How does visual hierarchy help users in UI design?
Choices:
- It guides users’ attention to important elements

- It makes the interface more complicated
- It reduces usability
It guides users’ attention to important elements
Hick’s Law states that the more choices a user has, the longer it will take them to make a decision.

True
In the early days of computing, how did users interact with computers?
Choices:

- Using graphical user interfaces (GUIs)
- Through command-line interfaces (CLIs)
- By touching the screen
Through command-line interfaces (CLIs)
How does feedback help learning in interfaces?
Choices:
- It discourages users from using the system
- It reinforces correct actions and helps users learn faster
- It prevents users from interacting with the system
- It has no impact on usability
It reinforces correct actions and helps users learn faster
Which Gestalt principle helps users understand grouping in interfaces?
Choices:
- Proximity
- Closure
- Continuity
- Simplicity
Proximity
Which memory type briefly holds sensory input before processing?
Choices:
- Sensory memory
- Short-term memory
- Working memory
- Long-term memory
Sensory memory
What is one main advantage of a GUI over a CLI?
Choices:
- It requires users to memorize commands
- It is more difficult to use
- It provides a more intuitive and visual interaction
- It is slower and less efficient
It provides a more intuitive and visual interaction
What is the difference between sensation and perception?
Choices:
- Sensation is how we interpret stimuli, while perception is receiving them
- Sensation is about receiving stimuli, while perception is about interpreting them
- Sensation happens in computers, while perception happens in humans
- Sensation requires active attention, while perception is automatic
Sensation is about receiving stimuli, while perception is about interpreting them
What is one major challenge in designing Human-Computer Interfaces?
Choices:
- Making computers slower
- Ensuring the interface is user-friendly for different types of users
- Removing all visual elements from interfaces
- Preventing users from interacting with technology
Ensuring the interface is user-friendly for different types of users
Which of the following is an example of a Graphical User Interface (GUI)?
Choices:
- MS-DOS
- Windows operating system
- Command Prompt
- Linux Terminal
Windows operating system
Why is consistency important in UI design?
Choices:
- It helps users build accurate mental models
- It confuses users
- It makes learning harder
- It reduces usability
It helps users build accurate mental models
What is a mental model?
Choices:
- A visual design of an interface
- A user’s internal understanding of how a system works
- A programming method
- A machine learning algorithm
A user’s internal understanding of how a system works
How do voice and natural language interfaces improve user experience?
Choices:
- By requiring complex programming knowledge
- By allowing users to interact with devices using spoken commands
- By making devices more difficult to use
- By replacing all other forms of interaction
By allowing users to interact with devices using spoken commands
According to Fitts’s Law, smaller buttons placed far apart are easier for users to click.
Choices:
- True
- False
False
What is the main challenge of divided attention in HCI?
Choices:
- Users can only focus on one thing at a time
- Multitasking can lead to errors and reduced efficiency
- Users cannot complete any task
- It improves memory recall
Multitasking can lead to errors and reduced efficiency
Why are mental models important in UI design?
Choices:
- They make systems harder to use
- They help designers align interfaces with users’ expectations
- They focus only on visuals, not functionality
- They are not relevant in HCI
They help designers align interfaces with users’ expectations
Providing feedback enhances learning and usability.
Choices:
- True
- False
True
Affordances in interface design refer to the perceived functionality of an object, such as a button that looks clickable.
Choices:
- True
- False
True
What is an affordance in HCI?
Choices:
- A property of an object that suggests how it can be used
- A decorative UI element
- A programming technique
- A psychological theory
A property of an object that suggests how it can be used
