Description

  The present invention relates to an input device, and more particularly to an input device that displays a screen including a character input area that accepts selection of a character to be input from a user and a character display area that displays a selected character.

  In recent years, terminal devices such as smartphones equipped with a touch panel are rapidly spreading. Such a terminal device employs a software keyboard for inputting characters. However, since the screen of a smartphone is generally small, there is a problem in that the size of each key included in the software keyboard is reduced, and erroneous input of characters increases.

  In order to solve such a problem, Patent Document 1 discloses an input device that displays only a key whose pressing weight satisfies a predetermined criterion on a screen when a plurality of keys are touched by a user. . However, even if such a technique is used, since the key size remains small, it is difficult to say that the usability has been greatly improved.

  As another input method for improving the usability, a flick input method is widely used. In the flick input method, the user can select a character that the user wants to input with a single operation, so that the character can be input quickly.

  However, even if the flick input method is adopted, erroneous input occurs. In particular, the number of erroneous input increases as the number of characters input at a time increases. In this case, it is necessary for the user to perform an operation of correcting the erroneously input character.

  In this case, in a smartphone where the character display area where the entered characters are displayed and the character input area where the software keyboard is displayed are separated, the task of selecting the characters to be corrected in the character display area, There is a problem that an operation of selecting in the character input area occurs, and the user cannot easily and efficiently correct the character.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an input device that can easily and efficiently correct an input character even if a user inputs a large number of characters at a time. And

  In order to solve the above problem, the first technical means of the present invention provides an input for displaying a screen including a character input area for accepting selection of a character to be input from a user and a character display area for displaying the selected character. A selection receiving unit that accepts a selection of a replacement character to be replaced with a corrected character to be corrected among characters displayed in the character display region; A character display control unit that performs display control to display the replacement character instead of the correction character.

  According to a second technical means of the present invention, in the first technical means, the selection receiving unit corresponds to a slide distance in the slide operation when a user performs a slide operation on the screen in the character display area. The attached character is specified, and the specified character is received as a replacement character selected by the user.

  According to a third technical means of the present invention, in the second technical means, the distance is a slide distance along a predetermined circumference.

  According to a fourth technical means of the present invention, in the second technical means, the distance is a linear distance from a start position to an end position of the slide.

  According to a fifth technical means of the present invention, in the first technical means, the selection receiving unit corresponds to a slide direction in the slide operation when a user performs a slide operation on the screen in the character display area. The attached character is specified, and the specified character is received as a replacement character selected by the user.

  According to the present invention, of the characters displayed in the character display area, the selection of a replacement character to be replaced with the corrected character to be corrected is received from the user in the character display area, and instead of the corrected character displayed in the character display area, Since the display control for displaying the replacement character is performed, the input character can be easily and efficiently corrected even if the user inputs a large number of characters at one time.

It is a figure explaining the correction method of a character. It is a figure explaining another example of the correction method of a character. It is a figure explaining another example of the correction method of a character. It is a flowchart which shows an example of the process sequence of the character input control process which concerns on embodiment of this invention. It is a figure explaining the selection method of the replacement character by a flick input method.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram illustrating an example of a configuration of an input device 10 according to an embodiment of the present invention. Below, although the case where the input device 10 is a smart phone is demonstrated, other input devices provided with character input functions, such as a tablet PC, a touch panel display, and a remote controller of a television, may be sufficient.

  As illustrated in FIG. 1, the input device 10 includes an antenna 11, a wireless communication unit 12, a wired communication unit 13, a touch panel unit 14, a microphone 15, a speaker 16, a storage unit 17, and a control unit 18.

  The antenna 11 is an antenna for performing wireless communication with other devices. The wireless communication unit 12 is a communication device that performs wireless communication with another apparatus via the antenna 11. The wired communication unit 13 is a communication device that performs wired communication with another apparatus via a network cable such as an HDMI cable.

  The touch panel unit 14 is a display / input device that displays information and receives input of information from the user by a user's touch operation. The touch panel unit 14 includes a display unit 14a and a touch sensor unit 14b. The display unit 14a is a display device such as a liquid crystal display. The touch sensor unit 14b is a sensor unit that detects a position on the screen of the display unit 14a touched by the user.

  When the user inputs a character, a character input screen is displayed on the display unit 14a. FIG. 2 is a diagram illustrating an example of the character input screen 20. The character input screen 20 includes a character input area 21, a conversion candidate display area 22, and a character display area 23.

  The character input area 21 is an area in which a software keyboard that accepts selection of characters to be input from the user is displayed. The conversion candidate display area 22 is an area in which conversion candidates for Kana-Kanji conversion are displayed. The character display area 23 is an area where characters selected by the user using the software keyboard, kanji converted from kana by kana-kanji conversion, and the like are displayed.

  FIG. 2 shows a case where character input is performed by a flick input method. In the flick input method, when the “A” key is touched by the user, a character candidate 24 is displayed. And a character is selected by flick operation by the user after that. Here, the flick operation is an operation of sliding a finger in the direction of a character to be input after touching the screen.

  Returning to the description of FIG. 1, the microphone 15 is a microphone for acquiring an audio signal. The speaker 16 is a speaker for outputting sound. The storage unit 17 is a storage device such as a memory or a hard disk device. The storage unit 17 stores dictionary data 17a, replacement character data 17b, and the like.

  The dictionary data 17a is kana-kanji conversion dictionary data. The replacement character data 17b is data indicating the correspondence between the distance that the user slides his / her finger in the character display area 23 and the replacement character. A replacement character is a correct character that replaces an erroneously entered character when correcting the character entered by the user by mistake. A character to be corrected is called a corrected character. The replacement character data 17b is referred to at the time of this correction.

  FIG. 3 is a diagram for explaining a character correction method. FIG. 3 shows an example in which the user inputs a sentence “Let ’s meet up with 13th birthday” and then converts necessary parts into kanji.

  In this sentence, “Aseta” is an error of “Ashita”, and the user needs to correct “Set” to “Sh”. Further, “Tokyo Iki” is an error of “Tokyo Eki”, and the user needs to correct “I” to “E”. Here, “se” and “i” are correction characters, and “shi” and “e” are replacement characters.

  When correcting “Aseta” to “Ashita”, the user selects the corrected character “Se” displayed in the character display area 23 and slides his / her finger along the circumference 30 of a predetermined radius. Characters are assigned to the circumference 30 according to the distance along the circumference 30 from the position of the corrected character.

  For example, in the example of FIG. 3, replacement character candidates “so”, “sa”, “shi”, “ "" (Characters following "se" in the line) are assigned in order. Here, the distance along the circumference 30 from the position of the corrected character is, for example, positive in the clockwise direction and negative in the counterclockwise direction.

  When the user stops sliding his / her finger and releases his / her finger from the screen, the character corresponding to the distance along the circumference 30 from the corrected character “SE” to the position where the finger is released is selected as the replacement character. The

  Even if the position where the user stops sliding the finger is slightly apart from the circumference 30, if the position is within a predetermined distance from the circumference 30, the slide operation is an operation along the circumference 30. The replacement character is selected.

  Here, the circumference 30 and replacement character candidates may or may not be displayed as shown in FIG. 3 as an example. The user can set in advance whether or not to display the circumference 30 and replacement character candidates.

  Also, if the user slides his / her finger to the distance corresponding to the replacement character candidate “So”, “Sa”, “Shi”, or “Su” and keeps that state, it corresponds to that distance The replacement character candidate to be displayed may be displayed instead of the corrected character “SE” in the word “ASETA”. As a result, the user can easily confirm the replacement character candidate currently selected.

  Furthermore, the direction in which the user slides his / her finger may be a clockwise direction or a counterclockwise direction. Even if the user slides his / her finger in the clockwise direction or counterclockwise direction and then slides his / her finger in the opposite direction, the finger is released from the correction character “set”. A character corresponding to the distance along the circumference 30 to the selected position is selected as a replacement character.

  In the example of FIG. 3, when the user slides his / her finger clockwise, the replacement character candidates “so”, “sa”, “shi”, and “su” are sequentially displayed as the finger slide distance increases. When selected and the user slides his / her finger counterclockwise, the replacement character candidates “S”, “S”, “S”, “S” are selected in order as the finger slide distance increases. However, when the user slides his / her finger counterclockwise, the replacement character candidates “so”, “sa”, “ Or “su” may be selected in order.

  In the example of FIG. 3, the user slides his / her finger along the circumference 30, but the position of the circumference 30 is not limited to the position shown in FIG. 3. That is, when the user selects the corrected character “SE” and the user performs a finger slide operation along a predetermined circumference 30 at an arbitrary position in the character display area 23, One of the replacement characters “SO”, “SA”, “SH”, or “SU” may be selected according to the distance along the circumference 30 from the position of the correction character “SE”. .

  The user performs the same operation when correcting “Tokyo” to “Tokyo”. In this case, the circumference 30 includes the replacement character candidates “U”, “E”, “O”, “A” (“A” in the row) according to the distance along the circumference 30 from the correction character “I”. The characters following “I” are assigned in order. When the user slides his / her finger along the circumference 30 to select the replacement character candidate “E” and lifts the finger from the screen, the character “E” is selected as the replacement character.

  Here, the replacement character is determined according to the distance along the circumference 30 from the corrected character, but the replacement character may be determined according to the distance in the linear direction from the corrected character.

  FIG. 4 is a diagram illustrating another example of a character correction method. FIG. 4 shows the same sentence as the sentence shown in FIG. In this correction method, the user selects the correction character “SE” displayed in the character display area 23 and slides the finger in an arbitrary direction.

  FIG. 4 shows a concentric circle 31 centered on the corrected character “SE”. In each area divided by the concentric circles 31, the characters “SO”, “SA”, “SH”, “SU”, “SE” that are candidates for replacement characters according to the straight line distance from the position of the corrected character. Are assigned in order. When the user stops sliding his / her finger and releases his / her finger from the screen, the character corresponding to the straight line distance from the corrected character “SE” to the position where the finger is released is selected as the replacement character.

  Here, the concentric circles 31 and the replacement character candidates may or may not be displayed. The user can set in advance whether or not to display the concentric circle 31 and replacement character candidates.

  In addition, when the user slides the finger to the distance corresponding to the replacement character candidates “so”, “sa”, “shi”, “su”, or “se” and maintains the state, The replacement character candidate corresponding to the distance may be displayed in place of the corrected character “SE” in the word “ASSETA”. As a result, the user can easily confirm the replacement character candidate currently selected.

  The user performs the same operation when correcting “Tokyo” to “Tokyo”. In this case, in each area divided by the concentric circles 31, the characters “U”, “E”, “O”, “A” that are candidates for replacement characters according to the straight line distance from the position of the correction character “I”. , “I” are assigned in order. When the user slides the finger to select the replacement character candidate “e” and lifts the finger from the screen, the character “e” is selected as the replacement character.

  3 and 4, the case where the replacement character is selected according to the distance from the corrected character along the circumference 30 or the distance in the linear direction has been described. A replacement character may be selected accordingly.

  FIG. 5 is a diagram for explaining still another example of the character correction method. FIG. 5 shows the same sentence as the sentences shown in FIGS. 3 and 4. In this correction method, the user selects the correction character “SE” displayed in the character display area 23 and slides the finger in an arbitrary direction.

  FIG. 5 shows a locus 32 in which the user slides his / her finger. In this locus 32, every time the distance that the user slides the finger from the position of the correction character “se” exceeds a certain distance, the characters “so”, “sa”, “shi”, “ "" And "se" are assigned in order (FIG. 5 does not show the characters "su" and "se").

  When the user stops sliding his / her finger and releases his / her finger from the screen, the character corresponding to the distance the user has slid his / her finger to the position where the finger is released from the corrected character “SE” (in the example of FIG. 5). The character “shi”) is selected as the replacement character.

  Here, the locus 32 and the candidate for the replacement character may or may not be displayed. The user can set in advance whether or not to display the trajectory 32 and replacement character candidates.

  In addition, when the user slides the finger to the distance corresponding to the replacement character candidates “so”, “sa”, “shi”, “su”, or “se” and maintains the state, The replacement character candidate corresponding to the distance may be displayed in place of the corrected character “SE” in the word “ASSETA”. As a result, the user can easily confirm the replacement character candidate currently selected.

  The user performs the same operation when correcting “Tokyo” to “Tokyo”. In this case, in the locus 32 where the user slides his / her finger, the characters “U”, “E”, “O”, “A”, which are candidates for replacement characters according to the distance from the position of the correction character “I”, “I” is assigned in order. When the user slides the finger to select the replacement character candidate “e” and lifts the finger from the screen, the character “e” is selected as the replacement character.

  Returning to the description of FIG. 1, the control unit 18 is a control device such as a CPU (Central Processing Unit) that controls each unit of the input device 10. The control unit 18 includes a communication control unit 18a, a call control unit 18b, and a character input control unit 18c.

  The selection receiving unit 18d explained in FIG. 3, FIG. 4, or FIG. 5 in the character display area 23 how to select the replacement character to be replaced with the corrected character to be corrected among the characters displayed in the character display area 23. It is a processing part received from a user by such a method.

  The kana-kanji conversion processing unit 18 e is a processing unit that performs a process of converting kana to kanji with reference to the dictionary data 17 a stored in the storage unit 17.

  The character display control unit 18f is a processing unit that controls display of input characters on the display unit 14a. Specifically, the character display control unit 18f displays characters in the character display area 23, displays selected replacement characters in place of the corrected characters displayed in the character display area 23, or is converted from kana. Controls the process of displaying kanji characters instead of kana.

  Next, a processing procedure of character input control processing according to the embodiment of the present invention will be described. FIG. 6 is a flowchart showing an example of the processing procedure of the character input control processing according to the embodiment of the present invention.

  First, the touch sensor unit 14b of the input device 10 accepts a character input operation by the user in the character input area 21 (step S101). And the display part 14a displays the input character on the character display area 23 (step S102). Thereafter, the selection receiving unit 18d determines whether or not an instruction to convert kana into kanji has been received from the user via the touch sensor unit 14b (step S103).

  When the selection receiving unit 18d receives an instruction to convert kana into kanji from the user (YES in step S103), the kana-kanji conversion processing unit 18e executes processing for converting kana into kanji (step S107). And the character display control part 18f displays on the display part 14a the character string converted into the kanji (step S108). Thereafter, the character input control process ends.

  In step S103, when the selection receiving unit 18d has not received an instruction from the user to convert kana into kanji (NO in step S103), the selection receiving unit 18d includes the characters displayed in the character display area 23. It is determined whether or not designation of a correction character has been received from the user (step S104).

  When the designation of the corrected character is not received from the user (NO in step S104), the processing after step S101 is continued. When the designation of the corrected character is received from the user (YES in step S104), the selection receiving unit 18d performs the replacement character in the character display area 23 by the method described in FIG. 3, FIG. 4, or FIG. Is selected (step S105).

  Then, the character display control unit 18f displays a replacement character instead of the corrected character in the character display area 23 (step S106). Thereafter, the processing after step S103 is continued.

  In the above embodiment, as described with reference to FIGS. 3, 4, and 5, the replacement character is selected based on the distance that the user slides the finger. However, based on the flick input method, That is, it may be performed based on the direction in which the user slides his / her finger.

  FIG. 7 is a diagram for explaining a replacement character selection method by the flick input method. FIG. 7 shows the same sentence as that shown in FIGS. 3, 4, and 5. In this selection method, when the user touches the character “SE” displayed in the character display area 23, the selection receiving unit 18d receives the character as a corrected character. Then, the character display control unit 18f displays selectable replacement character candidates 33.

  Then, when the user slides his / her finger, the selection receiving unit 18d selects a character corresponding to the direction in which the user has slid his / her finger among the replacement character candidates 33 as the replacement character. In the example of FIG. 7, when changing the correction character “se” to the replacement character “shi”, the user touches the character “se” displayed in the character display area 23 and then slides his / her finger to the left.

  Then, in the replacement character candidate 33, the character “shi” in the left direction as viewed from the character “sa” in the center is selected as the replacement character. If the user touches the character “SE” displayed in the character display area 23 and then lifts the finger off the screen without sliding the finger, the character “SA” is selected as the replacement character.

  Thereafter, the character display control unit 18 f displays the selected replacement character “shi” instead of the corrected character “se” in the character display area 23.

  In the example of FIG. 7, selectable replacement character candidates 33 are displayed, but may not be displayed. The user can set in advance whether or not to display a selectable replacement character candidate 33.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and corrections can be made without departing from the gist of the present invention. For example, in the above-described embodiment, the touch sensor unit 14b detects the touch of the user's finger and receives the selection of the character. However, the touch sensor unit 14b detects the touch by a pointing device such as a stylus pen and receives the selection of the character. It is good.
