Abstract

A manual input navigation device and a sensor are utilized to manipulate graphical elements in a mobile device graphical user interface. The manual input navigation device generates an input navigation signal for altering a relative position of the graphical element in the graphical user interface, and the sensor measures a current tilt angle of the mobile device. Upon the generation of the input navigation signal, the current tilt angle is stored as a reference tilt angle. The relative position of the graphical element is altered based on the difference between the current tilt angle and the reference tilt angle.
