Facial Recognition Device Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for establishing connections between electronic devices are cumbersome, requiring users to manually select devices and often necessitate additional identification steps, which can discourage users from communicating with other devices.
Innovation Solution
An electronic device captures an image of a target person associated with the target device and recognizes facial features to establish a connection, using image and speech recognition to simplify the pairing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pairing methods are used to establish connection between electronic devices, then connection reliability is improved, but operation complexity increases and user convenience deteriorates
Solution Approach 1:
The patent replaces manual mechanical operations (device selection, code entry) with biometric authentication (facial recognition). The system captures images of the user's face, extracts facial features, and automatically establishes connections without requiring users to navigate device lists or enter pairing codes, thus maintaining connection reliability while dramatically improving ease of operation
Solution Approach 2:
The system performs automatic device pairing through facial recognition without requiring user intervention in the pairing process. Once the user's face is captured and recognized, the system automatically identifies available devices and establishes connections, allowing the system to serve itself rather than requiring manual user operations
2Reliability
If manual device selection and identification code entry are required, then connection security is improved, but time consumption increases
Solution Approach 1:
The system performs preliminary facial feature extraction and stores biometric data before the actual connection is needed. When connection is required, the pre-extracted facial features are quickly matched against stored data, enabling rapid authentication without real-time manual code entry, thus reducing pairing time while maintaining security
Solution Approach 2:
The patent substitutes time-consuming manual code entry with rapid biometric verification. Facial recognition provides both security verification and speed, as the system can quickly capture and process facial images compared to the sequential steps of manual device selection and code input
3Measurement precision
If detailed device information is provided in the device list, then device identification accuracy is improved, but information complexity increases
Solution Approach 1:
The patent extracts only the essential identifying feature (facial biometric data) from the complex device information set. Instead of presenting users with detailed device lists containing multiple attributes, the system extracts and uses only the critical facial recognition data for device identification, reducing information complexity while maintaining identification accuracy

AI summary
A method, performed in an electronic device, for connecting to a target device is disclosed. The method includes capturing an image including a face of a target person associated with the target device and recognizing an indication of the target person. The indication of the target person may be a pointing object, a speech command, and/or any suitable input command. The face of the target person in the image is detected based on the indication and at least one facial feature of the face in the image is extracted. Based on the at least one facial feature, the electronic device is connected to the target device.
