Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is assumed to give rise to the experience of seeing. The problem with this kind of approach is that it leaves unexplained how the existence of such a detailed internal representation might produce visual consciousness. An alternative proposal is made here. We propose that seeing is a way of acting. It is a particular way of exploring the environment. Activity in internal representations does not generate the experience of seeing. The outside world serves as its own, external, representation. The experience of seeing occurs when the organism masters what we call the governing laws of sensorimotor contingency. The advantage of this approach is that it provides a natural and principled way of accounting for visual consciousness, and for the differences in the perceived quality of sensory experience in the different sensory modalities. Several lines of empirical evidence are brought forward in support of the theory, in particular: evidence from experiments in sensorimotor adaptation, visual \"filling in,\" visual stability despite eye movements, change blindness, sensory substitution, and color perception.

Synopsis There is a growing body of literature associating abnormal scapular positions and motions, and, to a lesser degree, clavicular kinematics with a variety of shoulder pathologies. The purpose of this manuscript is to (1) review the normal kinematics of the scapula and clavicle during arm elevation, (2) review the evidence for abnormal scapular and clavicular kinematics in glenohumeral joint pathologies, (3) review potential biomechanical implications and mechanisms of these kinematic alterations, and (4) relate these biomechanical factors to considerations in the patient management process for these disorders. There is evidence of scapular kinematic alterations associated with shoulder impingement, rotator cuff tendinopathy, rotator cuff tears, glenohumeral instability, adhesive capsulitis, and stiff shoulders. There is also evidence for altered muscle activation in these patient populations, particularly, reduced serratus anterior and increased upper trapezius activation. Scapular kinematic altera...

Formation and control of optimal trajectory in human multijoint arm movement : minimum torque-change model

In this study, we investigated the ability of blindfolded adults to discriminate between concave and convex auditory virtual surfaces. We used a Leap MotionTM device to measure the movements of the hand and fingers. Participants were asked to explore the space above the device with the palm of one hand and an auditory feedback was produced only when the palm was moving into the boundaries of the surface. In order to demonstrate that curvature direction was correctly perceived by our participants, we estimated their discrimination thresholds with a psychophysical staircase procedure. Two groups of participants were fed with two different sonification of the surface. Results showed that most of the participants were able to learn the task. The best results were obtained with an auditory feedback related to the component of the hand velocity tangential to the virtual surface. This work proposes a contribution to the introduction in virtual reality of auditory virtual objects.

The literature on gesture-sound interactive system and sensori-motor learning is scattered in separate different research domains and communities, such as Sound and Music Computing, Neurosciences, Interactive Sound Design, Sonification, Rehabilitation, Sport Sciences.
The large majority of neuroscience papers on the human motor system deals with visual, haptic and vestibular sensory inputs and rarely mention the auditory modality. Historically most of papers that report on auditory-motor mechanisms concerned speech learning and production. On one hand, due to promising applications in movement learning (mostly in sport) and rehabilitation, there is an increasing number of studies showing the potential interest of auditory feedback. The technology used in these types of applications remains generally rudimentary. On the other hand, the most advance interactive gesture-sound systems are found in the music and computing field, but lack of systemic studies evaluating these systems. Moreover, no studies are reported on sensori-motor learning.
The aim of this document is to review the literature related to the use of gesture-sound interactive system linked to different applications, namely sonification for movement learning, motor rehabilitation with auditory feedback, digital musical instruments and sonic interaction design. The document starts with a short review of important concepts and definition related to sensorimotor control and feedback. 
Due to the constantly increasing number of papers published in these area, we considered this document as a work in progress.

Sensori-motor Learning in Movement-Sound Interactive Systems: a Review

Most studies on the regulation of speed and trajectory during ellipse drawing have used visual feedback. We used online auditory feedback (sonification) to induce implicit movement changes independently from vision. The sound was produced by filtering a pink noise with a band-pass filter proportional to movement speed. The first experiment was performed in 2D. Healthy participants were asked to repetitively draw ellipses during 45 s trials whilst maintaining a constant sonification pattern (involving pitch variations during the cycle). Perturbations were produced by modifying the slope of the mapping without informing the participants. All participants adapted spontaneously their speed: they went faster if the slope decreased and slower if it increased. Higher velocities were achieved by increasing both the frequency of the movements and the perimeter of the ellipses, but slower velocities were achieved mainly by decreasing the perimeter of the ellipses. The shape and the orientation of the ellipses were not significantly altered. The analysis of the speed–curvature power law parameters showed consistent modulations of the speed gain factor, while the exponent remained stable. The second experiment was performed in 3D and showed similar results, except that the main orientation of the ellipse also varied with the changes in speed. In conclusion, this study demonstrated implicit modulation of movement speed by sonification and robust stability of the ellipse geometry. Participants appeared to limit the decrease in movement frequency during slowing down to maintain a rhythmic and not discrete motor regimen.
