abstract = {Exploration activities, such as tourism, cultural heritage, and science, enhance knowledge and understanding. The rise of 360-degree videos allows users to explore cultural landmarks and destinations remotely. While multi-user VR environments encourage collaboration, single-user experiences often lack social interaction. Generative AI, particularly Large Language Models (LLMs), offer a way to improve single-user VR exploration through AI-driven virtual assistants, acting as tour guides or storytellers. However, it’s uncertain whether these assistants require a visual presence, and if so, what form it should take. To investigate this, we developed an AI-based assistant in three different forms: a voice-only avatar, a 3D human-sized avatar, and a mini-hologram avatar, and conducted a user study to evaluate their impact on user experience. The study, which involved 12 participants, found that the visual embodiments significantly reduce feelings of being alone, with distinct user preferences between the Human-sized avatar and the Mini hologram. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.},

abstract = {The quick development of generative artificial intelligence (GenAI) techniques is a promising step toward automated processes in the field of cultural heritage (CH). The recent rise of powerful Large Language Models (LLMs) like ChatGPT has made them a commonly utilized tool for a wide range of tasks across various fields. In this paper, we introduce LLMs as a guide in the three-dimensional (3D) panoramic virtual tour of the Civic Art Gallery of Ascoli to enable visitors to express their interest and show them the requested content. The input to our algorithm is a user request in natural language. The processing tasks are performed with the OpenAI’s Generative Pre-trained Transformer (GPT) 4o model. Requests are handled through the OpenAI’s API. We demonstrate all the functionalities within a developed local web-based application. This novel approach is capable of solving the problem of generic guided tours in the museum and offers a solution for the more automatized and personalized ones. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.},

abstract = {The emergence of Virtual Reality (VR) and meta-verse have opened doors to new research opportunities and frontiers in User Experience (UX). Within the cultural heritage domain, one of the key concepts is that of the Virtual Museums (VMs), whose definition has been extended through time by many research works and applications. However, most of the studies performed so far focused on only one application, and studied its UX without taking into account the experience with other VR experiences possibly available in the VM. The purpose of this work is to give a contribution for an optimal design to create a unified UX across multiple VR experiences. More specifically, the research included the development of two applications, respectively a VM in a metaverse platform and a virtual learning workshop as an individual application. With this premise, the study will also consider two fundamental elements for an effective UX design: a Virtual Environment (VE) and an Intelligent Virtual Avatar (IVA). In particular, the latest was developed following current trends about generative AI, integrating an IVA powered by a Large Language Model (LLM). © 2024 IEEE.},

abstract = {Improving accessibility to Cultural Heritage (CH) is an increasingly urgent challenge today. It is not only a matter of physical inaccessibility but also temporal, considering that part of CH now lost. Fortunately, the most modern technological tools are helping to break down both space and time barriers. In facts, recent advances in representation, 3D modelling and survey methodologies opened new scenarios for valorization and conservation of CH. In particular, the improvement of quality in resolution and sensor sensitivity of cameras allowed to achieve the right level of 3D reconstruction through digital photogrammetry procedures. In the same field, terrestrial laser scanners (TLS) allowed acquiring dense point clouds of complex environments with a millimetric level of accuracy. At the same time, the application of Augmented Reality (AR) and Virtual Reality (VR) technologies is an excellent solution for improving the accessibility to monuments, museums and archaeological sites. It is possible to share new levels of information about CH, in space and time, for touristic, managerial and scientific aims. This work is focused on the virtualization of CH, considering the study case of the fountain of Wignacourt, today present in St. Philip Garden in Floriana and initially located in Valletta (Malta). The application presented allows the virtual fruition of the monument placed in its original location, St. George Square. A simplified plant of the square will enable tourists to make a temporal journey in the past with their mobile device. The work is part of the Interreg Italia-Malta European project named I-Access, dedicated to the improvement of CH accessibility. It focuses the attention to the experimentation of new specific procedures in Geomatics necessary to solve big data issues of complex environment visualization. © Authors 2020.},

abstract = {The extension of accessibility of CH to disabled people is a current topic of great importance. Today, there exist a lot of ongoing projects aimed at the extension of accessibility using the most recent and low cost technologies to improve accessibility to CH. One of the technologies, today available that can help to improve accessibility to CH, is certainly rapid prototyping. The main goal of the research here illustrated is the application of rapid prototyping for the extension of accessibility of Cultural Heritage (CH) to blind and visually impaired people. This document reports an experiment that compared the effectiveness of different 3D models for the introduction of blind and visually impaired people to the tactile use of models of monuments. In addition, this study focuses on defining standards and guidelines regarding features of 3D models, e.g. print resolution, in order to obtain greater legibility of models at different scales by the blind or visually impaired people. This paper shows a part of a wider Interreg EU research project, named I-ACCESS, aimed to study accessibility problems and solutions for CH. The experiments conducted with the sample of disabled people, allowed to obtain results on the most suitable printing parameters to be used. © 2019 International Society for Photogrammetry and Remote Sensing.

abstract = {The case study, faced in this paper, arises in the context of Interreg Italia-Malta European project named I-Access, dedicated to the improvement of accessibility to Cultural Heritage (CH). Accessibility considered not only as the demolition of physical architectural barriers, but also as the possibility of fruition of CH through technological tools that can increase its perception and knowledge. Last achievements in photogrammetry and terrestrial laser scanner (TLS) technology offered new methods of data acquisition in the field of CH, giving the possibility of monitoring and processing big data, in the form of point clouds. Ever in this field, reverse engineering techniques and computer graphics are even more used for involving visitors to discover CH, with navigation into 3D reconstructions, empowering the real visualization adding further 3D information through the Augmented Reality (AR). At the same time, recent advances on rapid prototyping technologies grant the automated 3D printing of scaled 3D model reconstructions of real CH elements allowing the tactile fruition of visitors that suffer from visual defects and the connection with 3D AR visualizations. The presented work shows how these technologies could revive an historical square, the Piazza Garraffo in Palermo (Italy), with the virtual insertion of its baroque fountain, originally placed there. The final products of this work are an indoor and an outdoor AR mobile application, that allow the visualization of the historical original asset of the square. This study case shows how the mixing of AR and the rapid prototyping technologies could be useful for the improvement of the fruition of CH. This work could be considered a multidisciplinary experimentation, where different technologies, today still in development, contribute to the same goal aimed at improving the accessibility of the monument for enhancing the fruition of CH. © Authors 2019.

abstract = {Recently, the diffusion of knowledge on Cultural Heritage (CH) has become an element of primary importance for its valorization. At the same time, the diffusion of surveys based on U AV Unmanned Aerial Vehicles (UAV) technologies and new methods of photogrammetric reconstruction have opened new possibilities for 3D CH representation. Furthermore the recent development of faster and more stable internet connections leads people to increase the use of mobile devices. In the light of all this, the importance of the development of Virtual Reality (VR) environments applied to CH is strategic for the diffusion of knowledge in a smart solution. In particular, the present work shows how, starting from a basic survey and the further photogrammetric reconstruction of a cultural good, is possible to built a 3D CH interactive information system useful for desktop and mobile devices. For this experimentation the Arab-Norman church of the Trinity of Delia (in Castelvetrano-Sicily-Italy) has been adopted as case study. The survey operations have been carried out considering different rapid methods of acquisition (UAV camera, SLR camera and smartphone camera). The web platform to publish the 3D information has been built using HTML5 markup language and WebGL JavaScript libraries (Three.js libraries). This work presents the construction of a 3D navigation system for a web-browsing of a virtual CH environment, with the integration of first person controls and 3D popup links. This contribution adds a further step to enrich the possibilities of open-source technologies applied to the world of CH valorization on web. © Authors 2018. CC BY 4.0 License.},

abstract = {During the last years, many solutions have been proposed for 3D Virtual Heritage representations. Recently, also new technologies for online gaming evolved, based on javascript libraries (WebGL), used to create and publish virtual interactive environments. They are based on recent Web browser's functionalities, surpassing some limitations of VRML technologies. On the side of geospatial information, technology has evolved from desktop GIS to 2D WebGIS and globe applications. The use of globe applications is, today, very diffused due to its immediate and at the same time impressive representation of the earth surface and territories. These technologies have been, also, applied to Virtual Heritage 3D reconstructions, to improve the fruition of Cultural Heritage (CH), with the achievement of interesting results. The topic of this paper is the experimentation on the fusion between globe based and gaming technologies (in our case WebGL) that allow achieving a more user-centric and powerful solution useful for publishing 3D geospatial information of CH on Web. This choice allows obtaining GIS oriented 3D models, typical of globe applications, and, at the same time, a more immersive exploration of CH and its surrounding environment. In particular, it also gives complementary text and multimedia information on the history, architectural features of each cultural good, based on querying of semantic information. The test field of the research is the construction of the 3D GIS virtual globe model of the Manfredonic Castle of Mussomeli (Sicily-Italy), developed for PON-NEPTIS EU Project, to compare open-source technologies and commercial proprietary applications. © Authors 2018.

abstract = {The last achievements of technologies in geomatics especially in survey and restitution of 3D models (UAV/drones andlaser scanner technologies) generated new procedures and higher standards of quality in representation of archaeological sites. Together with Geomatics, the recent development of Information and Communication Technologies (ICT) strongly contribute to document and the Cultural Heritage (CH). The representation and documentation of CH using these new technologies has became necessary in orderto satisfy different needs: -for restorers in order to acquire a deep knowledge of the cultural good and to define possible strategiesof restoration; -for the conservation of information, allowing to preserve the 3D geometry of the monumental complex with the integration of descriptions about architectural elements; -for touristic aims, giving the opportunity of sharing CH information on web, allowing users to visit and explore, in a virtual way,monumental complexes, acquiring information details about architectural elementsorthe history of monumental complex. Looking through these new scenarios, the development of a 3D Geographic Information System (GIS) applied to a cultural good could be,today,an added value of fundamental importance for full description and data managementof monumental complexes. In this work,the main features necessary for the correct construction of a 3D GIS of a monumental complex will be analyzed, with a particular focus on the possibilities for creating a standardized procedure to follow.},

abstract = {In the last few years, the need to share on the Web the knowledge of Cultural Heritage (CH) through navigable 3D models has increased. This need requires the availability of Web-based virtual reality systems and 3D WEBGIS. In order to make the information available to all stakeholders, these instruments should be powerful and at the same time very user-friendly. However, research and experiments carried out so far show that a standardized methodology doesn't exist. All this is due both to complexity and dimensions of geometric models to be published, on the one hand, and to excessive costs of hardware and software tools, on the other. In light of this background, the paper describes a methodological approach for creating 3D models of CH, freely exportable on the Web, based on HTML5 and free and open source software. HTML5, supporting the WebGL standard, allows the exploration of 3D spatial models using most used Web browsers like Chrome, Firefox, Safari, Internet Explorer. The methodological workflow here described has been tested for the construction of a multimedia geo-spatial platform developed for three-dimensional exploration and documentation of the ancient theatres of Segesta and of Carthage, and the surrounding landscapes. The experimental application has allowed us to explore the potential and limitations of sharing on the Web of 3D CH models based on WebGL standard. Sharing capabilities could be extended defining suitable geospatial Web-services based on capabilities of HTML5 and WebGL technology.},
