Aura is an augmented reality concept for historical sites, galleries and museums. Once a user is around a tagged object, the app recognizes the object and projects a cloud of informational “grains” floating around the object. When a user clicks on this cloud, a conversational interface opens, providing access to the information about an object. This project was selected as finalist in the Playable Museum Awards 2018 of Fondazione Cassa di Risparmio di Firenze and Museo Marino Marini in Florence, Italy. http://www.penccil.com/movie/aurazhiqi.mp4
