Analysis of children´s posture for the bodily kinesthetic test

In this paper, we present a children´s posture analysis system using the Kinect while they are performing the yoga poses with the Nao robot. We collected posture data from eighteen children who were kindergaten kids and their posture accuracy was annotated by an expert into four different levels. For a feature extraction, we apply a method of an angular skeleton representation in every frame and those features are aggregated with several different functions over the entire sequence of each pose. We show results of the posture classification and analysis.
