Fingerprint Recognition Guide Area for Touch Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices face challenges in securely recognizing fingerprints due to fragile security and potential leakage of private information, as existing fingerprint recognition methods often require precise finger placement and may not effectively guide users to achieve optimal fingerprint scans.
Innovation Solution
A method and apparatus that display a guide area adjacent to the fingerprint scan sensor, providing guide information based on the detected touch, including determining the length of the major axis of the touch area, and adjusting the touch accordingly to ensure proper fingerprint recognition, thereby improving the fingerprint recognition rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guide area is displayed adjacent to the fingerprint scan sensor, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
A guide area is displayed on the display unit adjacent to the fingerprint scan sensor to serve as an intermediary visual indicator. This guide area shows guide information (such as icons or text) that directs users on how to properly position and touch their fingers for fingerprint scanning. The guide area acts as a mediator between the system and the user, providing intuitive guidance without requiring complex instructions or interfaces.
2Measurement precision
If touch detection via the guide area is implemented, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The system detects touch inputs on the guide area and provides feedback by displaying appropriate guide information. When a user touches the guide area, the system analyzes the touch position and provides visual feedback through the display unit, guiding the user to adjust their finger placement. This feedback loop continues until the user achieves the correct touch position and pressure for successful fingerprint scanning, thereby improving measurement precision through iterative guidance.
3Reliability
If guide information is provided based on detected touch, then the reliability is improved, but the loss of time increases
Solution Approach 1:
The guide area and guide information are prepared and displayed in advance before the actual fingerprint scanning begins. The system pre-configures the guide area with relevant icons and instructions that anticipate the user's needs. By providing all necessary guidance information beforehand, the system reduces the time required during the actual scanning process, as users can immediately understand the correct positioning and touching method without delays for additional instructions.
