Q

What are Jakob’s Ten Usability Heuristics?

VMUCERFARH

A
  • Visibility of System Status
  • Match between the System and Real World
  • User Control and Freedom
  • Consistency and Standards
  • Error Prevention
  • Recognition rather than Recall
  • Flexibility and Efficiency of Use
  • Aesthetic and Minimalist Design
  • Recognize, Diagnose, and Recover from Errors
  • Help and Documentation
17
Q

Designs should keep users informed
about what is going on, through
appropriate, timely feedback.

A
  • Visibility of System Status
18
Q

The design should speak the users’
language. Use words, phrases, and
concepts familiar to the user, rather than
internal jargon

A
  • Match between the System and Real World
19
Q

Users often perform actions by mistake.
They need a clearly marked “emergency
exit” to leave the unwanted action

A
  • User Control and Freedom
20
Q

Users should not have to wonder whether
different words, situations, or actions
mean the same thing. Follow platform
conventions.

A
  • Consistency and Standards
21
Q

Minimize the user’s memory load by
making elements, actions, and options
visible. Avoid making users remember
information

A
  • Recognition rather than Recall
21
Q

Good error messages are important, but
the best designs carefully prevent
problems from occurring in the first place.

A
  • Error Prevention
22
Q

Shortcuts — hidden from novice users —
may speed up the interaction for the
expert user.

A
  • Flexibility and Efficiency of Use
23
Q

Interfaces should not contain information
which is irrelevant. Every extra unit of
information in an interface competes with
the relevant units of information.

A
  • Aesthetic and Minimalist Design
24
Q

Error messages should be expressed in
plain language (no error codes), precisely
indicate the problem, and constructively
suggest a solution.

A
  • Recognize, Diagnose, and Recover from Errors
25
Q

It’s best if the design doesn’t need any
additional explanation. However, it may be
necessary to provide documentation to
help users complete their tasks

A
  • Help and Documentation
