This work describes the design and development process of an interactive ordering system for rural corner stores, extending the limited assortment of a small store with virtual items on touch-sensitive displays embedded into shelves. The interface blends tangible interaction of both real products in a shelf and virtual products iconically represented on nearby screens. The tangible interaction component is complemented by a natural language interface, supporting comparison and inspection of multiple products of the real and virtual world.
