This study investigates the human ability to perceive biological movements through friction sounds produced by drawings and, furthermore, the ability to recover drawn shapes from the friction sounds generated. In a first experiment, friction sounds, real-time synthesized and modulated by the velocity profile of the drawing gesture, revealed that subjects(More)
The present study investigated the effect of handwriting sonification on graphomotor learning. Thirty-two adults, distributed in two groups, learned four new characters with their non-dominant hand. The experimental design included a pre-test, a training session, and two post-tests, one just after the training sessions and another 24h later. Two characters(More)
Even though we generally don't pay attention to the friction sounds produced when we are writing or drawing, these sounds are recordable, and can even evoke the underlying gesture. In this paper , auditory perception of such sounds, and the internal representations they evoke when we listen to them, is considered from the sensorimotor learning point of(More)
The dynamic features of sounds make them particularly appropriate for assessing the spatiotemporal characteristics of movements. Furthermore, sounds can inform about the correctness of an ongoing movement without directly interfering with the visual and proprioceptive feedback. Finally, because of their playful characteristics, sounds are potentially(More)
This paper presents an experiment dealing with the senso-rimotor relation between auditory perception and graphical movements. Subjects were asked to synchronize their gestures with synthetic friction sounds. Some geometrical and dynamical parameters of the motor productions are analyzed according to the different mappings. This preliminary experiment(More)
The perception and production of biological movements is characterized by the 1/3 power law, a relation linking the curvature and the velocity of an intended action. In particular, motions are perceived and reproduced distorted when their kinematics deviate from this biological law. Whereas most studies dealing with this perceptual-motor relation focused on(More)
