人类工效学.无障碍设计.小型消费品视觉显示信息的无障碍性

[中文适用范围]： 本文件规定了改善小型消费产品视觉显示的可访问性的方法，以尽量减少包括残疾人和老年人在内的各种用户在使用这些产品时可能遇到的不便。 本文档特别关注如何在小型视觉显示器上呈现信息，以使老年人和视力低下或色觉缺陷的人更容易使用该产品。 本文件未涵盖提供不同方式或替代方式显示信息以使产品更易于访问。 本文档仅涵盖信息视觉呈现的可访问性，而不涉及基于音频或触觉的显示方法。 注1：产品的可访问性可以通过采用信息视觉呈现的替代方式来增强，本文件未涵盖这一点。 有关替代表示形式的信息，ISO/IEC Guide 71、ISO 9241-112 和 ISO 9241-171 可能很有用。 注 2：所有用户（不仅是有视力障碍的用户）的无障碍需求和便利策略的综合目录超出了本文件的范围。 对这方面感兴趣的读者可以参考ISO/IEC 29138-1。 本文件适用于配备数字显示器的各种消费产品，其中直观地呈现有关产品操作的信息。 产品通常配备内置显示面板。 消费类产品包括用户可以轻松携带的手持式产品或非便携式但配备小型显示器的产品，尽管本文件中没有指定产品或显示器的尺寸。 注 3：本文档重点关注小型显示器的可访问性，无论消费产品的尺寸如何。 注4：示例包括但不限于电子温度计、数码相机、空调系统、遥控器。 本文件不适用于那些在显示屏上呈现信息具有高度灵活性或可调节性的产品。 一些例子是基于网络或应用程序的 ICT 设备显示，例如智能手机、智能电视和平板电脑。 不适用于兼具显示和控制功能的触摸显示器。 一些例子是智能手表或数码相机的触摸界面。 最后，ISO 24550 中涵盖了与用于简单警报或警报的指示灯/灯相关的可访问性问题，本文件中不予考虑。 注5：触摸界面中存在许多与信息呈现和控制功能相关的可访问性问题，需要一起处理。 本文档的某些指导可能不适用于某些内置显示屏极小的产品，例如口腔温度计或耳温计。 [外文原描述]： 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. NOTE 1 Accessibility of a product can be enhanced by adopting alternative means to the visual presentation of the information, which is not covered in this document. For information about alternative forms of presentation, ISO/IEC Guide 71, ISO 9241‑112 and ISO 9241‑171 can be useful. NOTE 2 A comprehensive catalogue of accessibility needs and strategies for accommodation for all users (not only those with visual impairments) is out of scope for this document. Readers interested in this regard can refer to ISO/IEC 29138‑1. 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. NOTE 3 This document focusses on the accessibility of small displays, regardless of the size of the consumer product. NOTE 4 Examples include, but are not limited to, electronic thermometers, digital cameras, air-conditioning systems, remote controllers. 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. NOTE 5 There are many accessibility issues in the touch interface related to information presentation as well as control function and they need to be dealt with together. 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.
