The Shopper Tracker is one of those devices that does exactly what its name suggests -- and so much more. Developed by Argentina's Agile Route, this Kinect hack uses an array of heat sensors and 3D spatial recognition software to track a consumer's movements and behavior within any brick and mortar retail outlet. These data can then be used by a store owner to find out which shelves and items are appealing to customers, effectively adding a Google Analytics-like dimension to their product displays. The system is also capable of tracking multiple people at once, and can even provide feedback on which products consumers actually pull from the shelves. According to the company, this type of analysis can result in obvious strategic benefits for merchants, while reminding the rest of us that we're totally predictable. Check it out in action, after the break.
