Types of Multimedia Presentation
• Linear Multimedia– Users have very little control over the presentation
• Interactive Multimedia– Users dictate the flow of delivery.
![Page 9: Lect 01 UnderstandingMM](https://reader034.vdocuments.site/reader034/viewer/2022051502/577cc9e51a28aba711a4e47f/html5/thumbnails/9.jpg)
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.

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
