With the continuous advancement of technology and the development of sensor technology and data science, autism diagnosis technology has developed rapidly, and children with autism can be diagnosed earlier. However, there is no effective treatment so far. Comprehensive rehabilitation can only be implemented through early intervention methods. To improve the effect of early intervention on the cognitive learning of autistic children and overcome the limited focus, lack of interest to small children, and other problems in traditional cognitive learning, we designed an interactive cognitive training tool for cognitive learning of the characteristics of color for autistic children. The training tool uses LED display technology, voice recognition technology, and IR positioning technology to realize the interactive design of color recognition training for autistic children.
