A reduced keyboard apparatus and method for use with small-sized communications and computing devices. Input via the keyboard is performed using fingers or thumbs. The keyboard is characterized by having no discrete boundaries between the included character spaces. The direction and the destination area of a keystroke do not have to be accurate and may correspond to a plurality of included character spaces. Each of the possible characters is provided with a probability value, continuously redefined according to the specific keyboard area activated by the keystroke. The input of a word is defined by a sequence of keystrokes corresponding to the letters of the word. Subsequent to the completion of a keystroke sequence, the apparatus and method determine the identity of the word through a disambiguation process based on area density distribution. The apparatus and method enable fast, natural, and intuitive tapping on small keyboards having character areas much smaller than the user's fingers while at the same time provide highly efficient word determination.

A data entry system is provided using a virtual dynamic keypad having at least four keys, wherein to four of the keys at least substantially all of the letters of a language are distributively assigned and wherein the locations of the four letter keys relating to each other are dynamically defined during the entry of text. A text entry system is also provided using a virtual keypad having at least four keys wherein to four of its keys at least substantially all of the letters of a language are distributively assigned and wherein the locations of the four letter keys relating to each other are dynamically defined based on a calibrating procedure provided by the user. A data entry system is provided using a pointing device providing different pointing directions wherein each of the pointing directions duplicates a key of a predefined virtual keypad model wherein to at least some of its keys substantially all of the letters of a language are distributively assigned.

There is disclosed an enhanced text entry system which uses word-level analysis to correct inaccuracies automatically in user keystroke entries on reduced-size or virtual keyboards. 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 region. The actual interaction 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 interaction 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 virtual 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.

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.

A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device. If a field into which text is being entered is determined to be a special input field, a disambiguated result can be sought first from a predetermined data source prior to seeking results from other data sources on the device.

In embodiments of the present invention improved capabilities are described for a mobile environment speech processing facility. The present invention may provide for the entering of text into a software application resident on a mobile communication facility, where recorded speech may be presented by the user using the mobile communications facility's resident capture facility. Transmission of the recording may be provided through a wireless communication facility to a speech recognition facility, and may be accompanied by information related to the software application. Results may be generated utilizing the speech recognition facility that may be independent of structured grammar, and may be based at least in part on the information relating to the software application and the recording. The results may then be transmitted to the mobile communications facility, where they may be loaded into the software application.

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 handwritten information input apparatus includes: a tablet including a handwriting input region and a text input item region; a pencraft selection processing part for receiving a handwritten input that selects at least a part of the pencraft displayed in the handwriting input region, and confirming the selected pencraft; a pencraft recognizing part for recognizing the pencraft confirmed by the pencraft selection processing part; an item storing part for previously storing information on an input item to be displayed in the text input item region; an item selection processing part for generating an item list for allowing an operator to select which input item in the text input item region a recognition result is sent to, based on the information stored in the item storing part; and an item input part for sending the recognition result to the input item selected in the item list, whereby an input destination item for the recognition result of the pencraft input by handwriting can be designated easily, or it is not necessary to designate an input destination item.
