Why Trk-H?

Smart

The Entire Tracking Pipeline. On Board.

TRK-H handles sensor fusion, filtering, prediction, axis mapping and final 6-DOF output directly on the device. By moving the tracking workload off the host PC, TRK-H minimizes CPU overhead while preserving maximum processing headroom for the simulator.

Fast

Hardware speed, without the software bottleneck.

TRK-H performs the tracking on-device at high frequency. The lightweight TRK-H Runtime adds no heavy tracking or filtering layer—it simply delivers the already-computed tracking data to the simulator, preserving the device’s responsiveness all the way to the host.

Precise

Clean signal. Fine detail. No unnecessary filtering.

TRK-H’s multi-layer filtering suppresses sensor noise while preserving the fine movement data generated by the hardware. The result is a stable, high-resolution tracking signal delivered directly to the simulator.

"I built Trk-H because I wanted a head tracker that didn't make me compromise. After trying virtually every approach I could think of, this is the best head tracker I've ever experienced."

— H, Creator of Trk-H
