    360-degree Models in Environmental Engineering Education: an Explorative Case Study
    (DELFI 2020 – Die 18. Fachtagung Bildungstechnologien der Gesellschaft für Informatik e.V., 2020) Wolf, Mario; Söbke, Heinrich; Wehking, Florian; Hörnlein, Stefanie
    360-degree models are defined as the algorithmic merging of multiple 360-degree images of an enclosed space creating a single visual model of the space that can be viewed from various positions within the space. As means of virtual reality, 360-degree models can be understood as a medium with impact on learning. Aiming at evaluating the educational potential of 360-degree models in the field of environmental engineering, an explorative pilot study featuring an innovative sanitation system has been conducted (N=17). Quantitative measurements of motivation, emotion and usability show positive results. Guided interviews revealed both key points and problems to be addressed. Although the learning efficiency is still to be validated, the study renders 360-degree models as promising learning tools that might enrich tertiary education in environmental engineering.

    Authoring Educational 360° Models
    (Proceedings of DELFI Workshops 2022, 2022) Wehking, Florian; Wolf, Mario; Söbke, Heinrich
    The continuous progress of 360° technologies in recent years has considerably reduced the effort required for creating 360° models. Educational 360° models may now be authored by instructors themselves. However, the quality and usability of 360° models still depend significantly on experience gained from previous authoring of 360° models. Thus, this article summarizes the experience gained during authoring of eleven 360° models from 2018 to 2022 for higher education in environmental engineering. The experiences are structured following a process model inspired by Wohl 2019. Four cameras and four software packages have been used for authoring the eleven 360° models. Based on the eleven 360° models, authoring principles and generalizable experiences are provided to guide the selection of approaches and design elements, as well as hardware and software equipment, for authoring of 360° models.

    Flucht aus dem Wasserwerk - Ein niedrigschwelliger edukativer 360°-VR Escape Room
    (Wettbewerbsband AVRiL 2022, 2022) Wehking, Florian; Wolf, Mario; Söbke, Heinrich; Springer Christian
    Exkursionen sind als wertvolle Lernaktivitäten auch in Disziplinen der bebauten Umwelt, wie Bau- und Umweltingenieurwesen etabliert. Um vorhandene Nachteile wie hohe Aufwände auszugleichen, werden Exkursionen auch virtualisiert, u.a. mit 360°-Technologie. Dieser Beitrag stellt ein Lernsze-nario vor, in dem das 360°-Modell eines Wasserwerkes mit einem Escape Room ergänzt wird, um zum einen Führung durch das 360°-Modell bereitzustellen und zum anderen zu einem motivierenden Lernerlebnis beizutragen. Erste Evaluationen kennzeichnen das Lernszenario als mit wenig Aufwand transferierbar und lassen es einen Platz zwischen konventionellen theoriebasierten Lernaktivitäten und Exkursion einnehmen.

    High Accuracy GPS Antennas in Educational Location-based Augmented Reality
    (Proceedings of DELFI Workshops 2022, 2022) Osipova, Margarita; Das, Sanghamitra; Riyad, Peter; Söbke, Heinrich; Wolf, Mario; Wehking, Florian
    In location-based augmented reality (AR), the augmentations depend on the geolocation. Location-based AR might be used in higher education for enabling authentic learning experiences. However, the positioning accuracy achievable with GPS receivers built into off-the-shelf mobile devices has been shown in previous studies to be suboptimal for a subset of learning scenarios. Accordingly, in this comparative study, we investigated whether high accuracy GPS antennas are capable of achieving higher positioning accuracy, which also may improve the learning experience. Specifically, a mobile geographical information system (GIS) client (AugView) was used to visual-ize pipes and manholes in the underground. Participants were tasked with recording a local sewer system using the GIS client and subsequently visualizing the network using the GIS client’s AR mode. The experimental group (N=8) used an external GPS antenna, while the control group (N=8) relied on the standard GPS receivers of the mobile device. Usability was assessed using the Post-Study System Usability Questionnaire, learning outcomes were measured using pre- and post-test. In addition, semi-structured interviews were conducted with all participants. As a result, usability and learning outcomes were found to be better for the experimental group, but deficits in accuracy of the visualizations were also found with the GPS antenna. In particular, the time delay that must be waited until a high accuracy is achieved in case of non-uniform motion has to be noted. However, this time delay can be compensated for with appropriate learning scenarios design. In summary, high accuracy GPS antennas seem being beneficial to learning scenarios but require careful context-spe-cific prior evaluation.

    How to Record 360-degree Videos of Field Trips for Education in Civil Engineering
    (Proceedings of DELFI Workshops 2019, 2019) Wehking, Florian; Wolf, Mario; Söbke, Heinrich; Londong, Jörg
    As part of Virtual Reality, 360-degree videos have potential to enhance tertiary education. One application area is the documentation of field trips in the discipline of civil engineering. Field trips are usually organized infrequently, with shifting motives and are limited to small groups of students. 360-degree videos share the experiences of field trips with a wider student-audience. However, recording 360-degree videos requires careful preparations. Therefore, the paper addresses the issue how 360-videos should be recorded for usage as supportive medium in educational contexts. Based on a literature research the authors compile a set of recommendations and verify it through two case studies in Bangladesh. The aim of the paper is to enable educational stakeholders to record elaborated 360-degree videos to enrich tertiary education in civil engineering by a promising medium of learning

    Mixed Reality zur Qualifikation in der räumlichen Planung
    (Proceedings of DELFI Workshops 2019, 2019) Wolf, Mario; Wehking, Florian; Söbke, Heinrich; Londong, Jörg
    In den vergangenen Jahren hat Mixed Reality (MR) zunehmend Einzug in Lehrkontexte gehalten. Anwendungsfälle von MR in der räumlichen Planung und sich daraus ergebende Lehr- und Lerneffekte sind bisher aber kaum bekannt. Doch welche Potenziale können MR-Anwendungen in Lehrkontexten der räumlichen Planung haben? Zur Beantwortung dieser Frage erfolgt in dem Beitrag aufbauend auf einer theoretischen Betrachtung der Vorteile von MR in Lehrkontexten eine inhaltliche Darlegung existierender raumplanerischer MR-Anwendungen. Abschließend wird der Mehrwert von MR-Anwendungen im raumplanerischen Lehrkontext für Lernende abgeleitet. Grundlage bildet ein integrierter Ansatz, der neben einer Literaturrecherche und der Analyse von MR-Anwendungen auch Praxiserfahrungen der Autoren einschließt.
