(The Eurographics Association, 2025) Pitikaki, Vasileia Eirini; Troulis, Emmanouil; Leonidis, Asterios; Korozi, Maria; Stephanidis, Constantine; Campana, Stefano; Ferdani, Daniele; Graf, Holger; Guidi, Gabriele; Hegarty, Zackary; Pescarin, Sofia; Remondino, Fabio
While immersive technologies are becoming more prevalent in museums and exhibition spaces, significant opportunities remain to enhance visitor engagement through more interactive and meaningful experiences. At the same time, physical space limitations often restrict the number of artifacts on display, preventing institutions from showcasing the full richness of their collections to the public. To address these challenges, a platform named FRAMES was designed and developed. Initially implemented in a CAVE-like environment, FRAMES facilitates multi-user interactivity and social engagement, promotes cultural heritage dissemination, and supports the digital transformation of museum experiences. Key features include personalized interactions, accessibility, and Augmented Reality enhancements. To demonstrate its capabilities, VanoArt, an instance of FRAMES for art galleries, was created. A cognitive evaluation with UX experts confirmed the system's effectiveness in enhancing immersion, interactivity, and user engagement. These findings highlight FRAMES' potential to reshape digital exhibition practices and enrich cultural experiences.

Virtual Reality (VR) revolutionised the way the users can perceive virtual or distant spaces and interact with them. The users wearing VR headsets have the impression as if they would look around at the real place of the sights. The technology is widely used in entertainment and training. Our goal was to examine how the VR technology can be applied to present sacral spaces. We assembled the virtual reality model of a Bulgarian Orthodox church in a cost-effective manner from high-resolution spherical panorama pictures. A complex VR exploration platform was created by integrating our VR presentation tool with the digital repository of Bulgarian icons and iconographic objects. Due to the integration, additional information can be displayed on specific frescoes of the church in the VR space. We offer a full-fledged virtual exploration of sacred spaces where the experience of moving around the virtual space and exploring the details of the church can be combined with transferring lexical knowledge about the church and its selected objects. The first versions of our virtual walks were available on the Web only. Due to the multiplatform development methodology applied, virtual walks can be demonstrated on VR as well.
Integrating Artificial Intelligence in the Design of Interactive Experiences. An Overview for Digital Cultural Heritage Practitioners
(The Eurographics Association, 2025) Veggi, Manuele; Campana, Stefano; Ferdani, Daniele; Graf, Holger; Guidi, Gabriele; Hegarty, Zackary; Pescarin, Sofia; Remondino, Fabio
This paper explores the integration of Artificial Intelligence (AI) in the design of interactive experiences for Cultural Heritage (CH). Previous studies indeed either miss to represent the specificity of the CH or mention possible tools without making a clear reference to a structured Interaction Design (IxD) workflow. The study also attempts to overcome one of the major limitations of traditional literature review, which may fail to capture proprietary tools whose release is rarely accompanied by academic publications. Besides the analysis of previous research, the study proposes a possible workflow for IxD in CH, subdivided into phases and tasks: for each of them, this paper proposes possible AI-based tools that can support the activity of designers, curators, and CH professionals. The review concludes with a final section outlining future paths for research and development in this domain.
OpenLIME: An open and flexible web framework for creating and exploring complex multi-layered relightable image models
(The Eurographics Association, 2025) Ponchio, Federico; Bettio, Fabio; Marton, Fabio; Pintus, Ruggero; Righetto, Leonardo; Giachetti, Andrea; Gobbetti, Enrico; Campana, Stefano; Ferdani, Daniele; Graf, Holger; Guidi, Gabriele; Hegarty, Zackary; Pescarin, Sofia; Remondino, Fabio
We introduce OpenLIME (Open Layered IMage Explorer), an open, scalable, and flexible framework for creating web-based interactive tools to annotate and inspect large multi-layered and multi-channel standard and relightable image models. Adaptive image management and display use a data-flow approach, where images from sources of any size are efficiently streamed into screen-sized buffers that can be processed and combined using customizable WebGL shaders. The framework natively supports multispectral images, Bidirectional Reflectance Distribution Function (BRDF), and Reflectance Transformation Imaging (RTI) datasets and can be extended to accommodate other multi-channel raster datasets, such as neural representations. Multi-layer and multi-faceted visualizations are achieved through opacity adjustments, blending modes, and interactive lenses. The released library provides a set of pre-configured layers, facilitating the rapid deployment of web-based datasets and kiosk applications. Its responsive user interface is compatible with desktop, mobile, and general multitouch environments, while its modular architecture allows for extensive customization, making it adaptable to diverse annotation and visualization needs. The paper illustrates the framework's design and discusses specific use cases, including the inspection of RTI models, the integration of novel relightable image formats, archaeological data documentation and annotation, and standalone museum application creation and deployment. The main components of the framework are released as open source.
Prague Astronomical Clock - Virtual Presentation
(The Eurographics Association, 2025) Ubik, Sven; Linhart, Oldrich; Kubišta, Jirí; Skála, Petr; Knespl, David; Mašek, Jirí; Rocek, Jakub; Campana, Stefano; Ferdani, Daniele; Graf, Holger; Guidi, Gabriele; Hegarty, Zackary; Pescarin, Sofia; Remondino, Fabio
The Prague astronomical clock is a medieval astronomical clock in the Old Town Square in Prague. It is the oldest original working astronomical clock and the most visited astronomical clock in the world. However, many visitors have limited information about its history and the function of the Astrolabe. The clockwork itself is not commonly accessible. The aim of the project described here was to present a digital replica of all parts of the Prague astronomical clock and to make information about the clock available to researchers, students and the general public. In this paper, we show how the model was presented and we evaluate user feedback on the presentation.
Remaking Lost Communities in Virtual Cultural Landscapes
(The Eurographics Association, 2025) Zhang, Junyu; Sturdee, Miriam; Miller, Alan; Oliver, Iain; Aitken, Jacquie; Campana, Stefano; Ferdani, Daniele; Graf, Holger; Guidi, Gabriele; Hegarty, Zackary; Pescarin, Sofia; Remondino, Fabio
Characters in immersive, Virtual Reality environments have the potential to enrich the user experience, improving engagement with heritage, and in doing so, benefiting heritage organisations and their communities. By creating authentic digital scenes based upon archaeological and historical data, we enable these communities and their visitors to better understand the past. Often, historical reconstructions can appear empty, focused on the landscape and architecture, yet omitting animals, people and associated intangible heritage. We demonstrate the potential of enriching these reconstructions with the details of lives past.
Stereo Spectacular: Reviving the Universal Exposition of 1867 in Virtual Reality through Historical Stereoscopic Photographs
(The Eurographics Association, 2025) Storz, Dhruva Gowda; Mannane, Samy; Ramogida, Tonia; Cardot, Toussain; Kenderdine, Sarah; Campana, Stefano; Ferdani, Daniele; Graf, Holger; Guidi, Gabriele; Hegarty, Zackary; Pescarin, Sofia; Remondino, Fabio
Stereo Spectacular unites 19th-century stereoscopic immersive media with contemporary virtual reality technologies, reconstructing the Exposition Universelle of Paris 1867 (UE1867) through archival stereoscopic photographs within an immersive museum experience. As a landmark historical event, the expo marked a turning point in visual culture. Part of the Expo's spectacular appeal involved the use of contemporary technologies in the service of museography and art. One such technology was stereography, which was used to extensively document the event through 1000+ stereoscopic photographs. Stereo Spectacular presents a navigable art-tectonic virtual reconstruction of the UE1867: hundreds of digitized, restored, geolocated, augmented, and sonified stereo pairs are configured into a navigable, map-based visual space that museum audiences can freely explore. Stereo Spectacular is built for a state-of-the-art multi-user 360° stereoscopic virtual reality system, but is scalable to any and all virtual reality and stereoscopic visualization hardware. The project presents a novel curatorial framework for reconstituting and reconfiguring stereo archives into compelling reconstructions of place and time. It demonstrates how image archives can become navigable VR places, and how multisensory augmentations can be used to shed new light on visions of the past. Importantly, the project transforms the individually viewed stereo pair into a socially experienced visual space, reinventing the historical stereo viewing experience, and - in the case of the UE1867 - reinterpreting the experience of visiting the fair through contemporary immersive visualization.
Swiss Echoes: An immersive and embodied exploration of a national broadcasting archive
(The Eurographics Association, 2025) Alliata, Giacomo; Serafin, Loïc; Rattinger, André; Kenderdine, Sarah; Campana, Stefano; Ferdani, Daniele; Graf, Holger; Guidi, Gabriele; Hegarty, Zackary; Pescarin, Sofia; Remondino, Fabio
This paper answers the need for new modes of access for large audiovisual collections and builds on top of the computational and immersive turn of the cultural sector. The immersive installation Swiss Echoes fosters an embodied and spatialised paradigm in which visitors fly over a topographical 3D map of the Swiss landscape to discover how the voices captured in the national broadcasting archive of the Radio Télévision Suisse talk about local places. Through a reflection on the design rationale supported by key insights from a user evaluation conducted at our laboratory, three main themes are elucidated. First, the computational augmentation of the archive foregrounds access to a collection of locations rather than videos. Second, the use of an immersive environment and a performative controller fosters a profoundly embodied mode of spatial exploration. Third, sharing the immersive experience between multiple visitors creates a collective form of engagement, where the main visitor interacting becomes a performer and director for the others.
