When I wrote about virtual keyboards, I mentioned that the iPhone dynamically resizes the "touchable" area of each key based on the probability of that letter being the next letter in the word you're typing. Moritz Haarmann's Qwerted is a virtual keyboard which implements this feature for Android phones. Unlike the iPhone, Qwerted visibly resizes the actual key, which results in a rather striking effect:

I suspect that visibly changing the size of the keys may be more confusing than helpful. Moritz Haarmann is currently doing field tests, and I'll publish an update as test results become available. Regardless of whether it's a good idea, I think it looks pretty cool.
