  • We can't help but experience a little déjà vu as we unmask our latest subject.

  • Pulling back the outer shell on the Vive reveals a number of sensors—32 in total, according to HTC.

  • These photodiodes take in IR light from the two Lighthouse base stations as they flash and sweep light across the room. This enables a connected PC to calculate the headset's position and orientation in space as a function of the time between receiving the flash and the following IR laser sweep.

  • This method is the exact opposite of the head-tracking technique found in the Oculus Rift. In the Rift, the desk-mounted camera tracked the IR emitters in the headset, whereas in the Vive, the headset sees light from the mounted IR emitters without actually "tracking" its location.
