Details of the above object and technical configuration of the present invention and the resulting effects thereof will be more clearly understood from the following detailed description based on the accompanying drawings.

First, FIG. 2 is a diagram illustrating an electronic pen system according to an embodiment of the present invention, and FIG. 3 is a block diagram of a mobile communication terminal according to an embodiment of the present invention.

As shown in FIG. 2, the electronic pen system of the present invention recognizes user record information on the mobile communication terminal 10 that is wired or wirelessly connected to the electronic pen 20, and the pad 30. It is composed of an electronic pen 20 to input.

The mobile communication terminal 10 is connected in series with the electronic pen 20 or performs RF or short-range wireless communication, and the recording information generated by the user recording on the pad 30 with the electronic pen 20 is electronically transmitted. When input from the pen 20, the input recording information is converted into text and a specified operation is performed.

Further, in the present invention, the mobile communication terminal 10 performs a spell check by converting the text received from the electronic pen 20 into text, and if there is an error in the spelling result, the electronic pen 20 It transmits to the system, and includes the function of modifying the text input when receiving the information indicating the modification mode and the record information.

In this case, in order to perform a spell check with a minimum of operations, the mobile communication terminal 10 may receive the input mode selection information from the electronic pen 20.

To this end, the electronic pen 20 of the present invention includes a button 21 for selecting an input mode and at least one lamp 22 for displaying an input mode selected by a user, and there is an error in recording information. In this case, the lamp blinks according to a predetermined rule according to the error information received from the mobile communication terminal 10.

In addition, the electronic pen 20 may also provide the button 21 as a button for selecting a modification mode to inform the mobile communication terminal that modifications are being recorded. For example, when recording is performed in a state in which the button is pushed, it is possible to transmit the information and the recording information indicating that the modification mode is to the mobile communication terminal 10, and may be provided with a separate modification mode selection button.

On the other hand, as shown in FIG. 2, in order to allow the user to distinguish and perform correction input on the pad, the input area of the pad may be divided into a body input area 31 and a correction input area 32.

The mobile communication terminal 10 may recognize the record information to the correction input area 32 as correction information even if it does not receive information indicating that it is a separate correction mode by a method such as coordinate identification. In order for the mobile communication terminal 10 to reflect the recorded contents so that the position to be corrected can be specified, the user selects a portion to be modified from the contents recorded in the body input area 31 by using a circle or the like symbol, The line connecting the part and the correction input area 32 may be further described.

In this case, the mobile communication terminal 10 converts the recording contents into an image, and then identifies the correction position indicated by the line connected to the correction input region 32, thereby text-converting the recording information input to the correction input region 32. The text previously entered at the identified modification position can be modified.

On the other hand, in the present invention, the electronic pen 20 obtains the recording information, the optical coordinate (absolute or relative coordinate) is coded on the optical pad 30, the electronic pen 20 is moved on the pad 30 By performing the reading of the coded optical coordinates can be made, in addition to a variety of methods, such as a method of tracking the position using an ultrasonic wave, a laser method, a micro scanner method, which is not limited in the present invention.

Next, the functional configuration of the mobile communication terminal 10 of the present invention will be described in more detail with reference to FIG. 3.

The electronic pen connection unit 12 is a block that forms a communication path with the electronic pen 20 in a wired or wireless manner, and may be a connection terminal connected in series with the electronic pen 20, and performs wireless communication with the electronic pen 20. It may be a communication module for.

The text converting unit 13 is a block for text-converting the recording information received from the electronic pen 20. When the recording information received from the electronic pen 20 is information for correction, the text converting unit 13 or the correction processing unit ( 16, record information excluding a symbol indicating a correction position and a line connecting to the correction input area 32, etc. are received from the corresponding record information, and the text is converted and returned.

The accuracy verification unit 14 receives the converted text from the text conversion unit 13 or the control unit 11, and checks the spelling of the converted text in a predetermined checking unit using a dictionary stored in the internal memory DB. If there is an error in spelling, the error information is output.

At this time, when a user pushes an input mode selection button 21 provided in the electronic pen 20 and a specific input mode is selected, the electronic pen 20 transmits corresponding input mode selection information to the mobile communication terminal. In this case, the accuracy verification unit 14 minimizes the amount of computation by checking the spelling using a dictionary related to the corresponding input mode among the dictionaries stored in the internal memory.

In this case, the error information is information transmitted to the electronic pen 20, and the electronic pen 20 blinks a lamp provided in the electronic pen 20 according to the received error information so that the user can recognize the error. do. The accuracy verification unit 14 may output error information including the degree of inaccuracy so that the lamp blinking method may be changed according to the degree of inaccuracy.

The lamp flashing controller 15 transmits the error information output from the accuracy verifying unit 14 to the electronic pen 20 so that the flashing of the lamp included in the electronic pen 20 is controlled according to an error. To perform.

The degree of inaccuracy can be divided into, for example, 1. correct, 2. partial inaccuracy, 3. incognition, and the like. Criteria for determining partial inaccuracies or incompatibilities can be implemented in a variety of ways, for example, partial inaccuracies if only one character is wrong in a check unit, or as unrecognizable if two or more characters are incorrect. have.

On the other hand, as a method of changing the flashing method of the lamp may be a method of selecting the number of flashes of the lamp and the color of the lamp according to the degree of inaccuracy, for example, the electronic pen 20 corresponds to the correct information as the error information When the number 1 is received, the green lamp blinks only once, and when the number 2 corresponding to partial inaccuracy is received, the yellow lamp blinks 10 times in succession, and when the number 3 corresponding to the unrecognition is received, the red By blinking the lamp ten times in succession, the user can be specifically aware of the error information.

The user who has confirmed that there is an error in the recorded content by the above process can record the corrected content in the corrected input area 32 on the pad 30, and display the corrected position in the body input area 31. The button 21 can be used to select the correction mode in parallel.

Accordingly, when the correction processing unit 16 receives the information indicating the correction mode and the recording information from the electronic pen 20, the correction processing unit 16 receives the information from the control unit 11 and records the recorded information in the body input area 31 of the corresponding recording information. Based on the identification of the correction position, the content recorded in the correction input area 32 serves to modify the text previously entered at the correction position by text conversion through the text conversion unit 13.

Here, the controller 11 determines whether the record information received from the electronic pen 20 is the correction information, and if it is determined as the correction information, the controller 11 should transmit the record information to the correction processing unit 16. In this case, the method of determining whether the information is corrected information may include receiving information indicating that the correction mode is received from the electronic pen 20, and information recorded in the body input area 31 on the pad without receiving additional information. By determining whether or not the information includes all the information recorded in the correction input area 32, it can be known whether the information is corrected information.
