AOI overall stats CSV


The "AOI overall stats" 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_count - for how many participants the eye-tracking data was collected for this item,
  • aoi_id - UUID,
  • aoi_name - the name that you give to an AOI while saving it,
  • aoi_size_ratio - 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_fixation_total_count - number of fixations within this area,
  • aoi_fixation_ratio_percents - how many of all the participants looked at the given area,
  • aoi_fixation average_time_ms - the time that the average fixation lasted for (in milliseconds),
  • aoi_fixation_average_total_time_spent_ms - the amount of time that participants spent looking at this area (in milliseconds),
  • aoi_fixation_ttff_ms - the amount of time that it takes participants (on average) to look at this area (in milliseconds),
  • 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.
