Therefore, given that virtual reality (VR) headsets are meant to replicate real-world experiences, shouldn't they provide odors along with sights and sounds? That's the idea behind the smelly new Vaqso VR system.
The main Vaqso unit is linked to a third-party VR headset via micro USB or Bluetooth, and it extends around the user's face in a semi-circle. It contains five replaceable cartridges, each of which is loaded with one of 15 currently-available scented oils. When triggered by code within the VR game that the wearer is playing, the device selectively releases odors from the cartridges, those odors being relevant to what's happening in the game.
