- Graphic Input Device (Drawing Input Device, Graphic Tablet)
- A hardware device used to input and manipulate visual graphics on a computer, including digital drawing pads (digitizer tablets), styluses, mice, trackballs, touchscreens, and specialized assistive de…
- Graphic Transcription (Image Transcription, Accessible Graphic Transcription)
- The process of converting visual graphics (charts, maps, floor plans, diagrams) into formats accessible to blind and visually impaired users, such as tactile graphics, audio descriptions, or interacti…
- Graphical User Interface (GUI)
- A type of computer interface that uses visual elements such as windows, icons, menus, and pointers to allow users to interact with software, as opposed to text-based command-line interfaces. GUIs pres…
- Gravity Well (Target Attraction, Sticky Targets, Snap-to-Target)
- An interaction filtering technique that warps the cursor space around interactive targets (such as buttons or links), creating attractive basins that pull the cursor toward the nearest target. This ma…
- Grid Display (Symbol Grid, Grid-Based AAC)
- A common AAC layout format that presents communication options as symbols, icons, or words arranged in a grid pattern of rows and columns. Grid displays are widely used in speech-generating devices an…
- Guide Runner (Sighted Guide Runner, Running Guide)
- A sighted person who accompanies a blind or visually impaired runner during training or competition, providing verbal navigation cues and physical guidance typically through a tether connecting the tw…
- Hand Tracking (Gesture Tracking, Hand Gesture Recognition)
- A technology that detects and tracks the position, orientation, and movements of a user's hands and fingers without requiring physical controllers, typically using cameras and computer vision algorith…
- Haptic (Haptic feedback, Haptic interface)
- Relating to the sense of touch as a means of interaction between a user and a device. Haptic interfaces include braille displays that raise and lower pins to represent text, vibration motors in mobile…
- Haptic Communication (Social Haptics, Tactile Communication, Haptic Interaction)
- A method of conveying information through touch-based signals, vibrations, or physical patterns on the body. Haptic communication is particularly important for individuals with deafblindness or other …
- Haptic Controller (Haptic Interface, Tactile Controller)
- An input device that uses touch-based interaction, typically through buttons, pads, or surfaces that can be pressed, tapped, or manipulated. In music technology, haptic controllers include devices lik…
- Haptic Display (Tactile Display, Pin-Matrix Display, Refreshable Tactile Display)
- A device that conveys information through the sense of touch by dynamically raising and lowering physical elements (typically pins) to create tactile patterns. In accessibility, haptic displays range …
- Haptic Feedback (Tactile Feedback, Touch Feedback)
- Information conveyed through the sense of touch, typically using vibrations, force, or texture changes to communicate data or system states to a user. In accessibility, haptic feedback provides non-vi…
- Haptic Feedback (Tactile Feedback, Haptics)
- Technology that communicates information through the sense of touch, using vibrations, pressure, or motion applied to the user's body. In accessibility, haptic feedback provides a non-visual, non-audi…
- Haptic Glove (Data Glove, Tactile Glove, Wearable Haptic Device)
- A wearable device worn on the hand that provides tactile feedback through vibration motors, piezoelectric actuators, pin arrays, or other mechanisms embedded in the fingers and palm. In accessibility …
- Haptic Graphics (Dynamic Tactile Graphics, Refreshable Haptic Graphics)
- Graphical information presented through the sense of touch, typically on refreshable displays or touchscreen devices. Unlike static tactile graphics (embossed paper or thermoform), haptic graphics can…
- Haptic Guiding (Force-Based Guiding, Haptic Navigation)
- A collaborative interaction technique where one user physically guides another user's cursor or pointer through force feedback, allowing spatial information to be communicated through touch rather tha…
- Haptic Handle (Tactile handle)
- A grip on a mobility or guidance device (robot, smart cane, haptic rein, etc.) that conveys information to the user through touch — typically via buttons, vibrotactile feedback, or physical coupling t…
