User Experience Design User Experience Design Interaction Design & Prototyping 1 — Questions and Answers
Question 1: Which type of prototype is best suited for early-stage concept validation when speed matters more than visual fidelity?
- High-fidelity HTML prototype
- Paper prototype (Correct answer)
- Coded interactive prototype
- Pixel-perfect mockup
Correct answer: Paper prototype
Paper prototypes are low-cost, quick to create, and ideal for early concept validation before investing in digital tools.
Question 2: In interaction design, what does the term 'affordance' mean?
- The cost of designing a feature
- A visual cue that suggests how an object can be used (Correct answer)
- The time required to complete a task
- The number of steps in a user flow
Correct answer: A visual cue that suggests how an object can be used
An affordance is a property or visual cue of an object that signals to the user how it can be interacted with, such as a button that appears pressable.
Question 3: What is the primary purpose of a clickable wireframe prototype?
- To test server performance under load
- To simulate user flows without full visual design (Correct answer)
- To generate production-ready code
- To document accessibility compliance
Correct answer: To simulate user flows without full visual design
Clickable wireframes allow stakeholders and users to navigate simulated flows, testing task completion before committing to full visual design.
Question 4: Which interaction design principle states that systems should always keep users informed about what is happening?
- Aesthetic and minimalist design
- Match between system and real world
- Visibility of system status (Correct answer)
- User control and freedom
Correct answer: Visibility of system status
Nielsen's heuristic 'Visibility of system status' states that systems must provide timely, appropriate feedback so users always know the current state.
Question 5: In Fitt's Law, which factor most directly affects the time needed to acquire a target?
- The color contrast of the target
- The distance to and size of the target (Correct answer)
- The number of items on screen
- The user's cognitive load
Correct answer: The distance to and size of the target
Fitt's Law states that movement time is a function of both the distance to the target and the size of the target — farther and smaller targets take longer to acquire.
Question 6: What distinguishes a high-fidelity prototype from a low-fidelity prototype?
- High-fidelity prototypes are always built in code
- High-fidelity prototypes closely resemble the final product in visual design and interaction (Correct answer)
- Low-fidelity prototypes require more time to build
- High-fidelity prototypes are only used for developer handoff
Correct answer: High-fidelity prototypes closely resemble the final product in visual design and interaction
High-fidelity prototypes closely replicate the final product's visual appearance and behavior, making them suitable for later-stage usability testing.
Question 7: Which principle of interaction design emphasizes reducing the number of actions required to complete a task?
- Progressive disclosure
- Efficiency of use (Correct answer)
- Error prevention
- Recognition over recall
Correct answer: Efficiency of use
Efficiency of use focuses on minimizing the steps and effort required, allowing both novice and expert users to accomplish tasks with minimal friction.
