Real time Kinect evaluation of therapeutical gestures

This paper presents a recognition scheme for therapeutical gestures by using data from a Kinect sensor. Experimental studies are conducted to determine whether the proposed calculation of angles relevant for the definition of therapeutic gestures yields results that can be used to determine, if the movement is being correctly executed. Calculation of the angles using information from two Kinect sensors is performed in order to determine, if it produces a significant improvement in the robustness of the angles used for recognition. The results show that the calculation of the angles formed with the planes of motion is robust enough for a wide variety of therapeutical gestures. They also show that unless the movement is directed towards the sensor the improvement with the use of two Kinects is marginal when calculating the angles of interest.
