MULTI USER WHITE BOARD Interactive Lecture Archive SYSTEM
Abstract of the Project
 The primary motivation for the creation of the e-learning applications was the facilitation of collaboration of textual contents and images displayed to users from centralized database system. There was a need for a better way for of learning systems to rapidly exchange large amounts of information, ranging from experimental data and results of analyses to organizational and strategic details related to ongoing experiments. The rapid proliferation of the web and web-related applications, as well as the ever-increasing size and international scope of scientific collaborations, has by now clearly demonstrated the value of the web as a common and necessary tool for research. In addition, it has enhanced the dissemination of scientific knowledge to the general public through the publication of online documents and other web-based multimedia media.
Aim
 VIEWING AND INTERACTING WITH THE INTERNET WEB PAGES
 VIEWING AND INTERACTING WITH SOFTWARE
 NOTE TAKING USING INTERACTIVE WHITEBOARD SOFTWARE
 ANNOTATING THIRD PARTY SOFTWARE, WEBSITES AND IMAGES USING DESKTOP TOOLS
 CREATING AND TEACHING A LESSON WITH INTERACTIVE WHITEBOARD SOFTWARE.
Introduction
 These important features distinguish from the historically common approach to lecture archiving based on a video recording of the event which combines views of the speaker and visual support material. Such a video is necessarily a compromise, as a choice has to be made between focusing on the lecturer or support material, or more precisely part of this material to facilitate readability. The camera operator therefore makes the choice for the viewer as to what is of primary interest at any time. This is in marked contrast to a lecture interface in which the speaker and support material are always in view.
 Regardless of advances to the technology, there will always be some inefficiency introduced by the transmission of a video stream rather than a fixed image. In addition, the video stream lacks the slide preview and rapid search/location functionality provided by the indexed static archive mode. As we will discuss below, such indexing could also be exploited for the development of web-based lecture databases and search engines.
Existing System
 IDroo - Online educational multiuser whiteboard
 Draw and write your ideas
Express your mind through images
All drawings are easily editable vector graphics
 Board800
An interactive multi-user (shared) whiteboard application
Use it for tutoring, collaborative live training, brainstorming, prototyping
An online replacement of your paintbrush application
Board 800 is an interactive multi-user (shared) whiteboard application that can be used for teaching, collaborative live training, brainstorming, and more.
Proposed System
 The project development is an effort to explore the usage of the interactive media learning systems of today’s world for archiving of “content-rich” material, which we define to be lectures, seminars, or other events which include audio, video and visual support materials. The work targets a segment of the tasks that must be completed for scientists and others to optimally draw upon the web for transmitting information for training and archival purposes, as well as for keeping colleagues informed of strategic, technical and administrative decisions.
 While the teacher gives the lecture, Sync-O-Matic records the audio and video from a microphone and camera using the RealProducer and ActiveX control. As the lecturer changes slides, Sync-O-Matic records those actions and the timing of each action in internal text files.
 At the end of the presentation, two archived lectures are produced, one suitable for viewing with a standard web browser from DVD-ROM, and another suitable for viewing directly from a web server. The look and feel of the resulting lectures is controlled using XSL specific “style files”. These style files are written in XML with some specific markup included. The result of the publishing process is a directory with several HTML files, text files used to allow random navigation of the lecture, and the media files.
 The media files make up the bulk of the disk usage. An average quality video and high quality audio (160x120 pixels, 24kps video + 16kbps audio) lecture requires about 36 Mbytes per hour of lecture. This relatively small amount of disk storage allows 15-20 hours of lectures to be stored on a single DVD, and a large number on a web server without resorting to exotic storage technology. To watch a web lecture the user can use any popular web browser. The first time the user views a lecture, it may be necessary to download and install the RealPlayer software (the free version is sufficient), although this software is now commonly bundled with most web browsers. JScript is not required but some advanced navigation features are available if it is enabled.
 Although adequate to meet the requirements of a lecturer in a teaching environment as described above, one of the major challenges of the project is to extend the functionality is beyond its original design in order to handle the demands of live lectures and to cope with a number of challenging recording scenarios, such as hand-written transparencies and blackboard material. The various scenarios encountered and the solutions developed.
