Haptic perception by use of his body". Gibson and others further emphasized what Weber had realized in 1851: the close link between haptic perception and body movement, and that haptic perception is active exploration. The concept of haptic perception is related to the concept of extended physiological proprioception, according to which when a tool such as a stick is used, perceptual experience is transparently transferred to the end of the tool. Haptic perception relies on the forces experienced during touch. This research allows the creation of "virtual", illusory haptic shapes with different perceived qualities, which has clear application in haptic technology. People
Haptic technology by a fingertip, as a programmable function of the finger's motion. The TPaD Tablet Project uses an ultrasonic technology to modulate the slipperiness of a glass touchscreen, as if a user's finger is floating on a cushion of air. In February 2013, Apple Inc. was awarded the patent for a more accurate haptic feedback system that is suitable for multitouch surfaces. Apple's U.S. Patent for a "Method and apparatus for localization of haptic feedback" describes a system where at least two actuators are positioned beneath a multitouch input device to provide vibratory feedback when a user makes contact with the
