METHODS, SYSTEMS, AND COMPUTER PROGRAM PRODUCTS FOR OPERATING HANDHELD ELECTRONIC DEVICES INCLUDING MOVEABLE DISPLAYS AND RELATED DEVICES

摘要

In a method of operating a handheld electronic device including a housing having a fixed display on a surface thereof and a moveable display that is configured slide along the surface to variably overlap portions of the fixed display, a signal is received from a position sensor adjacent the surface of the housing. A relative position of the moveable display with respect to the fixed display is determined in response to the signal from the position sensor. An image displayed on the moveable display and/or the fixed display is selectively manipulated according to the determined relative position of the moveable display to the fixed display. Related devices are also discussed.
