The image (which is large) shows a handheld like device that responds to a persons voice commands. I see no reason why the software couldn't be used on Wii u for similar actions to the Kinect's voice commands, as the gamepad has a built in microphone.
The patent was filed in 2005, So that means that Nite do could just use it on the Wii u for voice commands.
