Abstract

A method and apparatus for receiving strokes of electronic ink in more than one language is provided. An input device is used to enter at least one stroke of electronic ink into a processing device. The processing device stores a language indication associated with the electronic ink, such that the language indication provides a way to associate a handwriting recognizer with the ink. The user may change the language or recognizer associated with the ink by flipping over a pen and using another tip of the pen or may use another pen or other input device. Aspects of the described system and method accommodate various optional interfaces to associate a pen tip or click of a button to one or more languages. Other aspects of the system and method include language switching of a displayed software keyboard when a pen input device is within a predetermined distance from a display.

Claims

1. A process performed in a stylus-based computer system for receiving handwritten information input by a user via a stylus and an input screen, the process comprising:

inputting handwritten information by the user on a first portion of the input screen using a first pen tip of the stylus, the handwritten information on the first portion of the input screen to be recognized according to a first mode of recognizing handwritten input;

detecting at least one of;

the user switching from the first pen tip of the stylus to a second pen tip for inputting handwritten information, the second pen tip being associated with a second mode of recognizing handwritten input; and

the user inputting an instruction to switch from the first mode of recognizing handwritten information to the second mode;

in response to the detecting, switching the input screen from a first input mode associated with the first mode of recognizing handwritten input to second input mode to provide a second portion of the input screen associated with the second mode of recognizing handwritten input, such that the first and second portions of the input screen are concurrently configured according to different input modes; and

inputting handwritten information by the user on the second portion of the input screen using the stylus, the handwritten information on the second portion to be recognized according to the second mode of recognizing handwritten input,

wherein one of the first and second modes of recognizing handwritten input corresponds to character-based recognition, and the other of the first and second modes of recognizing handwritten input corresponds to word-based recognition, and

one of the first and second portions is configured according to boxed input mode and the other of the first and second portions of the input screen is configured according to line input mode.

2. The process according to claim 1, further comprising:

performing character-based recognition on the handwritten information inputted on the portion of the input screen configured in accordance with the boxed input mode; and

performing word-based recognition on the handwritten information inputted on the portion of the input screen configured in accordance with the lined input mode.

3. The process according to claim 2, wherein said inputting the handwritten information in said first portion of the input screen is performed at least in part via a correction user interface.

4. The process according to claim 2, wherein inputting the handwritten information in said second portion of the input screen is performed at least in part via a correction user interface.

5. The process according to claim 1, further comprising receiving user selection of a language and associated input mode to be mapped to each of the first and second pen tips of the stylus.

6. The process according to claim 1, wherein said detecting step includes receiving a user selection of a language and associated input mode to be mapped to the second portion of the input screen.

7. The process according to claim 1,

wherein a first language is associated with the first mode of recognizing handwritten input,

wherein a second language is associated with the second mode of recognizing handwritten input,

the process further comprising:

performing recognition on the handwritten information inputted on the first portion of the input screen based on the first language; and

performing recognition on the handwritten information inputted on the second portion of the input screen based on the second language.

8. A stylus-based computer system comprising:

a user interface including a stylus and an input screen for receiving handwritten information from a user, wherein handwritten information is input by the user on a first portion of the input screen using a first pen tip of the stylus, and the handwritten information on the first portion of the input screen is to be recognized according to a first mode of recognizing handwritten input; and

a processor configured to;

detect at least one of;

the user switching from the first pen tip of the stylus to a second pen tip for inputting handwritten information, the second pen tip being associated with a second mode of recognizing handwritten input; and

the user inputting an instruction to switch from the first mode of recognizing handwritten information to the second mode;

in response to the detection, switch the input screen from a first input mode associated with the first mode of recognizing handwritten input to a second input mode associated with the second mode of recognizing handwritten input in order to provide a second portion of the input screen configured according to the second input mode, such that the first and second portions of the input screen are concurrently configured according to different input modes,

wherein handwritten information is input by the user on the second portion of the input screen using the stylus, and the handwritten information on the second portion is to be recognized according to the second mode of recognizing handwritten input,

wherein one of the first and second modes of recognizing handwritten input corresponds to character-based recognition, and the other of the first and second modes of recognizing handwritten input corresponds to word-based recognition, and

one of the first and second portions is configured according to boxed input mode and the other of the first and second portions of the input screen is configured according to line input mode.

9. The system according to claim 8, said processor being configured to display a correction user interface in association with at least one of the first and second portions of the input screen.

10. The system according to claim 9, said processor responsive to user input to operate said correction user interface for said boxed input mode.

11. The system according to claim 9, said processor responsive to user input to operate said correction user interface for said lined input mode.

12. The stylus-based computer system of claim 8, wherein the processor is further configured to:

receive the handwritten information inputted through the user interface on the first portion of the display screen as a first handwritten ink;

perform recognition of the first handwritten ink in accordance with the first mode of recognizing handwritten input;

receive the handwritten information inputted through the user interface on the second portion of the input screen as a second handwritten ink; and

perform recognition of the second handwritten ink in accordance with the second mode of recognizing input.

13. The stylus-based computer system of claim 8,

wherein a first language is associated with the first mode of recognizing handwritten input,

wherein a second language is associated with the second mode of recognizing handwritten input, and

wherein the processor is further configured to:

perform recognition on the handwritten inputted on the first portion of the input screen based on the first language; and

perform recognition on the handwritten information inputted on the second portion of the input screen based on the second language.
