Reading accessibility(also: Readable content, Text accessibility)

Recreational Accessibility(also: Leisure Accessibility)

Recreational Exploration(also: Wandering exploration, Exploratory navigation, Open-ended exploration)
Movement through an environment driven by interest, curiosity, or enjoyment rather than by a fixed destination — for example wandering a museum, browsing a shopping mall, or exploring a neighbourhood. For blind and low-vision people, recreational exploration is harder to support…
STEM(also: STEM Education, Science Technology Engineering and Mathematics)
An acronym for Science, Technology, Engineering, and Mathematics, used to describe educational disciplines and career fields. In accessibility contexts, STEM engagement is particularly important because people with disabilities are severely underrepresented in these fields.…
STEM accessibility(also: Accessible STEM education)
The practice of making science, technology, engineering, and mathematics education and activities accessible to people with disabilities. STEM fields present particular accessibility challenges because they rely heavily on visual representations (diagrams, graphs, microscopy),…
Selective disclosure(also: Contextual disclosure, Situational disclosure)
The practice of revealing disability identity to specific people or in specific contexts while keeping it private in others, based on a continuous assessment of safety, trust, relevance, and potential consequences. Most people with invisible disabilities practice selective…
Self-presentation(also: Impression management, Identity management)

The provision of guidance, troubleshooting, and learning resources to help older adults use digital technologies effectively. Research identifies two key dimensions: self-reliant support (online tutorials, video guides, built-in help features, trial-and-error) and social support…
Telepresence robot(also: Telepresence, Remote presence robot)
A mobile robotic device that enables a remote user to have a physical presence in a distant location, typically featuring a screen displaying the user's face, a camera, microphone, speaker, and wheels for navigation. In educational and workplace accessibility contexts,…
