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 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
