Research On The Application Of Multimedia Teaching Based On Kinect Gesture Recognition

With the development of computer technology,the interaction between man and computer is becoming more and more frequent,people are increasingly pursue more human,simple and friendly way of human-computer interaction.Human-computer interaction(HCI) from the traditional manual operation interface,the command line interface,graphical user interface,development to deeply favored by natural user interface(NUI).Natural user interface is the user with the most natural way of communication,such as language and gestures,etc.) to interact with the computer,more in line with the natural behavior of people.The gestures as a kind of natural man-machine interface,can provide human and computer interaction with more natural and more intuitive approach.As a revolutionary product of human-computer interaction technology,called somatosensory devices,the depth of information and bone data,by identifying gestures,voice,etc way to understand the operator’s intentions,the concept of human-computer interaction more thoroughly,therefore is called "landmark of human-computer interaction.This article will access gesture recognition technology and the multimedia teaching,the combination of the first to access it analyzed the status quo of the application research in the field of education,for the sample quantity,content and application of case analysis,it is not hard to find,apply it to research more and more widely in the field of education.The device body feeling technology is studied the structure,working principle and development course,etc.Again for gesture recognition methods and gesture recognition method based on it were studied.The design and implementation of the teaching system is based on the device,the device combined with PowerPoint,begins with gesture to the operation of the PPT.The significance of this study is to use it as a teaching aid,improve the user experience of teaching teacher,promote learners more active learning.In multimedia teaching,teachers need to constantly moving to the click of a mouse,keyboard or by certain handheld devices effectively for the computer to control.At the same time in a lot of classroom teaching organization form,mainly by teachers as the main body,the students are passive listening.When the students just listen to below,less its interaction with the teacher.Based on the development and application of device is using motion-sensing technology,to obtain the depth information of the human body,through the gesture recognition to understand the operator’s intentions,so that the teaching of computer operation more convenient and quick.Teachers directly to students at the same time,more relaxed,in class teaching is more flexible,more closely upon interaction between teachers and students.At the completion of this study is based on the device,on the basis of gesture recognition,further realize natural user interfaces,build body feeling teaching environment,improving the teaching of appeal.
