Numerous models have been proposed in human-computer interaction (HCI) to guide research and analyze effects. However, bridging the gap between experimental data and real-world applications often proves to be difficult. In the last decades, post-cognitivistic approaches have been developed to explain human cognition and the relation between humans and their environment. In this paper, we present a novel framework to systematically describe and analyze challenges in the context of HCI from multiple perspectives. It extends Cultural-Historical Activity Theory (CHAT) and is enriched by contemporary philosophical perspectives (enactivism, pattern theory of self and post-phenomenology). The proposed framework is further illustrated by applying it to an immersive telementoring prototype system.}, subject = {Mensch-Maschine-Kommunikation}, language = {en} } @inproceedings{DewitzWicheGeigeretal.2018, author = {Dewitz, Bastian and Wiche, Roman and Geiger, Christian and Steinicke, Frank and Feitsch, Jochen}, title = {AR Sound Sandbox: A Playful Interface for Musical and Artistic Expression}, series = {Intelligent Technologies for Interactive Entertainment. 9th International Conference, INTETAIN 2017, Funchal, Portugal, June 20-22, 2017, Proceedings}, booktitle = {Intelligent Technologies for Interactive Entertainment. 9th International Conference, INTETAIN 2017, Funchal, Portugal, June 20-22, 2017, Proceedings}, editor = {Chisik, Yoram and Holopainen, Jussi and Khaled, Rilla and Luis Silva, Jos{\´e} and Alexandra Silva, Paula}, publisher = {Springer International Publishing}, address = {Cham}, isbn = {978-3-319-73061-5}, doi = {10.1007/978-3-319-73062-2_5}, pages = {59 -- 76}, year = {2018}, language = {en} } @inproceedings{DrochtertGeiger2015, author = {Drochtert, Daniel and Geiger, Christian}, title = {Collaborative magic lens graph exploration}, series = {SIGGRAPH Asia 2015 Mobile Graphics and Interactive Applications, Kobe, 02.11.2015-06.11.2015}, booktitle = {SIGGRAPH Asia 2015 Mobile Graphics and Interactive Applications, Kobe, 02.11.2015-06.11.2015}, publisher = {ACM}, address = {New York}, isbn = {9781450339285}, doi = {10.1145/2818427.2818465}, pages = {1 -- 3}, year = {2015}, language = {en} } @inproceedings{DrochtertGeigerHogenetal.2015, author = {Drochtert, Daniel and Geiger, Christian and Hogen, M. and Huldtgren, Alina and K{\"o}se, O. and Wiche, R. and Loss, L.}, title = {Public Brewing: a Media Fa{\c{c}}ade with a Mixed Reality Interface}, series = {Proceedings of the 4th International Symposium on Pervasive Displays, 10.06.2015-12.06.2015, Saarbr{\"u}cken}, booktitle = {Proceedings of the 4th International Symposium on Pervasive Displays, 10.06.2015-12.06.2015, Saarbr{\"u}cken}, editor = {Gehring, Sven and Kr{\"u}ger, Antonio and Alt, Florian and Taylor, Nick}, publisher = {ACM}, address = {New York}, isbn = {9781450336086}, doi = {10.1145/2757710.2757736}, pages = {69 -- 75}, year = {2015}, language = {en} } @inproceedings{DrochtertOwetschkinMeyeretal.2013, author = {Drochtert, Daniel and Owetschkin, Konstantin and Meyer, Laurid and Geiger, Christian}, title = {Demonstration of mobile virtual archery}, series = {SIGGRAPH Asia 2013 Symposium on Mobile Graphics and Interactive Applications on -

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{GeigerHogenHornigetal.2013, author = {Geiger, Christian and Hogen, Michael and Hornig, J{\"o}rn and Schaar, Michael}, title = {Datenreise: : digital bits made tangible}, series = {Proceedings of the 8th International Conference on Tangible, Embedded and Embodied Interaction - TEI '14, 16.02.2014 - 19.02.2014, Munich}, booktitle = {Proceedings of the 8th International Conference on Tangible, Embedded and Embodied Interaction - TEI '14, 16.02.2014 - 19.02.2014, Munich}, editor = {Butz, Andreas and Greenberg, Saul and Bakker, Saskia and Loke, Lian and de Luca, Alexander}, publisher = {ACM Press}, address = {New York}, isbn = {9781450326353}, doi = {10.1145/2540930.2540945}, pages = {283 -- 284}, year = {2013}, language = {en} }
