  Haptic technology, or haptics, is a tactile feedback technology which takes
advantage of a user's sense of touch by applying forces, vibrations, and/or
motions upon the user. This mechanical stimulation may be used to assist in the
creation of virtual objects (objects existing only in a computer simulation),
for control of such virtual objects, and for the enhancement of the remote
control of machines and devices. It has been described as for the sense of
touch what computer graphics does for vision. Although haptic devices are
capable of measuring bulk or reactive forces that are applied by the user, it
should not be confused with touch or tactile sensors that measure the pressure
or force exerted by the user to the interface.
