After an extended time of inactivity there is finally a new reacTIVision 1.5 release available! While I initially only planned some minor updates in order to recompile on more recent systems, this eventually resulted in a major infrastructure update that primarily provides improved camera support and configuration options on all platforms as well as some internal tweaks that improve the overall performance. This includes a multi-threaded thresholder, an accelerated background subtractor as well as a quicker and less tedious calibration procedure. Apart from that this release does not yet include any changes to the core fiducial and finger tracking, which will be part of a future 1.6 release …
The source code and binaries for all supported platforms along with a comprehensive changelog are available on Github
Our Open Design Symposium will take place on Wednesday May 23rd 2012 at the Auditorium of the University of Art and Design in Linz, Austria. If you plan to attend this event, which will be held entirely in English language, please make sure to register for FREE on the symposium web site.

This symposium intends to discuss the Open Design practice from various perspectives, such as art, design, engineering, education, society and economy. An international selection of expert speakers will provide an insight into the state of the art and future directions of an emerging field, which holds countless opportunities for regional development and worldwide distribution based on the principles of collaboration and shared knowledge.
The Tworse Key is an Open Design exercise in interface archaeology that decodes the input from a classic telegraph key to send Twitter messages composed in Morse code.
Telegraphy is the short messaging service from the 19th century, the Morse code and the Telegraph as the according input device have become long obsolete since. Today instead we are using services such as SMS and Twitter for the delivery of our short messages, which are usually sent from mobile devices on every occasion in our daily lives. The idea to connect the antique interface of the Morse key with the contemporary Twitter service intends to reestablish an obsolete cultural technique within the current practice. The limited input possibilities of the Telegraph may also allow us to reflect upon the actual content of our messages, before broadcasting any arbitrary activity.
The design of the device loosely resembles the aesthetics of the 19th century, which is commonly referred as Steampunk in popular culture. The Tworse Key itself consists of an old brass telegraph, which basically just represents an ordinary switch mounted on a wooden box. This old technology is internally connected to a common Arduino Ethernet microcontroller board, which decodes the messages typed in Morse code and delivers them directly to the Twitter service through its built-net network connection. The Tworse Key is completely stand-alone and connects to any standard Ethernet network.
This project is fully documented in order to illustrate the Open Design process for beginners, who are aiming to study and realize a simple but yet appealing open artwork. The source code, hardware schematics and building instructions of this very elementary circuit are available under the according free licenses.
On October 22nd I had the opportunity to talk at the TEDxVienna conference, where I presented the basic concepts of Tangible Musical Interfaces that led us to the development of the Reactable. This included a brief introduction into the design history of acoustic and electronic musical instruments and the problem of controlling complex synthesizers with standard tools. Our solution employs the ideas of tangible interfaces in order to realize an instrument that combines physical interaction with auditory and visual feedback. The talk concludes with a brief description of the Reactable itself and our contribution to the design of tangible interactive surfaces.
During the conference we also had the opportunity to organize a small showcase, where in addition to the Reactable two works from our latest Interface Culture exhibition were presented. The exhibited works were FMR1 by Fabrizio Lamoncha, Ioan Cernei & Maša Jazbec as well as the GearBox by Ulrich Brandstätter & Oliver Buchtala
To be honest I have been an initial admirer of interactive media facades ever since I got aware of Blinkenlights and the Clickscape projects. During the last decade the topic has become mainstream though, leading to the construction of media facades in many “second cities” around the world aiming to catch up with the information age. There now even exists an European Media Facade Festival, dedicated to the production of actual artistic content for the usually commercially used large scale displays, but most of the proposals hardly exceed the aesthetics of screen savers and iTunes sound visualizations. Although the topic still seems to be extremely attractive amongst young media artists, it has become time to take action against the inflationary installation of urban screen savers!
Dead pixel art is a new form of digital reverse graffiti, which allows the appropriation of urban displays through the active disabling of selected pixels. For this purpose I am planning to employ a directed high-energy EMP (Electromagnetic Pulse) gun, which temporarily or permanently disrupts the electronic circuitry of an individual pixel element when pointing at it. This will allow the drawing of permanently visible black voids within any displayed animation, leading eventually to the complete destruction of the whole display.
A similar approach using different techniques can also be applied to CRT or LCD screens through the destruction of selected pixels, resulting in the permanent display of the applied dead pixel art. While this may be mostly interesting for information guerilla in a public screen context, such as ATM machines or info terminals, it can also be used for the personalization of individual devices.
The TuioPad is an open source TUIO tracker for iOS devices such as the iPad, iPhone and iPod touch, which allows multi-touch remote control based on the TUIO protocol. This application is available free of charge on the App Store and can be used in conjunction with any TUIO enabled client application. Its source code is also available under the terms of the GPL and therefore can be freely used for the creation of open source TUIO enabled mobile applications. Apart from that the TuioPad is also a useful tool for the development and testing of TUIO 1.1 client implementations.
I just released a proof-of-concept TUIO hand gesture tracker for the popular Microsoft Kinect controller. This allows the rapid creation of gesture enabled applications with any platform or environment that supports the TUIO protocol. The application still needs several improvements to become fully usable. Nevertheless it should work out of the box with most TUIO client applications. Most of the code is based on OpenFrameworks and its ofxKinect example, which is integrating libfreenect by the OpenKinect project.
You can download the application source code and a binary for Mac OS X 10.6 (Intel) from its Google code project page. Any suggestions for improvements or specific features are welcome!
The Interface Culture Lab at the University of Art and Industrial Design in Linz/Austria provides an internationally oriented master program in Interactive Media Arts. The two-year program, which is entirely organized in English language, is open to prospective students with multidisciplinary backgrounds integrating art, design, science and technology.
We are currently accepting new students for the master class of the upcoming academic year 2010/11 and would therefore like to point you to the online registration form, which will be open until June 18th 2010. The application interviews will take place in Linz on June 30th or alternatively on September 7th during the Ars Electronica Festival.
Next week this year’s edition of the LiWoLi 2010 will again take place at the University of Arts and Industrial Design in Linz. From April 15-17 there will be several talks, discussions and workshops around open source communities and technologies in the context of artistic production and teaching practice. I will also hold a TUIO workshop on Open Tools for Tangible Interaction, there are still a few places left if you are interested in that topic and happen to be around in Linz that time. There are several more workshops held by key developers of Pure Data and Open Frameworks for example, and the rest of the activities around the general practice of open source within artistic communities is also quite promising.
