Assistive technology in the context of Eye tracking

Accessibility is the design of products, devices, services, vehicles, or environments to be usable by disabled people. The concept of accessible design and practice of accessible developments ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers).

Accessibility can be viewed as the "ability to access" and benefit from some system or entity. The concept focuses on enabling access for people with disabilities, or enabling access through the use of assistive technology; however, research and development in accessibility brings benefits to everyone. Therefore, an accessible society should eliminate digital divide or knowledge divide.

A screen reader is a form of assistive technology (AT) that renders text and image content as speech or braille output. Screen readers are essential to blind people, and are also useful to people who are visually impaired, illiterate or learning-disabled. Screen readers are software applications that attempt to convey what people with normal eyesight see on a display to their users via non-visual means, like text-to-speech, sound icons, or a braille device. They do this by applying a wide variety of techniques that include, for example, interacting with dedicated accessibility APIs, using various operating system features (like inter-process communication and querying user interface properties), and employing hooking techniques.

Microsoft Windows operating systems have included the Microsoft Narrator screen reader since Windows 2000, though separate products such as Freedom Scientific's commercially available JAWS screen reader and ZoomText screen magnifier and the free and open source screen reader NVDA by NV Access are more popular for that operating system. Apple Inc.'s macOS, iOS, and tvOS include VoiceOver as a built-in screen reader, while Google's Android provides the Talkback screen reader and its ChromeOS can use ChromeVox. Similarly, Android-based devices from Amazon provide the VoiceView screen reader. There are also free and open source screen readers for Linux and Unix-like systems, such as Speakup and Orca.

Universal access to education is the ability of all people to have equal opportunity in education, regardless of their social class, race, gender, sexuality, ethnic background or physical and mental disabilities. The term is used both in college admission for the middle and lower classes, and in assistive technology for the disabled. Some critics feel that this practice in higher education, as opposed to a strict meritocracy, causes lower academic standards. In order to facilitate the access of education to all, countries have right to education.

Universal access to education encourages a variety of pedagogical approaches to accomplish the dissemination of knowledge across the diversity of social, cultural, economic, national and biological backgrounds. Initially developed with the theme of equal opportunity access and inclusion of students with learning or physical and mental disabilities, the themes governing universal access to education have now expanded across all forms of ability and diversity. However, as the definition of diversity is within itself a broad amalgamation, teachers exercising universal access will continually face challenges and incorporate adjustments in their lesson plan to foster themes of equal opportunity of education.

Gerontechnology, also called gerotechnology is an inter- and multidisciplinary academic as well as a professional field that combines various disciplines of gerontology and technology. Sustainability of an aging society depends on our effectiveness in creating technological environments, including assistive technology and inclusive design, for innovative and independent living and social participation of older adults in any state of health, comfort as well as safety. In short, gerontechnology concerns matching technological environments to health, housing, mobility, communication, leisure, work and also the personality/individual dispositions of older people. Gerontechnology is most frequently identified as a subset of HealthTech and is—since the 2010s—more commonly referred to as AgeTech or Agetech in Europe and the United States. Research outcomes form the basis for designers, builders, engineers, manufacturers, and those in the health professions (nursing, medicine, gerontology, geriatrics, environmental psychology, developmental psychology, etc.), to provide an optimum living environment for the widest range of ages.

Switch access is the use of one or more switches to operate computers and other devices and is primarily used by people with severe physical or cognitive impairment. A switch is an assistive technology device that replaces the need to use a computer keyboard or a mouse. It may allow users to control a computer, power wheelchair, video game console, tablet, smartphone, toy, and a variety of other electronic devices.

Windows 2000 is a major release of the Windows NT operating system developed by Microsoft, targeting the server and business markets. It is the direct successor to Windows NT 4.0, and was released to manufacturing on December 15, 1999, and then to retail on February 17, 2000 for all versions, with Windows 2000 Datacenter Server being released to retail on September 26, 2000.

Windows 2000 introduces NTFS 3.0, Encrypting File System, and basic and dynamic disk storage. Support for people with disabilities is improved over Windows NT 4.0 with a number of new assistive technologies, and Microsoft increased support for different languages and locale information. The Windows 2000 Server family has additional features, most notably the introduction of Active Directory, which in the years following became a widely used directory service in business environments. Although not present in the final release, support for Alpha (which was a 64-bit platform but only distributed as a 32-bit OS) was present in its alpha, beta, and release candidate versions. Its successor, Windows XP, only supports x86, x64 and Itanium processors. Windows 2000 was also the first NT release to drop the "NT" name from its product line.
