Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
In exceptional circumstances, the joint technical committee may propose the publication of a Technical Report
of one of the following types:
⎯ type 1, when the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts;
⎯ type 2, when the subject is still under technical development or where for any other reason there is the
future but not immediate possibility of an agreement on an International Standard;
⎯ type 3, when the joint technical committee has collected data of a different kind from that which is
normally published as an International Standard (“state of the art”, for example).
Technical Reports of types 1 and 2 are subject to review within three years of publication, to decide whether
they can be transformed into International Standards. Technical Reports of type 3 do not necessarily have to
be reviewed until the data they provide are considered to be no longer valid or useful.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC TR 29138-2, which is a Technical Report of type 3, was prepared by Joint Technical Committee
ISO/IEC JTC 1, Information technology.
ISO/IEC TR 29138 consists of the following parts, under the general title Information technology —
Accessibility considerations for people with disabilities:
⎯ Part 1: User needs summary
⎯ Part 2: Standards inventory
⎯ Part 3: Guidance on user needs mapping

Introduction
ISO/IEC JTC 1 believes that the work in the area of information communication technology (ICT)
standardization for accessibility is a major undertaking, encompassing many global, regional and local
interests. Additionally, there are significant standards efforts taking place in ISO, IEC, ITU and the national
and regional standards bodies as well as various consortia/fora and user groups.
This Technical Report identifies sources of ICT accessibility guidance to support users with the widest range
of capabilities. The number of people using ICT products and services, which combine hardware, software,
and network technologies, is increasing, as is the variety of ICT products and services. Our everyday lives are
filled with such products and services. Currently available ICT equipment and services, however, are not
always accessible. Typically, the people most excluded by poor accessibility of products and services are
those with disabilities and those with limitations due to age. However, they are not the only ones who
experience difficulty in operating ICT products, such as personal computers (PCs). It is essential to improve
ICT accessibility so that people with such special needs can have access to ICT products and services. The
improvement of accessibility of products and services benefits all users, not only people with such special
needs, leading to an inclusive e-society.
By providing appropriate ICT accessibility standards, the market of accessible ICT products and services will
develop more efficiently and effectively. Standardization encourages organizations to address the needs of
the people with disabilities and people with limitations due to age and triggers development of ICT products
and services with built in accessibility.
Standardization bodies are starting to address disability and age-related issues and will, increasingly, develop
and implement policies and programs in their standards development to include the needs of both people with
disabilities and people with limitations due to age. Individuals have different access needs because of their
different levels of capabilities and disabilities. Particularly people with multiple disabilities have distinct needs.
The great variety and distinctiveness of individual differences make it difficult for individual standards to
address all the needs which address the widest range of capabilities and disabilities.

TECHNICAL REPORT ISO/IEC TR 29138-2:2009(E)

Information technology — Accessibility considerations for
people with disabilities —
Part 2:
Standards inventory
1 Scope
This part of ISO/IEC TR 29138 identifies a collection of documents (which it refers to as standards even
though they encompass more than traditional ISO and ISO/IEC standards) that provides guidance on meeting
the needs of people with disabilities. While its primary audience is standards developers, it can also be helpful
for developers of information technology products and services, policy makers, procurers and for accessibility
advocates to consider.
In addition to identifying user needs, this part of ISO/IEC TR 29138 identifies problems that people with
disabilities experience with Information Technologies that lead to these user needs and identifies the
relationship of these user needs with the accessibility factors for standards developers to consider found in
ISO/IEC Guide 71: Guidelines to address the needs of older persons and people with disabilities when
developing standards.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
standard
identifiable document that contains some specific guidance
NOTE In the context of this part of ISO/IEC TR 29138, document standards include: all ISO and ISO/IEC standards,
technical reports, publicly available specifications and all documents of other organizations that have a similar function to
these ISO and ISO/IEC documents.
2.2
user
person who interacts with the product, service or environment
NOTE Adapted from ISO/IEC Guide 71 definition 3.4, which is adapted from ISO 9241-11:1998.
2.3
user accessibility need
user need
requirement of a product or its environment of use that improves accessibility to the system for users whose
abilities are reduced through environmental factors, injury, disability, or natural degradation from aging
NOTE 1 Where there are many other types of user needs, this Technical Report only deals with user accessibility
needs and thus uses the shorter form "user need" to refer to user accessibility needs.
NOTE 2 It might not be possible to meet all user needs.

3 Standards categories
There are many possible means of organizing the set of standards identified in this part of ISO/IEC TR 29138.
The approach taken here is to categorize them in terms of their breadth of application. This organization does
not provide mutually exclusive categories, but rather categories that can be added together to provide
increasingly detailed guidance.
a) High-level standards (clause 4.1) are the most generally applicable standards. In addition to collections
of guidance from multiple categories, this category also includes standards providing general guidance
and those providing guidance on design.
NOTE Because of their composition, standards listed in clause 4.1 can also be considered as belonging to all
other categories.
b) Hardware/equipment-oriented standards (clause 4.2) apply to all types of computer hardware and to
most types of related equipment, including consumer electronics, communication equipment, and
computers and related equipment designed for use in specialized environments.
NOTE 1 Additional standards applying to specialized environments are listed in clause 4.5.
NOTE 2 Additional standards applying to communications services are listed in cl
