- Physical Guidance (Hands-On Guidance, Physical Assistance)
- A body movement teaching technique in which an instructor physically moves or positions a student's body to demonstrate correct form, rhythm, or placement. Physical guidance is widely used in teaching…
- Presentation Accessibility (Slide Accessibility, Accessible Presentations)
- The practice of designing and delivering slide-based presentations so that all audience members, including those with disabilities, can access the content. Key principles include verbally describing a…
- Procedural Feedback System (Process-Oriented Guidance System)
- An assistive technology paradigm that provides dynamic, step-by-step support throughout complex multi-step tasks rather than addressing isolated moments of need. Unlike traditional assistive tools tha…
- Proprioception (Proprioceptive Sense, Body Position Sense)
- The body's ability to sense its own position, movement, and orientation in space without relying on vision. Proprioceptive information comes from sensory receptors in muscles, tendons, and joints that…
- Refreshable Graphics Display (Tactile Graphics Display, Dynamic Tactile Display)
- A device that presents tactile graphics and diagrams through an array of pins that can be individually raised or lowered to create dynamic, changeable tactile patterns. Unlike static tactile graphics …
- SMILES (Simplified Molecular-Input Line-Entry System)
- A text-based notation system that represents chemical molecular structures as short character strings, making them both machine-readable and human-readable. For accessibility, SMILES is significant be…
- Sighted Assistance (Visual Interpreting, Remote Sighted Assistance)
- Sighted assistance refers to services that connect blind or low-vision individuals with sighted people who can provide visual information on demand, typically through a live video call from a smartpho…
- Sighted Guide (Sighted Guide Technique, Human Guide)
- A technique in which a sighted person assists a blind or low vision individual with navigation and orientation by serving as a visual reference and mobility aid. In physical settings, the blind person…
- Sighted Memory (Visual Memory, Sighted Recall)
- A mental representation of a physical environment developed through past visual experience, used by people who lose their sight later in life to navigate and understand spaces they previously knew vis…
- Social Distancing (Physical Distancing)
- The practice of maintaining a minimum physical distance from other people to reduce the transmission of infectious diseases, widely adopted during the COVID-19 pandemic with recommended distances of a…
- Spatial Memorization (Spatial Memory Strategy, Kitchen Layout Memory)
- A compensatory strategy used by blind and low vision individuals to navigate and interact with environments by memorizing the spatial layout of objects, tools, and landmarks. In cooking, spatial memor…
- Tactile Ballot (Tactile Voting Device, Tactile Template, Tactile Sleeve, Braille Sleeve)
- A physical overlay, sleeve, or template placed over a paper ballot that provides raised, cut-out, or braille markings aligned with ballot boxes so that blind and low-vision voters can locate candidate…
- 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…
- Tactile Literacy (Tactile Reading Skills)
- The ability to interpret, understand, and create information conveyed through the sense of touch, including the skills needed to read tactile graphics, maps, diagrams, braille, and other raised repres…
- Tactile Modeling (Tactile Demonstration, Touch Demonstration)
- A body movement teaching technique where a blind or low vision student explores and inspects a demonstrator's body position through touch, allowing them to understand poses, movements, and form that w…
- Tactile Replica (3D Replica, Touchable Replica, Haptic Replica)
- A physical reproduction of an artwork or exhibit object, often created using 3D printing or traditional sculpting techniques, designed to be touched and explored by hand. Tactile replicas are a key ac…
- Tactile-First Strategy (Touch-Based Strategy, Tactile-First Approach)
- An approach to completing tasks that prioritizes touch and physical sensation as the primary sensory channel for guidance, feedback, and assessment. In accessibility contexts, tactile-first strategies…
- Teachable Object Recognition (Teachable Object Recognizer, TOR, Personalized Object Recognition)
- A machine learning approach that allows users to train an object recognition system to identify their own personal items by providing a small number of training examples, typically photos or videos. T…
- Touch Reader (Tactile Reader, Tactile Graphics Reader)
- A person who reads and interprets information through touch, particularly tactile graphics, raised line drawings, and braille. Touch readers include blind and low-vision individuals who access spatial…
- Vibro-Audio (Vibrotactile Audio, Vibro-Tactile)
- Vibro-audio is a multimodal interaction technique that combines vibration feedback from a device's built-in motor with auditory cues to convey information non-visually. On touchscreen devices, vibro-a…
