Tobii Glasses X — Eye tracking glasses for research in the field — no calibration

Lightweight glasses with a camera that records what the participant sees, and cameras that track their eyes. The recording shows where they were looking at every moment — at a machine, at a store shelf, behind the wheel. Put them on, connect to a phone and record.

What Glasses X are

A camera on the world, cameras on the eyes

An eye tracker measures where a person is looking. In Glasses X, a camera above the nose films what is in front of the participant, and two small cameras inside the frame observe the eyes in infrared light. From the position of the pupil and the light reflection on the eye, the algorithm calculates the gaze direction — and maps it as a point onto the video of the surroundings.

1
Scene cameraOn the bridge above the nose. It films what is in front of the participant: 2560 × 1440 pixels, 30 fps, 118° horizontal and 67° vertical angle.
2
Eye cameras and infraredOne camera for each eye and 18 infrared LEDs (9 per eye) along the inner edge of the frame. The light is invisible to the participant.
3
Nose pad with coverKeeps the glasses on the nose; an additional cover improves the fit.
+
Stereo microphones and head motion sensorsAmbient sound (48 kHz) plus a gyroscope, accelerometer and magnetometer — you know how the head moved.
+
USB-C cable to the phone1.2 m; the cable carries data and power for the glasses. The whole unit with the cable weighs 72 g.

No calibration

The participant does not have to look at calibration points. They put on the glasses and the study can begin — this shortens preparation in a factory hall, a store or on the court.

Fixed geometry

The eye cameras and the scene camera are rigidly mounted relative to each other, so the eye position can be translated directly into a point in the scene image.

The glasses may slip

The manufacturer uses a three-dimensional eye model that compensates for the glasses shifting on the nose during movement. Pupil size is measured in absolute values.

One recording — five synchronized tracks

The app records everything on a common timeline. That is why at any moment of the recording you can see at the same time: what was in front of the participant, where they looked, how the pupil changed and how they moved their head.

From putting on the glasses to team insights

Glasses X were designed for research outside the lab: at the production line, in a store, in a car. That is why the whole system is the glasses, a phone and cloud software — with no separate recording unit and no computer next to the participant.

Why Glasses X with Interlab

Glasses and software from one manufacturer

Subscription platforms to which you connect glasses from other companies are popular. Glasses X take a different approach: the glasses, the app and the analysis software come from Tobii and work together from day one — and we help you put them into use.

Accuracy without calibration

What 1.5–2.5° means in practice

Eye tracker accuracy is given in degrees of visual angle, because the error grows with distance from the eye. Without calibration, Glasses X have an accuracy of 1.5–2.5° — the manufacturer classifies it as “enterprise” grade, for use in companies and training. See how large this margin is at different distances.

Enough to show which product on the shelf the customer looked at and how much time they spent on it.

When a single word on a label or a small interface element matters, higher accuracy is needed: Tobii Pro Glasses 3 — 0.6° after one-point calibration.

Applications

Wherever attention determines the outcome

The manufacturer designed Glasses X for training and skills transfer, quality improvement in production, workflow analysis, consumer research, human factors, engineering, education and healthcare.

Training and quality control

A recording of an experienced worker shows what they look at during assembly or inspection — knowledge that is hard to put into words. New employees learn from their example, and the trainer sees where they need support.

Frequently asked questions

Do the glasses need to be calibrated before recording?

No. The participant puts on the glasses, and recording starts from the app on the phone. The trade-off for no calibration is an accuracy of 1.5–2.5° — enough to determine which object or area the participant is looking at. For measurements requiring 0.6°, there is Tobii Pro Glasses 3.

Is an internet connection needed during recording?

No. The app also records when the phone is disconnected from Wi-Fi and the cellular network. Data is stored temporarily on the phone and uploaded to the cloud automatically. Remote live view, of course, requires a connection.

Can people who wear prescription glasses take part in studies with them?

Yes — with the corrective lens kit from −6 to +3 diopters, attached to Glasses X. For work in the sun there is a sunglasses clip-on.

Will I get raw data for statistics?

Not in Glasses Explore: it is a tool for visual insights, tagging and comparisons. Raw data, areas of interest, heat maps and custom metrics are provided by Tobii Pro Lab, into which you import recordings from Glasses Explore.

Can Glasses X be connected to EEG or physiological measurement?

No — Glasses X do not work with BIOPAC systems and have no TTL synchronization port; the manufacturer describes their integration as basic sensor data. For multimodal research we offer Tobii Pro Glasses 3 with a BIOPAC system — we will put together the configuration. Tell us about your study.

What is included?

Tobii Glasses X, a one-year Glasses Explore license (up to three glasses), access to storage and features in the cloud, plus support and training materials from the manufacturer. We will confirm the list of compatible Android phones and the Tobii Pro Lab license in our quote.

Where are the recordings stored?

In the manufacturer's cloud: data is stored with AES-256 encryption, transmitted with TLS 1.2 or later, and keys are managed in AWS Key Management Services. Sign-in is provided by Auth0, with role-based access control.
