Thanks to the dedicated beta-testing team :)
FluxPose generates its own magnetic fields around the beacon, creating a 3.5m diameter "wearable" tracking sphere that can support an unlimited number of trackers. The system mixes the occlusion-free EMF readings with ultra-low-latency, high-precision IMU data, combining the advantages of both worlds for a great tracking experience.
Background static fields, like the ones from magnets or the Earth, are automatically ignored.
FluxPose also introduces several new breakthroughs in magnetic tracking, delivering equal or better performance than other EMF solutions while consuming far less power. For context, the Pico Neo 2’s EMF tracked controllers used a battery 3x larger than FluxPose's beacon, yet managed only 1/5th the runtime.
The technology
EMF tracking
Every FluxPose tracker undergoes a rigorous, multi-step calibration process to guarantee great accuracy under real-world conditions.
Each IMU is profiled for bias, scale factors, and cross-axis alignment while being cycled through the full operating temperature window (15º-50º). The resulting correction is stored on-board and applied in real time. As a result, you can expect a total zero offset of <1mg and <0.01º/s in the accelerometer and gyroscope, respectively. Gyro sensitivity is also calibrated within 0.015% of its real value. Some of these values are further calibrated dynamically during runtime.
The EMF data is calibrated inside a spherical test volume that covers a comprehensive set the positions and orientations the system will see during runtime. A dense set of poses is sampled to produce compensation matrices that drive both positional and rotational error to negligible levels. (See the System Datasheet in the Downloads page for more figures)
The calibration
Shit in = Shit out
FluxPose uses a fully custom protocol built on top of Nordic's 2.4GHz proprietary radio. It is designed from the ground up to be as low-latency and high-bandwidth as possible while requiring the least amount of RF space (channels) and therefore, dongles. By tightly packing data frames and optimizing airtime scheduling, the link achieves both high-frequency and low-latency updates while occupying only a fraction of the spectrum.
It works so well that in a typical scenario, a single RF channel (one dongle or docking station) can handle up to 8-10 devices streaming at 150 Hz each without introducing perceptible delay. This efficiency is key to having great performance in environments with high radio congestion. You can always use more dongles/docks at the same time, and the system will split the traffic among them.
The comms
Optimized RF
If you love DIY stuff or are just curious about how things work (like we are), FluxPose is designed to be easy to tinker with.
All FluxPose devices have open bootloaders; if you bought the hardware, it is yours to do whatever you want (under your own responsibility).
Do you want to integrate FluxPose into something else? Then check the downloads page for integration manuals, drawings, and 3D models.
You got a new headset or broke one of your straps? You can choose to just 3D print them yourself instead of relying on us.
Open ecosystem
Be nice
FluxPose creates magnetic fields around the beacon that are used to position the trackers with no occlusion. Static fields from magnets or the Earth are automatically ignored and have no effect. By combining them with very accurate IMU data, the system knows where a tracker is located.
FluxPose uses several unique approaches to magnetic tracking that have never been seen before. We get the same or better tracking quality than other EFM solutions while using way less power.
For example, the Pico Neo 2, which also used an EMF tracking system, had a battery 3x larger than our beacon and lasted 5x less!
Each FluxPose tracker goes through a long calibration process, to ensure the best performance.
Each IMU is calibrated for bias and sensitivity across the 15ºC - 50ºC temperature range, among other things.
The EMF data gets calibrated so to minimize the error in all possible positions and rotations in a 1m radius sphere.

It works so well, that in most cases, only 1 RF channel (dongle/dock) should be enough for 8-10 devices running at 150Hz with no significant latency hit!

FluxPose under the hood
There are so many things that make FluxPose tick, and so little that we can fit here.
If you are still curious after reading this, head over to the FAQ and Downloads page to learn more :)
-
Do I need to buy a dongle?No, the charging dock also acts as a wireless dongle when connected with a USB cable to the PC. Each dock/dongle is capable of handling up to 10 devices. If you want to add more devices, reduce latency in congested environments or prefer not to connect the dock to the PC, you can buy one or more dongles. You can use as many docks/dongles as you want at the same time, the system will automatically split the wireless traffic amongst them.
-
What headsets can I use FluxPose with?For a full 6DOF experience you need to attach a tracker to the HMD. We supply adapters for the most common HMDs, you can check the store for available adapters or the downloads page for 3D models that you can print yourself for free. Additionally, you can create your own adapter or use one created by the community for your headset. For more information on community adapters, you can check our Discord server. If you want to build your own adapters you can find resources and guides to aid you in the process in the downloads page.
-
Can I use FluxPose with a standalone headset like the Quest 2/3?After the beta period, OSC trackers will be supported.
-
What wireless communication system does FluxPose use?FluxPose uses a custom proprietary 2.4GHz protocol that aims to provide the lowest possible latency while supporting up to 10 devices per Dock/Dongle. So you don't need to worry about your WiFi router/connection or anything like that. Each Dock/Dongle, while supporting up to 10 devices simultaneously, uses only a single 1MHz 2.4GHz channel. If you want increased bandwidth (for higher refresh rates for example), even lower latency or more resilient communication in tough environments, you can always connect more receivers (Docks/Dongles) to your PC. The system will automatically split the wireless traffic among all the receivers.
-
How long does the Battery last? What are the power modes?Up to 24 hours. There are three different power modes available: Power saving, Balanced and Performance. They significantly impact the battery life of the beacon. Depending on the tracking volume/performance you want, you can select different power modes to enjoy a longer playtime. For example, if you are taller than average (2m+), you will most likely not be able to use the power saving mode. Power saving: 24 hours Balanced: 14 hours Performance: 8-10 hours
-
Can I add aditional trackers to a kit?Yes, of course. Our kits are designed to provide a simple starting point, ensuring you get all the devices you need for a given application. You can at any point, add more devices to the system.
-
How many trackers can I use at the same time?There is NO theoretical limit on how many trackers you can use simultaneously in a given system. Nevertheless, right now only one beacon can be active a time. Support for multiple beacons will be available later on through a firmware update. The charging dock (and each dongle) is able to handle up to 10 devices, so if you want to have more devices at the same time you will need to use additional dongles.
-
Can I use FluxPose for non-VR applications?Yessss! FluxPose is designed from the ground-up to be very versatile and can be used beyond VR for motion capture, robotics and more. You can set any device as a spatial anchor and it will act as a reference point for the rest of the system. For example, in VR applications we automatically set this spatial anchor to an OpenVR HMD. Through the locally available API you can get the position, rotation and many other parameters of all the devices in the system.
-
Can I customize the text on the screens or the HUB leds?Yes, you can change a huge amount of parameters in the advanced mode of the FluxPose UI. The Dock LED colors and the screen contents are just some of them 😉
-
The charging dock LEDs are too bright at night. Can I turn them off?You can turn off all the lights in the system by long pressing on the dock button until the lights turn off. Interacting with the dock in any way (touching the button, plugging a device...) will turn the lights on again.
-
Can I use the trackers under a blanket?Yes! The trackers are completely occlusion free. This means you can use them under a blanket, clothes or in general any non-metallic object.
-
What does the LED colors mean?As a general rule of thumb, green=good, red=bad, blue=connecting/connected. For more detailed information, please check the user manual in the Downloads page.
-
Is FluxPose affected by nearby metal?FluxPose, as all EMF tracking systems, can suffer from accuracy loss near metal. We have minimized these effects by keeping the trackers and the beacon as close as possible and calibrating the effect of known objects like HMDs (headsets). Users can also create their own calibration to compensate for metal on their tracked objects. For VRChat full‑body tracking, the built‑in calibration cancels most remaining offsets under normal scenarios. Are you designing an accessory or want to integrate FluxPose in your project? Check out our documentation in the downloads page to learn where to avoid placing metal and which metals have a lower effect.
-
Is FluxPose affected by electronic interference?Usually not. Keeping the tracker just a few centimeters away from noisy electronics is usually enough to prevent any interference. For example, we have integrated our trackers with many VR HMDs and we haven't encountered any major issues.
-
What is 6DOF+ mode and when should I use it?If you are using 2 trackers per leg, you can turn on the 6DOF+ mode. (And we highly recommend it) 6DOF+ is our enhanced tracking mode, which refines the 6DOF position of your feet trackers with data from a kinematic model of your leg. This kinematic model is specifically tailored to your body through a one-time calibration performed in 6DOF mode. 6DOF+ generally doesn't have any drawbacks vs regular 6DOF, and is especially useful if you are very tall or your floor has tons of metal.
-
What is the range of the FluxPose system? Can I use the beacon as a stationary base-station?The absolute maximum tracking range for the tracker is a 3.2m diameter sphere around the beacon. So, if you wear the beacon on your waist, you can track anything around you, no matter where you are in space (for example you can move to a different room as the tracking volume moves with you, granted your HMD allows it). Nevertheless, the tracking performance degrades the further you go in this volume. (Check the datasheet in the Downloads page for more information). For FBT, we don't recommend using the beacon as a stationary base-station, because even though the hardware/software supports it, having it in your waist is just much better in nearly all situations.
