http://aroundthe.net Tried thumb typing on a 10 inch tablet? I'm sure you're like me and find the experience heavy and awkward. Snapkey's have tried to solve this by moving all of the letters to the side and grouping them into 4 keys.
This 4-key virtual keyboard, that we got a sneak peak at during MWC and was officially launched at CTIA. The way it works is that the letters of the alphabet are all placed on to just four blank keys on your tablet or phone. The Letters are divided into four groups based on their shapes. On one key are letters that have a multiple points on the bottom, such as A, R, and W. Letters containing circles, such as O, B, and P are on another key. Two keys are placed on each side of a tablet, clearing up the entire device screen for typing.
To spell a word, users single tap the keys with their thumbs. Snapkeys software guesses fairly accurately which word you're trying to spell, and for unique names, you can manually drag a key rather than tap to select a letter.
