Abstract

A numeric keypad (100) for entering ideographic characters is provided. The numeric keypad (100) comprises a first set of input keys (102) corresponding to numerals 1, 2, 3, 4, and 5, and a second set of input keys (104) corresponding to numeral 6, 7, 8, 9, and 0. Each of the first set of input keys (102) has a predefined single character stroke, which complies with the GB18031 standard. The second set of input keys (104) is assigned a first particular sequence of the predefined single character strokes and a second particular sequence of the predefined single character strokes different from the first particular sequence of the predefined single character strokes.

Claims

1. A numeric keypad for entering ideographic characters, the numeric keypad comprising:

a first set of input keys corresponding to numerals 1, 2, 3, 4, and 5, each of the first set of input keys for entering a predefined single character stroke; and

a second set of input keys corresponding to numeral 6, 7, 8, 9, and 0, wherein at least one of the second set of input keys is assigned a first particular sequence of the predefined single character strokes and a second particular sequence of the predefined single character strokes different from the first particular sequence of the predefined single character strokes wherein the at least one second input key enters either the first or the second particular sequence.

2. The numeric keypad of claim 1, wherein each of the first particular sequence and the second particular sequence of the predefined single character strokes comprises two predefined single character strokes.

3. The numeric keypad of claim 1, wherein each of the second set of input keys is assigned a first particular sequence of the predefined single character strokes and a second particular sequence of the predefined single character strokes,

wherein each of the first particular sequences and the second particular sequences of the predefined single character strokes is unique.

4. The numeric keypad of claim 3, wherein each of the first particular sequences and the second particular sequences of the predefined single character strokes comprises two predefined single character strokes.

5. An electronic device capable of processing an ideographic character, the electronic device comprising:

a processor;

a numeric keypad for entering ideographic characters, the numeric keypad having a first set of input keys corresponding to numerals 1, 2, 3, 4, and 5, each of the first set of input keys entering a predefined single character stroke into the processor, and having a second set of input keys corresponding to numeral 6, 7, 8, 9, and 0,

wherein at least one of the second set of input keys is assigned a first particular sequence of the predefined single character strokes and a second particular sequence of the predefined single character strokes different from the first particular sequence of the predefined single character strokes and wherein the at least one of the second input keys enters either the first or the second particular sequence into the processor.

6. The electronic device of claim 5, wherein each of the first particular sequence and the second particular sequence of the predefined single character strokes comprises two predefined single character strokes.

7. The electronic device of claim 5, wherein each of the second set of input keys is assigned a first particular sequence of the predefined single character strokes and a second particular sequence of the predefined single character strokes,

wherein each of the first particular sequences and the second particular sequences of the predefined single character strokes is unique.

8. The electronic device of claim 7, wherein each of the first particular sequences and the second particular sequences of the predefined single character strokes comprises two predefined single character strokes.

9. A method for programming keys in an electronic device for entering an ideographic character using a numeric keypad, the numeric keypad having a first set of input keys corresponding to numerals 1, 2, 3, 4, and 5 and a second set of input keys corresponding to numerals 6, 7, 8, 9, and 0, the method comprising:

assigning each of the first set of input keys with a predefined single character stroke; and

assigning at least one of the second set of input keys with a first particular sequence of the predefined single character strokes and a second particular sequence of the predefined single character strokes different from the first particular sequence of the predefined single character strokes.

10. The method of claim 9, wherein each of the first particular sequence and the second particular sequence of the predefined single character strokes comprises two predefined single character strokes.

11. The method of claim 9, wherein each of the second set of input keys is assigned a first particular sequence of the predefined single character strokes and a second particular sequence of the predefined single character strokes,

wherein each of the first particular sequences and the second particular sequences of the predefined single character strokes is unique.

12. The method of claim 11, wherein each of the first particular sequences and the second particular sequences of the predefined single character strokes comprises two predefined single character strokes.
