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. Recently an assistance system that can assess both the quantity and the quality of movement was developed. A feedback system models target-oriented recommendations for actions and communicates them directly to the patient. A hardware accelerated visualisation system using OpenGL and GLSL shaders was realised to animate a real-time rendered 3D mesh connected to an extracted motion skeleton. An avatar visualises the error by colouring the body regions with traffic light trenches. The individualisation of the underlying three-dimensional avatar increases the willingness of the patients to participate in the exercises which they perform autonomously without the supervision of therapists.
