Exploring Cultural Heritage Using Augmented Reality Through Google’s Project Tango and ARCore

This research is focused on the importance of using modern technologies in preserving and exploring Cultural Heritage (CH). Specifically, Augmented Reality (AR) has the potential to enhance the user experience related to cultural heritage. We briefly present the main technological approaches in CH and a state of the art in mobile augmented reality. The latest Software Development Kit (SDK) for building AR applications are reviewed and compared. The 3D object that participants could place in the real environment was obtained using photogrammetry, a popular and relatively easy to use digitization technique. The virtual object represents a fortified church and is part of a group of UNESCO monuments from the historical and ethnographical region called “Țara Bârsei”, located in Brasov, Romania. We also provided some guidelines to ensure an accurate 3D reconstruction of any object. We assess users’ perception regarding two mobile AR applications, one based on Project Tango while the other was developed using ARCore. Results confirm that AR improves user experience and increases the enjoyment of learning about cultural heritage.
