9 guidance statements support this accessibility characteristic:
- Assistive technology-compatible - For systems with user interfaces, people may need content and operable elements to be accessed and presented through assistive technology.
- 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.
- Interface access - For systems used to play games, people may need to access all areas of the interface with the same input method as the gameplay.
- 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.
- Separate identification & activation - For system with interactive components, people may need to have separate means of identifying and then activating controls.
- Separate selection & activation - For system with interactive components, people may need to have separate means of selecting and then activating controls.
- Simple controls - For systems with input controls, people may need those controls to be simple.
- Simple controls - For systems with complex input controls, people may need simple alternatives.
