Relativ
Relativ is an open-source project for the development of custom virtual reality hardware, encompassing the mechanical design, electronics, and software interfaces required to build a headset from scratch. It provides the frameworks necessary for assembling devices using open-source electronics and firmware.
The project integrates custom hardware with SteamVR through driver-based configurations, mapping device identifiers and display viewports to ensure rendered images align with physical secondary displays. It employs a combination of microcontroller-based inertial measurement unit polling for head rotation and neural network-based pose estimation from camera feeds for 3D position tracking.
The system includes tools for sensor calibration to reduce drift by storing data directly on sensor memory, as well as processes for flashing processor-specific firmware to initialize hardware functionality.
