    An Analytics System for the Evaluation of Interactions of Museum Visitors in Augmented Reality Tours
    (Mensch und Computer 2020 - Workshopband, 2020) Ohlei, Alexander; Schumacher, Toni; Herczeg, Michael
    This paper presents the design, implementation, and evaluation of a system that supports the analysis of visitor interactions with augmented reality (AR) content in museum exhibitions. It can be used in conjunction with the AR authoring and presentation system InfoGrid. InfoGrid enables museum professionals to setup indoor and outdoor AR tours by connecting visual features of physical exhibits with different kinds of media. Visitors can retrieve these media by using the InfoGrid mobile app and scanning the target areas. The analytics application presented in this paper aims to help museum professionals to get an understanding of how visitors are using the AR tours they created. It shows how visitors interact with each AR element and reveals if some elements have been unrecognized. It allows museum professionals to visually inspect the data mapped onto a digital floor plan of the museum. The system visualizes movement paths on the floor plan as well as heatmaps that represent the overall time spent in an exhibit. Data for the evaluation system is anonymously generated by using a logging mechanism of the InfoGrid AR mobile app. Finally, we present a usability evaluation of the analytics system, discuss the results as well as future work.

    Capturing the Past: Photogrammetry for Safeguarding Sudanese Cultural Heritage Digitally
    (INFORMATIK 2024, 2024) Abdalhaleem, Duaa; Elkhalifa, Akram A.
    Cultural heritage is a valuable asset for any country, and it is crucial to protect, restore, and preserve it because it is threatened by both nature and human actions. Preservation methods have always been a significant concern, and traditional methods of documentation, such as 2D drawings, pictures, and conventional 3D modelling systems, have proven to be inefficient in terms of cost, time, effort, and quality. However, with advancements in technology and digital transformation, more effective techniques have been developed. One such technique is photogrammetry, which has proven to be a convenient way to digitize cultural heritage. For countries such as Sudan, where rich inheritance is in inevitable danger of ongoing armed conflicts, it is important to preserve this cultural heritage. This paper studies the feasibility of using photogrammetry as a digitalization technique to preserve Sudan’s cultural heritage by reviewing previous experiences and conducting two case studies that investigate the applicability of the technique to non-experts, along with its potential and limitations. Selected objects were digitized using close-range photogrammetry with a low budget and simple equipment. The final outcome was promising, particularly for small and medium-sized objects. Finally, a list of recommendations is provided to facilitate the digitalization of Sudanese cultural heritage to preserve it.

    Integrating the Technologies of Image Processing and Virtual Reality for the Digital Preservation of Disappeared Archaeological Sites
    (INFORMATIK 2024, 2024) Al-Ameen, Zohair; Mahmood, Basim; Al-Sarraf, Abdullah; Alchalabi, Oday
    Tangible historical and cultural assets refer to physical artifacts that can be touched and intergenerationally transferred. This kind of asset is considered the past that the next generations should memorize. One of the issues that archaeologists frequently face is the methods used in digitally restoring disappeared archaeological assets. This is due to their low quality, noisy texture, or uncolored images. On the other hand, the advent of new technologies such as digital image processing (DIP) and virtual reality (VR) makes it palatable to digitalize and sustain tangible historical assets. These technologies are recognized as efficient tools insofar as they can contribute to preserving the heritage of civilizations. Hence, this study suggests an approach that integrates DIP and VR techniques to restore historical assets that have disappeared from low-quality images. The findings show that the proposed methodology is successful in restoring archaeological sites or objects, as demonstrated by the results obtained.

    Photogrammetric Analysis for Accurate Three-Dimensional Reconstruction of the Mudhafaria Minaret in Erbil (Kurdistan Region of Iraq)
    (INFORMATIK 2024, 2024) Mustafa, Sima; Qader, Aland
    This paper presents a photogrammetry-based approach for the digital reconstruction of the Mudhafaria Minaret in Erbil, Kurdistan Region of Iraq. Hundreds of two-dimensional images were transformed into a detailed three-dimensional model of the minaret using photogrammetric methods and software. The photographs were captured from various perspectives, making sure that all angles of the minaret were documented. The data were then uploaded onto specialized software that generated a detailed 3D model. The employment of three-dimensional scanning makes it possible to conserve cultural assets and accurately chronicle historical events with greater ease. Through the use of digital reconstruction, we are able to acquire a more in-depth comprehension of our shared history, as well as a deeper respect for it. In order to achieve this goal, it’s necessary for us to demonstrate that photogrammetry is not only dependable but also flexible for use in the field of cultural heritage.

    Photogrammetry and iPhone LiDAR in Remote Places for Preparation of 3D-Objects in a Virtual Museum
    (INFORMATIK 2024, 2024) Noviana, Eka; Plank, Uli; Wand, Eku
    This is a feasibility study to evaluate acquisition of three-dimensional cultural artefacts for a virtual museum in Indonesia, in particular under difficult conditions regarding transportation, lighting and power supply. Evaluation is done by comparison of the resulting models in a 3D software for size, resolution, and visual realism. In a second step, models are reduced in texture size and mesh resolution, to be tested for real-time playback in FrameVR. Included hardware tools for photogrammetry are high-resolution stills from a hybrid photographic camera, a small drone, and a smartphone with a combination of LiDAR (Light Detection and Ranging) and photography. Generation of 3D models is realised by free software for generation and also for enhancement of results. The results show that the tools can generate realistic models of cultural artefacts under varying environmental conditions and enable playability in a virtual 3D environment.

    (INF-DH-2018, 2018) Niebling, Florian; Münster, Sander; Bruschke, Jonas; Maiwald, Ferdinand; Friedrichs, Kristina
    Forschung in den Digital Humanities (DH) erfordert die Zusammenarbeit verschiedener Disziplinen aus Geistes- und Kultur-, Ingenieur- und Informationswissenschaften. Die Fragestellungen die sich dabei aus geisteswissenschaftlicher Perspektive stellen, werfen dabei auch neue Forschungsfragen gerade für die eher angewandten Teilgebiete der Informatik auf. Wir präsentieren Ergebnisse einer interdisziplinären Nachwuchsforschergruppe, die Medienrepositorien historischer Photographien, Zeichnungen und Plänen um räumlich-zeitliche Zugänge erweitert. Es werden Methoden entwickelt um historische Abbildungen von Gebäuden in ein räumliches und zeitliches Modell einzubringen und dieses für architekturwissenschaftliche Forschung zugänglich zu machen. Am Beispiel Dresdner Stadtgeschichte werden Forschungsfragen der Geschichtswissenschaften, Photogrammetrie, Bildungswissenschaften und verschiedenen Bereichen der Informatik bearbeitet.
