This document discusses the development of augmented reality applications to overlay historical photos from the PhillyHistory.org collection onto current street views. It received a grant to develop a prototype app allowing users to view additional contextual information about locations by pointing their phone's camera at them. Key challenges include accuracy, interface design, and performance. The goal is to engage the public in history by bringing the past to life in the present environment.
