Apple computers, meet the Wiimote. In a customary bit of patent digging, Apple Insider happened upon plans for a "wireless remote wand," which would give users motion sensing controls over the Apple TV, a la Nintendo's popular console.

The proposed device utilizes an accelerometer or gyroscope to control the system with three-dimensional movements. Also:

The wand may include an optical component for capturing images of the infrared modules, and may calculate its orientation and distance from the modules based on the captured images. In some embodiments, the electronic device may direct the infrared modules to identify the position of an infrared emitter incorporated on the wand, and may calculate the absolute position of the wand relative to the infrared modules.

Apple recently introduced a new version of the Apple TV, so I'm guessing we'll have to wait at least a year for something like this to come to fruition--if in fact it ever does.
