Assistive technology

Assistive technology is a generic term for devices and modifications (for a person or within a society) that help overcome or remove a disability. The first recorded example of the use of a prosthesis dates to at least 1800 BC. The wheelchair dates from the 17th century. The curb cut is a related structural innovation. Other examples are standing frames, text telephones, accessible keyboards, large print, braille, and speech recognition software. Disabled people often develop adaptations which can be personal (e.g. strategies to suppress tics in public) or community (e.g. sign language in d/Deaf communities).

As the personal computer has become more ubiquitous, various organizations have formed to develop software and hardware to make computers more accessible for disabled people. Some software and hardware, such as Voice Finger, Freedom Scientific 's JAWS, the Free and Open Source alternative Orca etc. have been specifically designed for disabled people while other software and hardware, such as Nuance 's Dragon NaturallySpeaking, were not developed specifically for disabled people, but can be used to increase accessibility. The LOMAK keyboard was designed in New Zealand specifically for persons with disabilities. The World Wide Web consortium recognized a need for International Standards for Web Accessibility for persons with disabilities and created the Web Accessibility Initiative (WAI). As at Dec 2012 the standard is WCAG 2.0 (WCAG = Web Content Accessibility Guidelines).
