Now days the internet is the main source from where the students can be able to gathers the desired information and knowledge on relevant parts of their courses. They took out the notes, presentations, slides, lessons and study materials in various form so that they can read and study them in their mean time also.
This Web based system helps in enhancing the standard of education. Students can benefit a lot from the availability of means to review and repeat lecture material with the pace and at the time that is best suited for them. Therefore the effectiveness and convenience of classroom lectures can be dramatically increased.
That's why we need modernized tools and equipment's to capture that whole session so that they can be reviewed later accordingly. These multimedia tools are of very high cost and available only on competitive range so that not everyone can buy/use them in there daily life. It is not surprising that deployment of such systems is very limited and that most lecture materials in the Internet are still only available as a series of lecture slides, therefore missing any additional information like speech or graphical annotations.
