The tracker maintains dependable eye tracking performance across various eye features and participant populations because to its dual-camera architecture, adjustable illumination, and unique 3D eye model.

Compatibility with Prescription Glasses & Contact Lenses

Tobii Pro Spectrum is designed to support participants who wear:

• Prescription glasses

• Contact lenses

Its:

• Dual-camera architecture

• Adaptive illumination

• Patented 3D eye model

help maintain reliable eye tracking performance across different eye characteristics and participant populations.

Adaptive Illumination

The system automatically selects between:

• Bright-pupil illumination mode

• Dark-pupil illumination mode

This helps optimize eye image quality under varying participant characteristics and environmental conditions.

The adaptive approach improves robustness when tracking participants with:

• Different iris colors

• Different pupil sizes

• Corrective eyewear

Combined with Tobii's binocular tracking technology, it enables consistent gaze estimation while minimizing participant burden during setup.

Factors That May Affect Tracking Quality

As with any infrared eye tracker, certain conditions may reduce tracking quality, including:

• Highly reflective lenses

• Mirrored lenses

Researchers are therefore encouraged to:

• Verify calibration quality before beginning data collection

Reliable Performance Across Diverse Populations

Under normal conditions, Tobii Pro Spectrum provides reliable tracking for the vast majority of participants.

This makes the system suitable for:

• Clinical studies

• Developmental research

• Experiments involving diverse participant populations

Summary

The Tobii Pro Spectrum is made to assist users who wear contact lenses or prescription glasses. Researchers are encouraged to confirm calibration quality when working with highly reflective or mirrored lenses, but its dual-camera architecture, adaptive bright-pupil and dark-pupil illumination, patented 3D eye model, and binocular tracking technology help maintain dependable eye tracking performance across diverse participant populations.
