- 3D Printed Tactile Model (3D tactile model, Tactile 3D model, 3D-printed accessibility model)
- A physical, three-dimensional object produced by additive manufacturing (for example fused deposition modelling or stereolithography) that is designed to be explored by touch rather than sight. 3D pri…
- Active Exploration (User-Directed Exploration)
- An interaction paradigm in non-visual interfaces where users physically control their navigation through information, discovering content by directing a pointer, stylus, or finger across a surface or …
- 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…
- Flowchart
- A type of node-link diagram used to represent a process, workflow, or algorithm as a sequence of steps connected by directional arrows. Flowcharts use conventional shape vocabularies (rectangles for p…
- 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…
- 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 …
- Intention-Based Description (Intention-Based Graph Description, Purpose-Driven Description)
- An approach to generating accessible descriptions of visual content (particularly graphs and data visualisations) that focuses on communicating what the creator intended to convey rather than exhausti…
- Node-Link Diagram
- A visual representation in which discrete entities (nodes) are drawn as shapes such as circles or boxes and relationships between them are drawn as connecting lines or arrows (links/edges). Node-link …
- Non-Visual Drawing (Blind Drawing, Drawing Without Sight)
- The practice of creating graphical representations — such as diagrams, shapes, charts, or illustrations — without relying on visual feedback. Non-visual drawing can be accomplished through tactile met…
- Passive Exploration (System-Directed Presentation)
- An interaction paradigm in non-visual interfaces where a complete representation of information is presented to the user all at once, rather than being discovered through user-directed navigation. In …
- Raised-Line Drawing (Raised-Line Picture, Tactile Line Drawing, Embossed Line Drawing)
- A raised-line drawing is a tactile representation of a visual image created by producing elevated lines on a surface that can be felt by touch, enabling blind and visually impaired people to perceive …
- Reference Sonification (Audio reference tone, Origin tone)
- A sonification design pattern in which a fixed, recognisable audio tone represents a known landmark - typically the origin of a coordinate system or another anchor point - and can be re-played on dema…
- Volumetric Symbol (3D Symbol, Volumetric Icon)
- A small three-dimensional object used on a tactile or audio-tactile map to represent a category of place or facility — for example, a distinct shape for a restroom, elevator, information desk, or exhi…
