本文档介绍了认知可访问系统（包括产品、服务和构建环境）的设计和开发指南。 本文件与主流系统以及专门为残疾人设计的系统相关。 在可访问性的广泛领域内，本文件仅限于与认知可访问性相关的指南。 注1:然而，它承认，不同的感官感知可能会影响认知可及性。 注2:虽然本文件中的以下指南可以让所有用户受益，但此处将其包括在内，因为不遵守该指南可能会导致一些潜在用户无法使用该系统的障碍。 本文件适用于所有类型的系统。但是，某些特定建议只能适用于某些类型的系统: -其中一些指南与固定系统有关（例如:。 g、 非计算机化消费产品或用户手册）； -其中一些指南适用于包含某种程度的计算机处理的系统（例如微波炉或ICT系统）； -其中一些指南适用于使用支持个性化的高级计算机处理的系统（例如智能手机中的应用程序）； -一些指南适用于上述组合。

This document presents guidelines for the design and development of cognitively accessible systems, including products and services and built environments. This document is relevant to mainstream systems as well as those designed specifically for people with disability. Within the broad field of accessibility, this document is limited to guidance related to cognitive accessibility. NOTE 1 It acknowledges, however, that diverse sensory perceptions can impact cognitive accessibility. NOTE 2 While the following guidance in this document can benefit all users, it is included here because failure to follow it could lead to barriers that would prevent some potential users from being able to use the system at all. This document is relevant to all types of systems. However, some particular recommendations can only be followed for some types of systems: — Some of the guidance is relevant to a fixed system (e.g. a non-computerized consumer product or a user manual); — Some of the guidance applies to systems containing some level of computer-based processing (e.g. a microwave oven or an ICT-system); — Some of the guidance applies to systems that use advanced computer processing that supports individualization (e.g. an application in a smart phone); — Some guidance applies to combinations of the above.
