1. A handheld computing device, comprising:
- first and second screens comprising first and second display panels, respectively, to receive input from and provide graphical output to a user;
a plurality of electronic components comprising a processor and memory, the plurality of electronic components generating an electromagnetic field during operation;
a hinge connected to the first and second screens, wherein the hinge moves between a closed position and an open position; and
at least one Hall-Effect sensor operable, at a selected time, to sense at least one of variations in and a strength of the electromagnetic field, wherein the processor is configured, based on the currently sensed at least one of variation in and strength of the electromagnetic field, to determine a relative position of the first and second screens.
