Yet the conditions under which such augmentations yield positive experience remain unclear. In this study, we tested whether the experience of being augmented depends on compatibility with the given task. In a between-subject experimental vignette study (N=120 experienced VR users), participants watched first-person videos in one of three conditions: (1) reality-oriented object manipulation (control), (2) task-compatible augmentation (growing/shrinking), or (3) non-task-compatible augmentation (distant grasping). As expected, the augmentation-oriented design only led to a greater sense of augmentation when it was compatible with the task. In turn, the experience of augmentation was positively related to positive affect, need fulfillment, and hedonic quality. These findings suggest that unreal augmentations are beneficial, but only when the new abilities match the task.}, subject = {Virtuelle Realit{\"a}t}, language = {en} } @article{JacquotJuergenSchumannetal.2011, author = {Jacquot, Alexandre and J{\"u}rgen, Thomas and Schumann, Joachim and J{\"a}gle, Martin and B{\"o}ttner, Harald and Gemming, Thomas and Schmidt, J{\"u}rgen and Ebling, Dirk}, title = {(Bi,Sb) 2 Te 3 -PbTe chalcogenide alloys: Impact of the cooling rate and sintering parameters on the microstructures and thermoelectric performances}, series = {Journal of Materials Research}, volume = {26}, journal = {Journal of Materials Research}, number = {15}, publisher = {Cambridge University Press}, doi = {10.1557/jmr.2011.78}, pages = {1773 -- 1784}, year = {2011}, language = {en} } @periodical{OPUS4-5477, title = {14th International Conference on Computational Heat and Mass Transfer}, series = {Heat and Mass Transfer}, journal = {Heat and Mass Transfer}, editor = {Benim, Ali Cemal}, publisher = {Springer Nature}, issn = {1432-1181}, year = {2025}, subject = {Numerische Str{\"o}mungssimulation}, language = {en} } @inproceedings{WeilerStruzekMuelleretal.2024, author = {Weiler, Tim and Struzek, David and M{\"u}ller, Claudia and Huldtgren, Alina and Klapperich, Holger and Grosskopp, Sabrina and Fischer, Florian and Osterheider, Angela and Gaertner, Wanda}, title = {2nd International Workshop on Co-Creation of Hybrid Interactive Systems for Healthcare: Integrating Interdisciplinary and Interprofessional Perspectives in Healthcare Innovation}, series = {Mensch und Computer 2024 - Workshopband}, booktitle = {Mensch und Computer 2024 - Workshopband}, publisher = {Gesellschaft f{\"u}r Informatik e.V.}, doi = {10.18420/muc2024-mci-ws03-120}, pages = {5}, year = {2024}, abstract = {Recent advancements in data science and AI-driven healthcare technologies are bringing up novel opportunities for innovations, such as personalized medicine, self diagnostic tools for everyday use, or hybrid healthcare models. However, the development of these technologies often overlooks the perspectives of patients and their families and socio-cultural surroundings, posing significant social, technological, and ethical challenges related to data bias, empowerment or surveillance, respectively. Bringing together interdisciplinary, interprofessional, and intersectoral collaboration in a systematic way seems to be a crucial element for adressing these issues and ensuring the meaningful integration of sensitive data and AI technologies into patient-centred healthcare arrangements. In this workshop, researchers and practitioners from diverse related disciplines, including HCI, AI, social and cultural sciences, healthcare, gerontology, etc., are invited to share their case studies on innovative health technologies and medical AI. Drawing from contextual best practices, as well as challenges and failures, the workshop organizers aim to collectively devise a systematic approach for co-designing and implementing telemedical innovations in real-world healthcare settings.}, subject = {K{\"u}nstliche Intelligenz}, language = {en} } @inproceedings{BaranowskiUtzigFischeretal.2018, author = {Baranowski, Artur and Utzig, Sebastian and Fischer, Philipp and Gerndt, Andreas and Herder, Jens}, title = {3D spacecraft configuration using immersive AR technology}, series = {Workshop Proceedings / Tagungsband: Virtuelle und Erweiterte Realit{\"a}t - 15.

The spacecraft design process relies on expertise in many domains, such as thermal and structural engineering. The various subsystems of a spacecraft are highly interdependent and have differing requirements and constraints. In this context, interactive visualizations play an important role in making expert knowledge accessible. Recent immersive display technologies offer new ways of presenting and interacting with computer-generated content. Possibilities and challenges for spacecraft configuration employing these technologies are explored and discussed. A user interface design for an application using the Microsoft HoloLens is proposed. To this end, techniques for selecting a spacecraft component and manipulating its position and orientation in 3D space are developed and evaluated. Thus, advantages and limitations of this approach to spacecraft configuration are revealed and discussed.}, language = {en} } @article{DahmBarnjakHeilemann2016, author = {Dahm, Markus and Barnjak, Frano and Heilemann, Moritz}, title = {5Code - An Integrated Programming Environment for Beginners}, series = {i-com: Journal of Interactive Media}, volume = {15}, journal = {i-com: Journal of Interactive Media}, number = {1}, issn = {2196-6826}, doi = {10.1515/icom-2016-0002}, pages = {79 -- 92}, year = {2016}, abstract = {Based on experience in teaching programming, we developed the integrated development environment (IDE) 5Code especially to support beginners. As a first step, a simple, understandable formula was developed how to advance from the problem to the program in 5 operative steps: read it → get it → think it → note it → code it. In order to reduce the cognitive load of the learners effectively, 5Code was designed such that all 5 steps are permanently presented, accessible and executable. Thus, learners are provided with the entire programming context from presentation of the task via own notes and annotations to the code area. Learners can mark and annotate any part of the given task's text; these annotations can be edited as notes with own comments. Furthermore, the notes can be dragged into the code area, where they are shown as comments in the coding language. Any modifications in the comments are synchronized between notes and code. 5Code is implemented as a web-application. It is used in university introductory courses on object oriented programming.}, language = {en} } @article{BrinkmannAspoeckAckermannetal.2021, author = {Brinkmann, Fabian and Asp{\"o}ck, Lukas and Ackermann, David and Opdam, Rob and Vorl{\"a}nder, Michael and Weinzierl, Stefan}, title = {A benchmark for room acoustical simulation.
