ASCII (American Standard Code for Information Interchange)
A character encoding standard that uses numeric codes to represent letters, digits, punctuation, and control characters in computers and communication equipment. ASCII assigns values 0-127 to 128 char…
Augmented Reality (AR, Mixed Reality)
A technology that overlays digital information—such as images, text, or 3D models—onto the user's view of the real world, typically through smartphones, tablets, smart glasses, or projection systems. …
Augmented Reality (AR) (AR, Augmented Reality)
An interactive technology that overlays digital information — such as text, images, or video — onto the real-world environment in real time. In accessibility contexts, AR has significant potential for…
Automatic Speech Recognition (ASR) (ASR, Speech-to-Text, Voice Recognition, Auto-Captioning)
Technology that converts spoken language into written text using computational algorithms and machine learning models. ASR powers auto-captioning features in video conferencing, media players, and ass…
Color Gamut (Colour Gamut, Gamut)
The complete range of colours that can be represented or reproduced by a particular colour space, display device, or visual system. In the context of colour vision, a trichromat's gamut encompasses th…
Color Space (Colour Space, Color Model)
A mathematical model that describes the range of colours that can be represented as numerical values, typically using three or more coordinates. Common colour spaces include RGB (red, green, blue), us…
Constructive Solid Geometry (CSG)
A technique in 3-D modeling that creates complex shapes by combining simpler geometric primitives (cubes, spheres, cylinders) using boolean operations such as union, difference, and intersection. CSG …
Crowdsourcing (Crowd-Sourced Data, Community Reporting)
A method of collecting data, information, or contributions from a large number of people, typically via the internet, rather than relying on a single authoritative source. In accessibility contexts, c…
Digital Audio Workstation (DAW)
Software used for recording, editing, mixing, and producing audio content, such as Reaper, Logic Pro, Cubase, or Pro Tools. DAWs present significant accessibility challenges for blind and visually imp…
Digital Television (DTV, Digital TV, iTV, Interactive Television)

Fuzzy Logic (Fuzzy Inference)
Fuzzy logic is a form of many-valued logic that deals with approximate reasoning, where truth values range continuously between 0 and 1 rather than being strictly true or false. In assistive technolog…
Geocoding (Geo-coding, Geographic Coding)
The process of associating geographic coordinates (latitude and longitude) or location identifiers with objects, markers, or data points. In accessibility contexts, geocoding is used to tag physical l…
Head-Mounted Display (HMD) (HMD, Head-Mounted Display, Smart Glasses, AR Glasses)
A display device worn on the head that places visual content in front of one or both eyes. Head-mounted displays include AR smart glasses (like Vuzix Blade), VR headsets, and mixed reality devices. In…
Huffman Coding (Huffman Algorithm, Huffman Tree)
A data compression algorithm that assigns shorter codes to more frequently occurring symbols and longer codes to less frequent ones, producing an optimal prefix-free encoding. In accessibility and AAC…
