Our intention is to improve interaction with virtual objects in a virtual set, which are usually not directly visible to the actor, but only on distant displays. Vibrotactile feedback might improve the appearance on tv because an actor is able to look in any desired direction (camera or virtual object) or to read text on a teleprompter while interacting with a virtual object. Visual feedback in a virtual studio lacks spatial relation to the actor, which impedes the adjustment of the desired interaction. The five tactors of the implemented system which are mounted on the tracked arm give additional information like collision, navigation and activation. The user study for the developed system shows that the duration for reaching a certain target is much longer in case no visual feedback is given, but the accuracy is similar. In this study, subjects reported that an activation signal indicating the arrival at the target of a drag \& drop task was helpful.

Virtual sets typically use static virtual elements or animated objects with predefined behavior so that actors can practice their performance and errors can be corrected in the post production. With the demand for inexpensive live recording and interactive TV productions, virtual objects will be dynamically rendered at arbitrary positions that cannot be predicted by the actor. Perceptive aids have to be employed to support a natural interaction with these objects. In our work we study the effect of haptic feedback for a simple form of interaction. Actors are equipped with a custom built haptic belt and get vibrotactile feedback during a small navigational task (path following). We present a prototype of a wireless vibrotactile feedback device and a small framework for evaluating haptic feedback in a virtual set environment.

Numerous models have been proposed in human-computer interaction (HCI) to guide research and analyze effects. However, bridging the gap between experimental data and real-world applications often proves to be difficult. In the last decades, post-cognitivistic approaches have been developed to explain human cognition and the relation between humans and their environment. In this paper, we present a novel framework to systematically describe and analyze challenges in the context of HCI from multiple perspectives. It extends Cultural-Historical Activity Theory (CHAT) and is enriched by contemporary philosophical perspectives (enactivism, pattern theory of self and post-phenomenology). The proposed framework is further illustrated by applying it to an immersive telementoring prototype system.}, subject = {Mensch-Maschine-Kommunikation}, language = {en} } @incollection{DružetićVogelTischerVogeletal.2025, author = {Družetić-Vogel, Ivana and Tischer, Kim and Vogel, Christoph and Kruse, Patrick and Bertram, Michael and Geiger, Christian}, title = {Playing Through the Past: AR and Gamification in the Cultural Heritage Tour Meppen 1638}, series = {Extended Reality: International Conference, XR Salento 2025, Otranto, Italy, June 17-20, 2025, Proceedings, Part V}, volume = {Lecture Notes in Computer Science 15741}, booktitle = {Extended Reality: International Conference, XR Salento 2025, Otranto, Italy, June 17-20, 2025, Proceedings, Part V}, editor = {De Paolis, Lucio Tommaso and Arpaia, Pasquale and Sacco, Marco}, publisher = {Springer Nature Switzerland}, address = {Cham}, isbn = {9783031977749}, issn = {0302-9743}, doi = {10.1007/978-3-031-97775-6_6}, pages = {95 -- 115}, year = {2025}, subject = {Erweiterte Realit{\"a}t (Informatik)}, language = {en} } @incollection{TriebusHarthDruzeticVogeletal.2025, author = {Triebus, Charlotte and Harth, Jonathan and Druzetic-Vogel, Ivana and Geiger, Christian}, title = {From Tool to Space: Towards Classifying New Media Art}, series = {Extended Reality: International Conference, XR Salento 2025, Otranto, Italy, June 17-20, 2025, Proceedings, Part V}, volume = {Lecture Notes in Computer Science, Bd.15741}, booktitle = {Extended Reality: International Conference, XR Salento 2025, Otranto, Italy, June 17-20, 2025, Proceedings, Part V}, editor = {De Paolis, Lucio Tommaso and Arpaia, Pasquale and Sacco, Marco}, publisher = {Springer Nature Switzerland}, address = {Cham}, isbn = {9783031977749}, issn = {0302-9743}, doi = {10.1007/978-3-031-97775-6_10}, pages = {171 -- 191}, year = {2025}, subject = {Medienkunst}, 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.
