Patent ID: 8898584

Claim:
A method of enabling input on a mobile electronic device of a type comprising an input/output apparatus that comprises a touch sensitive display, and a processor apparatus that comprises a memory having stored therein a plurality of objects including a number of routines and a number of language objects, the mobile electronic device being switchable between an ambiguous text input mode and an unambiguous text input mode, the method comprising: operating the mobile electronic device in the ambiguous text input mode; displaying, while in the ambiguous text input mode, a reduced keyboard on the touch sensitive display, the reduced keyboard including a plurality of virtual keys, wherein at least some of the virtual keys each has a plurality of linguistic characters assigned thereto; detecting an ambiguous text input reflecting one or more selections of the virtual keys, wherein at least one selection corresponds to a plurality of potential linguistic characters; outputting as uncommitted alternative character strings a plurality of proposed text disambiguations of the ambiguous text input, the plurality of proposed text disambiguations based in part on the plurality of potential linguistic characters corresponding to the at least one selection, the plurality of proposed text disambiguations comprising a default disambiguation and a number of variant disambiguations, at least some of the text disambiguations each comprising at least some of the initial characters of a language object in the memory; switching the mobile electronic device to operate in the unambiguous text input mode in response to a predetermined event; displaying, when switching to the unambiguous text input mode, a full keyboard on the touch sensitive display, wherein each key of the full keyboard has at most a single linguistic character; and automatically converting the default disambiguation into a committed unambiguous character string when switching from the ambiguous text input mode to the unambiguous text input mode.
