The patent office issued U.S. patents in these days that Apple could give us a clue as will the next generation of Magic Mouse. The document describes 3 new sensors and a 3-axis gyroscope for the accessory is capable of detecting balance sheet, the inclination and the deviation of the fitting.

This means that the user could tilt the mouse to do side to produce a horizontal displacement, vertical displacement or to tilt a chart. Additionally, the mouse described would have a completely convex lower surface displacements that are simpler.

Just remember that many of the technologies that Apple patented, never fail to occur, so it is better not fool yourself.
