Eye trackers can work online, allowing researchers to track individuals' eye movements remotely. This is done through webcams and online eye tracking software platforms. Some popular platforms include Tobii Pro Lab, RealEye.io, and GazeFlow. In addition, you can enrol international participants in your study. Ensure the eye-tracking software works with foreign webcams and participants have a stable internet connection.

Thank you Hsin-Yuan Chen! I am wondering if conducting eye tracking on-line is common? and will the data be as accurate as doing it in lab? should I notice any specific requirements in case I do it on-line?

Online eye-tracking is growing, but it's not as reliable as doing it in a lab. Webcams and home lighting can make the data less accurate. Even with careful setup, you might not get results as good as in a lab due to different home environments.

I appreciate your reply! It was helpful.
