EKE TRACKER BV
Slim, lightweight full-body trackers
Smaller than a card, just 8.5mm thin
신용카드 85.6 × 54mm 옆에 나란히 놓은 실물.트래커 바닥면은 36 × 36mm예요
What makes full-body trackers uncomfortable is usually not weight but thickness.A thick device makes itself known the moment you lie down, lean back, or sit on the floor.With the strap, the EKE Tracker still comes in under a centimetre, and it barely shows through clothing.
Seen from the side · case dimensions 36 × 36 × 8.5mm (3D render)
※ Thickness is the designed case dimension and excludes the strap and hook-and-loop tape.
10.9g each
About two coins
All six together come to 65g, lighter than a phone.
배터리·기판·케이스·뚜껑까지 전부 포함한 완제품 한 개의 무게
Lighter at the ankle changes how you walk; lighter at the thigh changes standing up and sitting down.Over a long session that is where the difference is felt most.
※ 10.9g is the measured weight of one finished unit including battery, board, case and lid, excluding the hook-and-loop tape.The 65.4g figure for six is 10.9g × 6 and excludes straps and tape.
※ Two Korean 100-won coins weigh 10.84g (Bank of Korea published specification).
The only thing touching you is the strap
Two things come up again and again from people who wear trackers for hours.
"The tracker hurts where it touches"
When a hard case sits straight on the body, it is your skin that gives out first after a few hours.
"It left a bruise where it pressed"
The tighter it is cinched so it will not slide, the harder one edge keeps pushing on the same spot.
The EKE Tracker attaches to the outside of the strap with hook-and-loop tape.What touches you is the strap fabric, with the tracker riding on top of it.At 8.5mm and 10.9g it stays in place without being cinched hard.
It takes longer for your pose to drift
LSM6DSV 6-axis sensor · temperature calibration completed before shipping
Use full-body trackers for a while and your legs slowly rotate out of place until you recalibrate.That is drift — small errors accumulating in the gyroscope.
How long it holds comes down to which sensor is inside.The official SlimeVR documentation publishes a grade table of how long each sensor lasts before recalibration.

Time to recalibration

Roughly twice as long between calibrations.
Gyroscopes drift slightly as the device warms up, which is why temperature calibration matters.EKE Tracker BV has this calibration completed on every unit before it ships.There is nothing for you to do — just use them as they arrive.
※ Sensor comparison figures are quoted from the sensor grade table published in the official SlimeVR documentation (as of August 2026) and describe the sensor component itself.
※ Actual hold time on a finished product varies with where it is worn, the type and intensity of movement, ambient temperature and unit-to-unit variation.
※ Gradual pose drift is inherent to 6-axis trackers and cannot be eliminated entirely.For long sessions we recommend recalibrating once in a while.
A small battery lasts long because we do not use Wi-Fi
Most wireless trackers communicate over Wi-Fi.Wi-Fi is convenient, but it draws a lot of power.EKE Tracker BV talks directly to its own dongle over dedicated 2.4GHz wireless.Nothing passes through a router, so it uses far less power.

So it gets thinner
Up to 48 hours of continuous use
One charge lasts you the whole week.
Automatic sleep
They fall asleep on their own when still and wake the moment you move.No need to switch them off.
Docked means charged
Drop them in the dock after playing and charge is never a worry next time.
※ Battery life is measured in-house (about 25°C indoors, continuous use, from full charge to automatic shutdown) and varies with your environment, how much you move and your settings.
※ Batteries are consumable; run time decreases as charge cycles accumulate.
Drop them in and you are done
A six-slot docking station is part of the set, so there are no six charging cables to plug in.
세트에 포함된 6구 도킹 스테이션.오른쪽 끝은 동글 자리예요
Charging
Drop all six in and they charge at once.
Storage
Back in place after playing.No hunting for six of them next time.
A slot for the dongle
The dongle sits in the dock and talks to the PC from there.
One cable from the dock to the PC is the whole setup.Six trackers charge, and the dongle keeps communicating from its slot.One cable is all that is left on the desk.
※ Only the dongle communicates with the PC over USB from the dock.Tracker firmware goes over the air through the dongle, so you can update them while they sit in the dock.It is actually faster that way.
No router setup
Plug in the dongle and that is it.No entering Wi-Fi details on each tracker, no channel settings to fiddle with.There is no router in the picture to begin with.
Change PCs and you only move the dongle
Moving from your desktop to a laptop? Pull the dongle out and plug it into the laptop.Nothing to reconfigure.Pairing stays as it was.
Take it to a friend’s place or sit somewhere else — it works the same.
There is barely an installation to speak of.Install one program on your PC, plug in the dongle, done.The six trackers are already paired when they ship.
※ Wireless range and stability depend on the radio environment around you, obstacles such as walls and furniture, where the trackers are worn, and radio noise from your PC and nearby devices.
※ Plugging the dongle directly into the PC chassis can expose it to noise.We recommend using the included cable and dock to place it as far from the PC as possible and close to where you play.
A simple start, even the first time
Install SlimeVR Server, connect the dongle, and switch on the trackers.All six ship already paired, so there is no Wi-Fi name or password to enter.
1Install SlimeVR Server
Install SlimeVR Server on your PC.Run SteamVR once before installation.
2Plug in the dongle
Connect the docking station to the PC and put the dongle in its slot, or plug it straight into the PC.The server recognises it automatically.There is no driver to install.
3Switch on and assign positions
Switch on all six and assign them to your chest, waist, thighs and ankles.Mounting calibration and body proportions only need setting the first time.
※ For mounting calibration, body proportions and full instructions, see the online manual through the QR code in the box.
Update wirelessly, without plugging in each tracker
No separate app to install
Connect the dongle to your PC and open the update page in your web browser.You can update your trackers wirelessly.
New firmware is free, with no time limit.
PCVR and PC-free setups
The specifications and setup steps below describe our tested Windows 10/11 PCVR environment.
Any headset that runs SteamVR
It is not built around one headset, so the model barely matters.
SteamVR · PC requirements follow the headset and game you already use · no extra requirement from the trackers
USB port
One, for the dongle · with the docking station, one cable covers charging too
Software
SlimeVR Server · Free · from the official site, slimevr.dev
Internet
Needed for setup only · not needed while playing
Router
Not needed · trackers talk to the dongle directly
※ The specifications and setup steps below describe our tested Windows 10/11 PCVR environment.
※ The headset and game lists above are taken from the SlimeVR official compatibility list and are not exhaustive.Trademarks belong to their owners, and we do not warrant operation on every device or in every game.Support can change if a game publisher changes its policy.
※ Our own test environment is Windows 10 · 11.SlimeVR Server itself also supports Linux and macOS, but that is outside what we have verified.
An Android phone can replace the PC
Run the official SlimeVR app on an Android phone, connect the USB dongle, and send OSC data to VRChat on a Quest on the same network.The phone needs USB host (OTG) support, any required adapter, and OSC configuration.
Installing SlimeVR directly on a Quest is also possible, but the official documentation does not recommend this approach because of app issues on Quest OS.
The standard set covers chest, waist, thighs and ankles: six places.Add elbows and the upper body follows; add feet and your toes do.

The dongle stays
Only the new tracker needs pairing: hold the dongle button for 5 seconds, then the tracker button for 5 seconds, and both lights blink three times.
A ten-slot dock
More trackers need more charging slots, so a ten-slot version is in preparation on the same design.
The sticker sheet already has eleven
The placement sticker sheet in the set covers all eleven usable positions.It is there for the ones you might add later.
※ Individual trackers and dongles, and the ten-slot dock, are still in preparation.We will announce them when they go on sale; what is on sale now is the six-point set.
※ One dongle can register up to 16 trackers.We recommend connecting no more than 10 per dongle.
※ More positions need that many more straps and tapes.Individual trackers ship with them included.
Materials & packaging
From the case you wear to the packaging you receive
The case uses plant-derived PLA.The packaging uses recycled pulp and FSC-certified paper.

Carbon origin

Underground for aeons
Emissions unit: kg CO₂e
Plant carbon in the material
While the corn grows it pulls carbon dioxide out of the atmosphere by photosynthesis, and that carbon stays locked inside the case.Roughly 1.8kg of CO₂ is held in every kilogram of the material.All plastic parts of EKE Tracker BV use this material.
It is not made from corn people eat
The feedstock is not sweet corn but field corn grown for starch and animal feed.Only the starch is taken; the protein and fibre left over go back into feed.Nothing is grown and then thrown away.
Nor does it take land from food.0.013% of the world's agricultural area grows feedstock for bioplastics.Nearly all the rest goes to food and feed.Even a several-fold increase in production would keep that share under one percent.
Packaging made with recycled pulp and FSC-certified paper
The packaging paper is blended with recycled pulp, fibre from paper that has already been used once, so that much less new material goes into it.
The rest does not come from just any forest.FSC certification requires that what is cut is replanted, that no old-growth forest is cleared to make a plantation, and that wildlife reserves are kept within the forest.An independent body audits those conditions every year.
Printing is limited to one colour and the surface carries no coating, so the box goes into the paper bin exactly as you opened it.
A box is thrown away within a day.We saw no reason to cut into a forest for that day.
The tracker works the same whatever the packaging is made of.That makes this the easiest place on the whole product to save money, and nobody would ever notice.We did not save it here.What goes into the parts you never see is what tells you about the parts you do.

Questions you may have
When does it come out?
Launches October 15. Dispatch starts on October 15.Orders may open before launch.We will notify everyone who signed up when orders open.Check the purchase section for your estimated dispatch date, which depends on your colours, production and material availability.
What do I need?
Tested with Windows PCs.See system requirements for PC-free setups using Android. Run the official SlimeVR app on an Android phone, connect the USB dongle, and send OSC data to VRChat on a Quest on the same network.The phone needs USB host (OTG) support, any required adapter, and OSC configuration.
Can I use it with other trackers?
It runs on SlimeVR, so it works alongside other SlimeVR trackers.Vive trackers need manual binding and similar fiddly steps, and we cannot offer technical support for that, so we recommend sticking to our trackers where possible.
Am I obliged to buy if I sign up?
No.You are not paying anything now and there is no obligation to purchase.Tell us any time if you would like to stop receiving the notification.
Is the price final?
Not yet.We currently estimate around US$220 at the launch price and around US$240 at the regular price.The price is finalised after radio certification (KC) and the first production run, and will be announced when sales begin.
Can I buy it from outside Korea?
Yes.From outside Korea you buy it on this page.It meets the Japanese technical conformity requirements.Customs duties, VAT and shipping vary by country and are charged separately, and delivery takes longer than domestic shipping.
What is in the box?
6 trackers, 6 tracker straps, 6 velcro stickers for attaching the trackers, 1 USB-C cable, 1 dongle for PC communication, and 1 charging dock for the trackers.
How many trackers, and how many are supported?
The set comes with 6 trackers, worn on the chest, waist, both thighs and both ankles.We recommend up to 10 per dongle, and the spec allows pairing up to 16.The 4 points beyond the basic 6 are both elbows and both insteps.Elbows let you fold your arms and flap them, insteps let you stand on tiptoe.Extra trackers will be sold separately, and a dock that charges 10 trackers at once is in preparation.
How do I use it?
Plug the dongle into the charging dock, connect the dock to your PC, install SlimeVR, and you are ready to go.It uses the 2.4GHz band, so placing it right next to a USB 3.0 port can cause interference.Keep the dongle as far from the PC as you can, close to your play space, which is why we include a 2 m USB cable.
How do I wear it?
You put on the straps we include and attach the trackers with velcro.The trackers are light enough that velcro alone holds them.Straps and velcro stickers are in the box, so there is nothing else to prepare.
Is there drift? Does it calibrate itself?
Gyro calibration for temperature is done before shipping.Drift that builds up over a long session, however, is not corrected automatically.That is how SlimeVR-based trackers work.We minimised it by using the highest-grade sensor SlimeVR officially supports, and by the official documentation that means more than twice the hold time of other products.Your body twisting when you lie down is a physical limitation, which we compensate for with the straps as much as we can.
Does it come in only one colour?
You can choose colours and finishes for the trackers, dongle and dock, with separate body and lid choices for the trackers and dongle.Non-default combinations are made to order (CTO).The purchase panel shows the surcharge and estimated delivery for your selection.
Does it work on a Quest alone, without a PC?
Run the official SlimeVR app on an Android phone, connect the USB dongle, and send OSC data to VRChat on a Quest on the same network.The phone needs USB host (OTG) support, any required adapter, and OSC configuration. Installing SlimeVR directly on a Quest is also possible, but the official documentation does not recommend this approach because of app issues on Quest OS.
Is there a magnetometer?
No, these are 6-axis.Instead they use a sensor one tier up and ship with temperature calibration already done, which reduces how far the pose drifts.
Can I plug the dongle straight into the PC?
You can.Right next to the case, though, and especially beside a USB 3.0 port, there is enough radio noise to shorten the range.We recommend the bundled cable and the docking station so the dongle sits as far from the PC and as close to where you play as possible.
Can I update the firmware while it is in the dock?
Yes.Tracker firmware goes over the air through the dongle, so leaving them in the dock is actually the faster way.The dongle itself is plugged into the PC, so it updates as it is.If the radio struggles, move the trackers closer to the dongle and try again.
SlimeVR Server says “timed out”
Nothing is broken.Left alone for a while a tracker goes to sleep on its own and shows up that way.The smallest movement wakes it and it comes straight back.
SlimeVR Server does not show latency (ms)
SlimeVR Server does not display latency for USB-type trackers.It is not a fault.Signal strength, packets per second and battery all show normally.
The battery percentage disappears while charging
SlimeVR Server is built to hide the percentage while charging.That is normal.
