3D Printing Pen (3D Pen)
A handheld device that extrudes a quick-cooling thermoplastic filament (commonly PLA, PCL, or ABS) through a heated nozzle, leaving raised, three-dimensional lines that solidify within seconds of bein…
Bimanual Exploration (Two-handed exploration, Bimanual tactile exploration)
The use of both hands in coordinated roles to perceive an object or space by touch. In blind and low-vision users, bimanual exploration is typically asymmetric: one hand (often the non-dominant) serve…
Conductive Filament (Conductive 3D printing filament, Conductive PLA)
A specialized 3D printing material that conducts electricity, enabling printed objects to interact with capacitive touchscreens. In accessibility applications, conductive filament can be embedded in o…
Detectable Warnings (Detectable Warning Surfaces, Tactile Warning Surfaces)
Detectable warnings are standardised tactile surface features installed on walking surfaces to alert people with visual impairments to hazards or transitions — most commonly the edge of a transit plat…
Digital Embroidery (Computerised Embroidery, Machine Embroidery)
Fabrication of stitched patterns on fabric using a computer-controlled embroidery machine that reads a digitised design file (e.g., DST, EXP) and drives a needle to produce precise, repeatable stitche…
Exploratory Procedures (EPs)
Exploratory procedures are stereotyped movement patterns that people use when examining objects through touch to identify specific properties. Defined by Lederman and Klatzky in tactile perception res…
Haptic Exploration (Tactile Exploration, Touch Exploration)
The process of acquiring spatial and object information through systematic touch and hand movements. Haptic exploration involves active manipulation and movement across surfaces to perceive shape, siz…
Haptic Virtual Reality (Haptic VR, Feelable Virtual Environment)
Haptic virtual reality refers to virtual environments that incorporate touch-based feedback, allowing users to feel virtual textures, shapes, and objects through force-feedback devices. Unlike visual-…
Monarch (Monarch Tactile Display, Dynamic Tactile Device)
The Monarch is a multi-line refreshable tactile display developed by HumanWare and the American Printing House for the Blind, representing a significant advancement in tactile display technology. Unli…
Pantograph (Haptic Pantograph)
A haptic input device that allows users to explore a two-dimensional surface by physically moving a stylus or finger pad across an exploration area, while receiving tactile feedback from an attached t…
Raised Line Drawing (Raised Line Graphic, Tactile Line Drawing, Swell Paper Drawing)
A graphic representation in which lines and shapes are physically raised above the surface of paper or another substrate so they can be perceived by touch. Raised line drawings are a fundamental tool …
Skin Stretch Display (Skin Stretch, Lateral Skin Deformation Display, STReSS)
A type of haptic display technology that produces tactile feedback by laterally stretching the skin of the user's fingertip, rather than using raised pins or vibration. Skin stretch displays typically…
Tactile Drawing (Tactile Picture Making)
The process of creating raised-line images that can be perceived through touch rather than vision. Tactile drawing can be done by blind or sighted people using methods such as drawing on swell paper w…
Tactile Exploration Strategy (Haptic Exploration Strategy, Touch Exploration Pattern)
A systematic approach or pattern that a person uses when exploring tactile graphics, maps, or other touch-based representations. Research has identified several distinct strategies: "following outline…
Tactile Image Exploration (Tactile Graphics Exploration, Haptic Image Exploration)
Tactile image exploration is the process by which blind or visually impaired users perceive and interpret graphical content through touch, typically by moving their fingers across raised-line drawings…
Tactile Imaging (Tactile Image, Tactile Image Conversion, Visual-to-Tactile Conversion)
The process of converting visual images into tactile representations that can be perceived through touch, enabling blind and visually impaired users to access graphical information. Tactile imaging in…
Tactile Perception (Cutaneous Perception, Touch Perception)
Tactile perception is the process of perceiving and interpreting information through the sense of touch, encompassing both cutaneous perception (sensing through the skin in a stationary process, detec…
Tactile Printer (Braille Embosser, Tactile Embosser)
A device that produces raised-line graphics and text on paper or other media, enabling people who are blind or have low vision to access visual information through touch. Tactile printers work by embo…
Tactile Rendering
The process of converting visual or spatial information into a tactile format that can be perceived through touch by blind or visually impaired users. Tactile rendering involves decisions about how to…
Tactile Stimulation (Tactile Feedback, Cutaneous Stimulation)
Tactile stimulation refers to the use of physical sensations delivered to the skin to convey information, typically through vibrations, pin arrays, textures, or pressure changes. In assistive technolo…
