7. 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
 Cleans and decreases
the amount of data
 Raw Data Filter
 Tobii Fixation Filter
 ClearView Fixation
Filter
14

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.
15

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
