FaceTrackNoIR is a headtracking program that uses the SeeingMachines FaceAPI. Movements of the head are registered by a simple web cam; no additional hardware (eg. markers) are required. FlightGear support is built in, so you can look around in the FlightGear world by rotating your head.

Run with FlightGear

  1. Download and install FaceTrackNoIR, as prescribed in the README contained in the zip-file or alternatively in the installation manual.
  2. You will have to move 2 files to the FlightGear root. Both files are called "headtracker.xml", but their content is different! One file goes to $FG ROOT/Nasal and the other goes to $FG ROOT/Protocol. The files can be found in FaceTrackNoIR's file section.
  3. Make sure you closed any webcam software that might be running. This is really important, failing to do so will probably stop FaceTrackNoIR from working.
  4. Start FaceTrackNoIR.
    • Select "Game Protocol: FlightGear" and click the "Start" button under "Tracker Source". You might have to restart the FaceTrackNoIR once, after clicking "Start".
    • A small window with your webcam's view should show up in the leftbottom corner. Make sure your head is well within the view and eyes, nose and cheeck are outlined by a yellow line. When you move/rotate your head, the lines should follow your movements.
  5. You can run FTNoIR through two ways:
    • Run FlightGear, with the following (extra) commands:
      --generic=socket,in,25,localhost,5550,udp,headtracker
      --generic=socket,out,10,localhost,5551,udp,headtracker
      --prop:browser=/sim/headtracker
      --config=$FG ROOT/Nasal/headtracker.xml
    • Set the commands showed above via FGRun. All of them can be set via Advanced on the last page of the launcher.
  6. While running FlightGear, open the FaceTrackNoIR dialog and edit the sensitivity bars, so that your head movements correspond well with FlightGear's view movements. Ticking the "invert" boxes might be neccesary if your movements are mirrored.

Troubleshooting

I get a "missing ... .dll" error

Download the faceAPI demo to install the neccessary .dlls.
