Mobile electronic device and associated method enabling transliteration of a text input
View Patent ↗An improved mobile electronic device enables the inputting of text in one alphabet, Traditional Chinese in the present example, by transliteration of inputs in another alphabet, BoPoMoFo in the present example. Since some of the inputs can be ambiguous, transliteration of an ambiguous input is delayed until a detection of a finalization event, thus avoiding the outputting of unnecessary transliteration results, and thus advantageously avoiding a distraction to the user.
1. A method comprising:
detecting one or more character inputs in a first character alphabet as a preceding character string, the preceding character string corresponding to one or more valid characters in a second alphabet according to a transliteration operation;
detecting a current character input in the first character alphabet following input of the preceding character string;
determining, via a processor, whether the current character input is an ambiguous input; and
selectively suspending processing of the current character input by the transliteration operation.
2. The method of claim 1 , wherein the current character input is an ambiguous input when an input key used to input the current character input is associated with a plurality of characters in the first alphabet.
3. The method of claim 1 , further comprising:
continuing processing of the current character input upon occurrence of a finalization event, wherein the finalization event includes at least one of a detection of another input by a different input key within a predetermined period of time after the current input, and an expiration of the predetermined period of time after the current input without detecting another input.
4. The method of claim 1 , further comprising:
displaying the one or more valid characters as proposed transliterations in a lookup portion prior to detecting the current character input.
5. The method of claim 4 , wherein a proposed transliteration involving the current character input is not displayed in the lookup portion until a finalization event is received.
6. An electronic device comprising:
a memory storing instructions; and
a processor executing the instructions to:
detect one or more character inputs in a first character alphabet as a preceding character string, the preceding character string corresponding to one or more valid characters in a second alphabet according to a transliteration operation;
detect a current character input in the first character alphabet following input of the preceding character string;
determine whether the current character input is an ambiguous input; and
selectively suspend processing of the current character input by the transliteration operation.
7. The electronic device of claim 6 , wherein the current character input is an ambiguous input when an input key used to input the current character input is associated with a plurality of characters in the first alphabet.
8. The electronic device of claim 6 , the processor executing instructions to continue processing of the current character input upon occurrence of a finalization event, wherein the finalization event includes at least one of a detection of another input by a different input key within a predetermined period of time after the current input, and an expiration of the predetermined period of time after the current input without detecting another input.
9. The electronic device of claim 6 , the processor executing instructions to display the one or more valid characters as proposed transliterations in a lookup portion prior to detecting the current character input.
10. The electronic device of claim 9 , wherein a proposed transliteration involving the current character input is not displayed in the lookup portion until a finalization event is received.
11. A tangibly embodied non-transitory computer-readable storage medium storing instructions that, when executed by a processor of a device, cause the device to perform a method comprising:
detecting one or more character inputs in a first character alphabet as a preceding character string, the preceding character string corresponding to one or more valid characters in a second alphabet according to a transliteration operation;
detecting a current character input in the first character alphabet following input of the preceding character string;
determining whether the current character input is an ambiguous input; and
selectively suspending processing of the current character input by the transliteration operation.
12. The computer-readable storage medium of claim 11 , wherein the current character input is an ambiguous input when an input key used to input the current character input is associated with a plurality of characters in the first alphabet.
13. The computer-readable storage medium of claim 11 , further comprising:
continuing processing of the current character input upon occurrence of a finalization event, wherein the finalization event includes at least one of a detection of another input by a different input key within a predetermined period of time after the current input, and an expiration of the predetermined period of time after the current input without detecting another input.
14. The computer-readable storage medium of claim 11 , the method further comprising:
displaying the one or more valid characters as proposed transliterations in a lookup portion prior to detecting the current character input.
15. The computer-readable storage medium of claim 14 , wherein a proposed transliteration involving the current character input is not displayed in the lookup portion until a finalization event is received.
