- Electrolarynx (Artificial Larynx, Electronic Larynx)
- A handheld, battery-powered device that produces voice for people who have lost their larynx. The device is held against the neck or cheek and generates vibrations that travel through the throat tissu…
- Electrolarynx (Artificial Larynx, Electric Larynx, EL Device, Throat Vibrator)
- A handheld battery-powered device that produces mechanical vibrations to generate speech for people who have lost their larynx (voice box), typically due to laryngeal cancer surgery. The device is hel…
- Electromagnetic Actuation (EM Actuation)
- A method of producing physical movement using electromagnetic fields generated by electric coils. In accessibility contexts, electromagnetic actuation is used to move tactile elements — such as magnet…
- Electromagnetic Tracking (Magnetic Tracking, 6-DOF Tracking)
- Electromagnetic tracking is a position and orientation sensing technology that uses electromagnetic fields to determine the location and rotation of a sensor in three-dimensional space. Systems like t…
- Electromyography (EMG, Electromyogram)
- Electromyography (EMG) is a technique for measuring the electrical activity produced by muscles when they contract or are at rest. In accessibility and assistive technology, EMG sensors placed on the …
- Electronic Assistive Technology (EAT, Electronic AT)
- Computer-based devices and systems that enable people with severe disabilities to perform tasks they would otherwise be unable to accomplish, including communication, environmental control, mobility, …
- Electronic Curb-Cut Effect (Digital Curb-Cut Effect, Curb-Cut Effect)
- The phenomenon where accessibility features originally designed for people with disabilities end up benefiting a much wider population. Named after physical curb cuts in sidewalks — originally mandate…
- Electronic Textbook (E-Textbook, Digital Textbook, Interactive Textbook)
- A digital version of an educational textbook that goes beyond simply reproducing printed content on screen by offering interactive features such as searchable text, bookmarking, embedded exercises and…
- Electronic Travel Aid (ETA)
- An electronic device designed to help blind or visually impaired people navigate their environment by detecting obstacles and conveying spatial information through non-visual feedback such as audio cu…
- Electrooculogram (EOG, Electrooculography)
- The electrooculogram (EOG) is a technique for measuring the electrical potential difference between the front and back of the eye using surface electrodes placed around the eyes. This corneal-retinal …
- Electropalatography (EPG, Dynamic Palatography, Palatography)
- A technique for recording tongue-palate contact during speech using an artificial palate fitted with electrodes. When the tongue touches the palate, it completes a low-amperage electrical circuit that…
- Electrotactile (Electrotactile Stimulation, Electrical Tactile Stimulation)
- A form of tactile feedback that applies controlled electrical current to stimulate touch nerve endings in the skin, creating sensations of pressure, tingling, or texture. Electrotactile displays can a…
- Electrotactile Feedback (Electrotactile, Electrical Tactile Stimulation)
- A form of haptic feedback that uses controlled electrical current applied directly to the skin or through a thin insulating layer to generate tactile sensations. Unlike vibrotactile feedback (which us…
- Element Detection (UI Element Detection, Widget Detection, Object Detection)
- The task of automatically identifying the locations and types of user interface components (such as buttons, text fields, images, and checkboxes) from a screenshot using computer vision models. Elemen…
- ElevenLabs
- A commercial AI voice platform that generates realistic synthetic speech and voice clones from text. ElevenLabs is used in accessibility contexts for producing narrated video voiceovers, audiobook-sty…
- Elicitation Study (Gesture Elicitation Study)
- An elicitation study is a user research method in which participants are shown the effect of an action (called a referent) and asked to propose the input or gesture (called a sign) that should cause i…
- Eligibility Theatre
- A term coined by Curtis et al. (2026) to describe the performance of visible, narrowly-framed disability that claimants are forced to stage in order to satisfy bureaucratic and algorithmic expectation…
