Types of Multimedia Presentation
• Linear Multimedia– Users have very little control over the presentation
• Interactive Multimedia– Users dictate the flow of delivery.
CMPD273 Multimedia SystemPrepared by Nazrita Ibrahim © UNITEN2002
Linear Multimedia– The users sit back and watches the
presentation– The presentation normally plays from the
start to end or even loops continually to present the information.
– A movie is a common type of linear multimedia

Interactive Multimedia
– The users control the delivery of elements – to control the what and when.
– Users have the ability to move around or follow different path through the information presentation.
– Advantage: complex domain of information can be presented.
– Disadvantage: users might lost in the massive “information highway”.
– Useful for: information archive (encyclopedia), education, training and entertainment.

Why integrate multimedia in software?
• Ease of use• Self-Paced Interaction and Better Retention• Better understanding of the content• Cost effective• Fun = Greater Efficiency
CMPD273 Multimedia SystemPrepared by Nazrita Ibrahim © UNITEN2002
Ease of use• Through Graphical User Interface (GUI) • Intuitive + easy to use Increase productivity

Self-paced interaction, better retention
• Self-paced learning of information– Ability to process information at one’s own pace
• Better knowledge / information retention

Better understanding
• Multimedia can be used to illustrate complex information in an easier way.
• Concurrent presentation of text, images, animation, video and sound complement each other to provide richer and broader range of information

Cost effective
• No need for in-depth training manual• Less technical support cost• If the users enjoy the software, they are more
likely to upgrade to the next versions or purchase more product from that company.
