Or just use old fashioned mechanical controls in a carefully designed
ergonomic layout and make the touch screen an alternative.

But a lot of software people are idiots.  MIL-SPEC for any ordnance
says that the safe-arm system must physically interrupt the
pyrotechnic chain.  So we have a rocket big enough to stop a falling
tank (literally--we were supposed to be dropping the tank out of an
airplane at something like 300 feet altitude).  I'm the parachute guy.
The rocket guy has a kid who's describing the control system.  He's
going to do the safe-arm entirely in software.  I'm the only one in
the room who has a problem with this.  My manager doesn't get it.  His
manager doesn't get it.  I finally got it across--"If this thing fires
inside the airplane, it tears the airplane apart and everybody dies.
Now, are _you_ willing to ride with it?"  His manager looked at him.
My manager looked at him.  He thought about it for a while and allowed
as to how he'd reconsider his design.
