Introduction
Cognitive impairment can affect anyone, and the effects may be temporary or permanent. Cognitive impairment can affect a person's.

It is generally believed that mainstream systems are more affordable than rehabilitation assistive devices and have higher social acceptance. Access to mainstream systems is unrestricted, which helps the general public to understand

The knowledge is quite extensive. Designers and manufacturers of mainstream systems understand these needs and help build accessible and functional mainstream systems.

important.
GB/T 42818 aims to specify the design and development requirements for cognitive accessibility systems and is intended to be composed of two parts.
---Part 1.General guidance. The purpose is to provide guidelines for the design and development of cognitively accessible systems.
---Part 2.Report. The purpose is to specify reporting requirements for cognitive accessibility of systems based on the recommendations given in Part 1.
Cognitive Accessibility Part 1.General Guidelines
1 Scope
This document provides guidance for the design and development of cognitively accessible systems, including products, services, and built environments.
This document is relevant to both mainstream systems and systems designed specifically for people with functional impairments.
This document is limited to guidance related to cognitive accessibility.
Note 1.This document recognizes that different sensory perceptions may have an impact on cognitive accessibility.
Note 2.The following guidelines in this document are beneficial to all users. Failure to follow the guidelines may result in some potential users being unable to use the system.
This document is relevant to all types of systems, however, for some types of systems only special recommendations can be followed.
---Some suggestions relate to established systems (such as non-computerized consumer products or user manuals);
---Some recommendations apply to systems that contain a certain level of computer-based processing (such as microwave ovens or ICT systems);
---Some recommendations apply to systems that support personalization and use advanced computer processing (such as applications in smartphones);
---Some suggestions apply to systems that are a combination of the above systems.
