25 guidance statements support this support needed:
- Avoid auditory distractions - For systems with auditory output, people may need to avoid auditory distractions that may prevent them from focusing on a task.
- Avoid cognitive overloads - For system the presents content and other stimuli, people may need to avoid cognitive overloads?
- Avoid contrast changes - For systems that present content, people may need to avoid changes to the foreground color that reduce the contrast with the background color.
- 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 excessive vibration - For systems that provide tactile content, people may need to limit the amount of vibration so that it does not interfere with their ability to perceive information.
- Avoid glare - For stationary or installed systems, people may need to avoid reflective and environmental glare.
- Avoid interruptions - For systems that include notifications, advertisements, browser pop-ups, or other interruptions to task completion, people may need to avoid the unnecessary interruptions.
- Avoid olfactory distractions - For systems with olfactory output, people may need to avoid olfactory distractions that may prevent them from focusing on a task.
- Avoid overwhelming audio - For systems with audio content, people may need to avoid audio events that may overload their perception.
- 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.
- Avoid overwhelming visuals - For systems with visual content, people may need to avoid visual events that may overload their perception.
- Avoid tactile distractions - For systems with tactile output, people may need to avoid tactile distractions that may prevent them from focusing on a task.
- Avoid visual distractions - For systems with visual output, people may need to avoid visual distractions that may prevent them from focusing on a task.
- Harmful triggering content - For systems with potentially triggering content, people may need to identify sensitive content in advance and avoid it.
- Harmful visual content - For systems that provide visual content, people may need to identify flashing, motion, and other visual effects that can harm them and avoid it.
- Motion errors - For systems that use motion based input, people may need to turn it off.
- 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).
- No audio seizure triggers - For systems with audio output, people may need to to avoid auditory patterns that cause seizures.
- 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 electromagnetic harm - People may need to have systems that do not give off inappropriate electromagnetic radiation.
- No visual seizure triggers - For systems with visual content, people may need to be able to avoid visual patterns that cause seizures or adjust the viewing of such visual patterns so that they are safe.
- Obvious, avoidable hazards - For systems that include hazards, people may need the hazards to be obvious, easy to avoid, and difficult to trigger.
- 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.
