of 21 December 1999

on safe and efficient in-vehicle information and communication systems: A European statement of
principles on human machine interface

(notified under document number C(1999) 4786)

(Text with EEA relevance)

(2000/53/EC)

THE COMMISSION OF THE EUROPEAN COMMUNITIES,

Having regard to the Treaty establishing the European Community, and in particular Article 211 thereof,

(1) Whereas the importance of a safe human machine interface (HMI) for in-vehicle information and
communication systems has been stressed many times in resolutions, conclusions and opinions of
several European Institutions such as the Council Conclusions of 17 June 1997, the European
Parliament Resolution of 8 October 1998 and the Opinion of the Committee of the Regions of 14
May 1998 (1) on Commission Communication COM(97) 223 of 20 May 1997 related to a
Community strategy and framework for the deployment of road transport telematics in Europe; the
in
Council Resolution of 17 June 1997 on the development of telematics in road transport,
particular with respect to electronic fee collection (2);

(2) Whereas a basis for consumer protection is given by Council Directive 92/59/EEC of 29 June 1992
on general product safety (3) and the Council Resolution of 17 December 1998 on operating
instructions for technical consumer goods (4) but is not specific enough in particular in the present
field;

(3) Whereas telematics devices inside vehicles will have an important impact on road transport in the
near future and will provide valuable assistance to the driver under the condition that the driver is
not distracted, disturbed or overloaded by the communication process and/or the information
provided by the additional devices;

(4) Whereas the market opportunities for industry and added value service providers should not be
inhibited unnecessarily and the development of future safe innovative products in the field of
automotive information and telecommunication technologies should be encouraged;

(5) Whereas principles should be set up to be followed on a voluntary basis by the relevant market

players;

(6) Whereas a general safety requirement needs to be established for products in order to lift barriers to

trade within the internal market;

(7) Whereas a European statement of principles on the human machine interface of in-vehicle informa-
tion and communication systems is essential to maximise their safety potential; whereas this
statement of principles should fully take into account earlier work done in the framework of other
international organisations such as the European Conference of Ministers of Transport and United
Nations;

(8) Whereas further work is being carried out by the Commission on the expansion of the principles,
explaining in more detail each principle, describing the rationale and giving good and bad examples
whenever necessary as well as on their verification procedures, whenever possible; whereas a report
on the expansion of principles will be presented by the end of 1999;

(9) Whereas the Commission services are going to collect information from the Member States on the
steps taken and the evaluation results about the adherence to these principles by industry and
undertake if necessary additional

investigations;

(10) Whereas after an initial period of two years and depending on the adherence to the statement of
principles on human machine interface for in-vehicle information and communication systems, the
Commission will consider the necessity of additional actions such as adaptation of Directive
92/53/EEC of 18 June 1992 on the approximation of the laws of the Member States relating to the
type approval of motor vehicles and their trailers (1) or introduction of a supplementary directive,
using CEN/ISO standards;

(11) Whereas the requirements cited above cannot be achieved on national

level,

MAKES THE FOLLOWING RECOMMENDATION:

1. The European motor manufacturing and supply industries which provide and/or fit and/or design
in-vehicle information and communication systems, whether original equipment providers or after sales
system providers, including importers, should comply with the attached statement of principles and are
invited to enter into a voluntary agreement on this matter. This statement of principles summarises
essential safety aspects to be taken into account for the human machine interface (HMI) for in-vehicle
information and communication systems and is concerned with all these systems intended for use by the
driver while driving. In this context the principles consider that the driver's primary driving task is safely
controlling the vehicle through a complex dynamic traffic environment.

These principles are valid:

— whether the system is directly related to the driving task or not

— for both portable and permanently installed systems such as telephones

— for both original equipment manufacturers and after sales system providers including importers for

all road vehicle types provided on the Community market.

2. Member States are invited to encourage industry to adhere to this statement of principles and to

investigate the adherence to these principles by industry,

including after sales system providers.

3. Member States should inform the Commission within a period of 12 months from publication of this
recommendation of the steps taken by them and by their industries and should provide evaluation
results within a period of 24 months about the adherence to these principles by industry.

Done at Brussels, 21 December 1999.

STATEMENT OF PRINCIPLES ON HUMAN MACHINE INTERFACE (HMI) FOR IN-VEHICLE INFORMATION
AND COMMUNICATION SYSTEMS

ANNEX

1. Definition of objectives

This statement of principles summarises essential safety aspects to be taken into account for the human machine interface
(HMI) for in-vehicle information and communication systems.

This statement of principles will be of particular use to manfuacturers when they have to consider the safety implications
of HMI design. Desgin and installation issues are the main concern of this statement of principles and they therefore relate
to the following critical

issues:

— how to design and locate information and communication systems in such a way that their use is compatible with the

driving task

— how to present information so as not to impair the drivers's visual allocation to the road scene

— how to design such system interaction that the driver maintains under all circumstances safe control of the vehicle,
feels comfortable and confident with the system and is ready to respond safely to unexpected occurrences.

In order not to create unnecessary obstacles or constraints to the innovative development of products, the statement of
principle is expressed mainly in terms of the goals to be reached by the HMI.

2. Scope

This statement of principles is concerned with all information and communication systems intended for use by the driver
while driving. In this context the principles consider that the driver's primary driving task is safely controlling the vehicle
through a complex dynamic traffic environment.

For the purpose of this statement of principles ‘the system’ refers to the functions and parts, such as displays and controls,
that constitute the interface and interaction between the system and the driver.

These principles have been formulated to consider the design and installation of individual systems. Where more than one
system is present within a vehicle they should ideally be presented as an integrated driver interface where the complete
installation also complies with this statement of principles.

The main topics of this statement of principles are overall design, installation, information presentation, interaction with
displays and controls, system behaviour and information about the system.

The statement of principles does not cover aspects of information and communication systems not related to HMI such as
electrical characteristics, material properties, system performance and legal aspects.

3. Existing provisions

This statement of principles is not a substitute for regulations and standards and these should always be respected and
used by manufacturers.

— Applicable EC Directives with their subsequent amendments include:

— on the field of vision of motor vehicle drivers:

Commission Directive 90/630/EEC of 30 October 1990 (1);

— the interior fittings of motor vehicles (interior parts of the passenger compartment other than the interior

rear-view mirrors,
Council Directive 74/60/EEC of 17 December 1973 (2);

layout of controls, the roof or sliding roof, the backrest and rear part of seats):

— the interior fittings of motor vehicles (identification of controls, tell tales and indicators):

Council Directive 78/316/EEC of 21 December 1977 (3).

— Council Resolution of 17 December 1998 (4) on operating instructions for technical consumer goods

— Council Directive 92/59/EEC of 29 June 1992 on general product safety (5)

— Economic Committee for Europe (UN/ECE) regulations which are recognised by the Community after its recent

adhesion to the Revised Agreement of 1958

— Standards and standard documents in preparation implicitly referred to in the principles are:

— ISO 4513 Road vehicles — Visibility. Method for establishment of eyellipse for driver's eye location

— ISO 2575 Road vehicles — Symbols for controls,

indicators and tell-tales

— ISO 4040 Road vehicles — Location of hand controls,

indicators and tell-tales

— ISO 3958 Road vehicles — Passenger car driver hand control reach

— ISO (DIS) 15005 Road vehicles — Traffic information and control systems (TICS) dialogue management principles

— ISO (DIS) 15006 Road vehicles — Traffic information and control systems (TICS) auditory presentation of

information

— ISO (DIS) 15008 Road vehicles — Traffic information and control systems (TICS) ergonomic aspects of in-vehicle

information presentation

— ISO (DIS) 11429 Ergonomics — System danger and non-danger signals with sounds and lights.

All standards are subject to revision, and users of this statement of principles should apply the most recent editions of the
standards indicated here.

Generally, it will be clear where the responsibility lies, among manufacturers, suppliers and installers, of applying the
principles. Where the responsibility rests with more than one party, those parties are encouraged to use the principles as a
starting point to explicitly confirm their respective roles.

The responsibilities of the driver related to safe behaviour while driving and interacting with these systems remain
unchanged.

4. Overall design principles

The system should be designed to support the driver and should not give rise to potentially hazardous behaviour by the
driver or other road users.

The system should be designed in such a way so that the allocation of driver attention to the system displays or controls
remain compatible with the attentional demand of the driving situation.

The system should be designed so as not to distract or visually entertain the driver.

5.

Installation principles

The system should be located and fitted in accordance with relevant regulations, standards and manufacturers instructions
for installing the system in vehicles.

No part of the system should obstruct the driver's view of the road scene.

The system should not obstruct vehicle controls and displays required for the primary driving task.

Visual displays should be positioned as close as practicable to the driver's normal

line of sight.

Visual displays should be designed and installed to avoid glare and reflections.

6.

Information presentation principles

Visually displayed information should be such that the driver can assimilate it with a few glances which are brief enough
not to adversely affect driving.

Where available, internationally agreed standards relating to legibility, audibility, icons, symbols, words, acronyms or
abbreviations should be used.

Information relevant to the driving task should be timely and accurate.

The system should not present information, which may result in potentially hazardous behaviour by the driver or other
road users.

The system should not produce uncontrollable sound levels liable to mask warnings from within the vehicle or outside.

7. Principles on interaction with displays and controls

The driver should always be able to keep at least one hand on the steering wheel while interacting with the system.

Speech based communications systems should include provision for hands-free speaking and listening.

The system should not require long and uninterruptable sequences of interactions.

System controls should be designed such that they can be operated without adverse impact on the primary driving task.

The driver should be able to control the pace of interaction with the system.

The system should not require the driver to make time-critical responses when providing input to the system.

The driver should be able to resume an interrupted sequence of interactions with the system at the point of interruption
or at another logical point.

The driver should have control of auditory information where there is a likelihood of distraction or irritation.

The system's response (e.g. feedback, confirmation) following driver input should be timely and clearly perceptible.

Systems providing non-safety-related dynamic visual information should be capable of being switched into a mode where
that information is not provided to the driver.

8. System behaviour principles

Visual information not related to driving that is likely to distract the driver significantly (e.g. TV, video and automatically
scrolling images and text) should be disabled or should only be presented in such a way that the driver cannot see it while
the vehicle is in motion.

The presence, operation or use of a system should not adversely interfere with displays or controls required for the
primary driving task and for road safety.

System functions not intended to be used by the driver while driving should be made impossible to interact with while
the vehicle is in motion, or clear warnings should be provided against the unintended use.

Information about current status, and any malfunction, within the system that is likely to have an impact on safety should
be presented to the driver.

In the event of a partial or total failure of the system, the vehicle should remain controllable, or at least should be capable
of being brought to a halt in a safe manner.

9. Principles on information about the system

The system should have adequate instructions for the driver covering use and relevant aspects of installation and
maintenance.

System instructions should be correct and simple.

System instructions should be in language or form designed to be understood by the driver.

The instructions should clearly distinguish between those aspects of the system which are intended for use by the driver
while driving and those aspects (e.g. specific functions, menus etc) which are not intended to be used while driving.

All product information should be designed to convey accurately the system functionality.

Product information should make it clear if special skills are required to use the system or if the product is unsuitable for
particular users.

Representations of system use (e.g. descriptions, photographs and sketches) should neither create unrealistic expectations
on the part of potential users nor encourage unsafe or illegal use.
