A method and system are provided for using input events on an electronic device. The method includes detecting a first input event compatible with a first platform and determining a second input event representing the first input event, which is compatible with a second platform. The method may include determining a third input event representing the first input event, which is compatible with the second platform, and calling an input event handler compatible with the second platform to generate the second input event using the third input event.

A handheld electronic device 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 &#x3c;NEXT&#x3e; 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.

Systems, methods, and software can be used to disambiguate an input into a handheld electronic device. In some aspect, one computer-implemented method includes detecting an ambiguous input including one or more selections of one or more input keys; generating one or more prefix objects corresponding with the ambiguous input; generating an output set including at least some of the one or more prefix objects, wherein each of the at least some of the one or more prefix objects is associated with an identified corresponding word object; determining, using a processor, a quantity of prefix objects in the output set is fewer than a predetermined quantity, and, based on the determination, adding as an orphan prefix object to the output set an additional prefix object of the one or more of prefix objects for which a corresponding word object was not identified; and outputting the output set.

The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. During text entry, a user is able to delimit a language entry session, such as the entering of a word, by actuating a multiple-axis input device or another input device. The user can also reinitiate the language entry session by actuating a linguistic input member at a location abutting the delimited word.

A handheld electronic device is provided with a function of text disambiguation. The device detects an ambiguous input including a number of selections of a number of keys, and displays a plurality of outputs for a duration of time based on an elapsed time between the number of selections of the number of keys. Each of the plurality of outputs corresponds to the ambiguous input. At least one of the plurality of outputs is an orphan prefix corresponding to the ambiguous input.

A system, method and mobile device for initiating a voice call from the mobile device is provided. An expiration time is determined based on a time reference synchronized with a mobile call server. The mobile device transmits to the mobile call server a session initiation protocol (SIP) call initiation request including a destination number and the expiration time. A second call initiation request to a secondary contact number is initiated to establish the voice call to the destination number, when a response to the SIP call initiation request is not received from the mobile call server prior to the expiration time enabling reliable establishment of the voice call when the first attempt is unsuccessful. The mobile device does not have to wait on the mobile call server to determine a call failure and ensure that subsequent call initiation by the mobile device does not result in a call establishment collision with the mobile call server.

In view of the foregoing, an improved handheld electronic device includes a keypad in the form of a reduced QWERTY keyboard and is enabled with disambiguation software. As a user enters keystrokes, the device provides output in the form of a default output and a number of variants from which a user can choose. 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 when initiating an activity session on a word such as during editing, the display outputs variants of the entire word being edited, rather than providing as variants only those parts of a word that are being edited. The device also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. In certain predefined circumstances, 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 &#x3c;NEXT&#x3e; 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 an input field into which text is being entered is determined to be special, a disambiguated result can be sought from a predetermined data source prior to other data sources.

An improved mobile electronic device enables the inputting of text in one alphabet, Traditional Chinese in the present example, by transliteration of inputs in another alphabet, BoPoMoFo in the present example. Since some of the inputs can be ambiguous, transliteration of an ambiguous input is delayed until a detection of a finalization event, thus avoiding the outputting of unnecessary transliteration results, and thus advantageously avoiding a distraction to the user.

Mobile electronic device and associated method enabling transliteration of a text input

A method of disambiguating an input into a handheld electronic device storing a plurality of objects includes a plurality of word objects is described. The method may include detecting an ambiguous input, outputting a number of first character permutations of the ambiguous input that each correspond to one of the word objects, and determining that the first character permutations are fewer in quantity than a predetermined number. The method may further include outputting a number of second character permutations of the ambiguous input that each correspond to an artificial variant.

A method of controlling an electronic device that has a touch-sensitive display includes detecting a touch at an area associated with a character displayed on the touch-sensitive display, adding the character to a character string, identifying, from stored data, objects that at least partially match the character string, determining a next character of ones of the objects identified to yield a set of next characters, increasing a size of an area associated with each character of the set of next characters, and reducing the size of the area associated with each character of the set of next characters with time absent detection of a further touch.
