Algebra Earcon (Mathematical Earcon, Math Sound)
A non-speech auditory cue designed to represent the structural components of mathematical expressions, allowing blind users to perceive the overall shape and nesting of an expression without relying s…
Aural Rendering (Auralization, Audio Rendering)
The process of converting visual or textual information into a spoken or auditory representation. In programming accessibility, aural rendering transforms source code into speech output that conveys n…
Braille Mathematics (Math Braille, Braille Math Notation)
The various systems of Braille codes designed specifically to represent mathematical expressions, formulas, and notation in a tactile format readable by blind individuals. Because standard literary Br…
Chemical Markup Language (CML)
An XML-based markup language for representing chemical information including molecular structures, reactions, spectra, and other chemical data in a machine-readable format. CML encodes atoms, bonds, a…
Code Accessibility (Programming Accessibility, Accessible Coding)
The practice of making programming environments, source code, and software development tools usable by people with disabilities, particularly those with visual impairments. Code accessibility encompas…
Content Dictionary (CD, OpenMath Content Dictionary)
A formal specification in the OpenMath standard that provides the definition, description, and properties of a collection of related mathematical symbols. Each Content Dictionary defines symbols used …
Graph (Node-Edge Diagram, Network Diagram)
A data structure and visual representation consisting of nodes (vertices) connected by edges (links) that represent relationships between entities. In computer science and mathematics, graphs are used…
Graph Literacy (Graphical Literacy, Graphicacy)
The ability to read, interpret, and construct graphs and other visual data representations. Graph literacy is a critical component of STEM education and is often tested as part of mathematics and scie…
Haptic User Interface (Haptic UI, Haptic Interface)
A user interface that communicates information through the sense of touch, enabling users to interact with virtual or digital objects by feeling their physical properties such as shape, texture, weigh…
Height-Field Surface (Surface plot, Heightfield plot, 2.5D surface)
A type of 3D data visualisation in which a scalar value (for example, elevation, intensity, pressure, or probability) is plotted over a two-dimensional domain, producing a continuous surface that can …
Line Graph (Line Chart, Line Plot)
A type of data visualization that displays information as a series of data points connected by straight line segments, commonly used to show trends over time or relationships between variables. Line g…
Linear Notation (Linear Mathematical Notation)
A system for representing mathematical expressions in a single line of text, as opposed to the conventional two-dimensional spatial layout used in print mathematics. In standard mathematical notation,…
Marburg Notation (Marburg Mathematical Notation, Marburg Braille)
A Braille-based mathematical notation system developed at the Deutsche Blindenstudienanstalt (German Institute for the Blind) in Marburg, Germany, and widely used in German-speaking countries for read…
Mathematical Braille (Braille Mathematics, Math Braille)
Specialised braille notation systems used to represent mathematical symbols, expressions, and equations. Because standard literary braille has only 64 possible characters (from 6-dot cells), mathemati…
Mathematical Notation Accessibility (Math Accessibility, Accessible Mathematics)
The practice of making mathematical expressions, equations, and formulae perceivable and understandable by people with disabilities, particularly those who are blind or have low vision. Mathematical n…
OpenMath
An XML-based standard for representing mathematical objects and their semantics in a machine-readable format. Unlike MathML, which has both presentation (visual layout) and content (semantic structure…
Syntactic Structure (Program Structure, Code Structure)
The hierarchical arrangement of elements in a programming language according to the language's grammar rules, including how statements, expressions, and blocks are nested and related to one another. I…
