What is the primary focus of User-Centered Design (UCD)?
System functionality
User needs and capabilities
Cost reduction
Programming efficiency
Which of the following is NOT a principle of Nielsen’s heuristics?
Error prevention
Aesthetic and minimalist design
Learnability
User control and freedom
In the Waterfall model, which phase comes immediately after Architectural Design?
Requirements Specification
Coding
Maintenance
Detailed Design
What distinguishes a principle from a design rule?
Principles are theoretical, while design rules are practical.
Design rules apply only to hardware, not software.
Principles are specific to programming languages.
Design rules can only be interpreted in one way.
According to Dix’s principles, which one relates to reducing cognitive load?
Recoverability
Predictability
Learnability
Flexibility
What is the purpose of a hierarchical task analysis (HTA) in task analysis?
To create a programming structure.
To define the UI components.
To enforce industry standards.
To break down tasks into subtasks for better understanding.
What is a major reason for evaluating design options with the Simplex One model?
To ensure that system performance is maximized.
To improve long-term memory retention.
To analyze how different cognitive zones interact with the system.
To create standardized interfaces.
In UCD, what is the main purpose of the prototype implementation phase?
To finalize the software.
To provide a testable model for user evaluation.
To gather project funding.
To complete coding.
What is a key limitation of the Waterfall model in interactive system design?
It allows too much user feedback.
It is too iterative.
It does not accommodate iterative design well.
t requires continuous evaluation.
Which of the following is a major challenge in requirements gathering?
Users do not care about usability.
Prototyping is too expensive.
It is difficult to explicitly describe what is needed.
Hierarchical task analysis is unnecessary.
What is a key characteristic of standards in HCI?
They are loosely interpreted guidelines.
They are optional for system designers
They are only used in mobile app development.
They are guidelines with high authority and must be applied.
Which design principle ensures that users do not have to remember too much information?
Recognition rather than recall
Aesthetic and minimalist design
Help and documentation
Error prevention
In the Simplex One model, which zone ensures that users can track their progress effectively?
Sensory and Perceptual Zone
Abstract Working Zone
Executive Functions Zone
Output Zone
Why is iteration important in UCD?
It increases system complexity.
It improves usability by refining designs based on user feedback.
It ensures minimal user input.
It allows for faster programming.
What is an example of a design rule in HCI?
Always position the waste bin in the bottom right-hand corner.
Reduce cognitive load.
Be consistent.
Know the user population.
What is the main goal of usability heuristics?
To replace user testing.
To create complex software architectures.
To enforce strict legal standards.
To guide the design of user-friendly interfaces.
Which of the following best describes task analysis in HCI?
Understanding how users interact with a system to improve design.
educing system costs through automation.
The process of programming user interfaces.
Writing system documentation for user training.
In UCD, what is an advantage of storyboarding?
It requires advanced programming knowledge.
It focuses on the technical implementation.
It replaces prototype testing.
It provides a low-cost way to visualize system interactions.
According to Nielsen’s heuristics, why is "help and documentation" important?
It ensures users never make mistakes.
It helps users resolve issues when they arise.
It replaces the need for an intuitive interface.
It increases system security.
What is the primary reason for conducting evaluations in UCD?
To finalize the design.
To meet legal requirements.
To verify if the system meets user needs and expectations.
To speed up the development process.
