2. UID
• Proper interface design begins with careful
analysis of the user.
• Proper analysis of task
• Proper analysis of Environment.
• Prototyping is a common approach to user
interface design.

3. Place User in Control
• Don’t force the user to perform unnecessary actions or
undesired actions.
• Hide technical internals from the user.
• Design for direct interaction.
• Allow the reversible process.
• Provide flexile interactions.

4. Reduce User Memory Load
• Reduce demands on Short Term Memory
• Establish meaningful defaults.
• Define short cuts
• Create meaningful layout
• Improve progressive fashion (information)

5. Make interface consistent
• Allow user to put the current task into a
meaningful context.
• If past interaction models have created user
expectations, do not make changes unless
there is a good reason to do so.

6. UI Design Models
• Design Model:
architecture, procedural, interface models
• User Model: user profiles, frequent users
interests.
• System Perception: User’s mental image of
system.
• System Image: look and feel images.

7. Interface Design Issues
• System response time
• User help facilities.
• Error information handling

8. UI Evaluation cycle
• Preliminary design
• Build first interface prototype.
• User evaluates interface
• Evaluation studied by designer
• Design modifications made
• Build next prototype.
• If interface is not complete then go to step 3.
