BLE Beacon(also: Bluetooth Low Energy Beacon, iBeacon, Bluetooth Beacon)

A BLE (Bluetooth Low Energy) beacon is a small wireless transmitter that broadcasts a signal at regular intervals, which can be detected by nearby smartphones to determine a user's indoor location. In accessibility contexts, networks of BLE beacons are widely used to enable…

Bluetooth(also: BLE, Bluetooth Low Energy)

A short-range wireless communication standard used to exchange data between devices over distances of up to approximately 30 metres. In accessibility, Bluetooth is widely used in assistive technology: hearing aids use Bluetooth to stream audio directly from phones and…

Bone Conduction Headphones(also: Bone Conducting Headphones, Bonephones)

Audio devices that transmit sound through the bones of the skull directly to the inner ear, bypassing the outer and middle ear. Unlike traditional headphones, bone conduction headphones leave the ear canal open, allowing users to hear environmental sounds while receiving audio…

Bone conduction(also: Bone conduction hearing, Bone anchored hearing)

Bone conduction is a method of sound transmission that delivers audio vibrations through the bones of the skull directly to the inner ear, bypassing the outer and middle ear. Bone conduction technology is used in hearing aids and headphones designed for people with conductive…

Bone conduction headphones(also: Bone conduction earphones, Bone conduction audio)

Audio devices that transmit sound through vibrations on the skull bones rather than through the ear canal, leaving the ears open to ambient environmental sounds. For people with visual impairments using navigation assistants, bone conduction headphones are essential for…

Braille Embosser(also: Braille Printer)

A specialized printer that produces braille text and tactile graphics by pressing raised dots into heavy paper or card stock. Braille embossers range from personal devices to high-volume production machines and vary in their ability to produce graphics versus text-only output.…

Braille Notetaker(also: Braille Note Taker, Braille PDA)

A portable electronic device designed specifically for blind and low-vision users that combines a refreshable Braille display with a Braille keyboard for input, allowing users to take notes, read documents, browse the web, and manage files. Unlike general-purpose computers with…

Braille display(also: Refreshable braille display, Braille terminal)

An electromechanical device that renders text as tactile braille characters using small pins that raise and lower dynamically. Braille displays connect to computers and mobile devices, enabling blind and deafblind users to read digital content through touch. They are…

Breadboard(also: Solderless Breadboard, Protoboard)

A reusable plastic board with a grid of interconnected holes used for building temporary electronic circuits without soldering. Components are inserted into the holes and connected by internal metal strips. Breadboards are essential tools in electronics education and…

Buddy Button

A widely used commercial assistive technology switch manufactured by AbleNet, designed for single-switch access to computers, communication devices, and adapted toys. Buddy Buttons are large, colorful, easy-to-activate mechanical switches that can be positioned on various body…
