  In the correct image display area 102, an image showing the correct answer of the question being scored is displayed. In the input image display area 103, an answer image to be scored is displayed. In the previous image display area 104, an answer image that has been scored immediately before the answer image displayed in the input image display area 103 is displayed. If the sub-question is a problem related to drawing, as shown in FIG. 4, an image of the model answer drawing is displayed in the correct image display area 102, and the input image display area 103 and the previous image display area 104 are displayed. The image of the answer drawing drawn by the examinee is displayed.

  In the identification number list 106, the identification numbers that are the target of scoring in the question being scored are displayed in a list format. In the example of FIG. 4, the identification number currently being scored, that is, the identification number in which the answer image is displayed in the input image display area 103 is focused. Also, on the right side of the identification number, the input value of the grader, that is, the scoring result is displayed.

  The input buttons 108 to 113 are used for inputting a scoring result of each answer image. For example, the correct answer button 108 is pressed when the answer image displayed in the input image display area 103 is correct, and the incorrect answer button 109 is pressed when the answer image is incorrect. Further, when there is no answer, the no answer button 110 is pressed, and when the scoring is put on hold, the hold button 111 is pressed. In addition, the questions to be scored can be changed with the “Previous” button 112 or the “Next” button 113.

  Next, each part which comprises the verification part 26 in the scoring processing apparatus 14 shown in FIG. 1 is demonstrated. The display position receiving unit 40 receives from the input device 18 a display position for displaying a verification graphic for verifying the answer drawing drawn by the examinee on the display device 16. Here, the verification graphic includes, for example, an image of an exemplary answer drawing corresponding to the answer drawing in addition to a graphic such as a straight line, a circle, or a triangle.

  The display unit 42 generates image data for displaying the verification graphic at the display position received by the display position receiving unit 40. The display unit 42 displays image data for displaying the verification figure superimposed on the answer drawing image in a state where the image of the answer drawing displayed in the input image display area 103 of the scoring screen 100 is visible. Can be generated. Further, the display unit 42 can generate image data for displaying the contour line of the verification graphic in a color different from the contour line of the image of the answer drawing. In this way, by changing the colors of the verification graphic and the answer drawing image, the verification graphic and the answer drawing image can be easily distinguished when the verification graphic is superimposed on the answer drawing image. It becomes possible.

  The adjustment instruction receiving unit 44 receives an instruction to adjust the display position and size of the verification graphic displayed on the display device 16 from the input device 18.

  The adjustment unit 46 adjusts the display position and size of the verification graphic displayed on the display device 16 based on the adjustment instruction received by the adjustment instruction reception unit 44.

  Details of each unit constituting the verification unit 26 will be described using a specific example. FIG. 5 is a diagram illustrating an example of a verification screen displayed on the display device 16 in accordance with the image data from the verification unit 26.

  The verification screen 130 includes a display area 132, selection buttons 134 to 141, check boxes 150 and 152, an angle display area 154, a transparency adjustment gauge 156, and a function explanation area 158. Here, the verification screen 130 is a translucent screen in which a screen existing behind can be visually recognized. For example, as shown in FIG. 6, the verification screen 130 can be displayed on the scoring screen 100 in a state where the image displayed on the scoring screen 100 is visible.

  Note that the check box 150 is turned off, so that the display unit 42 can temporarily prevent the image displayed in the display area 132 from being displayed until the check box 150 is turned on again. When the check box 152 is turned on, the display unit 42 can generate image data that causes the verification screen 130 to be always displayed in the foreground compared to other screens. The display unit 42 can adjust the transparency of the verification screen 130 according to the setting of the transparency adjustment gauge 156.

  The display area 132 is an area where a verification graphic is displayed. The display position receiving unit 40 receives a display position on the display area 132, and the display unit 42 generates image data for displaying a verification graphic on the display area 132. The adjustment instruction receiving unit 44 receives an adjustment instruction on the display area 132, and the adjustment unit 46 adjusts the position and size of the verification graphic on the display area 132.

  On the verification screen 130, it is possible to draw straight lines, circles, and triangles, and it is possible to display images such as model answer drawings. Switching of functions on the verification screen 130 can be performed by using the selection buttons 134 to 141. As shown in FIG. 5, the function explanation area 158 displays an operation explanation for the selected function.

  Each function corresponding to the selection buttons 134 to 141 will be described in order. In the following description, it is assumed that the input device 18 is a mouse. However, the input device 18 is not limited to a mouse and may be any device that can operate the verification screen 130.

  FIG. 7 is a diagram illustrating an example of plotting when the straight line button 134 is selected. For example, if the point X1 on the display area 132 is selected with the mouse while the straight line button 134 is selected, and the mouse cursor 160 is moved to the point X2 as it is, a straight line from the point X1 to the point X2 is drawn. The In this case, the display position accepting unit 40 accepts “straight line” as the graphic type information, accepts the start point X1 and the end point X2 as the display position, and the display unit 42 includes the start point X1 and the end point X2 on the display area 132. The image data for displaying is generated. At this time, the display unit 42 generates image data that causes the angle display area 154 to display an angle θ with respect to a reference line of a straight line including the start point X1 and the end point X2.

  In addition, the position of the start point or end point of the straight line can be changed by moving the mouse cursor 160 with the start point X1 or end point X2 selected with the mouse. In addition, it is possible to move the straight line by moving the mouse cursor 160 with an arbitrary point on the straight line between the start point X1 and the end point X2 selected with the mouse.

  In this case, the adjustment instruction receiving unit 44 receives a display position or size adjustment instruction, and the adjustment unit 46 changes the straight line display position or size in the display area 132. The adjustment instruction receiving unit 44 temporarily changes the color of the line when the mouse cursor 160 is moved to the start point X1 or the end point X2, or any point on the line. In this way, by changing the color of the straight line, the user can be made aware that an operation on the straight line is possible.

  FIG. 8 is a diagram showing an example of plotting when the center instruction ○ button 135 is selected. For example, when a point on the display area 132 is selected as shown in FIG. 8A with the center instruction ○ button 135 selected, a circle with a predetermined radius centered on the point is drawn. The center point of the circle is also displayed. In this case, the display position accepting unit 40 accepts “center indication circle” as the graphic type information, accepts the center of the circle as the display position, and the display unit 42 displays a circle centered on the accepted position in the display area 132. Image data to be displayed is generated.

  Further, as shown in FIG. 8B, the size of the circle can be changed by selecting the circumference (outline) of the circle with the mouse and moving the cursor 160 of the mouse. In addition, the circle can be moved by moving the cursor 160 of the mouse while the center point (position adjustment point) of the circle is selected with the mouse.

  In this case, the adjustment instruction receiving unit 44 receives a display position or size adjustment instruction, and the adjustment unit 46 changes the display position or size of the circle in the display area 132. The adjustment instruction accepting unit 44 temporarily changes the color of the circumference when the mouse cursor 160 is moved to the center point or circumference of the circle. Thus, by changing the color of the circumference, the user can be made aware that an operation on the circle is possible.

  FIG. 9 is a diagram showing an example of the drawing when the three-point instruction ○ button 136 is selected. For example, when the three-point instruction ○ button 136 is selected, if three points on the display area 132 are selected with the mouse as shown in FIG. 9A, the selected points are displayed as shown in FIG. 9B. A circle is drawn through which the circumference (outline) passes through three points.

  In this case, the display position receiving unit 40 receives “three-point instruction circle” as the graphic type information, receives the three selected points as the display position, and the display unit 42 displays a circle passing through the three received points as a display area. Image data to be displayed on 132 is generated. Note that the display position and size of the circle drawn by the three-point instruction can be changed in the same manner as the circle drawn by the center instruction.

  FIG. 10 is a diagram showing an example of the drawing when the three-point instruction Δ button 137 is selected. For example, when the three-point instruction Δ button 137 is selected, if three points on the display area 132 are selected with the mouse as shown in FIG. 10A, the selected points are displayed as shown in FIG. 10B. A triangle in which three points are the vertices of three sides (outline) is drawn. The center point of the triangle is also displayed.

  In this case, the display position accepting unit 40 accepts “three-point indication triangle” as the graphic type information, accepts the selected three points as the display position, and the display unit 42 selects the triangle having the accepted three points as vertices. Image data to be displayed in the display area 132 is generated.

  In addition, by moving the mouse cursor 160 with any of the three vertices selected with the mouse, the position of the selected vertex can be changed without changing the position of the other vertex. At this time, the angle display area 154 displays the angle of the selected vertex. In addition, the triangle can be moved by moving the mouse cursor 160 in a state where the center point (position adjustment point) of the triangle is selected with the mouse.

  In this case, the adjustment instruction receiving unit 44 receives a display position adjustment instruction, and the adjustment unit 46 changes the display position of the triangle in the display area 132. The adjustment unit 46 also generates image data for displaying the angle of the selected vertex in the angle display area 154. When the mouse cursor 160 is moved to the apex or center point of the triangle, the adjustment instruction receiving unit 44 temporarily changes the color of the sides of the triangle. Thus, by changing the color of the sides of the triangle, the user can be made aware that the operation on the triangle is possible.

  FIG. 11 is a diagram showing an example of plotting when the enlargement / reduction / rotation button 138 is selected. For example, when the enlargement / reduction / rotation button 138 is selected, the center point (size adjustment point) of the triangle is selected with the mouse as shown in FIG. 11A, and the mouse cursor 160 is moved in a certain direction (for example, the center point). When it is moved downward), the triangle is enlarged according to the moving distance of the cursor 160. Conversely, when the mouse cursor 160 is moved in a different direction (for example, upward) from the center point, the triangle is reduced according to the movement distance of the cursor 160. Further, for example, when the enlargement / reduction / rotation button 138 is selected, one of the vertices of the triangle is selected with the mouse and the mouse cursor 160 is moved as shown in FIG. The triangle can be rotated around the point.

  In this case, the adjustment instruction receiving unit 44 receives an instruction to adjust the size or display position, and the adjustment unit 46 changes the size or display position of the triangle in the display area 132. The adjustment instruction receiving unit 44 temporarily changes the color of the side of the triangle when the mouse cursor 160 is moved to the center point or vertex of the triangle. In this way, by changing the color of the side, the user can be made aware that an operation on the triangle is possible. Further, not only a triangle but also a circle and a straight line can be similarly enlarged, reduced, and rotated. In the case of a straight line, the size (length) of the straight line can be changed by selecting an arbitrary point on the straight line and moving the cursor 160 of the mouse. The straight line can be rotated by selecting the start point or end point of the straight line and moving the cursor 160 of the mouse.

  In addition, when the graphic copy button 139 is selected, the graphic displayed on the display area 132 is selected, and the mouse cursor 160 is moved, thereby copying the original graphic to the point after the movement. Is displayed.

  In this case, the display position receiving unit 40 receives information on the original graphic and also receives the newly selected point as the display position, and the display unit 42 copies and displays the original graphic on the newly selected point. The image data to be generated is generated.

  FIG. 12 is a diagram illustrating an example of an operation when the image rotation button 140 is selected. FIG. 12A is an example of an image displayed on the display area 132. An image can be displayed on the display area 132 by, for example, dragging and dropping an image file onto the display area 132.

  In this case, the display position receiving unit 40 receives a position where the image file is dragged and dropped on the display area 132, and the display unit 42 generates image data for displaying an image at the position.

  When the image is displayed in the display area 132 as described above, the image can be rotated by selecting the image rotation button 140. For example, in the state where the image rotation button 140 is selected, as shown in FIG. 12B, when the point X1 that is the center of rotation is selected, and when the start point X2 and the end point X3 of the rotation are further selected with the mouse, The entire image rotates about the angle X1 by the angle between the straight line X1-X2 and the straight line X1-X3.

  In this case, the adjustment instruction receiving unit 44 receives the points X1 to X3 as adjustment instructions, and the adjustment unit 46 changes the display position of the image based on the selected points X1 to X3.

  Further, with the image moving button 141 selected, the image displayed on the display area 132 can be selected by, for example, left clicking with the mouse, and the mouse cursor 160 is moved, thereby moving the image. . In addition, when the image move button 141 is selected, an image displayed on the display area 132 is selected by, for example, right-clicking with the mouse, and the cursor 160 of the mouse 160 is moved. The image can be enlarged or reduced according to the distance.

  In this case, the adjustment instruction receiving unit 44 receives a display position or size adjustment instruction, and the adjustment unit 46 changes the display position or size of the image in the display area 132.

  Next, an example of a procedure for the examinee to verify the answer drawing using the scoring device 14 will be described. FIG. 13 is a diagram showing an example of a drawing in a certain question.

  FIG. 13A is a drawing described on the problem paper. For example, it is assumed that the sub-question is “a point C on the arc A-B where the angle of the BOC is 45 degrees should be obtained by drawing”.

  FIG. 13B is an exemplary answer drawing for this sub-question. This model solution drawing is drawn as follows. First, as shown in FIG. 14A, an arc having the same radius is drawn around the points A and B, and a perpendicular line from the center point O is drawn by connecting the intersection and the center point O of the semicircle. . Thereafter, as shown in FIG. 14B, an arc having the same radius is drawn around the intersection D and the point B between the perpendicular and the arc, and the intersection and the center point O are connected to make the BOD second A line to be divided is drawn, and C is obtained by the intersection of this line and the semicircular arc.

  FIG. 13C is an answer drawing drawn by a test taker. Here, comparing the model answer drawing of FIG. 13 (b) with the answer drawing of FIG. 13 (c), the position of the point C seems to be correct, but at first glance it is shown how it was drawn. Cannot be judged. Therefore, the grader displays the answer drawing image of FIG. 13C in the input image display area 103 of the scoring screen 100, and the display area 132 of the verification screen 130 overlaps the image of the answer drawing. Thus, the verification drawing is verified by displaying the verification graphic on the display area 132.

  FIG. 15 is a diagram showing an example of a verification graphic drawn on the verification screen 130 by the grader. In FIG. 15, the contour of the image of the answer drawing is indicated by a solid line, and the contour of the verification graphic is indicated by a broken line.

  First, as shown in FIG. 15A, the grader depresses the center instruction ○ button 135, draws a circle 170 centered on the point A, and a part of the circumference is a locus 172 in the answer drawing. Adjust the size of the circle so that it overlaps with. Here, as shown in FIG. 15A, when a part of the circumference overlaps with the locus 172, it can be determined that the locus 172 is drawn around the point A.

  Subsequently, the grader depresses the graphic copy button 139 and copies the circle 170 to draw a circle 174 having the same radius as the circle 170. Then, the scorer moves the circle 174 so that the center point of the circle 174 becomes the point B. Here, as shown in FIG. 15A, when a part of the circumference of the circle 174 overlaps with the trajectory 176 that intersects the trajectory 172, the trajectory 176 has the same radius as when the trajectory 172 was drawn, It can be determined that the image is drawn around B. Therefore, it can be seen that the perpendicular 178 in the answer drawing is correctly drawn.

  Next, as shown in FIG. 15B, the grader presses the center instruction ○ button 135 to draw a circle 180 centered on the point O, and a part of the circumference is a locus in the answer drawing. The size of the circle is adjusted so as to overlap 182. Here, as shown in FIG. 15B, when a part of the circumference overlaps the locus 182, it can be determined that the locus 182 is drawn with the point O as the center.

  Further, as shown in FIG. 15C, the grader presses the center instruction ○ button 135, draws a circle 184 centering on the intersection B ′ of the locus 182 and the line AB, and The size of the circle is adjusted so that a portion thereof overlaps the locus 186 in the answer drawing. Here, as shown in FIG. 15C, when a part of the circumference overlaps with the trajectory 186, it can be determined that the trajectory 186 is drawn around the point B ′.

  Also, the grader depresses the graphic copy button 139 and copies the circle 184 to draw a circle 188 having the same radius as the circle 184. Then, the scorer moves the circle 188 so that the center point of the circle 188 becomes the intersection D ′ of the trajectory 182 and the perpendicular. Here, as shown in FIG. 15C, when a part of the circumference of the circle 188 overlaps the trajectory 190 that intersects the trajectory 186, the trajectory 190 has the same radius as when the trajectory 186 was drawn, It can be determined that the image is drawn around D ′. Therefore, the line OC in the answer drawing is a line that bisects B′OD ′, and it can be determined that the point C in the answer drawing is correctly drawn.

  Also, the grader can verify the answer drawing of the examinee using the model answer drawing. First, the grader displays an image of the model answer drawing in the display area 132 of the verification screen 130. FIG. 16 is a diagram illustrating an example of an image of the model answer drawing displayed in the display area 132. In FIG. 16, the contour of the image of the answer drawing is indicated by a solid line, and the contour of the image of the model answer drawing is indicated by a broken line. As shown in FIG. 16, the image of the model answer drawing displayed in the display area 132 is different from the image of the answer drawing in the display position and size. Accordingly, as shown in FIG. 17, the grader 130 presses the image movement button 141 and adjusts the display position and size of the image of the model answer drawing so that the image of the model answer drawing overlaps the image of the answer drawing. . Then, by displaying the model answer drawing superimposed on the answer drawing in this way, it becomes possible to verify the answer drawing.

  Here, the size of the image of the model answer drawing needs to be adjusted because the size of the image of the answer drawing displayed in the input image display area 103 may be different depending on the problem and the environment of the scoring device 14. Because there is. Therefore, for example, a mark for measuring the size of the image of the answer drawing is provided in an area in which the answer drawing is filled in the answer sheet, and the adjustment instruction receiving unit 44 uses the mark to measure the image of the answer drawing. The adjustment unit 46 may automatically adjust the size of the image of the model answer drawing in accordance with the size.
