Re: HELLERAU WORKSHOP 2.0

folks:

you've probably seen Robert Wechsler's draft of a description of the
on-going "Koerper - Computer - Interaktion" workshop at the
Festspielhaus Hellerau (Dresden, East Germany), organised by the
Medienkulturzentrum Dresden (July 20 - August 3). Final
presentations/performances are on Wednesday night, August 2, 9:oo pm,
Festspielhaus.
Everybody welcome!

Since the description breaks off in mid-air, I thought I'd add some
notes, mostly personal observations, since it is too soon to start
evaluating the conceptual process and the content of the laboratory
tests undertaken by the group.

WORKSHOP STRUCTURE:

Process directed by Palindrome dance company leaders Robert Wechsler
(choreogr.) and Frieder Weiss (computer engineer). Local organiser:
Joerg Sonntag (video/music artist, Medienkulturzentrum: 
http://www.body-bytes.de)

Co-directors: Guenter Haffelder, director of
the Instutute for Communication and Brain Research (Stuttgart), with
Christine Braun. 

Participants: 12,  including Dutch stage designer/media artist Rene
Verouden, and Spanish dancer/choreographer Angel Blasco, composer
Hartmut Dorschner, visual artist Holger Herrmann, and several young
dancers, musicians, videographers from Germany. 

1. We work physically in the morning, after shared breakfast
(everyone sleeps at Hellerau in the old arts-colony dormitories), we
have access to the big arena theatre, a dance studio, and 3 rooms which
we turned into the brain research center/video editing and music lab.

After warm ups we design and test interactive spaces in our dance
studio, with the Palindrome-developed software "EyeCon", which allows
the drawing of invisible "touchlines" or "dynamic fields" in the space
(monitored by cameras) in which we perform.

We explore the sensitivity of the space and our movements in the
interactive field, dynamic qualities, compositional potentials for the
live spatial interaction with sound (tones, music-samples, voice-texts)
or video (quicktime movie samples, etc), programmed so that movement in
space, even the slightest motion (of a
finger, an eyebrow) is registered and instantly triggers, via
Midi, a sound or soundtextures.


2. Now comes the challenging part, work we do in the
afternoons/evenings. Prof. Haffelder is a brain psychologist who has
developed a measuring/analytical system for brain waves (with
electroencephalograms and spectral analysis, meaning brainwaves are
measured via electrodes, and the computer translates the waves and
frequencies and creates visual graphic representations of the activity
in the left and right hemispheres (measured near the back, behind the
ears, nearer the deeper layers of brainwave activity, the limbian system
- allowing better access to synapse transmissions of emotional states
inside the brain/nervous system)

Haffelder works in the field of learning optimisation (disability,
blockades, trauma related accidents, etc), especially for children who
have trouble learning/concentating, etc., but also with
professional athletes and managers. His Institute has created a program
that allows them to tap into the brain to understand/alleviate synapse
problems, alleviate blockages, improve the bridge between the left and
right hemispheres, stimulating low frequencies or blocked
neurotransmissions thus enabling children and patients to learn better
by using specially produced music-CDs, for particular clients, so that
these clients listen to (Mozart) music that has been manipiulated and
altered according to the frequencies and signal responses that the brain
analysis suggests after the lab tests. The CDs can also help to improve
motor skills and coordination in damaged neural systems (after
accidents).

3.   I had my spectral analysis done on Sunday, and the test (70
minutes) was fascinating, I had electrodes on my head, closed my eyes
and went through the test (general questions, mathematical tasks,
raection tasks, personal questions); then they showed me my
brainwaves-diagrams on the computer. You can also see close-ups of areas
(measured in hz, graphically laid out/mapped in time sequences as
recorded, the so-called chronospectrogram). My Theta, and even Delta
values in the right hemisphere (parallel processing) apparently are
good, they concern the deeper visualising/meditative regions, near
dreams, deep/unconscious emotions, creativity, sensibility. On the left
side (serial processing: the logical,rational and speech side), I
sometimes show strange patterns, flatlands, so called
"Todstell-reflexe"  (simulated dead reflex), you know, like when an
animal feels it is trapped and pretends to be dead. I don't know what it
means.

4. The next day I was allowed to do a session with the EEG that was
unsual; I was hooked up to a second computer as well, and a program
translated my brainwave frequencies (which are of course electrical and
hz octave patterns similar to music/acoustic waves)  into notes, thus I
was listening to my brain making music. When I tried to
concentrate and visualize pleasant or deeply arousing images, my music
changed and became less melodic, because of the excitation; in relaxed
state my waves sound quite harmonious. 


II. OBJECTIVES
You will have guessed the artistic objective of our workshop.

Frieder, our computer programmer, is working on writing software code
that can link the electroencephalogram and its signals via midi directly
to the dance interactive program that we already have set up in the
dance studio, so that our brainwaves potentially can stimulate and
trigger sound and video images on stage during the performance (which is
something Haffelder is very interested in for his research in measuring
and evaulating creative energies and potentials/implications for the
neural system).

Furthermore, Frieder suggested that when we do our final public
performance at the end of the workshop, we invite a volunteer from the
audience to sit in front of the stage, between viewers and performers,
and be hooked to the EEG, react to the movement and
the stories/images/sounds, and immediately, via interface between
stage and audience-volunteer, we would potentially have an interface
that allows us to measure the brain response (emotional) activity of the
audience member, as well as allow for what is called "bio feedback": the
way the person is "touched" or identifies with
the movement, the way he or she also can re-stimulate the sounds and
images (video projecions) we experience in the performance as they are
triggered directly by the biofeedback-interface. The
reactions will show us something about how the audience emotionally
responds to a particular movement or sound.


It is planned that the group, together and in smaller collaborations
between members, develops 8 or 10 short interactive performances or
installations for presentation on August 2. 

The workshop thus has a scientific side and a cross-over artistic side,
and we are of course interested in investigating the meaning of
interactivity and the artistic and emotional potentials of performing in
interactive and in/with "nervous systems."  

We hope to send you further reports or publish some of the results on a
website.

thanks.
