The project and the problem
A retailer wanted to understand how shoppers moved through a physical store and which shelf areas attracted attention before a purchase, without identifying individuals. Sales records showed only the final transaction, while people counting and person detection could not reveal what someone looked at. An ordinary store camera also provided no reliable training label for the shopper's true gaze direction.
How the process worked
The store was mapped into a shared coordinate system and anonymous camera tracks were localized within it. During model development, eye-tracking glasses supplied the missing gaze ground truth, linking camera imagery, shopper position and the shelf actually viewed; deployment then required only the ordinary camera feed to estimate shelf-attention events.
