Unformatted text preview: area that has benefited a lot with the advent of multimedia. There
are many multimedia applications that directly or indirectly contribute to better
education mechanisms. Some of the main applications are described below.
Multimedia books use audio, animation and video to enrich text and still images
used in printed books to provide better understanding of the subject matter covered
in a book. These books also provide a very effective way of searching for specific
facts in a variety of ways such as searching mechanisms for words and phrases and
hypertext and hypermedia techniques. Due to these reasons, several reference
books such as encyclopedias, dictionaries, telephone directories, etc. are now
being published and made available on CD-ROMs, which allow users to access
the information they need quickly. Many journals, magazines and product manuals
are also being published in electronic form so that users can access and print only
those articles/portions in which they are interested.
A further extension of this idea is digital library, which is a repository of large
information in digital form allowing multiple users to search and access
information of their interest from it. Such a library (being virtual nature because it
stores the books only in soft copy form and not physically) can remain open round
the clock allowing users to access information from it at their own convenient
time. Network multimedia can be used to allow users to access the library from
remote locations. With this extended facility, there is no need for a user to physically come to the library for using it. This overcomes the distance and time
limitations of current libraries.
We saw that multimedia applications can present information in a variety of forms
(text, graphics, animation, audio, video) involving the use of more of our senses.
Hence multimedia presentation can be used to better explain a subject matter to
the students because it enhances the comprehension capability of the students. It is
extremely effective in getting across new ideas and concepts. More...
