Columbus is a mobile application for exploring the physical world with geotagged photos. The access to the geotagged photos are restricted so that you must physically move to the place where photos are tagged in order to find them. Columbus explores how space and place and localized digital content can be explored together. Our user studies have for example showed differences in usage and user behavior depending on the setting, for example whether people are exploring areas they know or those they do not. Through exploring how people appropriate apps like Columbus, we develop design guidelines for apps that enable localized content consumption.
