This process is conducted by applying a fixation filter to the data Fixation filters are responsible for how fixation data such as fixation count duration and location is calculated This data in turn affects how gaze plots heat maps clusters and eye tracking metrics are inferred Fixation identification is mostly a mathematical and statistical process that attempts to describe how the eye moves Despite the accuracy and flexibility of some of the algorithms the limiting factor is that there is no precise definition for the start and end of a fixation and thus the identification process still remains partly subjective Therefore the best identification validation process is still to perform a test where you compare the fixation filter data with an observer s subjective impression on the position and duration of the fixations If you do not have any particular requirements in your study regarding how fixations should be defined use Tobii Studio s default fixation filters setting Tobii Studio uses two types of fixation filters to group the raw data into fixations Tobii Fixation Filter and ClearView Fixation Filter The basic idea behind these algorithms is that if we know the eye tracker sample rate and measure the distance between neighboring gaze data points we can calculate changes in the eye movement velocity for all eye movement samples During this process the raw data points are assigned to the same fixation if the velocity remains
