The RightType Keyboard is a custom keyboard layout for tablet computers. The layout is designed to make it easier to type with one hand.
The layout is based on the standard Qwerty keyboard. The keys for the right hand stay in the same position. The order of the keys for the left hand is reversed, and then the rows are interleaved with the rows for the right hand.
With just a little practice it quickly becomes second nature to locate the keys from the left side of the Qwerty keyboard with the right hand.
