I detest touch screen interfaces for most things. My character error rate on texting is typically around 20%, using a modern mobile phone. I am seeing much more touch screen interface stuff on complex test equipment like spectrum analysers. One of the problems I first encountered was pointing out some interesting feature on the screen, and the stupid instrument responded to my touch and Did Something. So I had to reset to defaults and start again.
I have quickly glossed the comments, and I am surprised that I could not find a reference to a soft key interface. This is where the interface has a graphical screen surrounded by anonymous physical buttons. The functions of the hardware keys can vary depending on what task or mode the user has selected, and adjacent labels on the screen tell the user what the current function of each button is. I really like this system for controlling complex test equipment. It is often augmented by a numeric keypad and spin wheel.
I will grant that this interface is more expensive to implement than a touch screen, but for complex RF test kit and military stuff, it would appear to be vastly superior. The screen and buttons can be made very rugged. And it still has the advantage that button names/functions are programmable in firmware, and not hard wired.
