FBT VR Accessory

December 2, 2025

The FluxPose system is a new virtual reality (VR) accessory currently funding on Kickstarter. It is designed to provide Full Body Tracking (FBT), which allows your real-world body movements (like kicking your legs, dancing, or lying down) to be mirrored instantly by your avatar in games like VRChat. Current tracking systems usually force you to choose between accuracy (using external cameras) or convenience (using motion sensors that drift or lose accuracy over time). FluxPose uses magnetic field technology to try and offer both: high precision without needing to mount cameras on your walls.

To understand why FluxPose is unique, you have to understand the biggest headache in VR tracking: Occlusion. Most high-end systems (like the HTC Vive) use lasers or cameras mounted in the corners of your room. If you hide a tracker under a blanket, or if you cross your arms and block the camera's view of your chest, the system loses track of you. This is called occlusion. FluxPose uses magnetism, not light. Just as a compass works even if it's inside a backpack, FluxPose trackers can see the base station through blankets, clothes, pillows, and your own body. This makes it occlusion-free.

Instead of placing cameras around your room, FluxPose centers the system on you. You wear a device called a Beacon on your belt (roughly the size of a deck of cards). This device generates a safe, invisible magnetic field bubble around you, with a radius of about 1.5 to 2 meters. You strap small, lightweight sensors (about the size of a coin and weighing only 15 grams) to your feet, knees, elbows, or chest. These sensors measure the strength and direction of the magnetic field generated by the Beacon to figure out exactly where they are in 3D space. Because the field moves with you, you have a portable tracking bubble. You can turn around, curl up under a duvet, or have someone stand in front of you, and the tracking remains unbreakable.

The FluxPose offers 6 Degrees of Freedom (6DOF), which means the system knows exactly where you are and how you are rotated. The trackers also claim a 24-hour battery life, which is significantly longer than most industry standards. Additionally, these units have vibration motors inside, meaning developers could program them to vibrate when your avatar gets touched or bumps into something.
