Workshop Virtuelle und Erweiterte Realit{\"a}t der GI-Fachgruppe VR/AR}, address = {Wedel}, year = {2011}, abstract = {This paper presents a tracking of parts of a human body in a virtual TV studio environment. The tracking is based on a depth camera and a HD studio camera and aims at a realistic interaction between the actor and the computer generated environment. Stereo calibration methods are used to match corresponding pixels of both cameras (HD color and depth image). Hence the images were rectified and column aligned. The disparity is used to correct the depth image pixel by pixel. This image registration results in row and column aligned images where ghost regions are in the depth image resulting from occlusion. Both images are used to generate foreground masks with chroma and depth keying. The color image is taken for skin color segmentation to determine and distinguish the actor's hands and face. In the depth image the flesh colored regions were used to determine their spatial position. The extracted positions were augmented by virtual objects. The scene is rendered correctly with virtual camera parameters which were calculated from the camera calibration parameters. Generated computer graphics with alpha value are combined with the HD color images. This compositing shows interaction with augmented objects for verification. The additional depth information results in changing the size of objects next to the hands when the actor moves around.}, language = {en} } @inproceedings{MayerPogschebaMarinosetal.2014, author = {Mayer, Christian and Pogscheba, Patrick and Marinos, Dionysios and W{\"o}ldecke, Bj{\"o}rn and Geiger, Christian}, title = {An audio-visual music installation with dichotomous user interactions}, series = {Proceedings of the 11th Conference on Advances in Computer Entertainment Technology, Funchal, 11.11.2014-14.11.2014}, booktitle = {Proceedings of the 11th Conference on Advances in Computer Entertainment Technology, Funchal, 11.11.2014-14.11.2014}, editor = {Chisik, Yoram and Geiger, Christian and Hasegawa, Shoichi}, publisher = {ACM}, address = {New York}, isbn = {9781450329453}, doi = {10.1145/2663806.2663842}, pages = {1 -- 6}, year = {2014}, language = {en} } @inproceedings{StoeckleinPogschebaGeigeretal.2010, author = {St{\"o}cklein, J{\"o}rg and Pogscheba, Patrick and Geiger, Christian and Paelke, Volker}, title = {MiReAS: a mixed reality software framework for iterative prototyping of control strategies for an indoor airship}, series = {Proceedings of the 7th International Conference on Computer Graphics, Virtual Reality, Visualisation and Interaction in Africa - AFRIGRAPH '10 , 21.06.2010 - 23.06.2010, Franschhoek}, booktitle = {Proceedings of the 7th International Conference on Computer Graphics, Virtual Reality, Visualisation and Interaction in Africa - AFRIGRAPH '10 , 21.06.2010 - 23.06.2010, Franschhoek}, editor = {Gain, James and Marais, Patrick}, publisher = {ACM Press}, address = {New York}, isbn = {9781450301183}, doi = {10.1145/1811158.1811164}, pages = {27}, year = {2010}, language = {en} } @inproceedings{StoeckleinGeigerPaelkeetal.2009, author = {St{\"o}cklein, J{\"o}rg and Geiger, Christian and Paelke, Volker and Pogscheba, Patrick}, title = {A Design Method for Next Generation User Interfaces Inspired by the Mixed Reality Continuum}, series = {Virtual and Mixed Reality, Third International Conference, VMR 2009, Held as Part of HCI International 2009, San Diego, CA USA, July, 19-24, 2009, Proceedings}, booktitle = {Virtual and Mixed Reality, Third International Conference, VMR 2009, Held as Part of HCI International 2009, San Diego, CA USA, July, 19-24, 2009, Proceedings}, editor = {Shumaker, Randall}, publisher = {Springer}, address = {Berlin, Heidelberg}, isbn = {978-3-642-02770-3}, doi = {10.1007/978-3-642-02771-0_28}, pages = {244 -- 253}, year = {2009}, language = {en} } @inproceedings{StockleinGeigerPaelkeetal.2009, author = {Stocklein, Jorg and Geiger, Christian and Paelke, Volker and Pogscheba, Patrick}, title = {Poster: MVCE - a design pattern to guide the development of next generation user interfaces}, series = {2009 IEEE Symposium on 3D User Interfaces, 14.03.2009 - 15.03.2009, Lafayette}, booktitle = {2009 IEEE Symposium on 3D User Interfaces, 14.03.2009 - 15.03.2009, Lafayette}, publisher = {IEEE}, isbn = {978-1-4244-3965-2}, doi = {10.1109/3DUI.2009.4811232}, pages = {153 -- 154}, year = {2009}, 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.

It is our belief that context awareness has the potential to supplement the Internet of Things, when a suitable methodology including supporting tools will ease the development of context-aware applications. We believe that a meta-model based approach can be key to achieving this goal. In this paper, we present our meta-model based methodology, which allows us to define and build application-specific context models and the integration of sensor data without any programming. We describe how that methodology is applied with the implementation of a relatively simple context-aware COVID-safe navigation app. The outcome showed that programmers with no experience in context-awareness were able to understand the concepts easily and were able to effectively use it after receiving a short training. Therefore, context-awareness is able to be implemented within a short amount of time. We conclude that this can also be the case for the development of other context-aware applications, which have the same context-awareness characteristics. We have also identified further optimization potential, which we will discuss at the conclusion of this article.}, language = {en} } @article{KernebeckHollePogschebaetal.2019, author = {Kernebeck, Sven and Holle, Daniela and Pogscheba, Patrick and Jordan, Felix and Mertl, Fabian and Huldtgren, Alina and Bader, Sebastian and Kirste, Thomas and Teipel, Stefan and Holle, Bernhard and Halek, Margareta}, title = {A Tablet App- and Sensor-Based Assistive Technology Intervention for Informal Caregivers to Manage the Challenging Behavior of People With Dementia (the insideDEM Study): Protocol for a Feasibility Study}, series = {JMIR research protocols}, volume = {8}, journal = {JMIR research protocols}, number = {2}, publisher = {JMIR}, doi = {10.2196/11630}, year = {2019}, language = {en} }
