Instrumented Bodies: Digital Prostheses for Music and Dance

The Spine

Spine Sketches

The Spine is a “prosthetic” digital musical instrument developed for the collaborative project Les Gestes, in which we endeavoured to design new instruments for dancers.  The new instruments would extrapolate from the T-Stick, which we had already used in the performance Duo pour un violoncelle et un danseur with the same collaborators. Starting with foam prototypes, the Spine and its companion instruments the Rib and the Visor were developed iteratively using participatory design through frequent workshops, parallel problem solving, and digital fabrication methods. The current models are fabricated from laser-cut transparent acrylic, transparent PVC tubing, and PETg rods. The entire structure is assembled using interference fitting rather than any glues or fasteners.

The Spine tracks and reports it’s orientation and shape in real-time, accomplished through the use of inertial and magnetic-field sensing at each end of the structure. Sensor-fusion algorithms run on-board the instrument.

I have previously blogged some teaser photos and a couple of videos showing a demonstration of the orientation and deformation sensing I developed for the Spine and a promo for the upcoming shows.

Here’s a promo video for the project Les Gestes, posted by our collaborators Van Grimde Corps Secrets. The prosthetic digital instruments worn by the dancers were conceived and developed by myself and my colleague Ian Hattwick in the IDMIL.

The project is still underway, but the touring schedule has been established:

  • Montréal (Canada) – March 13-16, 2013, Agora de la danse, in partnership with live@CIRMMT
  • Lennoxville (Canada) – March 19, 2013, Théâtre Centennial
  • Arnhem (The Netherlands) – April 10, 2013, Schouwburg
  • Blanc Mesnil (Paris, France) – April 13, 2013, Forum du Blanc Mesnil
  • Bruges (Belgium) – April 18, 2013, Concertgebouw
