  graphic art, sound, animation video
  Electronically delivered with effective
  communication interactivity

Above 5 Elements Computer based medium

1.1 Elements of Multimedia

• Text
• Sound / Audio
• Graphics / Pictures
• Video
• Animation

4
1.2 Key Components of Multimedia

• A computer based medium
• Fundamental to the development and delivery of
  multimedia is a computer capable of incorporating
  various elements, such as sound and animation,
  and providing an environment in which the user
  can interact with the programme.
• Interactivity
• The ability of the user to interact with the
  program
• Request made information provided
• Effective communication
• Burger (1994) stated
• Effective communication is the most important
  criteria in Multimedia.

1.3 Extensive use of Multimedia

• When to use Multimedia?
• Connecting human to electronic information
• Non-extensive text information is used
• Non-liner information presentation
• Retrieving precise and selective information
• (Hypermedia)
• Gaining and holding attention and interest
• To improve information retention
• Providing information through entertainment

6
1.3 Extensive use of Multimedia

• Why to use Multimedia?
• Humans are multimedia communicators
• Human brain is created to respond to visual and
  audio stimulus
• The most powerful way to deliver information is
  with visual and audio combination
• Multimedia can help to clarify difficult concepts
  and better transfer information to users

7
1.3 Extensive use of Multimedia

• Why to use Multimedia?
• According to Dr. Albert Mehrabian, a specialist
  in interpersonal communication at the University
  of California, says
• People recall 20 of what they see
• 40 of what they see hear
• 70 of what they see, hear do
• Multimedia allows for seeing, hearing and doing

  also

12
1.3 Extensive use of Multimedia

  print and refer to their own convenience

13
1.3 Extensive use of Multimedia

• 4.5 Virtual Reality
• Extension of Multimedia
• Technology Creative Invention VR
• Electronic goggles, helmets, special gloves and
  bizarre human interfaces to make u feel inside a
  lifelike experience
• 3D graphics animation plays the important role
  here to achieve the real feel

14
1.4 Your Target Audience

• Know Your Audience
• Identify the users who will be using the system
• Who the audience are?
• What is the message or information to be
  delivered?
• What platform the product is to be delivered on?
• How will it be distributed?

15
1.4 Your Target Audience

• Audience analysis
• Who?
• Demographic description
• Age
• Gender
• Children or Men
• Location
• Social Status
• Religious beliefs
• Personal View on how your audience will react
• Viewing Environment
• Level of Education
• Background knowledge or assumed prerequisites
• Technological skill level
• Their attitudes towards system content
• Special needs

16
2.0 Storyboarding
17
2.1 What is a Storyboard?

• Sequentially laying out in pictorial form
  everything that happens during each successive
  moment of a show
• A presentation without a storyboard is like a
  cart without a horse. You have no idea which
  direction whomsoever is going to pull the cart.
  And when you realize your mistake, it may be too
  late. And it is at this point that our
  storyboarding story unfolds
• What exactly is a storyboard? Is it a piece of
  paper or a part of your computer screen? Is it
  that part of your mind where you store the
  sequence of your creativity? Actually, its all of
  them - the 'storyboard' is both abstract and
  physical - in our thoughts and on paper.
• The abstract storyboard has got more to do with
  our imagination and visualization - it is also
  the source, inspiration and the very existence
  that channels the physical storyboard.

A Simple template

3.0 Text

• Text was born 6,000 years ago
• Ancient people scraped on mud tablets and dried
  in the sun
• Sculptures were signs symbols deemed to be
  text, expressing a meaning
• Modern culture skills were reading writing
• Today text delivers information with potential
  meaning!

20
3.1 The Power of Meaning

• Single word may cover many meaning widely
  understood by vast number of people
• Words symbols are the most common way of
  communicating accurately in detail
• Fortunately they become the vital elements of
  multimedia menus, navigation systems content

21
4.0 Audio

• Audio sensuous element of multimedia
• Use of sound makes you feel heaven or hell
• Something vibrates in the air by moving back and
  forth, creating wave ripples of pressure,
  stimulating the ear drum is sound
• Can be speech, music or plain noise or song etc.,

22
5.0 Graphics

• Any diagrams, drawings, and other non-textual
  material that is computer generated and displayed
  on a video screen or monitor
• Graphics express more than words

23
6.0 Animation

• Animation adds visual impact to your multimedia
  project
• Plays a huge role in entertainment and education
• Very hard to show few things in real where
  animations can really help it like blood flow
  through the veins from the heart to other parts
  of the human body or working of a car engine

24
6.1 Principles

• Television video builds 30 fps to develop smooth
  movement
• Computer builds 12 to 15 fps
• When the image are progressively and rapidly
  changed, the arrow of the compass is perceived to
  be spinning

25
6.2 Types of Animation - Cell
2 types of animation
2D 3D
2D Cell Animation Path Animation
3D Morphing Warping Kinematics
26
6.2.1 Types of Animation - Path
27
6.2.2 Types of Animation - Morph
28
6.2.3 Types of Animation
29
6.2.4 Kinematics

• the study of the movement and motion of
  structures that have joints, such as a walking
  man
• animating a walking step, you need to calculate
  the position, rotation, velocity and acceleration
  of all joints and articulated parts like knees
  bend, hips flex, shoulders swing and the head
  bobs
• Poser 3D modeling software has pre-assembled
  human models in many poses
• Smaller the object, lesser the space it occupies
  and faster it can move.

30
7.0 Video

• Graphics, animations are picturesque information
• Video shows realism
• Brings closer to real world
• Carefully planned, well-executed video clip can
  make a dramatic difference
• Essential to know about this medium, its
  limitations and its costs

31
8.0 What is Ergonomics?

• Ergonomics is the ability to adapt human to a
  machine environment.
• The study of the physical characteristics of the
  interaction.
• Expressing users requirement to the system.
• System grants variety of solution for user to
  choose.

Reference Human-Computer Interaction by Alan
Dix, Janet Finlay, Gregory Abowd, Russell Beale
32
8.1 Issues addressed by Ergonomics

• 2.1 Arrangement of Controls and
• Displays
• 2.2 The physical environment of the
• interaction
• 2.3 Health issues
• 2.4 The use of color
• 2.5 Ergonomics and HCI (Human Computer
  Interaction)

33
9.0 Managing Change to reduce cost

• Multimedia and cost reduction containing costs.
• There are three ways for containing costs
• Downsizing
• Outsourcing
• Business Process Re-engineering

34
10.0 Assembling Delivering Your Project
35
10.1 Assembling Testing

• Organize all the elements necessary for Delivery
• Check up for dead links
• Check for unloaded pictures
• Check for bugs in the program
• Check for unexpected delays in displaying the
  information
• After assembling, run a trial to conduct a
  overall inspection of the program integrity

36
10.2 Testing

• Alpha Testing
• Beta
• Testing the prototype
• Bug report form
• Rectify the bug or change according to Users
  specification

37
10.3 Delivery

• Attaching Installation programs for proper setup
  documentation
• Make sure it is done for a hybrid platform
• Specification should be listed for setup or usage
  of program
• Choose the delivery mode as specified by the user
  (Web or CD)
