Anatta is a real-time interactive dance performance that blends
interactive technology and performative art in such a way that neither
element dictates how the other proceeds. Via laser-tracking, the mostly
monochrome projections on the installation space’s walls and floor react
to the movements of dancer Joanna Gruberska (PL) and vice-versa. The
result is reciprocal interplay among the human body, the projection and
the performance space, whereby the boundary between action and reaction
becomes blurred.
Backbone of this performance is a cinder app (actually two synced
apps) with parameterized glsl shader, tuio, ableton (through OSC)
Developed and premiered in Ars Electronica's Deep Space, 4k 16x9m
wall projection, 4k 16x9m floor projection, tracking system consists of
6 LiDAR's (developed by Otto Naderer (Futurelab))
Beautiful work. Loved the play between negative and positive spaces.
Ryoji Ikeda influence is very appropriate. Could you describe the
tracking system?
Could you explain a bit more about the tracking? I checked out this
lidar range finder, and it seems it is used for robotics, measuring the
distance from the robot in 240 degrees for example. So I might be wrong,
but I imagine this as you get like 1024 numbers, which tell the distance
from the sensor. Is this right? How can you use this then? Are you
putting the sensors on stage on the sides and corners, and combine the
information coming from the sensors? How do you find this compared to
the usual camera-based tracking setup? I assume this is easier to setup
on this large scale than the camera based solution.
