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
Bina Nusantara
Structural Issues
• Depth
• Breadth
Bina Nusantara
Navigation
• Key Questions– Where am I?– Where have I been?– Where can I go to?
• Navigation Techniques– Browsing– Searching– Site Maps– Indexes
Bina Nusantara
Navigation
• Providing indicators - ‘you are here’– Cascading menus– Thumbnail maps– Color coding
• Providing ‘Search facilities’– Sitemaps– Explicit ‘Home’ button
Bina Nusantara
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

Screen Resolutions
2006 Statistic 2001 Statistic640x480 : 5.3 %
800x600 : 13.2 %
1024x768 : 44.4 %
1152x864 : 5.2 %
1280x1024 : 31.9 %From Screen-Resolution.com
640x480 : 5.7 %
800x600 : 52.5 %
1024x768 : 32.7 %
1152x864 : 2.3 %
1280x1024 : 2.9 %From statmarket.com
• 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

Bina Nusantara
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
