haptic technology Haptic technology (also kinaesthetic communication or 3D touch) is technology that can create an experience of touch by applying forces, vibrations, or motions to the user. These technologies can be used to create virtual objects in a computer ...

to provide haptic perception of simulated, virtual objects within an augmented-reality (that is, within a mostly-realistic) setting, stereohapty, which, when applied as a field of study, is known as stereohaptics or stereotactics, stereotaxy aims to provide an illusion of three-dimensional depth to the sense of touch by the human body. This resembles how
