Jakob Nielsen’s Ten Usability Heuristics2


Слайд 5
Design should follow the guidelines and conventions of similar systems, applications,

or websites
Users should be able to make inferences about labels and terms by drawing from their experiences with similar interfaces and systems

Consistency and Standards


Слайд 6
Design to prevent errors


Error Prevention


Слайд 7
Keep the amount users have to remember to a minimum
Don’t expect

users to remember specific, detailed information about system
Interface should be designed to allow users to easily recognize or intuit functionality

Recognition Rather than Recall


Слайд 8
Design should accommodate both experienced and inexperienced users
Flexibility and Efficiency of

Use

Слайд 9
Design should include only relevant, minimally needed information
Unnecessary information:
Makes it harder

to see important information
Decreases design’s overall usability

Aesthetic and Minimalist Design


Слайд 10
Use plain language to indicate problem and suggest solution
Error messages should:
Be

clear, specific, easy to understand
Be meaningful to the user
Provide immediate feedback and specific guidance on how to recover from the error

Help Users Recognize, Diagnose, and Recover from Errors


Слайд 11
Documentation should be:
Helpful and relevant in the user’s context
Focused on the

user’s task
Easily searchable and accessible

Help and Documentation


Слайд 12
What have you learned from checking your design against all ten

principles combined and how will you improve your design as a result?
