AR HUD Content Depth Adjustment for Object Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality (AR) systems for vehicle navigation struggle to effectively visualize content in a 3D space without causing visual fatigue or overlap with real-world objects, particularly when objects move or change lanes, leading to unnatural image recognition and potential crosstalk.
Innovation Solution
A content visualizing device equipped with an object detector and processor that adjusts the depth, position, size, and shape of displayed content based on distance and movement of objects, using a head-up display (HUD) to create a natural and non-overlapping 3D graphic representation by limiting depth and dynamically changing visualized content in response to vehicle and object movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is displayed at a fixed position in AR-based HUD, then the navigation information is consistently visible, but it may overlap with real-world objects causing visual fatigue and unnatural image recognition
Solution Approach 1:
The patent applies dynamics by making the content display position and depth adjustable rather than fixed. The processor dynamically changes the depth and position of displayed content based on real-time object detection results, allowing the system to adapt to moving objects and prevent overlap while maintaining navigation information visibility.
Solution Approach 2:
The patent changes display parameters (depth and position) based on object distance. When an object is detected within a threshold distance, the system modifies the depth parameter to place content behind the object, and adjusts position parameters to avoid overlap, thereby eliminating visual fatigue while preserving information visibility.
2Shape
If content depth is increased to improve 3D visualization, then the spatial representation is more natural, but content may overlap with distant objects causing crosstalk
Solution Approach 1:
The system uses feedback from the object detector to continuously monitor object positions and distances. Based on this feedback, the processor adjusts content depth in real-time, ensuring that even when content is displayed with 3D spatial representation, it does not overlap with detected objects, thereby preventing crosstalk while maintaining natural spatial visualization.
3Reliability
If the system dynamically adjusts content position and depth based on object movement, then overlap with objects is prevented, but the system complexity increases
Solution Approach 1:
The patent applies local quality by adjusting display parameters only in the specific region where objects are detected. Rather than continuously modifying the entire display, the system selectively changes depth and position parameters for content that may overlap with detected objects, thereby preventing overlap while minimizing unnecessary system complexity.
4Device complexity
If content is displayed with fixed depth, then the display system is simpler, but it causes visual fatigue when objects move closer or farther
Solution Approach 1:
The patent implements dynamics by making the content depth adjustable based on object distance. When objects are detected, the system dynamically modifies the depth parameter to maintain appropriate visual spacing, preventing visual fatigue caused by fixed-depth display issues while keeping the overall system relatively simple through targeted parameter adjustments.
