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.

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. We currently support Microsoft Windows 7,8 and 10, as well as Mac OSX and we are working on support for additional 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 then 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 that fits either the Microsoft Surface Pro 1/2 or Surface Pro 3 tablets. Snap it on and take eye tracking on the go.

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 ordered The Eye Tribe Tracker. When will my credit card be charged?

Your credit card is charged when you place the order.

Is infrared illumination safe to use?

Yes, The Eye Tribe Tracker complies with the essential health and safety requirements set by the FCC and CE directives. The Eye Tribe Tracker is using near-infrared illumination, it conforms with the EN 62471 standard and we have obtained an EU declaration of conformity.

Our hardware has been tested and approved by a certified lab according to said standard, and is therefore safe to use.

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 GazeSpeaker)

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.

Is your product CE / FCC / IC certified?

Will it work for people with disabilities?

The Eye Tribe Tracker can certainly be used quite effectively by some persons with disabilities, such as ALS, but it might not work for all situations or every person, since we are still a start-up, we do not have the resources to test our technology for all disabilities and situations.

It is important to note that currently our tracker is offered as a software development kit for programmers and developers and is not yet a commercial/end-consumer product. Hence the support we can offer is limited. However, we are hoping that people will help us evaluate and test the software for different situations and various disabilities, and provide the relevant feedback in our forum.

We do not provide any attachments for wheelchairs or hospital beds, nor any dedicated software for individuals requiring assistive technology, however, some applications already work with our hard- and software. At the present time we suggest taking a look at the following software applications:


At the present time the programs listed above are all freeware and offer various input and eye tracking functionality in connection with the Eye Tribe Tracker. We suggest taking a look at the direct links we have provided for each program and learn more about what best suits your current situation and requirements.

As with all new and groundbreaking technology, updated software and new applications with ever-increasing functionality are developed every day. Thus there may be additional software available that we are not aware of.

Will it work on any OS?

The first version being shipped is for Windows (7,8 and 10), and an OSX version was made available in June 2014.

The hardware is the same for Windows, OSX and Android (TBA) versions of the software.
