Autism is a brain developmental disorder, and takes social communication disorder, communication disorder and repeated stereotypy as core symptoms, and individual characteristics and expression of autism have obvious heterogeneity in language, behavior and social development. According to the report of 2018 American disease control center, the incidence rate of autism of children is 1:59, the autism trend is continuously increased, the global incidence rate is about 1% -1.5%, and the autism families exceeding ten million in China face the crisis of high intervention cost and insufficient technical means at the same time, so that the autism family is developed into a social problem to be solved urgently.
Due to complex etiology, a specific treatment drug for the core symptoms of the autism does not exist, and the fact that early discovery, early behavior intervention and education can obviously improve the poor prognosis of the autism becomes a consensus of experts. This promotes the establishment of a complete diagnosis system for autism, and is particularly important for preschool children to be able to perform early screening of autism core symptoms.
It should be noted that social interaction disorder (social disorder) is a core symptom of autism spectrum disorder, and mainly manifests that social interaction with people cannot be performed through gaze following, facial expression, psychological theory, pain co-emotion and the like, it is difficult to establish a healthy attaching relationship with family members, there is no sharing and cooperation among companion interactions, and it is difficult to develop good friendship. Whether the children suffer from the autism can be analyzed by knowing the development condition of the social interaction disorder of the children.
The related technology provides a screening method, whether the expression of the autism core symptom exists in the children is determined through the collected brain wave data analysis when the children watch the animation, and the screening method can enable doctors not to be in direct contact with the children, so that the abstinence of the children is reduced, and the accuracy of screening results is improved. However, if the child is not interested in the played animation or is attracted attention by other things, the attention of the child is not focused on the animation, so that the electroencephalogram data acquired by the acquisition device may not be the electroencephalogram data of the child when the child watches the animation, thereby affecting the accuracy of the screening result. For example, when a child watches an animation, some external sounds attract attention, the child does not watch the animation, but the acquisition device still acquires brain wave data of the child, so that brain wave data of other things for the child exists in the brain wave data, and the accuracy of a screening result is affected by analyzing and determining whether the child has the expression of the autism core symptom.
In view of this, the embodiment of the application provides a screening system for social disorders, and by setting the gaze point detection device and the control device, a time period (i.e., a first time period) in which the eye movement gaze point is located in the display area and the display area displays the stimulus video can be determined, and the control device can extract electroencephalogram data (corresponding to the first time period) of a tested person watching the stimulus video from all electroencephalogram data acquired by the electroencephalogram detection device according to the first time period, so that the control device can accurately acquire the electroencephalogram data of the tested person watching the stimulus video, and accuracy of a screening result is improved.

The starting time of the display device 110 (starting to display the stimulation video in the display area), the starting time of the gazing point detection device 120 (starting to detect the position information of the eye movement gazing point of the detected person), and the starting time of the electroencephalogram detection device 130 (starting to collect the electroencephalogram data of the detected person) are not in sequence, so that the display device 110, the gazing point detection device 120 and the electroencephalogram detection device 130 can be simultaneously started, the electroencephalogram detection device 130, the gazing point detection device 120 and the display device 110 can also be sequentially started, and the application is not limited at all.
For example, during screening, in order to enable the electroencephalogram detection device 130 to acquire more electroencephalogram data, the electroencephalogram detection device 130 is firstly turned on, after the electroencephalogram detection device 130 starts to acquire the electroencephalogram data, in order to enable a tested person to completely watch a stimulus video, the fixation point detection device 120 is firstly turned on to detect the position information of the eye movement fixation point of the tested person, and after the attention of the tested person is determined to be in a display area (the eye movement fixation point is located in the display area), the display device 110 is then enabled to display the stimulus video in the display area.
Specifically, in the process that the control device 140 determines the first time period according to the position information, when it is determined that the eye movement fixation point is located outside the display area according to the position information, the control device 140 is further configured to control the display device 110 to suspend displaying the stimulation video, and when it is determined that the eye movement fixation point returns to the display area again according to the position information, the control device 140 is further configured to control the display device 110 to continue displaying the stimulation video.
Further, when the eye movement fixation point is located outside the display area, in order to enable the attention of the tested person to return to the display area as soon as possible (the eye movement fixation point is located inside the display area), the screening efficiency is improved, the control device 140 is further used for guiding and reminding the tested person so as to guide the tested person to watch the display area, and the method for guiding and reminding the tested person by the control device 140 is not limited.
For example, the control device 140 is configured to control the display device 110 to display a guidance video in the display area, so that the person to be tested looks at the display area.
Specifically, when the eye movement fixation point is located outside the display area, the control device 140 controls the display device 110 to suspend displaying the stimulus video, and also controls the display device 110 to display the guidance video (for example, a video in which a small person dances in the left-lower part, the left-upper part, the right-lower part, the right-upper part, and the center of the display area in sequence) in the display area, so that the attention of the person to be tested returns to the display area (the eye movement fixation point is located inside the display area), when the eye movement fixation point returns to the display area again, the control device 140 controls the display device 110 to stop displaying the guidance video, and controls the display device 110 to continue displaying the stimulus video, and when the eye movement fixation point is located outside the display area again, the above operations are repeated until the stimulus video display is finished, so that the person to be tested can completely view the stimulus video, and the screening time can also be reduced, and the screening efficiency can be improved.
When the eye movement fixation point returns to the display area again, the control device 140 may immediately close the guide video in the display area, control the display device 110 to continue to display the stimulation video in the display area, and may also continue to display the guide video, so as to ensure that the attention of the person to be tested can be focused in the display area, and control the display device 110 to continue to display the stimulation video in the display area after the preset time period.
For another example, the control device 140 controls the artificial intelligence voice interaction module in the display device 110 to send out a guidance voice to remind the person to be tested to watch the display area.
Specifically, when the eye movement fixation point is located outside the display area, the control device 140 controls the display device 110 to suspend displaying the stimulation video, and at the same time, controls the artificial intelligence voice interaction module to send out the guidance voice (for example, "XXX", please see the animation video ") to remind the person to be tested to continue watching the stimulation video, when the eye movement fixation point returns to the display area again, the control device 140 controls the artificial intelligence voice interaction module to stop sending out the guidance voice, and controls the display device 110 to continue displaying the stimulation video, and when the eye movement fixation point is located outside the display area again, the above operations are repeated until the display of the stimulation video is finished.

in step 310, the control device obtains the position information of the eye movement fixation point of the tested person.
Specifically, at the time of screening, the control device acquires position information from the gazing point detection device.
Here, the gaze point detecting device is capable of detecting position information of the gaze point of the eye movement of the person under test based on the pupil-cornea reflection technique, and transmitting the detected position information to the control device.
Specifically, point of regard detection device can be eye tracker, and optionally, this eye tracker is screen eye tracker, compares with wearing formula eye tracker, and screen eye tracker can alleviate the burden of the personnel head that receives, improves the comfort level when the screening by the personnel that receives.
In step 320, the control device determines a first time period based on the location information.
Specifically, the control device can determine the time period that the eye movement fixation point is located in the display area according to the position information of the eye movement fixation point detected by the fixation point detection device, and then, in combination with the time period that the stimulation video is displayed in the display area, the first time period that the tested person watches the stimulation video can be determined.
In the process of determining the first time period according to the position information, in order to enable the tested person to watch the complete stimulation video, the electroencephalogram acquisition device can acquire more electroencephalogram data of the tested person when watching the stimulation video, when the eye movement fixation point is determined to be located outside the display area, the control device is further used for controlling the display device to pause displaying the stimulation video, and when the eye movement fixation point returns to the display area again, the control device is further used for controlling the display device to continue displaying the stimulation video.
Further, when the eye movement fixation point is located outside the display area, in order to enable the attention of the tested person to return to the display area as soon as possible (the eye movement fixation point is located inside the display area), the screening efficiency is improved, and the control device is further used for guiding and reminding the tested person so as to guide the tested person to watch the display area.
For example, the control device is configured to control the display device to display a guidance video in the display area so that the person to be tested looks at the display area.

Specifically, control device can be extracted from all brain electrical data that brain electrical detection device gathered according to the first time quantum with the brain electrical data (being first brain electrical data) that the personnel that receive watch amazing video after receiving the brain electrical data that brain electrical acquisition device gathered to whether confirm according to first brain electrical data that whether the personnel that receive exist social disorder. The method for determining whether the tested person has social disorder or not by the control device according to the first electroencephalogram data is not limited at all.
Alternatively, whether the tested person has social barrier or not can be determined according to a preset logic algorithm.
Alternatively, whether the tested person has social barrier can be determined by a pre-trained machine learning model.
Optionally, whether the tested person has social obstacles or not can be determined by comparing the first electroencephalogram data with preset electroencephalogram data.
Specifically, the preset electroencephalogram data are electroencephalogram data which are stored in a control device in advance and are matched with the physiological age and the psychological age of a tested person when a normal person watches a stimulation video, if the deviation between an electroencephalogram index (such as the latency of N170, the amplitude of beta wave oscillation and the like) extracted from the first electroencephalogram data and a corresponding electroencephalogram index extracted from the preset electroencephalogram data is too large (the deviation exceeds the preset value), it is indicated that the tested person has social disorder, and if the electroencephalogram index extracted from the first electroencephalogram data is basically the same as the corresponding electroencephalogram index extracted from the preset electroencephalogram data (the deviation is smaller than or equal to the preset value), it is indicated that the tested person does not have social disorder.
