ISO 15008:2003 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 an on-board transport information and control system (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.
ISO 15008:2003 is applicable to mainly perceptual, and some basic cognitive, components of the visual information: these include character legibility and colour recognition. It is not applicable to other factors affecting performance and comfort such as coding, format and dialogue characteristics, nor to displays using the following: superimposed information on the external field (e.g. head-up displays), pictorial images (e.g. closed-circuit TV for reversing), maps and topographic representations (e.g. those for setting navigation systems), static information (e.g. control labels, telltales).
