Camera-Based Device Identification for IoT Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data sharing methods between electronic devices, especially in IoT environments, face challenges such as the need for pre-registration on sharing servers and inconvenient initial connection procedures in short-range wireless networks, limiting flexibility and convenience in sharing data without physical contact or complex procedures.
Innovation Solution
An electronic device method that determines the location of other devices for data sharing using a camera's angle of view and focal length, transmitting signals for identification and data transfer, and employs beamforming and power control to selectively share data with devices within a defined range, providing an intuitive user interface for creating and managing sharing groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data sharing is conducted via a sharing server on the Internet, then data can be shared between devices, but pre-registration is required which limits flexibility and convenience
Solution Approach 1:
The patent applies preliminary action by performing device identification and sharing group creation before actual data transfer. The transmitting device identifies other devices in advance using camera-based recognition, pre-establishes sharing groups, and prepares transmission parameters beforehand. This eliminates the need for pre-registration on servers while maintaining flexible adaptability to different sharing scenarios.
2Adaptability or versatility
If short-range wireless network is used for data sharing, then pre-registration is not needed, but complex initial connection procedures are required
Solution Approach 1:
The patent replaces manual mechanical operations (physical NFC contact, PIN code input, manual device selection) with optical recognition technology. The camera captures images of other devices, automatically identifies them through image processing, and establishes connections without user intervention. This substitution dramatically simplifies the connection procedure while maintaining the flexibility of short-range wireless sharing.
3Ease of operation
If NFC tagging or PIN sharing is used to simplify connection, then physical contact or manual input is required, but this reduces convenience
Solution Approach 1:
The patent replaces mechanical contact methods (NFC physical contact) and manual input methods (PIN sharing) with non-contact optical recognition. The camera-based identification system captures device information visually, processes it automatically, and establishes connections without requiring physical contact or manual keyboard input. This eliminates the harmful factors of physical contact requirements and manual input complexity.
