41 guidance statements support this functional need:
- Appropriate safety level - People may need the system to provide an appropriate level of safety (including physical safety, and safety of my data, finances, legally, etc.).
- Assistive technology-compatible - For systems with user interfaces, people may need content and operable elements to be accessed and presented through assistive technology.
- Background noise - For systems that present content, people may need to be able to distinguish information in the foreground from background noise (noise which may be of any modality).
- Change to cultural conventions, words, and symbols - For systems that present text and images, people may need to change input and user interface components to use text or symbols with which they familiar.
- Characters and punctuation - For systems that include language based content, people may need the characters, symbols, and punctuation required to understand ambiguous words and phrases.
- Clear control behavior - For systems that include interactive components, people may need to understand what a control does, how it relates to other content, and how to use it.
- Cognitive tests - For systems used to complete tasks, including authentication, people may need to do so without cognitive tests.
- Content segments - For systems that present content, people may need content presented in small segments of related content.
- Control distractions - For systems that include notifications or other interruptions to task completion, people may need to control interruptions.
- Control timeout - For systems that time out, people may need to be able to adjust, extend or turn off any time out.
- Default fonts - For systems that present text, people may need text to be written using a font and style that supports readability (example: avoids all caps, italics, and very light weights).
- Distinguish if actionable - For systems that include static and interactive components, people may need interactive components to be clearly distinguishable visually and programmatically from static content.
- Equivalent privacy control - For systems that collect private information, people with disabilities may need the system to maintain my privacy and provide them the same amount of control of their personal information/privacy as other users.
- Error identification - For systems with possible errors, people may need errors to be identified sensorily and programmatically.
- Error prevention - For systems with possible errors, people may need submissions to be checked, confirmable or reversible
- Error suggestion - For systems with detectable errors, people may need error messages to suggest corrections or state that the system is at fault and the user is unable to fix the error.
- Familiar icons - For systems with icons, people may need familiar icons or symbols that help them understand meaning.
- Findable - People may need to easily locate interactive components and important content.
- Language of content - For systems that present language based content, people may need the language of content to be programmatically determinable.
- Multiple Paths - People may need multiple paths through content with unnecessary distractions and interactions.
- Mute all audio - For systems with audio output, people may need the ability to silence or mute all audio output.
- No disruption when activating access feature - People may need to be able to activate their desired modality without a serious disruption such as restarting the computer, closing and restarting an app, or leaving an active task in progress.
- Obvious, avoidable hazards - For systems that include hazards, people may need the hazards to be obvious, easy to avoid, and difficult to trigger.
- Plain language - For systems that present language based content, I need a version that follows plain language principles.
- Privacy protection - For systems that collect private information, people with disabilities may need the system to protect their privacy, even when they are not doing things that other users might be expected to do to guard their own privacy.
- Recognizable signals - For systems that provide alerts, people may need recognizable signals (including feedback and cues) for different alerts or other messages that use signals.
- Recognize human - For systems that use biometrics, people may need human-detection tools that recognize that people who do not look like everyone else are human and are present with equal reliability, for purpose of obstacle avoidance, non-bot verification, etc. This includes tools operated by other people.
- Recognize individual - For systems that use biometric verification tools such as facial appearance, iris pattern, or finger presence, people with atypical biometric factors may need ways to verify their identity with equal reliability to other people.
- Redundant Entry - For systems that require data input, people may need to avoid entering data more than once.
- Safe without reliance on alerts - For systems that present alerts, people may need to use the system safely even if I miss an alert or hazard warning.
- Separate output control - For systems with assistive technology built into the platform or that work with assistive technology, people may need to be able to control output of assistive technology separate from output of content.
- Signposts - People may need clear signposts to indicate specific locations where functionalities can be found.
- Speech with visual highlighting - For systems that provide captions, people may need individual words highlighted synchronously with the text that is being spoken.
- Text alignment - For systems with text, I need text not to be set to full justify.
- Text spacing - For systems that present text, people may need white space between segments of text.
- Timeout warning - For systems that time out, people may need to be notified when a timeout is about to occur and has occurred.
- Timing - People may need no time limit on systems OR for systems that time out, people may need to continue their task without data loss when they log back in after time out occurs.
- Unexpected change of context - For systems with interactive components, people may need to be able to input content without unexpected changes in context.
- Unexpected change of focus - For systems with interactive components, people may need to focus on an element without unexpected changes in context.
- Updating content - For systems with automatically updating content, people may need to be able to control it.
- Use cultural conventions, words, and symbols - For systems that present text and images, people may need content and interfaces that use standard conventions, words, and symbols for the culture, with which they are familiar.
