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. Results from an initial pilot study indicate that vibrotactile feedback is a suitable non-visual aid for interaction that is at least comparable to audio-visual alternatives used in virtual set productions.}, language = {en} } @inproceedings{WoeldeckeMarinosPogschebaetal.2011, author = {W{\"o}ldecke, Bj{\"o}rn and Marinos, Dionysios and Pogscheba, Patrick and Geiger, Christian and Herder, Jens and Schwirten, Tobias}, title = {radarTHEREMIN - Creating Musical Expressions in a Virtual Studio Environment}, series = {2011 IEEE International Symposium on VR Innovation}, booktitle = {2011 IEEE International Symposium on VR Innovation}, publisher = {IEEE}, address = {Singapore}, isbn = {978-1-4577-0055-2}, doi = {10.1109/ISVRI.2011.5759671}, pages = {345 -- 346}, year = {2011}, abstract = {In this paper we describe a prototypical system for live musical performance in a virtual studio environment.

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.
