This article aims to explore the processes between YouTube creators and advertisers concerning product placement enquiries. For this purpose, YouTube creators from Germany ( n = 57) answered an online survey about their experiences with advertisers. The creators covered a wide range of YouTube channel genres (beauty, fashion, comedy, gaming, cooking) and differed in number of subscribers. Some creators who took part in the survey had less than 20,000 subscribers, others had between 20,000 and 500,000 subscribers and still others had more than 500,000 subscribers. How often do YouTube creators use product placement? Is paid-for placement an important source of finance for them? How professional are the relations and processes between YouTube creators and advertisers? Before presenting and discussing the results of the empirical survey of the current use of product placement, a brief history of how YouTube has become a marketing space for advertisers is provided.}, language = {en} } @article{Gerhards2025, author = {Gerhards, Claudia}, title = {Social Media Influencers as "Dirty Workers": An Explorative Study on How They Use Strategies to Reduce the Moral Taint}, series = {Social Media + Society}, volume = {11}, journal = {Social Media + Society}, number = {2}, publisher = {SAGE Publications}, issn = {2056-3051}, doi = {10.1177/20563051251348917}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-54189}, pages = {17}, year = {2025}, abstract = {Since social media influencers have become popular and monetize their content with the help of advertising deals, they have been associated with morally questionable, deceptive behavior. The list of misconduct is long. It includes, for example, not disclosing sponsored content, withholding negative experiences with promoted products, buying fake followers, and promoting false ideals of beauty. Building on the concept of "dirty work" as a theoretical framework, this article asks which strategies influencers use to soften this moral taint. Qualitative interviews with influencers living in Germany show that they are aware of their negative image in public and use various stigma management strategies. This article offers a perspective that has not yet played a role in the ethics debate about influencers. It asks how influencers, who are often associated with morally questionable practices, immunize themselves against this negative image and find a positive work identity.}, language = {en} } @article{GeneralBobrowskiPoehleretal.2015, author = {General, S. and Bobrowski, N. and P{\"o}hler, D. and Weber, Konradin and Fischer, C. and Platt, U.}, title = {Airborne I-DOAS measurements at Mt.

Traditional archers aim without a target figure. Good shooting results require an excellent body-eye coordination that allows the user to perform identical movements when drawing the bow. Our simulator provides a virtual archery experience and supports the user to learn and practice the motion sequence of traditional archery in a virtual environment. We use an infrared tracking system to capture the user's movements in order to correct his movement. To provide a realistic haptic feedback a real bow is used as interaction device. Our system provides a believable user experience and supports the user to learn how to shoot in the traditional way. Following a user-centered iterative design approach we developed a number of prototypes and evaluated them for refinement in sequent iteration cycles. For illustration purposes we created a short video clip in our virtual studio about this project that presents the main ideas in an informative yet entertaining way.}, language = {en} } @inproceedings{GeigerFritzeLehmannetal.2008, author = {Geiger, Christian and Fritze, Robin and Lehmann, Anke and St{\"o}cklein, J{\"o}rg}, title = {HYUI: a visual framework for prototyping hybrid user interfaces}, series = {Proceedings of the 2nd international conference on Tangible and embedded interaction - TEI '08, 18.02.2008 - 20.02.2008, Bonn}, booktitle = {Proceedings of the 2nd international conference on Tangible and embedded interaction - TEI '08, 18.02.2008 - 20.02.2008, Bonn}, editor = {Schmidt, Albrecht and Gellersen, Hans and van den Hoven, Elise and Mazalek, Ali and Holleis, Paul and Villar, Nicolas}, publisher = {ACM Press}, address = {New York}, isbn = {9781605580043}, doi = {10.1145/1347390.1347406}, pages = {63}, year = {2008}, language = {en} } @inproceedings{GeigerAliDilchert2025, author = {Geiger, Christian and Ali, Soren and Dilchert, Philipp}, title = {The BildKlangPoet - a technical framework for designing mixed reality painting experiences using generative AI}, series = {KUI 2025: XXII.
