35 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.).
- Appropriate tactile settings - As someone who uses tactile output, I need to have control over tactile settings so that they better fit my needs (including adjustment of vibration amplitude, and choosing vibration patterns instead of frequency or strength attributes).
- Assistive technology-compatible - For systems with user interfaces, people may need content and operable elements to be accessed and presented through assistive technology.
- Control timeout - For systems that time out, people may need to be able to adjust, extend or turn off any time out.
- Distinguish auditory components - People may need to use assistive technology or accessibility features without interference from other devices.
- 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.
- Distinguish tactile components - For systems with multiple tactile components or channels, people may need to be able to clearly perceive and distinguish the various tactile components.
- Distinguish visual components - For systems with multiple visual components, people may need to be able to clearly perceive and distinguish the various visual components and not have them interfere with each other.
- 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
- Manage individualization features - As a user who uses accessibility features either built into platforms or as part of assitive technologies, I need a way to activate or deactivate individualization features.
- Manage individualization functions - For systems with assistive technology built into the platform, people may need a way to perform, undo, and redo individualization actions.
- Multiple Paths - People may need multiple paths through content with unnecessary distractions and interactions.
- Multiple simultaneous modalities - For systems that present information, people may need the information presented simultaneously in multiple preferred modalities (visual and audio; tactile and audio; visual and tactile; or visual, audio, and tactile).
- Mute all audio - For systems with audio output, people may need the ability to silence or mute all audio output.
- No accessibility feature override - For systems with built-in accessibility features to access systems, people may need applications that do not override or defeat those built-in platform features.
- 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.
- 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.
- Reset accessibility functions - For systems with assistive technology built into the platform or that work with assistive technology, people may need a way to reset accessibility functions to their initial states.
- 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 identification & activation - For system with interactive components, people may need to have separate means of identifying and then activating controls.
- 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.
- Separate selection & activation - For system with interactive components, people may need to have separate means of selecting and then activating controls.
- Signposts - People may need clear signposts to indicate specific locations where functionalities can be found.
- 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.
- Turn off tactile output - For systems with tactile output, people may need to turn off the tactile output from a system.
- 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.
- Visual/tactile feedback at control location - As a user with a disability who might not be paying attention to other output devices, I need to have visual or tactile feedback occur at the same location as the control I am using.
