Item Interactive Showcase and Museum Guide System using Bluetooth Low Energy Beacons(IEEE, 2015) Pantile, Davide; Ventrella, Matteo; Mazzeo, Antonio; Sofia Pescarin and Pedro Cano and Alfredo GrandeThe Interactive Showcase and the Museum Guide System are two technologies designed and produced by ETT using Bluetooth Low Energy Beacons. These innovoative porduts allow technology to be integrated into the heritage sector in a more effective and engaging way.Item X-Top - An Interactive Exhibition for Building Experience with Mini-Components of Stone Pagoda(IEEE, 2015) Kang, Kyung-Kyu; Lee, Jihyung; Park, Chang Joon; Kim, Jae Woo; Lee, Man Hee; Gabriele Guidi and Roberto Scopigno and Pere BrunetStone pagodas are mysterious heritages about how to be built up and shaped stone components. X-Top is an interactive exhibition system to explore answering about the building method of a famous Korean stone pagoda. Previous digital heritage applications are difficult to give users tangible experiences. We propose an exhibition system(X-Top) to allow visitors to build up a pagoda with its miniature components. We exhibited the X-Top system on various exhibitions and can get positive feedback from visitors. Our project is still working on developing with many types of digital heritage applications.Item VirtualTour: A System for Exploring Cultural Heritage Sites in an Immersive Way(IEEE, 2015) Malomo, Luigi; Banterle, Francesco; Pingi, Paolo; Gabellone, Francesco; Scopigno, Roberto; Gabriele Guidi and Roberto Scopigno and Pere BrunetIn this paper, we propose VirtualTour. This is a virtual reality app for Apple iOS 8 (tablets, smartphones) supporting the easy and natural exploration of Cultural Heritage sites captured with 3D scanning technologies or modeled by artists. VirtualTour proposes a novel approach for exploring virtual sites by exploiting modern mobile devices (tablets or phones) and their embedded sensors. The navigation is constrained to follow a pre-defined path in the virtual space; the user can progress on the path either by manipulating a simple slider or directly walking in real-world (the device sensors detect user's steps and progress accordingly in the virtual visit). The view is rotated according to mobile device's rotation (again, using the device sensors). The main focus of this app is to provide a mobile access to hidden or inaccessible sites (e.g. caves, temples, buildings, etc), using 3D representation and breaking the usability barrier that often hinders the navigation in complex models on top of mobile devices.Item Unraveling the Classic Proportions Through the Anthropometric Analysis of the Architectural Heritage The Case of the Pantheon(IEEE, 2015) Roldan-Medina, Francisco Javier; Gabriele Guidi and Roberto Scopigno and Juan BarcelóPrevious results of this research allow to raise the Hypothesis that a simple metric law is sufficient to justify the different dimensions of the various parts composing ancient architectural constructions, from its general layout to every single detail. This Hypothesis is based on the observation that any modulation in historic buildings match with the sides and diagonals of human-sized square pattern, and its duodecimal divisions. However, it´s not possible to match exclusively to the side-square scale, because the Side-Diagonal Dual Scale is necessary, and is sufficient. The analysis of scientific surveys with digital precision led to find the serendipity beyond the current state of the art demonstrating the compliance with this law in architectural works of very different historical periods. This research deals with the study of the Pantheon through the survey of the Bern Digital Pantheon Project. It is highlighted that from the obtained results, in addition to the compliance of the Principle of Proportionality proposed, the Pantheon presents similar modular patterns to those detected in other examples. Knowledge of this common System of Proportions used in the past could represent a scientific breakthrough or new paradigm in the study and preservation of architectural heritage.Item Application of georeferenced Archaeological Information Systems for Archaeological Digital Heritage - The Auxiliary Fortress of Carnuntum (Lower Austria)(IEEE, 2015) Wallner, Mario; Juan, Torrejón Valdelomar; Neubauer, Wolfgang; Kucera, Matthias; Brandtner, Joachim; Sandici, Vlad; Gabriele Guidi and Roberto Scopigno and Fabio RemondinoNon-destructive prospection methods provide a powerful toolbox to explore Archaeological Heritage while it is still protected untouched below the actual surface. Due to recent technical developments in high resolution large scale non-invasive archaeological prospection by the Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology (LBI ArchPro) like motorized multi-channel Ground Penetrating Radar (GPR), multi-sensor Magnetometry or Airborne Remote Sensing it became possible to efficently explore square kilometers of archaeological landscapes in high detail. Using a georeferenced Archaeological Information System (AIS) to compare, combine and interpret the archaeological information embedded within prospection and excavation data enable spatio-temporal analyses to derive the cultural development of an archaeological landscape.Item Color and Hyperspectral Image Segmentation for Historical Documents(IEEE, 2015) Ciortan, Irina Mihaela; Deborah, Hilda; George, Sony; Hardeberg, Jon Yngve; Gabriele Guidi and Roberto Scopigno and Pere BrunetSeveral historical documents from the collection of the National Library of Oslo were acquired using a hyperspectral scanner. While each of the documents has its specific characteristics, requiring different image preprocessing steps, the common goal for all documents is to increase their legibility. The aim of this study is to show the advantage of hyperspectral imaging compared to traditional color imaging, in particular for the task of ink separation using distance-based classification method.Item Etruscan Virtual Experience(IEEE, 2015) Guidazzoli, Antonella; Liguori, Maria Chiara; Luca, Daniele De; Imboden, Silvano; Bellavia, Giovanni; Verri, Luigi; Rivalta, Alessandro; Caraceni, Simona; Sofia Pescarin and Pedro Cano and Alfredo GrandeRecently the Etruscans have gained increasing visibility thanks to various events and initiatives. Cineca Visual Information Techonology laboratory (VisitLab) is active in this effort by developing installations, CG movies and other ICT applications aimed at further raising public awareness of the Etruscan civilisation.Item A New Way to Enrich Museum Experience Through X-ray Tomography The Diagnostic Study of a Wax Anatomical Model of the 18th Century Made by Anna Morandi Manzolini(IEEE, 2015) Peccenini, Eva; Bettuzzi, Matteo; Brancaccio, Rosa; Casali, Franco; Morigi, Maria Pia; Piro, Laura; Lanzarini, Viviana; Todero, Antonio; Leonardi, Luisa; Sequi, Elios; Gabriele Guidi and Roberto Scopigno and Fabio RemondinoThe result of Computed Tomography (CT) investigation consists in a 3D volume of the object able to show its inner parts, revealing hidden structures and materials used in a completely non-invasive way. Its application, in Cultural Heritage field, is an important resource to enhance the knowledge of execution the construction technique and the state of conservation. This work was triggered by a need of diagnostic investigation before the restoration of anatomical wax model of the 18th century made by Anna Morandi Manzolini, kept at the Palazzo Poggi Museum in Bologna, but the peculiarity of the application and its results has yielded new purposes to the diagnostic investigation related to scientific communication and museum fruition. CT analysis was carried out using an experimental CT system specifically designed for the analysis of Cultural Heritage materials, developed by the X-ray imaging research group at the Physics and Astronomy Department of the University of Bologna. The results of the investigation were shown then at the Anatomical Wax Museum ''Luigi Cattaneo'' in Bologna, during the ''Festival of Medical Science. Long Life'', from 7 to 10 May 2015, through a 3D virtual projection.Item Customised OCR Correction for Historical Medical Text(IEEE, 2015) Thompson, Paul; Mcnaught, John; Ananiadou, Sophia; Gabriele Guidi and Roberto Scopigno and Fabio RemondinoHistorical text archives constitute a rich and diverse source of information, which is becoming increasingly readily accessible, owing to large-scale digitisation efforts. Searchable access is typically provided by applying Optical Character Recognition (OCR) software to scanned page images. Often, however, the automatically recognised text contains a large number of errors, since OCR systems are typically optimised to deal with modern documents, and can struggle with historical document features, including variable print characteristics and archaic vocabulary usage. Low quality OCR text can reduce the efficiency of search systems over historical archives, particularly semantic systems that are based on the application of sophisticated text mining (TM) techniques. We report on a new OCR correction strategy, customised for historical medical documents. The method combines rule-based correction of regular errors with a medically-tuned spellchecking strategy, whose corrections are guided by information about subject-specific language usage from the publication period of the article to be corrected. The performance of our method compares favourably to other OCR post-correction strategies, in improving word-level accuracy of poor-quality documents by up to 16%.Item Engaging and Shared Gesture-based Interaction for Museums - The Case Study of K2R International Expo in Rome(IEEE, 2015) Fanini, Bruno; D'Annibale, Enzo; Demetrescu, Emanuel; Pagano, Alfonsina; Ferdani, Daniele; Gabriele Guidi and Roberto Scopigno and Pere BrunetThis paper presents a full life-cycle production and standardized workflow to deploy a shared and engaging gesturebased experience within a museum, connecting two different natural interaction applications. The research presented in this paper is specifically focused on Admotum and Holoint, two gesture-based applications developed for the V-Must.net in occasion of ''Keys to Rome'' international exhibition on Roman Culture. The workflow described here includes 3D content production, application design, development and integration within flexible museum setups, together with evaluation activities to explore more on the user's' educational benefits and the potential of such collaborative museum experience.Item Mapping Identity with Geo-technology: Montelupo/Italy Versus Santa Leopoldina/Brazil(IEEE, 2015) Andrade, Bruno Amaral de; Almeida, Renata Hermanny de; Gabriele Guidi and Roberto Scopigno and Juan BarcelóThis article is inserted in the hybrid-theme ''Heritage and Representation'', in the field of new methods of iconographic representation of the territorial-landscape heritage, through digital models of cartographic construction. The problematic identified in representations of the territory is solved from an analytical hierarchy of observation, interpretation and comprehension of the relationship between biotic and anthropic dimensions, with consideration of the title role of the ecological aspect of the territory, and its relation to the construction of identity. The hypothesis guides the evaluation and experiment of a consolidated Italian approach and its adoption to the Brazilian context. The objects of empirical study are the cities of Montelupo/Toscany/Italy, and Santa Leopoldina/Espírito Santo/Brazil, as locus to elaborate a comparative method in the environmental heritage category. The aim of this article is revealing how the environmental aspect of the territory is relevant to the construction of identity, through mapping by GIS software.Item Development of a Low-Cost Application of Virtual Reality for the Promotion of Cultural Heritage(IEEE, 2015) Esclapés, Javier; Tejerina, Daniel; Martín, Alejandro; Fabregat, Laia; Gabriele Guidi and Roberto Scopigno and Pere BrunetThis paper shows the state of a research about cultural heritage whose main purpose is to allow the user to move virtually to any place of cultural or architectonic interest that, either for economic or accessibility reasons, is very difficult or impossible to visit.Item Intangible Treasures - Capturing the Intangible Cultural Heritage and Learning the Rare Know-How of Living Human Treasures(IEEE, 2015) Grammalidis, Nikos; Dimitropoulos, Kosmas; Sofia Pescarin and Pedro Cano and Alfredo Grandei-Treasures project, included into EU FP7, aims at building a public and expandable platform to enable learning and transmission of rare know-how of Intangible Cultural Heritage (ICH) in order to prevent them from extinction.I-Treasure aims to provide a tool that will allow their transmission to new people. The proposed platform combines lots of different technologies like multisensory technology, singing voice synthesis and sensorimotor learning to leave the beaten path in education and ICH knowledge transmission. In i-Treasures project, there are four main ICH cases: rare traditional songs; rare dance interactions; traditional craftsmanship focusing on the art of pottery making, and finally contemporary music composition based on Beethoven, Haydn and Mozart musical pieces.Item The Lion's Gate and the Persian Wall in Byblos - Opening the Doors of Digital Representation to the Cultural Heritage of a Resilient City in Lebanon(IEEE, 2015) Garagnani, Simone; Bravo, Luisa; Madrigal, José Manuel Pagés; Gabriele Guidi and Roberto Scopigno and Pere BrunetByblos, modern Jbeil, is a northern Lebanese city considered as one of the oldest continuously inhabited cities since Neolithic times, designated as a UNESCO World Heritage site in 1984. Thus, the archaeological area, strictly surrounded by city boundaries, is the result of several civilizations that came over the centuries producing many layers of architectural buildings now in precarious state of conservation. The recent nomination of Byblos as one of the ''100 Resilient Cities'', a project pioneered by the Rockefeller Foundation, fostered some new intents aimed at the preservation of the urban space and the archaeological site. In order to support a possible valorization strategy, the Lion's Gate at the Persian Wall has been chosen as a case study to experiment how digital photogrammetric modeling of meaningful remains can improve dissemination of cultural legacy to remote visitors and transfer knowledge to town planners. This paper presents the preliminary research, which is supposed to be integrated by some more detailed surveys in the near future, in order to populate a shared web repository in which scholars, tourists and planners will find useful information on the archaeological park.Item Exploration of the Changing Structure of Cities: Challenges for Temporal City Models(IEEE, 2015) Périnaud, Clémentine; Gesquière, Gilles; Gay, Georges; Gabriele Guidi and Roberto Scopigno and Juan BarcelóThe ALARIC project (Incremental Urban Change Research Project) is dedicated to the production of geo-historical information concerning two formerly industrial cities of the Lyon-Saint-Etienne region (19th and 20th century). The explo-ration of the incremental nature of urban change implies identifying when certain historical processes took place, such as the shift from one-off to systematic construction and changes in urban planning strategies. Specifically, the case stu-dy investigates the emergence of local urban projects to compare the transformation processes of the urban fabric and to specify the pace of urban change. Historical records will be accessed through a virtual mapping environment based on the temporal reconstitution of cities in two dimensions, and sometimes for special cases in three dimensions. This paper presents methodological principles to reconstruct former cities in order to inquire urban change and requirements for effective sharing of hypotheses on the various states of the past urban landscape and associated transformation processes.Item Precise 3D Recording for Finite Element Analysis(IEEE, 2015) Kalisperakis, Ilias; Stentoumis, Christos; Grammatikopoulos, Lazaros; Dasiou, Maria Eleni; Psycharis, Ioannis N.; Gabriele Guidi and Roberto Scopigno and Juan BarcelóLately, 3D laser scanning and Photogrammetry are becoming a standard in Cultural Heritage recording. In this contribution, a combination of both methods is presented for the precise 3D geometric documentation of a plaster copy of a Greek statue from the archeological site of Delos. The 3D model was generated for the structural assessment of the original statue and its supporting mechanism via finite element analysis (FEA).Item Interdisciplinary Workflow for Virtual Archaeology(IEEE, 2015) Luznik, Nika; Klein, Michael; Gabriele Guidi and Roberto Scopigno and Juan BarcelóThere is an increasing trend to present cultural heritage with the help of virtual visualisation. It offers a unique level of understanding of the heritage in question. Moreover, depending on the precision of the virtual model, it can be used for scientific research, and it can inspire new ideas and conclusions about the actual looks of the visualised objects. Over the years, companies and institutions have specialized in this field of work, creating new demands on the CG artists of the involved teams, as well as establishing a new kind of archaeological methodology that seeks to research and develop ways of using computer-based visualisation for the comprehensive management of archaeological heritage. However, the interpretation of archaeological datasets and their subsequent transformation into 3D representations of the interpretation usually requires a timeconsuming process of re-evaluation and discussion. Very often, a discrepancy between scientific architectural interpretation that is normally presented in a 2D plane and its realisation in a 3D space occurs, because the 2D representation is not able to show the physical laws of the third dimension. To overcome these difficulties, we propose alternative solutions that lessen the disconnection between the parties. Our software solution enables the archaeologist to perform an interpretative work-flow that places ideas within a customizable 3D environment, therefore resulting in a more direct involvement throughout the reconstructive or representative process. On a broader scale, CGI artists would benefit greatly if they could follow the project evolving and gain a deeper understanding of the specific cultural heritage.Item Marco Cappellini Uffizi(IEEE, 2015) Rocco, Paolo de; Cappellini, Marco; Romoli, Paolo; Sofia Pescarin and Pedro Cano and Alfredo GrandeUffizi Touch Cloud is a cloud service that can be accessed through an interactive whiteboard at schools or at other educational institutions.Item ARIS - A Robotic Approach to Digitization of Indoor and Underground Cultural Heritage Sites(IEEE, 2015) Calisi, Daniele; Giannone, Francesca; Ventura, Claudia; Salonia, Paolo; Cottefoglie, Fabio; Ziparo, Vittorio Amos; Sofia Pescarin and Pedro Cano and Alfredo GrandeA robot to digitize indoor and underground cultural heritage sites: a novel approach for acquiring and managing digital models of archaeological sites. Three technologies will be presented for this occasion: a robotic system for digitization of archaeological sites (DigiRo), a cloud-based archaeological information system (ARIS), and an immersive virtual reality apps for virtually visiting the digitized sites.Item Time-based Database for Creation of Korean Traditional Wooden Building(IEEE, 2015) Lee, Jongwook; Lee, Jihyung; Kim, Jae Woo; Kang, Kyung-Kyu; Lee, Man Hee; Goo, Boncheol; Gabriele Guidi and Roberto Scopigno and Juan Barcelóthis paper is designed to define and categorize the architectural components of the Korean traditional buildings on the basis of their time periods. By incorporating the time-based criteria and component relations into the existing data-base, this study is expected to improve time and accuracy in reconstructing and remodeling the Korean traditional wooden buildings.
