Individual Avatar Feedback Creation for Assisted Motion Control

Abstract

In Medical Training Therapy (MTT), the precise execution of the training exercises is of decisive importance for the success of the therapy. Currently, a therapist has to treat up to 15 patients simultaneously on an outpatient basis. We propose, an assistance system, can evaluate both quantity and quality of the movement performed using a target-oriented model and give recommendations for action directly to the patient by means of feedback. An avatar in traffic light colours signals in which body region an error has occurred. The individualisation of the underlying three-dimensional avatar increases the willingness of the patients to participate in the exercises without the supervision of therapist. The monitored error frequency was decreased by 50% by the assistance system.
