LocalAppData returns Null on Linux

Here is the output when running on Ubuntu 18.10:

Also, within IntelliJ I can see the following:

It appears that this is stemming from here

LocalAppData is not present on Linux, unlike Windows. This SO answer gives a good solution, but I haven't tried it yet.

Unique Eye Position

To give more accessibility to this project we should find a way to access the position of both eye separatly, for people using eye-tracking with one eye.

For now this function is integrated in some Tobii software for windows, but not for Linux.

get the GazePosition

in some cases, i can't access to the GazePosition because the librairy is call 2 times at the same time, so we have a concurrency.

Problem with pom.xml

I hope you guys can help me. When I use the project in Netbeans it works and prints out the gaze position in a extra window when I run the TobiiDemo class. But when I click on clean and build, the jar in the target folder does nothing. The class by itself in another project without the gaze function works fine. Any idea how to fix that?

Creation of the MacOS Librairies

In order to be used with a MacOS device we need to generate the libraries compatible to MacOS and to add the corresponding load inside the Tobii.Java class (in the MacOS TODO section)

Not a issue but a question, and i also didnt knew where to put it

Hello, I am a master's research student at the University of Coimbra currently doing some researcher with Tobii 4c eye-tracker. I have a question regarding whether you needed any kind of license to obtain the coordinates of the gaze. I'm currently trying to play with it in MatLab but every type of data regarding gaze seems to be limited with Tobi Pro SDK. Did you use Tobii Pro SDK?

Thanks for your time

NullPointerException when executing a runnable jar of the project

Hello, I am using a runnable jar file in order to trigger the recording of the sensor. Until now, i had no problem but recently i got the following error

Tobii: Copying /lib/tobii/x64/tobii_stream_engine.dll into C:\Users\Kurit\AppData\Local/.tobiiStreamEngineForJava
java.lang.NullPointerException
at java.base/java.util.Objects.requireNonNull(Objects.java:208)
at java.base/java.nio.file.Files.copy(Files.java:3112)

at tobii.Tobii.loadIfNotLoaded(Tobii.java:33)
at tobii.Tobii.gazePosition(Tobii.java:19)
at tobii.TobiiDemo.main(TobiiDemo.java:38)

I understand that when running the runnable, the code is somehow not detecting the connected eye-tracker, I am not sure what I did to trigger this, but the device only seems to work when i start the java code from Eclipse, while the execution of the Jar file won't trigger the eye-tracker to start recording.

Thank you in advance for your help and time.
