What is Multimedia ?What is Multimedia ?
Multimedia = Multi + media• Multi = many• Media = medium or means by which
information is stored, transmitted, presented or perceived.
• By simple definition: Multimedia can be any combination of text, graphics, sound, animation and video, to effectively communicate ideas to users

Definition Of MultimediaDefinition Of Multimedia
“Multimedia is any combination of text, graphic art, sound, animation and video delivered to you by computer or other electronic means.”
Tay Vaughan
Multimedia : Making it work 5th Ed
“Multimedia is the presentation of a (usually interactive) computer application, incorporating media elements such as text, graphics, video, animation and sound on computer.”

Multimedia has a number of distinct and unique features, including:
Based on Edgar Dale (Cone Of Learning), on average, people remember:
10% of what they read,20% of what they hear,30% of what they see, 50% of what they hear and see, multimedia approach
multimedia rich elements, multi-sensory delivery system can facilitate greater retention of new knowledge

Types of Multimedia Presentation Types of Multimedia Presentation
1. Linear Multimedia– Users have little control over the presentation, just 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
2. Interactive Multimedia– Users dictate the flow of delivery, 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.

Multimedia System CharacteristicsMultimedia System Characteristics
1. Multimedia systems must be computer controlled.
2. All multimedia components are integrated.
3. The interface to the final user may permit interactivity.
4. Information must be represented digitally.
![Page 9: Module 6 Part 1 Introduction To Multimedia. Module Objectives At the end of the module, students should be able to: –Understand the fundamental concepts](https://reader030.vdocuments.mx/reader030/viewer/2022032802/56649e005503460f94aea019/html5/thumbnails/9.jpg)
Why Represent Information in Digital Form?Why Represent Information in Digital Form?
• Storage– Digital representation permits the storage of
different information types on the same devices.• Transmission
– Information may also be transmitted over a single digital network.
• Processing– When digitized, all form of information may be
treated by computer programs, for editing, quality improvement, or recognition of the meaning of the information

Multimedia Design ProcessMultimedia Design Process
• Approaching the design– Designers work closely with producers or
clients throughout the process.– The conceptual model between the designers
and the producers/clients must be closely matched.
– The more works put in design help to eliminate tedious and costly alteration at the end of the project.
![Page 17: Module 6 Part 1 Introduction To Multimedia. Module Objectives At the end of the module, students should be able to: –Understand the fundamental concepts](https://reader030.vdocuments.mx/reader030/viewer/2022032802/56649e005503460f94aea019/html5/thumbnails/17.jpg)
• Design Aspects– Interactivity – how does the process work?
Allow users to control the application in a way that works with the content.
– Structure – the flow ( navigation) and content structure of the multimedia application
– Appearance – determine how the screen will look like.

• Designing the interactivity– Implemented in different ways depending
on the product, content and development tools
– Three approaches• Linear• Programmed branching• Hypermedia

• Designing the structure– Consideration on Navigation
–The term navigation means finding your way to certain information.
–Maps the structures and navigation paths as early as possible.

• Designing the structure– Common Navigation structures
–Linear–Hierarchical–Nonlinear–Composite

• Common Navigation structures– Linear: Users navigate
sequentially, from one frame of information to another
– Hierarchical: Users navigate along the branches of a tree structure that is shaped by the natural logic of the content

• Common Navigation structures– Nonlinear: Users
navigate freely through the content of the project, unbound by predetmined routes
– Composite: Users may navigate freely, but are occasionally constrained to linear presentations of movies or date.

• Designing the structure– Consideration on Hot Spot, button and icon
• Hot spot: Areas of the screen that are ‘clickable’.• Button: Provide button feedback whenever
possible– Have a unique ‘pressed’ or ‘clicked’ state– In HTML, feedback is provided by colour changing
• Icon: Avoid forcing users to learn special icons in your project. Try to follow the design convention set by other leading software.

• Designing the Appearance– Usually called the user interface design or the
look and feel design.– The target is to facilitate communication,
provide entertainment, elicit emotion, etc– The graphic design of your multimedia product
is the users first impression. A well design interfaces provide a good match between the user’s task needs, skill level and learning ability and will lead to satisfied and productive users.

• Designing the Appearance– The interface design principle includes issues
on:• The metaphor• Conceptual model• Anticipation• Intuitiveness• Novice/Expert Mode• Feedback• Consistency• Cognitive overload
– Graphical Approaches.

• Storyboarding– A storyboard is a series of
screens, organized sequentially, screen by screen, and each screen is sketched out with design notes and specification before final rendering.
– A storyboard can be developed with simple pencil and paper as well as using software applications.
