Abstract

An information processing method including memorizing pattern information, memorizing use information of said pattern information memorized, and displaying said pattern information memorized and said use information of said pattern information.

Claims

1. An information processing method using a recognition dictionary for recognizing a predetermined stroke pattern designated by a user as a specific character, said method comprising the steps of:

memorizing a usage frequency of recognition for each specific character; and

displaying a list of the specific characters, wherein the specific characters are displayed with different density in accordance with the usage frequency of recognition.

2. An information processing method according to claim 1, wherein the usage frequency of recognition is the number of times the specific character is selected as a recognition candidate.

5. A method according to claim 1, wherein the usage frequency is a relative actual usage frequency.

6. A method according to claim 1, wherein the recognition dictionary stores stroke patterns.

7. A method according to claim 1, wherein said stroke pattern is used for recognition of handwritten characters.

8. A method according to claim 7, wherein said usage frequency is updated whenever the recognition of handwritten characters is executed.

9. A method according to claim 1, wherein the usage frequency is displayed upon the list in said displaying step.

15. An information processing method according to claim 1, wherein said list is displayed on a display screen of a liquid crystal display or a cathode ray tube in said displaying step.

19. An information processing method according to claim 1, further comprising a step of deleting information from the recognition dictionary.

3. An information processing apparatus comprising:

a recognition dictionary which is used for recognizing a predetermined stroke pattern designated by a user as a specific character;

means for memorizing a usage frequency of recognition for each specific character; and

means for displaying a list of the specific characters, wherein the specific characters are displayed with different density in accordance with the usage frequency of recognition.

4. An information processing apparatus according to claim 3, wherein the usage frequency of recognition is the number of times the specific character is selected as a recognition candidate.

10. An apparatus according to claim 3, wherein the usage frequency is a relative actual usage frequency.

11. An apparatus according to claim 3, wherein the recognition dictionary stores stroke patterns.

12. An apparatus according to claim 3, wherein said stroke pattern is used for recognition of handwritten characters.

13. An apparatus according to claim 12, wherein said usage frequency is updated whenever the recognition of handwritten characters is executed.

14. An apparatus according to claim 3, wherein said display means displays the usage frequency upon displaying the list of specific characters.

16. An information processing apparatus according to claim 3, wherein said means for displaying comprises a display screen of a liquid crystal display or a cathode ray tube.

20. An information processing apparatus according to claim 3, further comprising means for deleting information from the recognition dictionary.

17. A computer-readable medium encoded with a program using a recognition dictionary for recognizing a predetermined stroke pattern designated by a user as a specific character, the program performing the steps of:

memorizing a usage frequency of recognition for each specific character; and

displaying a list of the specific characters, wherein the specific characters are displayed with different density in accordance with the usage frequency of recognition.

18. A computer-readable medium according to claim 17, wherein the usage frequency of recognition is the number of times the specific character is selected as a recognition candidate.

21. A computer-readable medium according to claim 17, wherein the program further performs a step of deleting information from the recognition dictionary.
