The exclusion zones cover %38 of the total touchpad area.
total touchpad size = 105mm x 64mm
left exclusion zone = 14mm x 64mm
right exclusion zone = 14mm x 64mm
bottom exclusion zone = 77mm x 10mm
The bottom exclusion zone allows taps but prevents horizontal motion if the
touch started in the zone.
I have a System76 Kudu3 laptop running Ubuntu 17.10. The touchpad has physical
buttons underneath the touch surface, not separate from it.
