The tracking component of the system, radarTRACK, is based on a laser scanner device capable of delivering interaction points on a large configurable plane. By using the device on the floor it is possible to use the delivered data to detect feet positions and derive the position and orientation of one or more users in real time. The second component of the system, named OscCalibrator, allows for the easy creation of multidimensional linear mappings between input and output parameters and the routing of OSC messages within a single modular design environment.

We describe a tangible multitouch planning system, enabling multiple users to prepare and customize scene flow and settings. Users can collaboratively view and interact with virtual objects by using a tangible user interface on a shared multitouch surface. 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. Within the developing process, a video prototype of the system shows the user interaction and enables early reviews and evaluations. The requirement analysis is based on expert interviews.}, language = {en} } @inproceedings{KlapdohrWoeldeckeMarinosetal.2010, author = {Klapdohr, Monika and W{\"o}ldecke, Bj{\"o}rn and Marinos, Dionysios and Herder, Jens and Geiger, Christian and Vonolfen, Wolfgang}, title = {Vibrotactile Pitfalls: Arm Guidance for Moderators in Virtual TV Studios}, series = {HC '10 Proceedings of the 13th International Conference on Humans and Computers}, booktitle = {HC '10 Proceedings of the 13th International Conference on Humans and Computers}, publisher = {University of Aizu Press}, address = {Aizu-Wakamatsu}, pages = {72 -- 80}, year = {2010}, abstract = {For this study, an experimental vibrotactile feedback system was developed to help actors with the task of moving their arm to a certain place in a virtual tv studio under live conditions. 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{GeigerHerderGoebeletal.2010, author = {Geiger, Christian and Herder, Jens and G{\"o}bel, Sebastian and Heinze, Christin and Marinos, Dionysios}, title = {Design and Virtual Studio Presentation of a Traditional Archery Simulator}, series = {Proceedings of the Entertainment Interfaces Track 2010 at Interaktive Kulturen, Duisburg, Germany, September 12-15, 2010}, booktitle = {Proceedings of the Entertainment Interfaces Track 2010 at Interaktive Kulturen, Duisburg, Germany, September 12-15, 2010}, address = {Duisburg}, pages = {37 -- 44}, year = {2010}, abstract = {In this paper we describe the design of a virtual reality simulator for traditional intuitive archery. 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} }
