The invention describes an advanced musical control system based on the identification and tracking of physical objects on an infrared touch surface. Traditional musical controllers offer limited control possibilities. Existing controllers based on object tracking systems, on the other hand, are often bulky (when based on visual detection) or restricted to the use of conductive materials (in the case of capacitive controllers). In the proposed solution, object tracking is achieved by identifying groups of points (protrusions on the objects themselves) through an infrared detection system. The geometric configurations of these points uniquely identify and localize the objects, making it possible to detect data that, once processed through suitable protocols such as MIDI, TUIO, or equivalents, allow the user to control up to three sound parameters with each hand. The invention is intended for interactive musical performance and enables intuitive and compact control of sound parameters through physical objects.
