An expert look inside the HTC Vive's positional tracking system

“This means that at OpenVR’s internal interface, worst-case latency for head tracking data is about 1ms, and worst-case latency for controller tracking data is about 2.7ms, assuming that wire(-less) transmission and pose calculation add negligible latency,” Kreylos notes, adding that the tracking data is delivered to applications at a slower rate via vrserver.

I decided to cobble together a small testing utility to get a feel for OpenVR’s internal driver interface, and for the Lighthouse tracking system’s overall tracking quality.”
