- Use the same name for every trial with the same participant. The log files will have the trial condition appended, no files will be overwritten.
- Once the trial is over close the application.
Files are logged to the available local user storage. On a windows machine this is often %APPDATA%\..\LocalLow\DefaultCompany\Attention Study

The log files are split in two, a file labelled _ACTIONS and a file labelled _GAZE, these files describe events such as button presses and the user's head movements respectively.
The _ACTION file will contain a csv list of events. Types are listed below, note that every line finishes with the current millisecond count since the application started.
