Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin detection products require cumbersome operations and may spread bacteria due to hardware accessories, and manual selection of skin care/makeup products is inconvenient.
Innovation Solution
An interaction method for an electronic device that recognizes user gestures in real-time images to accurately determine skin states and provide suggestions, allowing for natural and intuitive skin care/makeup interactions without the need for additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If comprehensive detection on entire skin is performed, then detection accuracy is improved, but operation complexity increases as user needs to enter specified functional pages multiple times
Solution Approach 1:
The patent segments the skin detection process into multiple selectable regions (forehead, cheek, nose, chin, etc.) that users can individually choose. This allows comprehensive detection to be divided into manageable parts, reducing the complexity of operating through multiple functional pages while maintaining the ability to detect entire skin or specific areas as needed.
Solution Approach 2:
The patent implements preliminary action by allowing users to pre-select detection regions and parameters before the actual detection occurs. The system prepares detection configurations in advance based on user selections, so that when detection is initiated, the results are immediately available without requiring navigation through multiple functional pages.
2Measurement precision
If additional hardware accessory (beauty detector) is used, then detection capability is improved, but hygiene risk increases due to potential bacteria spread
Solution Approach 1:
The patent uses the device's built-in camera to capture images of the user's skin, creating a visual copy of the skin surface for analysis. This eliminates the need for physical contact with additional hardware detectors, maintaining detection capability while removing the hygiene risk associated with sharing hardware accessories between users.
Solution Approach 2:
The patent replaces the mechanical contact-based detection system (beauty detector requiring physical skin contact) with an optical detection system using the camera. This substitution eliminates the mechanical interaction that causes bacteria spread while preserving the skin analysis functionality.
3Adaptability or versatility
If manual selection of skin care/makeup products is required, then product customization is improved, but user convenience deteriorates due to inconvenient two-hand screen operation
Solution Approach 1:
The patent implements self-service by enabling users to perform skin detection and receive personalized skin care and makeup recommendations through a simplified one-handed gesture operation. The system automatically analyzes the detected skin conditions and provides customized product suggestions without requiring complex manual selection, thus maintaining product customization while greatly improving convenience.
4Loss of information
If multiple functional pages are required for viewing analysis results, then information completeness is improved, but interaction efficiency decreases
Solution Approach 1:
The patent merges multiple functional pages (skin detection results, analysis reports, care suggestions, makeup recommendations) into a single integrated display interface. All information is presented together on one screen after the user performs a simple gesture, eliminating the need to navigate through multiple pages and significantly improving interaction efficiency while maintaining information completeness.

AI summary
An interaction method for an electronic device for skin detection includes recognizing a hand action and a face of a user to determine a target hand action; determining a detection target corresponding to the hand action based on the target hand action; determining from an extended content library based on the detection target and a shape of the detection target, extended content associated with the detection target and the shape of the detection target, and outputting the extended content.
