Abstract: A mobile telephone has a display (240) and a rotator input device (250) comprising a rotatable element and capable of generating commands for browsing and selecting objects on the display. It also has a wireless telecommunication interface to a mobile telecommunications network. A processing device is coupled to the display, the rotator input device and the wireless telecommunication interface. A text-handling software application is executable by the processing device. The processing device is configured, in a first operating mode, to provide first user input by way of the rotator input device (250), said first user input including a number sequence representative of a desired telephone number which is to be reached over the mobile telecommunications network, and to use said first user input when establishing a telephone call connection through the wireless telecommunication interface.

Abstract: A method of controlling a user interface of a portable communication apparatus (100) is disclosed. The user interface includes a display (240, 336) with a limited presentation area (352) and a manual input device (250, 338) with a rotary element (252). Graphical data to be presented is received and represents a required presentation area (500) larger than said limited presentation area. A first sub area (510) of said required presentation area is presented on said display. A first user input is accepted through said manual input device as a rotator rotary movement of said rotary element, indicating a desired navigation direction within said required presentation area. A second user input is accepted through said manual input device as a rotary movement of said rotary element, indicating a desired navigation distance within said required presentation area in said desired navigation direction.

Abstract: A mobile communication apparatus comprises a processor means and an interface. The interface comprises a display and a input means, which comprises a rotating input means arranged to provide a angular movement signal in accordance with an angular movement of the rotating input means. The processor means is adapted to generate a selectable number of counts from said angular movement signal.

Abstract: A portable communication apparatus has a rotary input device adapted for use by an end-user to control the portable communication apparatus. The rotary input device comprises an element which is exchangeable by the end-user.

Abstract: A method of text entry in a mobile communication device includes highlighting a representation of a key on a display and scrolling through a predetermined sequence of representations of a plurality of keys and highlighting one of the representations. If the device is operating in a first mode, the method includes selecting the highlighted representation of a key, generating a key identifier sequence, and providing the key identifier sequence as input to a software application which associates each key identifier sequence with a set of words whose spellings correspond to the key identifier sequence and which presents on the display at least one word whose spelling corresponds to the input key identifier sequence. If the device is operating in a second mode, the method includes selecting a character of the set of characters associated with the highlighted representation of a key, and presenting the selected character on the display.
