The Research And System Implementation Of Electronic Blackboard Using Electronic Teaching Resources

With the rapid development of electronic display equipment and computer technology,blackboards and projection equipment used in teaching places are gradually replaced by new electronic equipment such as touch interactive teaching equipment.At present,in the classroom teaching process,teachers mainly use electronic devices to display electronic teaching resources such as documents and videos.From the perspective of the application of e-learning resources in the classroom,teachers need to spend a long time to prepare teaching courseware in the course of lesson preparation,and electronic resources such as documents and videos require specific software to open,display and annotate.In view of the existing problems in the use of electronic teaching resources in the classroom teaching process,this paper conducts research and analysis and proposes a method suitable for the use of electronic teaching resources in the current classroom teaching environment.The design idea of this research method is to use a unified operation Open and exit different types of e-learning resources by designing corresponding modules to achieve the display of different types of e-learning resources.At the same time,it can directly annotate e-learning resources in the display state to meet classroom teaching needs and improve teaching efficiency.The content of the research mainly focuses on the following aspects.In terms of document opening,after selecting Word,Pdf,and PPT documents according to the file directory,the contents of these three types of document processing are displayed.In terms of document display,two common document display methods,Word and PDF,are transformed into a form similar to PPT screening and display.For video display,the video playback technology in WPF(Windows Presentation Foundation)is used to load and display video files in different formats.For the projection display of the booth,it can directly call the camera of the booth to display the physical information.For the annotation of e-learning resources,you can directly write comments on the e-learning resources in the display state.This article first analyzes the research background and research status of the above methods,introduces the related technologies used in the system development process,determines the basic requirements of the system design,then proposes the system function design plan,and finally implements the specific implementation of the system With functional testing.The realization of the system has great application potential for the use of electronic teaching resources in the teaching process,and has certain commercial value and development prospects.
