Example 2
mediumList five principles of good user interface design and explain each briefly.
Solution
- 1 Step 1: (1) Consistency — similar actions should look and work the same way throughout. (2) Feedback — the system should respond to every user action (e.g., button changes colour when clicked).
- 2 Step 2: (3) Simplicity — do not overwhelm users with options; show only what is needed. (4) Error prevention — design to prevent mistakes (e.g., greying out invalid options).
- 3 Step 3: (5) Accessibility — usable by people with disabilities (keyboard navigation, screen reader support, sufficient colour contrast).
Answer
Five principles: consistency, feedback, simplicity, error prevention, accessibility.
Good UI design is invisible — users accomplish tasks without thinking about the interface. Bad UI design frustrates users and leads to errors, abandonment, and negative perceptions.
About User Interface
The visual elements and interaction methods through which a user communicates with a computing system — including buttons, menus, text fields, icons, and layout. A well-designed UI follows principles of clarity, consistency, and feedback to make software intuitive and efficient to use.
