  Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same parts and components are denoted by the same reference numerals. Their names and functions are also the same.

<Device configuration>
FIG. 1 is a diagram illustrating a specific example of a configuration of a mobile terminal 100 as a search device according to the present embodiment. The portable terminal 100 may be a portable device having a touch panel, and examples thereof include a mobile phone having a touch panel, a book display device, an electronic dictionary, and a small PC (personal computer).

  Referring to FIG. 1, a mobile terminal 100 includes a CPU (Central Processing Unit) 10 that is an arithmetic device for controlling the whole, a ROM (Read Only Memory) 11 for storing programs executed by the CPU 10, and the like. And a control unit 13 having a RAM (Random Access Memory) 12 for functioning as a work area when the CPU 10 executes the program, a storage unit 14 composed of a memory, etc., and contents controlled by the control unit It includes a display unit 15 for displaying and a touch panel 17 having an input unit 16 for receiving input from the user.

  The storage unit 14 includes a phone book database 141 for storing phone book data and a dictionary database 142 for storing dictionary data as information including text having a headword of text. The text here includes not only characters but also numbers and symbols. Moreover, the language of this character is not limited to a specific language, and may not be a single language.

  The touch panel 17 is configured by overlapping a display device such as a liquid crystal display device and a position indicating device such as an optical touch panel or a capacitive touch panel, and displays an operation screen to specify an indicated position on the operation screen. CPU10 displays an operation screen on a touchscreen based on the data for displaying the screen memorize | stored beforehand.

<Overview of operation>
FIG. 2 is a diagram showing a flow of a search operation when searching for a headword composed of information text including text such as phone book data and dictionary data stored in the storage unit 14 in the mobile terminal 100. It is. 3 to 11 are diagrams showing specific examples of display screens at the time of search. The control at the time of the search with the portable terminal 100 is demonstrated using these figures. Here, as a specific example, a search operation in which a list of phone book data stored in the phone book database 141 is displayed and a name character as a heading is designated to search the phone book data will be described as an example. For example, the same applies to dictionary data.

  Referring to FIG. 2, when a search operation is started, a search bar presenting candidate characters to be designated is displayed as an initial screen overlaid on the list of phone book data (# 1). FIG. 3 is a diagram showing a specific example of the initial screen. In FIG. 3, as an example, a search bar in which alphabets are arranged from top to bottom in the order of A to Z as character candidates in a line in the vertical direction is shown, but the display direction of the search bar, The order and position of the displayed characters and the content of the displayed characters (alphabet, Japanese, etc.) are not limited to this direction. That is, as another example, Japanese may be displayed in the order of 50 tones or numerical values may be displayed. Moreover, it is not limited to the example of displaying in the form of a single row of bars, and may be displayed in a predetermined area. Some displays may be omitted depending on the size of the displayable area. In the following examples, all states are collectively expressed as a “search bar”.

  Further, a search bar number is given to the search bar as information indicating the position of the designated character in the character string as the search key, and is displayed together with the search bar. In the following description, a position in a character string as a search key for a character to be designated is referred to as “character position”, and represents the order from the beginning of the character string that is used as a search key.

  In the initial screen, “1” is displayed as the search bar number in order to designate the first character of the character string as the search key. In the example of FIG. 3, the search bar number “1” is displayed above the search bar.

  In order to specify the first character as a search key, the position of the first character on the search bar displayed on the initial screen is touched (# 2). When this touch is detected, the character is determined as the first character of the search key, and the display screen transitions from the initial screen to the second screen for designating the second character (# 3).

  FIG. 4 shows an example in which the letter “K” on the search bar on the initial screen is touched. When it is detected that the character “K” is touched, the headword is searched using the character “K” as the search key, assuming that the character “K” is designated as the first character of the search key, and the phone book data. Transition to a list displayed from the phone book data starting with “K”.

  FIG. 5 is a diagram illustrating a specific example of the second screen. Referring to FIG. 5, on the second screen, which is a screen for designating the second character, a search bar is superimposed on the display of the list of phone book data (starting from character “K”) displayed in # 2 above. And a search bar number “2” indicating that the designated character is the second character.

  In order to designate the second character as the search key, the position of the character as the second character on the search bar displayed on the second screen is touched (# 4). When this touch is detected, the character is determined as the second character of the search key, and the display screen changes from the initial screen to the third screen for designating the third character (# 5).

  FIG. 6 shows an example in which the letter “I” on the search bar on the second screen is touched. When it is detected that the character “I” has been touched, the character string “KI” in which the previously specified characters are arranged in order is searched as if the character “I” was specified as the second character of the search key. A headword is searched as a key, and the list of the phone book data transitions to that displayed from the phone book data starting with “KI”.

  FIG. 7 is a diagram showing a specific example of the third screen. Referring to FIG. 7, on the third screen, which is a screen for designating the third character, a search bar is superimposed on the display of the list of phonebook data (starting from character “KI”) displayed in # 4 above. And a search bar number “3” indicating that the designated character is the third character.

  In order to designate the third character as the search key, the position of the third character on the search bar displayed on the third screen is touched (# 6). When this touch is detected, the character is determined as the third character of the search key. Thereafter, each time a character is determined, the screen is switched to a screen for designating the next character in which a search bar is displayed together with a search bar number indicating a character position to be designated next.

  FIG. 8 shows an example in which the letter “M” on the search bar on the third screen is touched. When it is detected that the character “M” has been touched, the character string “KIM” in which the previously designated characters are arranged in order is searched as if the character “M” was designated as the third character of the search key. A headword is searched as a key, and the list of the phone book data transitions to that displayed from the phone book data starting with “KIM”.

  On the other hand, when the character up to the second character is designated and the previously designated character is changed, an operation for redoing the character selection is performed (# 7). As an example of the operation, there is a flick (pay) operation at a position where the search bar number is displayed.

  FIG. 9 shows an example in which up to the second character is designated and an operation for redoing the character selection is performed on the third screen for designating the third character. In this example, a block arrow indicates that a flick operation has been performed, and as an example, a right flick has been performed on the search bar number “3” indicating the third character. In the following explanation, the screen returns to the screen for designating the previous character with one right flick, and the screen for designating the previous character with two times is returned. Return to the screen for specifying the next character. The direction of the flick and the direction of feeding the numbers may be reversed.

  That is, as shown in FIG. 9, when the flick operation is performed once in the right direction on the third screen, the search bar number returns from “3” to “2” as shown in FIG. A screen for redesignating the second character is displayed.

  As another example of the operation for redoing the designation, for example, as shown in FIG. 11, an arrow mark for returning the number to the original position or sending it forward is displayed near the search bar number. In addition, touch and flick to the mark can be mentioned. Further, the search bar number is not limited, and a flick to the search bar itself may be used.

<Functional configuration>
FIG. 12 is a diagram illustrating a specific example of a functional configuration for performing the above-described search operation on the mobile terminal 100. Each function shown in FIG. 12 is mainly formed on the CPU 10 when the CPU 10 of the portable terminal 100 reads out a program stored in the ROM 11 and develops it on the RAM 12 for execution. . However, at least a part may be realized by a hardware configuration such as an electric circuit.

  Referring to FIG. 12, CPU 10 of portable terminal 100 determines an input unit 101 for receiving an input of an operation signal representing a touch position from touch panel 17 and a character as a search key based on the operation signal. A character determination unit 102; a character storage unit 103 for storing the determined character; a character position determination unit 104 for determining a character position for accepting designation; and a character for storing the current character position A position storage unit 105; a deletion unit 108 for deleting characters stored in the character storage unit 103; a search unit 106 for searching for data stored in the storage unit 14 using a search key; and a search bar And a display processing unit 107 for causing the touch panel 17 to display in accordance with the search by the search unit 106.

  The character determination unit 102 refers to the current character position stored in the character position storage unit 105, determines the character based on the touch operation represented by the operation signal, and also determines the character position of the character, It is stored in the character storage unit 103 together with the character position.

  When two or more characters are determined, a character string (text) as a search key is specified by arranging character groups stored in the character storage unit 103 according to the character positions. The search unit 106 performs a search using this text, and inputs the result to the display processing unit 107.

  When the character determining unit 102 determines a character, the character position determining unit 104 advances the current character position by one and determines the character position to receive the next specification. Further, based on the operation signal indicating the flick to the search bar number, the current character position is changed according to the number and direction of the search signal, and the character position to receive the next designation is determined. For example, when the search bar number is flicked twice, the current character position is returned by two, and the character position to receive the next designation is determined. Then, the character position determination unit 104 passes the character position for accepting the next designation to the character position storage unit 105 for storage. Also, the information is input to the display processing unit 107.

  When the character position determination unit 104 determines that the current character position is returned and the character position to receive the next specification is determined, that is, when the already specified character is specified again, the character position determination unit 104 determines the determined character. The position is input to the deletion unit 108. The deletion unit 108 deletes the character determined as the character position after the character position that accepts the next designation from the character storage unit 103. For example, when the character position is moved back two times by two flicks, two characters, the character set last and the character at the previous character position, are deleted from the character storage unit 103. Thereby, the designation of characters after the position returned by the flick is accepted again.

  The display processing unit 107 displays the search result obtained by the search unit 106. Further, the display processing unit 107 displays a search bar with a search bar number superimposed on the display.

<Operation flow>
13 and 14 are flowcharts showing the flow of operations in the mobile terminal 100. 13 and 14, the CPU 10 of the mobile terminal 100 reads out a program stored in the ROM 11, develops it on the RAM 12, executes it, and exhibits the functions shown in FIG. 12. Is realized.

  Referring to FIG. 13, when the search operation is started, in step S101, CPU 10 initializes variable N representing the number of characters +1 already specified as initial value 1 and initializing variable M representing the number of the search bar as initialization processing. Value 1 is assumed. The variable M can take a value from 1 to N. As long as the search bar number is not flicked, that is, unless the character is specified again, the value of the variable M is always equal to the value of the variable N.

  In step S <b> 103, the CPU 10 refers to the variable M, determines the search bar number as the variable M, and displays the search bar with the search bar number on the touch panel 17. Then, it waits for an operation on the search bar or the search bar number.

  When an operation on the search bar is detected (YES in step S105 and YES in step S107), CPU 10 compares variable N and variable M stored at that time. As a result, if M <N (YES in step S109), the search bar number is subtracted according to the flick operation to re-designate by the process described later, and therefore in step S111, the CPU 10 changes the designation represented by the variable M. Characters between the character position to be re-determined and the character position finally determined represented by the variable N-1 are deleted, and the variable N is set to the same value as the variable M in step S113. This process corresponds to a process when a character on the search bar is touched after a process when a rightward flick is received, which will be described later.

  On the other hand, if M = N (NO in step S109), steps S111 and S113 are skipped.

  In step S115, the CPU 10 determines the touched character as the Nth character, and in step S117, executes a search process using a character string (text) from the first character to the Nth character and displays the result. To do.

  Thereafter, in step S119, the CPU 10 increments both the variable N and the variable M by 1, and returns the process to step S103. As a result, the display screen displays a search bar for accepting designation of the next character superimposed on the search result in step S117, and the next character position is set as the search bar number for the search bar. The number indicating is attached.

  When the received operation is not an operation for the search bar but an operation for the search bar number (NO in step S107), the CPU 10 determines the flick direction with reference to FIG.

  If it is a rightward flick (YES in step S121), that is, an operation for returning the search bar number by 1 and the variable M is not 1 (YES in step S123), that is, the character position to be accepted is the first. If not, the CPU 10 decrements the variable M by 1 in step S125, and returns the process to step S103. As a result, the number of the displayed search bar number is reduced by one.

  In this case, since it is determined in step S109 that the variable M is smaller than the variable N, that is, the search bar number is smaller than the next value of the number of characters already specified (YES in step S109), the above step After the processing of S111 and S113 is executed and the characters after the return character position among the already specified characters are deleted, the character position to be accepted next is set to match the search bar number, and the subsequent characters Will be accepted.

  If a variable M is 1 when a rightward flick is received with respect to the search bar number (NO in step S123), the character position to be received is the first, and therefore it is not possible to go back any further. . Therefore, the CPU 10 determines that this operation is invalid, and returns the process to step S105.

  On the other hand, when the operation on the search bar number is a flick directed to the left (NO in step S121), that is, an operation for advancing the search bar number returned to the previous position, and the variable M is smaller than the variable N, that is, the variable If N does not match (YES in step S127), in step S129, the CPU 10 increments the variable M by 1, and returns the process to step S103. As a result, the number of the displayed search bar number is incremented by one.

  At this time, if the search bar number is the same as the next value of the number of characters already determined by advancing the search bar number, that is, the character position where the next new character designation is received, the variable M is the variable N And the processing in steps S111 and S113 is skipped.

  Even if the search bar number is advanced, if the search bar number is equal to or less than the value of the number of characters already determined, that is, if the already specified character is to be specified again, the processes of steps S111 and S113 are executed, After the characters after the return character position among the designated characters are deleted, the character position to be received next is set to match the search bar number, and the subsequent character designation is accepted.

  If the variable M matches the variable N when a leftward flick is received for the search bar number (NO in step S127), the received character position is already the latest position, so this position It is not possible to advance to the next character position without specifying the character. Therefore, the CPU 10 determines that this operation is invalid, and returns the process to step S105.

<Effect of Embodiment>
By repeating the above processing in the portable terminal 100, the user can specify characters as search keys in order while referring to the search bar number.

  If you notice that the specified character is wrong while specifying a series of character strings, you can return the specified state up to the character you want to respecify by performing the operation to return the search bar number. , Can be specified again.

  Also, if the search bar number is returned too much when the search bar number is returned, the designated state can be returned to the character to be redesignated by performing the operation of advancing the search bar number, and can be redesignated. Then, designation can be performed again from that position.

  That is, it is possible to start from the position of the character to be redesignated without redesignating all the characters from the beginning, and the operation can be simplified and the search can be performed quickly.

<Modification 1>
In the above example, the search bar is displayed with a search bar number attached. However, as another example, the search bar number is changed to a search bar number indicating the number of characters as shown in FIGS. You may make it display the selected character string.

  That is, in FIG. 15, a search bar for selecting the second character is displayed in a state where “K” is selected as the first character, and the already selected character “K” is presented above the search bar. .

  In FIG. 16, a search bar for selecting the third character is displayed in a state where “I” is selected as the second character, and the selected character “KI” is presented above the search bar. .

  FIG. 17 shows a search bar for selecting the fourth character with “M” selected as the third character, and presents the selected character “KIM” above it. .

  By accepting operations such as touching on already selected characters displayed above the search bar, the character designation is repeated from the selected character position in the same way as the flick operation for the search bar number in the above example. To.

  By being displayed in this way, it is possible to clearly indicate a character that has already been specified to the user, and to easily specify a character that has already been determined by an operation on the display portion from an arbitrary character position.

<Modification 2>
In the above example, every time one character is designated, the search bar number assigned to the search bar is updated to the character position where the next designation is accepted, and only one search bar is displayed. By doing in this way, a display can be simplified and operativity can also be improved. Alternatively, only the search bar on the previous screen may be displayed. By doing so, the next character can be specified while confirming the previously specified character, which may facilitate the operation. The same applies to the following examples.

  However, as another example, instead of displaying the search bar number and updating the number, a search bar may be added and displayed each time a character is designated. In this way, not only the second and subsequent characters can be selected, but when re-designating, the character can be designated without switching to the search bar for the re-designated character position as described above. You can fix it.

  FIG. 18 is a flowchart showing the flow of operations in the portable terminal 100 when receiving designation of characters using a plurality of search bars. FIGS. 19 to 23 are diagrams showing specific examples of display screens at the time of search.

  Referring to FIG. 18, when the search operation is started, in step S201, as initialization processing, CPU 10 sets initial value 1 to variable N indicating the number of characters +1 already specified, and the position of the search bar where the touched character is located. The numerical value stored in the variable M representing is deleted and initialized. The search bar is displayed in order from left to right from the beginning to the end of the character position. Therefore, the variable M is a number representing the position from the left where the search bar is displayed. The variable M can take a value from 1 to N. The value of the variable M is always equal to the value of the variable N unless a search bar with a character already specified is touched, that is, unless the character is specified again.

  In step S203, the CPU 10 displays one search bar for designating the first character as an initial screen. FIG. 19 shows a specific example of the display screen in step S203. In this example, there is no need to attach a search bar number to the search bar.

  When a touch on the search bar is accepted (YES in step S205), in step S207, the CPU 10 sets the value of the variable M as a numerical value representing the position of the search bar where the touched character is located. Then, the variable M and the variable N are compared.

  As a result, if the variable M is equal to the variable N (NO in step S209), that is, if the search bar corresponding to the character position next to the last character already specified is touched, the CPU 10 in step S211. Determines the touched character as the Nth character.

  In order to display the search bar corresponding to the next character position, the CPU 10 slides the display position of the search bar corresponding to the 1st to Nth character positions used so far in step S213 to the left. In step S215, the variable N is incremented by 1, and in step S217, a new search bar for designating the next Nth character is displayed.

  In step S219, the CPU 10 executes a search using the character string designated so far as a search key, and displays the result.

  Steps S211 to S219 correspond to the operation when a new character is designated by touching the search bar for designating the latest character displayed at the right end in this example. That is, as shown in FIG. 20, when the character “K” is touched on the search bar displayed on the screen of FIG. 19, that character is determined as the first character, and FIG. As shown, the display of the search bar used to specify the character “K” is shifted to the left, and the search bar for specifying the next second character is displayed on the right side. At this time, as shown in FIG. 21, the character already specified is displayed in a different display mode from the other characters in the search bar used at that time. In the example of FIG. 21, the frame is displayed surrounded by a frame, but as another example, it may be displayed in a different color, displayed in bold, or displayed with a motion in animation.

  Similarly, as shown in FIG. 22, when the character “I” in the search bar displayed at the right end on the screen of FIG. 21 and used for designating the character at the next character position is touched, the character is changed. Display of the search bar used for designating the character “I” and the search bar used for designating the character “I” as determined as the second character and as shown in FIG. Are shifted to the left, and a search bar for designating the next third character is displayed on the right side.

  By displaying in this way, it is possible to easily check the already designated character on the screen, and the designation of the character becomes easy.

  In this display, when it is desired to redesignate a character that has already been designated, the search bar used for designating the corresponding character may be touched again. For example, in the screen of FIG. 23, when the next character is designated, the character on the search bar on the right end is touched. However, when the designated character “I” is designated again, By touching the search bar displayed at the middle position on the screen 23, the designation of the character “I” is canceled, and the designation of the character from the second character becomes possible again.

  In this case, the variable M representing the touched search bar is smaller than the variable N representing the character position to be designated next (YES in step S209). In this case, in step S221, the CPU 10 cancels the designation of characters already designated after the character position corresponding to the touched search bar. In step S223, the touched character is determined as the Mth character.

  In the above example, when the character “I” is touched on the designated search bar, the touched character is determined as the second character again.

  Further, when the search bar in which the first character “K” is designated is touched, the designation of the characters “K” and “I” is canceled, and the touched character becomes one character again. Then, the second character is designated.

  In order to display the search bar corresponding to the next character position, the CPU 10 deletes the search bar display after the search bar at the character position to be designated next and slides the remaining search bar display to the right in step S225. Let In step S227, the value of variable N is set to the value of variable M + 1.

  When the search bar with the first character “K” is touched, the search bar for designating the third and subsequent characters is deleted and the next second character is designated. With the search bar displayed, slide the display to the right.

  In step S219, the CPU 10 executes a search using the character string designated so far as a search key, and displays the result.

  By displaying in this way, when re-designating a character that has already been designated, it is easy to simply touch the search bar that you want to re-designate without switching the search bar. It is possible to re-specify the character after that.

  As described in the second modification, when a plurality of search bars are displayed, the display of the search results and the display bar may overlap and become difficult to see. Therefore, preferably, the CPU 10 omits the display of the search bar that overlaps the search result, or reduces the density of the part of the search bar that overlaps the display of the search result (that is, the transparency is lower than the other parts of the search bar). May also be high).

  In addition to the search bar, a search box for presenting a character string as a search key may be displayed so that the designation of the character in the search bar and the display of the search box are linked.

  As a first example, as shown in FIG. 24, characters designated using the search bar are presented in the search box in that order, and then a search bar for designating characters is displayed next. May be.

  As a second example, as shown in FIG. 25, characters designated using the search bar are presented in the search box in that order, and the search bar used for character designation so far and the next You may make it display the search bar for designating the character of.

  In the first example, when direct character input to the search box is accepted (in the example of FIG. 24, the character string “KIM”), a search bar for designating the next character may be displayed. Good. Similarly, in the second example, when direct character input to the search box is accepted (in the example of FIG. 24, the character string “KIM”), the next character is designated together with the search bar in which each character is designated. You may make it display the search bar for doing.

  With such a display, the selected character string is clearly shown, and it is possible to use both the search by inputting characters into the search box and the search bar depending on the situation, which is convenient for the user. Will increase. For example, in the example of FIGS. 24 and 25, the search box is searched up to the third character, but since the fourth character is not clear, the search result can be selected by sliding the search bar on the search bar, or up to the fifth character. Although it tried inputting in a search box, in order to search again from the 4th character, it can change a search bar easily.
