Semi-Transparent Mirror Spacing for AR Styling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mirror-type augmented reality systems face challenges in usability and convenience, particularly in applications like user styling, where existing technologies struggle to effectively integrate virtual and real-world images for users.
Innovation Solution
A device comprising a sensing unit, a semi-transparent mirror unit, and a display unit, where the semi-transparent mirror unit is spaced apart from the display unit by a critical distance determined based on the user's pupil size, allowing for the reflection and transmission of light to overlay virtual images onto the real-world view, enabling users to see both actual and virtual images simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mirror-type augmented reality system is used for user styling, then it is more suitable for appearance styling applications, but usability and convenience need improvement
Solution Approach 1:
The patent applies parameter changes by adjusting the spacing between the semi-transparent mirror unit and display unit based on optical parameters (critical distance related to pupil size). This optimization enables users to clearly see both real and virtual images simultaneously without frequent focus adjustments, thereby improving usability while maintaining suitability for styling applications
2Adaptability or versatility
If virtual images are overlaid onto real-world view, then user styling capability is enhanced, but focus adjustment frequency increases
Solution Approach 1:
The patent optimizes the spacing parameter between the semi-transparent mirror unit and display unit to be within a specific range (equal to or longer than a first distance and equal to or shorter than a second distance). This parameter optimization allows both real and virtual images to be in focus simultaneously, eliminating the need for frequent focus adjustments and reducing time loss
Solution Approach 2:
The semi-transparent mirror unit acts as an intermediary that enables simultaneous viewing of real-world images and virtual images at optimized spacing distances, allowing users to try various styles without focus adjustment interruptions
3Measurement precision
If the semi-transparent mirror unit and display unit are spaced apart by critical distance, then clear focused view is achieved, but device complexity increases
Solution Approach 1:
The patent determines the spacing between the semi-transparent mirror unit and display unit based on optical parameters (critical distance related to pupil size). By optimizing this spacing parameter, the system achieves clear focused viewing of both real and virtual images simultaneously. The complexity is managed by providing specific spacing guidelines rather than requiring complex active adjustment mechanisms
