Fully portable for research in the field

Tobii Pro Nano is designed to use with smaller screens, providing a compact, fully-portable research solution. Present your stimuli on a Windows or a Mac laptop for data collection in authentic research environments. Bring your portable lab to your participants.



Track almost anyone with quality data 

The system's high accuracy and proven vast tracking capabilities in many conditions offers a reliable solution for large population field tests and teaching contexts.

  • Sampling rate of 60 Hz designed for fixation-based research

  • Offers fully embedded processing of eye tracking data

  • Connects via a USB port directly to your computer

  • Calibrates participants quickly

  • Demonstrates robust tracking regardless of ethnicity or age

  • Tolerance for head movements and varied lighting conditions

  • Minimal data loss during blinks or when participants look away

  • Pupil data is captured at the same sampling rate as the gaze data

Assessment of changes in gaze patterns during training in point-of-care ultrasound

Using Tobii Pro Nano, Chan and colleagues (2022) measured the incremental learning after an ultrasound course. Two groups of first-year medicine residents interpreted ultrasound videos while their eye movements were recorded. After the first assessment, only the intervention group completed an introductory ultrasound course.

Maternal postpartum depression impacts infants’ joint attention differentially across cultures

Astor and colleagues (2022) assessed whether the negative association between maternal postpartum depression and infant development of joint attention is the same across western and non-western cultures. Researchers used Tobii Pro Nano to record the eye movements of Bhutanese infants and compared them to Swedish infants performing the same task.

How does wearing a facecover influence the eye movement pattern in times of COVID-19?

Frank and colleagues (2021) studied the effect on visual behavior when looking at someone wearing a face mask and how that affects the identification of facial features. Tobii Pro Nano was used to record eye movements. The results revealed that the sequence of focusing on facial regions — mouth, nose, and eyes — was not altered by the presence of a face mask.
