AR Virtual Content Shape Adjustment for Distance Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) systems for vehicle navigation struggle to effectively visualize virtual content objects in a way that maintains clarity and depth perception as the distance between the user and the object changes, leading to potential distortion and reduced visibility.
Innovation Solution
A processor-implemented method that adjusts virtual content objects based on their shape projected onto a projection plane by setting reference points and axes, deforming, and rotating them to maintain a target height-to-width ratio and prevent flattening, ensuring the content remains visible and natural-looking regardless of distance, using AR glasses or head-up displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If virtual content objects are projected onto a projection plane in AR systems, then the content can be visualized on the display, but the shape and clarity of the content deteriorates when the distance between the user and the object changes
Solution Approach 1:
The patent applies dynamics by making the virtual content object's shape adjustable based on distance. The processor dynamically modifies the shape parameters of the virtual content object according to the detected distance between the user and the object, allowing the content to adapt its appearance to maintain clarity at varying distances rather than using a fixed projection.
Solution Approach 2:
The patent changes physical parameters of the virtual content object, specifically its shape parameters (height, width, aspect ratio), based on the distance from the user. By adjusting these geometric parameters dynamically, the system maintains optimal visual clarity and prevents distortion regardless of the viewing distance.
2Ease of operation
If the virtual content object is projected at a fixed shape, then the rendering process is simple, but the content becomes distorted and less visible when distance varies
Solution Approach 1:
The system transitions from static fixed-shape projection to dynamic shape adjustment. The processor continuously adapts the virtual content object's shape based on real-time distance detection, ensuring reliable visibility across varying distances while automating the complexity of shape management.
Solution Approach 2:
The patent implements feedback by detecting the distance between the user and the virtual content object, then using this information to adjust the shape parameters. This closed-loop approach ensures the content remains clearly visible by continuously adapting to changing viewing conditions.
3Reliability
If the virtual content object shape is adjusted dynamically based on distance, then visibility and clarity are maintained, but the processing complexity increases
Solution Approach 1:
The patent employs dynamic shape adjustment where the processor modifies virtual content object parameters based on detected distance. This automated dynamic process maintains reliable visibility without requiring complex manual intervention, as the system autonomously adapts the content appearance to viewing conditions.
4Ease of operation
If the virtual content object is not adjusted for distance, then the system operation is simple, but the content appears flattened and unnatural at varying distances
Solution Approach 1:
The system dynamically adjusts the shape of virtual content objects based on distance detection. This automated process maintains natural-looking content appearance by preventing flattening effects that occur with fixed projections, while the processor handles the complexity of shape management automatically.
Solution Approach 2:
The patent changes the geometric parameters (height, width, aspect ratio) of virtual content objects based on distance from the user. This parameter adjustment ensures the content maintains its natural appearance and prevents distortion, with the processor automatically managing the complexity of parameter modifications.
