A new add-on for the Oculus Rift virtual reality headset allows the person wearing it to experience smell, heat, cold, and more. A VR research and development company called Feelreal demonstrated the Bluetooth-powered mask recently at the Game Developers Conference in San Francisco.

The Feelreal mask uses heaters, coolers, misters, a vibration engine, a microphone, and even a "removable cartridge with seven unique smells." These smells are: Ocean, Jungle, Fire, Grass, Powder, Flowers, and Metal.
