9 guidance statements support this object characteristic:
- Assistive technology-compatible - For systems with user interfaces, people may need content and operable elements to be accessed and presented through assistive technology.
- Avoid cognitive overloads - For system the presents content and other stimuli, people may need to avoid cognitive overloads?
- 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 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 tactile distractions - For systems with tactile output, people may need to avoid tactile distractions that may prevent them from focusing on a task.
- 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).
- Haptic control - For systems with tactile content, people may need to be able to control haptic output.
- Turn off tactile output - For systems with tactile output, people may need to turn off the tactile output from a system.
