Use visual feedback and visual means for attracting attention when:
· The information is long and complex
· The information will be referred to later
· For alerts and warnings which do not need the user’s immediate attention
· The user’s aural system is already overburdened
· The user is not moving about
· A verbal respone is not needed
· Illumination is good
Auditory channel – hearing – ear/telinga

sound is a good way of attracting attention since people
respond more quickly to auditory signals than to visual signals
