Folgt man der Argumentation, dass VR eine nat{\"u}rliche Interaktion mit virtuellen Objekten erm{\"o}glicht, so f{\"u}hrt dies fast zwangsl{\"a}ufig zu zweih{\"a}ndigen Interaktionstechniken f{\"u}r virtuelle Umgebungen, da Benutzer in realen Umgebungen gewohnt sind, fast ausschlie{\"i}‚lich zweih{\"a}ndig zu agieren.

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. In this paper, we discuss the problems we encountered while developing such a vibrotactile display. Keeping these pitfalls in mind could lead to better feedback systems for actors in virtual studio environments.}, language = {en} } @inproceedings{TiatorGeigerDewitzetal.2018, author = {Tiator, Marcel and Geiger, Christian and Dewitz, Bastian and Fischer, Ben and Gerhardt, Laurin and Nowottnik, David and Preu, Hendrik}, title = {Venga!: climbing in mixed reality}, series = {Proceedings of the First Superhuman Sports Design Challenge on First International Symposium on Amplifying Capabilities and Competing in Mixed Realities - SHS '18, Delft, 02.07.2018 - 05.07.2018}, booktitle = {Proceedings of the First Superhuman Sports Design Challenge on First International Symposium on Amplifying Capabilities and Competing in Mixed Realities - SHS '18, Delft, 02.07.2018 - 05.07.2018}, editor = {Lukosch, Stephan and Kunze, Kai}, publisher = {ACM Press}, address = {New York}, isbn = {9781450364072}, doi = {10.1145/3210299.3210308}, pages = {1 -- 8}, year = {2018}, language = {en} } @inproceedings{TiatorKerkmannGeigeretal.2020, author = {Tiator, Marcel and Kerkmann, Anna Maria and Geiger, Christian and Grimm, Paul}, title = {Using Semantic Segmentation to Assist the Creation of Interactive VR Applications}, series = {2020 IEEE International Conference on Artificial Intelligence and Virtual Reality (AIVR), Utrecht, 14.12.2020 - 18.12.2020}, booktitle = {2020 IEEE International Conference on Artificial Intelligence and Virtual Reality (AIVR), Utrecht, 14.12.2020 - 18.12.2020}, publisher = {IEEE}, isbn = {978-1-7281-7463-1}, doi = {10.1109/AIVR50618.2020.00011}, pages = {1 -- 9}, year = {2020}, language = {en} } @article{TiatorKerkmannGeigeretal.2021, author = {Tiator, Marcel and Kerkmann, Anna Maria and Geiger, Christian and Grimm, Paul}, title = {US2RO: Union of Superpoints to Recognize Objects}, series = {International Journal of Semantic Computing}, volume = {15}, journal = {International Journal of Semantic Computing}, number = {04}, publisher = {World Scientific Publishing}, issn = {1793-351X}, doi = {10.1142/S1793351X21400146}, pages = {513 -- 537}, year = {2021}, language = {en} } @inproceedings{LadwigPechDorneretal.2020, author = {Ladwig, Philipp and Pech, Alexander and Dorner, Ralf and Geiger, Christian}, title = {Unmasking Communication Partners: A Low-Cost AI Solution for Digitally Removing Head-Mounted Displays in VR-Based Telepresence}, series = {2020 IEEE International Conference on Artificial Intelligence and Virtual Reality (AIVR), Utrecht, 14.12.2020 - 18.12.2020}, booktitle = {2020 IEEE International Conference on Artificial Intelligence and Virtual Reality (AIVR), Utrecht, 14.12.2020 - 18.12.2020}, publisher = {IEEE}, isbn = {978-1-7281-7463-1}, doi = {10.1109/AIVR50618.2020.00025}, pages = {82 -- 90}, year = {2020}, language = {en} } @inproceedings{GeigerRattay2008, author = {Geiger, Christian and Rattay, Oliver}, title = {TubeMouse - A Two-Handed Input Device for Flexible Objects}, series = {2008 IEEE Symposium on 3D User Interfaces, 08.03.2008 - 09.03.2008, Reno}, booktitle = {2008 IEEE Symposium on 3D User Interfaces, 08.03.2008 - 09.03.2008, Reno}, publisher = {IEEE}, isbn = {978-1-4244-2047-6}, doi = {10.1109/3DUI.2008.4476587}, pages = {27 -- 34}, year = {2008}, language = {en} }
