1. A method for controlling a display on a portable electronic device, the method comprising the computer-implemented acts of:
- detecting a motion of said portable electronic device relative to a fixed point, wherein said motion follows a preferential motion arc that is natural to eye and/or hand coordination of holder of said portable electronic device;
calculating a position of said portable electronic device based on said motion that is relative to said fixed point;
calculating and analyzing said motion; and
adjusting said display based on said motion and on said position, if said motion corresponds to a user command.

Abstract
The present invention addresses the above described problems by simplifying the assumptions on possible motions made by a user. This simplification process can take place by making an assumption that the motion of the device will travel along a certain preferential motion arc, which will be referred to herein as the “Javal arc.” Calculations of motions of the device can be made based on these Javal arcs. Additionally, the double integration of each accelerometer is now eliminated and the expensive accelerometers are replaced by two magnetic sensors.
