Tactilization (Tactile Rendering, Haptic Rendering)
The process of converting visual or abstract information into tactile representations that can be perceived through the sense of touch. In accessibility, tactilization transforms content such as web p…
Tacton (Tactile Icon, Vibrotactile Pattern)
A structured and abstract vibrotactile message designed to communicate complex information to users non-visually, analogous to how icons communicate information visually or earcons communicate through…
Tactor (Vibrotactile Actuator, Tactile Actuator, Vibration Motor)
A small electromechanical device that produces vibrations against the skin to convey information through the sense of touch. Tactors are the fundamental components of tactile displays and wearable hap…
TalkBack (Android TalkBack, Google TalkBack)
The built-in screen reader for Android devices, developed by Google as part of the Android Accessibility Suite. TalkBack provides spoken feedback, vibration, and other audible cues to help blind and v…
Talking Browser (Talking Web Browser, Speaking Browser)
A historical term for a specialised web browser that converts on-screen content into synthesised speech, enabling blind and low-vision users to browse the web through audio rather than through a separ…
Talking Head (Virtual Talking Head, Animated Face, 3D Talking Head, Virtual Speech Tutor)
A talking head is a computer-generated 3D or 2D animated representation of a human face and articulatory system that produces visible speech movements synchronised with audio output. In accessibility …
Talking Lights
Talking Lights is a commercial location-signalling system that modulates ordinary fluorescent light fixtures to transmit an inaudible digital signal, which a hand-held receiver carried by a blind user…
Talking Signs (Talking Sign)
An assistive technology system that uses infrared (IR) frequency modulated voice signals to transmit spoken information about signage to people with vision loss. Developed by the Smith-Kettlewell Eye …
Tangible Interface (Tangible User Interface, TUI)
A user interface that uses physical objects as representations and controls for digital information, allowing users to interact through touch and manipulation of tangible artifacts. In accessibility c…
Tangible Programming (Physical Programming, Tangible Coding, Tactile Programming)
A programming approach that uses physical objects — such as blocks, cards, or robots — that users can manipulate with their hands to create programs, rather than typing code or dragging on-screen elem…
Tangible interaction (Tangible user interface, TUI, Physical computing)
An interaction paradigm in which users manipulate physical objects and materials to interact with digital information, bridging the gap between the physical and digital worlds. Tangible interfaces lev…
Task Prompting (Task Prompting System, Cognitive Prompting)
Task prompting is an assistive technology approach that provides step-by-step instructions or cues to guide individuals with cognitive impairments through multi-step tasks. Prompts can be delivered th…
Teachable Object Recognition (Teachable Object Recognizer, TOR, Personalized Object Recognition)
A machine learning approach that allows users to train an object recognition system to identify their own personal items by providing a small number of training examples, typically photos or videos. T…
Technology Abandonment (Device Abandonment, Technology Discontinuance)
The phenomenon where users stop using a technology or assistive device after initial adoption, often due to poor usability, lack of perceived benefit, inadequate training, or misalignment with actual …
Technology Acceptance (Technology Adoption, TAM)
The process by which individuals evaluate, adopt, and integrate new technology into their routines, often modeled through frameworks like the Technology Acceptance Model (TAM) which emphasizes perceiv…
Technology Acceptance Model (TAM)
A theoretical framework originally developed by Fred Davis in 1989 that explains how users come to accept and use a technology. TAM posits that technology adoption depends on two primary factors: perc…
Technology Adoption (AT Adoption, Technology Uptake)
The process by which individuals begin using and integrating new technology into their daily routines. In accessibility contexts, technology adoption encompasses the decision to acquire assistive tech…
Technology Dependency (Tech Dependency, Digital Dependency)
The state of relying on technology to perform tasks that one might otherwise accomplish independently, or the risk that technology use persists beyond the original need. In disability and accessibilit…
Technology Ecosystem (Tech Ecosystem)
The interconnected network of hardware, software, services, infrastructure, professionals, and support systems that collectively determine whether a technology can be effectively used and sustained. I…
Technology interdependence (Technological interdependence, Multi-tool strategy)
The strategic use of multiple complementary technologies in combination to accomplish tasks that no single tool can fully support. For people with disabilities, technology interdependence is particula…
