Handheld electronic device and associated method providing disambiguation of an ambiguous input and selectively providing prediction of future characters
View Patent ↗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.
1. A method of enabling input on a handheld electronic device that comprises an output apparatus, an input apparatus comprising a plurality of input members, and a processor apparatus comprising a memory having stored therein a number of routines, one of the routines being a prediction routine that is executable on the processor apparatus and is structured, responsive to an input, to output a number of proposed completions of the input, each proposed completion comprising a number of data elements additional to the input, the method comprising:
responsive to an ambiguous text input comprising a plurality of input member actuations, outputting a list comprising a number of disambiguated interpretations and a number of proposed completions of the ambiguous text input; and
directly responsive to a deletion input, outputting another list comprising a number of disambiguated interpretations of the ambiguous text input as modified by the deletion input, the another list being free of proposed completions.
2. The method of claim 1 , further comprising detecting another input member actuation, and outputting a number of disambiguated interpretations and a number of proposed completions of the ambiguous text input as modified by the deletion input plus the another input member actuation.
3. The method of claim 2 , further comprising detecting as the another input member actuation an input appended to the end of the ambiguous text input as modified by the deletion input.
4. A handheld electronic device comprising:
a processor apparatus comprising a processor and a memory having stored therein a number of routines, one of the routines being a prediction routine that is executable on the processor and is structured, responsive to an input, to output a number of proposed completions of the input, each proposed completion comprising a number of data elements additional to the input;
an input apparatus comprising a plurality of input members and being structured to provide input to the processor apparatus;
an output apparatus structured to receive output signals from the processor apparatus;
the memory further having stored therein a number of routines which, when executed on the processor, cause the handheld electronic device to perform operations comprising:
responsive to an ambiguous text input comprising a plurality of input member actuations, outputting a list comprising a number of disambiguated interpretations and a number of proposed completions of the ambiguous text input; and
directly responsive to a deletion input, outputting another list comprising a number of disambiguated interpretations of the ambiguous text input as modified by the deletion input, the another list being free of proposed completions.
5. The handheld electronic device of claim 4 wherein the operations further comprise detecting another input member actuation, and outputting a number of disambiguated interpretations and a number of proposed completions of the ambiguous text input as modified by the deletion input plus the another input member actuation.
6. The handheld electronic device of claim 5 wherein the operations further comprise detecting as the another input member actuation an input appended to the end of the ambiguous text input as modified by the deletion input.
