C-tactile Afferents(also: 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 associated with affective and social touch, activating neural pathways linked to…

Cane Simulation(also: 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 simulation, the user's finger or hand position is mapped to a virtual cane that…

Collision Detection(also: Contact Detection, Intersection Testing)

In virtual reality and haptic systems, collision detection is the computational process of determining when virtual objects come into contact with each other or with a user's virtual representation (such as a virtual hand or cane). When a collision is detected, the system can…

Core Haptics

Apple's iOS framework for designing and playing custom vibrotactile patterns on iPhone using the Taptic Engine. Core Haptics lets developers synthesize transient 'taps' and continuous vibrations, vary intensity and sharpness over time, and synchronize haptics with audio using…

Cutaneous Perception(also: Cutaneous Sense, Cutaneous Feedback, Tactile Perception)

The sensory experience derived from receptors beneath the surface of the skin that respond to temperature, pain, and pressure. In the context of assistive technology, cutaneous perception enables users to detect surface textures, raised patterns, and embossed details through…
