Patent ID: 7395081

Claim:
An anparatus comprising: a display; a rotator input device comprising a rotatable element and capable of generating commands for browsing and selecting objects on said display; a wireless telecommunication interface to a mobile telecommunications network; a processing device coupled to said display, said rotator input device and said wireless telecommunication interface; a text-handling software application which is executable by said processing device; and a text prediction engine, wherein the processing device is configured, in a first operating mode, to provide first user input by way of said rotator input device, said first user input including a number sequence representative of a desired telephone number which is to be reached over said mobile telecommunications network, and to use said first user input when establishing a telephone call connection through said wireless telecommunication interface; wherein the processing device is configured, in a second operating mode, to provide second user input by way of said rotator input device, said second user input including a character sequence representative of a desired text, and to forward said second user input to said text-handling software application; wherein the processing device is configured, in said second operating mode, to provide said second user input by displaying characters on said display and receiving commands from said rotator input device for browsing said characters and for selecting, in successive order, individual characters that constitute said character sequence; and wherein the processing device is configured, in said second operating mode, to display on said display a group of predicted characters that are available for browsing and selecting by way of said rotator input device; wherein said text prediction engine is configured to decide said group of predicted characters in response to a recently made user input and in accordance with a predefined inference logic, and wherein said recently made user input is a partial word, and wherein said predefined inference logic involves matching said partial word with a database of known and/or common words to predict most likely words that said partial word is part of, and wherein said group of predicted characters, that is displayed on said display, is formed by a respective next character only, following said partial word, in respective ones of said predicted most likely words; wherein no numeric or alphanumeric character keyboard is involved in said first and second operating modes.
