An electronic device for disambiguation of stroke input, the device comprising: an input device coupled to the microprocessor for accepting a stroke input; and a stroke disambiguation module resident in the memory for execution by the microprocessor. The device is configured to: receive a signal representing a stroke input sequence at the stroke disambiguation module; apply one or more stroke disambiguation rules to the stroke input sequence to generate an updated input sequence; and transmit a signal representing the updated input sequence.

System and method for disambiguation of stroke input

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.

Handheld electronic device and associated method enabling text input in a language employing non-roman characters

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, second non-Roman character, and third non-Roman characters assigned thereto. The device is switchable between first and second modes. In the first mode, each Roman character may be input in response to actuation of the input member to which it is assigned, and in the second mode, each first non-Roman character may be input in response to a first type of actuation of the input member to which it is assigned, each second non-Roman character may input in response to a second type of actuation of the input member to which it is assigned, and each third non-Roman character may be input in response to a third type of actuation of the input member to which it is assigned.
