Document Summary
The display of visual, auditory and tactile information. Human factors is primarily concerned with indirect information (i. e information that is represented by displays) Qualitative (approximation of a changeable variable) higher, lower, heavier, lighter. Warning (emergency or unsafe conditions: usually are strong alerting function b/c typically require immediate action not always. Representational (graphic representation: trying to get around literacy problem - used in airports where there are cultural differences and language differences. Identification (of a particular condition, i. e. , road lanes) Must be prominent, novel, and relevant: visibility. Must be visible under all expected viewing conditions (e. g. A lot of times people forget their display is needed in sub- reflectorized road signs) optimal viewing conditions: legibility making sure 2 components of static display stand out. Consideration of contrast ration (black on white is best) Size and simplicity of lettering simplicity is important esp. during hypervigilance (incr stress causes system to be less efficient at dealing w/complexities: intelligibility.
