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.
