Abstract
The aim of this paper is to present the use of 3D models and augmented reality (AR) to study and communicate architectural and urban values and, therefore, favor the development of dedicated forms of “smart heritage”. The study rises from a reflection on the concept of “heritage”, as defined in the international documents, intended as an evolving idea that puts together tangible and intangible aspects. Moreover, digital technologies favor “phygital” applications where the digital dimension support the traditional ones. In this way, AR allows the superimposition of multimedia information to heritage, respecting the historical matter of the artefacts, and supporting a “smart heritage” application. In particular, mobile AR, with real-time and ubiquitous visualizations, offers the opportunity to show past urban and architectural configurations to investigate and describe the transformations that have led to the current configuration, and consequently highlighting the present historical and architectural values of the buildings. Two case studies are presented: the square of St. Basilio Monastery, with its historical transformations, and the Basilica of Collemaggio, a pivotal building in the rites of “Perdonanza Celestiniana”.
Highlights
The aim of this paper is to present the use of 3D models and augmented reality (AR) to study and communicate architectural and urban values and, favor the development of dedicated forms of “smart heritage”
The digital technologies have become increasingly important, first of all because they are an integral part of everyday life, and second, because they offer new ways of viewing information: in particular, the different forms of mixed reality [5] allow the superimposition of information of different nature on architectural heritage without interfering with its materiality, i.e., by acting only in the dimension of the visual [6]
This application to cultural heritage can favor the development of new forms of smart heritage
Summary
The paper presents the activities of the “Innovating City Planning through Information and Communication Technologies” (INCIPICT) + 5G interdisciplinary project of the University of L’Aquila (http://incipict.univaq.it/, accessed on 25 August 2021) related to cultural heritage valorization [14]. The activities aim at documenting the profound processes of change in a historical center hit hard by an earthquake, and to encourage the understanding of the values of the places and the reconstruction ofdemonstrate their meaning onsite storytelling history: the ICT to the contents thethrough validity the of the methodology forof thetheir enhancement of arare designed to allow, freely infuture, the historical center, to superimpose chitectural heritage It ismoving planned, in the to enrich the visualizations withmultimedia multimeinformation of different past configurations on the backgrounds, images framedtoby smart dia contents,and and3D to reconstructions include people of ages and cultural repeat devices, without.
