Stick, Click n' Call
(2009)
This paper describes a new interaction concept, which is based on customizable self-adhesive stickers with an integrated button, manufacturable at low cost. By pressing the button, users can execute specialized functionalities on their mobile phones, e.g. dialing phone numbers or accessing URLs. We present three usage scenarios and a proof-of-concept prototype.
Fritzing
(2009)
Today a growing community of DIY-practitioners, artists and designers are using microcontroller-based toolkits to express their concepts for digital artifacts by building them. 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.
This studio will give participants a hands-on introduction to Fritzing, a free software tool for advancing electronic prototyping for researchers and practitioners of tangible, interactive electronics. Participants will bring one of their hand-wired prototypes (or a concrete concept) and in several steps learn to document it properly, share it with the community, and turn it into a professional printed circuit board.
Dynamic knobs
(2008)
In this paper, we introduce the change of a mobile phone's hardware shape as a means of tactile interaction.
The alteration of shape is implemented in a hardware prototype using a dynamic knob as an interaction device for the user. The knob alters the phone's shape according to different events and states, like incoming calls, new voice mail, or missed calls. Therefore, the user can explore the phone's status by touching it - ambiently, even through the pocket. Initial user testing showed that this form of tactile interaction was easy to understand and handy to interact with, also for unexperienced users.
Articulated paint
(2007)
In this paper we present the concept and prototype of a new musical interface that utilizes the close relationship between gestural expression in the act of painting and that of playing a musical instrument in order to provide non-musicians the opportunity to create musical expression. A physical brush on a canvas acts as the instrument. The characteristics of its stroke are intuitively mapped to a conductor program, defining expressive parameters of the tone in real-time. Two different interaction modes highlight the importance of bodily expression in making music as well as the value of a metaphorical visual representation.
