Road vehicles - Ergonomic aspects of transport information and control systems - Specifications and test procedures for in-vehicle visual presentation (ISO 15008:2017)
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).

Dieses Dokument legt Mindestanforderungen an die Bildqualität und Lesbarkeit von Displays für die Darstellung von dynamischen (sich ändernden) visuellen Informationen fest, die dem Fahrer eines Personenkraftfahrzeuges von einem internen Fahrerinformations- und Assistenzsystem (en: Transport Information and Control System, TICS) während der Fahrt bereitgestellt werden. Schwerlastfahrzeuge sind von den Anforderungen an Kontraste und Schriftgrößen ausgenommen, da in diesen Abschnitten auf ISO 4513 Bezug genommen wird, die nur für Personenkraftfahrzeuge anwendbar ist. Es ist vorgesehen, dass diese Anforderungen unabhängig von speziellen Displaytechnologien sind. Verweisungen auf Test- und Messmethoden sind dort eingefügt worden, wo sie zur Überprüfung und Einhaltung der Anforderungen notwendig sind.
Dieses Dokument gilt hauptsächlich für Aspekte der Wahrnehmung und einige grundlegende kognitive Komponenten der visuellen Information; diese schließen Lesbarkeit von Zeichen und Farberkennung ein. Sie gilt nicht für andere Faktoren, welche die Leistung und den Komfort beeinflussen, wie z. B. Kodierung, Format und Dialog-Formen, oder für Displays, die
- Zeichen verwenden, die Teil eines Symbols oder einer bildhaften Information sind (z. B. CD-Symbol);
- dem äußeren Sichtfeld überlagerte Informationen enthalten (z. B. Head-up-Displays);
- bildhafte Informationen darstellen (z. B. Rückfahrkamera);
- Karten und topographische Darstellungen anzeigen (z. B. für Einstellmöglichkeiten von Navigationssystemen); oder
quasi-statische Informationen anzeigen (z. B. Angaben zu AM/PM, km/Meilen, kPa/PSI, An/Aus).

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).

Ta dokument določa minimalne zahteve za kakovost slike in berljivost zaslonov, ki vsebujejo dinamične (spremenljive) vizualne informacije, ki jih vozniku potniškega vozila prikazujejo
transportne informacije in kontrolni sistemi v vozilu (TICS), ki se uporabljajo, ko se vozilo premika. Zahteve glede kontrasta in velikosti pisave ne veljajo za težka vozila, ker se ta poglavja sklicujejo na standard ISO 4513, ki se uporablja le za potniška vozila. Te zahteve niso odvisne od tehnologij za prikaz. Po potrebi so bili vključeni sklici na preskusne metode in meritve za ocenjevanje skladnosti z njimi.
Ta dokument se uporablja predvsem za zaznavne in nekatere osnovne kognitivne komponente vizualnih informacij, vključno z berljivostjo znakov in prepoznavanjem barv. Ne uporablja se za druge dejavnike, ki vplivajo na zmogljivost in udobje, kot so kodiranje, oblika in značilnosti zapisa, ali za zaslone, ki uporabljajo:
– znake, ki so predstavljeni kot del simbola ali slikovne informacije (npr. simbol za CD);
– informacije, prikazane na zunanjem polju (npr. zasloni v višini oči);
– slike (npr. kamera za vzvratno vožnjo);
– zemljevidi in topografske predstavitve (npr. za nastavitev navigacijskih sistemov); ali
- navidezno statične informacije (npr. AM/PM, km/milje, kPa/PSI, informacije o vklopu/izklopu).

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).

4.2 Design viewing position and illumination range
4.2.1 Design viewing position
The requirements in this subclause are applicable to displays in their installed vehicle locations, as seen
from any point in the driver eyellipses according to ISO 4513 (for passenger vehicles only).
If the display is fixed to the vehicle, the relevant requirements shall be complied with from the
rearmost point of the cyclopean eyellipse. If the orientation of the display is adjustable, the display may
be adjusted so that a position can be found in which all the relevant requirements are complied with
simultaneously. For direct sunlight conditions, the requirements of contrast (see 4.3.2) shall only be
fulfilled in the direction of the critical specular line (CSL) (see Figure 1).
Standard default values for angles (45°/20°) as an alternative for direct sunlight measurements are
acceptable (see SAE J1757/1).

The EN ISO 15008:2017 standard focuses on ensuring ergonomic aspects of transport information and control systems (TICS) in road vehicles, particularly in passenger cars. Its primary scope is to establish minimum requirements regarding the image quality and legibility of displays that provide dynamic visual information to drivers while operating vehicles. This specificity underscores its relevance in enhancing driver safety and optimizing user experience, as it addresses critical elements of visibility essential for the effective use of in-vehicle information systems. One of the strengths of ISO 15008:2017 lies in its comprehensive approach to the perceptual components of visual information, including character legibility and color recognition. By prioritizing these aspects, the standard promotes the development of displays that are not only functional but also intuitive, reducing cognitive load on drivers. Moreover, the inclusion of references to test methods and measurements supports objectivity and consistency in evaluating compliance, ensuring that manufacturers can reliably assess their displays against established benchmarks. While the standard articulates clear requirements, it wisely excludes heavy vehicles from specific criteria related to contrast and font size, recognizing the different demands of various vehicle types. By linking to ISO 4513 for relevant specifications related to passenger vehicles, ISO 15008:2017 provides a structured framework for developers that is both flexible and targeted. Additionally, the standard's emphasis on dynamic visual information makes it particularly relevant in today’s rapidly evolving automotive landscape, where in-vehicle displays are becoming increasingly complex. However, it strategically delineates the boundaries of its applicability by specifying that it does not cover various display types, such as pictorial representations or quasi-static information. This focus enables the standard to maintain clarity and coherence, ensuring that stakeholders understand its intended application and limitations. Thus, EN ISO 15008:2017 stands as a pivotal standard in the automotive industry, driving forward the development of safer and more ergonomic driver interfaces. Its detailed specifications and testing procedures are vital for ensuring that visual information presented to drivers is both effective and user-friendly, ultimately contributing to improved road safety and driver comfort.
