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

摘要

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.

主权项

1. A handheld electronic device comprising:
a processor apparatus comprising a processor and a memory; an input apparatus comprising a plurality of input keys and being structured to provide input to the processor apparatus, a first set of the input keys each having one or more non-Roman characters assigned thereto, said non-Roman characters being employed in a first language, said first language having one or more rules that govern use of characters in the first language; and an output apparatus structured to receive output signals from the processor apparatus, wherein the memory has stored therein a number of routines that, when executed on the processor, cause the processor to:
receive an input requesting entry of a first one of the non-Roman characters on a first one of the first set of input keys;determine that said input is for beginning a new word; andbased on said one or more rules, determine that said first one of the non-Roman characters is not permissible for beginning said new word and prevent display on said output apparatus of said first one of the non-Roman characters.
