Camera Aiming (Camera Pointing, Camera Guidance)
The challenge blind users face in correctly positioning and aiming a camera to capture the intended visual content. Since blind users cannot see the camera viewfinder, they may inadvertently capture t…
Camera Framing (Photo Framing, Object Framing)
The act of positioning a camera so that the intended subject is properly captured within the image frame — not cropped, not too small, and centered enough for clear identification. Camera framing pres…
Camera Guidance (Camera Aiming Assistance, Framing Assistance)
Non-visual feedback systems that help blind users position a camera to capture usable images of documents, objects, or scenes. Guidance may include spoken directional instructions (e.g., "move up", "m…
Camera Mouse (Head-Controlled Mouse Pointer, Head Tracking Mouse)
A computer-vision-based mouse-replacement system that tracks a user's head motion through a standard webcam to control the mouse pointer on screen. Developed at Boston University by Margrit Betke and …
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…
Camouflaging (Masking, Social Camouflage, Autistic Masking)
Camouflaging, also known as masking, is the conscious or unconscious suppression of autistic traits and adoption of neurotypical behaviors in order to fit into social situations. This can include forc…
Camouflaging Autistic Traits Questionnaire (CAT-Q)
A 25-item self-report questionnaire developed by Hull, Mandy, Lai, Baron-Cohen and colleagues (2019) for adults to self-assess autistic masking (camouflaging) behaviours. Items are rated on a 7-point …
Candlewick Knot (Candlewick Stitch)
An embroidery stitch that creates raised, textured bumps or knots on the fabric surface. Candlewick knots produce one of the roughest and most tactilely distinctive textures available in machine embro…
Cane Simulation (Virtual Cane, White Cane Simulation)
A virtual reality application that simulates the experience of using a white cane (long cane) for navigation, allowing blind users to explore virtual environments through haptic feedback. In a cane si…
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 …
Canonical MathML (Canonical Mathematical Markup Language)
A restricted, normalised subset of MathML in which mathematical structures are represented in a deterministic, unambiguous way. While standard Presentation MathML allows the same mathematical expressi…
Canonical Syllable (Canonical Babbling, Well-Formed Syllable)
A canonical syllable is a well-formed syllable in infant babbling that consists of a consonant-like closure (closant) produced by an oral cavity constriction followed by a vowel-like opening (vocant).…
Capabilities approach (Capability approach, Human capabilities framework)
A philosophical framework developed by Amartya Sen and Martha Nussbaum that evaluates well-being and justice based on what people are actually able to do and be, rather than on the resources they poss…
Capability Sensitive Design
A design approach, proposed by Ilse Oosterlaken, that takes human diversity morally seriously and evaluates technologies by how they actually expand or constrain the real opportunities (capabilities) …
Capability model (User capability profile)
A structured representation of an individual user's abilities across relevant dimensions such as sight, hearing, mobility, and cognition. In accessibility and adaptive interface design, capability mod…
Capacitive Touch (Capacitive Sensing, Capacitive Touch Sensing)
A touch detection technology that works by measuring changes in electrical capacitance when a conductive object, such as a human finger, comes near or contacts an electrode surface. The finger and ele…
Capacitive Touchscreen (Capacitive Touch Display, Cap Touch)
A capacitive touchscreen is a type of display that detects touch input by sensing changes in the electrical field caused by the conductivity of a human finger or conductive stylus. Unlike resistive to…
Capacitive marker (Capacitive fiducial, Conductive marker)
A conductive structure embedded in a physical object that registers as a touch point on a capacitive touchscreen, enabling the device to detect the object's position and orientation without cameras or…
Capacity Building (Research Capacity Building, Capability Development)
The process of developing and strengthening the skills, resources, and infrastructure that enable individuals, communities, and organizations to carry out research, develop technologies, and advocate …
