Why Design?
“People need to get into your software in about
20 seconds and get immediate possitive
feedback and reward; then they are smiling and
having a good time and they want to go further.”
– Trip Hawkins, Electronic Arts Chairman.

Information Architecture
• Linear / Sequential  telling a story
• Hierarchical  organized information
• Network / Web  exploring

Structural Issues
• Depth
• Breadth

Usability Attributes
•
•
•
•
•
•
•
Match between system and the real world
User control and freedom  support undo and redo
Consistency and standards  “exit” or “quit” ?
Error prevention
Flexibility and efficiency of use  expert/basic mode
Aesthetic and minimalist design
Help users recognize, diagnose, and recover from
errors  understandable error message
From Jacob Nielsen’s “Ten Usability Heuristics”

Interface Design Issues

Hyperlinks, icons, and buttons
Alignment
Text
Color
Screen size and resolutions
And so on .…
Bina Nusantara
Hyperlinks, Icons, and Buttons
• Use common colour to indicate the state of hyperlinks
(selected, rollover, or clicked)
• Provide icons/buttons that make sense
• Do not force user to learn many new/special icons
• How the buttons is activated/selected  highlight or
shape change
Bina Nusantara
Alignment
• Both ‘horizontal’ and ‘vertical’ elements on the page.
• Good alignment contributes to cleaner communication
• Centered text is visually unsophisticated and increases
reading time
• Uniformity of alignment of elements throughout the
website
Bina Nusantara
Text
•
•
•
•
Takes longer to read off a screen than from a book
Consider hierarchy of information
Present key information first
Writing - direct, concise, short paragraphs and bulleted
lists
• Limit use of typefaces - maximum 2
• Sans-serif faces are more readable
Bina Nusantara
Color
• Use simple combinations  color theory
• Warm colors look larger than cool colors
• Bright colors larger than dark ones.
• Intense, saturated color can cause eye strain when used
in quantity so don’t use it as background

• Resolution is increasing
• Design for lowest and most used resolution for
ensured success
Bina Nusantara
Interface Design Pointers
• Define a control area and a stage area
• Choose muted background images and appropriate
button graphics
• Use visual depth to indicate importance
• KISS
Bina Nusantara
Metaphor
• A complex application can be understood more easily if
the user interface is depicted in a way that resembles
some commonplace system
• Appropriate metaphor allow user to learn/remember
minimal rules or procedures of the application
Bina Nusantara
Metaphor Example – ReadPlease 2000

Metaphor Example – PowerDVD = Tape Deck
Bina Nusantara
Metaphor Issues
•
•
•
•
Used for an application not one button
Several metaphors in one application
Metaphor isn’t always necessary
Stick to metaphors that will be understood by most
users
• Some metaphors don't cross cultural boundaries
