CSV file: AOI click count



The "AOI click count" CSV contains the following fields:

  • study_id - UUID,
  • item_id - UUID,
  • item_filename - the name of your file, as it was named while adding to study,
  • tester_id - UUID,
  • tester_external_id - (UUID) in case if you provide one by connecting the study with an external tool, i.e. a survey,
  • tester_display_name - the name that a tester gives while asked about a name, gender and age at the end of the study (if you have chosen that option), i.e. "Anna, Female, 27",
  • tester_quality_grade - tester's grade from 1 to 6 where:
  • 1 = very low,
  • 2 = low,
  • 3 = average,
  • 4 = good,
  • 5 = very good,
  • 6 = perfect;
  • tester_quality_grade_item - item's grade from 1 to 6 where:
  • 1 = very low,
  • 2 = low,
  • 3 = average,
  • 4 = good,
  • 5 = very good,
  • 6 = perfect;
  • test_item_display_order - a number indicating the order in which the items were displayed,
  • aoi_id - UUID,
  • aoi_name - the name that you give to an AOI while saving it,
  • aoi_size_percents - expressed as the percentage value relative to the size of the entire image,
  • aoi_time_range_from_ms - the start time from which the values of the AOI were calculated (you can set this time with the orange slider under the heatmap),
  • aoi_time_range_to_ms - the end time to which the values of the AOI were calculated (you can set this time with the orange slider under the heatmap),
  • aoi_click_total_count - how many clicks each participant made within this AOI,
  • aoi_click_average_time_to_first_click_ms - TTFC (time to first click) within given AOI,
  • aoi_fixation_ttff_ms - TTFF (time to first fixation) within given AOI.
  • notes - this column contains:
  • 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);
  • noise reduction level.
