AR Lash Extension Guidance Using 3D Facial Landmarks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The application of artificial lash extensions requires precise placement and attachment, which is challenging due to the small size of the extensions and the limited visibility of the application area, necessitating real-time guidance and feedback for improved technique.
Innovation Solution
Implementing computer vision techniques to analyze video streams of the application process, generating 2D and 3D models of the eye area, and providing real-time augmented reality feedback through visual and auditory indicia to guide the correct placement of artificial lash extensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manual application methods are used, then the process is simple and quick to set up, but the precision and accuracy of lash extension placement is insufficient
Solution Approach 1:
The system captures real-time video of the application area, processes it through computer vision algorithms, and provides immediate visual feedback through augmented reality overlays that show the correct placement positions and orientations of lash extensions. This closed-loop feedback system enables continuous adjustment and improvement of placement precision during the application process.
Solution Approach 2:
The patent introduces an intermediary augmented reality system that acts as a mediator between the applicator and the natural lashes. This intermediary layer provides virtual guidance indicators and real-time feedback, bridging the gap between manual skill and precise placement without requiring direct complex mechanical intervention.
2Measurement precision
If the application area is magnified for better visibility, then placement accuracy improves, but the field of view and overall context are reduced
Solution Approach 1:
The system transitions from a single two-dimensional camera view to a multi-dimensional augmented reality experience by overlaying three-dimensional virtual indicators and guidance elements onto the video feed. This adds depth and contextual information without requiring physical magnification, maintaining both detail visibility and overall context.
Solution Approach 2:
The patent merges multiple information layers into a single unified view: the live video feed of the application area, the augmented reality overlay with placement indicators, and contextual guidance elements are combined into one integrated display. This allows the applicator to see both magnified details and overall context simultaneously without switching between different views.
3Manufacturing precision
If real-time video processing and analysis are implemented, then guidance accuracy is improved, but computational time and processing load increase
Solution Approach 1:
The system performs preliminary actions by pre-processing the video feed to identify key anatomical landmarks and features before the actual lash extension application begins. This preliminary segmentation and landmark detection establishes a reference framework that accelerates subsequent real-time guidance calculations and reduces processing delays during the critical placement phase.
