One of Tesco's stores is running an experiment with a sat-nav like system, based off wi-fi nodes to triangulate position in-store
The new service is able to show you where all your wanted products are on a store map, show you where you are on that map, and guide you round the store to pick up your products using the shortest route.
The prototype system is installed at the Tesco Extra, Romford (Gallows Corner) in north-east London, and we need to recruit a large control group of customers (including staff) who would like to try it out on their Android smart-phones.
