Eye tracking setup: A step‑by‑step guide for reliable results

Eye tracking 101 series - #3

Setting up an eye tracker should feel straightforward — and with the right process, it is. Whether you're preparing a wearable device for real‑world research or configuring a screen‑based tracker in a lab, the foundation remains the same: A well‑planned setup leads to cleaner data, smoother sessions, and fewer surprises once participants arrive. 

In this guide, we walk through the essential steps for getting started with both
Tobii wearable and screen‑based eye tracking systems, along with practical tips our teams use every day when supporting researchers worldwide. 

1. Start with the basics: Define the study environment 

Before you unpack a single cable, take a moment to think about where your sessions will take place.

• Choose a space with stable lighting — no strong reflections or shifting sunlight. 

• Make sure your screen is free from fingerprints or smudges that can reflect infrared light. 

• Confirm that your participant can sit comfortably at the correct viewing distance.

• Scout the environment ahead of time. 

• Note the lighting, layout, and any movement or obstacles in the scene. 

• If you’re running fieldwork (stores, hospitals, offices), check for reflective surfaces, mirrors, or screens that might affect the scene camera. 

This early preparation is one of the simplest ways to avoid drift, poor calibration, or signal loss during real sessions. 

2. Prepare your equipment 

Screen-based systems 

Unbox → Connect → Position → Power up 

Most Tobii screen-based trackers are plug‑and‑play, but taking a few minutes to align everything correctly will save you time later. 

• Mount or position the eye tracker according to the model’s guidelines. 

• Make sure the tracker is centered relative to the participant’s eyes. 

• Launch Tobii Pro Lab, verify that the system recognizes your device, and check the live eye feed. 

Wearable systems 

Unbox → Charge→ Clean → Pair 

Wearables require a slightly different approach: 

• Charge the recording unit fully. 

• Clean the lenses and scene camera. 

• Adjust the nose pads and temples so the glasses fit naturally on the participant’s face. 

• Pair the wearable with your recording device via Tobii Pro Glasses Controller App or check connectivity in the Tobii Glasses X App.
  
  Tip: Always carry a microfiber cloth, backup SD cards, and a few extra nose pads when running field studies. 

3. Position your participant correctly 

Regardless of the method, participant posture is a major factor in tracking quality. 

For screen‑based eye trackers

• Sit the participant at the recommended distance (typically 55–65 cm depending on the tracker). 

• Encourage a relaxed, natural posture. 

• Keep the chair still once calibration starts. 

If you’re using a laptop‑mounted Tobii eye tracker, ensure the participant isn’t reclining too far back, as steep angles can reduce accuracy.

Fit is everything. 

• Adjust the glasses so they sit as naturally as their own eyewear. 

• Make sure the scene camera has a clear view — no hair in front, no caps/sunglasses. 

• If participants wear prescription glasses, test comfort and tracking quality before starting utilizing the corrective lens accessory kit. 

When the glasses feel comfortable, people forget they’re wearing them, which results in more natural behavior. 

4. Run a calibration that works for your study 

Calibration is your quality gate. Consistent, clean calibration means your data will map correctly to the visual scene. 

Screen-based calibration 

Using Tobii Pro Lab: 

1. Select your calibration layout (typically 5‑ or 9‑point). 

2. Give the participant a simple instruction: “Follow the dot with your eyes.” 

3. After calibration, review the validation immediately. 

4. Recalibrate if accuracy or precision falls outside acceptable ranges. 

If you see excessive scatter or missing points, pause and readjust posture, lighting, or tracker position. 

Wearable calibration 

With Tobii Pro Glasses 3: 

1. Show the participant the calibration card at arm’s length. 

2. Have them focus on the center of the marker. 

3. Complete the calibration using the controller app or Tobii Pro Lab. 

4. Run a quick live preview to confirm tracking quality. 

In dynamic environments, it’s often worth recalibrating between sessions — it only takes a moment and ensures consistent data. 

With Tobii Glasses X : 

1. The system automatically calibrates moments after putting the Glasses X onto the participant 

2. Check in the Tobii Glasses X Application that a gaze cursor is visible. 

5. Test your setup before the first real participant 

Never run your first session with a participant you’re paying for or scheduling formally. 

Do a dry run. 

• Record a full session with a colleague. 

• Play back the data with your AOIs, timeline, and visualizations. 

• Check that calibration holds, gaze maps correctly, and all stimuli appear as expected. 

For wearables, walk the entire route you’ll ask participants to take — lighting and reflections can shift throughout the day. 

This one step often prevents the most common study failures. 

6. Run, review, repeat 

Once your setup is live:

• Start each session with a quick tracking check 

• Keep the participant comfortable 

• After the session, immediately review a short segment of the data 

This helps catch issues early — especially in fieldwork or multi‑day studies. 

If anything looks off, adjust for the next session instead of discovering the problem after all data has been collected. 

Final thoughts 

A solid setup doesn’t just make your research smoother — it ensures your insights are truly grounded in human behavior. Whether you’re preparing a controlled experiment with screen-based eye trackers or capturing natural, real‑world moments with wearables, following a consistent setup routine will give you cleaner data, clearer visuals, and more confident conclusions.
