(via & more GIZMODD http://gizmodo.com/whoa-disney-made-video-game-rumble-feedback-for-kinect-843248736)Virtual reality only immerses two of your senses: sight and hearing. Not that we're dying for smell and taste in video games (bleh! Imagine first person shooters), but tactile feedback makes things feel a lot more real. Disney Research's Aireal does this by blowing puffs of air in your face, and it's not nearly as crazy as it sounds.
Inside the camera-sized device, five subwoofer-like actuators blast a very low frequency through a movement-following nozzle, creating a low-pressure ring of air traveling toward you. When the ring hits your skin, it collapses, and you feel a small, sharp puff. The frequency of the pulses can be varied to create different textures and sensations, and with a firing range of about six feet and 75 degrees of articulation, it's perfectly dialed in for Kinect-style close-range interaction.
