Abstract

A Chinese character input device and method thereof are described. The Chinese character input device includes a database, a touch panel and a processing module. The database stores multiple candidate characters, multiple initial consonants and multiple rhymes. Each candidate character is composed of at least one initial consonant and at least one rhyme. The touch panel displays a virtual keyboard including initial consonant virtual keys and rhyme virtual keys and receives a command. The command includes a touch on an initial consonant virtual key to determine an input initial consonant and a release at a rhyme virtual key to determine an input rhyme. The processing module is connected to the database and compares the input initial consonant and input rhyme with the initial consonants and rhymes in the database to generate at least one corresponding candidate character and displays the candidate character on the touch panel for selecting.

Claims

1. A Chinese character input device comprising:

a database storing multiple candidate characters, multiple initial consonants and multiple rhymes, wherein the candidate character is composed of at least one initial consonant and at least one rhyme;

a touch panel displaying a virtual keyboard and determining an input rhyme and an input initial consonant when receiving a command that comprise a touch and a release of the virtual keyboard; and

a processing module connected to the database and comparing the input rhyme, the input initial consonant with the initial consonants and the rhymes stored in the database, thereby generating at least one corresponding candidate character and displaying the candidate characters on the touch panel for selecting.

2. The Chinese character input device according to claim 1, wherein the virtual keyboard at least comprises multiple initial consonant virtual keys and multiple rhyme virtual keys, and the command comprises a touch on one of the initial consonant virtual keys of the virtual keyboard to determine the input initial consonant, and a release at one of the rhyme virtual keys to determine the input rhyme.

3. The Chinese character input device according to claim 1, wherein the database further stores multiple candidate words, and each of the candidate words is composed of at least two candidate characters.

4. The Chinese character input device according to claim 3, wherein when the processing module receives multiple commands continuously, the database retrieves at least one candidate word composed of candidate characters corresponding to the commands, and the touch panel displays the at least one candidate word for selecting.

5. The Chinese character input device according to claim 1, wherein the database further stores multiple head vowels, and the touch panel further determines an input head vowel when the command is received, and the processing module further compares the input head vowel with the head vowels stored in the database to generate the at least one corresponding candidate character.

6. The Chinese character input device according to claim 5, wherein the virtual keyboard at least comprises multiple initial consonant virtual keys, multiple rhyme virtual keys and multiple head vowel virtual keys.

7. The Chinese character input device according to claim 6, wherein the command comprises a touch on one of the initial consonant virtual keys to determine the input initial consonant, a drag and a stay over one of the head vowel virtual keys to determine the input head vowel, and a release at one of the rhyme virtual keys to determine the input rhyme.

8. A Chinese character input method cooperating with an electronic device with a touch panel, wherein the electronic device stores multiple initial consonants, multiple rhymes and multiple candidate characters being composed of at least one initial consonant and at least one rhyme, and the touch panel displays a virtual keyboard with initial consonant virtual keys and rhyme virtual keys, the Chinese character input method comprising the steps of:

receiving a command that comprise a touch and a release of the virtual keyboard and determining an input initial consonant and an input rhyme; and

comparing the input initial consonant and the input rhyme with the initial consonants and the rhymes stored in the electronic device to generate at least one corresponding candidate character, and

displaying the corresponding candidate character on the touch panel for selecting.

9. The Chinese character input method according to claim 8, wherein the command comprises a touch on one of the initial consonant virtual keys of the virtual keyboard to determine the input initial consonant, and a release at one of the rhyme virtual keys of the virtual keyboard to determine the input rhyme.

10. The Chinese character input method according to claim 8, further comprising:

storing multiple candidate words in the electronic device, wherein each of the candidate words is composed of at least two candidate characters.

11. The Chinese character input method according to claim 10, wherein when multiple commands are received continuously, the Chinese character input method further comprises the step of:

retrieving at least one candidate word composed of candidate characters corresponding to the commands; and

displaying the candidate words on the touch panel for selecting.

12. A Chinese character input method cooperating with an electronic device having a touch panel, wherein the electronic device stores multiple initial consonants, multiple head vowels, multiple rhymes and multiple candidate characters being composed of at least one initial consonant, head vowel and rhyme, the touch panel displays a virtual keyboard with multiple initial consonant virtual keys, multiple head vowel virtual keys and multiple rhyme virtual keys, the Chinese character input method comprising steps of:

receiving a command that comprise a touch, a stay and a release of the virtual keyboard and determining an input initial consonant, an input head vowel and an input rhyme; and

comparing the input initial consonant, the input head vowel and the input rhyme with the initial consonants, the head vowels and the rhymes stored in the electronic device; and

displaying the candidate character composed of the initial consonant, head vowel and rhyme that corresponding to the input initial consonant, the input head vowel and the input rhyme on the touch panel for selecting.

13. The Chinese character input method according to claim 12, wherein the command comprises a touch on one of the initial consonant virtual keys of the virtual keyboard to determine the input initial consonant, a drag and stay over one of the head vowel virtual keys of the virtual keyboard to determine the input head vowel, and a release at one of the rhyme virtual keys of the virtual keyboard to determine the input rhyme.

14. The Chinese character input method according to claim 12, further comprising:

storing multiple candidate words in the electronic device, wherein each of the candidate words is composed of at least two candidate characters.

15. The Chinese character input method according to claim 12, wherein when multiple commands are received continuously, the Chinese character input method further comprises the step of:

retrieving the candidate words composed of candidate characters corresponding to the commands; and

displaying the candidate words on the touch panel for selecting.
