Primary cues (location, size and shape of visual objects) enable fast recognition; therefore, these should be used in routine and recovery interaction in order to facilitate recognition of the interaction
mode. Primary cues (location, size and shape of visual objects) enable fast recognition; therefore, these should be used in routine and recovery interaction in order to facilitate recognition of the interaction
mode.
In routine interaction,
secondary cues (images, colors and texture) may be used to distinguish among the screens. In recovery interaction, this is not required because users do not have many chances to gain
perception skills with these screens.
For
alerting, we should use primary cues to enable fast and reliable recognition of critical
risks.
