Invisible button on iPhones? Oh Apple, what next? Buttons in thin air??

One would think Steve Job's death October,2011 meant the end of innovations for Apple, but that doesn't seem to be the case here as Apple just acquired a patent for inclusion of an invisible button in iPhones.

Disappearing button?

According to the patent, iPhones and other patented technologies would include this button which would be hidden by default and would only appear on activation by heat, sound or motion by fingers. This buttons would be made by the same material as the casing and would only appear after activation with light showing up from selectively tiny holes.

I rather would see this as aesthetically pleasing and some sort of magic trick for my siblings..lol.. *oyibo thing*
