RetailNext: In-store Shopping Patterns
This heat map might seem a bit unimpressive at first, as it looks like a big color blotch. It's showing the movements of actual customers in a retail store aisle, though. Red areas represent the spots where most customers shop.
Retailers can use the heat map for product placements and to see whether a sales campaign was successful. RetailNext pulls the data from video cameras in the store, Wi-Fi networks and other sensors in the store that track customer movement.
