Scroll wheel on hinge

A wireless communication device comprising:

• a flip module having a front face with an internal display and a back face with an external display, wherein the internal display and external display are configured to present a user interface (UI);
• a base module having a keypad;
• a cylindrical rotatable assembly configured to enable the flip module to rotate in relation to the base module about a rotatable axis associated with the cylindrical rotatable assembly, the cylindrical rotatable assembly further comprising,
• a touch sensitive component on the exterior of the cylindrical assembly, wherein the touch sensitive component is configured to perform a scroll function that includes a scroll-up operation and a scroll-down operation;
• a flip-closed position, in which the flip module interfaces with the base module, wherein the UI displayed on the external display is controlled by the touch sensitive component on the cylindrical rotatable assembly;
• and
• a flip-open position, in which the flip module is substantially separated from the base module and the keypad is accessible, wherein the UI displayed on the internal display is controlled by the touch sensitive component on the cylindrical rotatable assembly.

A hinge assembly for an electronic device that pivotally connects a flip module to a base module having a keypad, wherein the flip module has a front face with an internal display and a back face with an external display, the hinge assembly comprising:

• a rotatable assembly configured to enable the flip module to rotate in relation to the base module about a rotatable axis associated with the rotatable assembly, the rotatable assembly includes a touch sensitive component that receives a plurality of navigation instructions comprising,
• a scrolling means, on the assembly associated with the touch sensitive component, wherein the scrolling means performs a scroll function that includes a scroll-up operation and a scroll-down operation,
• a zooming means, on the assembly associated with the touch sensitive component, wherein the zooming means includes a zoom-in operation and a zoom-out operation,
• a panning means associated with the touch sensitive component, that includes a pan-left operation and a pan-right operation, and
• a selection means associated with the touch sensitive component, that includes acknowledging a selection associated with a user interface (UI);
• a flip-closed position, in which the flip module interfaces with the base module, wherein the UI displayed on the accessible external display is controlled by the touch sensitive component on the rotatable assembly;
• and
• a flip-open position, in which the flip module is substantially separated from the base module and the keypad is accessible, wherein the UI displayed on the internal display is controlled by the touch sensitive component on the rotatable assembly.
