Linking Devices via Camera Movement Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communicating devices often struggle to accurately identify and link with each other in close proximity due to limitations in tracking systems and inaccurate signal strength estimates, especially when devices have similar appearances or are disguised by cases, leading to restricted functionality and inaccurate location determination.
Innovation Solution
A computer-implemented method and system that uses live camera data to identify and link communicating devices by determining visible movement and matching it with video movement from connected devices, allowing for accurate location determination and merging of data to form a single device record.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional tracking systems are used to identify devices in close proximity, then device identification can be performed, but accuracy deteriorates when devices have similar appearances or are disguised by cases
Solution Approach 1:
The patent replaces traditional mechanical tracking systems with optical-based camera imaging to identify and link devices. The linking device uses its camera to capture images of visible devices, and connected devices provide their camera data to determine relative positions and movements, substituting mechanical tracking with optical detection methods that are not affected by device appearance or cases.
2Measurement precision
If signal strength estimates are used to determine device locations, then location information can be obtained, but accuracy deteriorates in close proximity scenarios
Solution Approach 1:
The patent substitutes signal strength-based location estimation with camera-based visual detection. The linking device captures images of visible devices, and connected devices provide their camera data to calculate relative positions and movements, replacing electromagnetic signal measurements with optical imaging that provides accurate spatial information in close proximity.
3Measurement precision
If camera data from multiple devices is collected and processed, then accurate relative position determination is achieved, but system complexity increases
Solution Approach 1:
The patent divides the device identification and positioning system into distinct functional segments: the linking device that captures visible device images, connected devices that provide their camera data, and processing components that match movements and determine relative positions. This segmentation allows complex functionality to be distributed across multiple devices, managing system complexity through modular architecture.
Solution Approach 2:
The patent introduces an intermediary processing mechanism that receives camera data from multiple devices, calculates relative movements, and matches them to identify corresponding devices. This intermediary layer coordinates the interaction between linking and connected devices, managing the complexity of multi-device data collection and processing through centralized coordination.

AI summary
A method, system, and computer program product for identifying and linking communicating devices using live camera data includes: identifying a visible device that is visible to a linking device; identifying a connected device that is connected to the linking device; determining visible movement of the visible device; requesting video information from the connected device; calculating, using the video information, video movement of the connected device; determining that the visible movement matches the video movement; concluding, based on the determining, that the visible device is the connected device; and linking, based on the concluding, the visible device and the connected device.
