Eye tracking

For eye tracking we use an EyeLink 1000 binocular tracker from SR Research. The current installation runs at a maximum of 1000 Hz, tracking both eyes binocular.

The eye tracker is typically controlled via Neurobs Presentation,
Via Presentation you can access the eye tracker output in realtime.

The X, Y and pupil diameter of each eye is also output into the MEG system analog channels and sampled side by side with the MEG data. The calibration space of the Eye-tracker is 1920x1080, with 0,0 in the top left corner.

The Eye tracker settings are aligned to the projector, so that the projector ini-file uses the pixel space (1920x1080), standard visual size (72x44 cm) and distance (100 cm) of the projector.
