Well it's not about just redefining the key input mapping, it's about the visual physical labeling on keys. There are (or were) some keyboards with small LCDs under each key on the market where you can dynamically remap the visual presentation on the keys themselves as well (or even show small images) without moving to a virtual keyboard. I've been using keyboard for many decades and I still occasionally look down and visually map out a key or fingering position. The visual mapping needs to be correct, I don't want to play a mental mapping game that 'q' should be 'z' or whatever.
