The aim of this work is to provide jugglers with gestural control of music. This is based on the willing to control music by recycling mastered gestures generated by another art. Therefore we propose the use of a gestural acquisition system based on the processing of the electromyographic signal. The recordings are done during a three-ball cascade, of electromyogram from chosen muscles, which play a specific role in the juggling gesture. Processing of those signals is proposed in order to control musical events by means of parameters related to juggling gesture. [authors sumamry]

This paper presents the training of juggling skills, a highly complex problem of coordination, under tight time and space constraints. This training is achieved with a simple training platform, a light weight juggling platform (LWJ), and is compared to training with real balls. The principle directing the design of the platform is to obtain a simple tool. The simplification, in comparison to real world juggling, is based on the identification of invariant properties in the spatiotemporal coordination of intermediate and expert jugglers. Two classes training solutions were added to the LWJ: An audio-tactile pacing or augmented multimodal environment, and the manipulation of cognitive components of the juggling skills. The transfer to juggling with real balls was evaluated in four different experiments. [authors summary]

Elementary reactive behavior can be improved in the case of cross-modal sensory interactions thanks to underlying multisensory integration mechanisms. Can this benefit be generalized to a challenging ongoing perceptive-motor performance? We choose a juggling task to examine this question. A central issue wellknown in juggling lies in establishing and maintaining a specific temporal coordination among balls, hands, eyes and posture. Here, we tested whether providing additional timing information about the balls and hands motions by using external sound and tactile periodic stimulations improved the performance of jugglers. Results indicated that specific combination of auditory and tactile metronome led to a decrease of the spatiotemporal variability of the juggler’s performance. A contrario, degraded performances were obtained in the case of unimodal tactile metronome. We discuss these results in view of the understanding of the neuronal integration process implied in the audio-tactile interaction, and considering the well-known gating effect of movement on vibrotactile perception.
