Mirror Display Depth Control for AR Visual Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mirror displays in augmented reality systems often cause visual discomfort due to mismatched depth perspectives between the reflected mirror image and displayed objects, leading to decreased immersion and understanding.
Innovation Solution
A mirror display system incorporating a sensor module and control circuit to determine the incident angle and distance between a subject and the mirror, calculating a depth value and displaying objects with corresponding depth to match the mirror image's perspective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mirror display simultaneously displays a mirror image and a computer-generated object, then augmented reality information is provided to the user, but visual discomfort occurs due to depth mismatch between the mirror image and the object
Solution Approach 1:
The patent changes the depth parameter of the computer-generated object to match the depth of the mirror image. The control circuit adjusts the depth value of the object based on the distance between the subject and the mirror display, ensuring that the object's depth corresponds to the mirror image's depth, thereby eliminating visual discomfort while maintaining augmented reality functionality
Solution Approach 2:
The patent implements a feedback mechanism where the sensor module detects the subject's distance from the mirror display, and this information is fed back to the control circuit. The control circuit then adjusts the object's depth parameter based on this feedback, creating a closed-loop system that dynamically matches the object's depth to the mirror image's depth to prevent visual discomfort
2Ease of operation
If the depth of the displayed object is fixed, then the display system is simple to control, but the user experiences visual discomfort due to perspective mismatch with the mirror image
Solution Approach 1:
The patent transitions from a static depth value to a dynamic depth value that changes based on the subject's distance from the mirror display. The control circuit continuously adjusts the object's depth parameter in response to changes in the subject-mirror display distance, ensuring that the depth perspective remains accurate and matched to the mirror image while maintaining relatively simple control through automated adjustment
