Text is entered into an electronic communications device by means of a keypad having a number of keys, each key representing a plurality of letters and / or character sequences, entered text is displayed on a display on the device. Possible character sequences corresponding to an activated key sequence are generated. These are compared with a stored vocabulary comprising character sequences representing words as well as word stems occurring in a given language. Those stored character sequences that match the possible character sequences are pre-selected and a number of these are presented in a separate graphical object arranged predominantly on the display.

There is disclosed an enhanced text entry system which uses word-level analysis to automatically correct inaccuracies in user keystroke entries on reduced keyboards such as those implemented on a touch-sensitive panel or display screen, or on mechanical keyboard systems. A method and system are defined which determine one or more alternate textual interpretations of each sequence of inputs detected within a designated auto-correcting keyboard region. The actual contact locations for the keystrokes may occur outside the boundaries of the specific keyboard key regions associated with the actual characters of the word interpretations proposed or offered for selection, where the distance from each contact location to each corresponding intended character may in general increase with the expected frequency of the intended word in the language or in a particular context. Likewise, in a mechanical keyboard system, the keys actuated may differ from the keys actually associated with the letters of the word interpretations. Each such sequence corresponds to a complete word, and the user can easily select the intended word from among the generated interpretations. Additionally, when the system cannot identify a sufficient number of likely word interpretation candidates of the same length as the input sequence, candidates are identified whose initial letters correspond to a likely interpretation of the input sequence. The approach utilizes the information contained in the entire sequence of keystrokes corresponding to a word in order to determine the user's likely intention for each character of the sequence. The system also accommodates punctuation characters such as hyphens or apostrophes that are commonly embedded in words such as hyphenated compounds and contractions in English, and characters with special diacritics such as are commonly found in various European languages, e.g., diacritic accent. Special functions may be applied depending on where the user touches the intended string in a displayed word selection list. Once the user selects the desired string, it is automatically “accepted” for output and the next input detected starts a new input sequence corresponding to the entry of a next word.

A data entry system comprising a group of data symbols comprising at least one of alphabetical symbols, numeric symbols, and commands (128–136), divided into subgroups. Each subgroup is associated with at least a portion of the user's finger (102–120). The system also comprises a keypad (126) defining a plurality of keys, wherein each key contains at least one of the symbols. At least one finger recognition system (100) is configured to recognize the portion of the finger when it touches a key, and to select the subgroup symbols associated with that portion of the finger interacting with that key.

In entering text into an electronic device with a keypad having a number of keys, each key represents a plurality of characters. A character is entered by the corresponding key and selected among the plurality of characters by pressing the key a number of times corresponding to the character. To each key is attached, in addition to the plurality of characters, a further, ambiguous character representing any one of the plurality of characters. A key sequence is activated such that an ambiguous character sequence comprising at least one ambiguous character is generated. Possible non-ambiguous character sequences corresponding to the ambiguous character sequence are generated and compared with a vocabulary stored in a memory and comprising character sequences representing words occurring in a given language. Those possible character sequences that match character sequences in the vocabulary are pre-selected. One of the pre-selected character sequences is selected and entered into the device.

Method with which users (1) enter instructions, in which said instructions are entered with sequences of voluntary movements of eye parts, the sequence required for entering a certain instruction being individual for each user.

Data entry and display apparatus and methods that provide greater efficiency in data processing devices. The apparatus comprises a keypad with a plurality of first keys and plurality of secondary keys, the first keys each having at least one primary alphanumeric symbol and at least one of the first keys having a secondary alphanumeric symbol associated therewith, the first key with the secondary symbol being operable to selectively display the secondary alphanumeric symbols in association with the second keys. The apparatus may further comprise a display, which may be embodied in a common touch screen user interface with the keypad. The methods comprise actuating one of the first keys on the keypad and displaying a set of secondary alphanumeric symbols in association with the secondary keys, and selecting the primary alphanumeric symbol associated with the first key or selecting one of the set of secondary alphanumeric symbols by actuating one of the second keys. Selection and actuation of appropriate combinations of first and second keys allows entry of any character string.
