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 flight simulators for pilot training. It is very critical to exert proper force magnitude to the user. It requires considering human force sensitivity. Haptic feedback is commonly used in arcade games, especially racing video games. In 1976, Sega's motorbike game "Moto-Cross", also known as "Fonz", was the first game to use haptic feedback which caused the handlebars to vibrate during a collision with another vehicle. Tatsumi's "TX-1" introduced force feedback to car driving games in 1983. The game "Earthshaker!" was the first pinball machine with haptic feedback in 1989. Simple haptic devices are common in the form of game controllers,
