- 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 Exhibit (Touch Exhibit, Hands-On Exhibit, Tactile Display)
- A museum or gallery exhibit designed to be explored through touch rather than sight, allowing visitors to physically interact with objects, models, or replicas. Tactile exhibits are particularly impor…
- Tactile Exploration (Haptic Exploration, Touch-Based Exploration)
- The process of perceiving and understanding objects, surfaces, or spatial layouts through systematic touch. For blind and low vision users, tactile exploration is a primary means of gathering spatial …
- 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 Feedback (Haptic Feedback, Touch Feedback)
- Physical sensations provided to a user through touch, including vibrations, textures, pressure, or resistance, that communicate information or confirm interactions. In accessibility, tactile feedback …
- Tactile Fidelity
- The degree of detail and accuracy in a tactile representation compared to the real object or concept it represents. High-fidelity tactile models include fine details, textures, and proportional accura…
- Tactile Graphic (Tactile Image, Raised-Line Graphic, Tactile Diagram)
- A physical representation of visual information that uses raised lines, textures, and relief to convey images, diagrams, maps, and other visual content through touch. Tactile graphics are essential fo…
- Tactile Graphic Reader (Tactile Graphic Display, Tactile Image Reader)
- A device that combines physical tactile graphics (raised-line images on paper) with digital audio feedback, enabling blind and visually impaired users to explore graphical content through touch while …
- Tactile Graphicacy (Tactile Literacy, Tactile Reading Skills)
- The learned ability to read, interpret, and create meaning from tactile images, maps, diagrams, and graphics through touch. Just as visual graphicacy is developed through exposure to visual images, ta…
- Tactile Graphics (Tactile Diagrams, Raised Graphics)
- Visual information represented in a raised or textured format that can be perceived through touch, enabling blind and low vision users to access charts, maps, diagrams, and illustrations. Tactile grap…
- Tactile Graphics (Tactile Images, Tactile Diagrams, Raised-Line Graphics)
- Visual information represented in a form that can be perceived through touch, enabling people who are blind or have low vision to access images, diagrams, maps, charts, and spatial layouts. Tactile gr…
- Tactile Graphics Assistant (TGA)
- A software tool developed at the University of Washington that automates parts of the tactile graphics translation process to help specialists more efficiently convert printed images into tactile form…
- Tactile Guide (Tactile Jig, Tactile Fixture)
- A physical modification attached to equipment or tools that provides tactile directional feedback to guide a user through a task without relying on vision. In manufacturing and assembly settings, tact…
- Tactile Icon (Tactile Symbol, 3D Icon, Raised Icon)
- A small raised or three-dimensional symbol placed on a tactile map or diagram that represents a real-world object, location, or concept through touch. Tactile icons can be abstract (geometric shapes r…
- Tactile Ideation (Tactile Design Workshop, Non-Visual Ideation)
- A design methodology adapted for people with visual disabilities that replaces visual ideation techniques (such as sketching, post-it notes, and ideation cards) with tactile and auditory alternatives.…
- Tactile Image (Tactile Graphic, Tactile Picture, Touch Image)
- A tactile image is a raised or textured representation of a visual image designed to be perceived through touch rather than sight. Tactile images can be produced through various methods including embo…
- 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 Interface (Haptic interface, Touch-based interface)
- An input/output interface that conveys information through the sense of touch — using vibration, pressure, skin stretch, temperature, or physical shape change. In navigation for blind people, tactile …
- Tactile Learning (Haptic Learning, Touch-Based Learning)
- An educational approach that uses the sense of touch to convey information, explore concepts, and develop understanding. For blind and low vision learners, tactile learning encompasses reading Braille…
