Abstract

An information processing apparatus with a hand-writing character recognition function includes an input device having a pen and tablet for inputting a user'"'"'s hand-writing character information, and a selecting device for selecting a desired block type character on the basis of the hand-writing character information, selection of the block type character (corresponding to the hand-writing character information) being effected by the hand-writing character recognition function. A detecting device detects a similarity condition between first and second hand-written characters initially input by the user on the input device, and hand-writing character information for the user based on the first and second hand-written character is registered if the similarity condition was detected. Subsequently, if the user inputs a hand-written character similar to the user'"'"'s registered hand-writing character information, the input hand-written character is translated into the desired block type character.

Claims

1. An information processing apparatus with a hand-writing character recognition function, said apparatus comprising:

input arbitrary means comprising pen means and a tablet for inputting hand-writing character information of a user;

selecting means for selecting an arbitrary desired block type character on the basis of said hand-writing character information, selection of said block type character corresponding to said hand-writing character information being effected by said hand-writing character recognition function;

detecting means for detecting a similarity condition between first and second hand-written characters input by the user on said input means, said first and second hand-written characters relating to a particular block type character; and

registering means for registering the user'"'"'s hand-writing character information based on said first and second hand-written characters only in response to detection of said similarity condition by said detecting means, wherein after input by the user of a hand-written character similar to said user'"'"'s registered hand-writing character information, the input hand-written character is translated into said desired block type character.

2. An information processing apparatus according to claim 1, further comprising a display means beneath said tablet, wherein an image displayed on said display means is visible through said tablet.

3. An information processing apparatus according to claim 2, wherein each of said hand-written characters is displayed on said display means in a real time manner when the user inputs each said hand-written character.

4. An information processing apparatus according to claim 1, wherein a mode for registering said user'"'"'s hand-writing character information is selected by opening a registering window.

5. An information processing apparatus according to claim 4, wherein said registering window has a first area for displaying said desired block type character and a second area for inputting each said hand-written character by using said pen means.

6. An information processing apparatus according to claim 5, wherein said first area is used to display a word formed of Roman letters, and said second area is used to input a hand-written representation of the word.

7. An information processing apparatus according to claim 1, wherein said apparatus is a portable computer.

8. An information processing method using a hand-writing character recognition function, said method comprising the steps of:

selecting a desired block type character on the basis of input hand-writing character information, selection of said block type character corresponding to said hand-writing character information being effected by said hand-writing character recognition function;

inputting a first hand-written character by a user on input means;

inputting a second hand-written character by the user on said input means;

detecting a similarity condition between said first and second hand-written characters; and

registering the user'"'"'s hand-writing character information based on said first and second hand-written characters only in response to detection of said similarity condition, wherein after input by the user of a hand-written character similar to said user'"'"'s registered hand-writing character information, the input hand-written character is translated into said desired block type character.

9. An information processing method according to claim 8, including the step of displaying each of said hand-written characters on a display means in a real time manner, as a user inputs them.

10. An information processing method according to claim 8, wherein the hand-written characters are input by writing with a pen means on a tablet.

11. An information processing apparatus using a handwriting character recognition function comprising:

a) input means having pen means and a tablet for inputting handwriting trace information by a user;

b) selecting means for selecting a desired block type character as an object of said handwriting trace information, said block type character corresponding to said handwriting trace information according to said handwriting character recognition function;

c) detecting means for detecting a similarity condition between said first trace information input by said input means and a second trace information;

d) registering means for registering said user'"'"'s trace information based only on said first and second trace information in response to said detecting means;

after that when said user inputs handwriting trace information similar to said user trace information, the input information is translated to said desired block type character;

e) display means disposed under said tablet whereby an image on said display means is shown through said tablet;

f) said trace information is displayed real-time on said display means when user inputs said trace information;

g) said apparatus has a user trace information registering mode which is selected when a registering window is opened;

h) said registering window has a first area for displaying said desired block type character information and a second area adjacent to said first area for inputting said trace information by using said pen means; and

i) said registering window has a third area which is displayed for a block type character which is already registered.
