All of the touchscreen UIs I used when I was in the infantry actually were mostly pretty good. The contractors seem to have been told explicitly that people will be wearing gloves or using knuckles in generally poor operating conditions. The sensitivity always seemed just right and it was almost impossible to accidentally send an unintentional input unless you hit the wrong button thinking you were hitting another. For example using the Blue Force Tracker inside a gun truck at night on shitty roads wasn't nearly as bad as I thought it would be.
