Haptic technology tactual perception. The sense of touch may be classified as passive and active, and the term "haptic" is often associated with active touch to communicate or recognize objects. Haptic technology has made it possible to investigate how the human sense of touch works by allowing the creation of controlled haptic virtual objects. The word "haptic", from the ("haptikos"), means "pertaining to the sense of touch" and comes from the Greek verb ("haptesthai)", meaning "to contact" or "to touch". According to Robert Lee this sensation is also referred to as 3D touch One of the earliest applications of haptic technology was
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
