HistoryLens is a tool designed to enhance the value of historical photos through Augmented Reality (AR) solutions and more engaging ways to visualise and interact with heritage content. The tool is, in particular, a template project created to support the creation of AR applications in diverse urban contexts to visualise historical photos superimposed on real-world scenarios. The applications will enable the exploration of augmented digital content (photos) placed in the original shooting position through smartphones or tablets.
