It can be stressful to keep all the measured values under control when pursuing this ambitious way of life. Body weight can be an especially emotional issue for many people and slight differences can be perceived as lack of discipline, although little fluctuations are natural. In this paper, we present a tangible display for body weight, based on floor rigidity. It displays body weight without numbers, which makes it less suitable for comparisons, while still giving the user an idea about their weight. We describe the metaphorical foundations of the concept, as well as the development of two prototypes, which implement the envisioned full-body weighing experience. We demonstrate how the design of a display can influence the users' connotation of data.}, subject = {Haptische Feedback-Technologie}, 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{LoeweYoshaKrauseetal., author = {L{\"o}we, Matthias and Yosha, Omer and Krause, Alexander and Wettach, Reto and Kr{\"u}ger, Nils}, title = {Valeo}, series = {TEI '10 : Proceedings of the fourth international conference on Tangible, embedded, and embodied interaction}, booktitle = {TEI '10 : Proceedings of the fourth international conference on Tangible, embedded, and embodied interaction}, publisher = {Association for Computing Machinery}, address = {New York}, isbn = {978-1-60558-841-4}, doi = {10.1145/1709886.1709925}, pages = {213 -- 216}, abstract = {In current healthcare research, pain logs are an important means to measure the impact of medication and to detect pain patterns.

This paper introduces valeo, a new form of a tactile pain log, which is based on a vibrotactile, pressure- and tilt-sensitive device. Future iterations will also include body part recognition. By squeezing it close to one's own body, the subjective intensity of a local pain is manifested in the device. Via a shove gesture, it is then transmitted to a docking station. Advantageously, the pain data is covert and conceptually alienated from the patient's body, which may support a possible relief.
