WAssistive technology (AT) is a term for assistive, adaptive, and rehabilitative devices for people with disabilities or the elderly population. People with disabilities 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, people with disability 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."
WAn assistive cane is a walking stick used as a crutch or mobility aid. A cane can help redistribute weight from a lower leg that is weak or painful, improve stability by increasing the base of support, and provide tactile information about the ground to improve balance. In the US, ten percent of adults older than 65 years use a cane, and 4.6 percent use walkers.
WAssistive eating devices include devices ranging from low-tech utensils to high-tech powered robotic eating equipment. Low tech eating devices include utensils, plates and bowls with lips that make scooping food easier. Cups and mugs, and even a standard disposable straw can be considered assistive drinking devices. They are used by people when they have difficulty eating or drinking independently. These devices are typically used for people with disabilities, but can also be used for children or people that have poor dexterity. They can promote independence during meal times, but in many cases also can reduce the caregiver workload during meals. "Assistive eating devices can increase self-care, increase self-esteem associated with increased independence, increase safety during meals, and make meal-time better for caregiver staff…".
WAn assistive listening device (ALD) is part of a system used to improve hearing ability for people in a variety of situations where they are unable to distinguish speech in noisy environments. Often, in a noisy or crowded room it is almost impossible for an individual who is hard of hearing to distinguish one voice among many. This is often exacerbated by the effect of room acoustics on the quality of perceived speech. Hearing aids are able to amplify and process these sounds, and improve the speech to noise ratio. However, if the sound is too distorted by the time it reaches the listener, even the best hearing aids will struggle to unscramble the signal. Assistive listening devices offer a more adaptive alternative to hearing aids, but can be more complex and cumbersome.
WAssistive technology in sport is an area of technology design that is growing. Assistive technology is the array of new devices created to enable sports enthusiasts who have disabilities to play. Assistive technology may be used in disabled sports, where an existing sport is modified to enable players with a disability to participate; or, assistive technology may be used to invent completely new sports with athletes with disabilities exclusively in mind.
WATutor is an Open Source Web-based Learning Content Management System (LCMS).
WAudio induction loop systems, also called audio-frequency induction loops (AFILs) or hearing loops, are an assistive listening technology for individuals with reduced ranges of hearing.
WBone conduction is the conduction of sound to the inner ear primarily through the bones of the skull, allowing the hearer to perceive audio content without blocking the ear canal. Bone conduction transmission occurs constantly as sound waves vibrate bone, specifically the bones in the skull, although it is hard for the average individual to distinguish sound being conveyed through the bone as opposed to the sound being conveyed through the air via the ear canal. Intentional transmission of sound through bone can be used with individuals with normal hearing — as with bone-conduction headphones — or as a treatment option for certain types of hearing impairment. Bone generally conveys lower-frequency sounds better than higher frequency sounds.
WBraille is a tactile writing system used by people who are visually impaired. It is traditionally written with embossed paper. Braille users can read computer screens and other electronic supports using refreshable braille displays. They can write braille with the original slate and stylus or type it on a braille writer, such as a portable braille notetaker or computer that prints with a braille embosser.
WThe Canadian currency tactile feature is a feature on the Canadian Journey and Frontier series of Canadian banknotes to aid people who are visually impaired to identify the notes. The feature indicates the banknote denomination in the upper left corner of the face side of the bill using a series of raised dots. It was suggested by Bruno Thériault, an administrator for the Canadian National Institute for the Blind, and designed by Susan Lederman, a professor of psychology at Queen's University.
WClosed captioning (CC) and subtitling are both processes of displaying text on a television, video screen, or other visual display to provide additional or interpretive information. Both are typically used as a transcription of the audio portion of a program as it occurs, sometimes including descriptions of non-speech elements. Other uses have included providing a textual alternative language translation of a presentation's primary audio language that is usually burned-in to the video and unselectable.
WClosed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point (P2P), point-to-multipoint (P2MP), or mesh wired or wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring.
WA crutch is a mobility aid that transfers weight from the legs to the upper body. It is often used by people who cannot use their legs to support their weight, for reasons ranging from short-term injuries to lifelong disabilities.

WA monocular is a modified refracting telescope used to magnify the images of distant objects by passing light through a series of lenses and usually also prisms. Most modern monoculars use prisms instead of relay lenses to ensure an erect image, resulting in a lightweight, compact telescope. The typical volume and weight of a monocular are less than half of a pair of binoculars having similar optical properties, making a monocular easier to carry and also proportionally less expensive. This is due to the fact that binoculars are essentially two sets of monoculars packed together — one for each eye. Monoculars only produce one 2-dimensional image, while binoculars produce two parallaxed images to allow stereopsis and depth perception.
WThe 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.
WParatransit is the term used in North America, also known by other names such as community transport (UK) for transportation services that supplement fixed-route mass transit by providing individualized rides without fixed routes or timetables. Paratransit services may vary considerably on the degree of flexibility they provide their customers. At their simplest they may consist of a taxi or small bus that will run along a more or less defined route and then stop to pick up or discharge passengers on request. At the other end of the spectrum—fully demand responsive transport—the most flexible paratransit systems offer on-demand call-up door-to-door service from any origin to any destination in a service area. In addition to public transit agencies, paratransit services may be operated by community groups or not-for-profit organizations, and for-profit private companies or operators.
WThe Perkins Brailler is a "braille typewriter" with a key corresponding to each of the six dots of the braille code, a space key, a backspace key, and a line space key. Like a manual typewriter, it has two side knobs to advance paper through the machine and a carriage return lever above the keys. The rollers that hold and advance the paper have grooves designed to avoid crushing the raised dots the brailler creates.
WProportional myoelectric control can be used to activate robotic lower limb exoskeletons. A proportional myoelectric control system utilizes a microcontroller or computer that inputs electromyography (EMG) signals from sensors on the leg muscle(s) and then activates the corresponding joint actuator(s) proportionally to the EMG signal.
WThe Rear Window captioning system (RWC) is a method for presenting, through captions, a transcript of the audio portion of a film in theatres for deaf and hard-of-hearing people. The system was co-developed by WGBH and Rufus Butler Seder.
WIn electronics, a remote control or clicker is an electronic device used to operate another device from a distance, usually wirelessly. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other home appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance. This is primarily a convenience feature for the user. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside.
WThe Royal National College for the Blind (RNC) is a co-educational specialist residential college of further education based in the English city of Hereford.

WA stenomask is a hand-held microphone built into a padded, sound-proof enclosure that fits over the speaker's mouth or nose and mouth. Some lightweight versions may be fitted with an elastic neck strap to hold them in place while freeing the user's hands for other tasks. The purpose of a stenomask is to allow a person to speak without being heard by other people, and to keep background noise away from the microphone.
WSubtitles are text derived from either a transcript or screenplay of the dialogue or commentary in films, television programs, video games, and the like, usually displayed at the bottom of the screen, but can also be at the top of the screen if there is already text at the bottom of the screen. They can either be a form of written translation of a dialogue in a foreign language, or a written rendering of the dialogue in the same language, with or without added information to help viewers who are deaf or hard-of-hearing, who cannot understand the spoken language, or who have accent recognition problems to follow the dialogue.
WSurtitles, also known as supertitles, SurCaps, OpTrans, are translated or transcribed lyrics/dialogue projected above a stage or displayed on a screen, commonly used in opera, theatre or other musical performances. The word "surtitle" comes from the French language "sur", meaning "over" or "on", and the English language word "title", formed in a similar way to the related subtitle. The word Surtitle is a trademark of the Canadian Opera Company.
WTactile is a real-time text-to-braille translation device currently under development at the Massachusetts Institute of Technology. It was conceived by a team of undergraduate students, competing as "Team 100% Enthusiasm", during a 15-hour MIT "hackathon". The device is slid over printed text and a camera captures images of the words and sends them to a microcontroller. The information moves the pins up and down, translating the text into Braille. Once on the market it is hoped to be much cheaper than existing devices.
WTactile paving is a system of textured ground surface indicators found on footpaths, stairs and railway station platforms, to assist pedestrians who are vision impaired.
WA telecommunications device for the deaf (TDD) is a teleprinter, an electronic device for text communication over a telephone line, that is designed for use by persons with hearing or speech difficulties. Other names for the device include teletypewriter (TTY), textphone, and minicom.
WA telecommunications relay service, also known as TRS, relay service, or IP-relay, or Web-based relay service, is an operator service that allows people who are deaf, hard of hearing, deafblind, or have a speech disorder to place calls to standard telephone users via a keyboard or assistive device. Originally, relay services were designed to be connected through a TDD, teletypewriter (TTY) or other assistive telephone device. Services gradually have expanded to include almost any real-time text capable technology such as a personal computer, laptop, mobile phone, PDA, and many other devices. The first TTY was invented by deaf scientist Robert Weitbrecht in 1964. The first relay service was established in 1974 by Converse Communications of Connecticut.
WTelehealth is the distribution of health-related services and information via electronic information and telecommunication technologies. It allows long-distance patient and clinician contact, care, advice, reminders, education, intervention, monitoring, and remote admissions. Telemedicine is sometimes used as a synonym, or is used in a more limited sense to describe remote clinical services, such as diagnosis and monitoring. When rural settings, lack of transport, a lack of mobility, decreased funding, or a lack of staff restrict access to care, telehealth may bridge the gap. as well as provider distance-learning; meetings, supervision, and presentations between practitioners; online information and health data management and healthcare system integration. Telehealth could include two clinicians discussing a case over video conference; a robotic surgery occurring through remote access; physical therapy done via digital monitoring instruments, live feed and application combinations; tests being forwarded between facilities for interpretation by a higher specialist; home monitoring through continuous sending of patient health data; client to practitioner online conference; or even videophone interpretation during a consult.
