Tobii Pro Nano is our smallest, most lightweight research-grade eye tracker, featuring the latest technology from Tobii. It's ideal for those who are new to eye tracking research, or for researchers wanting to take their studies outside the lab environment.
Overview
Easy to use
The easy-to-use system lets you conduct quality eye tracking studies with minimal effort and investment. Run tests across a range of areas such as psychology or marketing research to gain valuable insights.
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.
Features
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.

The characteristics of the gaze data from an eye tracker are described in terms of accuracy and precision. For more details, take the Accuracy and precision course in Tobii Academy.
Eye tracking technique
Video-based pupil- and corneal reflection eye tracking with dark and bright pupil illumination modes.
One camera captures images of both eyes for accurate measurement of eye gaze and eye position in 3D space, as well as pupil diameter.

Head movement tolerance
Good
One-camera system, gives an accurate calculation of the data and a good level of precision. More sensitive for head movement than the dual camera systems.
Operating distance (mounted on screen)
45 cm to 85 cm (18'' to 33'') from the eye tracker
Freedom of head movement
(width x height)
Freedom of head movement at 65cm distance
35 cm x 30 cm (13.78" x 11.81")
Freedom of head movement at 80cm distance
45 cm x 45 cm (17.7" x 17.7")
Optimal screen size
Up to 24"
For large screens, the limiting parameter is the quality of the gaze accuracy at the upper corners of the screen when the user sits close to the screen.
