A full accessibility audit requires the use of both automated evaluation tools and manual user testing with assistive technology.
The following areas should be considered while performing manual testing by a real user with disabilities:
- Keyboard-only user: The user has a motor disability that prevents him or her from operating a computer or devices with anything other than a keyboard. An adaptable keyboard can be used to make operations easier.
- Voice activation user: The user has a motor impairment that requires him or her to use only voice commands to operate a computer or device, which is made possible by assistive technology such as a microphone and dictation software.
- Screen reader user: The user has a visual impairment that requires him or her to use assistive technology such as a screen reader to operate a computer or device through keyboard control and feedback via synthesized audible descriptions of visual elements.
- Users who have color blindness: The user has a visual impairment that restricts access to content in a specific color spectrum. To modify the color spectrum of the content, the user uses system/browser controls or assistive technology.
- Low vision user: The user has a vision impairment that prevents him or her from viewing content at 100% magnification. To increase screen magnification, the user employs system/browser controls or assistive technology.
- Deafness, hearing loss, and being hard of hearing: The user has a hearing impairment that restricts his or her ability to access audio data.
- Cognition and learning disabilities: The user has a learning disability that prevents him or her from accessing content that requires a high level of literacy. Cognitive accessibility covers accessibility considerations for people with cognition and learning disabilities.
