40 guidance statements support this support needed:
- 2D alternative to 3D - For systems that provide three dimensional content, people may need three dimensional visual information presented using only two dimensions.
- Alternate versions - For systems that present language based content, may need alternative versions of the content (iconography, simplified, summarized, etc.)
- Alternative to auditory alerts - For systems that provide auditory alerts regarding critically important information, people may need to receive visual or tactile alerts instead.
- Alternative to holding - For systems that use buttons to input data, people may need an alternative input to holding a button down.
- Alternative to tactile alerts - For systems that provide visual alerts regarding critically important information, people may need to receive auditory or visual alerts instead.
- Alternative to visual alerts - For systems that provide visual alerts regarding critically important information, people may need to receive auditory or tactile alerts instead.
- Alternatives to motion-based input - For systems that use motion or multi-dimensional movement for input, people may need alternatives to motion-based input.
- Auditory equivalents - For systems with auditory content, people may need that content presented programmatically or need equivalent visual and tactile versions.
- Changing content alternatives - For systems that provide changes in content (including state, role or value), people may need visual, auditory, and tactile indications of the change.
- Control sensitivity - For systems that require physical operation, people may need to be able to adjust the sensitivity of controls.
- Error identification - For systems with possible errors, people may need errors to be identified sensorily and programmatically.
- Human help - For systems that may require assistance, people may need easy access to trained human help.
- Limited vision distinguish distractions - For systems that present content that is not related to a task or from a different source than the main content, people may need the secondary content to be clearly indicated programmatically, visually with high luminosity, or with equivalent auditory and tactile versions.
- Meaningful sequence - For systems that present content, people may need the content to be available in a meaningful sequence both sensorily and programmatically.
- Monoaural information - For systems that present multi-channel audio information, including directional information, people may need the same information available in a monoaural form.
- 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).
- Name, role, value, state - Overlap with programmatic structure and relationships.
- 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.
- No-color equivalents - For systems that use color to indicate meaning, people may need information provided through chromaticity to be available in another visual manner.
- Non-visual instructions - For systems that prsent visually oriented instructions, people may need non-visual cues as well.
- Nonauditory instruction references - For systems that provide instructions, people may need instructions that reference auditory information to include an additional programmatic reference or provide equivalent visual or tactile references.
- Nongustatory nonolfactory alternate instruction references - For systems that provide instructions, people may need instructions that reference smell or taste to include an additional programmatic reference or provide equivalent visual, auditory, and tactile references
- 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
- Nonvisual instruction references - For systems that provide instructions, people may need instructions that reference visual information to include an additional programmatic reference or provide equivalent auditory or tactile references.
- Noticeable non-auditory alert - For systems that present auditory, time-sensitive alerts, people may need the alerts to be in a format that they will notice immediately, such as flashing lights or insistent vibration.
- Noticeable non-visual alert - For systems that present visual, time-sensitive alerts, people may need the alerts to be in a format that they will notice immediately, such an auditory alert or insistent vibration.
- Notifications in auditory alternatives - For systems that present auditory notifications, people may need visual or tactile equivalents.
- Number alternatives - For systems that present numbers or numeric content, people may need alternative ways to understand what the numbers mean.
- Olfactory equivalents - For systems with olfactory or gustatory content, people may need that content presented programmatically or need equivalent visual, auditory, and tactile versions.
- Output modality choice - As a user with limited or no vision or with limited or no hearing, I need to be able to choose modalities to be used for outputs from the system.
- Plain language - For systems that present language based content, I need a version that follows plain language principles.
- Programmatic structure and relationships - For systems that present content, people may need structure and relationships (title, labels, section headings) presented sensorily and programmatically.
- 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 login - For systems with a login, people may need a simple way to log in.
- 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)
- Supplement auditory location cues - For systems that present auditory cues to location in space, people may need the location represented in other forms, such as visual, textual, or haptic cues.
- Visual equivalents - For systems with media content, people may need audio descriptions or a text transcript available.
