Lesson 4 Flashcards
is the practice of designing
interactive digital products and
environments.
Interaction design (IxD)
provides users with information about what action they have taken and the system’s response to it.
Feedback
example of feedback
Visual, Audio, Tactile
Button changes color after a click
Visual
Notification sounds after sending a message
Audio
Vibration when a key is pressed on a smartphone
Tactile
Reduces uncertainty, guides the user, and improves interaction flow by confirming successful actions
Feedback
ensures that similar actions and elements
behave in the same way across the system.
Consistency
Types of Consistency
Internal Consistency
External Consistency
Consistency within a product’s interface (e.g., button styles across
different screens).
Internal Consistency
Consistency with conventions users already know from other products (e.g., common placement of the navigation bar).
External Consistency
Consistent design reduces the learning curve and
increases predictability, making the product easier to use.
consistency
refers to the perceived or actual properties of an object that indicate how it should be used.
Affordances
Helps users understand how to interact with an element
at first glance without needing instructions.
Affordances
refers to making important information and interactive elements clear and easy to find.
Visibility
Good visibility minimizes cognitive load, allowing users
to quickly locate what they need to complete tasks (T or F)
T
is the relationship between controls and their
effects in the real world.
Mapping
Natural mapping reduces errors and makes interactions
more intuitive. (t or F)
T
allows designers to test
ideas, gather feedback, and iterate
designs before finalizing them
Prototyping
Types of Prototypes
Low-Fidelity Prototypes
High-Fidelity Prototypes
- 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.
Low-Fidelity Prototypes
Advantage of Low-Fidelity Prototypes
- Quick to create and modify.
- Cost-effective, encouraging exploration of multiple ideas.
- Ideal for early-stage design feedback on structure and functionality.
Limitations of Low-Fidelity Prototypes
- Doesn’t accurately represent user interactions or final aesthetics.
Advantage of High-Fidelity Prototypes
- Allows for more realistic testing of interactions.
- Useful for presenting to stakeholders.
- Helps developers understand detailed design specifications.
