- Calibration-Free Interface (Zero-Shot Interface, Plug-and-Play Interface, Cross-User Model)
- An input system that works for a new user without any per-user training or calibration data, typically by relying on models trained on large multi-user datasets that capture enough physiological and b…
- Camera Phone (Smartphone Camera, Mobile Camera)
- A camera phone is a mobile phone equipped with a built-in image sensor, which in an accessibility context serves as the input device for a wide class of vision-based assistive applications. Modern sma…
- Camera-based assistive technology (Camera-based AT, Vision-based AT, VBAT)
- Assistive technologies that use cameras (typically smartphone cameras or smart glasses) combined with computer vision and AI to provide visual information to blind and low-vision users. Applications i…
- Cane Technique (White Cane Technique, Long Cane Technique)
- The set of physical methods a blind or low-vision person uses to manipulate a long white cane while traveling. Common techniques include the two-point touch (side-to-side sweeping, touching ground at …
- Caregiver Support (Carer Support, Family Support)
- Assistance, training, and resources provided to family members, paid carers, and other individuals who support people with disabilities in daily life. In the context of assistive technology, caregiver…
- Cause and Effect Software (Cause and Effect Games, Contingency Learning Software)
- Simple interactive software designed for users with significant cognitive or motor disabilities, where any input (such as pressing a switch) produces an immediate sensory response (visual, auditory, o…
- Cell Navigation (Table Cell Navigation, Cell-by-Cell Navigation)
- Cell navigation is a method of accessing tabular data non-visually by moving between individual cells using directional commands (up, down, left, right). Rather than reading a table linearly from top-…
- Chairable (Chair-based interface, Wheelchair-integrated technology)
- A design concept for input and output devices that are integrated directly into a wheelchair frame, enabling users to interact with assistive technology without requiring a separate smartphone, wearab…
- Chairable Technology (Chairable Input, Chairable Devices)
- Input devices and interactive technologies designed to integrate with the form of a wheelchair, analogous to how wearable technology fits with an individual's clothing. Chairable technology recognises…
- ChamBadge (Chambadge)
- A wearable accessible cell phone device developed as part of the Talking Braille ubiquitous computing system for indoor wayfinding. The ChamBadge combines a cell phone with a bone-conduction headset, …
- Charge-Coupled Device (CCD)
- An electronic light sensor used in cameras and scanners that converts light into electrical signals. CCDs capture images by accumulating electric charge in proportion to the intensity of light hitting…
- ChatGPT (GPT, OpenAI ChatGPT)
- ChatGPT is a conversational generative AI assistant developed by OpenAI, based on the GPT family of large language models. Users interact via a text chat interface and, in newer versions, through voic…
- Chatbot (Virtual Assistant, Conversational Agent, Dialog System)

- ChromeVox (ChromeVox Classic)
- ChromeVox is an open-source screen reader developed by Google, built as a Chrome browser extension and serving as the default screen reader for Chrome OS (Chromebooks). Unlike traditional screen reade…
- Clear Face Mask (Transparent Face Mask, Window Face Mask, See-Through Mask)
- A face covering that incorporates a transparent panel over the mouth area, allowing deaf and hard of hearing people to lip-read and observe facial expressions during conversation. Clear face masks eme…
- Click-Time Distribution (Timing Profile, Click Precision)
- A statistical model of when a switch user activates their switch relative to a target timing event, used to characterize the precision and consistency of a user's motor control. In the Nomon interface…
- Clicking Error (Click Slip, Selection Error)
- An unintended mouse input that occurs during the clicking phase of target selection, distinct from errors in cursor positioning. Common clicking errors include slipping off the target (the cursor move…
- Clutching (Clutch Mechanism, Clutch Gesture)
- In gesture- and motion-based input systems, a mechanism that lets the user temporarily disengage the recogniser so that everyday, non-communicative movements — reaching, adjusting posture, gesturing s…
- Co-Adaptive Design (Co-Adaptive Interaction, Mutual Adaptation)
- A design approach where both the technology and its users adapt to each other over time through ongoing interaction. Rather than designing a fixed system that users must learn to operate, co-adaptive …
