Consequently such feedback devices are used to guide blind or visually impaired people but can also be used to support other wayfinding tasks - for instance, guiding actors in virtual studio productions. Recent effort has been made to simplify this task by integrating vibrotactile feedback into virtual studio applications. In this work we evaluate the accuracy of an improved direction signalization technique, utilizing a body-worn vibrotactile belt with a limited number of tactors, and compare it to other work. The results from our user study indicate that it is possible to signalize different directions accurately, even with a small number of tactors spaced by 90°.}, language = {en} } @incollection{HerderGeigerLehmannetal.2009, author = {Herder, Jens and Geiger, Christian and Lehmann, Anke and Vierjahn, Tom and W{\"o}ldecke, Bj{\"o}rn}, title = {Designstrategien f{\"u}r den Einsatz von vibrotaktielem Feedback in Mixed Reality Anwendungen}, series = {Augmented \& Virtual Reality in der Produktentstehung}, volume = {232}, booktitle = {Augmented \& Virtual Reality in der Produktentstehung}, editor = {Gausemeier, J{\"u}rgen and Grafe, Michael}, publisher = {Heinz Nixdorf Institut, Universit{\"a}t Paderborn}, address = {Paderborn}, isbn = {978-3-939350-71-2}, pages = {225 -- 240}, year = {2009}, language = {de} } @inproceedings{MayerPogschebaMarinosetal.2014, author = {Mayer, Christian and Pogscheba, Patrick and Marinos, Dionysios and W{\"o}ldecke, Bj{\"o}rn and Geiger, Christian}, title = {An audio-visual music installation with dichotomous user interactions}, series = {Proceedings of the 11th Conference on Advances in Computer Entertainment Technology, Funchal, 11.11.2014-14.11.2014}, booktitle = {Proceedings of the 11th Conference on Advances in Computer Entertainment Technology, Funchal, 11.11.2014-14.11.2014}, editor = {Chisik, Yoram and Geiger, Christian and Hasegawa, Shoichi}, publisher = {ACM}, address = {New York}, isbn = {9781450329453}, doi = {10.1145/2663806.2663842}, pages = {1 -- 6}, year = {2014}, language = {en} } @inproceedings{WoeldeckeMarinosGeiger2014, author = {W{\"o}ldecke, Bj{\"o}rn and Marinos, Dionysios and Geiger, Christian}, title = {Flexible Registration of Multiple Displays}, series = {Proceedings of The International Symposium on Pervasive Displays, Copenhagen, 03.06.2014-04.06.2014}, booktitle = {Proceedings of The International Symposium on Pervasive Displays, Copenhagen, 03.06.2014-04.06.2014}, editor = {Gehring, Sven and Boring, Sebastian and Quigley, Aaron}, publisher = {ACM}, address = {New York}, isbn = {9781450329521}, doi = {10.1145/2611009.2611030}, pages = {86 -- 91}, year = {2014}, language = {en} } @inproceedings{MarinosWoeldeckeGeigeretal.2011, author = {Marinos, Dionysios and W{\"o}ldecke, Bj{\"o}rn and Geiger, Christian and Schwirten, Tobias}, title = {Design of a touchless multipoint musical interface in a virtual studio environment}, series = {Proceedings of the 8th International Conference on Advances in Computer Entertainment Technology -

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{WoeldeckeVierjahnFlaskoetal.2009, author = {W{\"o}ldecke, Bj{\"o}rn and Vierjahn, Tom and Flasko, Matthias and Herder, Jens and Geiger, Christian}, title = {Steering actors through a virtual set employing vibro-tactile feedback}, series = {TEI '09 Proceedings of the 3rd International Conference on Tangible and Embedded Interaction}, booktitle = {TEI '09 Proceedings of the 3rd International Conference on Tangible and Embedded Interaction}, publisher = {ACM}, address = {New York}, isbn = {978-1-60558-493-5}, doi = {10.1145/1517664.1517703}, pages = {169 -- 174}, year = {2009}, abstract = {Actors in virtual studio productions are faced with the challenge that they have to interact with invisible virtual objects because these elements are rendered separately and combined with the real image later in the production process. 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.

The in a 2D setting created TV scenes are simultaneously rendered on an external monitor, using a production/target renderer in 3D. Thereby the user experiences a closer reproduction of a final production. Subsequently, users are able to join together the scenes into one complex plot.
