Design And Development Of Service System Based On Child Emotional Data

With the improvement of residents'living standards,early childhood education has received more and more attention from the public.However,the problems exposed today are deeply worried,and some even touch the bottom line of child safety.Most kindergartens ease parental concerns by providing parents with real-time surveillance videos,but this practices both violate the privacy of students and teachers and take up a lot of time of parents.This topic takes children's emotions as the starting point,and uses Microsoft's face recognition and emotion recognition algorithms to display the monitored children's emotions to parents' parents through statistical calculations.On the one hand,it solves parents'concerns about child safety;on the other hand,it explores the relationship between children's emotions and the quality of children's learning and interest,helping parents to explore the talents of young children.In the system design,combining the needs of parents and the actual needs of service system development,while providing services to parents and ensuring the quality of services,divide the system into application for parents and supporting client.The application for parents is divided into four functional modules:growth,security,analysis,and personal center.The growth module supports parent users to view the daily learning of the child,including the emotional performance of each class;the security module supports the parent users to view the child's daily emotional state,providing parents with low-alert warnings and viewing the child's laughing moments;The analysis module provides the parent user with service to view the child interest analysis and the child ability analysis based on the emotion calculation;the personal center module supports the feedback of the parent user,fills in the questionnaire,and modifies the data.The support side is divided into four functional modules:data annotation,monitoring operation and maintenance,buried point statistics and questionnaire survey to ensure data accuracy,service system stability and feedback from users.The data annotation module supports the annotation of the child face data;the monitoring operation and maintenance module supports viewing the running status of the camera and the script,and provides an alarm function;the buried point statistics module displays the user browsing data of the application end,laying the foundation for subsequent version iteration;the questionnaire module supports the function of creating questionnaires,publishing questionnaires,statistical results,etc.,and can publish questionnaires on the application side to check the satisfaction of parents on the analysis results of this system.In the system implementation,the application side adopts the technical framework of React+PHP+MySQL,and the support side adopts the technical framework of Jquery+PHP+MySQL to complete the development of the whole system.
