Yes - touch screens are great for cognitive.
Remember though - The current provisions do not in any way prevent the use
of touchscreens.
Kind of like keyboard and mouse. You don't say "no mouse" just "not only
by mouse".
Our current provision just says you should be able to do the touchscreen
activities from physical controls as well.
