An iPhone patent is filed by Apple details motion control and a front facing insight on a future model of the iPhone.The patent is called “Variable Device Graphical User Interface” and it outlines a number of new features intended for Apple’s new product.

The absence of an iChat application from the iPhone has always seemed odd, and it may well be that the inclusion of a front-facing iSight camera will be accompanied by an iChat app developed by Apple.The front facing camera (known as an iSight camera on Mac computers) lends support to recent rumours that outlined video conferencing as a major iPhone feature.
Although they are technically close enough to the current generation of iPhone, it is not clear whether these features are planned for the next iPhone which is rumored to be appearing in June 2009.
The iPhone already has limited motion controls in forms of a shake-to-shuffle feature. Although a Nintendo Wii-like experience may be off the mark, the motion control feature is also interesting. Apple’s patent describes how this could be extended to detect when you are walking with the iPhone. The interface will then expand to display larger items than normal, making them easier to select while you move around.
