US Patent 9075436 Motion-based interface control on computing device

A computer-implemented user interface method include displaying an image on a graphical user interface of a mobile computing device, receiving a first user input indicating an intent to perform a zooming operation on the graphical user interface, transitioning the mobile computing device into a zooming mode in response to the user input, sensing motion of the mobile computing device in one or more of a plurality of directions, correlating the sensed motion in one or more of a plurality of directions with either a zooming in or a zooming out zooming direction, and changing a zoom level of the display of the image on the graphical user interface to correspond to the correlated zooming direction.
