The attempt to influence the shopping behavior of customers in a supermarket through music often fails due to the different music preferences. In this work, a method to bring personalized music in the supermarket is presented by providing a location-aware playback and notification service. By using a web interface, customers are able to create an electronic shopping list, associate list items with music tracks, and thus create an individual shopping playlist. These product-associated music tracks start playing at the customer’s instrumented shopping cart when he enters specific product departments where an item from the shopping list is located. Additionally, a service to provide product-awareness through non-speech audio cues is presented. This location-aware service notifies customers when they come closer to products that are listed on their shopping list. A two-stage notification approach is used to create user-centric notification zones. Depending on the customer’s distance to the product, he gets notified by an ambient or arousal noise that is mixed into the background music. In addition, further information about the detected product is displayed on the screen that is mounted at our instrumented shopping cart.
