The supermarket navigation system is designed to assist shoppers in selecting heart-healthy foods and learning how to prepare healthier meals. There are three parts in the system: the shopping guide, the meal cards and the shopping list. The shopping guide is used as a guideline to assist shoppers when selecting foods. The meal cards provide some sample recipes or cooking tips for shoppers to learn how to cook nutritious meals. Shoppers may use the ingredients from the cards to generate a healthy shopping list.
