Multimedia, Interactivity, and
New Media Defined - Multimedia
•
A medium is a way of conveying information. Speech is
one medium, text is another.
•
There are many kinds of unique media. ("Media" is the
plural of "medium.")
•
Multimedia is the use of more than one type of medium
at the same time to convey a message or information.
A lecture presented along with slides is an example of a
simple multimedia event.
Multimedia, Interactivity, and
New Media Defined - Interactivity
•
Like television, a PC can present many media types
simultaneously. For example, text, animation, music,
and narration can all play at one time.
•
TV is not interactive; it only delivers content. The PC
enables the use of interactive multimedia such as
games and reference products.
•
Interactivity means that the user and program
respond to one another. The program provides an
ever-changing array of choices, which the user selects
to direct the flow of the program.
Multimedia, Interactivity, and New Media
Defined - New Media and Digital Convergence
• "New media" is a term that encompasses all types of
interactive multimedia technologies.
•
New media bring together not only multimedia content,
but delivery technologies such as cable, telephone lines,
networks, and the Internet.
•
New media is based on the concept of digital
convergence, which means many different technologies
can be used together to deliver different types of
content in one digital stream.
Information in Layers and Dimensions
•
The Importance of Content
•
Hypermedia and Navigation
Information in Layers and Dimensions The Importance of Content
• The purpose of multimedia is to make information
(content) more interesting, compelling, or enjoyable, as
well as easy to navigate.
• Multimedia technologies give users choices of the type
of content that is presented, and the manner in which it
is presented.
• Regardless of the technologies used in multimedia, the
primary focus is on providing high-quality content.
Information in Layers and Dimensions Hypermedia and Navigation
• The process of moving through electronic information is
called navigation.
• Well designed multimedia products provide a variety of
methods for the user to navigate and choose content.
Multimedia navigation is based on “hypermedia”.
• Hypermedia allows different types of content to be
linked together. By choosing a hyperlink, WWW users
jump to a new web page or multimedia feature.

Hardware Considerations for Multimedia
•
Most new PCs are multimedia-capable, featuring all the
hardware required to play back multimedia content.
•
To play multimedia content, a PC needs (at the very
least) a sound card, speakers, and a CD-ROM or
DVD-ROM drive. A large hard disk and lots of RAM
are also helpful.
•
New PCs must meet requirements set in the PC 97 or
PC 99 standard to be considered multimedia-compliant.
Applications for Multimedia
•
In the School
•
In the Workplace
•
In the Home
Applications for Multimedia - In the School
•
Many types of multimedia tools are being used in
schools, from CD-based reference products, to games,
to online collaboration.
•
Distance learning technologies allow schools to provide
courses online, over the Internet. These online learning
environments are called virtual universities.
Applications for Multimedia –
In the Workplace
•
Companies are increasingly using multimedia for sales,
marketing, and training.
•
Using computer-based training (CBT) products,
companies can quickly and cost-effectively teach
employees new skills.
•
Because multimedia content can be distributed over the
Web, many companies have developed online outlets
which enable customers to view and purchase products
from their PC.
Applications for Multimedia In the Home
In the home, multimedia products are used largely for
the following purposes:
•
Reference materials
•
Self-help and instruction
•
Entertainment
