Types of Multimedia Presentation Linear Multimedia Users have very little control over the presentation Interactive Multimedia Users dictate the flow of delivery. CMPD273 Multimedia System Prepared 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 CMPD273 Multimedia System Prepared by Nazrita Ibrahim © UNITEN2002

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. CMPD273 Multimedia System Prepared by Nazrita Ibrahim © UNITEN2002

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 System Prepared by Nazrita Ibrahim © UNITEN2002

Ease of use Through Graphical User Interface (GUI) Intuitive + easy to use  Increase productivity CMPD273 Multimedia System Prepared by Nazrita Ibrahim © UNITEN2002

Self-paced interaction, better retention Self-paced learning of information Ability to process information at one’s own pace Better knowledge / information retention CMPD273 Multimedia System Prepared by Nazrita Ibrahim © UNITEN2002

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 CMPD273 Multimedia System Prepared by Nazrita Ibrahim © UNITEN2002

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. CMPD273 Multimedia System Prepared by Nazrita Ibrahim © UNITEN2002

Fun = Greater Efficiency Multimedia enhanced software is fun to use Increase user’s efficiency in completing / achieving the task’s goal. CMPD273 Multimedia System Prepared by Nazrita Ibrahim © UNITEN2002
