Patent ID: 7106314

Claim:
A mobile device having a user interface operable by a user, comprising: a sensor having one degree of freedom operable in a first direction and operable in a second direction opposite to the first direction to generate a sensor signal; a display screen having a first dimension and a second dimension showing a graphical user interface object to be actuated along a first actuated axis in opposite directions corresponding to the first dimension and along a second actuated axis in opposite directions corresponding to the second dimension; a processor coupled to the sensor to receive the sensor signal and coupled to the screen and configured to select a selected actuated axis and to actuate the graphical user interface object along the selected actuated axis in opposite directions and for adapting the sensor signal to actuate the graphical user interface object along both actuated axes in opposite directions along both actuated axes; wherein the graphical user interface object is actuated along the selected actuated axis in proportion to the sensor signal when the sensor is operated repeatedly in one direction, and wherein the selected actuated axis changes to the other actuated axis when the sensor is operated temporarily in the opposite direction.
