PhySig: Incorporating Physical Products with Digital Signage in Shopping Environments
In this paper, we propose the concepts, design guidelines, and implementation details of PhySig, a novel interactive in-store shopping experience that annotates information about products, which are physically located in the store, by a projector and enables shared content between the products and mobile devices. Multiple users access the system from their own mobile devices to move a cursor projected on the wall or floor of the store to select an item and obtain additional information associated with the item in the projected space. They can also download the information to their mobile devices or upload their related content, including comments, reviews, or photos, of the item. In short, PhySig is an example of how to extend and combine digital signage with the surrounding physical environment.
