Launching October 15EKE TRACKER BV

you are wearing it

8.5mm thin, 10.9g each, full-body tracking. See you on October 15.

If everything is ready sooner, we may launch earlier than planned. Sign up and we will tell you the moment it happens.

EKE Tracker BV
Thickness 8.5mmEach 10.9g6 points all wirelessCharging dock included

Bring your legs and hips
into VR

Attach six points to your body and the lower-body movement a headset and controllers cannot see follows you exactly. Sitting, lying down and walking all show up on your avatar.

The complaint we heard most often from people already using trackers was "they are thick and heavy enough that I notice them". So we started with thickness and weight. Charging is just leaving them in the dock; to use them you take them out and put them on.

Small enough to sit on a credit card

So it
gets thinner

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.

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.

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.

EKE Dongle B

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.

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 recalibration45–50 min25–30 min

Roughly twice as long between calibrations.

EKE Tracker BV

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.

We are not claiming a winner — just the numbers, laid out. The judgement is yours.

Comparison figures are based on catalogue specifications and store listings published by each manufacturer. Please check each manufacturer’s official information for the latest specifications.

Comparisons assume a 6-point fully wireless configuration; other manufacturers’ figures are rounded approximations.

The weight of EKE Tracker BV is for one finished unit including battery and case. Velcro tape is optional and therefore not included in the figure.

Bundled items and accessories differ, so prices are not directly comparable.

Here is where we are

Design and prototyping are done. What remains is certification and the first production run.

DesignDone
We designed the board, firmware and case ourselves — trackers, dongle and dock all in-house.
PrototypeDone
We are producing actual units and testing them to make the product as good as it can be.
Firmware refinementIn progress
We keep working on wireless stability and pose correction. Improvements after launch can be applied as updates.
KC registration (radio certification)In progress
A required step before selling wireless devices in Korea.
First production orderRemaining
We decide the initial quantity based on how many people sign up.
Sales begin — planned for October 15Remaining
If the steps above finish sooner, we may launch earlier than planned. Earlier or on schedule, everyone who signed up hears first.

Questions you may have

When does it come out?
Launch is planned for October 15. If certification and the first production run finish before then, it may launch earlier. It could also slip if the process takes longer, which is why we say "planned". Earlier or later, everyone who signed up hears first.
What do I need?
A Windows PC and a program (SlimeVR server). It is used in a SteamVR environment, so it does not work with a headset alone.
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?
Yes. It starts at the launch price of US$249. After the launch period it will sell for US$299, and we will announce the period when sales begin.
Can I buy it from outside Korea?
A separate purchase page is planned. Customs duties, VAT and shipping vary by country and are charged separately.
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 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.
Does it come in only one colour?
For now it ships in a single colour. We plan to let you choose a colour later, which will carry an additional charge.

Please note

This page is not an order or payment page. We take no deposit or prepayment, and leaving your contact details creates no obligation to buy.

Sales begin after KC registration (radio certification) is complete.

The October 15 launch is a plan and may move earlier or later depending on readiness. The contents of the set may also change.

Battery life is measured in-house with continuous use at about 25°C indoors, from full charge to automatic shutdown. It varies with your environment.

A Windows PC and the SlimeVR server are required. The product is used in a SteamVR environment and does not work with a headset alone.

Intended for users aged 14 and over.

Some product images are 3D renders and may differ from the actual product. Colours may vary depending on your monitor.
