Because children with autism cannot carry out normal language and social activities, parents and teachers cannot fully understand their specific interests. But the eyes can express their thoughts and feelings and subtle feelings that are difficult to express with words. By tracking children's eye trajectories in real time, they can perform natural eye movement interactions in contextual classified scenes, and perform interest screening and analysis based on the gaze data of the hierarchical interest screening content. After a comparative experiment, the subjects' real eye movement intentions are consistent with the test intentions. According to this method, the children with autism can communicate effectively with their points of interest.
