How to run the app

EyeTracker (Pupil-labs python software)

• open a terminal and execute $ pupil
• pupil is actually a bash alias. You can change it in the bashrc. If you want to try a new version of pupil-labs' software, you have to modify the alias or create a new one
• after starting the pupil labs software, you have to start both eye cameras.
• for each eye will start an own window showing the stream of the eyecamera.
• you should change the area for captioning the eye. For that change to "ROI" and drag&drop the frame until it fits to the eye
• You should now start the Unity project to get the "surface". That is the area on the screen which is inside the markers. Those markers are identified by the pupil-labs software as which.
• after you started the unity project in fullscreen you can use the function to "detect the surface", while wearing the eyetracker and looking at the screen.
• Afterwards start the "udp server" plugin in pupil-labs and it should be up and running.

General -> Dection and Mapping Mode: 3D SurfaceTracker -> 3D-Localization enabled

Troubleshoot

• if no data is received in the unity app, check the ip in the udp server plugin on the pupil-labs side and check the firewall on the pc with unity
