scoreLight synesthesia laser tracking

"scoreLight" is a prototype musical instrument capable of generating sound in real time from the lines of doodles as well as from the contours of three-dimensional objects nearby (hands, dancer's silhouette, architectural details, etc). There is no camera nor projector: a laser spot explores the shape as a pick-up head would search for sound over the surface of a vinyl record - with the significant difference that the groove is generated by the contours of the drawing itself.

Sound is produced and modulated according to the curvature of the lines being followed, their angle with respect to the vertical as well as their color and contrast. Sound is also spatialized; panning is controlled by the relative position of the tracking spots, their speed and acceleration. "scoreLight" implements gesture, shape and color-to-sound artificial synesthesia; abrupt changes in the direction of the lines produce trigger discrete sounds (percussion, glitches), thus creating a rhythmic base (the length of a closed path determines the overall tempo).
