Method and system for rendering diacritic characters
A method and system for enabling input of diacritic characters on a handheld electronic device. The method includes detecting an input associated with a selected key and determining a likelihood that the input reflects selection of a diacritic character. The time after which the set of possible diacritic characters that are utilized is rendered in response to a selected key being engaged in a press-and-hold operation is based on the determined likelihood.
1. A method of enabling input on a handheld electronic device comprising:
detecting an input associated with a selected key;
determining a likelihood that the input reflects selection of a diacritic character from a set of one or more diacritic characters associated with the selected key;
rendering the set of the one or more diacritic characters when the likelihood meets or exceeds a threshold value following expiration of a first period of time that the selected key is engaged in a press-and-hold operation; and
rendering the set of the one or more diacritic characters when the likelihood is below the threshold value following expiration of a second period of time longer than the first period of time, that the selected key is engaged in a press-and-hold operation.
2. The method of claim 1 , wherein the second period of time is a function of the determined likelihood.
3. The method of claim 1 , wherein the likelihood is determined based on a probability calculation utilizing all of possible diacritic characters that are associated with the selected key.
4. The method of claim 1 , wherein the first period of time is less than half the second period of time.
5. The method of claim 1 , further comprising detecting a language for the input prior to the step of determining the likelihood whether the input reflects selection of the diacritic character.
6. The method of claim 5 , wherein the step of determining the likelihood that the input reflects selection of the diacritic character is one of; based on the language, includes utilizing a dictionary stored by the handheld electronic device that corresponds to the language, or includes utilizing a language rule set handheld electronic device that corresponds to the language.
7. The method of claim 5 , wherein the step of detecting the language comprises one of; detecting a selection of a predetermined language by a user of the handheld electronic device, analyzing a metadata of a message previously received by the handheld electronic device, or analyzing heuristically a message previously received by the handheld electronic device.
8. A handheld electronic device comprising:
one or more input members that are capable of being actuated;
a processor;
a memory in electronic communication with the processor, the memory storing one or more routines executable by the processor, the one or more routines being adapted to:
detect an input associated with a selected key;
determine a likelihood that the input reflects selection of a diacritic character from a set of one or more diacritic characters associated with the selected key;
render a set of the one or more diacritic characters when the likelihood meets or exceeds a threshold value following expiration of a first period of time that the selected key is engaged in a press-and-hold operation; and
render the set of the one or more diacritic characters when the likelihood is below the threshold value following expiration of a second period of time longer than the first period of time, that the selected key is engaged in a press-and-hold operation.
9. The handheld device of claim 8 , wherein the second period of time is a function of the determined likelihood.
10. The handheld device of claim 8 , wherein the likelihood is determined based on a probability calculation that utilizes all of possible diacritic characters that are associated with the selected key.
11. The handheld device of claim 8 , wherein the first period of time is less than half the second period of time.
12. The handheld device of claim 8 , wherein the one or more routines are further adapted to detect a language for the input prior to the step of determining the likelihood whether the input reflects selection of a diacritic character.
13. The handheld device of claim 12 , wherein the determination of the likelihood that the inputs reflects selection of a diacritic character is on one of; based on the language, utilizes a dictionary stored by said handheld electronic device that corresponds to the language, or utilizes a language rule set handheld electronic device that corresponds to the language.
14. The handheld device of claim 12 , wherein the language detection comprises one of; detect a selection of a predetermined language by a user of the handheld electronic device, analyze a metadata of a message previously received by the handheld electronic device, or analyze heuristically a message previously received by the handheld electronic device.
15. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, when executed by a computing device, cause the device to:
detect an input associated with a selected key;
determine a likelihood that the input reflects selection of a diacritic character from a set of one or more diacritic characters associated with the selected key;
render a set of the one or more diacritic characters when the likelihood meets or exceeds a threshold value following expiration of a first period of time that the selected key is engaged in a press-and-hold operation; and
render the set of the one or more diacritic characters when the likelihood is below the threshold value following expiration of a second period of time longer than the first period of time, that the selected key is engaged in a press-and-hold operation.
16. The non-transitory computer readable storage medium of claim 15 , wherein the second period of time is a function of the determined likelihood.
17. The non-transitory computer readable storage medium of claim 15 , wherein the likelihood is determined based on a probability calculation that utilizes all of possible diacritic characters that are associated with the selected key.
18. The non-transitory computer readable storage medium of claim 15 , wherein the first period of time is less than half the second period of time.
19. The non-transitory computer readable storage medium of claim 15 , wherein the one or more routines are further adapted to detect a language for the input prior to the step of determining the likelihood whether the input reflects selection of a diacritic character.
20. The non-transitory computer readable storage medium of claim 19 , wherein the determination of the likelihood that the input reflects selection of the diacritic character is one of; based on the language, utilizes a dictionary stored by said handheld electronic device that corresponds to the language, or utilizes a language rule set handheld electronic device that corresponds to the language.
21. The non-transitory computer readable storage medium of claim 19 , wherein the language detection comprises one of; detect a selection of a predetermined language by a user of the handheld electronic device, analyze a metadata of a message previously received by the handheld electronic device, or analyze heuristically a message previously received by the handheld electronic device.
