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.

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.

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

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

Linear Vs Nonlinear

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.

Creating and Delivering Multimedia Graphic User Interface - GUI

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

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

Types of Multimedia Interactive multimedia Hyperactive multimedia Linear multimedia

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

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

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)

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

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

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

Delivering and Using Multimedia Multimedia demands bandwidth CD-ROMs hold 650-700 MB (80 minutes of full screen video) DVD-ROMs hold 4.7-18 GB Multimedia can be delivered on line

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

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

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

Delivering and Using Multimedia Virtual Reality
