Statistics in Tobii Studio

There are two different ways of presenting the statistical data for the different Areas of Interests (AOI) in Tobii Studio: Results for the different individual participants

(recordings/participants vs AOIs) Averages over all participants (Images vs AOIs).

Time to first fixation

The time in seconds from when the stimulus was shown until the start of the first fixation within an AOI.

Fixation Filters in Tobii Studio

Raw Data Filter Tobii Fixation Filter ClearView Fixation

15

The Raw Data Filter

No fixation filter is applied to the gaze data but all data points are displayed in the visualizations, and used for analysis in the statistics tool. Note that this will require a lot of computer resources and the analysis will be very slow if a lot of data is recorded.

The Tobii Fixation Filter

Detects quick changes in the gaze point signal using sliding averaging. How distinct the changes need to be in order to divide fixations can be adjusted with a threshold radius.

Assumes the only eye motions present in the scanpath are fixations and jumps between fixations.

16

The ClearView fixation filter Defines the maximum distance between two points for them to be

considered belonging to the same fixation and the minimum time for which gaze needs to be within the radius to be considered a fixation

Recommended settings for different situations: Stimuli/Media with mostly pictures: Fixation radius 50 pixels and duration

200ms Stimuli/Media with mostly reading: Fixation radius 20 pixels and duration 40ms Stimuli/Media with mixed content: Fixation radius 30 pixels and duration 100ms
