Show HN: Open modular tracking stack for VR/MR headsets (eye, SLAM, FBT, BCI) [video] (youtube.com)

My team and I have been building a VR headset + MR glasses platform for the past few years, and one of the biggest challenges has been tracking.

A few months ago we started developing a modular tracking stack called Shinra Meisin, focused on:

- Low-latency edge processing - Privacy-first architecture - Modularity and hardware flexibility - XR-focused tracking pipelines

The system currently includes:

- Eye tracking - Mouth tracking - SLAM - Inside-out full body tracking - Experimental BCI integration

Today we’re showing our current eye tracking progress and plan on showing off SLAM within the next two(ish) days.

Real time landmark accuracy is 80-85% and gaze is 1.0-2.0° (Which will increase exponentially once I get John (My dev) a better GPU and help train a dataset off of 40ish people
