1. A handheld electronic device comprising:
- a processor;
a display panel in data communication with said processor;
a user-input assembly in data communication with said processor;
one or more motion-sensing devices in data communication with said processor for sensing movement of the handheld electronic device and outputting a motion signal indicative thereof, the one or more motion-sensing devices including an accelerometer;
at least one optical sensor in data communication with said processor;
a memory device coupled to said processor, said memory device including instructions to be executed, wherein said instructions, when executed by said processor, cause said processor to;
determine relative orientation changes of the handheld electronic device over time based at least in part on multiple sequential images captured by the at least one optical sensor at one or more time intervals;
correlate the relative orientation changes with force data measured by the accelerometer to generate measurements of orientation with respect to a horizontal plane and inertial acceleration in three dimensions; and
based at least in part on the measurements of orientation, control display of an object on said display panel as a function of motion of said handheld electronic device, said function interpreting motion along a first axis as a first function that affects the display of the object on said display panel, and said function interpreting motion about a second axis distinct from the first axis as a second function that affects the display of the object on said display panel, wherein the first function is different from the second function.

Abstract
A user interface suitable for use in cellular phones and personal digital assistants (PDAs), PC Tablets, as well as laptops, PCs, office equipment, medical equipment, or any other hand-held electronic device, that allows control of the image on the device display by tilting the device to either change the view in perspective, change the magnification, or both, concurrently, by moving the device. Thus, the tilt of the device controls the angle of view of the image, and moving the device perpendicular to the screen controls the magnification.

11. A method comprising:
-
determining, by a handheld electronic device, relative orientation changes of the handheld electronic device over time based at least in part on multiple sequential images captured by at least one optical sensor at one or more time intervals; correlating, by said handheld electronic device, the relative orientation changes with force data measured by an accelerometer to generate measurements of orientation with respect to a horizontal plane and inertial acceleration in three dimensions; and based at least in part on the measurements of orientation, controlling, by said handheld electronic device, display of an object on a display panel of the handheld electronic device as a function of motion of said handheld electronic device, said function interpreting motion along a first axis as a first function that affects the display of the object on said display panel, and said function interpreting motion about a second axis distinct from the first axis as a second function that affects the display of the object on said display panel, wherein the first function is different from the second function. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
