On the last patent day of 2009, the US Patent & Trademark Office published an important continuation patent from Apple that reveals one of the next chapters for Apple TV's remote. Firstly, the remote will implement a new magnetic compass within the remote's casing that will actually float in liquid so as to maintain its position relative to the gravity vector. This will provide the remote with incredible precision movement and fluidity. Secondly, with this new found precision, Apple hints of introducing a new illustration application to showcase this new remote's capabilities which would likely debut as iWork's fourth application. That in itself is great news. In theory, Apple's Keynote application would greatly benefit from such a new tool - in that it could provide the presenter with the ability to mark-up presentation graphics on screen live with this new 3D wand/remote.
