Description

  The present invention relates to an evaluation apparatus, an evaluation method, and a program, and more particularly to layout evaluation of display information.

  In the screen design of the system, the listability of information on the screen is an important index, and various ideas have been made to improve the listability of information. Many techniques for improving the listability by using special expressions such as 3D (Three-Dimensional) expression and superposition and transmission have been proposed.

  When considering the layout of information, it is necessary to consider not only listability but also visibility or operability. For example, text size and line break margins are adjusted appropriately according to the user to improve visibility, or liquid layout is used to improve operability in order to avoid the occurrence of horizontal scrolling. Can be devised. Liquid layout is a technology that adjusts the information layout in the middle according to the width and makes a line feed.

  On the other hand, for a system user, even if the amount of information displayed on the screen is large, the listability of information does not increase. Even if a large amount of information is simply displayed on the screen, depending on the display state, there is a possibility that the user's work may be hindered only by making the screen complicated. For example, when only a part of certain information is visible on the screen, the information may not be meaningful to the user (cannot understand the contents), and it may interfere with the reference to other information. End up. Therefore, when the information does not fit on the screen, it is important to consider the listability for each information group (block) on the screen. An information group means a group of information that is a target of a user's business or purpose.

  As a related technique, Patent Document 1 describes a method for determining and generating an information layout so that a user's specification description in an interface is minimized. The technique of Patent Document 1 has a function of determining the quality of layout for each block when determining and generating a layout, and evaluates the quality of the layout according to prescribed guidelines and restrictions. The technique of Patent Document 1 uses (1) a wasted space (WS) and (2) a balance of fields in an object block (B) as an index for quality evaluation. Evaluate whether it can be used and determine the layout.

  As another related technique, Patent Document 2 describes a portlet layout setting on a portal screen. The technique of Patent Document 2 adjusts each portlet and its internal information display in order to avoid the occurrence of scrolling and loss of important information when the amount of information on the portal screen is large.

JP-A-6-208592 Japanese Patent Laid-Open No. 2004-252688

  When various types of information are arranged in areas on the screen, it is difficult to determine the layout of each area in consideration of the listability of the area. This is more noticeable on screens where there are multiple areas (windows, portlets, boxes, etc.) such as operation management screens and electronic medical record screens, and users need to refer to a large amount of information at once. .

  In the technology of Patent Document 1, when determining and generating a layout, as a quality evaluation of the layout for each block, it is considered how much the block is utilized without waste, considering the space consumed and the balance of fields in the block. Evaluating. However, the technique of Patent Document 1 is assumed only when all fields can be arranged in a block (when scrolling does not occur). In other words, it is impossible to evaluate the listability when information is hidden outside the area. In other words, it is impossible to know the degree of inhibition of the listability due to hidden information.

  Furthermore, the technique of Patent Document 1 evaluates the block consumption space using the minimum rectangular area that can surround the data field and the sum of the field areas. However, in the technique of Patent Document 1, in order to ensure the visibility and relationship of information, a case where a designer intentionally provides a line break or a margin, and a wasteful space as a result of automatic line break by a liquid layout. Cannot be determined.

  Furthermore, the technology of Patent Document 2 arranges portlets on the display area and adjusts the size of each portlet, so that important information may go out of the display area, or some portlet display areas. Is prevented from being sufficiently secured. However, when the number of portlets and the amount of information in the portlet increase, important information cannot be seen. That is, the technique of Patent Document 2 does not consider at all how information in each portlet is displayed.

  As described above, the techniques of Patent Documents 1 and 2 provide information for quantitatively evaluating the listability of an area and the listability of blocks in the area in an arbitrary area during layout evaluation of display information. Can't get.

  The objective of this invention is providing the evaluation apparatus for solving the said subject.

<First Embodiment>
An evaluation apparatus according to a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the evaluation apparatus according to the first embodiment. The evaluation device 10 includes a calculation unit 3 and a drawing unit 4. In addition, an input device 1, a storage device 2, and an output device 5 are connected to the evaluation device 10. Each configuration will be described below.

(Input device)
The input device 1 has a function of inputting screen information related to information displayed on the evaluation target screen. The input screen information is sent from the input device 1 to the evaluation device 10.

  FIG. 2 is a diagram illustrating an example of an evaluation target screen of the evaluation apparatus. The evaluation target screen 15 that is evaluated by the evaluation device 10 includes at least one area. The evaluation target screen 15 shown in FIG. 2 has three areas for displaying information, and are divided into Area 01, Area 02, and Area 03, respectively. There is at least one block in each area. There are two blocks in Area01, one block in Area02, and two blocks in Area03.

  Note that the areas in the present embodiment may be called windows, portlets, and boxes on the screen.

  FIG. 3 is an explanatory diagram showing the display status of blocks in Area 01 on the evaluation target screen. Area 01 has an area having an area width W 01 and an area height H 01, and has two blocks, block 01 (broken line rectangle) 201 and block 02 (broken line rectangle) 202. Each of the block 01 and block 02 information shown in FIG. 3 represents a character. In FIG. 3, all the character information in block 01 is displayed on the screen and is divided into paragraphs by line feeds. In block 01, there are two line breaks, a final line width W211 and a final line width W212. On the other hand, for block 02, only the first part of block 02 is displayed on the screen, and the remaining information is not displayed on the screen.

  FIG. 4 is an explanatory diagram showing an example of screen information of the evaluation target screen 15 shown in FIG. The screen information is information (area information) related to each area constituting the screen. For each area, the area ID for identifying the area, the width and height of the area, and the block of information displayed in the area are identified. Block ID to be included. As an example of the area information shown in FIG. 4, Area 01 has an area width of 300 pixels (hereinafter referred to as px) and an area height of 900 px. Moreover, Area01 has block01 and block02 as a classification of information to be displayed in Area01. In addition to the above, the area information may include information such as area coordinates, importance of each area, usage frequency, presence / absence of scrolling, and the like.

  Further, the screen information includes block information as information regarding each block in each area. The block information includes a block ID for identifying the block, a display amount displayed in the block, an information amount of the entire block, a line feed information indicating the line feed position of the block and the width of the last line. In the example of the block information shown in FIG. 4, the display amount of 7 lines displayed in block01 is equal to the information amount of 7 lines of the entire block. This means that all information is displayed in block01. On the other hand, in block 02, the information amount is 5 rows with respect to the display amount of 1 row. This means that in block 02, one line is displayed on the screen and four lines are not displayed on the screen.

  In addition, as the line feed information of the block of block 01, it represents that there are two line feeds (4, 200) and (7, 15) in the block. The line feed information (4,200) indicates that the line feed is on the fourth line of block 01 and the final line width (final line width W211 in FIG. 3) is 200 px. (7, 15) means that the line break is on the seventh line of block 01 and the final line width (W212 in FIG. 3) is 15 px.

  In the above example, the amount of information is indicated by the number of lines that is one of the character information, but height information may be used in the case of an image or a graph. Moreover, although the final line width is shown as an example assuming the number of pixels, the number of characters may be used. In addition, as the block information, information importance for each block (relative comparison with other blocks), font size, margin designation, and the like may be provided.

(Storage device)
The storage device 2 has a function of storing an evaluation rule for the evaluation device 10 to evaluate the evaluation target screen. The evaluation rule is a calculation formula for calculating the evaluation value of the listability of the area or block, and includes a calculation formula for usability and a calculation formula for line feed influence. Here, the calculation formula of usability is an expression that calculates how useful the information displayed on the screen is for the viewer based on the display rate of each block in the area on the evaluation target screen 15 as an evaluation value. . In addition, the calculation formula for the line feed effect is a formula that calculates the influence of the reduction of the displayable area due to the blank area in the block caused by the useless line feed as an evaluation value based on the area width and the line feed position of the text in the block. .

An example of a usefulness calculation formula is shown in Formula 1.

The function f (x) shown in Expression 1 is a function for calculating an evaluation value of usefulness for the viewer based on the desired block display rate x. FIG. 6 is a graph of the function f (x) shown in Equation 1. For example, if all the information is displayed in a desired block on the screen, the display rate x = 100%, and the usability evaluation value is f (x) = 100. When only a part of the block is displayed on the screen, for example, when the display rate x = 20%, the usefulness evaluation value is f (x) = − 20. The reason why the usefulness evaluation value of the function f (x) is a negative value is that when the display rate of the blocks in the area is low, the information is not meaningful to the viewer of the screen, but other information It is because the point which obstructs the listability of is considered. Note that the function f (x) shown in FIG. 6 uses a linear function, but may use a nonlinear function or a stepped function.

Next, an example of an expression for calculating the evaluation value of the line feed effect is shown.

w: Area width (number of pixels)
m: length of the last line (number of pixels)
y: Number of useless line breaks satisfying a predetermined condition (m / w <= 10 (%)) in the block. In this example, the length of the last line (number of pixels: m) is the width of the area (number of pixels). : If the ratio is less than the standard (for example, 10% or less) compared to w), the corresponding part is regarded as a “useless line feed”, and the number of useless line feeds y is set to a prescribed number (eg, −5). )). In addition to using the ratio between the length of the last line and the area width as described above, it is possible to determine “useless line feed” based on the number of characters in the text on the last line, A calculation formula in which the deduction point becomes larger as the length of the line feed is shorter may be used.

  As the evaluation rule, a formula for multiplying the calculated usability evaluation value and the calculated line feed effect evaluation value by a predetermined prescribed weight may be used separately. Moreover, as an evaluation rule, in addition to usability and line feed influence, the font size or line spacing may be too narrow (width too narrow), the same information may be displayed repeatedly, and the like.

(Calculation unit)
Next, the calculation unit 3 of the evaluation device 10 acquires area information and block information of a predetermined area from the input device 1, and further acquires a listability evaluation rule from the storage device 2. The predetermined area may be a partial area of information displayed on the evaluation target screen, or may be all areas. Further, the predetermined area may be an area designated by the operator of the evaluation device 10 via the input device 1.

  With reference to the area information and block information in the predetermined area acquired from the input device 1 and the list property evaluation rule acquired from the storage device 2, the evaluation value of the list property is calculated for each block in the predetermined area. The calculation unit 3 refers to the block ID included in the area information when calculating the evaluation value of the listability of the block, and identifies the block existing in the predetermined area.

Subsequently, the calculation unit 3 calculates the evaluation value of the listability of a predetermined area based on the calculated evaluation value of the listability for each block. The calculation of the evaluation value of the listability of the area is obtained by the average of the calculated evaluation values of the listability of each block, as shown in Equation 3.
Evaluation value of area listability = [Σ {(evaluation value of listability of block i)] / i −− (formula 3)
In calculating the evaluation value of the listability of the area, the information indicating the importance of the block is included in the block information as shown in Equation 4, and this is used as the weight of the evaluation value of the listability of each block. An evaluation value may be calculated.
Evaluation value of area listability = [Σ {(evaluation value of listability of block i) × wi}] / i− (formula 4)
wi: Importance (%) of block i (Σwi = 1) (i is a natural number of 1 or more)
As another example of calculating the area listability, if the area information includes horizontal scrolling information and there is horizontal scrolling, points may be deducted from the evaluation value of the area listability according to the specified value. .

(Drawing part)
The drawing unit 4 of the evaluation device 10 generates drawing data to be displayed on the output device 5 based on the evaluation results of the listability of each area and each block output by the calculation unit 3, and the generated drawing data Is sent to the output device 5.

(Output device)
The output device 5 displays the area and the drawing data of the evaluation result of the listability of the blocks sent from the drawing unit 4 of the evaluation device 10 on the screen.

  FIG. 6 is a block diagram illustrating a modification of the evaluation apparatus according to the first embodiment. An evaluation apparatus 10A shown in FIG. 6 is different from the above-described evaluation apparatus 10 in that the storage device 2 is arranged inside the evaluation apparatus 10A and connected to the calculation unit 3. As shown in FIG. 6, the storage device 2 may be arranged inside or outside the evaluation device.

  Next, operation | movement of the evaluation apparatus 10 by 1st Embodiment is demonstrated using drawing. FIG. 7 is a flowchart showing the operation of the evaluation apparatus 10 according to the first embodiment. As shown in FIG. 7, first, screen information related to the evaluation target screen is input to the input device 1, and the input device 1 outputs the input area information and block information to the evaluation device 10. The calculation unit 3 of the evaluation device 10 acquires area information and block information from the input device 1, and acquires an evaluation rule for calculating evaluation values for the listability of areas and blocks from the storage device 2 (S11). .

  Next, the calculation unit 3 calculates an evaluation value of the list property of areas and blocks (S12). FIG. 8 is a flowchart showing a subroutine process for calculating an evaluation value of the listability of areas and blocks. The calculation unit 3 refers to the area information and block information of the predetermined area, and specifies the block displayed in the predetermined area (S21). Next, the calculation unit 3 refers to the evaluation rule for each identified block and calculates an evaluation value of the listability of each block (S22).

  The calculation unit 3 calculates the evaluation value of the usefulness of the block as one of the evaluation values of the listability of the block. The calculation unit 3 obtains the display rate x (%) in the block from the display amount included in the area information and the information amount, and determines the block rate from the relationship with the usability function f (x) shown in Equation 1 (FIG. 5). A usefulness evaluation value is calculated.

  Furthermore, the calculation unit 3 calculates the evaluation value of the line feed effect in the block as one of the evaluation values of the listability of the block. When a line break is included in each block, the calculation unit 3 determines whether the line break affects the screen display (whether the line break is a useless line feed). A value obtained by multiplying the value by a specified value (for example, −5) is used as the evaluation value of the line feed effect. If there is no line break, the evaluation value for the line break effect is zero. The calculation unit 3 calculates the evaluation value of the block listability by adding the evaluation value of the usefulness of the block and the evaluation value of the line feed effect.

  After calculating the evaluation value of the listability of all blocks in the predetermined area (Yes in S23), the calculation unit 3 evaluates the listability of the predetermined area based on the calculated evaluation value of the listability of the block. The value is calculated (S24), and the subroutine process is exited. The calculation unit 3 passes the calculated evaluation values of the list properties of the areas and blocks to the drawing unit 4.

  The drawing unit 4 of the evaluation device 10 generates drawing data based on the evaluation value of the listability of the area calculated by the calculation unit 3 and the evaluation value of the listability of the block (S13), and draws on the output device 5. Output data. The output device 5 displays the evaluation result by the evaluation device 10 on the screen based on the drawing data.

  FIG. 9 is a block diagram showing a minimum configuration for solving the problems of the present invention with respect to the evaluation apparatus 10 according to the first embodiment. The evaluation device 10 includes a calculation unit 3, and the calculation unit 3 first acquires area information of an area constituting the screen and block information indicating a display state of blocks in the area, and evaluates block listability. Get an evaluation rule to calculate a value. The calculation unit 3 calculates the evaluation value of the listability for each block in the area based on the acquired various information and the evaluation rule. Furthermore, the calculation unit 3 calculates the evaluation value of the listability of the area including the block based on the calculated evaluation value of the listability for each block. As described above, the evaluation apparatus 10 can calculate the evaluation value of the listability of the area and the evaluation value of the listability of the blocks in the area, and quantitatively determine the listability of the area and the listability of the blocks in the area. Can provide information to evaluate.

  Further, according to the evaluation device 10 of FIG. 1 and the evaluation device 10A of FIG. 6, the drawing unit 4 draws drawing data based on the evaluation results of the listability of each area and block calculated by the calculation unit 3 of the evaluation device 10. Can be created. Thereby, the operator of the evaluation apparatus 10 can easily grasp the problem and the extent of each area on the evaluation target screen, which is useful for examining the improvement policy for the optimal layout of information on the evaluation target screen. be able to.

  Further, the operator of the evaluation device 10 inputs screen information for improving the displayed problem to the input device 1 so that the evaluation device 10 evaluates a predetermined area again. It is possible to determine the optimal layout of the.

Example 1
Next, as Example 1 of the first embodiment, calculation of evaluation values for listability of areas and blocks using the evaluation apparatus 10 and drawing of evaluation results will be described. In addition, the screen evaluated by the evaluation apparatus 10 of Example 1 is the evaluation target screen 15 illustrated in FIG. 2, and the screen information of the evaluation target screen 15 includes the area information and the block information illustrated in FIGS. 3 and 4. Use.

  First, the operator of the evaluation apparatus 10 inputs the area information related to Area 01 and the block information among the screen information shown in FIG. The input device 1 outputs the input area information and block information to the evaluation device 10. The evaluation device 10 receives area information and block information related to Area01 from the input device 1.

  The calculation unit 3 of the evaluation device 10 refers to the area information and block information of Area01 and identifies block01 and block02 as the blocks displayed on Area01.

  Next, the calculation unit 3 refers to the list property evaluation rule held by the storage device 2 for each identified block 01 and block 02, and calculates an evaluation value of the block list property.

  First, the calculation unit 3 calculates a list property evaluation value of block01. In block 01, since the display amount and the information amount are both 7 lines, the display rate x is 100%. As a result of input to the usability function f (x) shown in Equation 1 (FIG. 9), the usefulness evaluation value of block01 is calculated as 100.

  Subsequently, the calculation unit 3 determines whether or not the line breaks are useless line breaks for the two line break positions included in block01. First, the calculation unit 3 has a final line width of 200 px and a ratio of the area 01 width of 300 px exceeds a specified value (10%) with respect to the line feed position of the fourth line, which is the first line feed of block01. Judge that it is not a useless line feed.

  Next, since the final line width is 15 px and the width of Area 01 is 300 px, the calculation unit 3 uses the area up to the line break position for the line break position of the seventh line, which is the second line break. 5%. For this reason, the calculation unit 3 determines that the second line break that falls below the specified value 10% is a useless line break. As a result of the line break determination in block 01, the calculation unit 3 applies Equation 2 and multiplies the number 1 of useless line breaks by the specified value (−5) to calculate −5 as the evaluation value of the line break effect. The calculation unit 3 calculates “95” obtained by adding the evaluation value “−5” of the line feed effect to the evaluation value “100” of usability as the evaluation value of block01 listability.

  Next, the calculation unit 3 calculates the evaluation value of the list property of block02. In block 02, since the display amount is 1 and the information amount is 5, the display rate x is 20%. As a result of the input to the usability function f (x) shown in Expression 1 (FIG. 9), the usefulness evaluation value of Block02 is calculated as −20.

  Subsequently, the calculation unit 3 determines whether or not the line break of block 02 is a useless line feed. Since block 2 has no information on the line feed position, the evaluation value for the line feed effect is not calculated. As a result, the calculation unit 3 calculates −20 as the evaluation value of the list property of block02.

  Subsequently, the calculation unit 3 calculates the evaluation value of the listability of the area using the listability result for each block. From the evaluation value 95 of the list property of block 01 and the evaluation value -20 of the list property of block 02, the calculation unit 3 obtains the evaluation value of the list property of Area 01 as 37.5 as a total average.

  Next, the drawing unit 4 of the evaluation device 10 draws the evaluation value of the area listability calculated by the calculation unit 3 and the evaluation value of the block listability as an evaluation result.

  10A and 10B are schematic diagrams illustrating display examples of the evaluation result of Area 01 by the drawing unit 4. As illustrated in FIG. 10A, the drawing unit 4 represents the relationship between areas and blocks in a hierarchical structure (two-grid), and displays the evaluation results of listability corresponding to the areas and blocks for each layer in numerical values and bar graphs. For the display of the evaluation result, other expressions such as a table or a list may be used, or the evaluation result may be displayed superimposed on the evaluation target screen.

  The drawing unit 4 can also change the color or pattern of the bar graph according to the numerical value of the evaluation result. For example, when the evaluation value is negative, it is possible to use a color having a high contrast ratio with the background color for the problematic bar graph because there is a problem. Moreover, you may display with the color which alerts a viewer like red or yellow.

  In addition, an icon, a symbol, or a message may be displayed on the screen to indicate to the viewer whether or not there is a problem with the listability evaluation result and to what extent. FIG. 10B is a schematic diagram showing a message displayed when a bar graph of an area or block is selected (mouse over). In FIG. 10B, as the details of the selected bar graph (evaluation result of block 01), supplementary information of the evaluation value of the usefulness of information and the evaluation value of the influence (use efficiency of area) due to useless line spacing is displayed. In the above example, it is assumed that information related to the evaluation result is displayed on the chip help when the mouse is over. However, the present invention is not limited to this. The original evaluation result may be displayed in accordance with the display screen.

  According to the evaluation device 10 of the first embodiment, the drawing unit 4 draws the evaluation value of the listability of each area and block calculated by the calculation unit 3 of the evaluation device 10, so that the operator of the evaluation target screen can In addition, regarding the listability of blocks, the presence or absence of the problem or the degree thereof can be determined.

  Furthermore, the operator of the evaluation device 10 inputs screen information for improving the problem into the input device 1 so that the evaluation device 10 evaluates a predetermined area again. It is possible to determine a proper layout.

(Example 2)
Next, in the second embodiment, according to the evaluation result of the list property of the areas and blocks calculated by the evaluation device 10, the operator of the evaluation device 10 obtains screen information (area information and block information) regarding the area as an improvement policy. This is an example of input.

The input device 1 outputs screen information (area information, block information) regarding the input area to the calculation unit 3 of the evaluation device 10. The calculation unit 3 refers to the area information and block information of each area received from the input device 1 and calculates a list property evaluation value of each area.
As a calculation result of the calculation unit 3, the evaluation value of the list property of Area01 is 37.5 similarly to the first embodiment. In addition, the evaluation value of the listability of Area 02 and Area 03 is 100 because all blocks are displayed in each area on the screen and there is no useless line feed.

  The drawing unit 4 outputs the evaluation results of the listability of Areas 01 to 03 and blocks 01 to 05 to the monitor screen that is the output device 6.

  Next, the operator of the evaluation device 10 refers to the evaluation result of the listability of Area01 and examines a further screen improvement policy. For example, as an improvement policy, in order to eliminate useless line breaks in block 01 in Area 01, the width of Area 01 may be widened, or the height of Area 01 may be increased in order to increase the evaluation value of the list property of block 02. . Conversely, if only a part of block02 is displayed, the screen becomes complicated, and the height of Area01 may be reduced. An operator of the evaluation device 10 inputs area information and block information to the input device 1 in accordance with some improvement policies. The evaluation device 10 evaluates the area listability again for each improvement policy, so that the operator of the evaluation device 10 can derive the optimum solution for the size of each area. The evaluator of the evaluation apparatus 10 inputs the area information and block information for all the areas displayed on the screen, thereby listing the effects on the other areas due to the size change of a certain area in each area. It can be adjusted while confirming the evaluation of sex.

  Here, the influence on other areas when the size (width or height) of a certain area is changed in the evaluation target screen will be described. FIG. 11A is a schematic diagram showing the influence on Area 02 when the size (width) of Area 01 is changed. For example, as shown in FIG. 11A, by increasing the width of Area01 (rectangle 70), the listability of Area01 is greatly improved, but the width of Area02 (rectangle 71) in the vicinity is narrowed and the listability is reduced. Is output. FIG. 11B is a schematic diagram illustrating the effect on Area 03 when the size (height) of Area 01 is changed. As shown in FIG. 11B, by increasing the height of Area01 (rectangle 72), the listability of Area01 is greatly improved, but the width of Area03 (rectangle 73) is reduced and the listability of Area03 is greatly reduced. It will be.

  FIG. 11C is a schematic diagram illustrating the effect on Area 02 when the size (width) of Area 01 is changed. As shown in FIG. 11C, by increasing the width of Area01 (rectangle 74), useless line breaks in block01 of Area01 are eliminated, and the amount of information displayed in block02 of Area01 is slightly increased. As a result, the display listability of Area01 is improved. At this time, the width of the area 02 (rectangle 75) is reduced as an effect on the area 02 due to the change in the size of the area 01, but the evaluation device 10 does not cause the operator to generate an optimal solution that does not cause scrolling. Can provide information to determine

  As described above, according to the evaluation device 10 of Example 2 according to the first embodiment, the drawing unit 4 draws the evaluation value of the listability of each area and block calculated by the calculation unit 3 of the evaluation device 10. The operator of the evaluation apparatus 10 can grasp the problem and the degree of each area.

  Furthermore, the operator of the evaluation device 10 inputs screen information for improving the problem into the input device 1 so that the evaluation device 10 evaluates a predetermined area again. It is possible to determine a proper layout. Even if an operator who does not have specialized knowledge or experience regarding usability operates the evaluation apparatus, it is possible to determine whether or not there is a problem in the listability for each area and each block.

<Second Embodiment>
Next, an evaluation apparatus according to a second embodiment of the present invention will be described with reference to the drawings. FIG. 12 is a block diagram showing a configuration of the evaluation apparatus 10B according to the second embodiment. The evaluation device 10B according to the second embodiment is different from the evaluation device 10 according to the first embodiment in that the calculation unit 3B includes a selection unit 31. The block information of the second embodiment is different in that information indicating the use / type of the block is added to the block information.

  Hereinafter, the evaluation device 10B according to the second embodiment will be described focusing on differences from the evaluation device 10 according to the first embodiment.

  First, the input device 1 receives screen information (area information, block information) related to the evaluation target screen. Of the screen information, the block information includes information indicating the use / type of the block. The input device 1 outputs the received screen information to the evaluation device 10B.

  FIG. 13 is an explanatory diagram showing block information sent from the input device 1 to the evaluation device 10B. In the block information shown in FIG. 13, “transverse direction” is given to block 02 as information indicating the use / type of the block.

  The information indicating the use / type of the block includes “vertical direction”, “must display all”, or “input” in addition to “horizontal direction”. “Vertical direction”, “Horizontal direction”, and “Mandatory display required” indicate the type of display information of the block, and “For input” indicates the use of the display information of the block.

  An example of use / type block information will be described with reference to FIGS. 14A, 14B, and 14C. FIG. 14A is a diagram for explaining the “vertical direction” of the block type. In the block 81 shown in FIG. 14A, the label name of the graph and the length of the graph are arranged in the vertical direction. That is, the connection of information in the block 81 is in the vertical direction. For this reason, when only a part of the block 81 in the height direction is displayed on the screen, the block 81 is likely to be information that is meaningless to the viewer. Therefore, when the graph as shown in the block 81 is included as the display information of the block, it is necessary to consider the display in order to increase the usefulness for the viewer of the screen. In addition to the example of the graph in the vertical direction, the type of the block is “vertical direction” when the text is vertically arranged, such as vertically written Japanese text or Chinese text.

  FIG. 14B is a diagram for explaining the “horizontal direction” of the block type. In the block 82 shown in FIG. 14B, the label name of the graph and the length of the graph are arranged in the horizontal direction. That is, the connection of information in the block 82 is in the horizontal direction. For this reason, if only a part of the width direction of the block 82 is displayed on the screen, the length of the graph may not be read or the label name may not be visible, which may result in meaningless information for the viewer of the screen. high. In the case of lists and tables in addition to horizontal graphs, the block type is “horizontal”.

  FIG. 14C is a diagram for explaining the block type “whole display mandatory”. A block 83 shown in FIG. 14C is a pie chart, and the data distribution is the entire block. Therefore, if the information in the block cannot be listed, there is a high possibility that the information becomes meaningless to the viewer of the screen. In addition to the pie chart, the map also corresponds to the information in the block being “required to display all”.

  Next, “input” which is one of the uses of the block will be described. This is a general block for the viewer to input or select information in the display area of the screen. Even if not all of the input fields can be listed, if it is possible to confirm before and after the item to be input, there is a high possibility that it will be sufficient for the user.

  In addition to the use and type, more detailed classification designation may be provided in consideration of the meaning of each display information on the evaluation target screen or business requirements for the display information.

Next, the storage device 2 of the evaluation device 10 </ b> B uses the usage / type included in the block information as an equation for calculating the usefulness evaluation value in addition to the equations 1 and 2 described in the first embodiment. Corresponding equation 5 is provided. Expression 5 shown below is an expression corresponding to the “horizontal direction” among the uses / types included in the block information.

The function f ₂ (x) is an expression for calculating the usefulness for the viewer of the screen according to the display rate x of the block. FIG. 15 is a diagram for explaining the function f ₂ (x) shown in Expression 5. The function f ₂ (x) shown in FIG. 15 calculates a positive value as an evaluation value of usefulness when the display rate x is 0% or more and 50% or less, and when the display rate x exceeds 50 and 100% or less, A constant value 100 is calculated as a usefulness evaluation value.

  Similar to the first embodiment, the calculation unit 3B of the evaluation measure 10B refers to the area information and block information received from the input device 1 and the evaluation rules for the listability held by the storage device 2, and lists the area listability. Evaluation value of block and evaluation value of listability of block are calculated.

The calculation unit 3B includes a selection unit 31 that selects an expression for calculating the evaluation value of the usefulness of the block. When calculating the usefulness of a block, the selection unit 31 of the calculation unit 3B checks the presence / absence of block usage / type information as block information of the block. When there is no block usage / type information, the selection unit 31 selects the function f (x) of Formula 1 as a formula for calculating usefulness. When there is block usage / type information, A function f ₂ (x) of 5 is selected.

  The calculation unit 3B calculates the evaluation value of the usefulness of the block using the calculation formula of the usefulness selected according to the presence / absence of the usage / type information in the block information, and adds the evaluation value of the block line feed effect Then, the evaluation value of the list property of the block is calculated. Subsequently, the calculation unit 3B calculates an evaluation value of the listability of the area based on the calculated evaluation value of the listability of the block.

  The calculation unit 3B sends the calculated evaluation value of the list property of the area and the block to the drawing unit 4, and the drawing unit 4 is based on the evaluation value of the list property of the area and the block, as in the first embodiment. Generate drawing data.

  Hereinafter, an example of calculating the evaluation value of the list property of areas and blocks by the calculation unit 3B of the evaluation apparatus 10B will be described using the area information illustrated in FIG. 4 and the block information illustrated in FIG.

  First, the calculation unit 3B refers to the area information and the block information, and identifies block01 and block02 as the blocks displayed in Area01.

  Next, the calculation unit 3B refers to the evaluation rule for each identified block and calculates an evaluation value of the listability of the blocks. At this time, the selection unit 31 of the calculation unit selects a calculation formula for usefulness for each block according to the use / type of the block information.

  Since there is no designation regarding the use / type of the block in the block information of block01, the selection unit 31 selects the usability function f (x) shown in Equation (1), and the calculation unit 3B determines the usefulness of block01. An evaluation value is calculated. The calculation unit 3B adds 100, which is the evaluation value of the usefulness of block01, and -5, which is the evaluation value of the line feed effect, and outputs 95 as the evaluation value of the listability in block01.

Next, in block 02, the designation relating to the use / type is “horizontal direction”, and therefore the selection unit 31 selects the usability evaluation function f2 (x) shown in FIG. The calculation unit calculates a display rate x = 20% from 1 which is the display amount of block 02 and 5 which is the information amount, and uses the function f ₂ (x) to calculate 64 as an evaluation value of the usefulness of block 02. Output. Note that since block 02 does not have a line feed position, the influence of useless line feed is not calculated. As a result, the evaluation value of the list property of block 02 is 64.

  Subsequently, the calculation unit 3B calculates the evaluation value of the listability of the area using the evaluation value of the listability for each block. Since block01 is 95 and block02 is 64, the list property of Area01 is 79.5 based on the sum average.

  As described above, according to the evaluation device 10B according to the second embodiment, in addition to the effects of the second embodiment, it is possible to calculate an evaluation value of usefulness according to the use / type for each block. It is possible to provide an evaluation value of the listability of areas and blocks including the evaluation value. That is, it is possible to provide an evaluation value of the listability of areas and blocks in consideration of display information in the blocks.

As a result, even if the operator of the evaluation apparatus 10B has no specialized knowledge or experience regarding usability, whether or not there is a problem or problem regarding the listability of the area and the block in consideration of the type and usage of the display information of the block Can be judged.
