Store Product Gaze Detection Using Segmented Camera Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for collecting information about customer interactions with products in stores, such as using cameras, face challenges in accurately determining which products are being looked at by customers due to insufficient camera coverage, leading to inaccurate data collection and potential duplication of customer information.
Innovation Solution
An information collection system with multiple devices installed near each product type, equipped with image pickup and communication functions, collects and processes information associated with customers and products, allowing for accurate identification of product interest and reducing duplicate data collection by ensuring each customer is linked to the correct product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the number of cameras is smaller than the number of product types, then the device complexity is reduced, but the measurement precision of product gaze estimation deteriorates
Solution Approach 1:
The system segments the store environment by assigning dedicated cameras to specific product types or display shelves. Each camera is responsible for monitoring a particular product category, creating discrete observation zones that enable accurate product-gaze mapping without requiring comprehensive coverage of all products.
Solution Approach 2:
Instead of using uniform camera placement throughout the store, the system implements local quality by positioning cameras specifically at display shelves or product types where gaze estimation is most critical. This localized approach concentrates measurement resources where they are most needed for accurate product identification.
2Measurement precision
If cameras are installed at every display shelf, then the measurement precision of customer interaction data is improved, but the device complexity and cost increase
Solution Approach 1:
The system applies partial action by installing cameras only at selected display shelves or product types rather than universally at all locations. This selective deployment achieves sufficient measurement precision for the intended analysis while avoiding the excessive complexity and cost of full coverage.
Solution Approach 2:
Cameras installed at strategic locations serve multiple functions: they capture customer gaze direction, identify products of interest, and track customer movement patterns. This multi-functionality allows the system to achieve high measurement precision without proportionally increasing the number of cameras.
3Measurement precision
If multiple cameras are used to cover all product types, then the measurement precision is improved, but the loss of information due to duplicate customer data increases
Solution Approach 1:
The system segments the monitoring responsibility by assigning specific cameras to specific product types or display zones. This segmentation creates clear boundaries for data collection, allowing the system to distinguish between customers viewed by different cameras and accurately attribute interactions to the correct product types, thereby reducing duplicate information.
Solution Approach 2:
The system incorporates feedback mechanisms that track which customers have already been recorded by which cameras. When a customer is detected by multiple cameras, the system uses feedback information to identify and exclude duplicate records, maintaining measurement precision while preventing information loss through redundant data.
