Assistive technology (AT) is a term for assistive, adaptive, and rehabilitative devices for people with disabilities and the elderly. Disabled people often have difficulty performing activities of daily living (ADLs) independently, or even with assistance. ADLs are self-care activities that include toileting, mobility (ambulation), eating, bathing, dressing, grooming, and personal device care. Assistive technology can ameliorate the effects of disabilities that limit the ability to perform ADLs. Assistive technology promotes greater independence by enabling people to perform tasks they were formerly unable to accomplish, or had great difficulty accomplishing, by providing enhancements to, or changing methods of interacting with, the technology needed to accomplish such tasks. For example, wheelchairs provide independent mobility for those who cannot walk, while assistive eating devices can enable people who cannot feed themselves to do so. Due to assistive technology, disabled people have an opportunity of a more positive and easygoing lifestyle, with an increase in "social participation", "security and control", and a greater chance to "reduce institutional costs without significantly increasing household expenses." In schools, assistive technology can be critical in allowing students with disabilities to access the general education curriculum. Students who experience challenges writing or keyboarding, for example, can use voice recognition software instead. Assistive technologies assist people who are recovering from strokes and people who have sustained injuries that affect their daily tasks.
Braille is a tactile writing system used by people who are visually impaired. It can be read either on embossed paper or by using refreshable braille displays that connect to computers and smartphone devices. Braille can be written using a slate and stylus, a braille writer, an electronic braille notetaker or with the use of a computer connected to a braille embosser.
A braille embosser is an impact printer that renders text as tactile braille cells. Using braille translation software, a document or digital text can be embossed with relative ease. This makes braille production efficient and cost-effective. Braille translation software may be free and open-sourced or paid.
Louis Braille was a French educator and the inventor of a reading and writing system named after him, braille, intended for use by visually impaired people. His system is used worldwide and remains virtually unchanged to this day.

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.
Braille music is a braille code that allows music to be notated using braille cells so music can be read by visually impaired musicians. The system was incepted by Louis Braille.

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.
The Associated Services for the Blind & Visually Impaired (ASB) is a private non-profit organization in Philadelphia, Pennsylvania. It assists those living with vision loss to achieve independence through education, support services to advance necessary skills, and community connections. ASB collaborates with local, regional and national partners to provide additional resources and opportunities to clients.
A sighted child who is reading at a basic level should be able to understand common words and answer simple questions about the information presented. They should also have enough fluency to get through the material in a timely manner. Over the course of a child's education, these foundations are built on to teach higher levels of math, science, and comprehension skills. Children who are blind not only have the education disadvantage of not being able to see: they also miss out on the very fundamental parts of early and advanced education if not provided with the necessary tools.
The Braille Challenge is an annual two-stage Braille literacy competition designed to motivate blind students to emphasize their study of Braille. The program parallels with the importance and educational purpose of a spelling bee for sighted children. Braille is a reading and writing method that breaks language into a code of raised dots. There are three grades of braille:
The Mountbatten Brailler is an electronic machine used to type braille on braille paper. It uses the traditional "braille typewriter keyboard" of the Perkins Brailler with modern technology, giving it a number of additional features such as word processing, audio feedback and embossing. The machine was pioneered and developed at the United Kingdom's Royal National College for the Blind in Hereford by Ernest Bate.

Braigo is a Braille printer design. Braigo version 1.0 uses a Lego Mindstorms EV3 kit, which includes a microprocessor with assorted components such as electric motors, sensors and actuators. Braigo v1.0 was designed by 13-year-old Shubham Banerjee in January 2014, as an entry in 7th grade school science fair project. The model was based on the PLOTT3R, a bonus model released with the EV3 kit and originally designed by Ralph Hempel. The cost was said to be about US$350 or 250 Euros for the Lego Mindstorms EV3 kit and some extra commonly used hardware whereas a conventional Braille printer retails starting from about $1,900.
