Rosa Dei Venti

An installation about the human will to control the god-made elements.

During the Residency at the Trasformatorio in Montealbano (Sicily), the wind was blowing so much that i wished i could stop it with a simple gesture. So i decided to build an installation in the pitch-dark long corridor of the museum of the castle to recreate the scary atmosphere of a storm at night and allow the visitors to control/play with “the elements”.

In line with the concept of the Trasformatorio, the challenge was how to create a big convincing storm sound and be eco-friendly. Usually big sound requires big expensive equipment in terms of money and energy.

I captured the sound of the wind outside and diffused it through several loudspeakers which were enough to deliver the high what do viagra and cialis do if taken together frequencies of the wind character. I used resonators to make vibrate the walls, windows and metals plates of the castle to generate a bigger, more realistic low thundery sound. Finally i programmed a wireless sensor system (powered by cell phone batteries) to allow the people to control the intensity of the wind with their hands.

The whole system could run on solar energy. During the day a solar panel would charge a car battery and during the night the electricity could power the whole installation: amplifiers, computer and sensors.

Epi::Akten light (motion tracking studies)

By Alberto Novello a.k.a. JesterN, Anthoni Rijekoff and Federica Dauri

We used a combination of technologies to create a flexible and transportable low-impact energy motion tracking system. Through the ASUS Xtion PRO LIVE interface we can determine the skeleton joint position in a 2d space. We used network communication to transfer the bodily information to a second computer for sound design, which used pre-recorded sound of Montealbano village in a concatenative synthesis fashion. This added the sense of location-specific to the raw technology.

All elements run on solar energy and have an autonomy of several hours with a completely charged car battery. The dancer was inspired by the metaphors of body giving/body receiving in her actions and could construct cialis sample pack autonomously several improvisations which were always very creative and different. The aesthetic imposed by the developed technology revolves around the concept of synchronicity of machine-human // action-reaction. Mostly the dancer decides when to trigger sound events but sometimes the unexpected sound trigger the creativity of the dancer which adds a random creative element in the aesthetic discourse.

We feel all these experimentations have big potential and will be further explored in the context of a future performance.

Epi::Akten dark (motion tracking studies)

We used a combination of technologies to create a flexible and transportable low-impact energy motion-tracking system. Through the SenseStage microcontroller boards developed by Marije Baalman at STEIM we can determine the acceleration of joint positions wirelessly. It took couple of days to understand of the accelerometer works and what kind of data is transmitted. How to stabilize/lowpass the data and eliminate jitter. At the end we use modulo of the acceleration in 3directions, so it doesn’t count the direction of the acceleration just its intensity. We finally chose to put one on each arm plus one on the back of the dancer. This choice leaves the legs free to express which seems a good compromise to have a creative output and not just a demo of a system.

The advantage of the SenseStage sensors compared to Kinect and other similar devices is the absence of a camera, thus allowing the possibility of 3d tracking (especially when joints get covered by other body parts). Another advantage is the extended space,we tried with a 30m room with perfect detection side effects of ambien 10 mg and very-low latency. Disadvantage is the estimation of the skeleton relative positions, but we think it’s possible.

Another advantage is the lightness of computation allowing one computer to do all kinds of processing. Which means also less energy impact when used with a solar energy, longer performance durations, transportability etc.

The dancer was inspired by the metaphors of body giving/body receiving in her actions and could construct autonomously several improvisations which were always very creative and different. The aesthetic imposed by the developed technology plays a lot with synchronicity of machine-human action-reaction. Mostly the dancer decides when to trigger sound events but sometimes the unexpected sound trigger the creativity of the dancer which adds a random creative element in the discourse.

We feel the experimentation have big potential and will be further explored in the context of a future performance.
