- Affective Touch (Social Touch, Emotional Touch)
- The emotional and social dimension of touch, distinct from discriminative touch that identifies object properties. Affective touch is mediated primarily by C-tactile (CT) afferents in hairy skin and p…
- Anticipatory Grasp (Pregrasp Planning, Pre-grasp, Pre-shaping, Anticipatory Grasp Planning)
- Anticipatory grasp refers to the pre-shaping of the hand before contact with an object, based on expectations about the object's size, shape, and orientation. In sighted people this planning is driven…
- Audio-to-Haptics Translation (Audio-haptic translation, Audio-to-vibration conversion)
- A class of techniques that convert audio signals — either recordings of real-world interactions or AI-generated sounds — into vibrotactile patterns that can be rendered through actuators embedded in p…
- C-tactile Afferents (CT afferents, C-tactile fibres, CT fibres)
- Unmyelinated, slow-conducting nerve fibres found in hairy skin that respond selectively to gentle, slow stroking touch at velocities of approximately 1-10 cm/s. C-tactile afferents are strongly associ…
- Deep Pressure Therapy (DPT, Deep Pressure Stimulation, Deep Touch Pressure)
- A therapeutic approach that uses firm, distributed tactile pressure — such as from weighted blankets, compression garments, or inflatable vests — to reduce anxiety, stress, and physiological arousal. …
- Finger Assistive Device (FAD)
- A category of wearable assistive devices worn on a finger or fingertip that extend sensing or actuation to the primary locus of tactile perception. The term was introduced by Shilkrot et al. to classi…
- Fingertip Deflection
- A haptic guidance technique in which a wearable device gently pulls or tilts the fingertip in a chosen direction (abduction, adduction, flexion, or extension) to bias arm motion toward a target during…
- Haptic Design (Vibrotactile Design, Haptic Authoring)
- The practice of authoring haptic feedback - typically vibrations, forces, or temperature cues - so that it conveys intended meaning, emotion, or synchronicity with other media. Haptic design involves …
- Haptic Graph (Haptic Chart, Force-feedback Graph)
- A haptic graph is a non-visual rendering of a chart or graph — a bar chart, line graph, scatter plot, or mathematical function — that a blind or low-vision user explores by touch, typically through a …
- Haptic Icon (Hapticon)
- A short, structured vibrotactile or force pattern designed to carry meaning in the same way a graphical icon or audio earcon does, allowing users to recognize a category of information — an alert, mat…
- Haptic Rendering (Haptic display rendering)
- The process of computing and outputting touch-based signals — forces, vibrations, textures, or friction — so that a user can perceive virtual or remote objects through the sense of touch. Haptic rende…
- Kinesthetic (Kinaesthetic)
- Kinesthetic refers to the sense of body movement, limb position and muscular effort, arising from receptors in muscles, tendons and joints and closely related to proprioception. In accessibility and i…
- Kinesthetic Feedback (Kinesthetic Haptics, Force Feedback)
- A form of haptic feedback that engages the body’s sense of limb position, movement, and applied force — the kinesthetic sense mediated by receptors in muscles, tendons, and joints — rather than cutane…
- Mediated Social Touch (Remote Touch, Tele-touch, Haptic Telepresence)
- The use of haptic technology to simulate or communicate social touch gestures — such as stroking, squeezing, patting, or hugging — between people who are physically separated. Mediated social touch sy…
- Passive Haptic Feedback (Passive tactile feedback)
- Tactile information provided to a user by the inherent physical properties of a device or interface, without any active actuation. Examples include the raised bezel around a touch screen, the tactile …
- Phase-Based Motion Processing (Phase-Based Video Motion Processing, Phase-Based Motion Magnification)
- A family of computer vision techniques that decompose video frames into complex steerable pyramids and analyse changes in the temporal phase of each scale and orientation to recover motion, including …
- Skin Stretch (Tangential Skin Stretch)
- A haptic feedback technique that conveys directional or magnitude information by laterally stretching the skin at the fingertip, palm, or other contact point rather than by vibration or kinesthetic fo…
- Teleoperation (Remote Operation, Telerobotics)
- Teleoperation is the remote control of a physical system — a robot, manipulator, vehicle, or surgical instrument — by a human operator at a distance, typically using force-feedback haptic devices that…
- Texture Perception (Texture sense, Tactile texture perception)
- The perceptual capacity to detect and characterize surface properties — roughness, smoothness, bumpiness, graininess, stickiness, and directional patterns — through touch, vision, or cross-modal integ…
- Video-to-Haptics (Video to Haptics, V2H)
- A class of techniques that automatically generate haptic feedback (typically vibrotactile or force cues) from visual content in video, so that viewers feel sensations synchronised with what they see. …
