Haptic Technology(also: Haptics, Touch Technology)

Technology that creates tactile experiences through the application of forces, vibrations, or motions to the user, enabling interaction through the sense of touch. Haptic technologies range from simple vibration motors in smartphones to sophisticated force-feedback devices and…

Head-Mounted Display (HMD)(also: HMD, Head-Mounted Display, Smart Glasses)

A display device worn on the head that places visual content in front of one or both eyes. Head-mounted displays include AR smart glasses (like Vuzix Blade), VR headsets, and mixed reality devices. In accessibility applications, HMDs can present captions, sign language…

Home Automation(also: Domotics, Smart Home Automation)

The use of technology to automatically control household systems and appliances such as lighting, heating, ventilation, security, and entertainment. Home automation systems use sensors, timers, and programmable rules to operate devices without manual intervention. For people…

Huffman Coding(also: Huffman Algorithm, Huffman Tree)

A data compression algorithm that assigns shorter codes to more frequently occurring symbols and longer codes to less frequent ones, producing an optimal prefix-free encoding. In accessibility and AAC research, Huffman coding has been applied to the design of scanning interfaces…

Human Computation

A computing paradigm in which humans perform tasks that computers cannot yet do reliably, often embedded within systems that combine human and machine capabilities. The classic example is reCAPTCHA, which used human text recognition to digitise books while verifying users were…

HyDE(also: 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 alongside) the raw query — is embedded and used to search the document index.…

Hybrid Space(also: 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, hybrid spaces address barriers such as geographic distance, mobility limitations,…
