30 guidance statements support this individual ability:
- Alternative to tactile alerts - For systems that provide visual alerts regarding critically important information, people may need to receive auditory or visual alerts instead.
- 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.
- Avoid excessive heat - For systems that require physical operation, people may need to limit the amount of heat (or other radiation) on controls so that it does not cause discomfort or injury.
- Avoid excessive heat - For systems that provide tactile content, people may need to limit the amount of heat (or other radiation) felt at touch points so that it does not interfere with their ability to perceive tactile information
- Avoid overwhelming haptics - For systems with tactile content, people may need to avoid haptic effects events that may overload their perception or prevent them from completing a tactile task.
- 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.
- Haptic control - For systems with tactile content, people may need to be able to control haptic output.
- Input modality choice - For systems that accept input, people may need to be able to choose modalities to be used for inputs to the system.
- Manage individualization features - For systems with assistive technology built into the platform, people may 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.
- No chemical harm - People may need to systems made of safe material, that do not give off chemicals to which they are sensitive or have an allergy.
- 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.
- No electromagnetic harm - People may need to have systems that do not give off inappropriate electromagnetic radiation.
- No reliance on specific sense to avoid injury - For system the presents content and other stimuli, people may need alternative versions of content that do not rely on a specific sense to avoid injury.
- Nontactile alternate instruction references - For systems that provide instructions, people may need instructions that reference touch to include an additional programmatic reference or provide equivalent visual or auditory references
- 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.
- 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.
- Status indicators - For systems with toggle controls that have states, people may need the state of the system available to them.
- 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.
- User feedback - People may need an accessible way to provide user feedback.
- 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.
- Without fear of consequences - People may need to be able to use products without the fear of negative consequences if they make mistakes.
