Abstract
Abstract An apparatus (100) and method for inputting ideographic characters. The apparatus (100) has an input pad with a predetermined number of input keys (102, . . . 111). Theoretically, at least a stroke and a radical are mapped to each input key (102, . . . 111). After the apparatus (100) receives at least a first and a second input key entry, based on a number of input key entries received, the apparatus (100) determines whether the first input key entry is one of the following: a stroke and a radical. Thus, the method solves the ambiguity problems caused by such a mapping of the apparatus.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
100 words
A method for inputting ideographic characters comprising the steps of: receiving a first input key entry, a second input key entry and a third input key entry in chronological order; interpreting that the first input key entry represents a radical when a fourth input key entry is received; interpreting that the first input key entry represents a first stroke when a function key entry is received; and displaying, responsive to the steps of receiving and interpreting, a set of ideographic characters in descending order of probability of being a desired character, wherein probability is indicative of a frequency of use.
Claim 2
Independent Claim
100 words
A method for inputting ideographic characters comprising the steps of: receiving a first input key entry, a second input key entry and a third input key entry in chronological order; interpreting that the first input key entry represents a radical when a fourth input key entry is received; interpreting that the first input key entry represents a first stroke when a function key entry is received; and displaying, responsive to the steps of receiving and interpreting, a set of ideographic characters in descending order of probability of being a desired character, wherein probability is indicative of a frequency of use.
Claim 3
Dependent Claim
79 words
The method of claim 1 further comprising the steps of, when the first input key entry represents a radical: interpreting that the second input key entry represents a first stroke; interpreting that the third input key entry represents a second stroke; interpreting that the fourth input key entry represents a third stroke; and wherein the step of displaying comprises displaying a set of possible ideographic characters having the radical followed by at least the first, second and third strokes.
Claim 4
Dependent Claim
80 words
The method of claim 1 further comprising the steps of, when the first input key entry represents a first stroke: interpreting that the second input key entry represents a second stroke; interpreting that the third input key entry represents a third stroke; and excluding radicals represented by the input keys from a set of possible ideographic characters; and wherein the step of displaying comprises displaying the set of possible ideographic characters having at least the first, second and third strokes.
Claim 5
Dependent Claim
53 words
The method of claim 3, further comprising the step of ranking, prior to the step of displaying, the set of possible ideographic characters in descending order of probability of containing a desired ideographic characters based on the order in which the input keys are received, wherein probability is indicative of frequency of use.
