Over 2 Million Euros: Magnetic Full-Body Tracking Becomes a Crowdfunding Hit

FluxPose introduces a system for magnetic full-body tracking in VR that could represent a compact alternative to Valve's Lighthouse tracking.

The small tracking modules from FluxPose are intended to transfer full-body movements into virtual reality.

The startup FluxPose is currently raising money via Kickstarter for a new tracking system and is proving astonishingly successful. Supporters have already raised more than 2 million euros, far exceeding the original goal of 200,000 euros. Instead of external cameras or base stations, FluxPose relies on magnetic fields and inertial sensors to precisely capture body movements in virtual reality.

The tracking zone always with you

To do this, users strap a portable transmitter around their hips, which generates a local magnetic field that the trackers use for spatial orientation. The tracking zone therefore always moves with the body, which rules out accidentally leaving it. At the same time, the tracking is intended to remain stable, as the distance between the transmitter and receiver never increases to a critical level.

According to the manufacturer, the system does not require calibration. A tracker on the VR headset is used for automatic synchronization with the VR space. Up to ten trackers can be connected via a dock, which also functions as a charger and radio receiver.

Compact, Stable, and Open

The trackers are compact (approx. 3.7 cm × 3.7 cm × 1.08 cm), weigh only 15 grams, and according to the manufacturer, last up to 24 hours. The main module is said to last between six and 24 hours depending on the mode. Drifting, i.e., the gradual divergence of tracked position and real movement due to multiple small measurement errors, is not expected to occur. Thick clothing or blankets are also not supposed to interfere with the signal.

FluxPose is likely to be of particular interest to VR fans looking for precise full-body tracking – for example, for VRChat or dance and rhythm games. Developers can also use the system: the trackers are openly documented, can be loaded with their own firmware, and integrated into their own projects via an API. FluxPose intends to provide adapters for gloves, controllers, or other accessories.

Most current VR headsets are supported, such as Meta Quest 3, Pico 4 Ultra, Samsung Galaxy XR, Bigscreen Beyond 2, or the upcoming Steam Frame from Valve. Depending on the kit, three ("Lite"), five ("Core"), or eight trackers ("Pro") are included. Prices start at 339 euros plus taxes. Those who own a 3D printer can produce straps and mounts themselves. FluxPose provides the corresponding templates.

The Kickstarter campaign runs until the end of January 2026. First deliveries are planned for autumn 2026. According to FluxPose, over 300 units have already been built and tested by beta testers. However, as with any crowdfunding campaign, a residual risk remains.
