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.
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.
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.

0.10° RMS¹ in optimal conditions (using built-in filtering)
0.3°¹ in optimal conditions
Binocular eye tracking
Eye tracker latency
1 frame (immediate)
Blink recovery time
1 frame (immediate)
Gaze recovery time
Data sample output
Timestamp, Gaze origin, Gaze point, Pupil diameter

Tracker and client time synchronization
Integrated between the eye tracker time domain and the client computer time domain.
¹Tobii uses an extensive test method to measure and report performance and quality of data. Please download the test report for more detailed information.
Head movement tolerance
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.
Tracker setup options
Eye tracker mounted on a tripod, allows for even larger screens or physical objects to be tracked.
The Mobile Testing Accessory enables research or usability tests on a mobile device.

Teach students how to use eye tracking
Packages are available for equipping universities with portable eye tracking solutions to teach students how to use the technology in different fields. Our experts can help develop curriculums that demonstrate how it can be integrated as a tool to answer research questions and enhance commercial endeavors.
Versatile with other research tools
By integrating the Shimmer3 GSR+ Unit, Tobii Pro Lab supports combining eye tracking and GSR data, throughout the entire workflow. The ability to send TTL signals on stimulus onset from Tobii Pro Lab allows precise synchronization of gaze information with data from other sources such as EEG or ECG.
