Native english speakers could consider themselves lucky. They don't have a need for accents, don't know about umlauts, about the -symbol, about the chinese, arabic, korean alphabet, and so on. A few letters, a few numbers, a few special keys there you have your english keyboard. The Optimus keyboard is a design study that does more than that.

Instead of having the letters painted on the keyboard, the keys are little displays. I counted 132 keys, that makes 132 small displays. Obviously, this invention is not from an native english speaker.
