It's not just your clumsy leg-kicks that Kinect will understand, with a newly discovered patent showing that it's actually capable of understanding American Sign Language, or ASL. Is this another way to input text to the game?
It could be, if you actually know ASL - it's estimated that anywhere up to two million people in the US know sign language. At the very least, leaning how to sign could help save you from forking out for a keyboard peripheral. [GoRumors via SlashGear]
