HAND-FORMS
IN HYBRID LIGHT | The Manual
Input Sessions is a series of audiovisual vignettes which probe the expressive
possibilities of hand gestures and finger movements. Our concert is performed
on a combination of custom interactive software, analog overhead projectors and
digital computer video projectors. The analog and digital projectors are aligned
such that their projections overlap, resulting in an unusual quality of hybridized,
dynamic light. During the performance, a computer vision system analyses the sihouettes
of the performers� hands as they scribble on transparencies, and move across the
glass tops of the overhead projectors. The hand gestures and transparency drawings
are then analysed by our custom software. In response, our software generates
synthetic graphics and sounds that are tightly coupled to the forms and movements
of the performers� actions. The synthetic responses are co-projected with the
organic, analog shadows, resulting in an almost magical form of augmented-reality
shadow play. | | BIOGRAPHIES |
Golan Levin
(http://www.flong.com)
is an artist, engineer and composer interested in developing artifacts and events
which explore supple new modes of interactive expression. His work focuses on
the design of systems for the creation, manipulation and performance of simultaneous
image and sound, as part of a more general inquiry into non-verbal communications
protocols in cybernetic systems. He is known for the conception and creation of
Dialtones
(2001), a concert whose sounds are wholly performed through the carefully choreographed
dialing and ringing of the audience's own mobile phones, and for The
Secret Lives of Numbers (2002), an interactive online data visualization
featured in the 2004 Whitney Biennial. Levin is Assistant Professor of Electronic
Art at Carnegie Mellon University, Pittsburgh. Zachary
Lieberman (http://www.thesystemis.com)
is an artist, engineer and educator whose work explores the creative and human
uses of technology. He produces installations, on-line works and concerts concerned
with the themes of kinetic and gestural performance, interactive imaging and sound
synthesis. Lieberman lives and works in New York City, where he teaches courses
in audiovisual synthesis and creative image processing at Parsons School of Design.
Most recently, Lieberman and Levin have premiered several works exploring visual
treatments of real-time speech analysis, including RE:MARK
(2002), an interactive installation, and Messa
di Voce (2003), an interactive-media performance. |
