Tobii Pro Nano
A screen-based eye tracker which captures gaze data at 60 Hz and is designed for fixation-based studies. This easy-to-use, robust research system is an ideal entry point for those considering beginning eye tracking research or those wishing to take their eye tracking research out of the lab environment.
Features
Enter the world of eye tracking research
Tobii Pro Nano is our smallest, most lightweight research-grade eye tracker, featuring the latest technology from Tobii Pro. It’s ideal for those who are new to eye tracking research, or for researchers wanting to take their studies outside the lab environment.
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 and build your knowledge on how to use eye tracking as a research method to analyze visual attention and gain valuable insights.
The system shows exactly where people are looking, and with a sampling rate of 60 Hz it’s designed for fixation-based research.
Fully-portable for research in the field
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 schools, hospitals and public places – wherever your participants are.
The ability to track virtually anyone, as well as simple setup and configuration, makes the system perfect for running studies efficiently outside the lab.

Tobii Pro Nano:
-
- attaches easily with supplied mounting plates on various screens.
- offers fully embedded processing of eye tracking data.
- connects via a USB port directly to your computer.
- calibrates participants quickly.
Teach students how to use eye tracking
Recruiting test subjects is an obstacle all researchers face. Certain test populations are more difficult to recruit and test in the lab and some individuals might even feel uncomfortable in this environment.
The size and shape of Tobii Pro Fusion allow you to put together a compact mobile lab which enables you to take your data collection to where your subjects are available and feel more comfortable, without compromising on data quality and granularity.
The patented Tobii eye tracking algorithms and robust subject calibration ensures that the eye tacker produces reliable data across different indoor environments.
Versatile for many types of studies
Pro Nano works with Tobii Pro Lab, a versatile Windows software platform designed to meet the highest demands of different research scenarios with exact timing accuracy. This software offers an efficient workflow, making it easy to design experiments, record and analyze data, and obtain eye tracking visualizations.
By integrating the Shimmer3 GSR+ Unit, Pro Lab supports combining eye tracking and GSR data, throughout the entire workflow. The ability to send TTL signals on stimulus onset from Pro Lab allows precise synchronization of gaze information with data from other sources such as EEG or ECG.
Mac OS users can now use Pro Nano in their research through Tobii Pro SDK, that offers a comprehensive toolkit for researchers or partners who wish to develop their own applications to use with Pro Nano or other screen-based eye trackers from Tobii Pro.
Pro Nano provides high-quality data for studies run on Windows PC and Mac laptops with screen sizes up to 19 inches. The system can also be used to study real-world stimuli, such as physical objects or people, which enhances your research opportunities.
Track almost anyone with quality data
The system’s very high accuracy and proven vast tracking capabilities in many conditions offers a reliable solution for large population field tests and teaching contexts.
Feature include:
- Extremely robust tracking capabilities, regardless of ethnicity or corrective lenses
- Tolerance for head movements and varied lighting conditions
- Eyes are detected instantly with minimal data loss during blinks or when participants look away
- Pupil data is captured at the same sampling rate as the gaze data
Research graded eye tracker
Pro Nano’s high data quality has been confirmed through extensive testing. We use well-documented methods from systematic variations of environmental conditions to a general assessment of the eye tracker’s performance within a large sample of individuals. This makes the system suitable for publishing research reports.
Multiple product certifications ensure that quality and user safety requirements are met.
Components
Eye tracker unit
The eye tracker measures only 170 mm (6.7”) in length and weighs 59 g (2.1 oz.). It attaches to screens up to 24″ (16:9) with supplied adhesive mounting brackets for monitors, laptops and tablets.
Mounting solutions for use with mobile devices, as well as brackets for larger projections or real-world objects are offered as accessories.
