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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15005 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 13, Ergonomics applicable to road vehicles. SIST EN ISO 15005:2003

ISO 15005:2002(E) © ISO 2002 – All rights reserved v Introduction This International Standard deals with the ergonomic design of transport information and control systems (TICS) and provides general ergonomic principles for their dialogues, independent of any specific dialogue techniques. The utmost care needs to be taken in the design and installation of TICS equipment in order to ensure that it does not impair the driver’s safe control of the vehicle. This is in recognition of the fact that the driving environment has variable conditions, such as road surface, visibility, weather, ambient lighting and traffic conditions. Dialogue management principles for TICSs are characterized by the need to take into account the following:  TICSs are intended for use in a moving vehicle;  TICSs help functions need to be appropriate to a moving vehicle;  TICS dialogues take place in a constantly changing vehicle environment;  TICS technologies need to be suited to that environment;  TICS dialogues include the driver’s vehicle-control actions in response to the TICS. The driver of a vehicle equipped with a TICS device is responsible for the safety of the vehicle, its occupants and other road users. A dialogue therefore needs to take into account the driver workload as a whole, including the cognitive, perceptual and physical tasks associated with driving, so that there will be no impairment of the safe and effective operation of the vehicle. An important objective is to ensure effective and efficient TICS operation while respecting the in-vehicle environment and recognizing the paramount importance of the primary driving task. In addition to the recommendations and requirements related to the principles it presents, ISO 15005 also gives the conditions for compliance. As the manner in which each dialogue principle is applied will depend on the particular characteristics of the TICS function and the specific dialogue technique used, application examples have been provided. The ultimate beneficiary of this International Standard will be the TICS end-user: the driver of the road vehicle. It is the needs of the driver that have determined the ergonomic requirements included by the developers of ISO 15005.

The principles take into account a range of user characteristics. Therefore, the application of this International Standard to a specific TICS function should take into account the characteristics of the target user population. If controls or displays or both are used for non-TICS functions, these functionalities are excluded from the provisions of this International Standard. 5 Dialogue principles 5.1 General The following principles have been identified as being important in the design and evaluation of a TICS dialogue. a) Appropriate for use while driving:  compatibility with driving;  simplicity;  timing/priorities. SIST EN ISO 15005:2003

ISO 15005:2002(E) © ISO 2002 – All rights reserved 5 b) Appropriate for the TICS task:  consistency;  controllability. c) Appropriate for the driver:  self-descriptiveness;  conformity with driver expectations;  error tolerance. These dialogue principles are explained, and the related requirements and recommendations are given, together with examples demonstrating how the principles can be applied. Wherever there are requirements, compliance verification conditions for these are also given. 5.2 Appropriate for use while driving 5.2.1 Explanation of principle A TICS dialogue is appropriate for use while driving to the extent that it recognizes the paramount importance of the driving task, the driver’s need to respond to stimuli from the traffic environment and, where applicable, from TICS that enhance the driving task. 5.2.2 Compatibility with driving 5.2.2.1 Explanation of principle A TICS dialogue is compatible with driving when the use of the TICS optimizes, or at least does not adversely influence, the driver’s ability to control the vehicle. 5.2.2.2 Requirements 5.2.2.2.1 Whenever a TICS provides inputs to either the primary driving controls or secondary controls, or both, the vehicle’s response to driver operation of these controls shall not be adversely affected. EXAMPLE 1 The driver will be able to override an ACC function by application of the service brake or accelerator. EXAMPLE 2 The driver’s input or braking force will be modified or improved for collision avoidance purposes. A TICS is in compliance with this requirement if a) the TICS has no connection to, or interaction with, either the primary or secondary driving controls or both, or b) the TICS does have such a connection or interaction, but the driver's operations always override the TICS operation. 5.2.2.2.2 TICS dialogues shall not require removal of both hands from the steering wheel while driving. EXAMPLE Hand-held TICS equipment requiring two hands for operation will not be designed for use while driving. A TICS is in compliance with this requirement if it is possible for a driver to perform all TICS control actions while keeping at least one hand on the steering wheel. SIST EN ISO 15005:2003

ISO 15005:2002(E) 6 © ISO 2002 – All rights reserved

5.2.2.2.3 TICS dialogue displays and controls shall be designed and positioned such that both the driving task and the TICS function can be accomplished in an unhindered manner. EXAMPLE 1 TICS displays designed for use by the driver will be positioned and oriented so that they are easily visible, audible or both. EXAMPLE 2 TICS hand controls that are frequently used in conjunction with steering activities (e.g. cruise-control switches) will be positioned within fingertip reach of the steering-wheel rim. EXAMPLE 3 TICS dialogue devices will not block the driver’s direct or indirect view out of the vehicle. A TICS is in compliance with this requirement if a) all TICS controls are located in accordance with the reach requirements of ISO 3958, b) for a TICS device stored in a holster or storage position, at least half of the grasp area is forward of the rearmost driving H-point, c) the TICS is in accordance with the requirements of the applicable auditory presentation standard, d) the TICS visual displays are in accordance with the requirements of ISO 15008, and e) the vehicle with TICS is in accordance with the requirements of SAE J1050. 5.2.2.2.4 TICS functions not intended to be used by the driver while driving (as determined by regulations or by device manufacturers) shall be inaccessible for, or inoperable by, the driver, or both, when the vehicle is in motion. Otherwise, the driver shall be provided with the intended scope of the TICS use, together with suitable warnings. EXAMPLE 1 A typewriter keyboard intended for the driver will be deactivated. EXAMPLE 2 Dynamic images (e.g. television or videogames) other than those related to driving will not be shown. A TICS is in compliance with this requirement if a) TICS functions considered to be inaccessible or inoperable for the driver while driving are inaccessible or inoperable even under reasonably foreseeable and probable misuse, or b) a system, subsystem or menu system is inaccessible for the driver when the means of providing data entry (including the means for switching “on” and “off ”) is either unavailable, disabled, cannot be viewed or found, or has its access for use physically blocked, or c) complex information entry is preceded by advice to use the function only when the vehicle is not in motion, or d) information is provided with the TICS defining intended use. 5.2.3 Simplicity 5.2.3.1 Explanation of principle A TICS dialogue is simple when it limits the amount of information and interaction to the extent necessary for the TICS task. 5.2.3.2 Recommendations 5.2.3.2.1 TICS dialogues affecting vehicle dynamics through control and warning systems should be designed to maximize understanding and facilitate operation. EXAMPLE 1 Since it is assumed that even a naive user of the TICS will have knowledge of vehicle operation, dialogue for information systems will use familiar icons, symbols and text found in other vehicles. SIST EN ISO 15005:2003

ISO 15005:2002(E) © ISO 2002 – All rights reserved 7 EXAMPLE 2 Information that implies distinctive TICS behaviour or requires distinctive driver actions will be presented such that it can be readily distinguished from other (routine) information. EXAMPLE 3 Warning displays will be more conspicuous than, and easily distinguished from, status displays. 5.2.3.2.2 The design of TICS dialogues should optimize physical and mental driver effort and minimize distraction, except where the attraction of the driver’s attention is required.

EXAMPLE 1 Collision avoidance systems use will display by exception principles, i.e. only when a critical situation is sensed by the system will a warning message be displayed to the driver. EXAMPLE 2 Visual displays will be able to detect the ambient illumination and adapt their own brightness accordingly.

EXAMPLE 3 Visual demands of a route guidance function will be minimized by providing spoken, turn-by-turn guidance instructions. EXAMPLE 4 In a dynamic route guidance situation, the guidance information presented on a visual display will be tailored to the driving task: as in a road map for highway travel or an intersection diagram for a turn manœuvre, etc. 5.2.4 Timing/priorities 5.2.4.1 Explanation of principle A TICS dialogue has fulfilled timing and priority requirements for driving when continuous driver attention to traffic situations is supported, or not adversely influenced. 5.2.4.2 Requirements 5.2.4.2.1 A TICS dialogue shall regulate the flow of information into sufficiently short and concise groups that can be easily perceived. EXAMPLE 1 The amount and content of visual information will be limited so that the driver can assimilate it with glances of duration appropriate to the driving situation. EXAMPLE 2 Related pieces of information will be presented in close spatial or temporal proximity to allow the message to be shorter and more easily understood. EXAMPLE 3 The amount of textual driver information will be limited in length. Text on maps will be avoided as much as possible. EXAMPLE 4 Junction representation within a navigation system will be stylized to represent only essential features. A TICS is in compliance with this requirement if a) dwell times of 1,5 s are sufficient to acquire relevant information, and b) the auditory components of a TICS device are in accordanc
