Abstract: A system and method is disclosed that provides for character or text selection and editing. The text and character selection is made by user contact with a touch sensitive screen. In order to allow for refinement of the selection, a second expanded view is implemented as compared to the original display configuration of the screen. Furthermore, the selection is described in relation to two endpoints of the block of text. Additionally, a point is specified as the point desired for insertion of the selected text. The expanded view is implemented along with the original view as required when making character selection.

Abstract: A manual input navigation device and a sensor are utilized to manipulate graphical elements in a mobile device graphical user interface. The manual input navigation device generates an input navigation signal for altering a relative position of the graphical element in the graphical user interface, and the sensor measures a current tilt angle of the mobile device. Upon the generation of the input navigation signal, the current tilt angle is stored as a reference tilt angle. The relative position of the graphical element is altered based on the difference between the current tilt angle and the reference tilt angle.

Abstract: An improved handheld electronic device and associated method enable the phonetic inputting of text using a reduced keyboard and transformation algorithm. The handheld electronic device and method advantageously enable the inputting of languages such as Chinese, Japanese, Korean, and the like without limitation. The transformation algorithm subjects each of a number of linguistic element permutations to an algorithm such as the Maximum Matching Algorithm or other algorithm to generate a string of words. The transformation algorithm then selects one string of words as a default textual output based on at least one of its minimal number of words and its relatively high attributed frequency value.

Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software and prediction software. In response to an ambiguous input, the system provides one or more disambiguated interpretations of the ambiguous input. In some circumstances, the system can additionally provide one or more completions, i.e., predictions of future characters. However, in other circumstances the outputting of completions of an ambiguous input can be suppressed in order to avoid distracting the user and to provide more meaningful results to the user.

Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software and prediction software. During editing of an object, the object can be ambiguous, and the system provides one or more disambiguated interpretations of the ambiguous object. In some circumstances, the system can additionally provide one or more completions, i.e., predictions of future characters. However, in other circumstances the outputting of completions of an ambiguous object can be suppressed in order to avoid distracting the user and to provide more meaningful results to the user.

Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with text 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 includes a number of non-alphabetic characters that are assigned to keys and that can be accessed directly by the text disambiguation software without the need to active a non-alphabetic input routine or to additionally actuate and <SHIFT> key or an <ALT> key, for instance.

Abstract: An electronic mobile device that includes a controller including at least one processor, for controlling operation of the mobile device, a display coupled to the controller, and a navigational input mechanism coupled to the controller and responsive to user manipulation thereof. The controller, in one input mode, moves a selection marker on a user interface screen on the display in response to user manipulation of the navigational input mechanism, and in a second input mode, authenticates a user of the device in dependence on a sequence of input events resulting from user manipulation of the navigational input mechanism matching a predetermined passcode sequence.
