Assisting the practice of motor skills by humans with a probability distribution over trajectories

In sports training, rehabilitation or in the practice of motor skills in general, errors in the execution of movements may go unnoticed when a human instructor is not available. In these situations, a computer system or robotic device able to detect movement errors and propose corrections could be helpful. This extended abstract presents an approach for detecting errors in the execution of movements and for providing feedback to the user in order to correct these errors.
