Description

Teaching aid for identifying obstacles by faces of autistic children

Technical Field

The invention relates to the technical field of autism rehabilitation training, in particular to a teaching aid for recognizing obstacles by faces of autism children.

Background

Research shows that teaching autistic individuals through graphic symbols and pictures can more effectively enable them to learn correct communication behaviors. ASD individuals exercise visual support in a social setting with four points. The visual material enhances the confidence of the autistic individual, encourages them to be more autonomous, systematic and predictable, while providing a more stable and consistent environmental condition. Thus, different types of visual materials can be used as reinforcements, such as photographs, cut pictures, and the like, and short pieces of scene materials can be designed to visually suggest autistic children. Traditional ASD individual emotional cognitive training methods are mainly trained by instructors using visually supported materials. For example, simple strokes, photos shot by real human expressions or manufactured cartoon expression pictures are used as materials, basic emotions including joy, anger, sadness, fear and the like are used as training subjects, during training, a patient is guided to analyze and recognize the emotions, and then the emotions are mastered by completing tasks of role playing and expression matching. These intervention methods can not only improve emotional cognitive abilities, but also their social skills and independence. In the intervention process, in consideration of avoidance of an ASD individual on the face of a real person, a mode of recognizing a material first and then transitioning to the expression of the real person is generally adopted, and the presentation sequence of the material is also specified to a certain extent.

In the current teaching aid, teaching aid variety to children's basic emotion recognition is single, and only discern with the card, make children lack patience at the teaching in-process, the classroom is boring, there is social obstacle in autism children, current teaching aid is difficult to restore real personage and social scene among the social reality, the emotion expression of personage still exists the gap in cognitive instrument and the reality of only regarding as basic emotion with the card, and the teaching aid has the wearing and tearing phenomenon in the practical process, influence the accuracy of the emotion that the emotion characteristic shows in the teaching aid.

With the development of robots and artificial intelligence technologies, autism training devices based on robot platforms are beginning to appear in the research and market fields, such as chinese patent application CN113470454A, which discloses an autism children language training device based on artificial intelligence, and specifically discloses a technical means using a display screen as an expression training device; however, the display screen is arranged on the abdomen of the robot in the patent application, which causes cognitive disorder of facial expression position dislocation for the infant, and the robot in the patent application lacks occlusion when the facial expression is switched, so that when the infant directly observes the change of color and facial expression sent by the human face, psychological "terror valley effect" is easily caused, i.e. terror psychology generated when the human observes a non-human object which is highly similar to the human face, the terror valley effect "is more obvious on children, and especially, if the children observe the distortion and dislocation of the human facial image, strong terror psychological stress can be excited, and even psychological damage can be caused.

In addition, the existing robot or toy with replaceable expressions, particularly the expression component with a 3D profile, has the problems that the conversion gap is large, and fingers of children are easily injured by clamping during conversion.

An effective solution to the problems in the related art has not been proposed yet.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As described in the background art, the prior art has shortcomings, and in order to solve the technical problems, the present application provides a teaching aid for identifying obstacles by facing autistic children.

The first embodiment is as follows:

referring to fig. 1-9, a teaching aid for identifying obstacles to faces of autism children comprises a shell 1 and a shelter 2, wherein a face window 3 is formed in the upper portion of the front face of the shell 1, an emotion cylinder 4 is attached to and rotationally matched with the inner wall of the shell 1, and a plurality of expression features 6 are mounted on the emotion cylinder 4;

when the driving component 7 drives the shelter 2 to cover the face window 3, the driving component 7 synchronously drives the triggering component 8 to move, so that the power source 9 is in power connection with the emotion cylinder 4, the triggering component 8 moves to enable the pressing component 10 to relieve the limit on the emotion characteristics 6, the emotion characteristics 6 are enabled to be converted from being protruded from the opposite face plate 5 to being hidden in the face plate 5, when the pressing component 10 relieves the limit on the emotion characteristics 6, an avoiding space is formed, and the avoiding space is used for enabling the power source 9 to drive the emotion cylinder 4 to rotate around the central axis of the shell 1 through the triggering component 8 so as to enable the emotion characteristics 6 at the face window 3 to be switched;

when the drive assembly 7 drives the barrier 2 back to expose the facial window 3 (subject to the barrier returning to its original position to block the facial window), the trigger assembly 8 causes the biasing assembly 10 to compress the expressive feature 6 to limit its position, thereby switching the expressive feature 6 from being hidden within the face plate 5 to protruding relative to the face plate 5.

Further, the shape of the shell 1 is preferably a real model shape, a cartoon character shape, etc., the cartoon character is taken as an example for explaining the invention, and in practical application, the real model shape is preferably used for facilitating the discrimination of children on human faces in real life so as to sense the emotion of the character.
