Head Orientation Monitoring with Wearable RFID for Detection of Lateral Glance of Children with Autism Spectrum Disorder
Some children with Autism Spectrum Disorder (ASD) show a symptom called lateral glance, which is a tendency of looking at objects out of corner of eye by turning head in the opposite direction. Since the lateral glance can negatively affect the muscles around the eyes and social interaction of the children, timely diagnosis, tracking and correction is very important. To overcome the limitations of the current eye-tracking device, a novel sensor using RFID (radio-frequency identification) tag was introduced. Four RFID tags were attached to the forehead area of a hat in two rows, and in each row difference of RSSI (Received signal strength indicator) of the tags were calculated. Result showed high correlation (>.93) between the sensor tracking and the head orientation angle which is the ground truth. RFID tags mounted on a hat showed a possibility of a battery-less, light and inexpensive wearable device for the children with ASD.
