The Design And Implement Of Teaching System Based On Hand Gesture Recognition

In recent years,with the development of science and technology,based on the Internet developed by the relevant applications are also mature,many colleges and universities or enterprises with this boom to develop the appropriate application.Existing teaching systems Because the developers can not fully consider the actual needs of various colleges and universities,so there are adaptive problems,at the same time,the existing teaching system failed to fully teaching and the current popular computer vision technology,So the development of the teaching system lack of interaction.Based on the problem of manual teaching and the loopholes in the existing teaching system,the text will study the teaching system fusion gesture recognition,aiming at improving the effective teaching level and enhancing the interactive ability of teaching system.This paper designs a complete program of online examination system for the purpose of improving the teaching quality of colleges and universities,synthesizing face recognition and ADO technology,and realizes the specific online examination system based on face recognition.In order to improve the quality and efficiency of university education,this paper designs a complete set of teaching system for the integration of gesture recognition and Java related technology.First of all,through the repeated investigation of college teachers and students,the demand analysis of the integration of gesture recognition teaching system needs analysis,including overall analysis,user needs analysis,performance requirements and feasibility analysis.Secondly,according to the above-mentioned demand analysis results and the characteristics of the teaching system of the fusion gesture recognition,the overall function module diagram of the system is developed.At the same time,the overall function module diagram is refined according to the characteristics of each task.Thirdly,through the preliminary development of the teaching system to complete the function of the teaching system database corresponding design,the database design process is divided into conceptual design and logical design,according to the results of the database design to develop the corresponding table to store data.Finally,using the Histogram of Oriented Gradient(HOG)and Local Binary Pattern(LBP)and other characteristics of the decision tree to identify the user's gesture,according to the difference between each gesture to determine the gesture of the corresponding operation,the application of OpenCV comes with the function To achieve gesture recognition method,the use of MySQL data storage,and finally combined with Eclipse to achieve the control of the database.
