“…Using the 2D ground plan of the residential area as a marker ( Figure A1) allows the real perception of the remains and relief in 3D via a smartphone or a tablet. This form of presentation can be applied directly at the site using an information board with any kind of marker, e.g., [60]; after downloading the designed application, th visitor will immediately gain an overall vision of all remains and topographic setting of the site. In the case of Hound Tor, not only can the preserved relics of buildings, but also its wider archaeological landscape with different remains, be perceived.…”

Airborne laser scanning (ALS) data is increasingly distributed freely for ever larger territories, albeit usually in only low resolution. This data source is extensively used in archaeology; however, various remains of past human activities are not recorded in sufficient detail, or are missing completely. The main purpose of this paper is to present a cost-effective approach providing reliable and accurate 3D documentation of the deserted medieval settlement of Hound Tor, a complex site consisting of preserved stone building walls and field system remains. The proposed procedure integrates ALS data with structure from motion (SfM) photogrammetry into a single data source (point cloud). Taking advantage of the benefits of both techniques (reclassified ALS data documents the hinterland, while SfM records the residential area in high detail), an enhanced 3D model has been created surpassing the available ALS data and reflecting the actual state of preserved features. The final outputs will help with the management of the site, its presentation to the general public, and also to enrich understanding of it. As both data sources are currently easily accessible and the proposed procedure has only limited budget requirements, it can be easily adopted and applied extensively (e.g., for virtual preservation of threatened complex sites and areas).

“…With respect to the use of AR in heritage contexts, useful studies have hailed from Spain [29], Italy [17,30], Greece [31,32], the Czech Republic [33], Taiwan [26,34], Korea [35,36], and Malaysia [37]. It should not be forgotten that many of these initiatives resulted from the first AR and VR projects funded by the European Union at the beginning of the 2000s, such as Lifeplus [38], Archeoguide [39], Itacitus [17], and Ancient Pompeii [37,38].…”

“…Technology has progressively changed and advanced so as to enable access to AR, which can be activated in some apps by scanning QR codes or other user markers [7,22,33] (see Figure 1), while in others, this is done through activating GPS [22,31]. Other devices such as Google Glasses [11] and other types of goggles have also been used for this purpose-though these run into greater limitations since they constitute yet another costly gadget that users must obtain.…”

Augmented Reality in Heritage Apps:Current Trends in Europe

Although augmented reality (AR) has come to play an increasingly important role in a wide range of areas, its use remains rather limited in the realm of heritage education. This paper sets out to analyze which heritage-related apps can be found in Europe that partly or wholly use AR as a tool to help users learn about different types of heritage. Our study only identified a limited number of such apps and we used this sample both to paint a portrait of the current state of the question and also to highlight certain observable trends. The results showed that most such apps used AR to reconstruct spaces and buildings, and to a lesser extent, objects. Many of these apps used an academic mode of communication to provide a temporal perspective of monumental and (mainly) historical heritage. The paper also outlines future lines of research dedicated to finding more apps that could be used to increase the current sample size. This would allow for a more comprehensive assessment of such apps from an educational point of view. Several case studies are proffered in order to highlight the keys to successful use of AR in heritage apps.

“…Currently, markerless mixed reality explorative/reconstructive applications account for less than 1.5% of the total virtuality continuum software programmes used in cultural heritage and archaeology [3]. The vast majority of this 1.5% consists of cultural heritage projects, and only a small portion are archaeological applications [12,13]. Furthermore, from this fraction, a limited number of projects deal directly with the field of excavation.…”

Reconstructive Archaeology: In Situ Visualisation of Previously Excavated Finds and Features through an Ongoing Mixed Reality Process

Archaeological excavation is a demolishing process. Rather few elements outlast extractive operations. Therefore, it is hard to visualise the precise location of unearthed finds at a previously excavated research area. Here, we present a mixed reality environment that displays in situ 3D models of features that were formerly extracted and recorded with 3D coordinates during unearthing operations. We created a tablet application that allows the user to view the position, orientation and dimensions of every recorded find while freely moving around the archaeological site with the device. To anchor the model, we used physical landmarks left at the excavation. A series of customised forms were created to show (onscreen) the different types of features by superimposing them over the terrain as perceived by the tablet camera. The application permits zooming-in, zooming-out, querying for specific artefacts and reading metadata associated with the archaeological elements. When at the office, our environment enables accurate visualisations of the 3D geometry concerning previously unearthed features and their spatial relationships. The application operates using the Swift programming language, Python scripts and ARKit technology. We present here an example of its use at Les Cottés, France, a palaeolithic site where thousands of artefacts are excavated out of six superimposed layers with a complex conformation.
