In this study we collect body movements of children as they interact with a clinician during the ADOS test that is used to assess autism. We have developed a unique system of synchronized Kinect cameras that can track both the child's body movements and the clinicians body movements as they interact during a 45 minute period. We can then quantify different measures such as the distance between the therapist and child during this visit, the amount of time that the child faced the clinician, the presence of repetitive/stereotypical behaviors, and the existence of balance and postural problems. These measures give us a useful way of automatically scoring the severity of a child's social and motor problems. This is particularly useful for assessing change over time such as in response to therapy.
