  In the electronic blackboard 10E, the official data of various units of learning materials (partial data corresponding to the figure formula) 12c is read from the external recording medium 13 or downloaded from the education server 20 and stored in the learning material data area 12b ( Steps S1 to S3 / S4, S5) As shown in FIG. 5A, for example, when the teacher draws a trapezoidal figure IL on the touch panel display unit 17 with the pen 18 (step S22 (Yes)), the drawn trapezoidal figure IL is drawn. Is stored in the work area 12f and displayed on the display unit 17 (step S23).

  Following the drawing of the trapezoidal figure IL, the area calculation formula F [trapezoid area = (upper base + lower base) × height / 2] is drawn (step S14 (Yes)). The formulated formula F is recognized and stored in the work area 12f and displayed on the display unit 17 (step S15).

  At this time, it is determined that the inputted mathematical formula (formula F) is not the formula Fn for numerical substitution (step S16 (No)), and the subsequent processing steps S17 to S21 are not executed at this point.

  Here, the learning material data area for the trapezoidal figure IL drawn and displayed on the display unit 17 and stored in the work area 12f and its formula F [trapezoid area = (upper base + lower base) × height / 2] Matching / non-coincidence with the official data of various units stored in 12b (partial data corresponding to graphic formulas) 12c is determined, and the same as the official data (partial data corresponding to graphic formulas) 12c2 of the unit "elementary school / trapezoidal area" When it is determined, the figure official icon M for notifying that the official data 12c2 of the corresponding unit is prepared is displayed on the upper right of the touch panel display unit 17.

  Here, as shown in FIG. 5B, when the upper base portion of the trapezoidal figure IL is designated by the pen 18, and green Gr is selected and set from a color menu (not shown) as the display color of the upper base portion (step S10). (Yes)), it is determined whether or not the designated upper base portion matches the graphic portion corresponding to the formula F [trapezoid area = (upper base + lower base) × height / 2]. (Step S11).

  Here, when it is determined that the designated upper base portion of the trapezoid graphic IL matches the graphic portion corresponding to the formula F [trapezoid area = (upper base + lower base) × height / 2]. (Step S11 (Yes)), it is determined whether or not the formula F [trapezoid area = (upper base + lower base) × height / 2] corresponding to the trapezoid graphic IL is displayed (step S12). ).

  When it is determined that the formula F [the area of the trapezoid = (upper base + lower base) × height ÷ 2] corresponding to the trapezoid graphic IL is displayed (step S12 (Yes)), the user The upper base portion of the specified trapezoidal figure IL is displayed with the user-set green Gr, and the corresponding portion [upper base] of the formula F is also identified and displayed with the same color green Gr (step S13).

  Accordingly, when the upper part of the figure IL displayed in the green Gr is designated and the numerical value “3” is input by handwriting (character recognition processing) with the pen 18 (step S24 (Yes)), the setting is made. The numerical value “3” is displayed on the upper bottom portion of the graphic IL (step S25).

  Then, it is determined whether or not the designated upper base portion matches the graphic portion corresponding to the formula F [trapezoid area = (upper base + lower base) × height / 2] (step) S26).

  Here, when it is determined that the designated upper base portion of the trapezoid graphic IL matches the graphic portion corresponding to the formula F [trapezoid area = (upper base + lower base) × height / 2]. (Step S26 (Yes)), the numerical value “3” set in the upper base portion is calculated as the calculation element [upper base] of the formula F [trapezoid area = (upper base + lower base) × height / 2]. Stored in association with each other (step S27).

  Thereafter, similarly, as shown in FIG. 5C, when the lower bottom portion of the displayed graphic IL is designated and the display color of red Re is set (step S10 (Yes)), the lower bottom portion of the graphic IL is set. Is displayed in red Re set, and the corresponding portion [lower base] of the formula F is also identified and displayed by red Re of the same color (steps S11 to S13).

  Accordingly, when the lower part of the figure IL displayed in red Gr is designated and the numerical value “7” is set by handwriting input (character recognition processing) with the pen 18 (step S24 (Yes)), the setting is made. The numerical value “7” is displayed on the lower base portion of the graphic IL (step S25), and the calculation element of the formula F [trapezoid area = (upper base + lower base) × height / 2] [lower base] Are stored in association with each other (steps S26 and S27).

  Similarly, as shown in FIG. 5C, when the height portion of the displayed graphic IL is designated and the display color of blue Bu is set (step S10 (Yes)), the height portion of the graphic IL is changed. In addition to the set blue Bu, the corresponding portion [height] of the formula F is also identified and displayed by the blue Bu of the same color (steps S11 to S13).

  Accordingly, the height portion of the graphic IL displayed in blue Bu is designated and the numerical value “4” is set by handwriting input (character recognition processing) with the pen 18 (step S24 (Yes)). The numerical value “4” is displayed in the height portion of the figure IL (step S25), and the calculation element [height] of the formula F [trapezoid area = (upper base + lower base) × height / 2] Are stored in association with each other (steps S26 and S27).

  Accordingly, each calculation element constituting each part of the trapezoidal figure IL displayed on the electronic blackboard 10E and the formula F of the trapezoid area [trapezoid area = (upper base + lower base) × height / 2] Can be identified and displayed in the color set by the user, and can be easily and clearly confirmed, and it is confirmed without error where the numerical value set by the user for each part of the graphic IL should be substituted as the calculation element of the formula F it can.

  Then, as shown in FIG. 5C, the correspondence between the trapezoidal figure IL and its formula F [trapezoid area = (upper base + lower base) × height ÷ 2] is identified by the display color set by the user. In the displayed state, as shown in FIG. 5D, for example, when a student refers to a numerical value set in each part of the graphic IL and substitutes the numerical value for the formula Fn, it is displayed by handwriting (character recognition processing). (Steps S14 (Yes), S15), it is determined and confirmed that the input mathematical formula is an official formula Fn substituted with a numerical value (Step S16 (Yes)), and the graphic IL corresponding to the formula Fn is displayed. (Step S17 (Yes)).

  Then, the numerical value input to each element part of the formula Fn assigned with the numerical value is changed to the display color (green Gr / red Re / blue Bu) set to each corresponding part of the graphic IL and each element part of the formula F, respectively. / Black K) for identification (step S18).

  Here, when it is determined and confirmed that a numerical value is set for each part of the graphic IL corresponding to the formula Fn assigned with the numerical value (step S19 (Yes)), the numerical value is set for each part of the graphic IL. It is determined whether or not the numerical value matches the numerical value assigned to each element part of the formula Fn associated therewith (step S20).

  If it is determined that the numerical values assigned to the element portions of the formula Fn do not match the numerical values set for the corresponding portions of the graphic IL (step S20 (No)), it is determined that they do not match. The numerical value in the formula Fn is displayed in an inverted manner or an error message is displayed (step S21).

  Specifically, as shown in FIG. 5D, the numerical value “2” assigned to the element portion of [Height] of the numerical value assigned formula Fn is displayed in inverted blue Bur, and a constant of [÷ 2]. The numerical value “4” assigned to the element portion is displayed in black Kr that is inverted.

  This not only allows the numerical values set corresponding to the colored portions of the graphic IL to be assigned to the corresponding element portions of the formula F without error, but even if incorrect numerical values are input. Since an erroneously input numerical value is notified to the user by a reverse display or an error message display, it is possible to easily correct the error and substitute the correct numerical value.

  Therefore, according to the graphic formula corresponding partial identification display function of the touch panel type information terminal device 10 having the above-described configuration, the formula F [trapezoid area = (trapezoid area = () is calculated in the learning material data area 12b. [Upper base + lower base) × height ÷ 2] is stored in association with each part of the graphic and each calculation element part of the formula F, and the graphic IL and the formula F are stored in the touch panel display unit 17. Display. Then, when each part of the displayed graphic IL is specified, it is determined whether or not the specified graphic part is a graphic part stored in association with the calculation element part of the formula F. If it is determined that the figure part is associated with the calculation element part, the part of the designated figure IL and the element part corresponding to the formula F are identified and displayed in the same display color (display form).

  Thus, each calculation element constituting each part of the trapezoidal figure IL displayed on the touch panel display unit 17 and the formula F of the trapezoid area [trapezoid area = (upper base + lower base) × height / 2] Can be easily and clearly confirmed, and the numerical value set in each part of the graphic IL can be confirmed without error as a calculation element of the formula F.

  Moreover, according to the figure formula corresponding | compatible part identification display function of the touchscreen type information terminal device 10 of the said structure, in the learning teaching material data area 12b, a plurality of types of figures and a plurality of types of formulas for calculating values related to the respective figures are displayed. When each part of the figure and each calculation element part of the formula are stored in association with each other and an arbitrary figure and formula are drawn on the touch panel display unit 17 in response to a user operation, the figure and formula are recognized. It is determined whether or not the type of graphic and formula to be stored are stored in the learning material data area 12b. Then, if it is determined that an arbitrary figure drawn by the user and a type of figure corresponding to the formula and the formula are stored, each part of the figure specified thereafter and the corresponding element part of the formula are the same It is identified and displayed in the display color (display form).

  As a result, for example, the teacher can use the figure drawn by hand on the electronic blackboard 10E and the formula as an example as it is for the lesson, and the student can calculate each part of the figure and the formula of the figure. The correspondence with the elements can be confirmed easily and clearly, and it can be confirmed without error where the numerical values set for each part of the figure should be substituted as the calculation element.

  In addition, according to the graphic formula corresponding part identification display function of the touch panel type information terminal device 10 having the above configuration, when the display color of the graphic part is set as the displayed graphic part is specified, the graphic part and the graphic part are displayed.
