In order to increase the recognition of autism spectrum disorder (ASD) in young children, researchers at the University at Buffalo are working on a smartphone application that could help detect autism in children as young as two years old. 
The application tracks eye movement to determine if a child is showing signs of ASD in less than a minute. 
The application, which could also be used on a tablet or PC, tracks eye movement of children while they are looking at pictures of social scenes, such as those with multiple people. The eye movement of a child with autism is different than those without the disorder. Researchers found the application had an accuracy rating of 93.96%.
