Acquisition of motor skills in isometric conditions through synesthetic illusions of movement

Interactive technologies can help people acquire movement skills, and one way is by using visual distortions to boost neural adaptation. An extreme version of such approach is to train a movement without moving by creating a synesthetic illusion of movement - displaying virtual motions when there is none. While this approach uses no proprioceptive error to drive adaptation, our results show encouraging evidence that motor skills can be acquired through such illusions of movement.
