What are Eye Tracking Glasses?


Eye tracking glasses record what someone is looking at. Buy Kexxu €799 eye tracking glasses for marketing, product research, user experience design, sports analytics, and more.

Our wearable eye tracker can make gaze recordings by recording the eye with one eye tracking camera, and recording the scene with another camera.

Artificial intelligence runs on the camera recording the eye, to determine the center of the pupil in real-time.

Using the pupil location a crosshair is drawn on the camera recording the scene. This way you can see in real-time where the person is looking at in a scene.

AI Pupil Tracking Software


By combining our eye tracking hardware with our eye tracking software that runs in the cloud, you can leverage modern AI pupil tracking software to measure important gaze duration statistics. Gaze duration or dwell time indicates how long a participant looked at something.

Usually you will be interested in relative dwell time. Is the dwell time longer for the blue, or the red packaging?

Using editor.kexxu.com, it's very easy to create dwell time comparison diagrams comparing different Areas of Interest.

If you create an account, there will be an example video where dwell time is calculated for three Areas of Interest.

Fully Portable


The eye tracker consists of the glasses, and the processing unit attached to the glasses. All processing happens on this portable unit in real time. It can save up to 16 hours of recording, before you have to upload your data to the Kexxu cloud editor.

With a battery life of 6 hours, you can record the entire day with just one charge. The battery can easily be taken out to be swapped or charged. On the back of the processing device, the current battery percentage is displayed.

Area of Interest Eye Tracking


In our eye-tracking free cloud analysis tools, you can mark Areas of Interest in your eye-tracking recordings. Our cloud tools provide insights into anything you want to know about the areas of interest. For instance, gaze duration per area of interest or time to focus.

Time to focus measures how long it takes somebody to notice something in the environment. The timer starts when the area of interest comes into view, and it stops when the person looks directly at the area of interest. As an example, consider a warning light on the dashboard turning on.

Using editor.kexxu.com, it’s very easy to create time to focus comparison diagrams, with AI assistance.

Heat Maps


In our online eye tracking interface, it is very easy to create heat maps of your eye tracking recordings. Heat maps are the easiest and fastest way to get a quick insight in your eye tracking data.

Using artificial intelligence, we compensate for any head movements. This way, we can create a stable heat map of focus points even when walking through the environment with our wearable eye tracking glasses.

You can create a heat map of your eye tracking experiment with one button press on editor.kexxu.com.

Gaze Plots


A gaze plot can visualize saccades and the order of saccades.

Everybody moves their eyes in the same two ways: Tracking and saccades. Tracking is when you follow an object, or fixate on an object while moving yourself. Saccades move the eye from one tracking location to another tracking location. Saccades happen 3 to 7 times per second, and are visualized with a Gaze Plot.

You can create a gaze plot of your eye tracking experiment with one button press on editor.kexxu.com.

Basic Eye Tracking Experiment


You start an experiment by convincing a test subject to put on the Kexxu Eye tracking glasses. The glasses will be connected to the Kexxu Devices app, in which you can preview the video that is recorded and where the subject is looking. First you start with calibrating the eye tracker.

To calibrate the eye tracker, adjust the AI camera window so it fits perfectly over the eye, so the eye tracking AI can do it’s work. After that make the subject look at a point in the center of his field of view. The gaze cross will not point to that location initially, so you adjust the gaze cross with buttons in the app so the cross is exactly at the point the test subject is looking at.

For some eyes the sensitivity is different. What do we mean by this? When you make the subject look at a point to the left and to the right, the gaze cross can overshoot or undershoot the target. Adjust the sensitivity in the app so the gaza cross is exactly on target not only for the center but also for the sides. Do the same for up and down. The sensitivity will usually only have to be slightly adjusted.

After that you press record to start recording eye movement. Important now is that you give the test subject an instruction. Eye movements and gaze locations differ a lot based on the instruction. For example asking to find the cheapest product will give a different gaze plot than asking to find the highest quality product.

When the experiment is finished you can press stop recording. The recording will be saved on the eye tracking glasses, but will be visible in a list in the app, where you can press “upload to cloud”. When the video is uploaded to the cloud you can go to the cloud editor to create gaze plots, heat maps and mark areas of interest to compare statistically.
