Description

  The present invention relates to an information search apparatus, an information search method, and a control program for searching for information such as dictionary information.

  For example, when searching for dictionary information in an electronic dictionary or Web search, etc., when related information is traced and a transition is made to a plurality of search display screens, a “return operation” for returning to the previous screen can be performed. . Then, the “return operation” can be performed many times to display the search display screen retroactively.

  It is a conventional information search apparatus, and it is considered that a plurality of search results that are repeatedly searched are sequentially displayed in accordance with an operation of a “return” button (see, for example, Patent Document 1). .

  In a conventional display control apparatus, when a search is performed by tracing the relationship between contents, it is considered that the traced contents are displayed as a thumbnail as a list (for example, see Patent Document 2).

Since it is determined that the movement of the user touch T has been stopped for a certain period of time (step A7 (Yes)), the search history data is associated with the image data P1s on the search target screen [multiple dictionary jump search screen Ga1]. The operation data registered in the memory 12d (see FIG. 3A) is re-executed, and the actual search target screen [multiple dictionary jump search screen Ga5] is regenerated so as to be operable by the user, and is replaced with the image data P1s. Is displayed (step A9).

  Then, thereafter, processing steps (A) and (B) according to the search operation state on the actual search screens Ga and Gb replaced with the image data Pn moved and displayed on the foreground on the search history image screen Gsh ( C) The process proceeds to (D) and (E). Here, the processing step (C) according to the search operation state in the [multi-dictionary jump search screen Ga5] replaced with the image data P1s. Transition is made (step A10).

  That is, as shown in FIG. 9D (C), a [multiple dictionary jump search screen Ga5] including a headword list area Lm and a preview area vi on the search history image screen Gsh is generated and displayed (step S16). When the headword of the dictionary to which the jump search is made (here, [Seiko Nichikoku] “Uru-Doshi [Year]”) is designated and displayed by default (step S17), the [multiple dictionary jump search screen Ga5] One transition to (blue frame) is confirmed, and the image data P7s of the [multi-dictionary jump search screen Ga5] is associated with the operation data, and the history data (operations) of the search history data memory 12d (see FIG. 3B) Corresponding image) 7 is registered (step S18).

  Further, in the same processing step according to the search operation state in the [multi-dictionary jump search screen Ga5], as shown in FIG. 9E (A), another dictionary entry word (here, [New ○ English University] When “Uru Udoshi [Year]”) is touched by the user and designated (h) (step S17), a transition to the [multiple dictionary jump search screen Ga6] (blue frame) is confirmed and the [multiple dictionaries]. The image data P8s on the jump search screen Ga6] is associated with the motion data and registered as history data (operation-corresponding image) 8 in the search history data memory 12d (see FIG. 3B) (step S18).

  9D (C) and 9E (A), the actual search screen [multiple dictionary jump search screen Ga5] (blue frame) is generated and displayed on the search history image screen Gsh. Then, the display process (step A1) of the search history icon HS that shifts to the search history display control process (step SA) is not executed. Further, in this state, when the user registration history icon RH is touched by the user T, the process proceeds to processing after step A16 of the search history display control processing (step SA).

  Then, as shown in FIG. 9E (B), the search history image screen Gsh is cancelled, and an explanation corresponding to the entry word [New ○ English University] “Uru Udoshi [Year]” in the selected dictionary is made. Information is read from the jump destination dictionary [New English Dictionary] and displayed on the touch panel display 17 as [Explanation Information Display Screen Gb3] (red frame) (step S19).

  As a result, the contents of the search screens Ga1, Gb1,... At each search stage in the registered search history can be quickly selected and confirmed, and another search operation can be performed again from the selected search stage. .

  When one transition to [explanation information display screen Gb3] (red frame) corresponding to this headword [New ○ English University] “Uru Udoshi [Year]” is confirmed, the image data of the [explanation information display screen Gb3] P9r is associated with the operation data and registered as history data (operation-corresponding image) 9 in the search history data memory 12d (see FIG. 3B) (step S20).

  Then, the process proceeds to the search history display control process in FIG. 8 (step SA), and the history data up to this time (here, history data 1, 2, 3, 4, 5, 6, 7, 8 is stored in the search history data memory 12d. , 9) of the search screen image data (here, search screen Ga1, Gb1, Ga2, Ga3, Ga4, Gb2, Ga5, Ga6, Gb3 image data P1s, P2r, P3s, P4s, P5s, P6r, P7s, P8s, P9r) are arranged and displayed on the lower left of the touch panel display unit 17 as a search history icon HS in which the image data is reduced (step A1).

  Here, using the search history data (12d) according to the series of information search control processing, for example, any one of the search screens is associated with the text that is the basis of the search history and the character position thereof, and the user When registration is desired, when the search history icon HS displayed at the lower left of the touch panel display unit 17 is touched by the user (step A2 (Yes)), the search history data memory 12d (see FIGS. 3A and 3B). The image data P1s to P9r of the search screens Ga1 to Gb3 registered as the history data 1 to 9 up to this time are read, and as shown in FIG. 9E (C), the image data P1s to P9r are sequentially horizontal. The search history image screen Gsh arranged in a list is displayed on the touch panel display unit 17 (step A3).

  At this time, a history registration icon RH for setting to the search history user registration mode is displayed on the lower left of the touch panel display unit 17 (step A3a).

  In the search history image screen Gsh displayed on the touch panel display unit 17, as shown in FIGS. 9F (A) and (B), when the image data Pn of any search screen is touched by the user (step A4 (Yes )), The touched image data Pn is moved to the forefront and displayed (step A5).

  When the user touch T on the search history image screen Gsh is moved in the left-right direction and the image data Pn of another search screen is newly touched (step A6 (Yes)), FIG. 9F (B) As shown in FIG. 4, when it is determined that the user touch T has been moved in the diagonally downward direction LD (step A14 (Yes)), among the image data P1s to P9r of the search screens Ga1 to Gb3, the search result screen ( Red frame display) Only the image data P2r, P6r, P9r of Gb1, Gb2, Gb3 are displayed in a list (step A15).

  As a result, not only can the contents of the search screens Ga1, Gb1,... At each search stage in the registered search history be quickly selected and confirmed, but the search result screens Gb1, Gb2,. You can select and check only the contents more quickly.

  Then, as shown in FIG. 9F (C), in the search history image screen Gsh in which only the image data P2r, P6r, P9r of the search result screen (displayed in red frame) Gb1, Gb2, Gb3 is displayed as a list, a history registration icon When the RH is touched by the user T1 (step A16 (Yes)), the search history user registration mode is set.

  Here, among the three search result screens (red frame display) Gb1, Gb2, Gb3 of the image data P2r, P6r, P9r, for example, two search result screens (red frame display) Gb1, Gb3 image data P2r, P9r. Are sequentially designated by the user touches T2 and T3, and when it is determined that a certain time has passed or an execution operation has been performed (steps A17 and A18 (Yes)), the user touches T2 and T3 The two search history images P2r and P9r specified by the above correspond to the text data name (text 1) and the character position (page P1, line L5, digit range 2nd to 3rd characters) that are the basis of a series of search history. Then, it is registered in the user registration history data memory 12e (see FIGS. 4A and 4B) (step A19).

  As a result, the image data P1, P2,... Of a series of search screens including the search target screens Ga1, Ga2,... And the search result screens Gb1, Gb2,. The image data Pn on the search target screen Gan or the search result screen Gbn desired by the user can be quickly selected and registered.

  Thereafter, as shown in FIG. 9G (A), arbitrary text data (for example, text 1 “Year and Olympics”) is selected from the text data 1, 2,... Stored in the text data memory 12c. When it is selected again and displayed on the touch panel display unit 17 as the text viewer screen Gtv (step S23), the character position (P1, L5) registered in the user registration history data memory 12e for the displayed text data 1 is displayed. , 2nd to 3rd characters) are included (step S24 (Yes)), a blue underline L is added to the character “Year” at that character position for identification, and adjacent to the character position. Then, the user registration history icon DRH is displayed (step S25).

  Thereby, the user can easily recognize that the search information has been registered in the past with respect to the text “Year and Year” of the text data 1 “Year and Olympics” displayed on the text viewer screen Gtv.

  Here, when it is determined that the text display position is moved by, for example, a vertical user touch (not shown) on the text viewer screen Gtv (step S27 (Yes)), the movement operation is performed. The text data is displayed again from the corresponding position (step S23).

  Then, it is determined again whether or not the character position registered in the user registration history data memory 12e is included in the range of the re-displayed text data (step S24).

  On the other hand, as shown in FIG. 9G (A), when the user registration history icon DRH displayed adjacent to the character “Year” on the text viewer screen Gtv is touched by the user (step S28 (Yes)), As shown in FIG. 9G (B), two search results registered in the user registration history data memory 12e in association with the character position (P1, L5, second to third characters) of the character “Year” The image data P2r and P9r of the screens (red frame display) Gb1 and Gb3 are read, and a registered image window GR in which the image data P2r and P9r are partially overlapped is displayed (step S29).

  Here, as shown in FIG. 9G (C), when the registered image window GR is touched by the user (step S30 (Yes)), each search result screen (red) displayed in a partially overlapped state is displayed. (Frame Display) A registered image window GR in which the image data P2r and P9r of Gb1 and Gb3 are changed to a vertically arranged state is displayed (step S31).

  Further, when the registered image window GR is touched by the user T (step S32 (Yes)), the images of the search result screens (red frame display) Gb1 and Gb3 that are displayed in a vertically arranged state are displayed. The registered image window GR in which the data P2r and P9r are partially changed again is displayed (step S29).

  Thereafter, when it is determined that an operation for closing the registered image window GR is performed in accordance with a user operation (step S33 / S34 (Yes)), the text is again displayed as shown in FIG. 9G (A). The display returns to the display state of the text viewer screen Gtv on which the data 1 is displayed (step S23).

  As a result, the user can not only easily recognize that the search data has been registered in the past for the text “Year and Olympics” of the text data 1 “Year and Olympics” displayed on the text viewer screen Gtv. The registered search result screens (red frame display) Gb1 and Gb3 image data P2r and P9r can be immediately displayed in a window in a desired display form for confirmation.

(Information search control processing from dictionary search mode)
On the other hand, after the dictionary search mode is selected in step S1 (step S1 (Yes)), if any dictionary stored in the dictionary database 12b is selected, the search corresponding to the selected dictionary is performed. [Search screen Ga1] (not shown) having a word input area, a headword list area Lm searched for a match with the input search word, and a preview area vi of explanation information corresponding to the specified headword It is displayed on the touch panel display unit 17 (step S2).

  Here, when a desired search word is input by handwriting using the empty area of the touch panel display unit 17 (step S3), the input handwritten character is recognized, and the search word of the [search screen Ga1] is displayed. It is displayed in the input area (step S4).

  When a search is instructed according to a user operation, or when a certain period of time has elapsed after the handwritten character is input, a heading corresponding to the search word is selected for the selected dictionary (for example, [multiple dictionaries]). The words are searched and displayed in a list in the headword list area Lm (step S5).

  Then, the first headword displayed in the list in the headword list area Lm is highlighted and designated and displayed h, and the explanation information of the headword that is designated and displayed is read from the corresponding dictionary and displayed in the preview area vi. (Step S6).

  In this way, when one transition on the [coming search screen Ga1] is confirmed, the search word is input, the headword is designated and displayed, and the explanation information is preview displayed on the [coming search screen Ga1]. The image data P1 is associated with the operation data and registered as history data (operation-corresponding image) 1 in the search history data memory 12d (step S7).

  Then, the process proceeds to the search history display control process in FIG. 8 (step SA), and the search screen image data (here, only history data 1) registered in the search history data memory 12d as the current history data (here, history data 1 only). Then, the image data P1s) of the search screen Ga1 are arranged, and the image data is displayed as a reduced search history icon HS on the lower left of the touch panel display unit 17 (Steps A1, A2 (No) → Return).

  Thereafter, when any headword displayed in the headword list area Lm is touched and designated by the user touch T in the [search screen Ga1], the designated display is displayed (step S8). The description information of the headword is read from the corresponding dictionary and displayed in the preview area vi (step S9).

  Then, the headword that has been designated and displayed when the user touch T is no longer detected in the headword list area Lm is selected (step S10), and the explanation information corresponding to the selected headword is [description information]. Displayed on the touch panel display unit 17 as a display screen Gb1] (not shown) (step S11).

  Thus, when one transition to the [description information display screen Gb1] is confirmed, the image data P2r of the [description information display screen Gb1] corresponding to the entry word in the dictionary selected as the search target is the operation data. Correspondingly, it is registered as history data (operation corresponding image) 2 in the search history data memory 12d (step S12).

  Then, the process proceeds to the search history display control process in FIG. 8 (step SA), and the search screen image data (in this case, history data 1 and 2) registered in the search history data memory 12d as the history data up to this time (here, history data 1 and 2). Here, the image data P1s and P2r of the search screens Ga1 and Gb1 are arranged, and the image data is displayed on the lower left of the touch panel display unit 17 as a reduced search history icon HS (Steps A1 and A2 (No) → return).

  In the [description information display screen Gb1] corresponding to the selected headword, a character to be subjected to jump search is displayed on the [description information display screen Ga2] (not shown) in which the user touch T is specified and displayed. When one transition is confirmed (step S13 (Yes)), the image data P3s of the [description information display screen Ga2] is associated with the operation data, and the history data (operation corresponding image) 3 of the search history data memory 12d is obtained. Registered (step S14).

  Then, the process proceeds to the search history display control process in FIG. 8 (step SA), and the image of the search screen registered as the history data up to this time (here, history data 1, 2, 3) in the search history data memory 12d. Data (here, the image data P1s, P2r, and P3s of the search screens Ga1, Gb1, and Ga2) are arranged and displayed on the lower left of the touch panel display unit 17 as a search history icon HS in which the image data is reduced (step A1). , A2 (No) → Return).

  Here, when it is determined that the user touch T with respect to the target character for the jump search is not detected in the [description information display screen Ga2] (step S15 (Yes)), the jump search target dictionary is used as the target. [Jump destination headword selection screen Ga3] (not shown) in which a headword list area Lm searched for the search target character and a headword explanation information preview area vi is arranged is displayed on the touch panel display unit 17 (step S16). ).

  Then, when any headword is touched and specified by the user touch T (step S17), a transition to the [jump destination headword selection screen Ga3] is confirmed, and the [jump destination headword selection screen] Ga3] image data P4s is associated with the operation data and registered as history data (operation-corresponding image) 4 in the search history data memory 12d (step S18).

  Then, the process proceeds to the search history display control process in FIG. 8 (step SA), and the search screen registered as the history data up to this time (here, history data 1, 2, 3, 4) in the search history data memory 12d. Image data (here, the image data P1s, P2r, P3s, P4s of the search screens Ga1, Gb1, Ga2, Ga3) are arranged in the lower left of the touch panel display unit 17 as a search history icon HS in which the image data is reduced. Displayed (Steps A1, A2 (No) → Return).

  Then, the explanation information corresponding to the entry word designated and displayed on the [jump destination entry word selection screen Ga3] is read from the jump destination dictionary, and the touch panel display section is displayed as the [description information display screen Gb2] (not shown). 17 (step S19).

  When one transition to the [description information display screen Gb2] corresponding to this headword is confirmed, the image data P5r of the [description information display screen Gb2] is associated with the operation data and the history of the search history data memory 12d. It is registered as data (operation corresponding image) 5 (step S20).

  Then, the process proceeds to the search history display control process in FIG. 8 (step SA), and is registered as history data up to this time (here, history data 1, 2, 3, 4, 5) in the search history data memory 12d. Image data of the search screen (here, the image data P1s, P2r, P3s, P4s, P5r of the search screens Ga1, Gb1, Ga2, Ga3, and Gb2) are arranged, and the touch panel is used as the search history icon HS in which the image data is reduced. It is displayed on the lower left of the display unit 17 (step A1).

  Here, using the search history data (12d) corresponding to a series of information search control processing in the dictionary search mode, a transition is made from any one of the search screens to another search screen to perform a new search. If the search history icon HS displayed on the lower left of the touch panel display unit 17 is touched by the user (step A2 (Yes)), the search history data memory 12d stores the history data 1 to 5 up to this time. The image data P1s to P5r of the registered search screens Ga1 to Gb2 are read out, and the image data P1s to P5r are sequentially read in the same manner as in the text browsing mode shown in FIG. 9C (B), for example.
