• string participant_device - type of device a participant used during the study (desktop / smartphone / tablet),

• int participant_quality_grade - participant's overall data quality grade. From 1 to 6, where 1 means "very low", up to 6 meaning "perfect".

• int participant_quality_grade_item - participant's data quality grade for this stimulus. From 1 to 6, where 1 means "very low", up to 6 meaning "perfect".

• int test_item_display_order - a number indicating the order in which the items were displayed,

• int exposure_number - (useful for Live Website and Website Mockup type of studies) indicates the time the participant saw an item, i.e., 1 means that the participant saw this item for the first time,

• string aoi_id - UUID,

• string aoi_name - name of the AOI,

• float fixation_point_x - the x coordinate of fixation expressed as a percentage of the displayed item size,

• float fixation_point_y - the y coordinate of fixation expressed as a percentage of the displayed item size,

• int fixation_starts_at_ms - when the fixation appeared (counting from the beginning of displaying the item),

• int fixation_ends_at_ms - when the fixation disappeared (counting from the beginning of displaying the item),

• int fixation_duration_ms - for how long lasted the fixation,

• int aoi_gaze_total_count

• int aoi_gaze_time_to_first_gaze_at_ms

• int aoi_gaze_total_time_spent_ms

• float aoi_gaze_participant_ratio_percents

• int aoi_visit_total_count

• int aoi_revisit_total_count

• int aoi_revisit_average_count

• int aoi_click_total_count

• int aoi_click_time_to_first_click_ms

• float aoi_k_coefficient

• string external_data_*- all the external variables assigned to the participant (if applicable),

• notes: RealEye version, fixation filter settings [gazepoint interpolation (Hz) - to improve calculations we interpolate the data to 60 Hz; gazepoint interpolation max gap (ms) - we interpolate data if the timestamp gap between two input values is not bigger than this value (50 ms); gaze velocity threshold; min. fixation duration (Ms); max. fixation duration (Ms); moving median range (Ms); saccade max duration (Ms)]; TestCriteria - data was downloaded for participants [age=min:max, isGenderMale={true/false}, isGenderFemale={true/false}, isGenderOther={true/false}, isGenderNotSpecified={true/false}, qualityMin={from1 to 6}, qualityMax={from 1 to 6}, tags={tag1},{tag2},..., keys=KEY{anykey}, isParticipantTypeRealEye={true/false}, isParticipantTypeNonRealEye={true/false}], timestamp of when the file was downloaded.
