Information technology — User interface accessibility — Part 3: Requirements and recommendations on user needs mapping
This document provides guidance on the mapping of a set of user accessibility needs with the provisions of a particular standard, technical report, or set of guidelines. It provides both basic guidance that should be used for all user accessibility needs mapping and optional guidance that may be added to the basic guidance. User accessibility needs mapping is intended to help improve accessibility for all users and, in particular, for users with special needs that can be overlooked. User accessibility needs mapping is not intended to be used to evaluate or certify a given standard or set of guidelines.

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.
The procedures used to develop this document and those intended for its further maintenance
are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria
needed for the different types of document should be noted. This document was drafted in
accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or
www.iec.ch/members_experts/refdocs).
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. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents) or the IEC
list of patent declarations received (see https://patents.iec.ch).

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 35, User interfaces.
This first edition of ISO/IEC 29138-3 cancels and replaces ISO/IEC TR 29138-3:2009.
The main changes are as follows:
— The document has been renamed to fit into the revised ISO/IEC 29138 series;
— The document has been revised from being a Technical Report to an International Standard by the
addition of requirements and recommendations;
— A second format for the mapping has been added.

Introduction
The user accessibility needs specified in ISO/IEC 29138-1 can be mapped to existing and developing
standards to identify for which user accessibility needs the standard provides guidance. Mappings,
as specified in this document, can help standards developers to consider the potential for addressing
particular needs in their standards. Mappings can be included as informative annexes within standards
to help developers to find guidance in addressing particular user accessibility needs within the
standard. Compilations of mappings can help developers to identify standards containing guidance
addressing particular user accessibility needs.
Some standards cover limited domains, and in such cases, some user accessibility needs do not apply.
For example, visual accessibility needs are generally not relevant to standards addressing the ability
to exert force. Standardization organizations can selectively use the set of user accessibility needs for
their own purposes.

Information technology — User interface accessibility —
Part 3:
Requirements and recommendations on user needs
mapping
1 Scope
This document provides guidance on the mapping of a set of user accessibility needs with the provisions
of a particular standard, technical report, or set of guidelines. It provides both basic guidance that
should be used for all user accessibility needs mapping and optional guidance that may be added to the
basic guidance.
User accessibility needs mapping is intended to help improve accessibility for all users and, in particular,
for users with special needs that can be overlooked. User accessibility needs mapping is not intended to
be used to evaluate or certify a given standard or set of guidelines.

4 Benefits of user accessibility needs mapping
User accessibility needs mapping benefits standards developers and developers of style guides by:
— alerting them to the range of user accessibility needs,
— helping them to identify the user accessibility needs dealt with by their standards,
— helping them to identify standards materials that address particular user accessibility needs, where
mappings exist for these other standards,
— helping them to identify where additional guidance can be added to their standards to deal with
further user accessibility needs.
User accessibility needs mapping benefits end users by encouraging their needs to be considered
by standards (and similar documents) and the developer's products and services who apply these
standards (and similar documents).

User accessibility needs mapping to standards can also benefit policy makers and accessibility
advocates by helping them to identify standards materials that address specific needs.
User accessibility needs mapping benefits ISO/IEC JTC1 by providing information on the accessibility
related provisions of different standards. This information can be used:
— to provide information on the set of existing standards that deal with various accessibility concerns,
— to identify the potential for new standards to deal with additional accessibility concerns.
5 Mapping individual requirements and recommendations
5.1 Mapping user accessibility needs with guidelines in standards
Mapping identifies guidelines in a standard that relate to specific user accessibility needs.
NOTE User accessibility needs categories are not normally mapped.
It is possible that:
— a single guideline maps to a single user accessibility need;
— multiple guidelines map to a single user accessibility need;
— a single guideline maps to multiple user accessibility needs;
— a guideline leads to the identification of a new user accessibility need.
It is important to ensure that mapping is done completely and does not miss any possible mappings.
Mapping can be performed by:
a) dealing with each specific user accessibility need, one need at a time, in the order that user
accessibility needs occur in the list of user accessibility needs;
b) dealing with each specific requirement and recommendation in the standard being mapped;
c) a combination of these two approaches, as long as care is taken to ensure that all requirements and
recommendations are mapped.
5.2 Persons performing user accessibility needs mapping
While user accessibility needs mapping can be performed by anyone, it is preferable that it be performed
by someone with considerable expertise in the standard being mapped.
5.3 Set of user accessibility needs
This document makes use of the set of user accessibility needs in ISO/IEC 29138-1.
It is intended that the approach described in this document will also work with future versions of
ISO/IEC 29138-1.
If persons performing user accessibility needs mapping identify additional potential user accessibility
needs, they can add those needs to their mapping and are asked to provide a copy of their completed
mapping to their national standards body for submission to the Secretariat of ISO/IEC JTC1/SC35 so
that the additional potential user accessibility needs can be considered for addition to future versions
of ISO/IEC 29138-1.
