Abstract: A handheld electronic device includes a keypad having a plurality of keys and a selection member; a display component; and a processor cooperating with the keypad and the display component to provide a display at the display component. The display includes a first representation of a plurality of the keys, and at least one of: (a) a second representation of an activated one of the input members, (b) a third representation including a plurality of diacritics disposed about an activated one of the input members, and (c) a fourth representation including a plurality of diacritics disposed about an activated one of the input members, and a direction of selection between the activated one of the input members and one of the diacritics. The processor cooperates with the selection member to adjust the direction of selection, and select one of the diacritics for display by the display component.

Abstract: A handheld device includes a plurality of input members, a first set of which each have a Roman character assigned thereto, a least some of which have a first non-Roman and a second non-Roman character assigned thereto. In response to an actuation of a first one of the input members, a first one of the non-Roman characters that is assigned to the first one of the input members is displayed. Based on one or more rules which govern permissible character sequences in the subject language, the display of a second one of the non-Roman characters in response to an actuation of a second one of the input members having the second one of the non-Roman characters assigned thereto immediately following the actuation of said first one of the input members is prevented.

Abstract: A mobile computing device that operates a method that processes handwritten user input for character matching and predictive word matching. A user inputs handwritten input on a touch-sensitive display using, for example, a stylus. The method determines and displays a set of candidate character matches for the handwritten input. The user then selects a character from the candidate character matches. The method determines and displays a set of candidate predicted word matches based on the user selected character match. The user can then select to input a desired candidate predicted word match.

Abstract: An electronic device for non-Roman text input, the device comprising: a non-Roman text input module resident in the memory for execution by the microprocessor, the non-Roman text input module being configured to: provide a non-Roman text input interface for display on the output device, the interface being adapted for non-Roman text input in a first language; receive a signal representing a non-Roman text input in response to an input using the interface; determine a non-Roman character corresponding to the non-Roman text input, the non-Roman character being determined according to one or more rules for determining a compound non-Roman character based on the non-Roman text input in combination with a preceding input; and transmit a signal representing the determined non-Roman character for display on the output device.

Abstract: A method of determining character value arrangement on a handheld keypad includes: specifying one or more parameters for evaluating keypad solutions for the handheld keypad by characterizing a user's physical operations on the handheld keypad; generating an initial set of keypad solutions for the handheld keypad; evaluating a fitness of the keypad solutions in the initial set based on the one or more parameters; selecting a first set of keypad solutions from the initial set based on the fitness of the keypad solutions in the initial set; generating additional solutions for the first set of keypad solutions from the keypad solutions in the first set; evaluating the fitness of the additional keypad solutions in the first set; and saving at least some key-associated character values based on the keypad solutions. The keypad includes input keys with which character values are associated, each having at least one alphanumeric indicia associated therewith.
