Geospatial Archaeological Information Visualisation and Mixed Reality: Enhancing Visitors’ Meaningful Engagement with Archaeological Sites

Abstract

This paper introduces an innovative application of Mixed Reality (MR) technology in the form of an open-source platform, namely Mergin’ Mode that aims to visualise archaeological information for both expert and non-expert audiences. This platform is presented in the context of a pilot study conducted in the process of finalising the system’s characteristics and interface, which involved the visualisation of an ottoman bath in Apollonia, Central Macedonia, Greece. Emphasis is also put on the workflow needed for presenting archaeological sites through Mixed Reality (MR) technologies and related issues concerning how such MR applications can provide visitors with a more meaningful and active engagement with monuments. As a case study of the new ways of communicating archaeological information in an accurate and engaging manner, we present Mergin’ Mode. This includes two platforms, the authoring tool for composing virtual worlds and a client panel for visualisation purposes, which are showcased through the way they represent the ottoman bath in Apollonia in its original state through MR. Moreover, juxtaposition, through overlaying the monument’s original state unto its current state, allows for an enhanced understanding of the buildings’ form and past function. In the case of Mergin’ Mode, Mixed Reality, Augmented Reality (AR) and Virtual Reality (VR) are supported, employed and offered as visualisation options to users, such as archaeologists and cultural tourists. These user-friendly interactive features provide a holistic experience, adding value to heritage site visits. Mergin’ Mode combines photogrammetry, GIS and cutting-edge MR/VR visualisation technologies to render archaeological sites in a scientifically sound and profoundly engaging manner.
