LESSON 5 Flashcards
focuses on
assessing how easy and
effective it is for users to
interact with a product or
interface.
Usability evaluation
Effective usability evaluation
methods ensure that designs
are ___ and meet user __
user-friendly, needs
This method involves
usability experts reviewing
an interface against a
predefined set of usability
principles
Heuristic Evaluation
communicate clearly to users what the system’s state is - no action with consequences to users should be taken without informing them
- Visibility of system status
Nielsen’s 10 Heuristics are
Visibility of system status
Match between system and the real world
User control and freedom
Consistency and standards
Error prevention
Recognition rather than recall
Flexibility and efficiency of use
Aesthetic and minimalist design
Help users recognize, diagnose,
and recover from errors
Help and documentation
Ensure that users can understand meaning without having to go look up a word’s definitions
- Match between system and the real world
show a clear way to exit the current interaction, like a cancel button
- User control and freedom
improve learnability by maintaining both types of consistency
- Consistency and standards
avoid slips by providing helpful constraints and good defaults
- Error prevention
Let people recognize information in the interface, rather than forcing them to remember (“recall”) it
- Recognition rather than recall
provide accelerators like keyboard shortcuts and touch gestures
- Flexibility and efficiency of use
keep the content and visual design of UI focused on the essentials
- Aesthetic and minimalist design
Use traditional error-message visuals, like bold, red text
- Help users recognize, diagnose,
and recover from errors
Ensure that the help documentation is easy to search
- Help and documentation
This method involves observing real users as they complete tasks on the system. It allows designers to identify where users struggle and what works well.
