Apparatus and method for input of ideographic Korean syllables from reduced keyboard
First Claim
1. A method for input of text symbols into an electronic device comprising a reduced keyboard, the reduced keyboard having keys representing a plurality of characters, the method comprising the steps of:
- receiving character inputs from the reduced keyboard;
identifying symbol variants based on the received character inputs;
grouping each symbol variant in one of a plurality of groups of symbol variants according to a type of the symbol variant, each of the plurality of groups having an associated priority;
ranking the symbol variants within at least one of the groups of symbol variants in decreasing order of frequencies of use of the symbol variants;
displaying a list of symbol variants comprising the plurality of groups of symbol variants in order of decreasing priority; and
selecting an input symbol from the list of symbol variants,wherein the symbol variants of the at least one of the groups of symbol variants are sorted by both priority and frequency of use;
wherein the text symbols comprise Korean text symbols, and wherein the plurality of groups of symbol variants comprise a Hangul syllables group, a compound Jamo characters group, a basic Jamo characters group, and a group of sequences of characters that violate Korean grammar rules.

Abstract
Systems and methods for input of text symbols into an electronic device comprising a reduced keyboard having keys representing a plurality of characters are disclosed. Possible symbol variants are identified based on character inputs received from the reduced keyboard. Each identified symbol variant is grouped into one of a plurality of groups of symbol variants, each group having an associated priority, according to a type of the symbol variant. Within at least one of the groups, the symbol variants are ranked in decreasing order of frequencies of use of the symbol variants. A list of symbol variants comprising the plurality of groups of symbol variants in order of decreasing priority is then displayed, and an input symbol is selected from the list of symbol variants. The symbol variants of the at least one of the groups of symbol variants are thereby sorted by both priority and frequency of use.

14. A system of inputting text symbols into an electronic device, comprising:
-
a reduced keyboard having keys representing a plurality of characters for composing text symbols; an input queue configured to receive character inputs from the reduced keyboard; a memory configured to store frequency of use information for a plurality of symbols; an input processor operatively coupled to the memory and the input queue and configured to identify possible symbol variants comprising text symbols at least partially composed of the received character inputs, to assign each of the symbol variants to one of a plurality of groups of symbol variants having associated priorities according to a type of the symbol variant, to sort the symbol variants within at least one of the groups based on the frequency of use information stored in the memory, and to select an input symbol from the list of symbol variants; a display; and a user interface coupled between the display and the input processor to display a list of symbol variants comprising the groups of symbol variants in order of decreasing priority on the display; wherein the plurality of characters include Korean Jamo characters, and wherein the plurality of groups comprise a Korean Hangul syllable group, a compound Jamo character group, and a basic Jamo character group. - View Dependent Claims (15, 16, 17)

18. A computer-readable medium storing software code instructions for inputting text symbols into an electronic device comprising a reduced keyboard representing a plurality of characters, the software code instructions comprising instructions for performing the functions of:
-
receiving character inputs from the reduced keyboard; identifying symbol variants based on the received character inputs; grouping each symbol variant in one of a plurality of groups of symbol variants according to a type of the symbol variant, each of the plurality of groups having an associated priority; ranking the symbol variants within at least one of the groups of symbol variants in decreasing order of frequencies of use of the symbol variants; displaying a list of symbol variants comprising the plurality of groups of symbol variants in order of decreasing priority; and selecting an input symbol from the list of symbol variants, wherein the symbol variants of the at least one of the groups of symbol variants are sorted by both priority and frequency of use; wherein the text symbols comprise Korean text symbols, and wherein the plurality of groups of symbol variants comprise a Hangul syllables group, a compound Jamo characters group, a basic Jamo characters group, and a group of sequences of characters that violate Korean grammar rules.
