Visuo-haptic mixed reality visually mixing real and virtual objects and haptic devices necessary to provide haptic stimuli to the user while interacting with the virtual objects. A VHMR setup allows the user to perceive visual and kinesthetic stimuli in a co-located manner, i.e., the user can see and touch virtual objects at the same spatial location. This setup overcomes the limits of the traditional one, i.e, display and haptic device, because the visuo-haptic co-location of the user's hand and a virtual tool improve the sensory integration of multimodal cues and makes the interaction more natural. But it also comes with technological challenges in
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
