Haptic technology 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 controlled haptic virtual objects. The word "haptic", from the ("haptikos"), means "pertaining to the sense of touch" and comes from the Greek verb ("haptesthai)", meaning "to contact" or "to touch". According to Robert Lee this sensation is also referred to as 3D touch One of the earliest applications of haptic technology was
Haptic memory hand. Babies were able to encode haptically some characteristics or features of objects without visual control with their left hand as well as with their right hand. In the experiment, haptic habitutation was formed through an occurred stimuli and at the end, it has seen that even though stimuli was not present, infants still carry on their stimuli habit. It was also shown that infantile haptic memory is robust in that it is somewhat resistant to delays (especially in males). These findings support earlier results by Catherwood, which stated that 8-month-old infants were able to recognize a familiar shape after
