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.
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.

Report for Pro Nano
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:
Today’s marketing researchers need to move out of the lab to find answers to their questions and Tobii Pro Nano gives you the ability to combine the strengths of a lab with field studies.
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.

Hands-on learning is really effective, and the portability of Tobii Pro Nano lets me easily involve my students in the whole process of an eye tracking study from the theoretical knowledge to the practical use of this technology in their own experiments.
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:
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.
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 19" (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.
