Description

  The present invention relates to a character conversion technique that enables efficient character input to an application or browser such as a mobile terminal such as a smartphone or a personal computer.

  An apparatus having a character input function has a character string predictive conversion function. The predictive conversion function is a function that predicts words and phrases that are supposed to be input thereafter and presents them to the user as a list on the basis of some characters input by the user. With this predictive conversion function, the user can obtain a list of predicted words / phrases simply by inputting some characters. If the desired phrase exists in the list, the phrase can be determined by simply selecting one phrase from the list without inputting the remaining characters (Patent Document 1).

JP 2008-305385 A

  By the way, when one word is selected from the list of predictive conversions, the user may perform an erroneous operation and an incorrect word may be selected and displayed as a fixed word. At this time, it is necessary for the user to perform an operation of erasing an unnecessary character out of a plurality of characters constituting the phrase with the backspace key (BS key) or an operation of inputting a new character.

  As an example, let us consider a case where “Tokyo” is entered and “Tokyo Tower”, “Tokyo Big Sight” and the prediction conversion list are displayed. The user wanted to select “Tokyo Tower”, but selected “Tokyo Big Sight” due to an operation error. In order to correct from “Tokyo Big Sight” to “Tokyo Tower”, it is necessary to delete the six characters “Big Sight” and enter “Tower” instead. At this time, it is necessary to operate the BS key six times when erasing the six characters of “Big Sight”, and this effort impairs usability.

  Accordingly, the present invention provides a technique for improving usability by allowing a user to quickly correct a character string of a word that has been determined in error even if the user has made a mistake in selecting a prediction conversion candidate word. With the goal.

  In order to achieve the above object, the present invention predicts a character string to be input to the input box based on a part of the characters input to the input box and then uses the input box as a list of predictive conversion candidates. A character conversion device having a function of displaying at a different position, wherein when one of the prediction conversion candidate lists displayed at a position different from the input frame is selected, the selected character string of the prediction conversion candidate Is displayed in the input frame, and after the character string of the predictive conversion candidate is displayed in the input frame by the display unit, a delete key for deleting the character of the character string from behind is operated. In this case, a deletion unit that deletes a plurality of characters collectively from the back of the character string is provided.

  In addition, the present invention is a function for predicting a character string input to the input frame after that based on a part of characters input to the input frame and displaying it as a list of predictive conversion candidates at a position different from the input frame. A display means for displaying a character string of the selected prediction conversion candidate in the input frame when one of the displayed list of prediction conversion candidates is selected; Detection means for detecting vibration of the character conversion device, determination means for determining whether or not the detection result of the vibration by the detection means is equal to or greater than a threshold value, and the character string of the predicted conversion candidate is displayed in the input frame by the display means. When the delete key for deleting the character of the character string from behind is operated after being displayed, each time the delete key is operated, the character is deleted one by one from the back, and the display means According After the predictive conversion candidate character string is displayed in the input frame, when the determination unit determines that the detection result of the vibration by the detection unit is greater than or equal to a threshold value, a plurality of characters from the rear of the character string are displayed. And deleting means for deleting all at once.

  ADVANTAGE OF THE INVENTION According to this invention, even when a user mistakes selection of the word of a prediction conversion candidate, the character string of the word / phrase determined in error can be corrected rapidly, and a usability can be aimed at.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a system configuration example of a character conversion device according to the first embodiment of the present invention. In addition, in this embodiment, although a smart phone is illustrated as a character conversion apparatus, it is not limited to this.

  As illustrated in FIG. 1, the character conversion device 10 according to the present embodiment includes a control unit 100, a memory 101, a touch panel 102, a communication unit 103, and a vibration sensor unit 104, and character input from a user via the touch panel 102. In response to this, the entered characters are displayed on the screen.

  The control unit 100 has a predictive conversion function that predicts words that are supposed to be input afterward based on some characters input by the user via the touch panel 102 and presents them to the user as a list. In addition to having a function of generating a screen to be displayed on the touch panel 102, the control unit 100 performs graphics processing for drawing a frame line in the display screen. Further, the control unit 100 combines an input window for inputting characters, a keyboard image, and a user input character as an image, and stores the combined image in the memory 101.

  The control unit 100 temporarily expands programs and data in the memory 101 to control the entire apparatus. The screen displayed on the touch panel 102 is constructed in the memory 101 by the control unit 100. The memory 101 stores, for example, button images and character data used for screen display of the touch panel 102. The memory 101 stores dictionary data used for predictive conversion of characters by the control unit 100 and predictive conversion dictionary data used for predictive conversion.

  The touch panel 102 has two functions of a display unit and an operation unit of the character conversion device 10 and displays a screen generated by the control unit 100. Further, the touch panel 102 has a function of detecting a touch operation by the user and transmitting it to the control unit 100.

  The communication unit 103 transmits information to and from an external device via communication means such as a network, and transmits, for example, characters input on the touch panel 102 to the external device. The vibration sensor unit 104 detects how much the character conversion device 10 is shaking.

  Next, an operation example of the touch panel 102 will be described with reference to FIG. When the user gives an instruction for starting an application on the touch panel 102, the control unit 100 reads a program for starting the application from the memory 101 and starts the application. As shown in FIG. 2, a web browser application screen 202 is displayed on the touch panel 102.

  On the application screen 202 of the web browser, a search key 204 and an input frame 201 for inputting a character to be searched are displayed. When the user touches the input frame 201, the control unit 100 detects this, and stores it in the memory 101 to the user. Build a screen to present. Then, the control unit 100 combines the keyboard image stored in the memory 101 and the background, and displays the keyboard 203 on the touch panel 102. The user inputs a character into the input frame 201 by operating a predetermined key on the keyboard 203.

  Next, the predictive conversion function when a character is input to the input frame 201 by operating the keys of the keyboard 203 will be described with reference to FIG. FIG. 3A shows a state where up to “Tokyo” is entered in the input frame 201 in order to search for “Tokyo Dome”. FIG. 3B shows a state where up to “Tokyo” has been input in the input frame 201 in order to search for “Tokyo Dome”.

  The control unit 100 analyzes the characters input in the input box 201 and collates with the dictionary data stored in the memory 101 to generate a prediction conversion list 301. The generated prediction conversion list 301 is displayed under the input box 201. The screen is synthesized so as to be displayed at the side position and displayed on the touch panel 102.

  In FIG. 3B, for example, “Tokyo Dome”, “Tokyo Olympics”, and “Tokyo Marathon” are displayed as the prediction conversion list 301 in response to the input of “Tokyo”. Here, it is assumed that the user wanted to select “Tokyo Dome” in the prediction conversion list 301, but accidentally selected the “Tokyo Olympics” list 302 as shown in FIG.

  At this time, as shown in FIG. 3D, the input in the input frame 201 is confirmed with the character string “Tokyo Olympics”. Here, in order to correct an input error, if a delete key (not shown) is operated once, a character string “Tokyo” and a predictive conversion before predictive conversion are displayed in the input frame 201 as shown in FIG. The list 301 is redisplayed. That is, the display state is the same as in FIG. Accordingly, the six characters “Olympic” can be deleted in one operation without operating the delete key six times to delete the six characters “Olympic”.

  Next, a process executed by the control unit 100 based on a character input operation to the input frame 201 by the user will be described with reference to FIG. Each process in FIG. 4 is executed by the CPU of the control unit 100 according to a program stored in the memory 101.

  In FIG. 4, in step S <b> 401, the control unit 100 activates a web browser application screen on the touch panel 102, and when the user touches the input frame 201, the control unit 100 initializes the memory 101 to be performed at the start of character input. When the user operates a key on the keyboard 203 to input a character string into the input frame 201 and the character string is confirmed, the control unit 100 proceeds to step S402.

  Here, when the user operates the keys of the keyboard 203 to input “Tokyo Dome” in the input frame 201, first, when “to” is key-inputted, the control unit 100 sets “to” in an unconfirmed state. It is displayed in the input frame 201. Similarly, when “u”, “ki”, “yo”, and “u” are key-inputted, the control unit 100 displays each in an unconfirmed state in the input frame 201.

  At this time, the control unit 100 displays the normal conversion candidate “Tokyo” or “Tokyo” in the input frame 201 from the input “Tokyo”, and the prediction conversion candidate “Tokyo Dome” at the lower position of the input frame 201. , “Tokyo Olympics”, “Tokyo Marathon” list.

  Then, when the user selects and determines the normal conversion candidate “Tokyo” or “Tokyo”, the control unit 100 stores in the memory 101 that the last determined character string is selected from the normal conversion and fixed. To do. In addition, when it is determined in the “Tokyo” state, it is stored in the memory 101 that the character string finally determined is determined in an unconverted state.

  In step S402, the control unit 100 determines whether or not a key input from the user has been accepted. If accepted, the process proceeds to step S403. If not accepted, the process proceeds to step S409.

  In step S409, the control unit 100 determines whether one of the lists of prediction conversion candidates “Tokyo Dome”, “Tokyo Olympics”, and “Tokyo Marathon” has been selected by the user's touch operation. If one of the prediction conversion candidate lists is selected, the control unit 100 proceeds to step S405. If not selected, the control unit 100 determines that the display is confirmed with the character string input in the input frame 201 and ends the process. . Here, it is assumed that the user selects, for example, “Tokyo Olympics” from the list of prediction conversion candidates “Tokyo Dome”, “Tokyo Olympics”, and “Tokyo Marathon”, for example.

  In step S405, since the prediction conversion candidate “Tokyo Olympics” has been selected, the control unit 100 displays and confirms “Tokyo Olympics” in the input frame 201. Further, the control unit 100 stores in the memory 101 that the character string that has been finally confirmed is selected from the prediction conversion candidates and has been confirmed, and the process proceeds to step S410.

  In step S <b> 410, the control unit 100 searches the dictionary data stored in the memory 101 for a predictive conversion candidate related to the character string “Tokyo Olympics” displayed in the input frame 201, and moves the lower position of the input frame 201. And the process proceeds to step S411. Here, for example, “Tokyo Olympic Venue”, “Tokyo Olympics 2014”, and the like are displayed at the lower position of the input frame 201.

  In step S411, the control unit 100 determines whether one of the lists of prediction conversion candidates “Tokyo Olympics venue” and “Tokyo Olympics 2014” has been selected by a user's touch operation. The control unit 100 proceeds to step S412 when one of the prediction conversion candidate lists is selected, and returns to step S402 when one is not selected.

  In step S412, the control unit 100 displays and confirms the character string selected in step S411 in the input frame 201, and proceeds to step S413.

  On the other hand, in step S403, the control unit 100 determines whether or not the key input accepted in step S402 is a delete key input. If it is a delete key input, the process proceeds to step S404. The process proceeds to step S408.

  In step S404, the control unit 100 determines whether or not the character string input to the input box 201 is a character string after predictive conversion based on the information stored in the memory 101. The process proceeds to step S406, and if not, the process proceeds to step S407. Here, the character string after the predictive conversion is “Tokyo Olympics”.

  In step S406, the control unit 100 collectively deletes the six characters “Olympic”, which is a break of the noun “Tokyo Olympics”, which is the character string after the predictive conversion, leaving “Tokyo”, and proceeds to step S410. move on. Here, the case of leaving “Tokyo”, which is a noun break, is illustrated, but “Tokyo”, which is the converted character of the portion where the “Kana” input by the user has been completed, may be left. Alternatively, the input state of the unconfirmed “kana” input by the user may be returned to display “Tokyo”. A process for deleting a plurality of characters will be described later.

  In step S410, as described above, the control unit 100 displays “Tokyo Dome”, “Tokyo Olympics”, and “Tokyo Marathon” that can be predicted from “Tokyo” in the input frame 201 as a list of prediction conversion candidates, Proceed to step S411.

  In step S407, the control unit 100 deletes one character from the back of the character string in order to delete the normal conversion candidate character string, the unconfirmed character string, or the non-converted character string, and the process proceeds to step S410.

  In step S308, the control unit 100 executes any one of the following three processes 1) to 3) according to the key input, and proceeds to step S410. That is, 1) When normal key input is performed by the keyboard 203, one character specified by the user is added to the character string displayed in the input frame 201. 2) When a confirmation key (not shown) is operated, an unconfirmed character string displayed in the input frame 201 is confirmed. 3) When the normal conversion key is pressed, normal conversion is performed. (Normal conversion is conversion from “Tokyo” to “Tokyo”.)

  The control unit 100 determines whether or not the search key 204 is operated by the user in step S413 after the series of processing in steps S401 to S412 is completed and the character string displayed in the input frame 201 is determined. Determine. When the search key 204 is operated, the control unit 100 searches the web or image based on the character string determined by the web browser application, and connects to an external device via the network or the like by the communication unit 103. Collect information.

  Next, processing for deleting a plurality of characters will be described with reference to FIGS. FIG. 5 is a diagram for explaining processing when deleting a plurality of Japanese characters. FIG. 6 is a diagram for explaining processing when deleting a plurality of English characters.

  First, referring to FIG. 5, in the case of Japanese, a plurality of characters may be a phrase, or may be a noun and a particle. As shown in FIG. 5A, when the result of the predictive conversion candidate is “Tokyo Olympic venue”, the deletion character string by the operation of the single deletion key is as shown in FIG. Delete the word "Venue", "Olympic", "Tokyo". As shown in FIG. 5 (c), when a particle is included, as shown in FIG. 5 (d), the particle and noun are divided into “town”, “no”, “Tokyo” and the structure of the sentence. Perform deletion. Further, as shown in FIGS. 5 (e) and 5 (f), particles may be grouped with any of the preceding and following words to be deleted.

  Next, referring to FIG. 6, in the case of a foreign language, it is assumed that a plurality of characters are in units of words or phrases. In the case of English, as shown in FIG. 6 (a), “Tokyo Olympics meetingplace” is broken down into words, and as shown in FIG. 6 (b), “place”, “meeting”, “Olympics”, Delete “Tokyo” in units of words. In addition, when an idiom such as “A lot of” in “A lot of pens” shown in FIG. 6C is included, it may be in units of words as shown in FIG. As shown in FIG. 4B, it may be divided into “pens” and “A lot of”.

  The plurality of characters may be a character string composed of a plurality of words. For example, if “Tokyo” is entered and “Tokyo Disneyland location” is selected from the list of prediction conversion candidates, only “Tokyo” corresponding to “Tokyo” entered by the user is left, and multiple “Disneyland locations” The character string of the word may be deleted.

  Thus, the character string presented by the predictive conversion has information on the structure of the word, and a plurality of character strings are determined using the breaks.

  As described above, according to the present embodiment, even when the user makes a mistake in selecting a prediction-converted word / phrase, the character string of the word / phrase that has been determined in error can be quickly corrected, thereby improving usability. be able to.

(Second Embodiment)
Next, a character conversion apparatus according to the second embodiment of the present invention will be described with reference to FIG. Note that portions that overlap or correspond to the first embodiment will be described with reference to the drawings and symbols. In the present embodiment, in the deletion process after the predicted conversion character string is confirmed, the detection result of the vibration sensor unit 104 is used to switch between deletion for each of a plurality of character strings and deletion for each character. Each process in FIG. 7 is executed by the CPU of the control unit 100 according to a program stored in the memory 101.

  In FIG. 7, in step S701, the control unit 100 executes a process for starting deletion of a character string, and proceeds to step S702. Here, the user inputs “Tokyo” in the input frame 201 and selects “Tokyo Olympics” presented by the predictive conversion, but it is assumed that an erroneous input is noticed.

  In step S702, the control unit 100 determines whether or not the delete key has been operated. If the delete key has been operated, the process proceeds to step S705; otherwise, the process proceeds to step S703.

  In step S705, the control unit 100 deletes one character from the latter half of the confirmed character string because the delete key is pressed, and ends the process.

  In step S703, the control unit 100 determines whether or not the detection result of the vibration sensor unit 104 is equal to or greater than a threshold value. If the detection result is equal to or greater than the threshold value, the control unit 100 determines that the character conversion device 10 is shaken, and proceeds to step S704. If not, the process ends.

  In step S704, since the character conversion device 10 has shaken, the control unit 100 collectively deletes the six characters “Olympic” from the rear of the character string “Tokyo Olympics” determined by predictive conversion, and ends the process. .

  Thus, in this embodiment, even if the character string input by predictive conversion is incorrect input, the user can select whether to delete one character at a time or to delete a plurality of characters at once. In the present embodiment, the case where one character is deleted by operating the delete key and plural characters are deleted by vibration detection of the character conversion device 10 is illustrated, but the reverse may be possible. Other configurations and operational effects are the same as those in the first embodiment.

(Third embodiment)
Next, with reference to FIG. 8, the character conversion apparatus which is the 3rd Embodiment of this invention is demonstrated. Note that portions that overlap or correspond to the first embodiment will be described with reference to the drawings and symbols.

The server control unit 700 controls the entire server device 20. The server memory 701 manages predictive conversion dictionary data. Server communication unit 702 is communicably connected to communication unit 103 of character conversion device 10 via a network.

  When the user inputs a character into the input frame 201 of the application screen 202 of the web browser of the character conversion device 10, the input character is transmitted from the communication unit 103 to the server device 20 via the network, and the transmitted input character is the server communication. Received by the unit 702. The server control unit 700 analyzes the received input character, and generates a character string that is predicted to be input thereafter using the dictionary data for prediction conversion in the server memory 701. Then, the server control unit 700 transmits the generated character string from the server communication unit 702 to the communication unit 103 of the character conversion device 10 via the network.

  When the communication unit 103 receives the character string transmitted from the server device 20, the control unit 100 of the character conversion device 10 stores the received character string in the memory 101. Then, the control unit 100 notifies the web browser application that the predicted conversion character string has been acquired from the server device 20. The web browser application receives the prediction conversion result stored in the memory 101, and the control unit 100 combines the prediction conversion character string stored in the memory 101 with the application screen 202 and displays it at the lower position of the input frame 201. To do.

  If the server device 20 has a predictive conversion function, the predictive conversion dictionary data of the server device 20 is continuously updated with characters input by a plurality of client applications. The probability of matching with is high. Since the prediction conversion function of the server device is publicly known, the description thereof is omitted here. Other configurations and operational effects are the same as those in the first embodiment.

  In addition, this invention is not limited to what was illustrated by said each embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.
