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} } @inproceedings{LadwigHerderGeiger2017, author = {Ladwig, Philipp and Herder, Jens and Geiger, Christian}, title = {Towards Precise, Fast and Comfortable Immersive Polygon Mesh Modelling: Capitalising the Results of Past Research and Analysing the Needs of Professionals}, series = {ICAT-EGVE 2017 - International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments}, booktitle = {ICAT-EGVE 2017 - International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments}, publisher = {The Eurographics Association}, doi = {10.2312/egve.20171360}, pages = {22 -- 24}, year = {2017}, abstract = {More than three decades of ongoing research in immersive modelling has revealed many advantages of creating objects in virtual environments. Even though there are many benefits, the potential of immersive modelling has only been partly exploited due to unresolved problems such as ergonomic problems, numerous challenges with user interaction and the inability to perform exact, fast and progressive refinements. This paper explores past research, shows alternative approaches and proposes novel interaction tools for pending problems. An immersive modelling application for polygon meshes is created from scratch and tested by professional users of desktop modelling tools, such as Autodesk Maya, in order to assess the efficiency, comfort and speed of the proposed application with direct comparison to professional desktop modelling tools.}, language = {en} } @inproceedings{HerderTakedaVermeegenetal.2019, author = {Herder, Jens and Takeda, Shinpei and Vermeegen, Kai and Davin, Till and Berners, Dominique and Ryskeldiev, Bektur and Zimmer, Christian and Druzetic, Ivana and Geiger, Christian}, title = {Mixed Reality Art Experiments - Immersive Access to Collective Memories}, series = {ISEA2019, Proceedings, 25th International Symposium on Electronic Art, Gwangju, South Korea, June 22-28, 2019}, booktitle = {ISEA2019, Proceedings, 25th International Symposium on Electronic Art, Gwangju, South Korea, June 22-28, 2019}, publisher = {IESA}, address = {Gwangju}, pages = {334 -- 341}, year = {2019}, abstract = {We report about several experiments on applying mixed reality technology in the context of accessing collective memories from atomic bombs, Holocaust and Second World War.

Augmented Virtuality is used to recreate the local environment, thus providing a context and helping the participants recollect emotions related to a certain place.
