What are the tech specs of the head tracking camera?

The camera tracks the FOVE 0 headset position at 100Hz, then is augmented with acceleration and rotation values from the internal IMU at 1000Hz. This is done via infrared lights on the exterior of the headset. The outer plastic is transparent in this band of IR.

The head tracking camera comes with the FOVE0 headset, but is not required, in which case only 3 DOF are available instead of 6. When the head tracking camera is not in use, the USB2.0 cable from the FOVE0, which lights the headset external IR LEDs, is also not required to be plugged in (thus reducing one cable from the camera, and one from the headset).

The camera's telemetry data is available via the SDK (and thus the Unity plugin, etc) via ResearchHeadset::getImage, and the computed coordinates is available in the headset pose. Both sets of information (image and compoted pose) can be viewed anytime, in realtime, with the FOVE Debug Tool, included as part of FOVE's standard software distribution.
