This paper introduces and evaluates a novel methodologyfor the estimation of bow pressing force in violin performance, aiming at a reduced intrusiveness while maintaininghigh accuracy. The technique is based on using a simplifiedphysical model of the hair ribbon deflection, and feeding thismodel solely with position and orientation measurements ofthe bow and violin spatial coordinates. The physical modelis both calibrated and evaluated using real force data acquired by means of a load cell.
