Cue Mario Construction?

Nintendo have recently filed a patent for touch screen rumble feedback. The patent reveals a tactile feature, wherein rumble feedback is applied through the touch screen consequent to the user’s interaction.

The patent confirms that the hardware to which the technology relates to consists of two screens, with one being a display screen and one a touch screen, although with no name mentioned, it’s impossible to tell if the feature would be for the DS2 or yet another iteration of the original DS.

Still, a patent application does not necessarily mean that the technology will come to see the light of day, although this one certainly seems more realistic than some of the other crazy ideas we've seen floating around.
