Abstract

An improved mobile electronic device and associated method enable the identification of previously-entered textual objects in one or more custom wordlists to identify possible transliterations of textual inputs. Such textual objects can be stored as data in a Pinyin custom wordlist if it is in the nature of Standard Mandarin characters or it can be stored in a BoPoMoFo custom wordlist if it is in the nature of Traditional Chinese characters, or it can be stored in both if it is in the nature of both Standard Mandarin characters and Traditional Chinese characters.

Claims

1. A method of enabling text input on a mobile electronic device, the method comprising:

detecting on the mobile electronic device an initial input of a textual object comprising a number of characters, each character being of a first type, of a second type, or of both;

performing a storage operation comprising at least one of;

responsive to a determination that all of the characters are of at least the first type, storing a first representation of the textual object in a first data source, and

responsive to a determination that all of the characters are of at least the second type, storing a second representation of the textual object in a second data source;

detecting a textual input in one of a first alphabet that can be transliterated into characters of at least the first type and a second alphabet that can be transliterated into characters of at least the second type;

when the textual input is in the first alphabet, comparing the textual input with the first data source to identify the first representation of the textual object;

when the textual input is in the second alphabet, comparing the textual input with the second data source to identify the second representation of the textual object; and

outputting the textual object as a proposed transliteration of the textual input.

2. The method of claim 1, further comprising storing with at least one of the first representation of the textual object and the second representation of the textual object a representation of a string of characters which can be transliterated into the textual object.

3. The method of claim 1, further comprising:

performing as at least a portion of the storage operation a making of a determination that all of the characters of the textual object are of both the first type and the second type and, responsive thereto, storing a first representation of the textual object in the first data source a second representation of the textual object in the second data source; and

outputting the textual object as a proposed transliteration of the textual input regardless or whether the textual input is in the first alphabet or the second alphabet.

4. The method of claim 1, further comprising:

detecting as the textual input an incomplete input; and

outputting the textual object as both a proposed transliteration of the textual input and a proposed completion of the textual input.

5. A mobile electronic device comprising:

a processor apparatus comprising a processor and a memory;

an input apparatus structured to provide input to the processor apparatus;

an output apparatus structured to receive output signals from the processor apparatus; and

the memory having stored therein a number of routines which, when executed on the processor, cause the mobile electronic device to perform operations comprising;

detecting on the mobile electronic device an initial input of a textual object comprising a number of characters, each character being of a first type, of a second type, or of both;

performing a storage operation comprising at least one of;

responsive to a determination that all of the characters are of at least the first type, storing a first representation of the textual object in a first data source, and

responsive to a determination that all of the characters are of at least the second type, storing a second representation of the textual object in a second data source;

detecting a textual input in one of a first alphabet that can be transliterated into characters of at least the first type and a second alphabet that can be transliterated into characters of at least the second type;

when the textual input is in the first alphabet, comparing the textual input with the first data source to identify the first representation of the textual object;

when the textual input is in the second alphabet, comparing the textual input with the second data source to identify the second representation of the textual object; and

outputting the textual object as a proposed transliteration of the textual input.

6. The mobile electronic device of claim 5 wherein the operations further comprise storing with at least one of the first representation of the textual object and the second representation of the textual object a representation of a string of characters which can be transliterated into the textual object.

7. The mobile electronic device of claim 5 wherein the operations further comprise:

performing as at least a portion of the storage operation a making of a determination that all of the characters of the textual object are of both the first type and the second type and, responsive thereto, storing a first representation of the textual object in the first data source a second representation of the textual object in the second data source; and

outputting the textual object as a proposed transliteration of the textual input regardless or whether the textual input is in the first alphabet or the second alphabet.

8. The mobile electronic device of claim 5 wherein the operations further comprising:

detecting as the textual input an incomplete input; and

outputting the textual object as both a proposed transliteration of the textual input and a proposed completion of the textual input.

9. A machine-readable storage medium comprising instructions which, when executed on a mobile electronic device, cause the mobile electronic device to perform operations comprising:

detecting on the mobile electronic device an initial input of a textual object comprising a number of characters, each character being of a first type, of a second type, or of both;

performing a storage operation comprising at least one of;

responsive to a determination that all of the characters are of at least the first type, storing a first representation of the textual object in a first data source, and

responsive to a determination that all of the characters are of at least the second type, storing a second representation of the textual object in a second data source;

detecting a textual input in one of a first alphabet that can be transliterated into characters of at least the first type and a second alphabet that can be transliterated into characters of at least the second type;

when the textual input is in the first alphabet, comparing the textual input with the first data source to identify the first representation of the textual object;

when the textual input is in the second alphabet, comparing the textual input with the second data source to identify the second representation of the textual object; and

outputting the textual object as a proposed transliteration of the textual input.

10. The machine-readable storage medium of claim 9 wherein the operations further comprise storing with at least one of the first representation of the textual object and the second representation of the textual object a representation of a string of characters which can be transliterated into the textual object.

11. The machine-readable storage medium of claim 9 wherein the operations further comprise:

performing as at least a portion of the storage operation a making of a determination that all of the characters of the textual object are of both the first type and the second type and, responsive thereto, storing a first representation of the textual object in the first data source a second representation of the textual object in the second data source; and

outputting the textual object as a proposed transliteration of the textual input regardless or whether the textual input is in the first alphabet or the second alphabet.

12. The machine-readable storage medium of claim 9 wherein the operations further comprising:

detecting as the textual input an incomplete input; and

outputting the textual object as both a proposed transliteration of the textual input and a proposed completion of the textual input.
