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).
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

Introduction
Even if users with visual impairments utilize the same hardware as sighted users, it is possible that
they will prefer to use different gestures, or to perform the same gestures differently from the sighted
users. Sighted users can also perform gestures differently when they lack visual feedback.
Users with visual impairments experience problems in understanding shapes or outlines of gestures
for ICT devices, even though they appear simple to sighted users. The critical problem is basically visual
information and feedback from ICT devices. Therefore, it is necessary to provide special gestures for
users with visual impairments.
Screen readers support their users in identifying and understanding content displayed on a screen
of an ICT device. The information about the content is read back to the users out loud by the screen
readers which might utilize text–to–speech or braille output devices. While sighted users visually scan
and understand the content of the screen, the users with visual impairments utilize screen readers
to understand the content. The screen is generally composed of page regions, headings, navigation
elements, text links, images, etc. It is necessary for users of screen readers to identify the elements and
navigate the pages. Therefore, specially designed gestures of screen readers are required. The gestures
need to be standardized for the users of screen readers.
This document provides a general guidance on the standard gestures for screen readers running on
various ICT devices. The gestures are primarily utilized by the users of screen readers when they
interact with ICT devices. Annex A provides descriptions about specific instances of the gestures for
screen readers.
