AR False Eyelash Preview With Precise Lash Underside Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for previewing false eyelashes are costly and time-consuming, and existing systems lack precision in sizing, locating, and orienting virtual beauty products, particularly on small facial features like the eyelid or underside of natural lashes, leading to deficiencies in realism and accuracy.
Innovation Solution
Utilizing computer vision techniques to generate an augmented reality (AR) environment that tracks points on a subject's face and positions a 3D model of false eyelashes accurately, adjusting for location, orientation, and scale in real-time based on facial movements.

Engineering Contradiction Analysis
1Productivity
If conventional methods are used to preview false eyelashes, then the process is simple, but it is costly and time-consuming
Solution Approach 1:
The patent creates a virtual copy of the false eyelashes as a 3D model that can be overlaid onto the user's eye area in real-time through AR technology. This virtual copy allows users to preview the appearance, sizing, and positioning of false eyelashes without physical application, eliminating the need for costly and time-consuming in-person consultations and physical trial applications.
Solution Approach 2:
The patent replaces the mechanical system of physical eyelash application with an optical/digital system using AR overlays and computer vision. Instead of physically applying lashes to the user's eye, the system uses camera capture, 3D rendering, and augmented reality display to simulate the appearance, dramatically reducing time and cost while maintaining preview accuracy.
2Measurement precision
If existing systems are used to position virtual beauty products, then the implementation is straightforward, but precision in sizing, locating, and orienting is insufficient
Solution Approach 1:
The patent segments the eyelash positioning task into multiple independent components: eye area detection through computer vision, 3D model generation, virtual eyelash placement, and real-time rendering. This segmentation allows each component to be optimized independently, achieving high positioning precision through coordinated operation of multiple specialized modules rather than a single complex system.
Solution Approach 2:
The patent utilizes parameter changes in the AR system to achieve precise positioning. By dynamically adjusting parameters such as scale, orientation, and position of the 3D eyelash model based on real-time computer vision data from the user's eye area, the system achieves accurate sizing and positioning without requiring overly complex hardware or algorithms.

AI summary
A first computer vision operation is performed on a first video segment of a video stream to track points corresponding to an underside of natural eyelashes of an eye area of a subject. The first video segment is modified to include a first overlay of a first model of a first artificial lash extension positioned at least at a first point of the points corresponding to the underside of the natural eyelashes. The first modified video segment is provided for presentation at a client device associated with the subject.
