[0003] [Patent Document 1] JP 2016-71517 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned Patent Document 1, the fee for the information medium was calculated by adjusting the actual price of posters at train stations, which have the most experience and track record, according to the type of information medium. However, the fee for the information medium obtained in Patent Document 1 is the commercial value of the information medium determined for the convenience of the information medium provider, and does not take into account the situation of the person viewing the information medium (for example, the amount of contact with information). For this reason, for example, advertisers (users) who use information media to place advertisements, etc., were unable to evaluate whether the fee for the information medium was a fair value.

[0005] Therefore, the main object of the present invention is to contribute to improving the above-mentioned problems. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] This embodiment will be described in detail with reference to FIGS. EXAMPLES

[0010] <Configuration> This embodiment has the following configuration.

[0011] FIG. 1 is a diagram showing the device configuration of an information medium qualitative value calculation device 1. The information medium qualitative value calculation device 1 is a device that calculates the qualitative value of an information medium 2 (FIG. 3), and is equipped with a display unit 3, an input unit 4, and an arithmetic control unit 5. The information medium qualitative value calculation device 1 may be a dedicated machine or a general-purpose machine. The general-purpose machine may be a computer with information medium qualitative value calculation software built in. The computer may be a wide range of devices, including desktop, notebook, tablet, and multi-function mobile terminals such as smartphones.

[0012] The information medium 2 is a display medium used for advertisements and the like. The information medium 2 may be of any type, such as a poster, a billboard, or digital signage. The qualitative value of the information medium 2 is the value of how the information medium 2 appears or the value of its appearance, and is calculated based on the amount of contact with the information medium 2 when a person visually recognizes the information medium 2.

[0013] The display unit 3 is a display such as a liquid crystal panel or an organic EL panel, and performs a display as shown in Fig. 2(a)(b). The input unit 4 is an input device such as a keyboard or a mouse. The input unit 4 may be a touch panel in which a transparent sensor panel is attached to the display unit 3 to allow direct input with a finger or a pen. The calculation control unit 5 is a main part of a computer equipped with a CPU, memory, etc. The information medium qualitative value calculation software is installed in the memory and executed by the CPU. The display unit 3, input unit 4, and calculation control unit 5 may be integrated or separate.

[0014] FIG. 3(a) is a diagram showing an example of the installation of the information medium 2. The information medium 2 is installed, for example, at a corner of an intersection where two roads 6 and 7 intersect. When a passerby is walking in an area c between the shortest distance a at which the entire information medium 2 can be seen on the two roads 6 and 7 and the longest distance b at which the information medium 2 can be effectively seen, the information medium 2 naturally comes into view and the passerby unconsciously sees the entire image of the information medium 2. When the entire information medium 2 comes into view, all of the information is recognized and value is generated. Then, the number of passersby in the above-mentioned area c on the two roads 6 and 7 is counted as the number of people who can come into contact with the information medium 2. On the other hand, passersby outside the above-mentioned area c on the two roads 6 and 7 can only see a part of the information medium 2, so the information medium 2 does not exert its inherent value.

[0015] FIG. 3(b) is a diagram showing the effective visual field 8 of the human eye, with an information medium 2 inside the effective visual field 8. The information medium 2 appears small enough to fit within the effective visual field 8. A virtual reference information medium 9 that fills the effective visual field 8 is also depicted within the effective visual field 8. The appearance of the information medium 2 is more valuable when it appears larger than when it appears smaller. In other words, the appearance of the information medium 2 in the diagram is less valuable than that of the reference information medium 9.

[0016] FIG. 4(a) is a diagram showing the difference in value depending on how the information medium 2 is viewed. Even if the information medium 2 has the same area, the information medium 2 that is close (information medium 2(A)) appears larger, and the information medium 2 that is far away (information medium 2(B)) appears smaller. In addition, the area and appearance of the information medium 2 differ depending on the installation position and installation angle (information medium 2(C)). Therefore, the value of the appearance of the information medium 2 changes depending on the position and angle. That is, as shown in FIG. 4(b), the information medium 2(A) that is close and facing forward has a large area, so the information displayed there is also large, and the amount of contact with the information increases, and the value of the displayed information becomes higher. The information medium 2(B) that is far away facing forward and the information medium 2(C) that is far away facing sideways have a small area, so the information displayed there is also small, and the amount of contact with the information decreases, and the value of the displayed information becomes lower than the value of the information displayed on the information medium 2(A). Therefore, the value of the information medium 2(B) is lower than that of the information medium 2(A).

[0017] FIG. 5 is a plan view of the visual field of a person standing at the center of the width of the passage 11 and facing forward, as seen from directly above. In the figure, the large curve 8a indicates the visual field at the position of the information medium 2, and the small curve 8b indicates the visual field at the position of the reference information medium 9. Line 8c is the right limit line of the visual field (right visual field), and line 8d is the left limit line of the visual field (left visual field). The color discrimination limit of a human visual field is an angle of 60° to the left and right of the center, totaling 120° (effective visual field 8). If the information medium 2 is installed along the passage 11, it will look like line segment 12. If the information medium 2 is installed at an angle to the passage 11, it will look like line segment 13, and from the viewpoint position O (the position of the human eye), it will look like line segment 14 in the visual field (apparent information medium 2). The passage 11 broadly includes above ground, underground, outdoors, and indoors (within a facility).

[0018] FIG. 6 is a side view of the visual field of a person in a standing position, showing a horizontal ground 15, a horizontal eye level 16 representing the height of the person's eyes, and a central line of sight 17. Line 8e is the upper limit line of the visual field (upper visual field), and line 8f is the lower limit line of the visual field (lower visual field). The human visual field has a color discrimination limit of 30° above and below the central line of sight 17, for a total angle of 60° (effective visual field 8). When standing, the normal line of sight is tilted 10° downward from the horizontal to see the feet, so the upper and lower visual fields are 20° above and 40° below the horizontal. The information medium 2 appears to be slightly different in height between the position 18 on the front side and the position 19 on the back side. Note that this information medium 2 is installed tilted from the vertical direction.

[0019] This embodiment has the following configuration. (1) As shown in FIG. 2, the information medium qualitative value calculation device 1 calculates the medium width W of the information medium 2, the medium height H, the passage width L at the viewpoint position O for viewing the information medium 2, the medium installation distance L1 from the viewpoint position O to the information medium 2, the medium installation height h, and the horizontal installation angle θ of the information medium 2. w , vertical installation angle θ h The input section 3 displays the input fields 31 to 37. The information medium qualitative value calculation device 1 includes an input unit 4 for inputting information into input fields 31 to 37 of a display unit 3. The information medium qualitative value calculation device 1 receives the medium width W, medium height H, passage width L, medium installation distance L1, medium installation height h, and horizontal installation angle θ w , vertical installation angle θ h The present invention is provided with an arithmetic and control unit 5 that calculates the ratio of the area of ​​the information medium 2 to a reference area of ​​a reference information medium 9 that is located a reference distance 21 away from the viewpoint position O using the above, and displays the calculated area ratio on the display unit 3 as a qualitative value 38 of the information medium 2.

[0020] Here, the medium width W is the actual horizontal dimension of the information medium 2. The medium height H is the actual vertical dimension of the information medium 2. The viewpoint position O for viewing the information medium 2 is the eye position of a passerby walking in the area c between the two distances a and b in FIG. 3(a) at the center of the width of the passage 11. The qualitative value 38 of the information medium 2 varies depending on the position of the viewpoint position O. The information medium qualitative value calculation device 1 of this embodiment calculates the qualitative value 38 of the information medium 2 at the shortest distance a at which the entire information medium 2 can be seen. The passage width L is the width dimension of the passage 11 where a passerby is walking facing forward. The medium installation distance L1 is the distance from the viewpoint position O to the front of the information medium 2. The medium installation height h is the height from the ground to the top of the information medium 2.

[0021] Horizontal installation angle θ of information medium 2 w is the angle of the information medium 2 with respect to the direction along the passage 11. For example, the information medium 2 installed facing the extension direction of the passage 11 has a horizontal installation angle θ w is 0°, and the information medium 2 that is set in the width direction of the passage 11 has a horizontal setting angle θ w is 90°. Vertical installation angle θ h is the angle of inclination of the information medium 2 in the vertical direction. For example, the information medium 2 that is installed perpendicular to the ground 15 has a vertical installation angle θ h is 90°, and the information medium 2 installed parallel to the ground 15 has a vertical installation angle θ h is 0 degrees or 180 degrees.

[0022] The reference distance 21 is a reference distance for calculating the qualitative value 38 of the information medium 2, and is the distance from the viewpoint position O to the reference information medium 9 (the distance at which the reference information medium 9 appears to fill the effective visual field 8). The reference information medium 9 is a virtual information medium 2 that is used as a comparison target for calculating the qualitative value 38 of the information medium 2. The reference distance 21 and the reference information medium 9 may be selected in any way, but in this example, they are set to a size of 0.9 m and 1 m square. The reference area is the actual area of ​​the reference information medium 9. In this example, the reference area is 1 m2 due to the above. The area of ​​the information medium 2 is the apparent area of ​​the information medium 2 as seen from the viewpoint position O. The area ratio is the ratio of the apparent area of ​​the information medium 2 to the reference area of ​​the reference information medium 9.

[0023] The qualitative value 38 of the information medium 2 is a numerical quantification of the value according to how the information medium 2 appears at the shortest distance at which the entire information medium 2 can be seen. The qualitative value 38 of the information medium 2 is expressed by the term WAI Rating, which is an abbreviation for Apparent Area Index. The display unit 3 is provided with input fields 31 to 37 as well as an output field for the WAI Rating, and displays the calculated qualitative value 38 of the information medium 2.

[0024] (2) Specifically, in the information medium qualitative value calculation device 1, the calculation control unit 5 (A) The distance Dv of the vanishing point 41, which indicates the distance at which the larger of the medium width W and the medium height H becomes indistinguishable, (B) the shortest effective overall visible distance L2 indicating the shortest distance at which the entire information medium 2 can be viewed; (C) The area of ​​the field of view, (D) The apparent area of ​​the information medium 2 is calculated. Then, the calculation control unit 5 (E) calculating the media visual field occupancy rate of the information medium 2 from the apparent area and the visual field area; (F) The ratio of the area of ​​the information medium 2 is calculated from the visual field occupancy rate of the reference information medium 9 and the medium visual field occupancy rate of the information medium 2, and this is taken as the qualitative value 38 of the information medium 2.

[0025] Here, the vanishing point 41 is a point where two distant points become indistinguishable and appear as one, and is generated by the limit of resolution of the human eye. By setting the two distant points to either end of the larger of the medium width W or the medium height H of the information medium 2, the vanishing point 41 becomes a point where the information medium 2 becomes indistinguishable. The vanishing point 41 is set as a virtual point on the center line of the passage 11 (FIG. 5) and at the height of the eye level 16 (FIG. 6). The distance Dv of the vanishing point 41 is the distance from the viewpoint position O to the vanishing point 41. The vanishing point 41 and the distance Dv of the vanishing point 41 are indexes that indicate the change in size of the information medium 2 depending on the distance. The display unit 3 may have an output field 39 that displays the calculated distance Dv of the vanishing point 41.

[0026] 5 and 6 depict a vanishing point 41, and perspective lines that spread out from vanishing point 41 to the left, right, up, and down (right perspective line 41a, left perspective line 41b (Fig. 5), upper perspective line 41c, and lower perspective line 41d (Fig. 6)). Right perspective line 41a and left perspective line 41b extend to both widths of passage 11 at viewpoint position O to form an isosceles triangle. This allows the appearance of information medium 2 to be graphically represented, and qualitative value 38 of information medium 2 can be calculated as a graphical problem using the data entered into input fields 31 to 37 on display unit 3.

[0027] The shortest overall effective visual distance L2 is the distance at which the qualitative value 38 of the information medium 2 is the highest, and corresponds to the distance a in FIG. 3(a). Note that the distance b in FIG. 3(a) may be displayed on the display unit 3 as the longest effective distance. The area of ​​the visual field is the size of the visual field at the position of the information medium 2 when looking forward from the viewpoint position O. The apparent area of ​​the information medium 2 is the size of the information medium 2 that is visible when looking forward from the viewpoint position O. The medium visual field occupancy rate of the information medium 2 is the ratio of the area of ​​the information medium 2 to the visual field area. The visual field occupancy rate of the reference information medium 9 is the ratio of the area of ​​the reference information medium 9 to the visual field area. In FIG. 5 and FIG. 6, the reference information medium 9 is drawn at a position 90 cm in front of the viewpoint position O. The area ratio of the information medium 2 is the visual field occupancy rate ratio of the information medium 2 when the visual field occupancy rate of the reference information medium 9 is 100 (FIG. 2(a)).

[0028] The following is an example of a specific method for calculating the qualitative value 38 of the information medium 2. In Figure 5, The apex angle formed by the left and right perspective lines (right perspective line 41a and left perspective line 41b) is θ1. θ1=2tan -1 (2 x distance Dv of vanishing point 41 / aisle width L). The angle between the right perspective line 41a and the right end of the passage 11 at the viewpoint position O is θ2, and θ2=90-tan -1 (2 x distance Dv of vanishing point 41 / aisle width L). The angle between the line L2 connecting the viewpoint position O and the front end of the line segment 14 representing the apparent information medium 2 and the line segment 14 is θ3, and θ3=180-θi-cos -1 ((L2 2 +L1 2 -(L / 2) 2 ) / (2×L2×L1)). The angle between the line L3, which connects the viewpoint position O and the rear end of the line segment 14 representing the apparent information medium 2, and the line L2 is θ4, and θ4=cos -1 (((L3 2 +L2 2 -W 2 ) / (2×L3×L2). The angle of the apparent information medium 2 on the figure is θ i As a result, θ i =Horizontal installation angle θw-(θ1 / 2). The length of line L2 is L2=√(L1 2 +(L / 2) 2 -(2×L1×(L / 2)cosθ2)). The length of line L3 is L3=√(L2 2 +W 2 -(2×L2×Wcosθ3)). Also, in Figure 6, θ h is 2tan -1 (medium height H of information medium 2 / (2 × distance Dv of vanishing point 41)). ·Angle θ of graphic information medium 2 s θ s = setting angle - θh Let us assume that. The apparent height of the information medium 2 is h, h = H × sin(θ h )

[0029] (A) The distance Dv of the vanishing point 41 is (the length of the long side of the information medium 2)÷tan(1 / visual acuity×1 / 60). Note that the visual acuity used is, for example, 0.7, which is the visual acuity required for renewal of a Class 1 driver's license for ordinary motor vehicles.

[0030] (B) The shortest overall effective visibility distance L2 is (= (2.745 × visibility height limit) - 4.1212).

[0031] For example, as shown in FIG. 7(a), the information medium 2 was installed on the vertical side of a building 45 so that the top edge was 2.1 m above the ground, and the information medium 2 was shown to a person with an eye level (eye level 16) of 1.5 m. The shortest distance at which the entire information medium 2 was visible (shortest overall effective visibility distance L2) was then investigated. Similarly, the shortest overall effective visibility distance L2 was investigated by changing the installation height of the information medium 2 in various ways. The results were as shown in the table of FIG. 7(b). This table was then compiled into a graph as shown in FIG. 7(c). This confirmed that the shortest overall effective visibility distance L2 and the visibility height limit are proportional to each other. The above formula was obtained from this graph. In this case, as mentioned above, the human visual field has a color discrimination limit of 30° above and below, and when standing, the normal line of sight is 10° downward from the horizontal, so the upward direction is 20° from the horizontal. Therefore, the visibility height limit is (=(0.364 x distance) + 1.5) (0.364 = tan 20°).

[0032] (C) The area of ​​the field of view is (= the width of the field of view Sw × the height of the field of view Sh). In this case, The field of view width Sw is Sw=(2×(√(L1 2 +(L / 2) 2 -(2L1×(L / 2) ×cosθ2)×Π)×120 / 360. The vertical width of the field of view, Sh, is Sh=(2×(√(L1 2 +(L / 2) 2-(2L1×(L / 2) ×cosθ 2 )×Π)×60 / 360.

[0033] (D) The apparent area of ​​the information medium 2 is (=(apparent height Hf on the front side + apparent height Hb on the back side) × apparent medium width Wa / 2). In this case, The apparent height Hf on the front side is Hf=2×(Dv-L1)×tan(θ h / 2). The apparent height Hb at the back side is Hb=2×(Dv-L1-W)×tan(θ h / 2). The apparent media width Wa is, as shown in FIG. 5, Wa=2×L2×sin(θ4 / 2).

[0034] (E) Media view fraction is (= (D) apparent area / (C) view area). As can be imagined from FIG. 3(b), the visual field occupancy rate of the reference information medium 9 is 43.42.

[0035] The area ratio of the (F) information medium 2 is (= ((E) medium visual field occupancy rate / visual field occupancy rate of reference information medium 9) × 100). The qualitative value 38 of the information medium 2 is then (WAI Rating = area ratio of the information medium 2), and is displayed in the output field of the display unit 3.

[0036] <Functions and Effects> The functions and effects of this embodiment are as follows. (Effect 1) In the information medium qualitative value calculation device 1, the display unit 3 displays the medium width W of the information medium 2, the medium height H, the passage width L of the viewpoint position O for viewing the information medium 2, the medium installation distance L1 from the viewpoint position O to the information medium 2, the medium installation height h, and the horizontal installation angle θ of the information medium 2. w , vertical installation angle θ hThe input unit 4 displays input fields 31-37 of the display unit 3. An operator uses the input unit 4 to input data into the input fields 31-37 of the display unit 3. Each input by the input unit 4 is displayed in the input fields 31-37. The calculation control unit 5 controls the display processing of the display unit 3 and the input processing by the input unit 4 into the input fields 31-37 of the display unit 3. The calculation control unit 5 also controls the medium width W, medium height H, passage width L, medium installation distance L1, medium installation height h, horizontal installation angle θ, and the like input to the input unit 4. w , vertical installation angle θ h Using this, the ratio of the area of ​​the information medium 2 to the reference area (1 square m) of a reference information medium 9 (e.g., 1 m square) located a reference distance 21 (e.g., 0.9 m) away from the viewpoint position O is calculated, and the calculated area ratio is displayed on the display unit 3 as the qualitative value 38 of the information medium 2.

[0037] In this way, the information medium qualitative value calculation device 1 accurately quantifies (quantifies) the value of the information medium 2 to the viewer (qualitative value 38) based on ergonomics. Because the qualitative value 38 of the information medium 2 is a concrete, objective numerical value, the merits or demerits of the qualitative value 38 of the information medium 2 are visualized. Thus, the numerical value of the qualitative value 38 of the information medium 2 becomes a new indicator regarding the information medium 2. By using this numerical value of the qualitative value 38, for example, a trader can make a plan for installing the information medium 2, decide whether or not to invest in it, and also correctly evaluate and select the information medium 2 when purchasing the information medium 2.

[0038] (Effect 2) In the information medium qualitative value calculation device 1, the calculation control unit 5 calculates the distance Dv of the vanishing point 41 indicating the distance at which the larger of the medium width W and medium height H becomes unrecognizable, the shortest overall effective visible distance L2 indicating the shortest distance at which the entire information medium 2 is visible, the field of view area, and the apparent area of ​​the information medium 2. Then, the calculation control unit 5 calculates the medium field of view occupancy rate of the information medium 2 from the apparent area and the field of view area, and calculates the ratio of the area of ​​the information medium 2 from the field of view occupancy rate of the reference information medium 9 and the medium field of view occupancy rate of the information medium 2 to obtain the qualitative value 38 of the information medium 2.

[0039] This allows the information medium qualitative value calculation device 1 to calculate a qualitative value 38 according to the appearance of the information medium 2. For example, in the case of information media 2 of the same area, objects closer to the viewpoint position O appear larger and objects further away appear smaller, and the information medium qualitative value calculation device 1 calculates the qualitative value 38 of the information medium 2 to be a numerical value according to such appearance.

[0040] Furthermore, when the target information medium 2 is placed in front of the viewpoint position O, the information medium 2 appears rectangular and its visible area is large, but the information medium qualitative value calculation device 1 calculates the numerical value of the qualitative value 38 as a large value. In contrast, when the target information medium 2 is placed on the side of the passage 11 with respect to the viewpoint position O, the information medium 2 appears trapezoidal due to perspective and its visible area is small, but the information medium qualitative value calculation device 1 calculates the numerical value of the qualitative value 38 as a small value. Therefore, the information medium qualitative value calculation device 1 evaluates the qualitative value 38 of the information medium 2 more accurately and in detail.

[0041] The qualitative value 38 of the information medium 2 obtained by the information medium qualitative value calculation device 1 can be used as follows. "Requirements for calculating the objective price and value of information media 2" For example, even if a large information medium 2 is installed, if the information medium 2 is installed in a position that makes it difficult to see, a problem will occur in visibility. The qualitative value 38 of the information medium 2 can quantify this problem.

[0042] "Objective comparative verification of multiple similar information media2" For example, it is possible to specifically check information media 2 that are expensive but have a low WAI rating, or conversely, information media 2 that are cheap but have a high WAI rating. Therefore, the qualitative value 38 of the information medium 2 can be used as a guide for selecting the information medium 2.

[0043] "An objective, numerically based survey of the locations and positions where information media 2 can be effectively installed and viewed." Since the number of pedestrians who can come into contact with an information medium 2 is determined by its location, installation environment, etc., the qualitative value 38 of the information medium 2 can be used to measure or calculate the number of people who can come into contact with the information medium 2.
