3.1 adaptation

Adjust the sensitivity of the eye to the brightness of the observation field
The occurrence rate of dark adaptation was lower than that of light adaptation.
3.2 blinking
A periodic change in the brightness of an expected light or visual message, usually from "off" to a given value, usually used to attract attention
Note: terms and definitions related to photometric quantities (e.g., illuminance, brightness, contrast and saturation) are given in CIE 17.4:1987.
3.3 brightness
The subjective attribute of light perception, in which the stimulus seems to be more or less intense or emit more or less light
3.4 critical mirror reflection CSL
A line from the center of the monitor to the center of the eye ellipse
3.5 color
Having a hue or coloring that looks different from neutral gray with the same brightness
Note that it is related to the color properties of visual stimuli.
3.6 comparison C
The luminance difference Lhigh of an area in the "on" state (for example, a stroke of a character in the negative case) subtracts the ratio between the luminance llow and the luminance llow of the same region in its "dark" state
Note 1: C = Lhigh low / llow
Note 2: terms and definitions related to photometric quantities (e.g. illuminance, brightness, brightness contrast and saturation) are given in CIE 17.4:1987.
3.7 contrast RC
The ratio between brightness Lhigh and luminance llow
Note 1: RC = Lhigh / low
Note 2: terms and definitions related to photometric quantities (e.g. illuminance, brightness, brightness contrast and saturation) are given in CIE 17.4:1987.
3.8 torus ellipse
Elliptical volume combines the left and right eye ellipses of the driver into a single volume at the center between them
3.9 daytime conditions
Conditions of diffuse ambient light
3.10 direct sunlight conditions
Observation conditions are mainly affected by direct sunlight from the sun on the display surface
3.11 dynamic information
Information with more than two stages of change
3.12 eye range of motion
The elliptical shape of the driver's eye area, as defined in ISO 4513
Note 1 see definition of 95th percentile eye ellipse in ISO 4513. Note 2: it is an abbreviation of the words "eye" and "ellipse".
3.13 flicker
Unconscious perceptual temporal changes in the brightness of visual stimuli, usually caused by a refresh process of the display content or by a change in the brightness of the backlight
Note: terms and definitions related to photometric quantities (e.g., illuminance, brightness, contrast and saturation) are given in CIE 17.4:1987.
3.14 disability glare
Dazzle or disable effects caused by bright light
Note that this is a retinal effect, mainly caused by light scattering in the eye, producing a luminous veil on the retinal image, which reduces contrast.
3.15 uncomfortable glare
Disperse or destroy the influence of bright spot source in the field of vision
Note that this is a perceptual effect that interferes with visual attention and selection.
