility optimization.
