Relativty: An open-source VR headset for $200

From the GitHub this is only capable of 3DoF tracking, which puts it in the same category as the defunct Oculus Go headset, or Google Cardboard. 6DoF is really the bare minimum to qualify as proper VR nowadays.

For the uninitiated 3DoF means the headset only tracks the rotation of your head, not your heads absolute position as you move around, while 6DoF tracking does both. 6DoF is also much harder to implement.

Never understood why my GCardboard couldn’t do that, my phone sure has a bunch of accelerometers and giros. Sure higher and other techs can track better but isn’t it enough for a basic sense of mouvement? For most of the applications I won’t more than a few meter anyway.

Probably some have tried and I’ll be curious to know what prevent it.

Dead reckoning using MEMS IMUs accumulates error way too fast.
