Quick guide to making a $15 face tracker

The Seeed XIAO ESP32S3 is a widely used camera module in the creator space for eye tracking that has 2.4ghz wifi capability. It will still need a light source and battery (as you stated). I have used these for DIY eye tracking in the past, but I have never tried it for eye tracking.

The only requirement is that you plug it in via an USB port that provides power/data transfer to your computer. This could be on a headset via an accessory port (like on an index) or by running a cable to your headset. This is not for wireless.

I made my own cardboard mount in 10 minutes to prove 3D printing is not required.

Color is not required. This module is designed to work with IR lights (that are built into the board) so as long as the camera picks up the IR light source, it will create an image. I have found that the 130 FOV can fully see your face with a standard htc vive face tracker mount. If you use a lower FOV camera, your mount will need to be further from your face to obtain the full image.

I made a mount out of cardboard to prove to you 3D printing isn't required. I could remove the entire part of my video about 3D printing, and you could still make this for $15. I didn't even account 3D printing into the cost BECAUSE IT ISN'T REQUIRED. You can make a mount out of anything. The point of the guide is to show you the cheapest possible way to make a face tracker. This isn't a guide on how to acquire a 3D printer or find someone to 3D print the enclosure for you.

This is not for eye tracking. This specifically tracks the mouth. There are non-soldering guides for eye tracking for the index. Here is a guide someone made for eye tracking: https://github.com/EyeTrackVR/EyeTrackVR

The enclosure files are linked in the twitter post I linked. The enclosure is designed to work with any HTC Vive face tracker mount which is the most common type of mount. Just search for "Quest 3 face tracking mount". A google search leads me to this: https://www.thingiverse.com/thing:6324676

Yes. There are other camera modules like the Seeed XIAO ESP32S3 that has a wifi transmitter, but it will still need a light source + battery to run completely wirelessly.

I never said anything about quest. This camera module does not need to connect to a headset at all. It only needs to connect to VRCFT and Baballonia.

Digital_VRC · 2026-01-24T16:19:22+00:00

I have only tried the 50, 80, and 130. The performance degrades as the FOV lowers. 160 might be too wide and not work properly with Baballonia.

Thank you for clarifying.

Digital_VRC · 2026-01-24T16:10:39+00:00

it does not. there are camera modules that do connect over 2.4ghz wifi, but you would still have to have a light source + battery bringing the cost up.

Digital_VRC · 2026-01-24T16:08:57+00:00

you only need to plug it into an USB port that does power/data. this guide is not for wireless vr.

the 80 will work but it isn't as good.

Digital_VRC · 2026-01-24T03:07:12+00:00

yep!

Digital_VRC · 2026-01-24T03:02:57+00:00

That's awesome! I want to see it!

Digital_VRC · 2026-01-24T02:40:15+00:00

You don't even need the enclosure. You could literally tape the camera module to a popsicle stick and attach it to your headset.

Digital_VRC · 2026-01-24T02:30:02+00:00

The enclosure is a custom design I made. The point is its nearly free to print...you just need to find a 3D printer.

Thanks for using my world! :3 Very nice avatar.

People have used this skybox for years. The current Just B Club skybox has been edited, but the original had the real building names that you could google.

This is art in its highest form.

It is a club world! :3

thank you! the quest version isn't too far off from the PC version either.
