Browse the departmentTobii Pro Lab presents stimuli to the participant, records their eye movements and turns the recording into heat maps, gaze plots and ready-made metrics for statistics. No programming, in one program — with screen-based eye trackers, Tobii glasses and a webcam.
An eye tracker measures where a person is looking — but the measurement alone is a stream of numbers. Pro Lab organizes the whole study: it decides what the participant sees and when, records gaze synchronized with the stimuli, then shows the results on the image and calculates metrics from them. The software has three modules — Design, Record and Analyze — one for each stage.
You build the study from blocks in a visual editor: what the participant sees, in what order and what advances to the next screen.
Pro Lab controls the eye tracker and stimulus presentation in one program, so every gaze sample is tied to a moment and a stimulus.
You replay the recording on a timeline with events and overlay the results on the stimulus — for one person or the whole group.
A fixation filter organizes the raw data, and Pro Lab calculates ready-made metrics from it — for areas, time intervals and participants.
An eye tracker records the gaze point many times per second — in Tobii screen-based eye trackers from 60 (Pro Spark) to 1200 times (Pro Spectrum). Pro Lab organizes these points: it groups them into fixations, shows them on the stimulus and calculates metrics for selected areas. Go through the stages using the example of a task with four products.
| Area | Time to 1st fixation | Fixation count | Total fixation duration | Visits |
|---|---|---|---|---|
| Orange | 0.24 s | 3 | 0.72 s | 2 |
| Ice cream | 1.83 s | 2 | 0.46 s | 1 |
| Dress | 0.81 s | 3 | 1.04 s | 2 |
| Ice skates | 1.57 s | 1 | 0.22 s | 1 |
Illustration: points, fixations and metrics generated in the browser — this is not a Pro Lab recording. Screen photo: Tobii. Description of the I-VT filter, visualizations and metrics according to the Tobii Pro Lab documentation.
The metrics are defined in the Pro Lab documentation, so in a publication you state exactly what was calculated and with which filter. Blinks are detected by an algorithm described in the literature (Nyström et al., 2024).
Pro Lab works with current Tobii eye trackers. You choose the project type in the software to match the hardware and the study setting: at a monitor, in the field or remotely.
A bar below the monitor, the participant looks at stimuli presented by Pro Lab. You choose the model by how closely you want to study eye movement — from fixations to microsaccades.
Research on the move — in a store, on the factory floor, behind the wheel. The glasses’ camera records the scene, and Pro Lab maps gaze from the moving video onto a still photo of the location (assisted mapping, Real World Mapping algorithm).
Since version 26.18, Pro Lab officially supports webcam eye tracking — you run a screen-based study just as you would with a dedicated eye tracker.
Participants take part from home, using their own webcams — no special hardware. You design and launch the study online in Tobii Sticky, then import the data into Pro Lab for visualization and analysis (Distributed Online edition).
If you already have your paradigm in E-Prime, that program presents the stimuli and runs the calibration, while Pro Lab records and analyzes. The E-Prime Extension for Tobii passes on to Pro Lab:

A popular alternative is subscription-based multimodal platforms: a mandatory core module, with separately paid modules on top — including eye tracking — and eye trackers from various manufacturers. Pro Lab works differently: it is part of the Tobii system, and you can buy a perpetual license.
Prefer to spread the cost over time? Pro Lab is also available as a subscription — the choice is yours. We will give the terms of both options in our quote.

Ask about the Distributed Online edition* In the Distributed Online edition, design and recording take place online in Tobii Sticky. According to Tobii, screen-based eye trackers require the Full or Screen-Based edition, and glasses require Analyzer (or Full). Edition scope according to the Tobii Pro Lab page (as of 2026-10); we will confirm license details in our quote.
Eye tracking is often combined with other measurements: EEG (brain activity), ECG or fNIRS. Pro Lab records eye tracking data and — with a Shimmer sensor — the GSR signal (emotional arousal). Other signals are recorded by a separate system, e.g. EEG, in its own software. Pro Lab sends it event markers (TTL) — e.g. at the moment a stimulus appears — so both recordings can later be aligned in time.
Pro Lab records the stimulus, gaze, pupil and GSR. At the moment a stimulus is shown, it sends a TTL marker to the EEG system, which records it alongside its own signal. The two recordings are combined in the analysis after the study — using the markers.
You record EEG, ECG or fNIRS in the software of the respective system — Pro Lab supplies the event markers.

Not always. Tobii screen-based eye trackers come with the free Tobii Pro SDK — it is enough if you program experiments yourself (e.g. in Python or MATLAB). Pro Lab is for teams that want to design, record and analyze studies without programming, with ready-made visualizations and metrics.
For research at a monitor — Screen-Based; for analyzing recordings from glasses — Analyzer; for a lab with a screen-based eye tracker and glasses, or for working with E-Prime — Full; for remote research via participants’ webcams — Distributed Online. The simplest way is to describe your study to us — we will match the edition.
Tobii offers both models. A perpetual license is a one-time purchase; a subscription spreads the cost over time. We will give the terms of both options, including updates, in our quote.
Yes — 30 days of the full Pro Lab edition with seven demo projects, recorded data and self-study exercises. We can also demonstrate the software live with Tobii hardware.
No. Pro Lab requires Windows 11 (64-bit) Professional or Enterprise and is not supported in virtual machines. On macOS and Linux, Tobii screen-based eye trackers are used via the Tobii Pro SDK.
The manufacturer lists older models (including Pro Nano, Pro Glasses 2, Pro X3-120, Pro TX300) as discontinued; Pro Nano and Pro Glasses 2 are not supported since version 25.19. If you have older hardware, tell us the model — we will check which Pro Lab version it works with.
GSR — yes: Pro Lab records it directly from the Shimmer3R sensor, together with the eye tracking data. EEG, ECG or fNIRS is recorded by a separate system in its own software; Pro Lab sends it event markers (TTL, e.g. via the Brain Products TriggerBox), and the data is aligned after the study. We configure such workstations at Interlab.
