Dispersive Signal Touch Technology
... Dispersion is the phenomenon that the velocity of a bending wave propagating through solid material is dependent upon that wave’s frequency. An impulse caused by a touch contact generates a number of bending waves within the substrate, all at different frequencies. Because of “dispersion”, these ben ...

Haptic technology
Haptic or kinesthetic communication recreates the sense of touch by applying forces, vibrations, or motions to the user. This mechanical stimulation can be used to assist in the creation of virtual objects in a computer simulation, to control such virtual objects, and to enhance the remote control of machines and devices (telerobotics). Haptic devices may incorporate tactile sensors that measure forces exerted by the user on the interface.Most researchers distinguish three sensory systems related to sense of touch in humans: cutaneous, kinesthetic and haptic.All perceptions mediated by cutaneous and/or kinesthetic sensibility are referred to as tactual perception. The sense of touch may be classified as passive and active, and the term “haptic” is often associated with active touch to communicate or recognize objects.Haptic technology has made it possible to investigate how the human sense of touch works by allowing the creation of carefully controlled haptic virtual objects.The word haptic, from the Greek: ἁπτικός (haptikos), means ""pertaining to the sense of touch"" and comes from the Greek verb ἅπτεσθαι haptesthai, meaning ""to contact"" or ""to touch"".
