In the case of a mouse or the like that does not detect an indication point by contact, a button operation or the like may be used as a condition.

  The marking in the present invention is a visually recognizable mark, mark, or modification attached to a designated character, and a specific marking mode is an achromatic color displayed with a predetermined positional relationship with respect to the designated character. Illustrative examples include line diagrams such as side lines, side points, underlines, erase lines, circle boxes, and square boxes with various colors, changes in the character color and background color of designated characters, and the like.

  In the present invention, for each of the designated characters, it further comprises a marking mode designating unit that accepts designation of the marking mode, and the marking unit accepts each of the designated characters by a marking mode designating unit. It is preferable to perform marking on the designated character (Claim 3), whereby markings in different forms are applied to portions that remain in the impression, portions that feel interesting, portions that are considered important, etc. Can be used for organizing the content of the text and for deepening understanding of the text.

  In the present invention, a plurality of designated character recording means each for recording one or a plurality of the designated characters, markings for the designated characters recorded in one designated character recording means, and other designated character recording means Contrast mode selection means for accepting a designation of a contrast mode for displaying the marking for the designated character recorded in contrast, and when the contrast mode is designated, the marking means is one of the designations Preferably, the marking for the designated character recorded in the character recording means and the marking for the designated character recorded in the other designated character recording means are displayed simultaneously.

  In such an invention, using the information display device of the present invention, two (or three or more) users can mark parts that remain in impressions, parts that feel interesting, parts that are considered important, etc. In the past, when reading while performing, comparing each user's marked part (designated characters) and the type of marking, you can enjoy the reading feeling of other users, read while referring, etc. There can be no new reading form available.

  Or, if you read the same sentence twice over a period of time, compare the markings you read in the past with the markings you read this time, and enjoy the change in your understanding and reading feeling It is possible to provide an unprecedented new form of reading such as reading.

  In this case, when the designation of the contrast mode is accepted by the contrast mode selection means, the marking means includes marking for the designated character recorded in one designated character recording means and another designated character recording. It is preferable to display the markings for the designated characters recorded in the means in different manners (Claim 5), so that the markings made by other users can be compared with the markings read by other users or read in the past and this time. This makes it easier to understand the marking contrast.

  In the present invention, it is preferable that the specified character specifying means specifies the specified character in a predetermined syntax unit.

  In the present invention, a syntax unit is a group of characters (a set of one or more characters) that form a group in some sense that constitutes a sentence such as a word, a clause, a phrase, or a paragraph.

  In general, the task of specifying a specific part of a sentence is often done for the purpose of editing or marking the part, but under such a purpose, semantically, grammatically, etc. It may be convenient to specify in units of characters (words, phrases, phrases, paragraphs, etc.) that are grouped in some way.

  The specified character specifying means of the present invention specifies a specified character in units of such a group of characters (words, phrases, phrases, paragraphs, etc.). Can be facilitated.

  The specified character specifying means of the present invention specifies a plurality of types of syntax units in a single sentence, such as specifying a specified character in a word unit in a part of a sentence and specifying a specified character in a paragraph unit in another part. The specified character may be specified by.

  In the present invention, it is preferable that the sentence is recorded on the predetermined recording medium in a state in which delimiter information for delimiting the sentence is set in the syntax unit.

  That is, when the designated character identification means identifies a designated character in a syntax unit, for example, an appropriate syntax analysis tool such as “tea bowl” available at “http://chasen.naist.jp/hiki/ChaSen/” It is also possible to specify a designated character for each predetermined syntactic unit obtained by decomposing a sentence using, but in the information display device, syntax analysis by the above tools, specification of the designated character and marking If processing such as display is executed in parallel, the calculation load may be excessive. In addition, in the automatic analysis using the tools as described above, the sentence may not necessarily be decomposed into an appropriate syntactic unit suitable for the user's purpose of use. Therefore, if it is a sentence prepared in advance such as a novel, it is possible to reduce the calculation load in the information processing apparatus by using a sentence in which delimiter information for dividing the sentence in units of syntax is set in advance, or It is possible to reliably specify the designated character in an appropriate syntactic unit suitable for the purpose of use of the user.

  It should be noted that all the delimiter information in the present invention can be set by manual operation, or delimiter information can be set for each syntax unit by automatic analysis using some syntax analysis tool, or the above-mentioned After setting the delimiter information for each syntax unit by automatic analysis using a syntax analysis tool like this, it is also possible to improve the delimiter information by adding and deleting delimiter information in a manner that makes manual adjustments .

  In the present invention, it is preferable that the sentence is displayed in a plurality of lines on the display screen, and the designated character specifying unit specifies the designated character in a line where a start point of the locus is located (Claim 8). Thus, the designated character designation work can be facilitated.

  In the present invention, the sentence is at least a part of a quiz question, and an answer to the question is accepted by designation of the designated character (Claim 9), or further, the designated character is displayed on the display screen. Or a designated character display means to be displayed on another display screen provided separately (claim 10), thereby facilitating the input of a quiz answer, and a fresh and interesting aspect It is possible to input an answer to the quiz.

When is selected, the process of copying the marking data MD in the corresponding user files UFa to UFc of the memory card 16 to the comparison designated character recording means 43 is executed.

  The auxiliary function processing unit 32b transmits a predetermined comparison signal to the marking comparison unit 39 in order to execute the marking comparison display in the text display unit 61 after performing the above-described data copying.

  The display setting means 32c operates when the setting tab 62c of the menu section 62 is operated with the stylus 17, and receives designation of the character font type and size of the text displayed on the text display section 61.

  The indication point detection means 33 derives the position coordinates of the indication point on the display screen 13a touched by the stylus 17 based on the signal output from the touch panel 13b, and this is derived as a trajectory display means 34, an input completion detection means 35, This is notified to the designated character specifying means 36 and the marking erasing means 38.

  The trajectory display means 34 executes a process of drawing an image of the trajectory of the indication point based on the position coordinates of the indication point notified from the indication point detection means 33 every moment, and receives a predetermined input completion signal from the input completion detection means 35. Every time the “” is received, the process of deleting the locus drawn so far is executed.

  The input completion detection unit 35 transmits the input completion signal to the trajectory display unit 34 and the designated character identification unit 36 when a predetermined condition is satisfied.

  The predetermined condition in the present invention can be any condition that can reasonably infer completion of the designated input by the user for designating one designated character, but the input completion detecting means 35 of the present embodiment After the notification of the first position coordinate from the indication point detection means 33, it is determined that the predetermined condition is satisfied when the notification of the position coordinate is lost.

  The designated character specifying unit 36 operates upon reception of an input completion signal from the input completion detection unit 35, and the locus drawn by the locus display unit 34 (notified from the indication point detection unit 33 until the input completion signal is received). The designated character is specified based on all the position coordinates), and the marking data MD for the specified designated character is recorded in the designated character recording means 42.

  The specified character specifying method based on the trajectory in the present invention can be arbitrary as long as the user does not feel a great sense of discomfort with the correspondence between the specified trajectory and the specified character. The means 36 divides the display screen 13a into rectangular syntax unit areas K1 to Kn in which each syntax unit is displayed, and is a syntax unit area K1 to Kn in the lines L1 to L9 where the start point of the trajectory T is located. When the dimension of the trajectory T (direction perpendicular to the line direction) of the trajectory T in the syntax unit areas K1 to Kn is equal to or greater than a predetermined ratio of the dimension of the syntax unit areas K1 to Kn in the text feed direction. The syntax units in the areas K1 to Kn are specified as designated characters. The syntax unit areas K1 to Kn are areas combined with the character display area R for the characters constituting each syntax unit. In order to appropriately specify the character intended by the user as the designated character, the predetermined ratio is preferably about 30 to 80%, and is 40% in the present embodiment.

  FIG. 9A is an explanatory diagram showing a specific mode of the designated character by the designated character specifying means 36. In this figure, the sentence display unit 61 uses the delimiter information D1, D2,... In the sentence data Da. The syntax unit areas K1 to K5 for some of the defined syntax units (five syntax units of “Meros”, “Ha”, “Kano”, “evil violence” and “unless to exclude”) are framed. It is indicated by a line.

  In the drawing, Ta to Tc are trajectories drawn by the trajectory display means 34, and the black circles at the upper and lower ends thereof are the start and end points of the trajectories Ta to Tc, respectively.

  Regarding the trajectory Ta, there are two syntax unit areas K1 and K2 through which the trajectory Ta passes in the line L1 where the start point is located. The dimension of the trajectory Ta in the syntactic unit area K1 in the character feeding direction (the direction of the arrow X in the drawing) is 40% or more of the dimension in the character feeding direction of the syntactic unit area K1, but the trajectory Ta in the syntactic unit area K2. The dimension in the character feeding direction is less than 40% of the dimension in the character feeding direction in the syntax unit area K2. For this reason, when the trajectory Ta is drawn by the trajectory display means 34, the designated character specifying means 36 specifies only “Meros”, which is a syntax unit in the syntax unit area K1, as the specified character.

  Regarding the locus Tb, the locus Tb meanders and passes through the syntax unit region K2 in the row L1 adjacent to the row L2 where the start point is located. However, the designated character specifying means 36 is within the line where the start point of the locus is located. Since only the designated character is identified, “ha”, which is the syntax unit in the syntax unit area K2, is not identified as the designated character. In the row L2 in which the start point of the locus Tb is located, the dimension in the feeding direction of the locus Tb in the two syntax unit areas K3 and K4 is 40% or more of the dimension in the feeding direction of each syntax unit area K3 and K4. Therefore, the designated character specifying means 36 specifies “Kano” and “evil violence”, which are the syntax units in the syntax unit areas K3 and K4, as the designated characters.

  Regarding the trajectory Tc, the syntactic unit region through which the trajectory Tc passes is only K5 in the row L2 where the start point is located. Here, the syntax unit “not to be removed” in the syntax unit area K5 is displayed over two lines of the line L2 and the line L3, but the character feed direction of the locus Tc in the syntax unit area K5. Since the dimension is 40% or more of the dimension in the character feeding direction of the syntax unit area K5, the designated character specifying unit 36 specifies “not to be removed” which is a syntax unit in the syntax unit area K5 as the designated character. .

  FIG. 9B is an explanatory diagram conceptually showing the data contents of the marking data MD recorded on the designated character recording means 42 by the designated character specifying means 36.

  As shown in the drawing, the marking data MD is composed of five data elements of “data number”, “start identification number”, “end identification number”, “color information”, and “shape information”.

  Here, the “data number” is a serial number assigned to each marking data MD.

  The “start identification number” and “end identification number” are identification numbers of the first syntax unit and the last syntax unit of the syntax units constituting the specified character. For example, the “data number” is “3” marking In the data MD, it is shown that the six characters “Kano violent Nachi” from the syntax unit with the identification number “9” to the syntax unit with the identification number “10” are designated characters, and the “data number” In the marking data MD with “6”, the designated characters are 10 characters “sensitive to one person” from the syntax unit with the identification number “57” to the syntax unit with the identification number “62”. It is shown. Therefore, in the marking data MD having the same “start identification number” and “end identification number” (for example, marking data MD having “1”, “2”, and “4” as the “data number”), a single syntax is used. The unit is specified as the designated character.

  “Color information” and “shape information” indicate the display color and shape of the marking M received by the marking mode designation means 32a.

  The designated character specifying unit 36 executes a process of recording the marking data MD in the form of FIG. 9B in the designated character recording unit 42 every time the designated character is specified in the form described above with reference to FIG.

  The designated character specifying means 36 determines whether the designated character in the marking data MD newly recorded in the designated character recording means 42 is the same as the designated character in the marking data MD already recorded in the designated character recording means 42, or When the “color information” and “shape information” of both marking data MD are the same, including the previous and subsequent syntax units, the process of rewriting the two marking data MD into a single marking data MD is performed. Execute. For example, in the state where the marking data MD whose “data number” is “1” in FIG. 9B is already recorded in the designated character recording means 42, “color information” is set to “red”, and “shape information” is set to “ When the syntax unit “ha” having the identification number “2” as a straight line is newly specified as the designated character, the “end identification number” in the marking data MD whose “data number” is “1” is set to “2”. Is rewritten.

  On the other hand, the designated character specifying means 36 is such that the designated character in the marking data MD newly recorded in the designated character recording means 42 is the same as the designated character in the marking data MD already recorded in the designated character recording means 42. If the “color information” or “shape information” is different, the new marking data MD is recorded as designated character data as data independent of the marking data MD already recorded in the designated character recording means 42. Recorded in means 42. For example, in the state where the marking data MD whose “data numbers” are “1” and “2” in FIG. 9B has already been recorded in the designated character recording means 42, the syntax unit of “Meros” with the identification number 1 is Even when a new designated character is specified, if “color information” is “blue” or “shape information” is “circle”, the marking data MD has a “data number” of “1”. And the designated character recording means 42 as data independent of the marking data MD “2”.

  Further, the example marking data GMD and the marking data MD recorded in the contrast designation character recording unit 43 by the auxiliary function processing unit 32b have the same data format as the marking data MD described above with reference to FIG. 9B. . The explanation data GC is text data composed of sentences explaining the reason for marking each example marking data GMD. Each explanation data GC is correlated with the data number of each example marking data GMD. It is recorded in the designated character recording means 43.

  The marking unit 37 executes a process of displaying the marking M on the sentence display unit 61 in accordance with the marking data MD recorded in the designated character recording unit 42.

  FIG. 10A is an explanatory diagram showing a marking display mode in the text display section 61 when the marking data MD of FIG. 9B is recorded in the designated character recording means 42, and marking M1 in the figure To M6 respectively correspond to the marking data MD whose “data numbers” in FIG. 9B are “1” to “6”. The symbols (r), (b), and (g) shown at the bottom of the symbols M1 to M6 in FIG. 10A indicate that the display colors of the markings M1 to M6 are “red”, “blue”, and “ “Green”. The markings M1 to M6 displayed by the marking means 37 are markings M (for example, markings) whose position (for example, the number of points from the right end of the character display area R), line width, and shape in the character display area R is “circle”. The upper and lower curvatures in the case of M5) are standardized.

  As described above, in the information display device 10 of the present embodiment, the movement locus (for example, Ta) of the indicated point by the stylus 17 on the display screen 13a is drawn by the locus display means 34, and the stylus 17 is separated from the display screen 13a. At the time, the input completion detection means 35 detects the completion of the designated input, and the locus (for example, Ta) drawn by the locus display means 34 is deleted, and the marking (for example, M1) by the marking means 37 is newly displayed. . Therefore, the locus that is a freehand line is transformed into a shaped or standardized marking so that the user can enjoy marking, or feel refreshed or pleasant to perform marking. I can feel it.

  The marking erasure unit 38 is activated by receiving an erasure signal from the marking mode designation unit 32a, and erases the marking data MD for the marking M designated by the stylus 17 from the designated character recording unit 42 after receiving the signal. Execute the process. As a result, the display of the marking M in the text display unit 61 is deleted. In addition, it is arbitrary what kind of operation is performed, and it is arbitrary whether marking of marking M to be erased is designated. However, the marking erasing unit 38 in the present embodiment is not limited to the display screen 13a. When the stylus 17 touches even one point of the marking M display area, the marking M is erased. For example, after the marking erasing unit 38 receives the erasing signal, the stylus 17 performs the processing with the stylus 17. When the trajectory Td shown in FIG. 10 (A) is drawn, the marking erasure unit 38 executes a process of erasing the marking data MD for the markings M1 to M3 and M5 from the designated character recording unit 42 until the marking. These markings M1 to M3 and M5 displayed by the means 37 are erased on the display screen 13a.

  The marking comparison means 39 is activated when a comparison signal is received from the auxiliary function processing means 32b, and executes the display of the text screen 60 in the comparison mode. That is, the marking comparison unit 39 executes a process of displaying the comparison marking CM on the sentence screen 60 based on the example marking data GMD or the marking data MD recorded in the comparison designation character recording unit 43 by the auxiliary function processing unit 32b. To do.

  FIG. 10B is an explanatory diagram illustrating an exemplary aspect of the sentence screen 60 in a state where the comparison markings CM1 to CM4 are displayed by the marking comparison unit 39.

  As shown in the drawing, on the text screen 60 in the contrast mode, markings M1 to M6 based on the marking data MD recorded in the designated character recording means 42 are marked by the marking means 37 in the same manner as described above with reference to FIG. The marking marking data GMD recorded in the contrast designation character recording means 43 or the contrast markings CM1 to CM4 based on the marking data MD are displayed by the marking contrast means 39.

  Here, the display form of the contrast marking CM is arbitrary, but the marking contrast means 39 of the present embodiment can be used in an atmosphere like marking with a highlighter on a sentence printed on paper. The marking of the aspect which changes the background color of the designated character in the model marking data GMD or the marking data MD is displayed. (R), (b), and (g) shown at the bottom of the symbols CM1 to CM4 in FIG. 10 (B) indicate that the background colors in the contrast markings M1 to M6 are “red”, “blue”, and It shows that it is “green”.

  In this way, the embodiment marking data GMD recorded in the contrast designated character recording means 43 or the contrast marking CM for the marking data MD is different from the marking M for the marking data MD recorded in the designated character recording means 42. The user can read the marking M made by the user while comparing the marking M performed by the user with the contrast marking CM performed by another user (or the marking CM used as a model). It is possible to read while comparing the contrast marking CM performed when reading the text with the marking M performed this time.

  When the data recorded in the contrast designation character recording means 43 is the marking data MD, each marking data MD also has “shape information”, but the marking contrast means 39 of the present embodiment In order to prevent the display of the text screen 60 from becoming complicated, the above-described uniform marking contrast CM is displayed regardless of the “shape information” of each marking data MD.

  Further, the “i” mark displayed on the left shoulder position of each of the contrast markings CM1 to CM4 indicates that each of the contrast markings CM1 to CM4 when the data recorded in the contrast designation character recording means 43 is the sample marking data GMD. When the icon “i” is touched by the stylus 17, the marking contrast means 39 is associated with the “data number” of the corresponding example marking data GMD. The comment data GC is displayed as text on the display screen 12a, for example.

  The quiz means 40 executes processing for displaying quiz questions on the display screen 13a when a quiz signal is received from the action selection means 30, and includes a quiz recording means 40a, quiz question means 40b, indication point detection. Means 40c, trajectory display means 40d, answer input completion detection means 40e, answer specifying means 40f, answer display means 40g, and correctness determination means 40h are provided.

  Here, the quiz recording means 40a records a plurality of types of quiz questions and answers corresponding to the respective quiz questions in a text format, and the quiz questioning means 40b is a quiz recorded in the quiz recording means 40a. A process of displaying the quiz screen 70 on which the problem is displayed on the display screen 13a is executed.

  FIG. 11A is an explanatory diagram showing an exemplary quiz screen 70.

  As shown in the figure, on the quiz screen 70, an answer display field 70a in which at least a part of any of the quiz questions recorded in the quiz recording means 40a is displayed as text, and an answer that displays an answer input by the user. And a display column 70b.

  The indication point detection means 40c, the trajectory display means 40d, the answer input completion detection means 40e, and the answer specification means 40f operate in a state where the quiz screen 70 is displayed on the display screen 13a, respectively, and the indication point detection means 33, By executing the same processing as the trajectory display means 34, the input completion detection means 35, and the designated character specifying means 36, an answer by the user is received. That is, the quiz problem of the quiz recording means 40a is recorded in a state in which the delimiter information is set for each predetermined syntax unit as in the case of the text data Da to Dn, and the indication point detection means 40c is displayed on the display screen 13a. The indication point by the stylus 17 is detected, the locus display means 40d displays the movement locus Te of the indication point on the quiz screen 70a, and the answer input completion detection means 40e is provided on condition that the stylus 17 is separated from the display screen 13a. The completion of answer input is detected, and the answer specifying unit 40f executes processing for specifying one or more characters designated by the user in the same manner as the designated character specifying unit 36 in the above-mentioned syntax unit.

  Then, the answer display means 40g displays the character specified by the answer specifying means 40f in the answer display column 70b, and the correctness determination means 40h records the character specified by the answer specifying means 40f in the quiz recording means 40a. By comparing with the answer, the correctness of the user's answer is determined, and a process of displaying on the quiz screen 70 a display such as “correct answer” and “wrong” according to the correctness is executed.

  FIG. 12 is a flowchart showing the flow of the marking display process in the state where the display color and shape of the marking M are specified by the marking mode specifying means 32a.

  When the process is started, initialization processing such as setting the input flag F to OFF and setting the counter N to zero is executed in step S1, and in step S2, the input flag F is checked. The

  If the in-input flag F is off as a result of the inspection in step S2, the process proceeds to step S3, and the indication point detection means 33 displays the display screen 13a by the stylus 17 based on the signal from the touch panel 13b. Perform a check for contact.

  If the contact of the stylus 17 is detected in step S3, a process of setting the input flag F to ON is executed in step S4. If the contact of the stylus 17 is not detected, step S4 is performed. Without executing, the process proceeds to step S17.

  If the in-input flag F is ON in step S2, the process proceeds to step S5, and the indication point detection unit 33 displays the display screen 13a by the stylus 17 based on the signal from the touch panel 13b. Perform a check for contact.

  If the contact of the stylus 17 is detected in step S5, the process proceeds to step S6, and based on the signal from the touch panel 13b, the indication point detection means 33 derives the XY coordinate value of the indication point. In step S7, the indicated point (the coordinate value) is notified to the trajectory display means 34 and the designated character specifying means 36. In the subsequent step S8, the locus display means 34 operates, and the locus T is drawn by executing a process of drawing a dot of a predetermined color with a predetermined point size at the indicated point notified in step S7.

  On the other hand, if the contact of the stylus 17 is not detected in step S5, the process proceeds to step S9, and a process of incrementing the counter N by “1” is executed. In step S10, the input completion detection unit 35 operates. Thus, a process for comparing the counter N with a predetermined threshold Nth (for example, “5”) is executed.

  If the counter N is equal to or greater than the threshold value Nth, it can be determined that the user's designated input has been completed. Therefore, after the input flag F and the counter N are initialized in step S11, the input is performed in step S12. A completion signal is transmitted to the trajectory display means 34 and the designated character specifying means 36.

  In step S13, the trajectory display means 34 operates, and an erase process for the trajectory T is executed to erase all the dots drawn in step S8 in each frame time after the in-input flag F is set on in step S4. Is done.

  In the subsequent step S14, the designated character identifying means 36 operates to execute the designated character identifying process in the manner described above with reference to FIG. 9A. In step S15, the marking data MD for the identified designated character is designated as the designated character. Recorded in the recording means 42.

  In step S <b> 16, the marking unit 37 operates to execute a process for displaying the marking M for each marking data MD recorded in the designated character recording unit 42 on the sentence display unit 61.

  In step S17, after a standby process for a predetermined frame time (for example, 1/60 seconds) is executed, the process returns to step S2 to execute the marking display process for the next frame time.
