Electronic Device Fingerprint Registration With Visual Progress Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in efficiently registering fingerprints due to incorrect finger placement, leading to frequent misrecognition and lack of clear feedback on registration progress, which affects security and efficiency.
Innovation Solution
The electronic device provides real-time feedback on fingerprint registration progress through display attributes and guide messages, distinguishing overlapping and non-overlapping fingerprint areas, and synthesizing clear images for accurate registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electronic device displays an execution screen irrelevant to fingerprint registration, then the device complexity is reduced, but the user cannot identify whether the fingerprint is properly registered or how clearly the actual fingerprint is registered
Solution Approach 1:
The patent applies color changes to display attributes of fingerprint images to indicate registration progress and quality. Different display attributes (such as color intensity, transparency, or highlighting) are used to show which parts of the fingerprint have been successfully captured and which parts need additional input, providing visual feedback without complicating the overall display system.
Solution Approach 2:
The patent implements feedback by displaying the captured fingerprint image and its display attributes back to the user during registration. This allows users to see the registration progress in real-time and understand whether their fingerprint placement is correct, enabling them to adjust and re-input if necessary.
2Ease of operation
If the electronic device does not provide guide information beyond failure messages, then the ease of operation is improved, but the productivity of fingerprint registration is reduced due to repeated incorrect attempts
Solution Approach 1:
The system provides continuous feedback during the registration process by displaying the captured fingerprint image and using display attributes to indicate success or failure of specific fingerprint regions. This guides users to adjust their finger placement without requiring complex instructional interfaces, maintaining simplicity while improving efficiency.
Solution Approach 2:
The patent performs preliminary analysis of the captured fingerprint image and determines whether the capture is successful before proceeding. This preliminary action allows the system to provide immediate, targeted feedback to users, preventing repeated unsuccessful attempts and improving registration efficiency without adding operational complexity.
3Reliability
If the electronic device requires multiple sequential fingerprint inputs without progress feedback, then the reliability of fingerprint registration is improved, but the loss of time increases due to lack of user guidance
Solution Approach 1:
The patent provides real-time feedback during multi-step fingerprint registration by displaying captured images and using display attributes to show progress. Users can see which fingerprint regions have been successfully captured and which need additional inputs, reducing unnecessary repeated attempts and time loss while maintaining registration reliability.
Solution Approach 2:
The system dynamically adjusts the registration process based on real-time feedback. If a fingerprint capture is successful, the system progresses to the next region; if unsuccessful, it provides targeted feedback for correction. This dynamic approach optimizes the registration time while ensuring reliable capture of all necessary fingerprint regions.

AI summary
An electronic device includes: a fingerprint input unit located in one area of the electronic device to receive a fingerprint of a user; and a controller configured to control a display unit to display information on a fingerprint registration progress situation in correspondence to a plurality of fingerprints that are sequentially input to the fingerprint input unit, determine whether a fingerprint of the user is to be registered according to the fingerprint registration progress situation information, and register a fingerprint of the user by using at least some of the plurality of fingerprints. A fingerprint registration progress situation can be identified when a fingerprint is registered.
