Braille Music (Braille Music Notation, Music Braille)
A tactile system for encoding Western music notation using the same six-dot cells as literary Braille. Braille Music is read through touch rather than sight, making it particularly useful for blind mu…
Braille Music Notation (Braille Music, Braille Music Code)
A tactile system for representing musical notation using the six-dot braille cell, encoding pitch, duration, dynamics, and other musical information for blind and visually impaired musicians. Unlike s…
Braille Notetaker (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 docu…
Braille Screen Input (BSI)
A built-in iOS accessibility feature that turns the touchscreen of an iPhone or iPad into a virtual Braille keyboard. When activated through VoiceOver, users can type Braille characters by tapping the…
Braille Slate and Stylus (Slate and Stylus, Braille Writing Frame)
A low-cost, portable tool for writing Braille by hand, consisting of a hinged metal or plastic template (slate) with rows of cells and a pointed tool (stylus) used to press dots into paper from the re…
Braille Textbook (Braille Book, Braille Edition)
A textbook transcribed into Braille for use by students and teachers who are blind. Braille textbooks are significantly larger and more expensive to produce than print textbooks, often requiring multi…
Braille Translation (Braille Transcription, Text-to-Braille Translation)
The process of converting printed text or digital text content into Braille, either manually by a trained transcriber or automatically using software such as Duxbury. Braille translation involves more…
Braille Translation Software (Braille Transcription Software, Braille Converter)
Software that converts print text into braille or braille into print, applying the appropriate contraction rules, formatting conventions, and code systems (such as UEB or Nemeth). Braille translation …
Braille Translator (Braille translation software)
Software that converts print text (and sometimes marked-up content such as LaTeX or MathML) into correctly formatted Braille output, applying contractions, code switches, and page-layout rules. Braill…
Braille display (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 …
Braille literacy (Braille fluency)
The ability to read and write using the Braille tactile writing system of raised dots. Braille literacy rates among blind people have declined significantly — from over 50% in the 1960s to under 10% i…
BrailleNote (BrailleNote Touch, Braille Notetaker)
A portable electronic device designed for blind users that combines a refreshable braille display with note-taking, reading, and computing capabilities. BrailleNote devices (manufactured by HumanWare)…
Brailler (Braille Writer, Perkins Brailler)
A mechanical or electronic device for writing Braille, functioning similarly to a typewriter with six keys corresponding to the six dots of a Braille cell. Braillers are significantly faster and easie…

Brain-Computer Interface (BCI, Brain-Machine Interface, BMI, Neural Interface)
A technology that enables direct communication between the brain and an external device by detecting and interpreting neural activity, typically through electroencephalography (EEG) or electromyograph…
Brain-Computer Interface (BCI, Brain-Machine Interface, BMI)
A direct communication pathway between the brain and an external device that enables users to control computers, prosthetics, or other systems using neural signals rather than physical movement. BCIs …
Brain-Computer Interface (BCI, Brain-Machine Interface, BMI, Neural Interface)
A technology that enables direct communication between the brain and an external device by detecting and interpreting neural signals. BCIs can use invasive methods (implanted electrodes) or non-invasi…
Brain-Machine Interface (BMI, Brain-Computer Interface, BCI, Neural Interface)
A technology that translates brain activity—typically measured via electroencephalography (EEG), electrocorticography, or implanted electrodes—into commands for controlling external devices such as co…
BrainGate (BrainGate2)
A long-running multi-site clinical trial program (ClinicalTrials.gov NCT00912041) that evaluates implantable intracortical brain-computer interfaces in people with paralysis from spinal cord injury, A…
