Archaeologists at the University of Hong Kong are pioneering the use of mixed and augmented reality (MR/AR) technologies to enhance the excavation of ancient sites.

These technologies, including MR headsets like the Microsoft HoloLens 2, allow researchers to interactively apply digital 3D scientific data at excavation sites.

The use of these technologies aims to mitigate the perception of archaeology as a 'destructive science' by reducing unnecessary excavation and artifact removal.

AR smart glasses are also utilized for hands-free data collection, allowing archaeologists to capture photographs and take notes using voice recognition while excavating.

This project exemplifies a collaboration between the humanities and engineering, supported by HKU's Faculty of Engineering, which provides essential technology and expertise.

Professor Cobb presented these innovations at New York University's Institute for the Study of the Ancient World on November 13, 2024.

Additionally, MR headsets facilitate the comparison of 3D scanned pottery fragments with physical artifacts, improving the analysis of museum collections.

Ph.D. candidate Mr. Hayk Azizbekyan, who leads the research, describes the integration of MR and AR as a groundbreaking innovation that transforms archaeological practices.

Professor Peter J. Cobb noted that MR devices enable archaeologists to visualize removed structures in their original locations, significantly aiding decision-making during digs.

The team's findings have been documented in the Journal of Computer Applications in Archaeology, highlighting the novelty of their approach within the academic community.

Looking ahead, the team envisions future applications of AI to assist in matching pottery sherds based on shapes, further enhancing archaeological studies.

The HKU team has successfully tested these technologies during a field project in Armenia, focusing on the excavation of ancient stone walls and pottery.
