Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting electronic devices to external display devices, such as AR glasses, require users to manually input passcodes, which is inconvenient and may compromise security.
Innovation Solution
An electronic device equipped with a camera, communication circuitry, and memory, which performs face authentication and displays an authentication code for the external display device, allowing for secure and simplified connection using biometric information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual passcode input is used for connection, then connection security can be maintained, but user convenience and connection speed deteriorate
Solution Approach 1:
The system performs automatic face recognition and authentication without requiring manual passcode input. The electronic device autonomously captures facial images, compares them with stored biometric data, and establishes connection based on recognition results, eliminating the need for user intervention in the authentication process
Solution Approach 2:
The patent replaces the manual mechanical action of typing passcodes with an automated optical recognition system. The camera captures facial images and the processor automatically compares them with stored biometric information, substituting manual input with automated image processing and recognition
2Reliability
If face authentication is implemented, then connection security is improved, but device complexity increases
Solution Approach 1:
The camera module serves multiple functions: it captures images for face authentication, displays visual feedback to users, and can capture images for other device functions. This multi-functionality reduces the need for separate dedicated components for each function
Solution Approach 2:
The system uses stored facial image data as a reference copy to compare against live captured images. Instead of requiring complex real-time verification systems, the patent uses pre-stored biometric templates for pattern matching and authentication decisions
3Productivity
If biometric authentication is used, then connection speed is improved, but measurement precision requirements increase
Solution Approach 1:
The system pre-processes and stores facial image data during initial setup or previous interactions. By having pre-stored biometric templates ready for comparison, the system can perform rapid authentication without requiring complex real-time analysis, thus achieving both speed and accuracy
Solution Approach 2:
The system provides visual feedback through the display showing authentication status and progress. This feedback mechanism allows the system to adjust processing parameters in real-time, ensuring accurate recognition while maintaining fast connection speeds by stopping processing once sufficient confidence is achieved
