DeafSpace (Deaf Space, Deaf architecture)
A set of architectural and environmental design principles developed by architect Hansel Bauman in collaboration with the Deaf community at Gallaudet University, grounded in the sensory and spatial ex…
Design Probe (Technology Probe, Design Provocation)
A research method in which a functional or semi-functional prototype is deployed with participants not primarily to test usability, but to provoke discussion, elicit design insights, and explore futur…
Design System (Component Library, UI Kit)
A collection of reusable components, patterns, guidelines, and assets that together define the visual language and interaction standards for a product or organization. Design systems typically include…
Design for All (DfA, Design pour Tous)
A European design philosophy that aims to create products, environments, and services usable by the widest possible range of people without adaptation or specialized design. Originating from the Europ…
Design for Social Accessibility (Social accessibility framework, DSA)
A design framework that extends traditional accessibility approaches by addressing not only the functional usability of technology but also the social contexts and implications of its use. Design for …
Design justice
A framework that centers the perspectives and leadership of people most affected by design outcomes, challenging traditional design processes that often reinforce existing power structures. Coined and…
Design probe (Technology probe, Cultural probe)
A research methodology in human-computer interaction where a prototype or artefact is deployed with participants not primarily to test usability, but to provoke reflection, surface unanticipated needs…
Design space (Interaction modality)
A medium, physical or abstract, through which a user and a device exchange information. The visual design space uses sight (screens, displays), the sonic design space uses hearing (speech, earcons, mu…
Design space properties
The characteristics of information within a design space, classified by the type of cognitive processing they require. Direct properties relate to perception and automatic processing — colour, brightn…
Design space structure
A framework characterising how raw information is organised within a design space. Nesbitt classifies information conveyed through sensory channels as nominal (categorical, such as labels), quantitati…
Diegetic Prototype (Diegetic Prop)

Ecological Metaphor (Ecological Validity, Ecological Mapping)
A design principle in sonification and auditory display where the mapping between data and sound aligns with users' real-world sensory and cognitive experience. For example, mapping obstacle distance …
Emotional Design
A framework developed by Don Norman describing how people evaluate and form attachments to products through three cognitive levels: visceral (immediate sensory and aesthetic responses), behavioral (fu…
Fidelity
An expression of how accurately a representation reproduces its source. A photograph is a high-fidelity visual representation of a scene but loses depth, sound, and smell. In accessibility and content…
Functional accessibility
The degree to which a device or interface is usable by a specific user or user profile, either directly or through the addition of assistive technology. A system is functionally accessible for a given…
Functional affordance
A design concept introduced in receptive design methodology that describes what a product or interface enables a user to do based on specific body functions, rather than general ability assumptions. U…
