Joseph Malloch en Ian Hattwick , twee promovendi aan de McGill University’s Input Devices and Music Interaction Lab (IDMIL) , werkten samen met een team van dansers , musici , componisten en choreografen aan de ontwikkeling van draagbare digitale instrumenten voor een live muziek- en dansoptreden.

Hun doel was om geavanceerde detectie technologieën te gebruiken om instrumenten te ontwikkelen die visueel opvallend , maar robuust genoeg waren om gebruikt te kunnen worden in dansvoorstellingen. De producten zijn geprint met een 3D-printer en geven licht vanuit de binnenkant door LED-verlichting.

“We wanted to create objects that were beautiful, that were functional and that were believable as both instrument and as an extension of the performer’s body”, aldus Malloch en Hattwick.

Each of the Ribs and the Visors is constructed from a solvent-welded sandwich of laser-cut transparent acrylic and polycarbonate. One of the layers uses a transparent conductive plastic film, patterned with the laser cutter to form touch-sensitive pads.

The pads are connected to the electronics in the base of the object using very thin wire, run through laser-etched grooves in the acrylic. The electronics in the base include a 3-axis accelerometer, a ZigBee radio transceiver, circuitry for capacitive touch sensing, and drivers for the embedded LEDs. Li-Ion batteries are used for power.

Each of the Spines is constructed from laser-cut transparent acrylic vertebrae threaded onto transparent PVC hose in a truss-like structure. One of the rails in the truss is a thin, very flexible length of PETg plastic that can slide through the holes in the vertebrae, allowing the entire structure to bend and twist. The PETg rod is fixed at both ends of the instrument using custom 3D-printed attachments.

For sensing, the Spines use inertial measurement units (IMUs) located at each end of the instrument – each a circuit-board including a 3-axis accelerometer, a 3-axis rate gyroscope, a 3-axis magnetometer, and a micro-controller running custom firmware to fuse the sensor data into a stable estimate of orientation using a complementary filter.


De protheses worden aangedreven door sensoren en draadloze data- transceivers en activeren bij aanraking. Als de dansers hun lichaam bewegen, wordt muziek gespeeld .
