Abstract: A housing assembly for an ISDN multimedia capable wireless interface device having a plurality of operating capabilities. The housing assembly comprises a main housing, a cover, hinge assembly for coupling the cover to the main housing. The hinge assembly enables the cover to pivot and articulate relative to the main housing to transform the housing assembly into a plurality of mechanical configurations via sensors responsive to the pivoting and articulating of the cover provided in the housing assembly. The cover includes an illuminated keyboard having a display for selectively providing pixel-based graphics and light. The keyboard is disposed over the display when the device is operating in one of a plurality of operational modes. Each keypad of the keyboard has an image viewing surface and coherent light pipe mechanism for conducting light generated by the display to the image viewing surface the keypad.
