Lecture Outline• Definition• Multimedia Building Block• Types of Multimedia Presentation• Multimedia in software• Delivery of Multimedia• Applications of Multimedia


What is Multimedia

• Multimedia = Multi + media• Multi = many• Media = medium or means by which

information is stored, transmitted, presented or perceived.


What is Multimedia

• By simple definition: Multimedia can be any combination of text, graphics, sound, animation and video, to effectively communicate ideas to users.


What is Multimedia : Definition 1

“Multimedia is any combination of text, graphic art, sound, animation and video delivered to you by computer or other electronic means.”

Multimedia: Concepts & practice


Multimedia Building Block

• Text• Image• Sound• Animation• Video


Types of Multimedia Presentation

• Linear Multimedia– Users have very little control over the presentation

• Interactive Multimedia– Users dictate the flow of delivery.


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


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.


Fun = Greater Efficiency

• Multimedia enhanced software is fun to use• Increase user’s efficiency in completing /

achieving the task’s goal.


Delivery of Multimedia• Online

Downloadable over the network.+ Offers live/real time multimedia content+ Easy retrieval of updated information- restricted by bandwidth and connection speed

• Offline CD-ROM / DVD+ Portable- users need to buy the product new version for updates.


Applications of Multimedia

• Business• Education• Entertainment• Medical• Public places• Etc…


Business• Presentation • Training

– Simulation– Animation

• Marketing / advertisement• Audio Video conferencing / teleconferencing• E-commerce

– Virtual store


Education

• Training– Simulation – Animation

• Courseware• Information archive / electronic book


Entertainment

• Games• Movie / video on demand• 3D cartoon animation• Visual effect / sound effect• Virtual reality


Medical

• Telemedicine• Virtual surgery • Micro surgery• MRI

– Magnetic resonance imaging (MRI) is an imaging technique used primarily in medical settings to produce high quality images of the inside of the human body.


Public places

• Information kiosk• Electronic billboard


Etc…

• Forensic multimedia• Visualisation

– is where graphics and animation are used as a mean of presenting complex data.


Terminologies…

• Multimedia presentation / product is created by multimedia developer.

• The shipped or delivered product is a multimedia title.

• Developers create multimedia content using authoring tools.
