- 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…
