Object display
When operator need to integrate information form
several variables to understand the state of a system or
process.
Emergent feature: Combining dimensions into a
perceptual object.
Separate display must also be provided.

Qualitative visual display
Quantitative data may be used as the basis for
qualitative reading. However, best for quantitative
reading may not necessarily best for qualitative
reading.
Use of color code
Use of shape
Check reading: Use of an instrument to ascertain
whether the reading is normal.
Arrangement of the displays

Signal and warning light
Detectability of signal and warning lights
Size, luminance, and exposure time
Color of lights
Low signal-to-background brightness contrast, use red .
When high brightness contrast, color is not important.
Flash rate of lights: 3 to 10 per second
