All over the world there are people less fortunate than the rest of us who are using a computer, I refer to the one-handed users. Here is a keyboard concept that will help them use the PC easier. The keyboard is called Caracol and it was inspired from a snail and now the typing is faster thanks to the rotating keywheel. The rotary keyboard features a 5:1 gearbox that rotates very easy. Caracol includes QWERTY keyboard and also keys that allow the typing of three characters. This is a great solution for the one-handed and they can only hope that it enters into production soon.
