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 opposed to verbal or semantic aspects. Haptic abilities develop in stages in infants: The last two decades have allowed researchers to study the sensory system of infants which gives an insight to the initial stages of thinking, deciding and reasoning in a human brain. Evidence of haptic memory was discovered in infants as young as two months by Myriam Lhote and Arlette Streti, who demonstrated that haptic habituation occurs asymmetrically between the hands of infants, and that differences in haptic memory exist between sexes. For instance, in 2-month-old infants, haptic habituation was found in both the right and the left
