Abstract

PURPOSE: An efficient pen user interface for an on-line text recognition system is provided to improve the convenience of a user by changing a misunderstanding text into a correct text among probable texts through a simple selection. CONSTITUTION: In the first, the text is represented in blue color on a window desktop screen. If there is no error, the text is automatically inputted into a text input area when a mouse down event occurs. If the text has an error, the user selects the correct text among the probable texts represented by putting a mouse on the misunderstanding text. Also, the user uses the whole desktop screen when writing the text with an electronic pen.

온라인 문자인식시스템을 위한 효율적인 펜 사용자 인터페이스 {Pen User Interface for the Online Character Recognition System}Effective Pen User Interface for Online Character Recognition System

본 발명에서는 전자펜으로 입력한 문자를 인식하여 처리하는 기술로 온라인 문자인식 시스템에 관한 것으로, 인공지능, 패턴인식 분야에 속하는 것이다. 종래의 문자인식시스템에서도 오인식 되었을 경우 후보 문자를 선택하여 처리하는 방법을 사용하고 있지만 기존의 모든 문자인식시스템에서는 후보 문자를 특수한 윈도우에서 후보 문자를 변경하여 해당하는 문서 입력 영역(워드프로세서, 문자열 검색창등 임의의 텍스트 입력 영역)으로 보내는 방식을 사용하고 있으나 본 발명에서는 임의의 텍스트 입력이 가능한 모든 영역에 인식된 결과를 입력시켜 주는 기술임과 동시에 후보 문자를 처리하는 방식이 특수한 창에서 처리되는 것이 아니라 윈도우의 데스크탑 화면에 인식된 결과를 보여주고 인식된 문자(혹은 문자열)을 선택하면 후보 문자가 나타나서 원하는 후보 문자(혹은 문자열)를 선택하여 바로 해당하는 문서 입력 영역에 입력이 되도록하는 발명이다.The present invention relates to an online character recognition system as a technology for recognizing and processing characters input with an electronic pen, and belongs to the field of artificial intelligence and pattern recognition. Conventional character recognition system uses a method of selecting and processing candidate characters when misrecognition is performed. However, all existing character recognition systems change candidate characters in a special window to search the corresponding document input area (word processor, string search). In the present invention, a method for inputting a recognized result in all areas where arbitrary text input is possible and at the same time a method for processing candidate characters is processed in a special window. Rather, it is an invention that displays a recognized result on a desktop screen of a window and selects a recognized character (or string) so that a candidate character appears and selects a desired candidate character (or string) to be directly inputted in the corresponding document input area. .

종래의 기술에서는 전자펜으로 쓴 문자의 오인식된 결과를 수정하여 처리하기 위해서는 새로 쓴다든지, 오인식된 문자 중에서 후보 문자를 선택하여 처리하는 데 있어서 번거롭고 다소 복잡한 과정을 거쳐서 처리하였지만, 본 발명에서는 오인식된 문자에 대하여 후보문자를 선택하여 정인익된 문자로 바꾸어 주는 과정을 대폭 개선하여 효율적이고 사용하기 쉽도록 만들어 주는 발명이다.In the prior art, in order to correct and process a misrecognized result of a character written by an electronic pen, a new writing or a process of selecting and processing a candidate character among misrecognized characters has been processed through a cumbersome and somewhat complicated process. It is an invention that makes it easy and efficient to use by greatly improving the process of selecting candidate letters for characters and converting them into right-handed letters.

온라인 문자인식 시스템에서 무엇보다 중요항 것은 인식률이지만 그에 못지 않은 것이 펜 사용자 인터페이스이다. 본 발명에서는 인식된 문자에 대한 후보 문자를 쉽게 선택하여 오인식 되더라도 후보 문자를 쉽게 선택하여 정인식된 문자로 처리 해 주는 발명이다.The most important factor in an online text recognition system is recognition rate, but nothing else is the pen user interface. In the present invention, even if a candidate character for a recognized character is easily selected and misrecognized, the candidate character is easily selected and processed as a recognized character.

본 발명은 온라인 문자인식시스템에서 후보 문자를 처리함에 있어서, 인식된 결과를 바로 원하는 문서 입력 영역에 넣는 것이 아니라, 1차적으로 윈도우 데스크탑 화면에 인식된 문자(혹은 문자열)를 파란색으로 보여주고 오류가 없으면 마우스 다운 이벤트가 발생했을 때 자동으로 문서 입력영역으로 입력이 되도록 구성되어 있고, 만약 오인식이 되었으면 오인식된 문자(혹은 문자열)를 마우스로 선택하면 후보문자가 나타나도록 하여 쉽게 후보 문자(혹은 문자열)를 선택하여 처리할 수 있도록 구성된 것이다. 또한 전자펜으로 글자를 쓸때 특수한 윈도우 내에서만 사용할 수 있는 제한적인 방법이 아니라 데스크탑 화면 전체 영역에서도 사용할 수 있도록 하여 사용자의 편의성을 최대로 높인 발명이다.According to the present invention, in processing a candidate character in an online character recognition system, the recognized character (or string) is first displayed in blue on the Windows desktop screen and an error is not placed in the desired document input area. If not, it is configured to automatically input to the document input area when a mouse down event occurs. If a misrecognition has been made, selecting a misrecognized character (or character string) with the mouse causes the candidate character to appear so that the candidate character (or character string) is displayed. It is configured to select and process. In addition, the invention is not limited method that can be used only in a special window when writing a letter with the electronic pen, so that it can be used in the entire area of the desktop screen to maximize user convenience.

점차적으로 사람과 컴퓨터간의 사용자 인터페이스 환경이 발달하여 이제는 음성으로 컴퓨터를 제어할 수 있는 시대가 열리고 있다. 또한 오랫동안 필기 문화에 익숙해 있는 사람들에게는 펜 사용자 인터페이스가 무엇보다 중요한 시대가 되었다. 그래서 현재 대부분의 PDA, Pocket PC, H/PC, Palm PC, Web Pad등에서는 문자인식 시스템이 필수적으로 사용되고 있다. 이에 따라 보다 효율적이고 사용하기 쉬운 문자인식시스템이 필요하게 되었다. 본 발명에서는 보다 나은 문자인식시스템을 개발함으로써 사용자의 활용성과 편의성을 높였다.Gradually, the user interface environment between man and computer has been developed, and now the era of controlling a computer by voice is opening. Also, for those who have been used to the writing culture for a long time, the pen user interface has become more important than ever. So, most of PDA, Pocket PC, H / PC, Palm PC, Web Pad, etc. are used as text recognition system. Accordingly, there is a need for a more efficient and easy-to-use character recognition system. In the present invention, by improving the character recognition system to improve the usability and convenience of the user.

Claims (1)

본 발명에서는 온라인 문자인식시스템에서 첫째, 후보 문자를 처리하기 위하여 [대표도]에서 보는 바와 같이, 키보드 입력을 받을 수 있도록 활성화된 윈도우에 1차적으로 인식된 문자의 결과가 파란색으로 나타나게 하여 오인식 되었을 때에는 파란색의 문자(혹은 문자열)을 선택하여 후보문자들 중에서 원하는 문자를 선택하여 쉽게 수정할 수 있도록 하고, 마우스 다운 이벤트가 발생하면 파란색으로 인식된 문자열이 자동으로 원하는 문자 입력 영역으로 입력이 되도록 구성한 것이다. 둘째, [도1]에서 보는 바와 같이 활성화된 윈도우 안에서만 글자를 쓸 수 있는 것이 아니라 데스크탑 화면(컴퓨터 전체 화면)의 임의의 위치에서 자유로운 크기로 글자를 쓸 수 있도록 구성한 것이다. 셋째, 키보드를 사용하여 문자 입력이 가능한 모든 영역(워드프로세서, 문자열 검색 윈도우 등 임의의 문자 입력 영역)에 인식된 결과를 입력시켜 주도록 구성한 것이다.In the present invention, first, in the online character recognition system, as shown in [representative diagram] in order to process candidate characters, the result of the first recognized character appears in blue in a window activated to receive keyboard input, and may be misrecognized. When you select a blue character (or a string), you can easily modify it by selecting the desired character from the candidate characters, and when the mouse down event occurs, the blue recognized string is automatically entered into the desired character input area. . Second, as shown in FIG. 1, not only the letters can be written in the active window but also the letters can be freely written at any position on the desktop screen (the entire computer screen). Third, it is configured to input the recognized result in all the areas where the text can be input (any word input area such as word processor, string search window) using the keyboard.
