A Review Of The Free Head Tracking Aruco Marker, For Sim Racing In F1 2020, And Assetto Corsa

[NOTJustANomad]

I've been using the aruco marker for flight sims (IL-2 Sturmovik, DCS, Elite Dangerous etc) for a few years. It is by far the easiest to set up cheap option for anyone who wants to try out headtracking. As long as the light condition is half-decent in your room (I even fly at night with only a lamp on on the opposite side of my room), the aruco marker COULD provide precision tracking as good as TrackIR. I say COULD, because the result is hugely dependent on two things: the camera position and OpenTrack settings - to be more precise, the calibration and the curve tuning.

I understand this video is not a "how-to tutorial" but a review. I really enjoyed watching it - it is thorough and informative. But I think it is worth mentioning a few key points so that new users can nail down the issues they often have:

1. Make sure the camera placement is good. By that I mean, the camera should be close enough to your face (something between an arms length to 1 meter should do), and it shouldn't be too low in relation to the tracker height. My Monitor is set at my eyes' height as the center line of my monitor is exactly where my eyes are. The camera is placed on top of the monitor - which means it is at about 80-90 cm away from my face, some 10-15 cm higher than my forehead.

2. IMPORTANT! Make sure the marker itself is at an angle in relation to the camera. In other words, the surface of the marker should NOT be anywhere close to perpendicular to the camera's view at ANY moment during use. I bend my marker a bit backwards (the marker's surface is facing the ceiling a bit) by some 20°-25° and it works really well for my curve tuning.

3. Make sure to use the calibration feature in the OpenTrack software to set the center of rotation. Click on the wrench icon next to the Aruco option, set the XYZ axis so that when you turn on the tracker, a pink dot should be around the center of your head - aka. inside your head. The goal is to achieve the neutral movement. When you only do yaw, the octopus should also only do yaw (doesn't have to be very precise, but make sure it doesn't move a lot on the X and Z axis). And when you do pitch, the octopus should only do pitch without much movement on the Y and Z axis.

4. Curve tuning: the simple quick start rule of thumb is to set the yaw curve to linear and when your face is pointing to the edge of your screen, OpenTrack should translate that into about a 160-180° in-game movement for flight sims, or the maximum needed yaw angle for your desired game. From there, set up the other rotational axis until you are comfortable. Then do the spacial axis so you don't have to move too much to achieve the needed in-game movement (up, down, sideways).

Turning exposure Down on the camera increased fps to max the cam can handle. Can adjust settings so you don’t have to look as far. After a couple of days and adjusting settings. Have to have the lighting just right too. It works better than I was anticipating.

I think you need to work with the sensitivity settings in your tracking software. You should be able to set it so that just turning your head slightly gives a large yaw.

You can use much smaller marker, i use 9X9 cm, works amazing.

Such a big head movement. You should really update this video. Any big head novement and you will likely lose tracking.

You don’t need an expensive webcam, just high FPS and fov so image quality doesn’t matter a lot. The ps3 eye can be used on the pc with a download of a program and it’s only £10 on eBay. It was designed for motion tracking. And you can use a much much smaller marker which is more comfortable (I used blue tack on the top of my headset and don’t know it’s there). Also for sim racing if you disable everything except ‘yaw’ it would work better. There are 6 tracked things x, y, pitch, yaw etc and while I might need that for flight sims (to look up and down at screens etc) for racing probably just need to look left and right (yaw) . Nice vid mate 👍 Best wishes from the UK

how to enable in asseto? i cant find the setting

Hey man, i havnt tried yet because no webcam, but i know 3 things help u, aruco placement to be not dead center, tilt it upwards to point camera off angle, 2 play with sizes, 3 dont expect no jitter with a webcam, if u want no jitter, try a video camera, live feed to pc, now use aruco, much better. I use for DCS flying mostly so no sudden movements needed Hope it helps.

[Momodka]

can you show how setup CM to assetto for tracking ?

[boylikenik]

hey dude what do you use to strap the Armco thing to your head? Thanks for answering
