opentrack

opentrack is a free, open-source head-tracking program that manages and transmits pose information to games and simulators.

Why pair it with LookPilot?

  • Fallback for tricky titles – if a game’s built-in head tracking stutters or fails, routing motion through opentrack can restore smoothness.
  • Broader compatibility – for games without an official head-tracking API, opentrack can still drive them via outputs such as Virtual Joystick (vJoy), SimConnect, OpenXR, or raw UDP—options not exposed directly by LookPilot.
  • Extra filters – opentrack ships several alternative filtering algorithms (Accela, Kalman, EWMA, etc.) that some users prefer over LookPilot’s built-in choices.
  • Open ecosystem – a large community and an extensive plugin library make troubleshooting and experimentation easier.

How to use opentrack (quick version)

  • In opentrack, choose an Output your game supports (e.g. Freetrack, Virtual Joystick, or SimConnect).
  • Click Start to begin tracking.
  • Pick a filter under Filter if you want smoothing beyond the default.

For a detailed walkthrough with screenshots, see the official Quick-Start Guide. Many video tutorials are also available on YouTube.

Recommendations for LookPilot + opentrack

  • Adjust mapping curves in only one app (either opentrack or LookPilot) and leave the other set to Identity.
  • To use LookPilot’s filtering (smoothing or deadzone), set Filter to None in opentrack.
  • To rely on opentrack’s filters instead, set Deadzone and Smoothness to 0 in LookPilot (under Head-tracking settings and Eye-tracking settings).
