The assumption is made that a study was done using the SMI EyeTracking glasses and the BeGaze software for postprocessing.
In order to use this algorithm make sure you have the following available somewhere on your local machine:
* The original video of the participant without the overlayed gaze point
* The raw data file as csv exported from the BeGaze software. Make sure that the following columns are included:
* The raw data file as csv exported from the BeGaze software only for the correspondent video. Make sure that the following columns are included:

* 'Point of Regard Binocular X [px]'
* 'Point of Regard Binocular Y [px]'

### 9. Post Processing
For the results, we need the following folder structure. Please proceed and create them:
|-- Evaluation
|-- postprocessing
|-- nameOfTheDevice_SLSD
|-- nameOfTheDevice_FLSD
If this is the first time you are using this repository, you need to define areas of interest of the device, in order to run the post processing.
$ python3 --device=device-name
