Wireless Device Camera RDV for Intuitive Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless device connection methods, such as DLNA/UPnP, are complex and not intuitive for users to share or connect devices within a home network environment.
Innovation Solution
A method and apparatus that utilize a camera in a wireless device to capture an image of a counterpart device, determine a Relative Distance Value (RDV) based on the shooting distance, and use this value along with auxiliary information as a unique identification factor to connect devices within the same network environment for functions like image view, multimedia play, data backup, and data sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If DLNA/UPnP procedures are used for device connection, then device sharing functionality is achieved, but the connection process becomes complex and non-intuitive for users
Solution Approach 1:
The patent replaces manual configuration procedures with optical recognition. The camera captures an image of the counterpart device, and image processing automatically extracts connection information, substituting the mechanical/manual DLNA/UPnP setup process with an optical recognition system that intuitively identifies and connects devices
Solution Approach 2:
The patent uses image capture to create a visual copy of the counterpart device. This captured image serves as the basis for automatic device identification and connection, eliminating the need for users to manually navigate complex connection procedures while maintaining accurate device pairing
2Measurement precision
If additional hardware is added to improve device detection accuracy, then detection precision improves, but device complexity and cost increase
Solution Approach 1:
The patent makes the existing camera serve multiple functions: it is used both for normal photography and for device detection and identification. By processing the captured image to extract device characteristics and calculate RDV, the system achieves accurate device detection without adding specialized hardware, leveraging the universal capability of the camera across different functions
Solution Approach 2:
The system uses the wireless device's own camera and processing capabilities to perform device detection and identification. The device serves itself by capturing images, processing them through image analysis algorithms, and automatically determining connection parameters without requiring external detection hardware or additional specialized components
Data Source
AI summary
An apparatus and a method detect and connect a counterpart device by capturing an image of the counterpart device in a wireless device. A Relative Distance Value (RDV) between the wireless device and the counterpart device is determined via image capture using a camera. The counterpart device is identified using the determined RDV.
