Question 8

ensures that similar actions and elements
behave in the same way across the system.

Answer 8

Consistency

Question 9

Types of Consistency

Answer 9

Internal Consistency
External Consistency

Question 10

Consistency within a product’s interface (e.g., button styles across
different screens).

Answer 10

Internal Consistency

Question 11

Consistency with conventions users already know from other products (e.g., common placement of the navigation bar).

Answer 11

External Consistency

Question 12

increases predictability, making the product easier to use.

Answer 12

consistency

Question 13

refers to the perceived or actual properties of an object that indicate how it should be used.

Answer 13

Affordances

Question 14

Helps users understand how to interact with an element
at first glance without needing instructions.

Answer 14

Affordances

Question 15

refers to making important information and interactive elements clear and easy to find.

Answer 15

Visibility

Question 16

Good visibility minimizes cognitive load, allowing users
to quickly locate what they need to complete tasks (T or F)

Answer 16

T

Question 17

is the relationship between controls and their
effects in the real world.

Answer 17

Mapping

Question 18

Natural mapping reduces errors and makes interactions
more intuitive. (t or F)

Answer 18

T

Question 19

allows designers to test
ideas, gather feedback, and iterate
designs before finalizing them

Answer 19

Prototyping

Question 20

Types of Prototypes

Answer 20

Low-Fidelity Prototypes
High-Fidelity Prototypes

Question 21

• Basic, rough representations of ideas, often created with paper or simple
  digital tools.
• Focuses on the structure and flow rather than aesthetics or detailed
  interactions.

Answer 21

Low-Fidelity Prototypes

Question 22

Advantage of Low-Fidelity Prototypes

Answer 22

• Quick to create and modify.
• Cost-effective, encouraging exploration of multiple ideas.
• Ideal for early-stage design feedback on structure and functionality.

Question 23

Limitations of Low-Fidelity Prototypes

Answer 23

• Doesn’t accurately represent user interactions or final aesthetics.

Question 24

Advantage of High-Fidelity Prototypes

Answer 24

• Allows for more realistic testing of interactions.
• Useful for presenting to stakeholders.
• Helps developers understand detailed design specifications.

Question 24

• Detailed and interactive prototypes that closely resemble the final
  product in terms of functionality and appearance
• Simulates most of the user interactions and design elements.

Answer 24

High-Fidelity Prototypes

Question 25

Limitation of High-Fidelity Prototypes

Answer 25

• Time-consuming and resource-intensive.
• Higher costs associated with creating detailed designs.

Question 26

_____ are ideal for the
initial conceptual phase, while ____ are better suited for later stages when the design is nearly finalized.

Answer 26

Low-fidelity prototypes, high-fidelity prototypes

Question 27

If the goal is to test basic ideas and flow, low fidelity prototypes are _____. For testing user interactions and UI
aesthetics, high-fidelity prototypes are more ___

Answer 27

sufficient, appropriate
