1 Simplify their view of the store.
A simplified but accurate representation of the store eliminates unnecessary elements much like a subway map does for a city. Design the map of the store so that it divides the complex space into smaller, more easily identifiable and navigable areas. Focus on districts (produce), landmarks (citrus fruit table), and routes (take me to the oranges) as well as the holistic view of the store. These varying levels of focus allows shoppers to identify familiar landmarks and regain their orientation within the environment.
2 Focus on items of explicit interest to the shopper.
Shopping lists and other explicit declarations of intent allow the application to further simplify the view of the store by focusing distinctly on the items, routes and landmarks relevant to the products shoppers have chosen. Ideally, these lists are the primary refinement that defines how we virtually represent the physical environment. Therefore it’s important to allow shoppers to create or edit lists whenever and wherever is convenient. This includes planning at home, while shopping, etc. More on this in “Be fun, smart, attentive, and efficient”.
The complexity of the store environment is relative to the abilities of the individual shopper as well as their familiarity with the environment. Novice users and individuals with physical or cognitive deficiencies greatly benefit from simplified representations of complex environments and situations like those associated with shopping.
