Finding the right eye tracker for your needs can be a difficult process. There are many things to consider, all depending on what you want to study, and how you want to study it. Below, we’ve put together a comprehensive listing of many of the variables that you’ll want to consider when investing in an eye tracking unit.

These ten eye trackers are some of the most commonly used in biosensor-based studies, and all can be easily integrated in iMotions with other biosensors.
