Related studies have shown that teaching autistic individuals through graphical symbols and pictures can more effectively allow them to learn correct communication behavior. ASD individuals use visual support in a social setting at four points. Visual material enhances the confidence of autistic individuals, encourages them to be more autonomous, systematic and predictable, while providing a more stable and constant environmental condition. Thus, different types of visual materials may be employed as reinforcements, such as photographs, cut-outs, etc., and short scene materials may be designed to visually cue autistic children. Traditional ASD individual emotion recognition training methods are mainly trained by instructors using visually supported material. For example, a simple drawing, a photo shot by a real expression or a cartoon expression picture made of the simple drawing, the real expression or the cartoon expression picture is used as a material, basic emotions including happiness, liveliness, sadness, fear and the like are used as training subjects, and during training, a patient is guided to analyze and identify the emotions, and then the emotions are mastered by completing role playing and expression matching tasks. These intervention methods can not only improve emotional cognitive abilities, but also their social skills and independence. In the intervention process, considering the avoidance of ASD individuals on the face of a real person, a mode of firstly identifying materials and then transiting to the expression of the real person is generally adopted, and a certain degree of emphasis is also given to the presentation sequence of the materials.

In the existing teaching aid, the variety of the teaching aid for basic emotion recognition of children is single, and only cards are used for recognition, so that children lack of tolerance in the teaching process, class is boring, autism children have social barriers, the existing teaching aid is difficult to restore real characters and social scenes in social reality, only cards are used as cognitive tools for basic emotion, gaps still exist between the emotion expressions of the characters in reality, and the teaching aid has abrasion phenomena in the practical process, so that the accuracy of emotion represented by the emotion characteristics in the teaching aid is affected.

With the development of robots and artificial intelligence technologies, the research and market fields begin to develop autism training equipment based on a robot platform, such as chinese patent application CN113470454a, which discloses an artificial intelligence-based autism language training device for children, and in particular discloses a technical means of using a display screen as an expression training device; however, the display screen is arranged on the abdomen of the robot, so that the cognitive disorder of the misplacement of the expression is caused for the child, and the robot of the patent application lacks shielding when the child directly observes the change of the transmission color and the expression of the human face, so that the psychological terrorism Gu Xiaoying is easily caused, namely, the human is observed to be a non-human object which is highly similar to the human, the terrorism effect is more obvious on the child, and particularly, if the child observes the distortion and misplacement of the facial image of the human, the strong terrorism and stress resistance psychology are possibly stimulated, and even psychological damage is possibly caused.
