Intuitive User Interface
Adapted from
UX Design Edge
.
Affordance
- does the UI allow user to predict future state.
Expectation
- are triggers labelled and/or adopt universal symbols (i.e. the right facing triangle for 'play')
Efficiency
- the number of triggers needed to reach a desired state is the absolute minimum
Responsiveness
- the UI provides instantaneous feedback on whether a trigger is being processed and/or a state has been changed.
Forgiveness
- a user-induced error can be caught and corrected and/or undoned.
Explorability
- (
IMO
not relevant to physical UI) users can navigate throughout the UI without unintended consequences, or of getting lost.
