- Gamification (Game-Based Learning)
- The application of game design elements and principles in non-game contexts to increase engagement, motivation, and learning outcomes. In reading accessibility, gamification has been used in literacy …
- Gamification
- The application of game design elements — such as points, rewards, competition, collection mechanics, and progress tracking — in non-game contexts to increase engagement and motivation. In accessibili…
- Gamification (Games with a Purpose, GWAP)
- The application of game design elements — such as points, levels, leaderboards, and time challenges — to non-game tasks in order to increase engagement and motivation. In accessibility, gamification h…
- Gamified evaluation (Game-based assessment, Gamified testing)
- A research methodology that incorporates game design elements — such as challenges, scoring, progressive difficulty, and rewards — into the evaluation of technology or user performance, to increase pa…
- Gaming accessibility (Game accessibility, Accessible gaming)
- The design and development of video games and gaming experiences that can be enjoyed by people with a wide range of abilities, including those with motor, sensory, cognitive, and communication disabil…
- Gaokao (National College Entrance Examination)

- Gatekeeping (Access Gatekeeping)
- Gatekeeping in accessibility contexts refers to practices, policies, or attitudes that create unnecessary barriers to disabled people receiving the accommodations or access they need. This can include…
- Gaussian Blur (Gaussian Filter)
- An image processing technique that smooths an image by averaging pixel values using a Gaussian (bell-curve) weighted function, creating a soft, out-of-focus appearance. In video accessibility, Gaussia…
- Gaussian Mixture Model (GMM)
- A Gaussian Mixture Model (GMM) is a probabilistic model that represents data as a weighted combination of multiple Gaussian (normal) distributions. Each component Gaussian has its own mean and covaria…
- Gaze (Eye Gaze, Gaze Direction, Point of Regard)
- The direction in which a person is looking, typically measured as the point of visual fixation on a display or in a physical environment. Gaze tracking technology captures where users look and for how…
- Gaze Fixation (Eye Fixation, Visual Fixation)
- The act of maintaining one's gaze steadily on a specific point or target, as opposed to saccadic eye movements between points. In gaze-based assistive technology, gaze fixation is the primary mechanis…
- Gaze Input (Eye Tracking Input, Gaze-Based Interaction, Eye Control)
- An input method that uses eye-tracking technology to detect where a user is looking, enabling interaction with digital interfaces through eye movements such as fixation (dwelling on a target), smooth …
- Gaze Interaction (Gaze-Based Interaction, Gaze Input, Eye Gaze Control)
- Gaze interaction is a method of controlling computers and devices by tracking where a person is looking on the screen. Using eye-tracking technology, the system detects the user's point of gaze and tr…
- Gaze Reinstatement (Gaze Reinstatement Effect, Looking-at-Nothing Paradigm)
- Gaze reinstatement is the cognitive phenomenon in which a person mentally recalling or imagining a previously seen scene reproduces, on a blank or unrelated surface, eye movement patterns similar to t…
- Gaze Switching (Visual Attention Switching, Split Attention)
- The act of shifting visual focus between two or more information sources, such as between captions and presentation slides in a classroom, or between a sign language interpreter and a speaker. Gaze sw…
- Gaze Tracking (Eye Tracking, Eye Gaze Tracking)
- Technology that measures and records eye movements to determine where a person is looking, for how long, and in what pattern. In low-vision research and rehabilitation, gaze tracking can reveal visual…
- Gaze Typing (Eye Typing, Gaze-Based Text Entry, Eye-Typing)
- A text input method that uses eye tracking technology to allow users to type by looking at keys on a virtual on-screen keyboard. The most common technique is dwell-based selection, where the user fixa…
- Gaze-Based Communication (Eye Gaze Communication, Gaze-Based AAC)
- A form of augmentative and alternative communication that uses eye movement tracking to enable people with severe motor and speech impairments to select words, phrases, symbols, or commands on a scree…
- Gaze-Based Interaction (Gaze Input, Eye-Gaze Interaction, Gaze Control)
- An interaction method where users control digital interfaces by directing their visual gaze at on-screen targets, typically detected through eye tracking or head orientation tracking. In accessibility…
- Gazepoint (Gaze Point, Point of Gaze)
- The specific point on a screen or surface where a person is looking at any given moment, as determined by an eye tracking system. The gazepoint is calculated from the gaze vector — the line extending …
