Aimed to give consumers more information about the food products they are buying (such as their carbon footprint and where they were produced), while minimizing packaging, FoodTracer is a bright idea on how AR can make the world a tad better. Users would be able to access the information that concerns them, compare and bookmark several products, and later examine their shopping history at home. Here's one of Costanza's imagined use cases:
When Susan goes shopping in her usual supermarket she knows where organic products are placed so she can quickly pick the right products, but today she went shopping in a new supermarket where products are displayed in a different way, she doesn't have the time to check on the packaging which product is organic so she uses FoodTracer to easily spot organic apples.Costanza even built a demo application for the Symbian mobile operating system, using embeded markers and d-touch nice looking markers that hide in the products' logos, as can be seen in the following video:
