Re: Touchscreens have their place
Absolutely, various control schemes have their merits. Choose accordingly and then test, test, and test again.
A capacitive virtual big red button can only be activated by exposed flesh - an accidental knock with a clothed elbow won't activate it. In some circumstances this is a good thing (launch missile!), in others it isn't (machines such as table saw and lathes are all fitted with big red STOP buttons that stand proud like mushrooms, and can be easily pressed from a range of angles, and are often placed so they can be pressed by a knee as well as a hand)
