3. What is Multimedia?
Multimedia is, as described previously, a woven combination of digitally manipulated text, photographs, graphic art, sound, animation, and video elements delivered by computer or electronic means
When you allow an end user—also known as the viewer of a multimedia project—to control what and when the elements are delivered, it is called interactive multimedia.

Video

5. multimedia developers
When you provide a structure of linked elements through which the user can navigate, interactive multi- media becomes hypermedia.
Although the definition of multimedia is a simple one, making it work can be complicated.
Not only do you need to understand how to make each multimedia element stand up and dance, but you also need to know how to use multimedia computer tools and technologies to weave them together. The people who weave multimedia into meaningful tapestries are called multimedia developers.

6. Multimedia takes many forms
Greeting Cards
Conferencing
Movies
Photo albums
Image catalogs

7. multimedia projects ‘Street View Treks’ Google Street View Treks
These are seriously fun journeys that allow users to satisfy their wanderlust without a plane ticket.

8. cont
Your project may also be a page or site on the World Wide Web, where you can weave the elements of multimedia into documents with HTML (Hypertext Markup Language) or DHTML (Dynamic Hypertext Markup Language) or XML (eXtensible Markup Language) and play rich media files created in such programs as Adobe’s Flash, LiveMotion, or Apple’s QuickTime by install- ing plug-ins into a browser application such as Internet Explorer, Safari, Google Chrome, or Firefox. Browsers are software programs or tools for viewing content on the Web

9. Linear Vs Nonlinear

10. Cont
Determining how a user will interact with and navigate through the content of a project requires great attention to the message, the scripting or storyboarding.

12. Creating and Delivering Multimedia
Graphic User Interface - GUI

13. Producing a Multimedia Project
Requires
a) creative skill
b) technology tools
c) organizational and business talent
d) knowledge of ownership and
copyright rules

14. Where Do You Begin? Study each element of Multimedia
Read trade periodicals
Visit web sites

15. Where Do You Begin? Learn tools to create or edit that element
Learn to use texts and fonts effectively
Learn how to make and edit colorful images
Learn how to animate images into movies
Learn how to record and edit sound

16. Types of Multimedia Interactive multimedia Hyperactive multimedia
Linear multimedia

17. Interactive Multimedia
Allows the user to control
what and
when the elements are delivered

18. Hypermedia Interactive Multimedia which
provides a structure of linked elements through which the user
can navigate

19. Multimedia Project
Software vehicle, messages and content presented on a computer or TV screen
Multimedia title - if sold or shipped to users with or without instructions
Web page if on the www and composed of HTML or DHTML ( Dynamic Hypertext Markup Language)

20. Multimedia Project Linear - users watch from beginning to end
Non-linear and interactive - users are given navigational control and can wonder through the content

21. Authoring Tools
Multimedia elements are “sewn” together using tools like Authorware
to provide facilities for creating and editing text and images
have extensions to drive videodisc players and other peripherals
playback the sound and movie elements created with other tools

22. Requirements Multimedia requires:
large amounts of digital memory and network bandwidth;
GUI (“gooey”) - a graphical user interface
CD-Rom or DVD technology for storage
In the future these may be replaced by “connected” fiber, and radio/cellular technology
DVD – Digital Versatile Disc

23. Delivering and Using Multimedia
Multimedia demands bandwidth
CD-ROMs hold MB (80 minutes of full screen video)
DVD-ROMs hold GB
Multimedia can be delivered on line

24. Why Multimedia? Multimedia enhances learning, memory and retention
audio stimulation - 20% retention rate
audio/visual - up to 30% retention rate
interactive multimedia - up to 60% retention rate

25. Delivering and Using Multimedia
Online uses include:
Books and Magazines
Movies
News and Weather
Education
Maps
Entertainment

26. Appropriate uses Business Schools Homes Public Places
1995 Al Gore - White House Challenge to connect every classroom, clinic, hospital to Information Superhighway by 2000

27. Delivering and Using Multimedia
Virtual Reality

28. New Technologies VR- Virtual Reality
Goggles, helmets, gloves, etc. place users “inside” a life-like experience
View changes as user moves forward, left/right, etc.
Composed of thousands of geometric to be realistic
Will require new standards (VRML) for transmitting virtual worlds on the web
