Eye position panel
The Eye Position panel shows a representation of the eye position throughout the recording. The location of the centre of the pupils is shown in mm at the top of the graphic. This is measured relative to an axis from the centre of the screen and normal to the plane of the screen.
A variety of metrics are shown at the bottom of the graphic:
HPD: Horizontal Pupillary Distance in mm
VPD: Vertical Pupillary Distance in mm
Dist: Viewing distance in mm
