The patent for Microsoft's motion-sensing camera Kinect suggested that the device could understand American Sign Language. Well, it can't. At least, the version going on sale in November can't.
Responding to the claims made in the patent, Microsoft has told Kotaku "We are excited about the potential of Kinect and its potential to impact gaming and entertainment. Microsoft files lots of patent applications to protect our intellectual property, not all of which are brought to market right away. Kinect that is shipping this holiday will not support sign language."
The original Kinect had a much higher resolution (over twice that of the final model's 320x240), and as such, was able to not only recognise the limbs of a player as the current model version can, but their fingers as well (which the current version can't). And when the hardware could recognise fingers, it would have been able to read sign language.
