The Feelreal VR Mask fits somewhat awkwardly over the lower half of your face and optionally mounts to the bottom of a VR headset such as the Oculus Rift. The device includes an "odor generator" that takes seven removable "smell cartridges," which vaporize a mixture of perfumes to create an appropriate scent for the game you're playing or the movie you're watching.
The basic set of smells includes; jungle, flowers, ocean, burning rubber, fire, gunpowder, and aphrodisiacs. But Feelreal will be allowing orders of a number of other predesigned smells as well as custom-made smells for an additional $300 and can describe the smell in detail.
The Mask also includes micro-coolers and heaters that generate a sensation of heat or wind and a couple of haptic motors for force feedback as well as an ultrasonic ionizing system that makes it feel like tiny water droplets are striking your cheeks.
