We discuss the impact of Virtual Reality, Augmented Virtuality and Augmented Reality for specific memorial locations. We show how to use a virtual studio for demonstrating an augmented reality application for a specific location in a remote session within a video conference. Augmented Virtuality is used to recreate the local environment, thus providing a context and helping the participants recollect emotions related to a certain place. This technique demonstrates the advantages of using virtual (VR) and augmented (AR) reality environments for rapid prototyping and pitching project ideas in a live remote setting.}, language = {en} } @inproceedings{ZimmerBertramBuentigetal.2017, author = {Zimmer, Christian and Bertram, Michael and B{\"u}ntig, Fabian and Drochtert, Daniel and Geiger, Christian}, title = {Mobile augmented reality illustrations that entertain and inform with the hololens}, series = {SIGGRAPH Asia 2017 Mobile Graphics \& Interactive Applications on -

e.g. for navigational tasks. 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.

This paper explores past research, shows alternative approaches and proposes novel interaction tools for pending problems.
