I notice my laptop touch pad doesn’t work if my hand is wet.
I wonder if these guys verified that their touch screens still work if the user’s hands are wet, bloody, covered in grease, or any of a number of conditions likely to be encountered in a combat situation.
When working with toxic substances such as gasoline or oil, I wear disposable nitrile gloves. Touch screens on iphones or ipads are completely useless for when wearing them. This is especially bad when you need to enter data or even answer a phone call.
