is a basic sketch that shows the rough placement of
media elements. You should be able to draw a storyboard
for a given situation: Example: draw a storyboard for a
multimedia application for a golf club. The sketch should
include the company name, navigation buttons, the club
logo and play the sound of someone teeing off.

structures shown.

32

Identify and explain the type of
navigational structure shown here.

33

Linear Navigation

 Like a PowerPoint presentation where you go
through the screens in order, one after the other
 The presentation will let you go forward or back, but
you can’t view it in just any order that you like.
 This presentation uses linear navigation.

34

Types of music

Classical Rock Jazz

Beethoven Mozart

35

Hierarchical Navigation
 Has a structure where you
have a main screen with
Types of music

links on it to sub sections.

Classical Rock Jazz

Beethoven Mozart

36

structure that would be best for:
1) Ensuring that a user moves through the
application in a set order so they don’t miss
anything
2) Letting a user move from one screen to any
other in any order they like
3) Giving a selection of main topics and then
the user can browse the sub-section of a
main topic

39

43

Explain why a multimedia
application would use
transitions between screens.

44

Types of Interface
 An interface is a window or screen that allows the
user to interact with the computer (Human-
computer interface, HCI).
 The best type of interface should be selected
during the design stage.
 The main types of interfaces are:
 Command line
 Menu-driven
 Form fill-in
 GUI
 On the next screens, you will be asked to
identify and explain the types of interface.
45

interface shown in this example.

46

Command Line: You must type
in commands:
 Advantages of CLI
 Good for experienced user,
can enter commands
quickly
 Does not require fast
processor.
 Disadvantages of CLI
 Command language difficult
to learn
 Needs experienced user.

47


48

Menu driven interface:
 Does not feature many
pictures
 Limits selections to list
boxes, buttons to click
on
 Reduces errors

 Does not require
keyboard skills

Main Menu

54

Graphical User Interface (GUI)
 Uses pictures mainly
 Limits need for reading; so good for children
 Fast, but needs a good computer processor
 Takes up a lot of memory.
 Encourages exploration as users find it more interesting
to look at

resolution reduces the file size
of the image.
