This document specifies different methods for the determination of metabolic rate in the context of
ergonomics of the thermal working environment. It can also be used for other applications, e.g. the
assessment of working practices, the energetic cost of specific jobs or sport activities and the total
energy cost of an activity. The methods are classified in four levels of increasing accuracy: level 1,
Screening, with a table giving examples of activities with low, moderate and high metabolic rates; level
2, Observation, where the metabolic rate is estimated by a time and motion study; level 3, Analysis,
where the metabolic rate is estimated from heart rate recordings or accelerometers measurements;
and level 4, Expertise, where more sophisticated techniques are described. The procedure to put into
practice these methods is presented and the uncertainties are discussed.

This document provides guidance on the design, selection and optimization of non-contacting hand and arm gestures for human-computer interaction. It addresses the assessment of usability and fatigue associated with different gesture set designs and provides recommendations for approaches to evaluating the design and selection of gestures. This document also provides guidance on the documentation of the process for selecting gesture sets. This document applies to gestures expressed by humans. It does not consider the technology for detecting gestures or the system response when interpreting a gesture. Non-contacting hand gestures can be used for input in a variety of settings, including the workplace or in public settings and when using fixed screens, mobile, virtual reality, augmented reality or mixed-mode reality devices. Some limitations of this document are: —   The scope is limited to non-contacting gestures and does not include other forms of inputs. For example, combining gesture with speech, gaze or head position can reduce input error, but these combinations are not considered here. —   The scope is limited to non-contacting arm, hand and finger gestures, either unilateral (one-handed) or bilateral (two-handed). —   The scope assumes that all technological constraints are surmountable. Therefore, there is no consideration of technological limitations with interpreting ultra-rapid gestures, gestures performed by people of different skin tones or wearing different colours or patterns of clothing. —   The scope is limited to UI-based command-and-control human computer interaction (HCI) tasks and does not include gaming scenarios, although the traversal of in-game menus and navigation of UI elements is within scope. —   The scope does not include HCI tasks for which an obviously more optimal input method exists. For example, speech input is superior for inputting text than gesture input. —   The scope includes virtual reality (VR), augmented reality (AR) and mixed reality (MR) and the use of head-mounted displays (HMDs). —   The scope does not include the discoverability of gestures but does include the learnability and memorability of gestures. It is assumed that product documentation and tutorials will adequately educate end users about which gestures are possible. Therefore, assessing gesture discoverability is not a primary goal of the recommendations in this document.

This document establishes an ergonomic model for any cyclical human work planned and executed in an industrial competitive environment. It also covers the process of measuring work based on the concept of normal work performance and of the assessment of risk factors commonly associated with body postures, body or hand forces, manual material handling of loads and handling low loads at high frequency. This document applies to the adult working population and is intended to give reasonable protection for nearly all healthy adults. Those areas concerning health risks and control measures are mainly based on experimental studies regarding musculoskeletal loading, discomfort or pain and endurance or fatigue related to work organization and methods. The scope of this document is any cyclical human work planned and executed in an industrial competitive environment. The most typical cases are within industries where there is the need to define an expected output (products or services) based on the optimization of the trade-off between labour productivity and health and safety. The most sensitive organizations to this proposal are those within labour-intensive manufacturing industries with series and batch production systems: —   automotive (original equipment manufacturer and tier 1 and 2 suppliers); —   industrial automotive (trucks, buses, agricultural and mining equipment); —   industrial manufacturing (small domestic and industrial equipment or machinery); —   domestic appliances and consumer goods (white goods); —   plastic and rubber products (tires, doors, windows, shoes); —   consumer electronics (PCs, televisions, printers, radios, hi-fis, alarm systems); —   furniture; —   textiles and apparel; —   food preparation; —   packaging; —   aerospace and defence; —   rail and shipping; —   large domestic and industrial equipment or machinery; —   logistics.

IEC/PAS 62883:2014(E) specifies a framework for adaptive handling of explicit interaction among humans and AAL spaces. This is based on a differentiation between explicit and implicit interaction as a consequence of the paradigm shift from Human-Computer Interaction to Human-Environment Interaction, further explained in the definition of the latter term. As a framework, a main subject matter of the specification is the identification of relevant areas for further standardization, thereby also looking at the interrelationships among the identified areas. The PAS also provides a first extensible specification in some of those areas.

This document provides a framework and consistent terminology for specifying user requirements. It specifies the common industry format (CIF) for a user requirement specification including the content elements and the format for stating those requirements.
NOTE 1 A user requirements specification is the formal documentation of a set of user requirements, which aids in the development and evaluation of usable interactive systems.
In this document, user requirements refers to:
a) user-system interaction requirements for achieving intended outcomes (including requirements for system outputs and their attributes);
b) use-related quality requirements that specify the quality criteria associated with the outcomes of users interacting with the interactive system and can be used as criteria for system acceptance.
NOTE 2 ISO/IEC 25030 introduces the concept of quality requirements. The use-related quality requirements in this document are a particular type of quality requirement.
The content elements of a user requirements specification are intended to be used as part of documentation resulting from the activities specified in ISO 9241-210, and from human centred design processes, such as those in ISO 9241-220.
This document is intended to be used by requirements engineers, business analysts, product managers, product owners, and people acquiring systems from third parties.
The CIF series of standards addresses usability-related information (as described in ISO 9241-11 and ISO/IEC TR 25060).
NOTE 3 In addition to usability, user requirements can include other perspectives, such as human-centred quality introduced in ISO 9241-220, and other quality perspectives presented in ISO/IEC 25010, ISO/IEC TS 25011, and ISO/IEC 25030.
NOTE 4 While this document was developed for interactive systems, the guidance can also be applied in other domains.
This document does not prescribe any kind of method, lifecycle or process. The content elements of a user requirements specification can be used in iterative development which includes the elaboration and evolution of requirements (e.g. as in agile development).

This document addresses: — physically embodied RIA systems, such as robots and autonomous vehicles with which users will physically interact; — systems embedded within the physical environment with which users do not consciously interact, but which collect data and/or modify the environment within which people live or work such as smart building and, mood-detection; — intelligent software tools and agents with which users actively interact through some form of user interface; — intelligent software agents which act without active user input to modify or tailor the systems to the user's behaviour, task or some other purpose, including providing context specific content/information, tailoring adverts to a user based on information about them, user interfaces that adapt to the cognitive or physiological state, "ambient intelligence"; — the effect on users resulting from the combined interaction of several RIA systems such as conflicting behaviours between the RIA systems under the same circumstances; — the complex system-of-systems and sociotechnical impacts of the use of RIA systems, particularly on society and government. This document is not an exploration of the philosophical, ethical or political issues surrounding robotics, artificial intelligence, machine learning, and intelligent machines or environments. For matters of ethics and political issues, see standards such as BS 8611 and IEC P7000. However, this document does identify where and why ethical issues need to be taken into account for a wide range of systems and contexts, and as such it provides information relevant to the broader debate regarding RIA systems. This document has a broader focus than much of the early work on autonomy that relates to the automation of control tasks and mechanization of repetitive physical or cognitive tasks, and centres on levels of automation. Although this document addresses a wide range of technology applications, and sector and stakeholder views on the issues, the treatment of each can be incomplete due to the diverse and increasingly varied applications of RIA systems.

NOTE 2 A comprehensive catalogue of accessibility needs and strategies for accommodation for all users (not only those with visual impairments) is out of scope for this document. Readers interested in this regard can refer to ISO/IEC 29138‑1. This document applies to various consumer products equipped with digital displays, in which the information about operation of the product is visually presented. The products are usually equipped with built-in display panels. The consumer products include those hand-held products that can be easily carried by the user or those that are not portable but equipped with small displays, though the size of the product or the display is not specified in this document. NOTE 3 This document focusses on the accessibility of small displays, regardless of the size of the consumer product. NOTE 4 Examples include, but are not limited to, electronic thermometers, digital cameras, air-conditioning systems, remote controllers. This document is not applicable to those products with high flexibility or adjustability in presenting information on the display. Some examples are web- or application-based displays of ICT devices such as smart phones, smart TVs, and tablet PCs. It is not applicable to touch-based displays that have both the functions of display and control. Some examples are touch interfaces of smart watches or digital cameras. Finally, accessibility issues relating to indicating lamps/lights used for simple alerts or alarm are covered in ISO 24550 and are not considered in this document. NOTE 5 There are many accessibility issues in the touch interface related to information presentation as well as control function and they need to be dealt with together. It is possible that some guidance of this document is not applicable to some products, such as oral or ear thermometers, which have extremely small in-built displays.

This document defines design principles of accessibility for controls of consumer products, so that users from a population with the widest range of user needs, characteristics and capabilities are able to use controls to operate and control consumer products in the same manner and ease as users without disabilities. This document is applicable to all kinds and types of consumer products. This document is applicable to the controls for common main operations of consumer products such as initiation, termination, and cancellation of operation, as well as for specified functions necessary for more detailed operations and fine adjustment. This document does not deal with controls for some specialized devices intended only for specified user populations and tasks, e.g. assistive and medical devices. Each design consideration in this document is based on ergonomic principles that are necessary for making the controls of consumer products accessible to a wider range of users.

EN-ISO 10551 presents principles and examples of practical application for the construction of appropriate subjective scales for use in the assessment and evaluation of the physical environment. It does not standardize particular scales. It considers scales of perception, comfort, preference, acceptability, expression form and tolerance, and environmental components such as thermal, visual, air quality, acoustic and vibration. It does not consider other scales such as: - scales related to the effects of the environment on the ability to read displays or signs, on manual performance or on psychological conditions such as mood, etc.; - scales related to pain or scales related to stimuli that can lead to injury. This document does not present principles of surveys (see Note) or questionnaire design. However, the scales that are developed using this document can be incorporated into surveys or questionnaires.

This standard provides requirements and recommendations for human-centred design principles and activities throughout the life cycle of computer-based interactive systems. It is intended to be used by those managing design processes, and is concerned with ways in which both hardware and software components of interactive systems can enhance human-system interaction.This document provides an overview of human-centred design activities. It does not provide detailed coverage of the methods and techniques required for human-centred design, nor does it address health or safety aspects in detail. Although it addresses the planning and management of human-centred design, it does not address all aspects of project management. The information in this document is intended for use by those responsible for planning and managing projects that design and develop interactive systems. It therefore addresses technical human factors and ergonomics issues only to the extent necessary to allow such individuals to understand their relevance and importance in the design process as a whole. It also provides a framework for human factors and usability professionals involved in human-centred design. Detailed human factors/ergonomics, usability and accessibility issues are dealt with more fully in a number of standards including other parts of ISO 9241 (see Annex A) and ISO 6385, which sets out the broad principles of ergonomics. The requirements and recommendations in this document can benefit all parties involved in human-centred design and development. Annex B provides a checklist that can be used to support claims of conformance with this document.

This document provides guidance for the auditory presentation of information controlled by software, irrespective of the device. It includes specific properties such as the syntactic or semantic aspects of information, e.g. coding techniques, and gives provisions for the organization of information taking account of human perception and memory capabilities. This document does not address the hardware issues of the transmission and the production of auditory information. NOTE 1 Volume is dependent on hardware and thus cannot always be absolutely controlled by software. Environmental conditions can also affect the ability for sounds to be perceived, which can be beyond the ability of the software to take into account. This document does not apply to auditory alarms, warnings or other safety-related uses of auditory information. NOTE 2 Safety-related uses of auditory presentation of information are covered in various domain specific standards, such as ISO 7731:2003 which deals with auditory danger signals for public and work areas, and IEC 60601-1-8:2006 which provides very specific requirements for auditory alarms for medical devices. While this document applies to the presentation of all non-safety-related information, it does not include application domain specific guidance (e.g., audio instructions for consumer products). This document can be utilized throughout the design process (e.g. as specification and guidance for designers during design or as a basis for heuristic evaluation). Its provisions for the presentation of information depend on the auditory design approach, the task, the user, the environment and the single or multiple technologies that can be used for presenting the information. Consequently, this document cannot be applied without knowledge of the context of use. It is not intended to be used as a prescriptive set of rules to be applied in its entirety but rather assumes that the designer has proper information available concerning task and user requirements and understands the use of available technology. This document does not address visual or tactile/haptic presentation of information or modality shifting for the presentation of auditory information in other modalities. NOTE 3 ISO 9241-112 provides high-level ergonomic guidance that applies to all modalities.

This International Standard specifies the processes by which human-centred design is achieved throughout the lifecycle of interactive systems (including products and services). It is also applicable to some noninteractive products, systems or environments intended for human use. These human-centred process (HCP) descriptions are for use in the specification, assessment and improvement of HCPs used in system development and operation. They can also provide the basis for professional development and certification.
The processes support achievement of the overall objective of human-centred design when using a system: usability, accessibility, freedom from risk related to or arising from human use, and user experience (referred to as value-in-use).
NOTE 1 Human-centred design aims to make interactive systems more usable with potential benefits including improved productivity, enhanced user well-being, avoidance of stress, increased accessibility and reduced risk of harm. Ergonomics shares these objectives but is used beyond the domain of design, for example in the forensic analysis of the causes of accidents and in the generation of data and methods of measurement.
The description of processes in this International Standard provides a basis for those planning and carrying out human-centred design activities within an organization, and in the execution of projects. In addition it can provide the basis for those who wish to improve the performance of human-centred design activities within their own organization or in an organization supplying systems or services.
The guidance in this International Standard is not applicable to an organizational re-design, although its application might identify the necessity for re-design.
NOTE 2 ISO 9241-2 and ISO TS 18152 address organizational design in more detail.
This International Standard does not prescribe specific methods. The processes described in ISO 9241-220, can be implemented using a range of methods (such as those described in ISO/TR 16982).
ISO 9241-210 specifies the approaches to human-centred design to be used by project managers, while this International Standard is intended to be used by those performing and supporting human-centred design. These processes can be implemented according to the needs of the specific project and/or organization.
This International Standard specifies the purposes, outcomes, activities and work products for each process. Cross references are made to other parts of the ISO 9241 series that address the design and/or evaluation of components of an interactive system or its environment (see normative Annex B).

This document gives minimum safety, ergonomic, and performance requirements for Camera Monitor Systems to replace mandatory inside and outside rearview mirrors for road vehicles (e.g. classes I to IV as defined in UN Regulation No. 46). It addresses Camera Monitor Systems (CMS) that will be used in road vehicles to present the required outside information of a specific field of view inside the vehicle. These specifications are intended to be independent of different camera and display technologies unless otherwise stated explicitly. Advanced driver assistance systems (ADAS), such as parking aids, are not part of this document. NOTE 1 Mirror classes V and VI (as defined in UN Regulation No. 46) are not in scope of this document since the requirements are already defined in UN Regulation No. 46. NOTE 2 The definitions and requirements in this document are formulated with regard to a system structure, where one camera captures one legally prescribed field of view and one monitor displays one legally prescribed field of view. Of course, also other system structures (e.g. with one monitor displaying two legally prescribed fields of view) are within the scope of this document. For those systems, either the system supplier or the vehicle manufacturer has to prove that the resulting system fulfils the requirements given in Clause 6. NOTE 3 Whenever the phrases "field of view" or "field of vision" are used, then both have the same meaning and are to be used in parallel.
