Mobile App Design Navigation Patterns & Information Architecture 2 — Questions and Answers
Question 1: What is 'progressive disclosure' in mobile navigation design?
- Revealing all app features to users immediately upon first launch
- Gradually revealing more complex features as the user needs them (Correct answer)
- Hiding all navigation elements until a user completes login
- Showing a loading animation before displaying any content
Correct answer: Gradually revealing more complex features as the user needs them
Progressive disclosure presents only the most essential information initially and reveals additional details or features as the user engages more deeply with the app.
Question 2: Which navigation type is best for content with a natural hierarchy, such as an email client (inbox → thread → reply)?
- Flat navigation
- Hub and spoke navigation
- Hierarchical navigation (Correct answer)
- Tab bar navigation
Correct answer: Hierarchical navigation
Hierarchical navigation lets users drill down through content levels, mirroring the natural organization of structured content like email or file systems.
Question 3: What is a 'bottom sheet' in mobile UI design?
- A navigation bar permanently fixed at the bottom of the screen
- A panel that slides up from the bottom to provide contextual options or content (Correct answer)
- A footer area containing legal disclaimers and links
- A scrollable list of items anchored to the bottom of a page
Correct answer: A panel that slides up from the bottom to provide contextual options or content
A bottom sheet is a UI component that slides up from the bottom of the screen to display contextual actions, additional content, or options without navigating away from the current screen.
Question 4: According to Apple's Human Interface Guidelines, what is the recommended minimum touch target size?
- 24×24 points
- 44×44 points (Correct answer)
- 32×32 points
- 56×56 points
Correct answer: 44×44 points
Apple's HIG recommends a minimum touch target size of 44×44 points to ensure users can accurately tap interactive elements and reduce input errors.
Question 5: What is 'deep linking' in mobile app navigation?
- Linking only to the deepest level of the app's content hierarchy
- A URI that navigates users directly to a specific screen within an app (Correct answer)
- Navigation that requires multiple levels of user authentication
- A technique for embedding hyperlinks within long-form article content
Correct answer: A URI that navigates users directly to a specific screen within an app
Deep linking uses URIs to route users directly to a specific location within a mobile app, bypassing the home screen and landing on targeted content.
Question 6: What does 'hub and spoke' navigation mean in mobile app design?
- Navigation with multiple parallel paths that never intersect
- A central home screen from which users navigate to features and return (Correct answer)
- A circular navigation pattern where each screen links to the next in a loop
- Navigation elements arranged in a visually circular spoke-wheel layout
Correct answer: A central home screen from which users navigate to features and return
Hub and spoke navigation uses a central hub (typically a home screen) from which users access various features (spokes) and must return to the hub to navigate to another section.
Question 7: Which navigation interaction is associated with going back on Android gesture navigation?
- Pinch-to-zoom gesture on the current screen
- Double-tap on the top of the screen
- Swipe inward from the left or right edge of the screen (Correct answer)
- Long press on any empty area of the screen
Correct answer: Swipe inward from the left or right edge of the screen
On Android with gesture navigation enabled, users go back by swiping inward from the left or right edge of the screen, replacing the traditional back button.
