# CSV file: Raw Gazes and Raw gazes denoised

Exporting raw eye-tracking test results and using them.

---

You may get all test results from any study as CSV file.

To get the CSV file, simply click the **"Save Results CSV" button** on the study's dashboard (see also: [Export AOI data](https://support.realeye.io/download-aoi-data-to-csv-file/?hsLang=en)).

 

CSV file contains the following fields:

- string **participant\_id** - UUID,
- string **participant\_external\_id** - UUID,
- int **participant\_age** - participant's age given at the end of the study; could be undefined if the participant did not provide this info,
- int **participant\_gender** - participant's gender given at the end of the study: 0 - female, 1 - male, 2 - other; could be undefined if the participant did not provide this info,
- string **participant\_display\_gender** - participant's gender given at the end of the study; could be undefined if the participant did not provide this info,
- string **participant\_tags** - tags assigned to the participant (added by study owner),
- int **participant\_quality\_grade** - participant's grade from 1 to 6 where:
- 1 = very low,
- 2 = low,
- 3 = average,
- 4 = good,
- 5 = very good,
- 6 = perfect;
- int **participant\_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;
- string **item\_id** - UUID,
- string **test\_id** - UUID,
- timestamp **test\_created\_at -** when a participant provided the result,
- int **test\_duration\_ms** - stimuli view time in ms (it may be shorter than defined in settings due to image mapping with clicks),
- int **test\_browser\_width\_px** - participant’s screen width in pixels,
- int **test\_browser\_height\_px** - participant’s screen height in pixels,
- int **test\_item\_display\_order** - a number indicating the order in which the items were displayed,
- int **exposure\_number** - (only applicable for [Website Mockup](https://realeye.user.com/knowledge-base/articles/73/update/144/%7B%%20kb_article_url%20187%20%%7D) studies) indicates the time the participant saw an item, i.e., 1 means that the participant saw this item for the first time,
- JSON ARRAY **test\_raw\_data** - gazeInfo\[\], an array of info about gaze as shown below:
- int **gazeInfo\[0\]** - gaze point position on the screen (X-axis pixels from top-left corner). NOTE: It could be less than 0 or more than test\_browser\_width. The participant could be looking out of the screen.
- int **gazeInfo\[1\]** - gaze point position on the screen (Y-axis pixels from top-left corner). NOTE: It could be less than 0 or more than test\_browser\_height. The participant could be looking out of the screen.
- int **gazeInfo\[2\]** - time in ms since the beginning of the test.
- float **gazeInfo\[3\]** - Y scroll offset in pixels (in case the participant was using the scroll).
- float **gazeInfo\[4\]** - X position of mouse cursor in pixels (from top-left corner).
- float **gazeInfo\[5\]** - Y position of mouse cursor in pixels (from top-left corner).
- boolean|undefined **gazeInfo\[6\]** - indicating if the participant has clicked at that time; if not clicked then this data is not included.

> NOTE:

> For the "Raw gazes denoised" CSV the eyes posiotions in this array are already calculated due to the noice reduction level set (not raw samples).

- string **external\_data\_debug** - all the external variables assigned to the participant (if applicable),
- **notes**:
- RealEye version,
- (for denoised data) [fixation filter](https://realeye.user.com/knowledge-base/articles/60/update/63/%7B%%20kb_article_url%2053%20%%7D) 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);
- participantQualityGradeItemMin=X - CSV file can be downloaded filtered by the item quality grade, where X is a value from 1 (very low) to 6 (perfect),
- timestamp of when the file was downloaded.

> NOTE:

> Please be aware that **test\_raw\_data** for every participant will most likely contain a different number of **gazeInfo**. That's because the gaze-tracking sampling rate varies depending on the webcam, participant's computer performance and subscribed plan.

From following data

```
660ea005-d031-4c20-914c-b94d13c94497,34,1,4f6b3515-71f4-4fa3-b9ca-4fdfc1dee4ad,0c81e7a0-360d-4183-8345-5dabbeddbd90,2019-07-09T10:34:12+00:00,20000,2048,1019
```

we can tell, for example, that participant's id was "660ea005-d031-4c20-914c-b94d13c94497", the age was "35", "male", the whole test took 20000 ms, the screen resolution was "2048 x 1019".

Now let's take a single gazeInfo

```
[933,47,365,0,1073,725]
```

This data tells us that the participant was looking around the "933 x 47" pixels of his screen, "365" ms, since the test item had been exposed. "0" means the image has not been scrolled. His/her mouse cursor was at the "1073 x 725" pixel of his screen. The participant has not clicked a mouse at that moment.
