Abstract: A device and method for its operation comprising a display and input device, a processor to receive character input maintain an input context of words and a dictionary comprising a plurality of word occurrence indicators for selection of candidate words that may follow context words. A word occurrence indicator is associated with a kth order combination of a context word and a candidate word that indicates the frequency by which a respective candidate word follows the corresponding context word by k words in a text corpus. The processor is able to select a list of candidate words where the context word of at least one kth order combination matches the kth last word of input context. A score is determined depending on an associated word occurrence indicator for at least one relevant kth order combination.

Abstract: The invention relates to a method and device incorporating an improved text input mechanism. The text input method comprising the steps determining a list of candidates for the present context, a candidate being a possible textual continuation of the present context and having a relevance score assigned; arranging the candidates in groups, each group having a group designator; displaying the group designators; prompting the user to select a group and receiving the user selection; displaying candidates of the selected group, the displayed candidates being arranged according to their respective scores; prompting the user to select a candidate and receiving the user selection; accepting the selected candidate as text input and updating the context.

Abstract: A device including a display screen for displaying m-words of data, a text entry device for entering data, a processor receiving data from the text entry device and causing it to be displayed on the display screen. Upon activation the processor initializes a precursor to a predefined value. The device further includes a non-volatile memory storing a dictionary containing a plurality of entries, each entry including an index, a candidate word, and a score. The processor selects a list of n-number of candidate words from the dictionary whose index matches the precursor, and causes m-number of candidate words from the list of candidate words to be displayed on the display screen. The processor causes the display to prompt the user to select one of the displayed candidate words or enter a desired word using the text entry device.
