Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user recognition systems require intentional user actions, such as fingerprint registration, which can be frustrating and may not work well due to poor capturing, leading to a desire for a method that achieves recognition without needing the user to perform any intentional step.
Innovation Solution
A system and method using a remote controller unit with a fingerprint sensor integrated into the navigation keypad area, capturing fingerprint frames during normal use, such as navigating TV content, and transmitting these to a computing device or mobile device for user identification, allowing recognition without explicit registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fingerprint sensor is used for user recognition, then user identification accuracy is improved, but the user experience deteriorates due to requiring intentional registration actions
Solution Approach 1:
The system performs fingerprint capture in advance during normal navigation operations. The fingerprint sensor continuously captures fingerprint images when the user navigates through content, before explicit registration is required. This preliminary capture of biometric data during routine interactions eliminates the need for separate registration steps while maintaining identification accuracy.
Solution Approach 2:
The system enables automatic fingerprint capture and processing without requiring user intervention. The fingerprint sensor automatically detects and captures fingerprint images during navigation, and the system autonomously processes these images for user identification. This self-service approach removes the burden of intentional registration actions from the user while maintaining precise user recognition.
2Reliability
If traditional fingerprint registration is implemented, then user recognition capability is achieved, but time consumption increases due to repeated registration attempts
Solution Approach 1:
The fingerprint sensor operates continuously during navigation operations, capturing fingerprint images throughout the user's interaction with the system. This continuous capture ensures that sufficient fingerprint data is collected during normal use, eliminating the need for repeated registration attempts and reducing the time required to achieve reliable user recognition.
Solution Approach 2:
The system performs fingerprint data collection in advance during routine navigation tasks. By continuously capturing fingerprint images while the user navigates through content, the system accumulates sufficient biometric data before explicit registration is needed, thereby reducing registration time while maintaining recognition reliability.
3Measurement precision
If a separate registration process is used, then biometric data capture is ensured, but device complexity increases
Solution Approach 1:
The fingerprint sensor serves multiple functions: it acts as both a navigation input device and a biometric data capture device. During normal navigation operations, the sensor simultaneously captures fingerprint images while enabling cursor movement or item selection. This multi-functionality ensures accurate biometric data capture without requiring a separate registration process, thereby reducing system complexity.
Solution Approach 2:
The system merges the navigation control function and fingerprint capture function into a single integrated process. The fingerprint sensor is used for both navigating through content and collecting biometric data, combining what were previously separate operations into one unified interaction mode. This merging eliminates the need for separate registration procedures while maintaining precise biometric data capture.
