A metal bowl filled with water visualizes the human heartbeat through vibration and according patterns in the water surface. The title Herzfassen derives from the german expression for 'to take heart' thus hints to the haptic and emotional experience with the object. This paper describes aim and design of the piece, comprising construction, technical function, as well as the interaction cycle respectively the object's dramaturgy. Further, it reports on audience's joyful and emotional experiences with the object within past exhibitions as display and use hence human contact is the main purpose of Herzfassen.}, subject = {Design}, language = {en} } @inproceedings{BreuerDierichsElsholz, author = {Breuer, Henning and Dierichs, Tillmann and Elsholz, Stefanie}, title = {A comfort zone for mobile learning}, series = {Proceedins of the IADIS International Conference Mobile Learning 2012}, booktitle = {Proceedins of the IADIS International Conference Mobile Learning 2012}, publisher = {IADIS Press}, address = {Berlin}, organization = {International Association for Development of the Information Society (IADIS)}, isbn = {978-972-8939-66-3}, pages = {75 -- 82}, abstract = {Mobile learning activities of commuters have widely been neglected. The paper reports on the adaption of a grounded innovation approach involving a futures workshop for interaction design and ideation based on ethnographic insights in the field of mobile learning. Current obstacles and utopian futures of mobiles learning lay the grounds for envisioning new systems to support mobile learning for public transport. A system to enhance comfort zones for mobile learners is being specified and illustrated. It proposes a gesture-based handling of tablet computers in order create an adaptable and comfortable personal learning environment with individually adaptable and familiar modules. An iDesk prototype preserving a personal comfort zone for mobile learners is presented. The system intends to support formal and informal learning in mobile times.}, subject = {Lernen}, language = {en} } @inproceedings{MeierMatthiesUrbanetal., author = {Meier, Anita and Matthies, Denys J.

For this specific task, many researchers already provide different approaches such as vibrating belts, wristbands or shoes. Still, there are issues left that have to be considered, such as which body position is most suitable, what kind of vibration patterns are easy to interpret, and how applicable are vibrotactile feedback systems in real scenarios. To find answers, we reconstructed prototypes commonly found in literature and continued to further evaluate different foot-related designs. On the one hand, we learned that vibrotactile feedback at the foot reduces visual attention and thus also potentially reduces stress. However, on the other hand, we found that urban space can be very diverse, and ambiguous and therefore a vibrotactile system cannot completely replace common path finding systems for pedestrians. Rather, we envision such a system to be applied complementary as an assistive technology.}, subject = {Taktiler Sensor}, language = {en} } @inproceedings{ToglerHemmertWettach, author = {Togler, Jonas and Hemmert, Fabian and Wettach, Reto}, title = {Living interfaces}, series = {TEI '09 : Proceedings of the 3rd International Conference on Tangible and Embedded Interaction}, booktitle = {TEI '09 : Proceedings of the 3rd International Conference on Tangible and Embedded Interaction}, publisher = {Association for Computing Machinery}, address = {New York}, isbn = {978-1-60558-493-5}, doi = {10.1145/1517664.1517680}, pages = {43 -- 44}, abstract = {In this paper, we present a novel type of persuasive home appliance: A thrifty water faucet.

However, as these prototypes are generally constructed using solder-free technologies, they are often fragile and unreliable. This means a huge burden of care and upkeep for these inventions when they are either exhibited or sold. We present a software application called Fritzing which allows artists, designers and DIY-tinkerers to prepare their hardware inventions for production. Through an interface metaphor based on the typical workflow of the target group, Fritzing has proven its ability to provide useful support in the steps following the invention of an interactive artifact. Fritzing serves also as a tool for documenting these interactive artifacts. As sharing of knowledge has been a driving force within this new DIY-movement, there is a need for a consistent and readable form of documentation which Fritzing can provide. Fritzing has also proven to be a useful tool in teaching electronics to people without an engineering background.}, subject = {Design}, language = {en} } @inproceedings{NagelDuval, author = {Nagel, Till and Duval, Erik}, title = {Muse}, series = {Proceedings of the 2nd International Workshop on Research 2.0. : At the 5th European Conference on Technology Enhanced Learning: Sustaining TEL}, volume = {675}, booktitle = {Proceedings of the 2nd International Workshop on Research 2.0. : At the 5th European Conference on Technology Enhanced Learning: Sustaining TEL}, publisher = {RWTH}, address = {Aachen}, issn = {1613-0073}, pages = {48 -- 52}, abstract = {This paper introduces Muse, an interactive visualization of publications to explore the collaborations between institutions.
