System introduction: music is adopted in the system to guide trainees' emotional state and regulate their nerve excitability. The unique dual-screen display technology enables the main vision of both eyes of the trainees to fall on two screens respectively. Through the screen, the visual channels of the left and right eyes are interactively stimulated to wake up the activity of the trainees' cerebral cortex. With brainwave lighting mode, trainees can enter corresponding physiological state, improve their concentration, promote their learning, and improve their cognitive and emotional control abilities

Scope of application: it is applicable to children with hearing impairment, language retardation, mental retardation, autism, cerebral palsy and other special groups with articulation, speech and speech disorders, and it is applicable to rehabilitation institutions of disabled persons' federation at all levels, special education institutions at all levels, and various rehabilitation and training institutions.

System function parameters:

1. Scale testing function: the related evaluation of ABC scale, conners rating scale and speech behavior scale of autism can be carried out.

2. Training program: according to different characteristics of trainees, establish corresponding files of trainees, evaluate them, and design targeted audio-visual courses according to the evaluation results and their own characteristics. The training of trainees includes emotional regulation, learning promotion and other related training.

3. Archive query: all previous scale evaluation results and courses and training of patients can be inquired and viewed in real time, providing basis for the design of personalized program.

4. Audio-visual music: this module USES the regulation principle of audio-visual rendering and is designed according to the principle of music treatment and multi-sensory stimulation. By changing the related properties of music, it regulates the corresponding neural excitability of trainees, promotes their learning, and finally improves their cognitive and emotional self-regulation ability

5. Emotional cognition: there are two major training programs: expression cognition and emotional experience.

6. Social behaviors: including voice recognition, self-care, social themes, situational simulation and role-playing training programs.

7. Recognize sounds: provide various types of sound stimuli to help them learn to listen.

8. Self-care in daily life: it is composed of behavioral learning, behavioral shaping and behavioral strengthening.

9. Social themes: train with different themes. Through training and teaching of appropriate behaviors in different situations, children with behavioral disorders are helped to deepen their understanding of daily life situations, guide them to shape good behaviors and habits, and thus improve their social skills.

10. Scene simulation: use multimedia 3D rendering technology to simulate the real scene, and let trainees find out the incorrect behaviors in the scene and correct them, so as to form correct social behaviors.

11. Role playing: the main character of video is taken as the role object to present the commonly used communication skills. Through role playing, the behavior of trainees is regulated, so as to improve the communication ability of children.

12. Structured teaching: structured teaching emphasizes the systematic arrangement of teaching environment, materials and procedures so that trainees can learn from them. Including visual structure, environmental structure, routine, program schedule and personal work system five content introduction and related training.

13, ecological teaching platform: according to the actual needs, can add, choose, input named pictures, input prompt voice, input prompt text, import video files, make it no longer subject to language, culture, region and other factors bound and restricted.
