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 people who are blind, and are useful to people who are visually impaired, illiterate, or have a learning disability. 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, and employing hooking techniques.

Visual impairment, also known as vision impairment, is a medical definition primarily measured based on an individual's better eye visual acuity; in the absence of treatment such as correctable eyewear, assistive devices, and medical treatment– visual impairment may cause the individual difficulties with normal daily tasks including reading and walking. Low vision is a functional definition of visual impairment that is chronic, uncorrectable with treatment or correctable lenses, and impacts daily living. As such low vision can be used as a disability metric and varies based on an individual's experience, environmental demands, accommodations, and access to services. The American Academy of Ophthalmology defines visual impairment as the best-corrected visual acuity of less than 20/40 in the better eye, and the World Health Organization defines it as a presenting acuity of less than 6/12 in the better eye. The term blindness is used for complete or nearly complete vision loss. In addition to the various permanent conditions, fleeting temporary vision impairment, amaurosis fugax, may occur, and may indicate serious medical problems. The abbreviation VIP is sometimes used for Visually Impaired Person, Persons or People.
Digital accessible information system (DAISY) is a technical standard for digital audiobooks, periodicals, and computerized text. DAISY is designed to be a complete audio substitute for print material and is specifically designed for use by people with "print disabilities", including blindness, impaired vision, and dyslexia. Based on the MP3 and XML formats, the DAISY format has advanced features in addition to those of a traditional audio book. Users can search, place bookmarks, precisely navigate line by line, and regulate the speaking speed without distortion. DAISY also provides aurally accessible tables, references, and additional information. As a result, DAISY allows visually impaired listeners to navigate something as complex as an encyclopedia or textbook, otherwise impossible using conventional audio recordings.
Since the Global Positioning System (GPS) was introduced in the late 1980s there have been many attempts to integrate it into a navigation-assistance system for blind and visually impaired people.

Braille technology is assistive technology which allows blind or visually impaired people to read, write, or manipulate braille electronically. This technology allows users to do common tasks such as writing, browsing the Internet, typing in Braille and printing in text, engaging in chat, downloading files and music, using electronic mail, burning music, and reading documents. It also allows blind or visually impaired students to complete all assignments in school as the rest of their sighted classmates and allows them to take courses online. It enables professionals to do their jobs and teachers to lecture using hardware and software applications. The advances in Braille technology are meaningful because blind people can access more texts, books, and libraries, and it also facilitates the printing of Braille texts.
Telesensory Systems, Inc. (TSI) was an American corporation that invented, designed, manufactured, and distributed technological aids for blind and low vision persons. TSI's products helped visually impaired people work independently with computers and with ordinary printed materials.

Accessibility apps are mobile apps that increase the accessibility of a device for individuals with disabilities. Accessibility apps are applications that increase the accessibility of a device or technology for individuals with disabilities. Applications, also known as, application software, are programs that are designed for end users to be able to perform specific tasks. There are many different types of apps, some examples include, word processors, web browsers, media players, console games, photo editors, accounting applications and flight simulators. Accessibility in general refers to making the design of products and environment more accommodating to those with disabilities. Accessibility apps can also include making a current version of software or hardware more accessible by adding features. Accessibility apps main aim is to remove any barriers to technological goods and services, making the app available to any group of society to use. A basic example is that a person who experiences vision impairments is able to access technology through enabling voice recognition and text-to-speech software. Accessibility apps are closely related to assistive technology.
