This system was first used while Coniglio and Stoppiello were students at CalArts in 1989. For example, when a performer’s arm is straight, the sound is very soft as the performer bends her arm, the sound amplifies. Video and sound are thereby manipulated directly in relation to a specific movement.
TROIKATRONIX ISADORA CODE
This signal is then transformed into code that manipulates other theatrical equipment – video cameras or digital sound devices. When a joint moves, it sends a signal to the computer. One sensing device Troika Ranch developed and implemented is the MidiDancer a bodysuit outfitted with plastic fibers that measure the flexion and extension of the major joints on the body. A sensing device is a piece of equipment programmed to measure the movements or vocalizations of performers.
(Learn more at TroikaTronix website.)Ī typical setup for a performance or installation includes one or more movement sensing devices that communicate with an offstage computer. Isadora gathers movement information from various sensory devices and uses that information to control and manipulate digital video, music synthesizers, sound modulation devices, theatrical lighting and robotic set pieces. Created by Co-Founder Mark Coniglio, Isadora is a graphic programming environment that provides human control over digital media, with special emphasis on real-time manipulation of digital video.
TROIKATRONIX ISADORA SOFTWARE
Isadora ® is the software “brain” behind Troika Ranch performances and is the main technology used to generate the imagery and sound for Troika Ranch’s current projects. But, most importantly, it imparts a real and necessary density that mirrors the media intense world in which we live. Integrating emergent media keeps live theater vital in a world where the most widely experienced channel of aesthetic expression is broadcast media. Tools like video, digital media software packages and tele-presence are important to us because art, to be relevant in contemporary society, must simultaneously embrace and examine contemporary culture and currency. Coniglio and Stoppiello want all of the digital media in their work to have the same sense of dynamism, vitality and “liveness” as the performers themselves. This interaction allows a performer or viewer to follow their instincts from moment to moment, making improvisational choices that subtly or profoundly change the visual and aural content of a work. By using these systems a bending arm can warp a video image or the kick of a leg can recall a musical phrase. This linkage is achieved by using cutting-edge computer technology in tandem with custom sensory technology that tracks the movement and vocalization of performers on stage or viewers in an installation. Interactivity is the energetic linkage of human action to digital content and the feedback loop that is formed by this relationship – performer responds to system, system reacts to performer, performer makes informed choice to respond to system, etc.
Interactivity has been an essential and integral component of Troika Ranch’s work since the company’s inception.
