A newly discovered Apple patent suggests Apple may be looking at ways to implement multi-touch interfaces without a touchscreen. MacRumors uncovered the application, which describes Kinect-like technology that would allow users to point and make gestures in the air above the keyboard, just as they would on a trackpad.

The patent application, entitled "Image Processing for Camera Based Motion Tracking," notes that the keyboard is still the preferred way of entering data into a computer.
