Assistive technology Assistive technology (7-1-1) In Canada and the U.S., the 711 telephone number is used for the Telecommunications Relay Service to translate from TDD for the deaf to voice, and vice versa. The relay service allows hearing-impaired people to converse with the hearing over the phone through an operator. 711 is one of eight N11 codes for abbreviated dialing in the North American Numbering Plan. In the U.S., every phone company is required to connect persons who dial 711 to a TRS call center from a working number, though this may not yet apply to VOIP telephony. ...more on Wikipedia about "7-1-1"

Assistive Technology (AT) is a generic term that includes assistive, adaptive, and rehabilitative devices and the process used in selecting, locating, and using them. AT promotes greater independence for people with disabilities by enabling them to perform tasks that they were formerly unable to accomplish, or had great difficulty accomplishing, by providing enhancements to or changed methods of interacting with the technology needed to accomplish such tasks. According to disability advocates, technology, all too often, is created without regard to people with disabilities, and unnecessary barriers make new technology inaccessible to hundreds of millions. ...more on Wikipedia about "Assistive technology"
Assistive Technology Service Provider Interface (AT-SPI) is a toolkit-neutral way of providing accessibility facilities in applications, developed by the GNOME project. Toolkits provide a logical representation of the content of the application, and helpful assistants like screen readers or magnifiers can then allow disabled persons browse and interact with the applications. ...more on Wikipedia about "Assistive Technology Service Provider Interface"
Audio description refers to an additional narration track for blind and visually impaired viewers of visual media, including television and movies, dance, opera, and visual art. For simplicity, this article focuses on the most common venues for description: TV and film. The description narrator talks through the presentation, describing what is happening on the screen during the natural pauses in the audio (and sometimes during dialogue if deemed necessary). ...more on Wikipedia about "Audio description"
The braille system, named after Louis Braille, is a method that is widely used by blind people to read and write. Each braille character or "cell" is made up of six dot positions, arranged in a rectangle containing two columns of three dots each. A dot may be raised at any of the six positions to form sixty-four combinations, counting the space, in which no dots are raised. For reference purposes, a particular combination may be described by naming the positions where dots are raised, the positions being universally numbered 1 through 3 from top to bottom on the left, and 4 through 6 from top to bottom on the right. For example, dots 1-3-4 would describe a cell with three dots raised, at the top and bottom in the left column and on top of the right column. ...more on Wikipedia about "Braille"
A captioned telephone is a telephone that displays real-time captions of the current conversation. The captions are typically displayed on a screen embedded into the telephone base. A captioned telephone may also be called a CapTel, which is the main brand name for a captioned telephone. ...more on Wikipedia about "Captioned telephone"
Closed captioning (CC) allows deaf and hard of hearing / hearing-impaired people, people learning English as an additional language, people first learning how to read, people in a noisy environment, and others to read a transcript or dialogue of the audio portion of a video, film, or other presentation. As the video plays, text captions are displayed that transcribe, although not always verbatim, what is said and by whom and indicate other relevant sounds. ...more on Wikipedia about "Closed captioning"
Dasher is a computer accessibility tool enabling users to enter text efficiently using a pointing device rather than a keyboard. It has been likened to an arcade game, since to use it you zoom through characters that fly across the screen. It uses a probabilistic predictive model to give priority to more likely character combinations. Dasher can be described as a back-to-front version of arithmetic coding, a data-compression algorithm. Dasher works in all the languages of the world. ...more on Wikipedia about "Dasher"
The Descriptive Video Service (DVS), created by WGBH-TV in Boston, is used by the Public Broadcasting Service (PBS) in the U.S. to provide video description for the visually impaired, so they can better understand what is happening on the video portion of the program. This greatly improves the experience and makes it much more valuable to blind and visually impaired viewers. ...more on Wikipedia about "Descriptive Video Service"

Morse code is a method for transmitting information, using standardized sequences of short and long marks or pulses — commonly known as "dots" and "dashes" — for the letters, numerals and special characters of a message. Originally created for Samuel Morse's electric telegraph in the mid-1830s, it was also extensively used for early radio communication beginning in the 1890s. However, with the development of more advanced communications technologies, the use of Morse code is now largely obsolete, although it is still employed for a few specialized purposes, including navigational radio beacons, and by CW (continuous wave) amateur radio operators. Morse code is the only digital modulation mode designed to be easily read by humans without a computer, making it appropriate for sending automated digital data in voice channels. ...more on Wikipedia about "Morse code"

Paratransit is an alternative mode of passenger transportation that does not follow fixed routes or schedules, like a bus line. Typically vans or mini-buses are used to provide paratransit service. Paratransit services vary on the degree of flexibility they provide their customers. The most flexible paratransit systems offer door-to-door service from any origin to any destination in a service area. Paratransit services are operated by public transit agencies, not-for-profit corporations, and for-profit private companies or operators. ...more on Wikipedia about "Paratransit"
