Users are invited to be physically present at specific locations to experience AR artworks in situ. When users select the Coordinates feature, based on their location, they will be directed toward artworks – translated into AR-- created by artists that activate the historically, politically or culturally significant sites they have chosen. “Coordinates” aims to inspire thoughtful dialogue and expand our understanding of public art.
