UI DESIGNUsability Principles
Tuesday, 22 April, 14
LEARNABILITY- Predictability
- Users expect result of action- based on past experience- e.g. Use Mouse to drag Label / Panel
- Synthesizability- Users access result of action based on display- e.g. “Refresh” after each modification
- Consistency- Consistent Button / Font Size

FLEXIBILITY- Dialogue initiative
- User Preemptive Dialogue- e.g. Click Button
- Customizability- Ability of user to modify interface- e.g. Change Font Style and Size in the drawing
