Still haven't caught on to typing on that little non-tactile keyboard on the iPhone's screen? This little tech, from the creator of the T9 system (dreaded by some, loved by others) being shown off at TC50, could be just the ticket. Swype is kind of like a gesture-based system, except that it uses the keyboard knowledge you already have -- just run a stylus (or your finger) around a qwerty-board, hitting all the letters in your word on the way, and the program will guess the word you were drawing. If you're looking for something similar that's already appeared on the iPhone, you might check out ShapeWriter's WritingPad, which we hope will be returning to the App Store soon (warning: loud video on page).
It's pretty wild -- his drawing "Mississippi" set off my "awesometer." Unfortunately, while the iPhone is given just a slight mention (can you name another touchscreen device that's used as widely?), it'd probably need a little tweaking. He's using a stylus (which on the iPhone is a no), and it'd be tough to draw with accuracy on a keyboard as small as the iPhone, even on the bigger horizontal version. Still, I like it, and Apple could always consider something like this for the iTablet, whenever they decide to release that. It'd be an easy way to overlay another typing method onto an already-working nontactile keyboard.
