Physical Computing

In the x-med-k workshop physical computing, we will investigate connecting the physical world to the realm of the computer.
By using sensors and an inexpensive interface board, we can create a range of selfmade devices, from unheard of musical instruments to interactive installations.
Movement, gestures, airflow, touch, heat… can all be used to control sound and visuals.
The workshop has a distinct focus on an artistic exploration of the possibilities of physical computing. Partcipants will get to know the different kinds of sensors, how they are used and how to combine them with the computer to create artworks.

After my first interactive project at OpenLab in 2005, and the video realtime workshop given by imal this summer, I really wanted to learn more about sensors and their working. So, this workshop was a good starting point to play with this.
I had no skills in electronics and just a basic knowledge of max-msp which was already expired on my computer… I had to work with pure data which is less user friendly and to deal with electronic theory stuff which seems always very “abstract” when you are not in the practice. Well, the first day was hard but when we started to build our own sensor it was getting very fun, almost the soldering of very small resistors, diode and wire together…
In the end, we have built a multi-sensor box with the arduino breadboard inside and we add small applications (sound or visual) to the data’s captured in pure data. The first sensor we have built was a kind of « slider » detecting fingers position, the other was a piazzo on wich you can knock and the last one was a magnetic sensor.
As a conclusion I can say that I really liked the aspect of combining something practical with computing. This was a good starting point and I have discovered a complete new world. But I also realized that there is still a long road to go to develop the projects I like to do…

Real-time audio-visual systems and tools

‘Real-time audio-visual systems and tools’ (FoAM)
with Tom Schouten, David Griffiths, Tim Boykett, Steven Pickles, Nik Gaffney, Maja Kuzmanovic, Kate Rich, Goran Kuzmanovic
(and remote discussions with Adam Hyde regarding flossmanuals.net/)

Many forms of experimental media arts include generation and manipulation of real-time audio-visual media. Being able to generate compelling animations and sonic compositions in real-time is essential for media performances (including live-coding, VJing…), interactive installations, responsive situations, games etc. A lot of tools for making such works are proprietary, have problematic licensing and (for many people) a prohibiting cost. Hence, several artists are looking for viable alternatives. What are the challenges of developing and using artistic, open source tools, such as fluxus, packet forth, ogre and pd? Artists participating in this workshop are simultaneously building these tools and creating artworks with them, seamlessly morphing between developers and users. This free-form master class is designed to encourage discussions and experiments for a group of artists-developers, to find strengths and weaknesses of their approaches to procedural media.
