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 type of physical haptic feedback. Disney took on this research because they believed that technology is advancing towards more virtual or augmented reality applications. According to Disney, the missing piece in this emerging computer-augmented world is the absence of physical feeling of virtual objects. Disney's main intention for this research was to encourage other research regarding new applications of non-contact haptic feedback. In 2013, Microsoft explored the same area as Disney. They used air vortex rings in order to try and provide haptic feedback for an at-a-distance interaction. Microsoft mostly focused on the study of vortex formation theory and parameters
