- Human-in-the-Loop (HITL)
- An approach to AI system design and evaluation that incorporates human judgment, feedback, and oversight at critical points in automated processes. In accessibility contexts, human-in-the-loop methodo…
- Human-like trust in AI (Anthropomorphic trust)
- The phenomenon where users develop trust in AI systems based on their human-like qualities — such as natural voice, conversational style, emotional expressiveness, and social behaviors — rather than t…
- Humanoid Robot (Humanoid)
- A robot whose physical form approximates a human body, typically with a head, torso, two arms, and (in bipedal designs) two legs. Humanoid robots are studied in accessibility research as embodied demo…
- Humming Interface (Control-by-Humming, Hum-Based Interface)
- A human-computer interaction method that uses hummed pitch patterns as control signals for operating devices. In a humming interface, a pitch detection algorithm analyses the user's hummed input, segm…
- HyDE (Hypothetical Document Embeddings)
- A query-expansion technique for retrieval-augmented generation in which an LLM is first asked to generate a hypothetical answer to the user's question, and that hypothetical answer — rather than (or a…
- Hybrid Captioning (AI-Augmented Captioning, Blended Captioning)
- A captioning approach that combines human-generated captions with AI-powered correction or enhancement to achieve higher accuracy than either method alone. Hybrid systems leverage the reliability and …
- Hybrid Craft (Digital Craft, Computational Craft)
- A making practice that combines traditional hand-craft techniques (embroidery, weaving, quilting, ceramics, woodworking) with digital fabrication tools such as computerised embroidery machines, laser …
- Hybrid Interaction (Multimodal Hybrid Approach)
- An interaction design approach that combines multiple input and output modalities, allowing users to switch between them based on task requirements, context, and personal preferences. In accessibility…
- Hybrid Search (Hybrid sign-language search)
- A sign-language dictionary search pattern that combines search-by-video (a user performs the sign into a camera for sign recognition to match) with search-by-feature (manual filtering of the candidate…
- Hybrid Space (Blended Space, Hybrid Community Space)
- A community or program environment that combines both in-person and online elements, not necessarily simultaneously, to create a more accessible and inclusive experience. In accessibility contexts, hy…
- Hybrid automaton (Hybrid state machine)
- A computational model that combines discrete state transitions with continuous dynamics, used in interactive systems to govern object behaviours based on multiple users's simultaneous inputs. In colla…
- Hydrocephalus (Hydrocephaly, Water on the Brain)
- A condition characterized by an abnormal accumulation of cerebrospinal fluid within the ventricles of the brain, causing increased intracranial pressure and enlargement of the head. Hydrocephalus can …
- Hyper-aged Society (Super-aged Society)
- A country or region where people aged 65 and over make up more than 21% of the total population. The term distinguishes extreme demographic aging from merely "aging" (7%+) or "aged" (14%+) societies. …
- Hyperactivity
- A core symptom of ADHD characterized by excessive movement, restlessness, difficulty remaining seated or still, and feeling driven as if by a motor. In adults, hyperactivity often manifests as interna…
- Hyperacusis (Decreased sound tolerance)
- A hearing condition in which everyday sounds are perceived as uncomfortably or painfully loud, even at volume levels that are tolerable for most people. Hyperacusis involves a reduced tolerance for th…
- Hyperarticulation (Clear Speech, Over-Articulation)
- A speaking style in which a person exaggerates the clarity of their pronunciation by moving their tongue and mouth to more extreme positions, producing more distinct vowel and consonant sounds. Hypera…
- Hyperfixation
- Hyperfixation is an intense, prolonged focus on a single activity, topic or interest to the exclusion of other tasks and bodily needs, commonly associated with ADHD and autism. Unlike hyperfocus, whic…
- Hyperfocus (Hyper-Focus, Flow State)
- A state of intense, sustained concentration on a task or activity, commonly experienced by people with ADHD and other neurodivergent conditions. During hyperfocus, individuals may become deeply absorb…
- Hypergraph
- A mathematical structure that generalises both trees and graphs by allowing edges (called hyperedges) to connect any number of nodes rather than being limited to exactly two. In the context of accessi…
- Hypermedia
- An extension of hypertext that incorporates multimedia content — audio, video, images, and animation — alongside text, all linked in a non-linear structure. What distinguishes hypermedia from hypertex…
