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} } @inproceedings{GeigerFritzeLehmannetal.2008, author = {Geiger, Christian and Fritze, Robin and Lehmann, Anke and St{\"o}cklein, J{\"o}rg}, title = {HYUI: a visual framework for prototyping hybrid user interfaces}, series = {Proceedings of the 2nd international conference on Tangible and embedded interaction - TEI '08, 18.02.2008 - 20.02.2008, Bonn}, booktitle = {Proceedings of the 2nd international conference on Tangible and embedded interaction - TEI '08, 18.02.2008 - 20.02.2008, Bonn}, editor = {Schmidt, Albrecht and Gellersen, Hans and van den Hoven, Elise and Mazalek, Ali and Holleis, Paul and Villar, Nicolas}, publisher = {ACM Press}, address = {New York}, isbn = {9781605580043}, doi = {10.1145/1347390.1347406}, pages = {63}, year = {2008}, 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.

Thus, we have extended the AR/VR framework \sc Morgan with spatial audio to improve users orientation in an AR application. In this paper, we investigate the users' capability to localize and memorize spatial sounds (registered with virtual or real objects). We discuss two scenarios. In the first scenario, the user localizes only sound sources and in the second scenario the user memorizes the location of audio-visual objects.

This gas emission severely affects local population and has become a concern also for air traffic. The eruption has in December continued at constant pace for 3.5 months. Three scenarios are envisaged for the future; (1) the eruption stops, (2) the fissure extends under the Vattnaj{\"o}kul glacier and (3) Bardarbunga volcano erupts. The two later scenarios will cause increased gas emission, severe ash emissions and extended flooding. Under the scope of the EU-project FUTUREVOLC, a project with 3.5 years duration, aiming at making Iceland a supersite for volcanological research as a European contribution to GEO, we are developing a version of the Scanning DOAS instrument that is adapted to high latitudes with low UV radiation and severe meteorological conditions. Since the first day of the eruption several of these novel instruments has been monitoring the SO2 emission from the eruption. Data from our instruments are still after 3.5 months the only sustained ground-based monitoring of this gas emission. A lot of work is however needed to sustain this operation at a very remote site and under severe field conditions. At the same time the very high concentrations in the gas plume, in combination with bad meteorological conditions require the development of novel methods to derive reliable flux estimates. In this presentation we will discuss the instrumental issues and present the latest version of the emission estimates made from our measurements.}, subject = {Vulkanismus}, language = {en} } @article{GalbanMaderwaldHerrmannetal.2005, author = {Galban, Craig and Maderwald, Stefan and Herrmann, Burkhard and Brauck, K. and Grote, Wolfgang and de Greiff, A. and Uffmann, K. and Ladd, M.}, title = {Measuring Skeletal Muscle Elasticity in Patients with Hypogonadism by MR Elastography}, series = {Proc.
