Wherever possible, consider the requirements of the following groups of users when you write documentation:
- Users with cognitive impairments
- Blind users and users with other vision impairments
- Deaf users and users with other hearing impairment
- Paralyzed users and users with impaired motor skills
Assistive technologies exist to help computer users with various disabilities. An example of assistive technology is the screenreader, which blind people use to view a GUI and read online text. A screenreader normally translates text into synthesized speech or a refreshable Braille display.
