Road vehicles - Measurement of driver visual behaviour with respect to transport information and control systems - Part 1: Definitions and parameters (ISO 15007-1:2014)

This part of ISO 15007 defines key terms and parameters applied in the analysis of driver visual
behaviour focused on glance and glance-related measures. These terms and parameters can be applied
in environments from real-world driving experiments to laboratory-based driving simulator studies.
The procedures described in this part of ISO 15007 could also apply to more general assessments
of driver visual behaviour without the introduction of TICS-specific systems. The parameters and
definitions described below are intended to assist development of a common source of reference for
driver visual behaviour data.
Minimum requirements for reporting the results of Transport Information and Control Systems (TICS)
evaluations are provided.
Further guidance including the specification of how to analyse and present the results of studies of visual
behaviour is available in other ISO publications (see, for example, ISO 2854 and ISO/TR 13425:2006).
However, data collected and analysed according to this standard will allow comparisons to be performed
across different TICS applications and experimental scenarios.

Véhicules routiers - Mesurage du comportement visuel du conducteur en relation avec les systèmes de commande et d'information du transport - Partie 1: Définitions et paramètres (ISO 15007-1:2014)

ISO 15007-1:2014 définit les termes et les paramètres essentiels utilisés dans l'analyse du comportement visuel des conducteurs axée sur des mesures des coups d'?il et associées aux coups d'?il. Ces termes et paramètres sont applicables dans des environnements allant des expériences de conduite en situation réelle aux études sur simulateur de conduite en laboratoire.
Les modes opératoires décrits dans la présente partie de la norme ISO 15007 pourraient également s'appliquer à des évaluations plus générales du comportement visuel des conducteurs sans l'introduction de systèmes TICS spécifiques. Les paramètres et définitions décrits ci-dessous visent à faciliter l'élaboration d'une source commune de référence en matière de données de comportement visuel des conducteurs.
Elle fournit les exigences minimales relatives aux comptes-rendus de résultats d'évaluation de TICS (systèmes de commande et d'information du transport).
D'autres recommandations, y compris la spécification du mode d'analyse et de présentation des résultats d'études du comportement visuel obtenus sont disponibles dans d'autres publications de l'ISO (voir, par exemple, la norme ISO 2854 et le rapport technique ISO/TR 13425:2006). Les données recueillies et analysées conformément à la présentent norme permettront toutefois d'effectuer des comparaisons sur différentes applications des TICS et différents scénarios expérimentaux.

Cestna vozila - Merjenje voznikovega vizualnega obnašanja glede na prometne informacije in nadzorne sisteme - 1. del: Definicije in parametri (ISO 15007-1:2014)

Ta del standarda ISO 15007 določa glavne izraze in parametre, uporabljene pri analizi voznikovega vizualnega obnašanja s poudarkom na pogledu in s pogledom povezanih meritvah. Te izraze in parametre je mogoče uporabiti v okoljih z realnimi preskusi vožnje in študijami s simulatorjem vožnje v laboratoriju. Postopki, opisani v tem delu standarda ISO 15007, se lahko uporabljajo tudi za bolj splošne ocene voznikovega vizualnega obnašanja brez uvedbe sistemov, značilnih za TICS. Parametri in definicije, opisani spodaj, so namenjeni za pomoč pri razvoju skupnega vira referenc za podatke o voznikovem vizualnem obnašanju.
Navedene so minimalne zahteve za poročanje rezultatov ocenjevanj
glede na prometne informacije in nadzorne sisteme (TICS).
Dodatna navodila, vključno s specifikacijo načina analize in predstavitve rezultatov študij vizualnega obnašanja, so na voljo v drugih publikacijah ISO (glejte na primer ISO 2854 in ISO/TR 13425:2006). Podatki, zbrani in analizirani v skladu s tem standardom, omogočajo primerjave glede na različne uporabe prometnih informacij in nadzornih sistemov ter preskusne scenarije.

Introduction

Vision provides the primary source of information available to a driver. Information is gathered by

looking at objects and events and this in turn affords control and navigation of the vehicle in the road

traffic environment. Assessment of a driver’s visual behaviour provides a method of quantifying the

[1]

driver’s visual allocation to the roadway or in-vehicle information sources (see Reference ).

Transport Information and Control Systems (TICS) applications for vehicles may have visual displays

that can present a range of driver-selected information. If these visual displays have associated controls

(e.g. to select a zoom level or menu option) then these associated hand-control activities may also be

visually guided and become part of the visual behaviour associated with a display/TICS application.

For this reason it may be important to consider not only the visual behaviour in relation to information

display, but also the duration and frequency of glances following driver controlled actions.

Comparisons between specific vehicle systems have been made more difficult because the studies were

conducted in different environments using different experimental techniques, different measurement

definitions, and different analysis methods.

ISO 15007 has been developed to give guidance on the terms and measurements relating to the collection

and analysis of driver visual behaviour data. This approach aims to assess how drivers respond to vehicle

design, the road environment, or other driver-related tasks in both real and simulated road conditions.

More specifically, the approach of this standard is based on the assumption that efficient processing of

visual information is essential to the performance of the driving task.

ISO 15007-1 defines key terms and parameters applied in the analysis of driver visual behaviour focused

on glance and glance related measurements. ISO 15007-2 gives guidelines on equipment and procedures

for analysis of driver visual behaviour.

Practical assessments of drivers in real or simulated environments are conducted to quantify the

allocation of visual behaviour to specified areas of interest. Visual behaviour may be quantified by the

location, duration and frequency of glances to a specified area of interest in the visual scene (and, over

time, between areas of interest). This approach often uses commonly available eye tracking and/or

video-recording equipment. However, it does not preclude the use of more sophisticated technologies

which may elicit additional driver visual behaviour information.

Results from such assessments should enable comparison of the relative influence of the TICS use with

reference conditions.

Road vehicles — Measurement of driver visual behaviour
with respect to transport information and control systems —
Part 1:
Definitions and parameters
1 Scope

This part of ISO 15007 defines key terms and parameters applied in the analysis of driver visual

behaviour focused on glance and glance-related measures. These terms and parameters can be applied

in environments from real-world driving experiments to laboratory-based driving simulator studies.

The procedures described in this part of ISO 15007 could also apply to more general assessments

of driver visual behaviour without the introduction of TICS-specific systems. The parameters and

definitions described below are intended to assist development of a common source of reference for

driver visual behaviour data.

Minimum requirements for reporting the results of Transport Information and Control Systems (TICS)

evaluations are provided.

Further guidance including the specification of how to analyse and present the results of studies of visual

behaviour is available in other ISO publications (see, for example, ISO 2854 and ISO/TR 13425:2006).

However, data collected and analysed according to this standard will allow comparisons to be performed

across different TICS applications and experimental scenarios.

For the purposes of this document, the following terms and definitions apply.
3.1
accommodation

adjustment of the lens of the eye to bring about focusing of an image of an object upon the retina

Note 1 to entry: The time for the eye to accommodate from one object to another depends on the distance

between the objects.

3.2
adaptation
ability of the eye to adjust to changing light conditions

Note 1 to entry: Adaptation times to transition from dark to light and light to dark are different.

3.3
direction of gaze
area of interest to which the eyes are directed
3.4
fixation

alignment of the eyes so that the image of the fixated area of interest falls on the fovea (the middle of the

retina responsible for our central, sharpest vision) for a given time period
[3]

Note 1 to entry: Typically, individual fixations last from 100 ms to 2 000 ms (see Reference ). Fixations are the

briefest of pauses during which visual information extraction is done by the eyes-and-brain from spatial areas

that fall on the fovea of the eye (and hence are quite small). During fixation, there are believed to be at least three

[10]

processes taking place (see Reference ): 1) analysis of the image falling on the fovea, 2) selection of a new

saccade target and 3) programming of the saccade to-be-made-next. It is not yet known how these processes are

synchronized by the brain, nor how precisely they are synchronized – since fixation durations are not always long

enough to comprehend completion of all the processes. (Sometimes the eyes move before information extraction

from the site of fixation has been completed, as evidenced by frequent corrective return fixations to a site under

some conditions that was fixated too briefly). There is evidence that the brain both pre-programs fixation duration,

and also does “process-monitoring” during a fixation to determine if analysis of the foveal image is complete

within the fixation’s duration.before moving on. Thus, fixation time is dependent on both the immediate stimulus

and the history of prior fixations. The contribution of both components suggests that fixation time may depend

[4]

on the task and the amount of useful information in the fixated display (or viewed information) (see Reference ).

See A.1 to A.4.
3.5
glance

maintaining of visual gaze within an area of interest, bounded by the perimeter of the area of interest;

may be comprised of more than one fixation and saccades to and from it. Its duration is measured as

“glance duration”

Note 1 to entry: A glance is a scientific construct that sums over one or more fixations that are made contiguously

within a given area of interest (but one that is larger than the area corresponding to the eye’s foveal region –

an area that usually requires more than one fixation to view). The construct of a glance, therefore, typically

comprehends more than a single fixation and is a coarser unit of analysis than a single fixation (since it is summing

over fixations that are contiguous in time and spatially proximal within an area of interest). (“Area of interest”
