Immersive Virtual Reality(also: IVR, Immersive VR)

A form of virtual reality that uses head-mounted displays (HMDs) with near-full field of view, positional tracking, and often gesture-based controllers to create a sense of being physically present in a virtual environment. Unlike desktop VR or 360-degree video, immersive VR…

Information Architecture(also: IA)

The structural design of information environments, encompassing the organization, labeling, navigation, and search systems that help users find and manage information effectively. In digital accessibility, information architecture plays a critical role in ensuring that content…

Information Foraging(also: Information Foraging Theory)

A theoretical framework from cognitive science that models how people search for and navigate to information, drawing an analogy to animal foraging behaviour. Users assess "information scent" — cues like link text, headings, and page structure — to decide whether to continue…

Information Scent(also: Information Smell)

A concept from information foraging theory that describes the strength of cues in a user interface that indicate whether a particular path (link, button, menu item) will lead to desired information or functionality. Strong information scent means users can easily predict what…

Interaction Logging(also: Event Logging, User Interaction Logging, UI Event Logging)

The automated capture and recording of user interface events — such as clicks, keystrokes, focus changes, touch gestures, and scrolling — during a person's interaction with a digital system. In accessibility research and evaluation, interaction logging is valuable for…

Interface Personalisation(also: Interface Personalization, UI Personalisation, Adaptive Interface)

The ability for users to configure and customise the user interface of a digital system to match their individual needs, preferences, and abilities. In accessibility contexts, interface personalisation allows users to adjust settings such as text size, colour schemes, audio…

Intergenerational Design(also: Cross-Generational Design)

A design approach that considers the needs, preferences, and interaction patterns of users across different age groups and generations. Intergenerational design aims to create products and experiences that facilitate meaningful engagement between younger and older users rather…

Intrinsic Motivation

Intrinsic motivation refers to engaging in an activity for its inherent satisfaction rather than for external rewards or consequences. In accessibility and inclusive design, understanding intrinsic motivation is crucial for creating technologies that people genuinely want to…
