TRACKING SYSTEMS
Inside-out tracking
● The camera is placed on the tracked device and looks
outward to determine its location in the environment.
● Headsets that use this tech have multiple cameras facing
different directions to get views of its entire surroundings.
The Lighthouse system used by the HTC Vive is an
example of active markers.
● Each external Lighthouse module contains IR LEDs as
well as a laser array that sweeps in horizontal and
vertical directions, and sensors on the headset and
controllers can detect these sweeps and use the timings
to determine position.
