## What it is
SlimeVR is an open-source full-body tracking system for VR consisting of ESP32/ESP8266 tracker firmware supporting various IMU sensors and a companion server that fuses tracker data into body poses for SteamVR. It enables affordable, camera-free and base-station-free body tracking using Wi-Fi-connected IMU trackers.

## Use cases
- full-body tracking in VRChat without base stations
- build DIY IMU body trackers with ESP32 and BNO085
- motion capture recording to BVH for Blender
- VTubing tracking via VMC without a headset
- replace expensive Vive trackers with affordable sensors
- chest or waist tracking for standalone VR games

## When to choose
- you want affordable camera-free full-body tracking for SteamVR games
- you enjoy DIY hardware and want customizable tracker builds
- you need motion capture data without occlusion issues

## When to avoid
- you need sub-millimeter positional accuracy like lighthouse base stations
- you want a plug-and-play commercial solution with warranty
- you cannot tolerate occasional IMU yaw drift and calibration
