In a study from Japan, researchers used eye-tracking technology to explore early diagnosis of autism spectrum disorder (ASD). Associate Professor Mikimasa Omori from Waseda University created six pairs of 10-second videos displaying predictable and unpredictable geometric movements. These videos were shown side-by-side to children, and their eye movements were tracked using a system developed by Tobii, a Swedish company. The findings, published in Scientific Reports, revealed that children with potential ASD spent significantly more time, about 70% more, observing predictable movements compared to typically developing children. This behavior increased gradually as the videos progressed. The study suggests that this focus on predictable movements could serve as an early indicator of ASD in children as young as three years old. It also proposes incorporating a brief video observation task in routine developmental checkups for toddlers aged 18-36 months to identify those at risk for ASD.
