Defining Areas of Interest (AOI) 6

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. 7

Time to First Fixation The time in seconds from when the stimulus was shown until the start of the first fixation within an AOI. Recordings/Participants vs AOIs The time to the first fixation for every AOI is displayed separately for every participant. AOI C: Statistics Time to first fixation: 10 sec Fixations, 1 person AOIs A B A C C Stimulus Recording 00:00:00 00:00:10 00:00:20 00:00:05 00:00:15 Images vs AOIs The average time to first fixation over all participants is displayed for every AOI.

Fixation Count The number of fixations within an AOI. Recordings/Participants vs AOIs The total number of fixations within an AOI is displayed separately for every participant. AOI C Fixation Count: 4 Statistics Sum Fixations, 1 person AOIs A B A C C Stimulus Recording 00:00:00 00:00:10 00:00:20 00:00:05 00:00:15 Images vs AOIs The average number of fixations within an AOI over all participants is displayed for the respective AOIs. AOI C Fixation Count: 4 Statistics Avg Person 1: B C A A B C C C Fixations Person 2: C B B B AC C C A AAB A Stimulus Recording 00:00:00 00:00:10 00:00:20 00:00:05 00:00:15 Observation length  The total time in seconds for every time a person has looked within an AOI, starting with a fixation within the AOI and ending with a fixation outside the AOI. 10

Observation Length The total time in seconds for every time a person has looked within an AOI, starting with a fixation within the AOI and ending with a fixation outside the AOI. Recordings/Participants vs AOIs The total length in seconds for every time a participant has looked within an AOI displayed separately for every participant. AOI A Observation length: 5,5 sec Statistics Sum Fixations, 1 person AOIs A B A C C Stimulus Recording 00:00:00 00:00:10 00:00:20 00:00:05 00:00:15 Images vs AOIs The average observation lengths for the different AOIs are displayed, including all participants. AOI A Observation length: 1,5 sec Statistics Avg Person 1: B C A A B C C C Fixations Person 2: C B B B AC C C A AAB A Stimulus Recording 00:00:00 00:00:10 00:00:20 00:00:05 00:00:15 Observation count  The number of visits and revisits to an AOI. 1 2 11

Observation Count The number of visits and revisits to an AOI. Recordings/Participants vs AOIs The total number of visits and revisits to and AOI is displayed for every participant separately. AOI A Observation Count: 2 Statistics Sum Fixations, 1 person AOIs A B A C C Stimulus Recording 00:00:00 00:00:10 00:00:05 00:00:15 Images vs AOIs The average number of visits and revisits to an AOI, including all participants, is displayed for the respective AOI. AOI A Observation Count: 2 Statistics Avg Person 1: B C A A B C C C Fixations Person 2: C B B B AC C C A AAB A Stimulus Recording 00:00:00 00:00:10 00:00:20 00:00:05 00:00:15 Fixations before  The number of fixations before the participant fixated within an AOI for the first time. 12

Fixations Before The number of fixations before the participant fixated within an AOI for the first time. Recordings/Participants vs AOIs The number of fixations before a participant fixated within an AOI for the first time is displayed for every participant separately. AOI B Fixations before: 2 Statistics Sum Fixations, 1 person AOIs A B A C C Stimulus Recording 00:00:00 00:00:10 00:00:20 00:00:05 00:00:15 Images vs AOIs The average number of fixations before the different participants fixated the first time within an AOI, displayed separately for every AOI. AOI B Fixations before: 1,5 Statistics Avg Person 1: B C A A B C C C Fixations Person 2: C B B B AC C C A AAB A Stimulus Recording 00:00:00 00:00:10 00:00:20 00:00:05 00:00:15 Participant %  The percentage of participants that have fixated at least once within an AOI. 13

Participant % The percentage of participants that have fixated at least once within an AOI. Only available as a total for all participants (Images vs AOIs). AOI C Participant %: 100% Statistics Avg Person 1: B C A A B C C C Fixations Person 2: C B B B AC C C A AAB A Stimulus Recording 00:00:00 00:00:10 00:00:20 00:00:05 00:00:15 Fixation Filters in Tobii Studio  Cleans and decreases the amount of data  Raw Data Filter  Tobii Fixation Filter  ClearView Fixation Filter 14

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

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  Exporting AOI data to SPSS/Excel/MathLab etc. 16
