angle and, hence, suitable for being used with the Tobii X1 Light Eye Tracker. It might
be possible for some users to use larger displays than the ones given below, but that
will be at the user’s own risk of not being able to collect eye tracking data in the top
corners of the display.

The display sizes above are based on tests on subjects without vision aids such as
lenses or glasses in normal office lighting without any interfering light sources such
as windows or near infra red light-emitting lamps. For persons with glasses or lenses
or other characteristics that might interfere with trackability such as droopy eyelids or
extensive use of mascara or environment with interfering light sources, the trackability
in the top corners of the display might be lower than for the conditions tested here.
