The system uses a wall-sized display that is seamlessly integrated into a living lab, to create a 'life-like' video communication experience. In order to demonstrate the potential of this approach, we conducted a living lab study comparing the developed prototype with a desktop-based system. A special video communication application, which enables spatially separated users to have a joint dinner experience, served as a common basis for the different test conditions. Results of the study show that the overall concept of roomXT was well eceived by users of a wide age range and that the developed prototype system seems to be preferred to commercially available video communication solutions with respect to the tested quality dimensions.}}, author = {{Kasugai, Kai and Heidrich, Felix and Röcker, Carsten and Russell, Peter and Ziefle, Martina}}, booktitle = {{Proceedings of the 2012 International Symposium on Pervasive Displays}}, editor = {{José, Rui}}, isbn = {{978-145-031-414-5 }}, keywords = {{human-computer interaction, mixed-reality, large displays, co-dining, interactive media, family communication, co-presence, architecture}}, location = {{Porto, Portugal }}, pages = {{1--6}}, publisher = {{ACM}}, title = {{{Perspective Views in Video Communication Systems: An Analysis of Fundamental User Requirements}}}, doi = {{10.1145/2307798.2307811}}, year = {{2012}}, } @inproceedings{2113, abstract = {{In this paper, we sketch an idea for the integration of singleclass support vector machines (SVM) into fuzzy class learning.
