Musical Navigatrics

Musical Navigatrics extends our previous work on passive, tangible musical interfaces, first demonstrated in our Musical Trinkets project. The Navigatrics hardware has several enhancements, including the ability to drive three mulitplexed reader coils (allowing, for example, independent degrees of control along the horizontal axis for a planar coil arrangment), higher position and frequency resolution, and a stabilized sweep oscillator. Most tags also have switches that allow them to be activated and deactivated on the fly, enabling their associated parameters to be conviently latched. The Navigatrics musical mapping also attempts to go beyond the simple, direct, music "toy" environment of Musical Trinkets, allowing dynamic assembly and complex manipulation of musical sequences. Any action with the tagged interfaces can also be dynamically recorded, played, and overdubbed with other control manipulations, allowing a Musical Navigatrics performance to achieve a high level of complexity and sonic density.

An older clip (15.3 Meg) from December 2001 showing an early version of the system when a primitive Navigatrics mapping was being tested
