Mobile augmented reality for interpretation of archaeological sites

Heritage interpretation plays a key role in understanding, imagining, and appreciating tangible cultural heritage, including historic sites. Interpretation becomes critical for visitors to historic sites that are partially or fully buried or in ruins, which is most often the case for archaeological sites. However, it remains a challenge for developers of AR systems and content to navigate the plethora of technologies and requirements in this evolving area. In response, we present the design of Arbela Layers Uncovered (ALU), a mobile Augmented Reality (AR) system for the ancient site of Arbela, Iraq. The site consists of an accumulation of buried layers left by successive civilizations inhabiting the area. In addition to describing the objectives of ALU, we discuss the development of a proof-of-concept and the design decisions involved. ALU features media for guiding visitors and interpreting and presenting the complex and multifaceted history of the site.
