Method and system of managing a user interface of a communication device

A method and a system of managing a user interface of a mobile wireless communications device for use in data devices, comprises the step of determining a relative location of the user and the device. The determination is performed on the basis of the signals from an array (208) of sensors (210). A control unit (204) determines this relative location. Knowing the relative location of the user, the control unit (204) can automatically change the orientation of the user interface. If the user interface (202) is a display screen, its content can be rotated to a position that ensures the user the best possible view. If the user interface (202) is a keypad or a touch screen, functions of each key can be redefined to ensure the best possible position for use. Knowing the distance between the user and the user interface, the control unit (204) can change the size of the most important information window on the display screen. The change is made automatically as the distance between the user and the user interface changes. The importance of information windows is ranked, and the ranking is stored in memory (206).
