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

list of patent declarations received (see http:// patents .iec .ch).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

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.
