above, rather it extends to anyone who is experiencing any permanent, temporary or situational disability. Situational disability refers to someone who may be experiencing a boundary based on the current experience. For example, a person may be situationally one-handed if they are carrying a baby. Web accessibility should be mindful of users experiencing a wide variety of barriers. According to a 2018 WebAIM global survey of web accessibility practitioners, close to 93% of survey respondents received no formal schooling on web accessibility. Assistive technologies used for web browsing Individuals living with a disability use assistive technologies such as the following to enable and assist web browsing: Screen reader software, which can read out, using synthesized speech, either selected elements of what is being displayed on the monitor (helpful for users with reading or learning difficulties), or which can read out everything that is happening on the computer (used by blind and vision impaired users). Braille terminals, consisting of a refreshable braille display which renders text as braille characters (usually by means of raising pegs through holes in a flat surface) and either a mainstream keyboard or a braille keyboard. Screen magnification software, which enlarges what is displayed on the computer monitor, making it easier to read for vision impaired users. Speech recognition software that can accept spoken commands to the computer, or turn dictation into grammatically correct text – useful for those who have difficulty using a mouse or a keyboard. Keyboard overlays, which can make typing easier or more accurate for those who have motor control difficulties. Access to subtitled or sign language videos for deaf people. Guidelines on accessible web design Web Content Accessibility Guidelines In 1999 the Web Accessibility Initiative, a project by the World Wide Web Consortium (W3C), published the Web Content Accessibility Guidelines WCAG 1.0. On 11 December 2008, the WAI released the WCAG 2.0 as a Recommendation. WCAG 2.0 aims to be up to date and more technology neutral. Though web designers can choose either standard to follow, the WCAG 2.0 have been widely accepted as the definitive guidelines on how to create accessible websites. Governments are steadily adopting the WCAG 2.0 as the accessibility standard for their own websites. In 2012, the Web Content Accessibility Guidelines were also published as an ISO/IEC standard: "ISO/IEC 40500:2012: Information technology – W3C Web Content Accessibility Guidelines (WCAG) 2.0".
