Affordable eye tracking is finally here

Making eye tracking available for everyone is the driving force behind everything we do. We believe that the true potential can only be reached once this technology has become widely available.

Our small device represents a major breakthrough in eye tracking. It is the world’s smallest eye tracker, the first to use USB 3.0 and the only alternative below the magical price point of $100.

* 1st batch of The Eye Tribe Tracker is completely sold out * Pre-order now for 2nd batch, Spring 2014 delivery!


One-cable convenience, USB versatility

Given the small form factor and the standard USB 3.0 connection this device is truly versatile, it runs with most newer desktops, laptops and tablets.

Since it does not require a separate power supply you can use it wherever you go. The device is build on standards which means that there is no firmware or drivers that needs to be installed. Just plug it in and launch the software.

The first release will support Microsoft Windows 7 or newer, but we are working on support for other major platforms.

Building applications

Simple SDK. Open API

We’ve made sure that accessing the data is really easy while maintaining flexibility to support many scenarios. To quickly get you started we provide an SDK with implementations in C++, C# and Java (full source code included).

All it takes is a few lines of code and your apps will receive a real-time stream of on-screen gaze coordinates. If you favor any other programming language the open API relies on the standard TCP/IP protocol. If it can open a socket and parse strings you’re covered.


Accurate and robust

A brand new sensor combined with the infrared illumination system provides the very best conditions for the eye tracking algorithms to work with. The high resolution sensor ensures that we can track the tiny movements of the pupils with high precision while maintaining a wide field of view.

Our advanced algorithms work in tandem with the hardware to optimize for most environments and light conditions. However, it works best in indoor scenarios without direct sunlight on the device.



Setting a new standard for portability

We wanted this device to be as small as possible without becoming fragile or sacrificing functionality. When you hold it in your hand it feels solid and remarkably simple. It is a true engineering feat to take something this advanced and transforming it to such a small device. Measuring 20 x 1.9 x 1.9 cm this is the smallest eye tracker in the world.

 To ensure that the device doesn’t scratch any surfaces we’ve covered the back with a smooth rubber surface. At the bottom we placed a standard tripod screw thread that allows any tripod or mount to be used.

We are offering a custom mount for the Surface Pro tablet. Snap it on and take eye tracking on the go.

Frequently asked questions regarding The Eye Tribe Tracker

Are there any limitations on how I may use The Eye Tribe Tracker?

No, we are really excited to see what you will build with it! Please keep us posted in the developer forum.

Can I pay with different credit cards other than Visa or MasterCard?

At the present time we offer only those two options during our normal check-out process. If you do not have access to a Visa or MasterCard, you may contact to arrange payment via Paypal.

Do you sell it in any stores?

No, not yet. At this stage we only sell and distribute the device directly from our website.

How accurate is the system?

The Eye Tribe Tracker can detect the movement of the pupil with sub-millimeter precision. The average accuracy is around 0.5 degree of visual angle, which means that the system is capable of determining the on-screen gaze position roughly within the size of a fingertip (<10mm).

I have just pre-ordered The Eye Tribe Tracker. When will my credit card be charged?

Your credit card is charged when you place the order, however the money is put into a deposit account with the bank. The Eye Tribe will not have access to the funds, until we actually ship the device to you.

Is infrared illumination safe to use?

Yes, The Eye Tribe Tracker will comply with the essential health and safety requirements set by the FCC and CE directives.

Is it only for developers ?

At this stage The Eye Tribe Tracker is not bundled with any applications for common use, and is intended only for software developers. We hope developers around the world will create great applications with eye control, that we can make available. (Out of the box it will support eye controlled mouse cursor, which can already be used with third party applications such as GazeTalk)

Is there a developer forum?

Yes, indeed there is. We post sample applications and provide developer guidelines.

Is there any way to try the device before purchase?

We will be attending several conferences and exhibitions during the year to showcase The Eye Tribe Tracker. Follow us on Facebook ( to see where and when to meet us.

When are you shipping the device?

The first devices were shipped out in December 2013. We are currently shipping all orders as fast as we can. Please be patient, we are doing everything we can. You will receive an email as soon as your order leaves our warehouse. If you have questions regarding delivery of your package please email us at

Will it work for people with disabilities?

Yes, but we do not provide any attachments for wheelchairs or hospital beds, nor any dedicated software for individuals requiring assistive technology. However, it can be used with some third-party communication software such as GazeTalk.

Will it work on any OS?

The first version being shipped is for Windows (7 and 8), but we expect to make an OS X version available in April/May 2014. The hardware is the same for these two versions of the software, so you can go ahead and order the device today even though you are interested in the OS X version, and want to make sure you have the device when the software is released.

We expect to provide software updates for all other major platforms in the near future, but for some platforms you might need a different piece of hardware. Please follow us on Facebook and Twitter for future announcements.

Will it work on everyone?

The Eye Tribe Tracker will work on almost anyone that has “normal” eyes. Age or ethnicity makes no difference. However, there are certain medical conditions that limit the capability of the system such as strabismus, esotropia, exotropia and similar.

Will it work with any other tablets than the Windows Surface Pro?

Yes, it will work on any tablet with Windows 7 or newer, that has USB 3.0, but at this stage we only supply an attachment mount for the Windows Surface Pro tablet.

Will it work with contact lenses?

Yes, there are no issues with normal soft contact lenses.

Will it work with glasses?

Yes, it will work with most glasses. However, there can be issues with bifocals and other special lenses, or glasses that have coating – including polarized glasses.

Will it work with USB 2.0?

No. The system is optimized for USB 3.0 only. If your computer does not have native USB 3.0 support, the Eye Tribe Tracker will also work with 3rd party USB 3.0 PCI cards. Although we do not offer support for these, we have successfully used USB 3.0 PCI cards from Sandberg, ST Lab and Delock.
