Haptic technology Air vortex rings are donut-shaped air pockets that are concentrated gusts of air. Focused air vortices can have the force to blow out a candle or disturb papers from a few yards away. Two specific companies have done research using air vortices as a source for non-contact haptic feedback. In 2013, Disney worked on a technology they called AIREAL. This system delivered non-contact haptic feedback through the use of air vortex rings. According to Disney, AIREAL helps users experience textures and "touch" virtual 3D objects in free space. This is all without the need for a glove or any other
Haptic technology world via a tool or stylus, giving a form of interaction that is computationally realistic on today's hardware. Systems are being developed to use haptic interfaces for 3D modeling and design that are intended to give artists a virtual experience of real interactive modeling. Researchers from the University of Tokyo have developed 3D holograms that can be "touched" through haptic feedback using "acoustic radiation" to create a pressure sensation on a user's hands (see future section). The researchers, led by Hiroyuki Shinoda, had the technology on display at SIGGRAPH 2009 in New Orleans. Several companies are making full-body or torso
