One of the core considerations when developing promotional displays to boost sales is the progression of the shopper's gaze. What is the first thing a customer looks at in the store, what are the most effective measures to lure that gaze to a given product, and what's the best way to achieve maximum attention? One method for gathering this information is an eye-tracking system that accompanies the customer on their way through the supermarket. Customers can try it out for themselves at the STI Group's trade fair stand and receive a video of "their" shopping trip after the trade fair. "The use of the eye-tracking system is intended to give our customers insights into the shopper and show how this kind of information can be used in designing sales promotion instruments," says Norman Thom, Managing Director of STI POS Solutions.
