PHANTOM(also: PHANTOM Omni, PHANTOM Desktop, SensAble PHANTOM)

A family of force-feedback haptic devices originally developed by SensAble Technologies (now part of 3D Systems). PHANTOM devices use a pen-like stylus that users grasp while motors apply forces to create the sensation of touching virtual objects or being guided along…

Pantograph(also: Haptic Pantograph)

A haptic input device that allows users to explore a two-dimensional surface by physically moving a stylus or finger pad across an exploration area, while receiving tactile feedback from an attached tactile display. In accessibility applications, the pantograph enables people…

Peltier Module(also: Peltier Device, Thermoelectric Module, TEC Module)

A Peltier module is a thermoelectric device that creates a temperature difference when electrical current is applied, with one side heating up and the other cooling down. In assistive technology, flexible Peltier modules are used to provide thermotactile feedback — controlled…

Phantom Sensation(also: Phantom Vibration, Vibrotactile Illusion)

A phantom sensation is a perceptual illusion in which two vibrotactile actuators stimulating the skin simultaneously create the feeling of a single vibration at a point between them. By varying the amplitude and frequency of each actuator, the perceived location of the phantom…

Pin Array Display(also: Pin Matrix Display, Tactile Pin Display)

A type of tactile display technology that uses an array of individually controllable pins that can be raised or lowered to create tactile patterns, textures, and graphics. Pin array displays are used in 2D tactile displays to present graphical information such as diagrams,…

Pseudo-Attraction Force

A haptic illusion technique that creates the sensation of being pulled or pushed in a specific direction by exploiting the nonlinear relationship between physical and perceived acceleration. The technique uses asymmetric oscillation: a strong, brief acceleration in the intended…
