Flick Flock updates

During the exhibition of Flick Flock at Campus Party Brazil there was quite some interest expressed in the technologies we used to build Flick Flock, and how others can extend or customize Flick Flock to build their own installation or use it for their own personal projects.

What open source tools should we use?

The choice of software is important for a project with a limited production time. It is important to choose tools that can easily be integrated or implemented out of the box. Meaning, it important to consider the number of people in the community that are willing to support the development or implementation of the software (such that one will not build the software from scratch). We chose two main free and open source tools to help us build Flick Flock: Blender 3D for the graphical interface and Pure Data for the open computer vision software. In addition, to connect Blender 3D and Pure Data, we used Blendnik as an interface library.

Blender 3D was chosen not only because it is free but also because it’s such a great tool with a lot of functionality and plug-ins that didn’t require so much time to implement ourselves. It can easily implement high performance graphics such as OpenGL without cumbersome programming. Blender 3D also has the BGE (or Blender Game Engine) that we can easily interface with other software in real-time using python scripting.

With the Blendnik library, we were able to easily incorporate Open Sound Control (OSC) protocol to communicate among the technologies we used for the installation, such as computer vision, sound and the graphical interface. Blendnik uses object-oriented objects written in python to easily communicate with Blender. (more…)

Piksel09 in Bergen, Norway

Monday, November 23rd, 2009

I’ve just returned from Piksel09 in Bergen where BALTAN continued its great collaboration with Piksel. Many thanks to Gisle, Elisabeth and Hillevi from the Piksel team!

Friday, November 20 was the opening of the Piksel09 exhibition at Galleri 3,14 in Bergen, Norway, where Wendy Ann Mansilla and Jordi Puig, who have been working in residence at BALTAN Laboratories over the last month, debuted their new work Flick Flock. The work will be on view in the exhibition until January 10, 2010.

Saturday evening, Piksel09 also hosted a lively panel discussion with Wendy Ann, Jordi, Angela Plohman from BALTAN and Julien Ottavi (APO33) around open artistic production: blueprints, archiving and open source technology. In this Piksel Plenum panel, the audience was invited to participate in a lounge talk where we explored how processes of artistic production can be shared beyond pure archiving and documentation.

Wendy Ann Mansilla and Jordi Puig in residence at BALTAN

Thursday, October 15th, 2009

As part of BALTAN’s collaboration with Piksel in Norway, we put out an open call in the summer for proposals from artists who were specifically interested in working with the tracking and mapping technology Open Computer Vision. We received a number of high quality proposals through this call and in the end, Piksel and BALTAN selected the project Flick Flock by Wendy Ann Mansilla and Jordi Puig. Wendy Ann and Jordi participated in the OpenCV workshop that was held here in September and arrive next week to start their 4 week residency at BALTAN. The results of their work will be presented at the Piksel Festival in Bergen from November 19-22.

Flick Flock

Flick Flock defines the meaning of the body and its linkage to the continuous transformation of the urban place and the way it can construct and deconstruct society. It is reflecting the interconnections of bodies and space, reshaping each other to form such an unbound relationship. Using stereoscopic and ambisonic 3D technology, Flick Flock recreates the digital urban space we are living in to allow us to immersively experience the role of the physical body as a vehicle of expression and knowledge.

New version of OpenCV for PD, codename BALTANIK

Wednesday, October 14th, 2009

Report by Yves Degoyon, workshop leader (along with Lluis Gomez i Bigorda), OpenCV workshop at BALTAN Laboratories, September 21-27, 2009

After 2 years of playing around with computer vision in various contexts and installations, working mainly with performers and choregraphers, we were eager to share these experiments with other people interested in the subject and very interested to test our recently published library: ‘OpenCV for Pure Data’ in a wider context and with people involved in different kinds of applications using
computer vision.

This opportunity was given to us during the workshop organized by BALTAN Laboratories in Eindhoven, from the 21st to the 27th of September 2009. A variety of people showed up with different interests and needs and we tried to provide solutions for their projects using the toolbox we are developing, based on OpenCV.

Niko Knappe and Tara Pattenden (TAIK Media Lab, Helsinki) work in new media installations and were curious to learn new interaction techniques using a simple camera. After inspecting the different algorithms available, they opted for some interaction based on shape recognition and realized a first prototype of a ‘Fruit Detector’, working in the direction of making playful environments.

Great start to the OpenCV workshop

Wednesday, September 23rd, 2009

This week, in collaboration with Piksel, we are hosting an OpenCV workshop led by Lluis Gómez i Bigórda (Hangar.org, Barcelona) and Yves Degoyon (GISS.tv, Barcelona). We were really amazed by the extensive interest in this workshop, which has resulted in a great group of very diverse people coming to Eindhoven for the week. Niko Knappe and Tara Pattenden are studying at the TAIK Media Lab in Helsinki. Mateu Batle and Alberto de Rodrigo Aparacio are from the IBIT Foundation in Mallorca, Spain, working on telerehabilitation projects. Qi Wu works at Volkswagen in Germany. Artist Michael Aschauer dropped by on Monday. Wendy Ann Mansilla and Jordi Puig have come from Trondheim in Norway, where they both work at the NTNU. Francesco Bruno from Italy is working on developing a touchscreen device installed on machines for aerobics training in a gym. A dozen students from the TU/e Industrial Design department are also taking part. And Geert Mul and Erik Overmeire, both working on the BALTAN tracker project, are also here.

We’ll post more photos from the workshop later this week. You can also follow the content of the workshop on the workshop wiki, hosted by Piksel. Thanks to Gisle and Elisabeth from Piksel for their collaboration!
