Interesting that they move to touchscreens. With all the Hacker News stuff that comes by every day I can easily say that 99.9% is not what I do in daily life. But building control rooms for large industrial installations is. And from my perspective we see very little requests for touchscreens. They have a place, for example on a machine in an environment were a keyboard would be in the way. But only if the operator would not be wearing gloves. Very specific applications.
For large modern control rooms users will have either a keyboard and/or a custom button panel next to the mouse/trackball. With the mouse/trackball being the primary input device to click on objects on the screen. In many cases they don't even type in values but click on buttons on the screen to ramp up or ramp down a process value. Then they don't need a keyboard.
One advantage of using touchscreens in that very specific application is that it makes it easier to build simulators.
Every nuclear power plant has its own, somewhat unique control room, and to train operators properly, you have to replicate all the panels that make up that room, and it is much easier with touchscreens.
