Jakob Nielsen's 10 General Principles for Interaction Design

What does the "Visibility of System Status" principle emphasize in user interface design?

• The system should always operate in the background without user interference.

• The system should always keep users informed about what is going on.

• The system should prioritize complex animations.

• The system should avoid giving feedback to users.

A progress bar displayed during a file upload is an example of which principle?

• Aesthetic and minimalist design

• Visibility of system status

• Help and documentation

• Help and documentation

Why is it important for systems to use familiar language and concepts?

• To prevent the user from making errors.

• To ensure the interface matches the user's expectations.

• To make the system look professional.

• To reduce development time.

• Which of the following best illustrates the principle of matching the system to the real world?

• Displaying a "Trash Bin" icon for deleted items.

• Using complex technical jargon for settings.

• Avoiding user feedback during processes.

• Disabling all help options in the system.

The "Undo" and "Redo" options in software are examples of which usability principle?

• User control and freedom

• Flexibility and efficiency of use

• Help users recognize and recover from errors

• Visibility of system status

When users accidentally trigger an action, what feature aligns with the principle of user control and freedom?

• Automatic updates without warning

• A system log without direct user interaction

• A confirmation dialog box with "Cancel" and "Proceed" options

• A hidden menu for undo actions

Why is consistency important in interaction design?

• To make the interface visually appealing.

• To limit user control over the system.

• To allow designers to innovate freely.

• To reduce the learning curve for users.

What violates the principle of consistency and standards?

• Displaying help options in all sections of the system.

• Using different terms for the same action across the system.

• Using a consistent color scheme throughout the interface.

• Following platform conventions for button placement.

Which of the following is a practical application of the "Error Prevention" principle?

• Offering suggestions during a search query.

• Displaying an error message after an action fails.

• Highlighting mandatory fields in a form.

• Visibility of system status

Which design element aligns with the principle of recognition rather than recall?

• A search box with no suggestions.

• A menu displaying commonly used options.

• Requiring users to type commands from memory.

• Removing tooltips to simplify the interface.
