Development And Application Of Portable Heart Rate Information Monitoring System Based On Bracelet

In recent years,the research of teaching behavior has become the focus in the field of teaching research.But in the current teaching theory,the study of teaching behavior ignores the behavior of students,and pays much attention to the study of teacher's teaching behavior and teacher-student interaction behavior.Students are the main body of educational significance and teaching effects,so paying attention to students ' behavior is an key direction of teaching research.The continuous development of educational informatization and the gradual rise of wearable devices have opened up a new way for the research of educational teaching.At present,the use of intelligent equipment to monitor human physiological information in the field of education and teaching has become more and more widespread.Based on the study of Learning behavior and physiological information,we not only study the key problems of the behavior analysis and the development process of heart rate information monitoring system by literature analysis,video recording,contrastive analysis and software engineering but also design and implement a portable heart rate information monitoring system,and apply the system for experimental analysis.The main research work of this paper includes the following three aspects:(1)Combining Bluetooth and optical sensor smart bracelet,we develop the smart bracelet for second time.The Android application is developed to communicate with the smart bracelet via Bluetooth,and to achieve the data transmission to the cloud platform to complete getting the student heart rate data in real-time.(2)Video observation experiment.We use video equipment in the classroom to observe and collect the heart rate data from the selected subjects.(3)Application and analysis of heart rate information monitoring system.Through the data collected in the experiment,and repeated observation of the video content to do the corresponding behavior coding and data processing.Based on the research objective,the differences of heart rate information between different learning behaviors and students ' behavior were analyzed.To sum up,the thesis unifies the research goal,For the two development of the function module of the bracelet interface,data transmission is realized by Bluetooth.Applying wireless physiological signal acquisition system to the classroom process provides a new perspective for teachers to understand the real state of students,which is of great significance to the classroom teaching and the study of students,and is of definite innovation and practicability.
