Doubles is an electronic music instrument with a tangible user
interface. Using two physical objects on a table, several
simultaneous performers can interact with the instrument which
registers the speed, distance, and motion of the objects. The
surface of the table is paved with beads that roll when the
physical objects are moved. This creates a sliding effect of
acceleration and a centrifugal force is created to compute the
audio and visuals in the installation. Check out the video below
to see the visuals and hear the strange sounds produced by the
instrument.
