Next Monday, the Performance “Augmented Body and Virtual Body II - netBody” will take place at Acedemy of Media Arts Cologne.

Suguru Goto, from a technical, artistic, and philosophical perspective, investigates the body as a distributed phenomenon which involves questions about the other, identity, and postmodern culture. Deleuze and Guattari come to mind, but also topics as embodied, distributed cognition, action-perception loops, cyborg culture or posthumanism.

If you’ve been reading some Deleuze/Guattari, you might have met the idea of the Body without Organs, and also that of the Rhizome. In this context, it could be not too wrong to express the interest of Augmented Body and Virtual Body II - netBody like this:

A body cuts into the streams of de- and reterritorialisation. By this, it constitutes a block the specifity of which lies in that it is not only subject to an actualisation of the virtual in the process of de- and recodings, but also the subject of such an actualisation (the brain as a body, or as a special image under other images, as Bergson put it – my body is part of my brain). To me, identity seems to have a lot to do with a system experiencing that its parts makes a whole just in the sense that e.g. the hand you can observe do all these things for you simply does not leave you (this maybe is opposed to a constitution in the sense of mirror stage).

Thus, the body seems to be double: On the one hand, it constitutes a natural kind, a system demarkating itself in constantly performing a homeostasis. Mechanism connects here. On the other hand, there is meaning (maybe not signs in particular, but see the notion of the body as double in Sybille Krämer: Does the body disappear? In: Seifert, Kim, Moore (Eds.) Paradoxes of Interactivity, Bielefeld: transcript, 2008 (in print)). Social processes which actualise themselves in this peculiar domain are bound to ideological conceptions. By that, one can say that it is also ideas that cut into the streams, viz. in the order of language (which is the main topic of Deleuze’s The Logic of Sense).

This is the field on which Augmented Body and Virtual Body II - netBody plays. You might have a body that is not completely yours. It functions in the context of nature as well as culture. E.g., bodies are defined by natural neccessity and possibility, as well as by social images of the order of representation, but also here there is possibility (e.g. performance), and the very processes which constitute its meaning. Now, technology sets a starting point for bringing the interactions between these two orders to attention. Conceptions of physical and social identity, physical and social alienation are spotlighted the moment that your body is not yours.

Being opened to the outside means engaging in processes which can control you, which might hurt you. You feel. Your body is controlled from the outside. You are a cyborg. You are a machine (D&G, but also Wiener: Cybernetics or Control and Communication in the Animal and the Machine). What is this that happens to you? And what do you have to do with it?

Let me elaborate on the net-aspect another time ^^;

I can only tell you this much: If you’re too far away (or just too immobile to attend ^^), you can also see the whole thing on Second Life (no exclamation mark, although this is an interesting aspect). Projections from Real Life will be seen in Virtual Reality, and Projections from VR will be seen in RL. You can get there by this link: netBody on SL. Also, feel free to take a look here Rob’s blog, and here Academy of Media Arts Cologne.

Did I mention that I have been becoming a posthumanist recently?

^^ Some of you might have got that already, so here’s another piece of that from the last couple of months.

I mentioned this Robotic Exoskeleton in the foregoing post, so let me tell you some more about it. It is part a a perfomance artwork by Suguru Goto. I was, together with a couple of other persons, involved in the development of the shoulder mechanism. What we did was figuring out how a wearable, computer-controlled mechanism could be achieved that would allow for a a human shoulder joint to be externally controlled. We did some research into anatomy, mechanics/mechatronics, work out some ideas, built some simple prototypes, and finally came up with what we got now. It is quite a simple mechanism consisting of two motors per shoulder. Lots of testing and adjustment followed. Then it had to be integrated with other parts, i.e. elbow-, wrist-, and head control. Suguru came up with a lot of that. Here’s him and the Exoskeleton in an in-between stage:

The performance will be next Monday, a post on this is following soon. Everybody will be invited!

Let me just give you an impression of the robot exoskeleton I and some other people (don’t want to reveal too much at this point) have been working on for some time. We’re not finished at all, and what you can see in the video is the person controlling the skeleton and not the other way round, because the motors did not wanna work today … Anyway, I guess you already got it: the movement of the person in this suit is going to be controlled by someone else …

I’m running OS X 10.5 Leopard on a G4 PowerBook, and I was having some issues making Macports work.

When i installed from GUI, using the Macports 1.6.0 .dmg version, at the end of installation I got something like “Installation Failed” which I slowly figured out to possibly be due to problems with my bash environment, since it was the post-flight script at the end of the installation process which could not be executed correctly - setting the PATH and MANPATH values is one of its jobs. This got affirmed by my bash environment missing the required settings.

Changing those manually usually is quite easy. On opening a bash shell, the .profile script would be executed. It would contain two Macports-related lines, namely:

export PATH=/opt/local/bin:/opt/local/sbin:$PATH
export MANPATH=/opt/local/share/man:$MANPATH

Anyway, this did not work on my system. I miss the .profile file at all, and creating it with the required entries does not change a thing. Leopard seems to have brought some changes that other users were experiencing as well. Actually, there is some posting on this issue, but it’s mainly inconclusive. On my friend’s machine (10.5, Intel) it just seems to work that way. So the problem seems to lie in the fact that different systems can have different bash scripts (~/.bash_profile, ~/.bash_login, ~/.profile …).

That all really confused me. Fortunately, I met the mighty Christoph Lischka yesterday ^^. My problem is solved now, Macports up and running, my mind can peacefully flow over with what I found out:

The bash startup scripts are executed in this order: First, the /etc/bashrc, which is a system-wide setting and which I was recommended not to change at all. Second, ~/.bash_profile. Anyway, the X Windows system evaluates ~/.bashrc first. So here’s what the latter two files look like now:

~/.bash_profile:
source .bashrc

~/.bashrc:
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
export MANPATH=/opt/local/share/man:$MANPATH

May 2nd, 2008, Morgan Packard will give a concert at FYW (Cologne Ehrenfeld). Please see flyers below.

Together with Ezekiel Honig, Morgan Packard released on acclaimed Microcosm Music NY (alongside Miskate et al. taking a naturalist, or corporeal turn towards sampling in electronic (dance) music), later on Anticipate Recordings which through his album “Airships Fill The Sky” and releases by Ezekiel Honig, Mark Templeton, Klimek, and Sawako became co-defining for contemporary music – don’t miss the freely downloadable Summer Tour Remixes!

Airships Fill The Sky, by employing instrumental elements, sampling and synthesis – i.e. representation, performance and simulation – poses questions about relations between sound, music, nature, motion, feeling, technology and mind. Packard plays the accordion in a way that investigates material properties of the instrument in an expressive context – the instrument not mainly as a tool to express artistic or musical concepts, but as a body expressive of itself, of its physical properties and meanings, which cannot just be infererred by myself and applied to an otherwise dead matter, but are in direct relation to this thing, and of homologous properties of a human body – the instrument breathes, feels, as I synchronise my breath, my feeling.

Here, already, simulation takes place: Myself as a mind–body, capable of conveying a universal connection between sense and matter, cannot only acknowledge the expressiveness of the instrument and the processes that surround it, but I can reflect and describe all this (what I maybe need representational power to) in order to communicate. This becomes possible as feeling is in all things, and breathing in it’s meaningful, expressive aspects relies on my knowing about how it feels to have a body which breathes.

Thus, the instrument becomes part of myself in a twofold sense: its breathing as breathing is simulated in my capability to abstract from my own concrete bodily states and draw the meaning of a thing breathing from my own breathing (it breathes through myself, or technically: I run a simulation of it breathing on my hardware, which is not all that ‘hard’, as it/myself knows about breathing); and my own breathing as breathing becomes realised in the instrument, i.e. the instrument is an integral part of my conception of breathing, of its meaning, of what it is for myself.

Sure, there’s a stricter way to grasp simulation, which we encounter when we meet the natural beauty of the simulacrum. To make it clear, hearing the sound of SuperCollider determining the synthetic aspects of Packard’s music is bliss. But apart from this production esthetics, the simulational power of SC presents us a dynamic representation which is becoming natural – it’s arguable whether this would be representational at all, and also, whether I assume too much about the actual simulational effects here. What I hear is the following: imagine a field of hollow bamboo canes as they could be used to build panpipes. Some of them touch one another, others stand apart from one another, imagine now a process that partially blows, partially shakes these, namely with a dynamic that reminds of unsteady, but strong and playful wind rattling at your door, shaking the bamboo façade of your cozy shed.

Again we are confronted with a very much material, dynamical and sounding process, but this time probably without a body proper in the first place. Again, we do not seem to deal with an absolute disembodiment here, but with a simulation which does not consist in an irreality or disembodied virtuality, but in a virtuality consisting in ourselves which can be realised though this very simulational process.

Luckily, as I am not capable of giving a complete account for what makes me appraise Airships Fill The Sky in this manner, I will stop here. Hope to see you on Friday!

Thanks to cramo for making this happen!!

For a long time, but without success, I tried to get my Wiimote to work as a volume control for my Powerbook G4. The problem with the free software Darwiinremote always was that mapping the volume keys to Wiimote doesn’t seem possible.

That problem is partially solved now. The free software PTHVolume lets you define any other shortcut which can then be mapped to Wiimote using Darwiinremote.

Still, it’s not perfect. PTHVolume misses a customisable shortcut for the option-shift-volume combination which under 10.5 Leopard controls the volume in smaller increments. And, but that’s only an aesthetic issue, you can’t hide the PTHVolume icon from the menu bar as you can do with the normal volume icon.

Anyway, find PTHVolume here, and Darwiinremote here.

Minimal Improv Cooking can be described as a way of learning through exploring.

In cooking, there are two general elements: plan and action. Preparing good food implies a huge amount of knowledge about ingredients, tools, techniques, chemistry, physics. However, lots of (subtle) differences in resulting quality lie in the process of cooking itself. This can only be learned through experience. Often, there is no time to take another look at the recipe. Furthermore, it won’t help if the temperature is already slightly too high etc.

Minimal Improv Cooking is a way of facing this performative impasse: how can I develop my activity without already knowing everything theoretically? The principles are as follows:

• The decision about ingredients is taken intuitively. Experience provides enough knowledge about what could go well with what else. Get what you want to combine, experiment with that, and your ability will develop in the actual process.
• A complex result does not need a complex recipe. The aspect of minimality is beneficient for the preparation. If the recipe is too complex, I cannot concentrate on what I do and cannot learn from it. However, this does not imply using common, easy or familiar ingredients. I get fantastic results preparing food I’ve never eaten before.
• Look up some possibilities of preparation. Just get a vague impression – as a timing can depend on temperature, of what use is an exact time without the neccessary exact temperature? Decide which way to go, memorise the technique just roughly.
• Use your own activity for acquiring additional ability. Observe what actually happens, do not think about the result, but about the preparational process. Myself, I nearly never check the taste before serving.
• Surely, lots of things can go wrong. However, there will be no need to worry whether the recipe was!

Hegel, F./Krach, S./Kircher, T./Wrede, B./Sagerer, G. (2008), Theory of Mind (ToM) on Robots: A Neuroimaging Study

Hegel and colleagues present (preliminary) results of a neuroimaging study on Human-Robot Interaction (HRI) and Theory of Mind (ToM). What they are interested in, is whether the shape of the interacting partner (human, anthropomorphic robot, functional robot, computer) in a Prisoner’s Dilemma Game scenario would have an influence on the measured activity in ToM brain areas (medial prefrontal lobe, anterior cingulate cortex).
