Here are some detials from the patent:

1) Ultrasound to determine absolute depth from an ultrasonic detector (i.e. the PSEye microphone array), and to determine distance between two controllers in your hands, and/or between multiple player controlers

2) An array of LEDs picked up by the PSEye camera to determine absolute X/Y position (with support from microphone array and ultrasound signals using triangulation), as well as information about the controller’s location relative to your body etc.

3) Accelerometer in the controller to determine xyz and rotational inertia

Some of the readers at neogaf or saying that this has been rumored for a while, maybe even before the Wii itself. Ok, Nintendo fans what do you think of this? I honestly think it looks like a giant PENIS!!
