Question: what are the oculus rift sensors for?
Answer: With a clear line of sight, Oculus Sensor tracks constellations of IR LEDs to translate your movements in VR. Its stand is ideal for most setups, and its standard 1/4-20 mount works with most tripods. Requires Rift, sold separately. When used as a third sensor, it requires an additional port – at least USB 2.0.
