  abstract  = {Die vorliegende Arbeit l{\"a}sst sich dem Bereich der quantitativen Literaturanalyse zuordnen und verfolgt das Ziel, mittels computergest{\"u}tzter Verfahren zu untersuchen, inwieweit sich Romane hinsichtlich ihrer Figurenkonstellation {\"a}hneln. Dazu wird die Figurenkonstellation, als wichtiges strukturgebendes Ordnungsprinzip eines Romans, als soziales Netzwerk der Figuren operationalisiert. Solche Netzwerke k{\"o}nnen unter Anwendung von Verfahren des Natural Language Processing automatisch aus dem Text erstellt werden. Als Datengrundlage dient ein Korpus von deutschsprachigen Romanen aus dem 19. Jahrhundert, das mit automatischen Verfahren zur Figurenerkennung und Koreferenzaufl{\"o}sung prozessiert und manuell nachkorrigiert wurde, um eine m{\"o}glichst saubere Datenbasis zu schaffen. Ausgehend von der intensiven vergleichenden Betrachtung der Figurenkonstellationen von Fontanes "Effi Briest" und Flauberts "Madame Bovary" wurde in einer manuell erstellten Distanzmatrix die menschliche Intuition solcher {\"A}hnlichkeit zwischen allen Romanen des Korpus festgehalten, basierend auf der Lekt{\"u}re von Zusammenfassungen der Romane. Diese Daten werden als Evaluationsgrundlage genutzt. Mit Hilfe von Methoden der sozialen Netzwerkanalyse k{\"o}nnen strukturelle Eigenschaften dieser Netzwerke als Features erhoben werden. Diese wurden anschließend zur Berechnung der Kosinusdistanz zwischen den Romanen verwendet. Obwohl die automatisch erstellten Netzwerke die Figurenkonstellationen der Romane im Allgemeinen gut widerspiegeln und die Netzwerkfeatures sinnvoll interpretierbar sind, war die Korrelation mit der Evaluationsgrundlage niedrig. Dies legt die Vermutung nahe, dass neben der Struktur der Figurenkonstellation auch wiederkehrende Themen und Motive die Erstellung der Evaluationsgrundlage unterbewusst beeinflusst haben. Daher wurde Topic Modeling angewendet, um wichtige zwischenmenschliche Motive zu modellieren, die f{\"u}r die Figurenkonstellation von Bedeutung sein k{\"o}nnen. Die Netzwerkfeatures und die Topic-Verteilung wurden in Kombination zur Distanzberechnung herangezogen. Außerdem wurde versucht, jeder Kante des Figurennetzwerks ein Topic zuzuordnen, das diese Kante inhaltlich beschreibt. Hier zeigte sich, dass einerseits Topics, die sehr spezifisch f{\"u}r bestimmte Texte sind, und andererseits Topics, die {\"u}ber alle Texte hinweg stark vertreten sind, das Ergebnis bestimmen, sodass wiederum keine, bzw. nur eine sehr schwache Korrelation mit der Evaluationsgrundlage gefunden werden konnte. Der Umstand, dass keine Verbindung zwischen den berechneten Distanzen und der Evaluationsgrundlage gefunden werden konnte, obwohl die einzelnen Features sinnvoll interpretierbar sind, l{\"a}sst Zweifel an der Evaluationsmatrix aufkommen. Diese scheint st{\"a}rker als zu Beginn angenommen unterbewusst von thematischen und motivischen {\"A}hnlichkeiten zwischen den Romanen beeinflusst zu sein. Auch die Qualit{\"a}t der jeweiligen Zusammenfassung hat hier einen nicht unwesentlichen Einfluss. Daher w{\"a}re eine weniger subjektiv gepr{\"a}gte M{\"o}glichkeit der Auswertung von N{\"o}ten, beispielsweise durch die parallele Einsch{\"a}tzung mehrerer Annotatoren. Auch die weitere Verbesserung von NLP-Verfahren f{\"u}r literarische Texte in deutscher Sprache ist ein Desideratum f{\"u}r ankn{\"u}pfende Forschungsans{\"a}tze.},

  abstract  = {Software frameworks for Realtime Interactive Systems (RIS), e.g., in the areas of Virtual, Augmented, and Mixed Reality (VR, AR, and MR) or computer games, facilitate a multitude of functionalities by coupling diverse software modules. In this context, no uniform methodology for coupling these modules does exist; instead various purpose-built solutions have been proposed. As a consequence, important software qualities, such as maintainability, reusability, and adaptability, are impeded. Many modern systems provide additional support for the integration of Artificial Intelligence (AI) methods to create so called intelligent virtual environments. These methods exacerbate the above-mentioned problem of coupling software modules in the thus created Intelligent Realtime Interactive Systems (IRIS) even more. This, on the one hand, is due to the commonly applied specialized data structures and asynchronous execution schemes, and the requirement for high consistency regarding content-wise coupled but functionally decoupled forms of data representation on the other. This work proposes an approach to decoupling software modules in IRIS, which is based on the abstraction of architecture elements using a semantic Knowledge Representation Layer (KRL). The layer facilitates decoupling the required modules, provides a means for ensuring interface compatibility and consistency, and in the end constitutes an interface for symbolic AI methods.},

While these technologies are widely explored in entertainment games, they also offer possibilities for educational use. However,their uptake in education is so far very limited. Within the ImTech4Ed project, we aim at systematically exploring the power of interdisciplinary, international hackathons as a novel method to create immersive educational game prototypes and as a means to transfer these innovative technical prototypes into educational use. To achieve this, we bring together game design and development, where immersive and interactive solutions are designed and developed; computer science, where the technological foundations for immersive technologies and for scalable architectures for these are created; and teacher education, where future teachers are educated. This article reports on the concept and design of these hackathons.},

  abstract  = {Optical Character Recognition (OCR) on historical printings is a challenging task mainly due to the complexity of the layout and the highly variant typography. Nevertheless, in the last few years, great progress has been made in the area of historical OCR, resulting in several powerful open-source tools for preprocessing, layout analysis and segmentation, character recognition, and post-processing. The drawback of these tools often is their limited applicability by non-technical users like humanist scholars and in particular the combined use of several tools in a workflow. In this paper, we present an open-source OCR software called OCR4all, which combines state-of-the-art OCR components and continuous model training into a comprehensive workflow. While a variety of materials can already be processed fully automatically, books with more complex layouts require manual intervention by the users. This is mostly due to the fact that the required ground truth for training stronger mixed models (for segmentation, as well as text recognition) is not available, yet, neither in the desired quantity nor quality. To deal with this issue in the short run, OCR4all offers a comfortable GUI that allows error corrections not only in the final output, but already in early stages to minimize error propagations. In the long run, this constant manual correction produces large quantities of valuable, high quality training material, which can be used to improve fully automatic approaches. Further on, extensive configuration capabilities are provided to set the degree of automation of the workflow and to make adaptations to the carefully selected default parameters for specific printings, if necessary. During experiments, the fully automated application on 19th Century novels showed that OCR4all can considerably outperform the commercial state-of-the-art tool ABBYY Finereader on moderate layouts if suitably pretrained mixed OCR models are available. Furthermore, on very complex early printed books, even users with minimal or no experience were able to capture the text with manageable effort and great quality, achieving excellent Character Error Rates (CERs) below 0.5\%. The architecture of OCR4all allows the easy integration (or substitution) of newly developed tools for its main components by standardized interfaces like PageXML, thus aiming at continual higher automation for historical printings.},

  abstract  = {Slot machines are one of the most played games by players suffering from gambling disorder. New technologies like immersive Virtual Reality (VR) offer more possibilities to exploit erroneous beliefs in the context of gambling. Recent research indicates a higher risk potential when playing a slot machine in VR than on desktop. To continue this investigation, we evaluate the effects of providing different degrees of embodiment, i.e., minimal and full embodiment. The avatars used for the full embodiment further differ in their appearance, i.e., they elicit a high or a low socio-economic status. The virtual environment (VE) design can cause a potential influence on the overall gambling behavior. Thus, we also embed the slot machine in two different VEs that differ in their emotional design: a colorful underwater playground environment and a virtual counterpart of our lab. These design considerations resulted in four different versions of the same VR slot machine: 1) full embodiment with high socio-economic status, 2) full embodiment with low socio-economic status, 3) minimal embodiment playground VE, and 4) minimal embodiment laboratory VE. Both full embodiment versions also used the playground VE. We determine the risk potential by logging gambling frequency as well as stake size, and measuring harm-inducing factors, i.e., dissociation, urge to gamble, dark flow, and illusion of control, using questionnaires. Following a between groups experimental design, 82 participants played for 20 game rounds one of the four versions. We recruited our sample from the students enrolled at the University of W{\"u}rzburg. Our safety protocol ensured that only participants without any recent gambling activity took part in the experiment. In this comparative user study, we found no effect of the embodiment nor VE design on neither the gambling frequency, stake sizes, nor risk potential. However, our results provide further support for the hypothesis of the higher visual angle on gambling stimuli and hence the increased emotional response being the true cause for the higher risk potential.},

  abstract  = {In recent years, the applications and accessibility of Virtual Reality (VR) for the healthcare sector have continued to grow. However, so far, most VR applications are only relevant in research settings. Information about what healthcare professionals would need to independently integrate VR applications into their daily working routines is missing. The actual needs and concerns of the people who work in the healthcare sector are often disregarded in the development of VR applications, even though they are the ones who are supposed to use them in practice. By means of this study, we systematically involve health professionals in the development process of VR applications. In particular, we conducted an online survey with 102 healthcare professionals based on a video prototype which demonstrates a software platform that allows them to create and utilise VR experiences on their own. For this study, we adapted and extended the Technology Acceptance Model (TAM). The survey focused on the perceived usefulness and the ease of use of such a platform, as well as the attitude and ethical concerns the users might have. The results show a generally positive attitude toward such a software platform. The users can imagine various use cases in different health domains. However, the perceived usefulness is tied to the actual ease of use of the platform and sufficient support for learning and working with the platform. In the discussion, we explain how these results can be generalized to facilitate the integration of VR in healthcare practice.},
