Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively associate RFID tracking data with video-based behavior and demographic analysis in retail environments, lacking integration with transaction data and requiring extensive hardware installations for image capture, which is costly and impractical.
Innovation Solution
A method and system that combines RFID data with video-based behavior and segmentation data using computer vision technologies for automatic behavior analysis, demographic composition analysis, and transaction data, reducing the need for extensive image capture hardware by using passive RFID tags and selected camera installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If RFID technology is used for tracking customers in a retail environment, then customer location and movement data can be collected, but the system lacks integration with video-based behavior and demographic analysis capabilities
Solution Approach 1:
The patent combines RFID tracking data with video-based behavior analysis and demographic segmentation data into a unified system. The RFID readers capture customer location and movement information, while video cameras capture behavioral data, and both are integrated through a processing system that correlates the data streams to provide comprehensive shopping behavior analysis.
Solution Approach 2:
The system performs multiple functions: RFID tracking for location data, video capture for behavior analysis, demographic segmentation for customer profiling, and transaction data integration for purchase pattern analysis. This multi-functional approach allows a single system to provide comprehensive insights into customer shopping behavior across multiple dimensions.
2Measurement precision
If extensive video capture hardware is installed throughout the store for comprehensive behavior analysis, then detailed shopper behavior data can be collected, but the hardware cost and system complexity increase significantly
Solution Approach 1:
The system divides the store into multiple zones with RFID readers positioned at strategic locations rather than requiring continuous video coverage throughout. Video cameras are placed at key decision points and high-value product areas, while RFID technology provides tracking coverage in intervening spaces, segmenting the monitoring approach to reduce overall hardware requirements.
Solution Approach 2:
RFID technology serves as an intermediary between limited video capture points, providing continuous tracking data that bridges gaps where video cameras are not installed. This allows the system to maintain comprehensive customer tracking without requiring video hardware in every location, reducing overall system complexity.
