It's achieved by placing electrodes behind each ear, on the forehead and at the base of the skull. From there, electrical impulses are sent to simulate the type of vestibular (inner ear) responses one would have for rotating left or right. Mayo Clinic has licensed it to vMocion, an LA-based entertainment outfit, however there haven't been any other takers so far from the likes of HTC, Sony or Oculus.

But implementing the tech into any of those three right now is pretty much impossible now that PlayStation VR pre-orders are open, the fact that the Rift's first consumer headset shipped this week and the Vive releases next month.
