- Corrective feedback (Error correction feedback, Instructional feedback)
- Specific information provided to a user after an action that identifies what was done incorrectly and how to improve on the next attempt. In accessible interaction design, corrective feedback for blin…
- Cross-Filtering (Interactive Filtering, Linked Filtering)
- A dashboard interaction technique where applying a filter in one component (such as selecting a category in a chart or using a dropdown widget) automatically updates the data displayed in other relate…
- Cross-Modal Consistency (Multimodal Consistency, Cross-Modal Alignment)
- The alignment and coherence of information presented simultaneously through different sensory channels — such as touch and hearing, or vision and sound. In accessible education, cross-modal consistenc…
- Customizability (Customization, Personalization)
- The ability for users to modify and configure a system's interface, interaction methods, and behavior to match their individual needs and preferences. In accessibility contexts, customizability is a c…
- Customization Paradox (Paradox of Choice in Customization)
- The phenomenon where providing more customization options to reduce barriers paradoxically creates new barriers through increased cognitive load, decision fatigue, and distraction from the customizati…
- Degrees of Freedom (DoF, 3DoF, 6DoF)
- In virtual and extended reality, degrees of freedom refers to the number of independent movement axes available to a user within a virtual environment. Three degrees of freedom (3DoF) allows rotationa…
- Device Independence (Device-Independent Design, Input Agnostic Design)
- A web design principle that ensures content and functionality are accessible regardless of the input device or interaction method used to access them. Device-independent design avoids assumptions abou…
- Device-Dependent Event Handler (Device-Dependent Event, Mouse-Dependent Event Handler)
- An event handler in web development that is triggered only by a specific input device, such as a mouse click or touch gesture, rather than being accessible through multiple input methods. Device-depen…
- Dialog Act (Dialogue Act, Speech Act)
- A classification label representing the communicative intention behind a spoken or written utterance in a conversational system. In the context of accessible technology, dialog acts are used to interp…
- Direct Touch Mapping (DTM, Touch-to-Audio Mapping)
- An interaction technique in accessible touchscreen interfaces where the physical position of a user's finger on the screen corresponds directly to a position within the underlying content, such as a d…
- Disambiguation (Target Disambiguation, Touch Disambiguation)
- In accessible interface design, disambiguation is the process of resolving ambiguity when a user's input could correspond to more than one interactive target. This commonly occurs on touchscreens wher…
- Distraction Reduction (Distraction Removal, Distraction Minimization)
- Design strategies and technologies that minimize or eliminate elements that divert attention from primary content or tasks. In video accessibility for ADHD, distraction reduction involves identifying …
- Drag and Drop (DnD)
- An interaction pattern in which users select an on-screen object by pressing and holding, then move it to a new location before releasing. Drag and drop is widely used in visual programming environmen…
- Drone Accessibility (UAV Accessibility, Accessible Drone Piloting)
- The design and adaptation of unmanned aerial vehicles (drones) and their control interfaces to be usable by people with disabilities. This includes providing alternative input methods such as voice co…
- Dwell Selection (Dwell Click, Dwell Time Selection, Hover Click)
- An interaction technique where a user activates or selects an on-screen element by keeping a cursor, gaze point, or pointer within the target area for a specified duration (the dwell time), rather tha…
- Embodied Communication (Embodied Interaction)
- Communication that involves the whole body as a resource for meaning-making, including gestures, posture, facial expressions, gaze, touch, and physical movement through space. Embodied communication r…
- Embodied Interaction (Embodied Cognition in HCI)
- An approach to human-computer interaction that emphasizes the role of the physical body in how people engage with and understand technology. Embodied interaction recognizes that cognition is not purel…
- End-User Elicitation (Elicitation Study, User-Defined Gestures)
- A participatory research method where end users are asked to propose or create their own interaction techniques, gestures, or commands for a given system function, rather than having researchers presc…
- Enhanced Area Touch (Area Touch, Expanded Touch Area)
- A touchscreen interaction technique that enlarges the effective touch point from a single pixel to a larger circular area, expanding both the motor space (the physical area the user needs to target) a…
- Error Recovery (Error Correction, Error Handling)
- The process and mechanisms by which users can identify, understand, and correct errors that occur during interaction with a system. In accessibility contexts, error recovery is particularly important …
