SlimeVR Full-Body Tracker: An affordable, comfortable, wireless, 360° virtual reality full-body tracking solution

SlimeVR is a set of open hardware sensors and open source software that facilitates full-body tracking (FBT) in virtual reality. Without the need for a base station, SlimeVR makes wireless VR FBT affordable and comfortable. SlimeVR FBT provides simple, effective body and limb tracking in VR games and other applications. It utilizes high-quality inertial measurement unit (IMU) sensors and a Wi-Fi connection to a PC instead of wires, cameras or base stations to make full-body tracking comfortable and affordable. Take the lower-body suit, for example, where five trackers—one on each thigh, one on each ankle, and one on the waist—are enough to get the job done. Each tracker monitors its own rotation in space, and the SlimeVR software uses your scale and headset position to calculate joint angles and estimate limb position. In more technical terms, SlimeVR relies on absolute orientation sensors, a configurable skeleton model, and forward kinematics. The result is like having virtual Vive trackers installed at strategic locations on your body.
