Demonstrates combined oscillator frequency variation, amplitude variation, and triggered Drum sample ("Drumming by Dancing") modes along with Drancel RGB monitor visuals projected onto the "Drancer" performer.

For this demonstration two hand-held WiiTM Remotes on a MacBook Pro were used. (The original Drancing accelerometer suit (since 1997) used 5 triaxial accelerometers in a "body star" pattern").

Terminology: A Drancer is an "acceleration avatar" of the Drancing accelerometer music and visuals system

Because Dr Darren's Drancing accelerometer music and visuals synthesis system employs specifically acceleration, it has a special kind of "acceleration avatar" called a Drancer, where typically one Drancing performer (also known as a Drancer) typically wears 5 triaxial accelerometers in a "body star" pattern (reminiscent of Da Vinci's Vitruvian Man), which map to 3D Drancel RGB virtual synthesis atoms in the Drancer's acceleration avatar.

However, unlike many motion capture animation systems (such as those used in big budget films), where the emphasis is on spatial location, the Drancing system focuses "organically" on acceleration signals. So although the Drancer avatar can be represented in a physical space to remind us of the body star configuration, the mapped positions and perturbations (driven by conditioned accelerometer signals) of each virtual Drancel RGB in synthesised Drancing visuals are not intended to precisely reflect spatial positions.

So why does Drancing embrace acceleration alone in this way ? Because acceleration - unlike velocity or position - does not need a reference system, and this means that the Drancing system is in principle (and by design) able to be used anywhere, over a very large region, while riding your bike, or exercising, or dancing, or jogging, anywhere, anytime, even underwater or in space, without the need for a reference system.

I present here, as adapted Unified Modeling Language™ (UML™) structure diagrams, a simplified model of the hardware, data acquisition, and JSyn audio synthesis circuits of an earlier version of DranceWare for Drancing.


$dr$ of Webel is a Pure Data (PD) enthusiast. A PureData-based audio synthesis version of the DranceWare software for The Drancing accelerometer music "air instrument" uses GEM to synthesis rich visuals in real-time from accelerometer signals (such as WiiTM Remote signals), synchronised with the accelerometer music. The PLAY music project "sound circles" animated logo is synthesised using PureData/GEM, as described in this mini-tutorial

R & D: the Drancing accelerometer real-time music synthesis "air instrument" and Drancel body motion visuals

21/07/2008 - 31/08/2008
Developer and inventor, video editor

Adapted the Drancing gestural performance air instrument system to use PureData/GEM patch-based synthesis and Nintendo Wii remote controllers as wireless 3D accelerometers via Bluetooth for real-time generation of music and visuals from human movement and dance. Edited videos and educational online screenshots of the patch-based synthesis.

Created the LED-based Drancel system for translating body movement into light shows and visuals.
