Inventors workshop on printed electronics for tangible interaction

February 20-21, 2015 · Saarbrücken, Germany


The 7th inventors workshop of GI-Fachgruppe “Begreifbare Interaktion” (German Informatics Society Workgroup on Tangible Interaction) will be held on February 20-21, 2015 in Saarbrücken, Germany.

This year’s inventors workshop will focus on printed electronics for tangible interaction. Printed electronics is a powerful enabling technology for customized, thin, and deformable sensors and displays. It enables new kinds of physical objects and surfaces, in which interactivity is seamlessly integrated within the material and the form factor. As printed sensors and displays are highly customizable and can be rapidly fabricated, this is an ideal highly promising technology for making and prototyping. More information on this new approach can be found here, here and here.

This hands-on workshop will familiarize participants with current trends for printed electronics in Human-Computer Interaction. In practical sessions, participants will develop concepts for new tangible interfaces and then realize them using conductive inkjet printing and Arduino-based processing. For instance, teams can realize customized touch-sensitive tangibles, interactive paper applications, or wearable interfaces.

We are delighted to announce Wendy Mackay (INRIA and University Paris Sud) as the keynote speaker.

Franco-German event
The inventor workshop is part of the activities of the Tangible Interaction workgroup within the German Informatics Society.

We are opening up this workshop series and are cordially inviting members of the French tangible interaction community to participate in the workshop. Saarbrücken is located right at the German-French border, in a bilingual region, and therefore the ideal location for a Franco-German event.

Participation & Registration

We welcome participants with backgrounds in Computer Science, EE, Media, Design, Arts, Psychology or Cognitive Science. No prior knowledge in printed electronics, hardware, or microcontrollers is required (but will be helpful). Knowledge about tangible interaction will be helpful. We will balance groups, such that both novices and people with experience in physical computing will benefit from the workshop.

To participate, please register using the following form until January 23, 2015. We recommend to register early, as the number of places is limited due to the practical work.

Participation is free of charge. We thank the Cluster of Excellence on Multimodal Computing and Interaction for generous support.

Interactive Paper: A Whirlwind Tour of Tangible Computing from the Digital Desk to Music Composition

Interactive paper is a form of tangible computing that allows people to take full advantage of their existing cognitive and physical skills, and encourages us, as designers, to explore novel strategies for supporting creativity. This talk traces my own history with interactive paper, based on participatory design projects with creative professionals who successfully combine paper and computers. I begin with Pierre Wellner’s ground-breaking Digital Desk in the 1990’s and continue through to Phillippe LeRoux’s Quid Sit Musicus in 2014, which used interactive paper both during composition and as an integral part of the live performance. The insights we gained from these projects has led to a new way of thinking about interaction design. Our concept of co-adaptive instruments is based on instrumental Interaction, which treats interaction as a first class object and co-adaptation, which helps users both learn (adapt to) and appropriate (adapt) interactive systems. By taking cues from how people interact in the physical world, we can create less brittle systems that are easier to learn and appropriate, and support a wide variety of creative activities.

The workshop will be held in English.


The workshop will be held in the Embodied Interaction Lab and close-by rooms, located in building E 1.7 (Cluster of Excellence MMCI) on the campus of Saarland University.

Saarland University
Campus E1.7
66123 Saarbrücken

General directions to the university campus are available here:

Building E 1.7 is located north-east on the university campus, close to the bus stop “Universität Mensa”.

When arriving at the bus stop “Universität Mensa” coming from the city, you will find the MMCI building Campus E 1.7 right across the street.


When arriving at the bus stop “Universität Mensa” coming from the other direction (St. Ingbert, Dudweiler), walk downhill until you find the building on your left side.
