18 guidance statements support this object characteristic:
- Alternatives to motion-based input - For systems that use motion or multi-dimensional movement for input, people may need alternatives to motion-based input.
- Assistive technology-compatible - For systems with user interfaces, people may need content and operable elements to be accessed and presented through assistive technology.
- Concurrent input - For systems that take input, people may need to use concurrent input mechanisms.
- Cool down - For systems that take input, people may need a .05 second period between inputs.
- 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.
- Modified motion-based input - For systems that uses motion based input tools, people may need reduced or slowed motion and rest breaks.
- 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 navigation traps - For systems with interactive components, people may need to move to and away from any interactive element using any user agent or input modality.
- Precise timing - For systems that support task completion or game play, people may need actions that do not require precise timing, can be carried out while paused, or skipped.
- Repetitive strain injuries - For systems that require that involve extensive repetitive actions for input, people may need alternate input devices or approaches.
- 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 complex input controls, people may need simple alternatives.
- Simple controls - For systems with input controls, people may need those controls to be simple.
- Single action - For systems that use fine motor control based input, some users may need an alternative input mechanism that requires only a single action and a single pointer to input information and navigate (alternative to multi-point gestures, dragging, pointer movements, etc)
- Software control - For systems that require physical operation, people may need to access functionality through software that is ordinarily controlled through hardware.
