Road vehicles — Ergonomic aspects of transport information and control systems — Specifications and test procedures for in-vehicle visual presentation
ISO 15008:2017 specifies minimum requirements for the image quality and legibility of displays containing dynamic (changeable) visual information presented to the driver of a passenger car by on-board transport information and control systems (TICS) used while the vehicle is in motion. Heavy vehicles are excluded for the requirements of contrast and font size since these chapters reference ISO 4513 which is only applicable for passenger vehicles. These requirements are intended to be independent of display technologies. Reference to test methods and measurements for assessing compliance with them have been included where necessary. ISO 15008:2017 is applicable mainly to perceptual, and some basic cognitive, components of the visual information, including character legibility and colour recognition. It is not applicable to other factors affecting performance and comfort, such as coding, format and dialogue characteristics, or to displays using: - characters presented as a part of a symbol or pictorial information (e.g.CD symbol); - superimposed information on the external field (e.g. head-up displays); - pictorial images (e.g. rear view camera); - maps and topographic representations (e.g. those for setting navigation systems); or - quasi-static information (e.g. AM/PM, km/miles, kPa/PSI, On/Off information).

L'ISO 15008 :2017 spécifie les exigences minimales de qualité d'image et de lisibilité d'image des afficheurs qui fournissent au conducteur d'une voiture particulière des informations visuelles dynamiques (changeantes) issues des systèmes de commande et d'information des transports (TICS) embarqués utilisables pendant que le véhicule est en mouvement. Les véhicules lourds sont exclus pour les exigences de contraste et de taille de police de caractères, car ces paragraphes font référence à la norme ISO 4513 qui ne s'applique qu'aux voitures particulières. Ces exigences sont indépendantes des technologies d'affichage utilisées, alors que les méthodes d'essai et les mesures qui permettent d'évaluer la conformité aux spécifications sont indiquées si nécessaire. L'ISO 15008 :2017 est applicable principalement aux composantes perceptives et à certaines composantes cognitives fondamentales de l'information visuelle, y compris la lisibilité des caractères et la reconnaissance des couleurs. Elle n'est pas applicable à d'autres facteurs affectant les performances et le confort, tels que le codage, le format et les caractéristiques du dialogue, ni aux afficheurs utilisant: - des caractères présentés comme une partie d'un symbole ou d'information graphique (par exemple symbole CD), - des informations superposées à la scène extérieure au véhicule (par exemple affichages tête haute), - des images graphiques (par exemple d'une caméra de vue arrière), - des cartes et des représentations topographiques (par exemple celles pour régler les systèmes de navigation), ou - des informations quasi statiques (par exemple a.m./p.m., km/miles, kPa/psi, information On/Off).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Introduction
Driving is a complex task requiring continuous allocation of attentional resources to both driving
and non-driving tasks. Because of this, driving is an interactive balance between cognitive, physical,
somatosensory, visual and psychomotor skills.
Driver and vehicle form an integrated system that includes the environment, vehicle controls, and
displays collectively defined as the transport information and control systems (TICS). Since driving
is an interactive systems activity, vehicle characteristics in combination with human capabilities
constitute important factors in the performance of this TIC system.
In order to achieve optimal driver performance, the purpose of TICS is to support drivers in their
primary task such that performance, comfort and safety are increased and overall driver workload is
not negatively influenced by the use of TICS. One set of factors influencing this process involves the
characteristics of visual displays. Specifically, those aspects of displays designed to accommodate
human capabilities, the range of illumination conditions and location of the display with respect
to the driver. This is especially important since visual specifications must include a wide range of
environmental conditions and constitute only one necessary condition for adequate performance,
comfort and workload. The purpose of this document is to standardize visual presentation.
INTERNATIONAL STANDARD ISO 15008:2017(E)
Road vehicles — Ergonomic aspects of transport
information and control systems — Specifications and test
procedures for in-vehicle visual presentation
1 Scope
This document specifies minimum requirements for the image quality and legibility of displays
containing dynamic (changeable) visual information presented to the driver of a passenger car by on-
board transport information and control systems (TICS) used while the vehicle is in motion. Heavy
vehicles are excluded for the requirements of contrast and font size since these chapters reference
ISO 4513 which is only applicable for passenger vehicles. These requirements are intended to be
independent of display technologies. Reference to test methods and measurements for assessing
compliance with them have been included where necessary.
This document is applicable mainly to perceptual, and some basic cognitive, components of the
visual information, including character legibility and colour recognition. It is not applicable to other
factors affecting performance and comfort, such as coding, format and dialogue characteristics, or to
displays using:
— characters presented as a part of a symbol or pictorial information (e.g.CD symbol);
— superimposed information on the external field (e.g. head-up displays);
— pictorial images (e.g. rear view camera);
— maps and topographic representations (e.g. those for setting navigation systems); or
— quasi-static information (e.g. AM/PM, km/miles, kPa/PSI, On/Off information).
