I have used touch screens with linux. Some do work via mouse input. however
it would be good to verify that this particular version does work that way...

If we're planning on having people use their fingers, be aware that
buttons/controls must be 3-4 times ( linear dimension) the size they
must be for typical mouse usage. Additionally certain widgets which
require dragging ( scroll bars for example ) do not work particularly
well
