Autism Spectrum Disorder (ASD) is a developmental condition that affects communication, social skills and other behaviours. Characteristic of some cases in both children and adults is repetitive movements or unusual behaviour – stereotyped movements.
A research team from France and Morocco describe in the International Journal of Biomedical Engineering and Technology, an automated detection system for diagnosing stereotyped movements that uses the motion detector system of the “Kinect” video game. The Kinect system is based on a webcam type peripheral computer device that allows the player to control the computer through movements and gestures (as well as spoken commands via a microphone input). The Kinect was originally an add-on for Microsoft’s Xbox gaming console.
The team of Maha Jazouli of Sidi Mohamed Benabdellah University, in Fez, Morocco, and colleagues have used a $P Point-Cloud Recogniser to identify multi-stroke gestures as point clouds as recorded by the webcam component of the Kinect and its processing system for gesture and movement determination. Their new methodology can automatically detect five stereotypical motor movements: body rocking, hand flapping, finger flapping, hand on the face, and hands behind back.
