Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

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 ISO documents 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 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 ).

Introduction

Visual displays are in-built in many consumer products to be used to present information about the status, function or operation of the product to the users. If a product is big enough to adopt large displays, it would be easy to make the various users including older or visually disabled people feel comfortable in recognizing and understanding the presented information on the displays. Some small consumer products, such as digital cameras and remote controllers of air conditioners, are equipped with a small display because of the limited space on the product itself. The adoption of small display can mean that many users experience difficulties in using those products because they cannot easily recognize or understand the information visually presented on it. Among the many things that can be done to make the product more accessible to the widest range of users, one thing is to carefully design the visual information presented on the small display. This document provides design guidance on the accessibility of visually presented information on small displays.

1 Scope

This document specifies the methods to improve accessibility of the visual display on small consumer products in order to minimize inconveniences that a variety of users including people with disabilities and the elderly can experience while using those products.

In particular, this document focusses on how to present information on small visual displays to make the product more accessible for older people and people with low vision or colour deficiency. The provision of different modalities or alternative ways of displaying information to make the product more accessible is not covered in this document. This document only covers accessibility with regard to visual presentation of information, not audio or tactile-based display methods.

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.

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.

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.
