Apple was one of the first tech companies to design and sell a computer mouse with a housing that accepted gestures like pinch and zoom and scrolling without a scroll wheel. Since that time, their R&D team has filed for another patent relating to a keyboard that could understand in-air gestures. That particular idea apparently caught Microsoft's eye. Last week the US Patent Office published Microsoft's patent application for a gesture assisted keyboard. Their patent-pending invention reveals that Microsoft may use high-end technology to achieve in-air gestures over a keyboard or simplify some functionality by combining specific keyboard keys assigned to different gestures and quick hand gestures. In our cover graphic example, the user has pressed a specific keyboard key and by moving their finger over this key up or down, they're able to control webpage scrolling without the use of a notebook touchpad.
