Individual avatar skeletal based animation feedback for assisted motion control

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.
