scope:

This International Standard gives minimum specifications for the image quality and legibility of displays containing dynamic (changeable) visual information presented to the driver of a road vehicle by on-board transport information and control systems (TICS) used while the vehicle is in motion. These specifications are intended to be independent of display technologies, while test methods and measurements for assessing compliance with them have been included where necessary. It is applicable to mainly perceptual, and some basic cognitive, components of the visual information: these include character legibility and colour recognition. The standard will improve the ease with which the driver can recognize the in-vehicle texts and symbols while the car is in motion, thus decreasing their mental workload and visual distraction. For example: red characters on blue backgrounds should be avoided since the eyes will have trouble focusing on these colour combinations. Deep eds can also be confusing for people who are colour blind.
