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 technology a Boston University paper published in "The Lancet", "Noise-based devices, such as randomly vibrating insoles, could also ameliorate age-related impairments in balance control." If effective, affordable haptic insoles were available, perhaps many injuries from falls in old age or due to illness-related balance-impairment could be avoided. In February 2013, an inventor in the United States built a "spider-sense" bodysuit, equipped with ultrasonic sensors and haptic feedback systems, which alerts the wearer of incoming threats; allowing them to respond to attackers even when blindfolded. During a laparoscopic surgery the video camera becomes a surgeon's eyes, since the surgeon uses the image
