[0048] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0049] <Outline of this embodiment> As shown in FIG. 1A, there are three Web pages W0 to W2, and their URLs are as follows: There are two web pages: W1 and W2. W0:http: / / aaa.com / home W1:http: / / aaa.com / home / A1 W2:http: / / aaa.com / home / A2

[0050] 1B, Web page W0 includes a link L1 to Web page W1 and a link L2 to Web page W2. However, link L1 is located at the top of Web page W0 in an easy-to-click position, whereas link L2 is located at the bottom of Web page W0 in a difficult-to-click position.

[0051] A conventional method for creating a site map showing the structure of a website containing these web pages W0-W2 is based on the hierarchical relationship (directory structure) of web pages W0-W2, as shown in Figure 2A. The site map in Figure 2A includes symbols S0-S2 corresponding to web pages W0-W2, respectively, with symbols S1 and S2 located below symbol S0. This site map shows that web page W0 is the base page, and web pages W1 and W2 are located one level below it.

[0052] However, in the site map of Figure 2A, the distance between symbol S0 and symbol S1 and the distance between symbol S0 and symbol S2 are displayed as equal, so the user's perceived distance (hereinafter referred to as "perceived distance") between web page W0 and web pages W1 and W2 is unclear.

[0053] In terms of the hierarchical structure, both web pages W1 and W2 are directly below web page W0, but according to the arrangement of links L1 and L2 on web page W0 as shown in Figure 1B, link L1 to web page W1 is easier to click, so the perceived distance from web page W0 to web page W1 should be shorter than the perceived distance from web page W0 to web page W2.

[0054] As such, a site map based on the hierarchical structure shown in Figure 2A does not reflect perceived distance. As a result, website creators who refer to such a site map may end up placing web pages that are closely related to each other in a perceived distance, or placing web pages that are loosely related to each other in a perceived distance, close to each other.

[0055] If such a website is constructed, users of the website may find it difficult to find a link to a web page that is highly related to the content (the perceived distance is long) when trying to move from the web page they are viewing to a web page that is highly related to the content. Also, by clicking on a link that is easy to find (the perceived distance is short), they may unintentionally move to a web page that is less related to the content.

[0056] Therefore, in this embodiment, a site map is generated taking the perceived distance into consideration, as shown in Fig. 2B. In the site map of Fig. 2B, symbols S0 to S2 are arranged so that the distance between symbol S0 and symbol S1 is shorter than the distance between symbol S0 and symbol S2. By generating such a site map, it can be seen that the perceived distance from web page W0 to web page W1 is shorter than the perceived distance from web page W0 to web page W2.

[0057] As described above, one of the objectives of this embodiment is to index the perceived distance when transitioning from one web page to another and to automatically generate a site map based on the index. The generation of a site map according to the perceived distance will be described in detail below.

[0058] <Configuration of the Sitemap Generator> 3 is a block diagram showing a schematic configuration of a site map generating device according to one embodiment. The site map generating device (sensory distance information generating device) is, for example, a personal computer or a smartphone, and includes an input interface 1, a setting unit 2, a sensible distance calculating unit 3, a site map generating unit 4 (sensory distance generating unit), an output control unit 5, and a display 6.

[0059] The input interface 1 is, for example, a touch panel, a mouse, a keyboard, a microphone, a camera, an eye tracking module, etc. A user uses the input interface 1 to perform an input operation on the site map generating device.

[0060] The setting unit 2 performs various settings by accepting input operations from a user via the input interface 1, for example.

[0061] As an example, the setting unit 2 sets a web page (hereinafter referred to as "reference web page") W0 that serves as a reference for measuring the perceived distance. The reference web page W0 can also be said to be the starting page of the measurement target. As a specific example, the setting unit 2 may accept input of a URL from the user, and set the web page identified by the URL as the reference web page W0. The reference web page W0 may be any web page, such as the top page (home page), terminal page, or intermediate page of a website.

[0062] The setting unit 2 also sets a web page (hereinafter referred to as a "target web page") that is the target of calculation of the perceived distance from the reference web page W0. There may be one or more target web pages.

[0063] As a specific example, the setting unit 2 may accept input of one or more URLs from the user, and set one or more web pages identified by the URLs as target web pages. As another specific example, the setting unit 2 may accept input of an upper limit number of clicks (number of operations) Nmax from the user, and set web pages that can be transitioned to from the reference web page W0 with Nmax or fewer clicks as target web pages. As yet another specific example, the setting unit 2 may set web pages in the same domain as the reference web page W0 as target web pages. As yet another specific example, the setting unit 2 may accept input of an arbitrary domain from the user, and set web pages that belong to this domain as target web pages. The setting unit 2 may set target web pages using any other method.

[0064] The setting unit 2 also sets criteria for determining a method for calculating the perceived distance and various conditions for displaying a site map. These settings may be based on a user operation.

[0065] The perceptual distance calculation unit 3 calculates the perceptual distance between web pages. As a specific example, the perceptual distance calculation unit 3 calculates the perceptual distance when transitioning from a reference web page W0 (first electronic medium, first screen) to a target web page (second electronic medium, second screen) by analyzing the reference web page W0. As a further specific example, the perceptual distance calculation unit 3 can calculate the perceptual distance based on a link (interface) for transitioning to the target web page, which is included in the reference web page W0. As a further specific example, the perceptual distance calculation unit 3 may calculate the perceptual distance based on the display position of the link on the reference web page.

[0066] A detailed example of the perceived distance calculation will be described later. The perceived distance may be calculated quantitatively as a numerical value, or may be classified into one of multiple stages such as long, medium, or short (this is also considered to be "calculated").

[0067] The site map generator 4 generates a site map (perceived distance information) showing the relationship between the reference web page W0 and the target web page based on the calculated perceived distance. This site map may include symbols corresponding to the reference web page W0 and / or the target web page, and the positions of the symbols and the distance between the symbols may correspond to the perceived distance. A detailed example of the site map will be described later.

[0068] The output control unit 5 displays a screen including the generated site map on the display 6. Alternatively, the output control unit 5 may print the site map on a paper medium or output it to an external recording medium.

[0069] On the display 6, a screen required for various settings is displayed in accordance with the control of the setting unit 2, and a site map is displayed in accordance with the control of the output control unit 5.

[0070] In addition, some or all of the setting unit 2, perceived distance calculation unit 3, site map generation unit 4 and output control unit 5 may be realized by the processor of the site map generation device executing a predetermined program, or may be implemented in hardware.

[0071] <Example of perceived distance calculation> There are various types of perceived distances. Examples include physical distance, operation distance, link path distance, cognitive distance, time distance, and user action distance. Furthermore, even for one type of perceived distance, there may be multiple calculation criteria (rules). The final perceived distance may be calculated by comprehensively considering multiple types of perceived distances and / or multiple perceived distances based on multiple criteria.

[0072] The type and standard of perceived distance to be considered may be predetermined, may be dynamically determined by the perceived distance calculation unit 3 by analyzing the reference web page W0 and / or the target web page, or may be set by the user via the setting unit 2.

[0073] <Physical distance> The perceived distance calculation unit 3 may calculate the perceived distance based on the physical location of the link to the target Web page on the reference Web page W0, and such a perceived distance is called a "physical distance."

[0074] As a specific example, assume that reference Web page W0 includes links L11 to L19 to multiple target Web pages W11 to W19, as shown in Figure 4A, and that these links L11 to L19 are arranged as shown in the figure. The physical distances between reference Web page W0 and target Web pages W11 to W19 are D11 to D19, respectively.

[0075] In this case, the perceived distance calculation unit 3 calculates the perceived distances D11 to D19 to the target Web pages W11 to W19 in consideration of the positional relationship (relative positional relationship) of the links L11 to L19. A predetermined standard (rule) is applied to the relationship between the positional relationship and the perceived distance.

[0076] As an example of the standard, the perceived distance may be determined in an inverted N-shape as shown in Fig. 4B. In this case, the perceived distances D11 to D19 between the reference Web page W0 and the target Web pages W11 to W19 have the following relationship: D11 <D12<D13<D16<D15<D14<D17<D18<D19 or D11 <D12<D13<D15<D17<D18<D19<D14<D16

[0077] As another example of the standard, the perceived distance may be set in a Z-shape as shown in Fig. 4C. In this case, the perceived distances D11 to D19 between the reference Web page W0 and the target Web pages W11 to W19 have the following relationship: D11 <D14<D17<D18<D15<D12<D13<D16<D19 or D11 <D14<D17<D15<D13<D16<D19<D12<D18

[0078] As another example of the standard, the perceived distance may be defined in an inverted Z-shape, as shown in Figure 4D. In this case, the perceived distances D11 to D19 between the reference Web page W0 and the target Web pages W11 to W19 have the following relationship: The inverted Z-shape is useful in languages ​​where characters are read from right to left. D17 <D14<D11<D12<D15<D18<D19<D16<D13 or D17 <D14<D11<D15<D19<D16<D13<D18<D12

[0079] As another example of the standard, the perceived distance may be set to an F-type as shown in Fig. 4E. In this case, the perceived distances D11 to D19 between the reference Web page W0 and the target Web pages W11 to W19 have the following relationship: D11 <D14<D17<D12<D15<D18<D13<D16<D19 or D11 <D14<D17<D12<D15<D13<D18<D16<D19

[0080] The inverted N-shape, Z-shape, inverted Z-shape, and F-shape described above are merely examples, and any one or more predetermined criteria (rules) for the relationship between the positional relationship and the perceived distance may be applied. The user may be able to set, via the setting unit 2, which criterion to apply to calculate the perceived distance. An example of such a method will be described later.

[0081] In general, the perceived distance calculation unit 3 may apply one or more criteria to calculate one or more physical distances, and may calculate the final physical distance by adding up the calculated physical distances with a predetermined weight. This weight may be determined in advance, or may be set by the user via the setting unit 2. When the physical distance based on a certain criterion k is xk and the weight applied to the criterion k is wk, the final physical distance l0 is calculated by the following formula.

[0082]

number

[0083] For example, let k = 1 to 2, where k = 1 indicates an inverted-N shape and k = 2 indicates a Z shape. Let weights w1 = 0.3 and w2 = 0.7. If the physical distance x1 when the inverted-N shape is applied is x1 = 3 and the physical distance x2 when the Z shape is applied is x2 = 5, then the final physical distance l0 is 4.4 (= 0.3 * 3 + 0.7 * 5).

[0084] By preparing various criteria (k=1, 2, ...) and setting the weight wk appropriately (setting the weight to 0 for criteria that are not taken into consideration), the perceived distance calculation unit 3 can calculate the desired physical distance. Note that in the above formula (1), the final physical distance l0 is calculated for each physical distance xk as follows: Although the relationship is linear, it may be nonlinear. This also applies to equation (2) and subsequent equations described later.

[0085] Furthermore, depending on the layout (configuration) of the reference Web page W0, the shape may be an inverted N, a Z, or an F. Therefore, the perceived distance calculation unit 3 may change the weight w taking into account the layout of the reference Web page W0.

[0086] For example, suppose the layout of the reference web page W0 is a single-column format as shown in Figure 5A. In this case, the physical distance between the target web page and the links placed in the header section is shorter than the physical distance between the target web page and the links placed in other sections, such as the navigation section. When multiple links are placed in the header section, the physical distance is determined in a Z-shape.

[0087] The physical distance between the target web page and the link in the navigation section is shorter than the link in the header section. When multiple links are placed in the navigation section, the physical distance is determined in a Z-shape.

[0088] The physical distances are determined in the following order. Figure 5B shows an example of the criteria when the reference web page layout is multi-column format, and Figure 5C shows an example of the criteria when the reference web page layout is grid format. Note that the criteria may also be set by the user; an example of how to do this will be described later.

[0089] The perceived distance calculation unit 3 may analyze which layout the reference Web page has, and apply a criterion (set a weight) according to the layout.

[0090] The relationship between the layout of the reference Web page W0 and the weight w may be determined in advance. Alternatively, the relationship between the layout and an appropriate weight w may be learned in advance using machine learning technology, and the setting unit 2 may identify an appropriate weight depending on the layout of the reference Web page W0. Alternatively, the perceived distance calculation unit 3 may set the weight w depending on the track record of the user's eye movement measured in advance for each reference Web page W0. Such track record may be acquired from an external device (not shown).

[0091] <Operating distance> The perceived distance calculation unit 3 may calculate the perceived distance by taking into consideration the user operation required to access the link to the target Web page on the reference Web page W0, and such a perceived distance is called the "operation distance."

[0092] The amount by which the user needs to move an operating device such as a mouse to access a link (hereinafter referred to as "device movement amount") can be applied as a criterion for calculating the operation distance. The relationship between the device movement amount and the operation distance may be proportional or non-linear. The user may be able to set the type of relationship via the setting unit 2.

[0093] An example of the device movement amount is the movement distance of a mouse pointer. In this case, the longer the distance from a predetermined position on the reference web page to the link to the target web page, the greater the perceived distance. The predetermined position may be, for example, a predetermined fixed position on the target web page (e.g., the upper left), or a position corresponding to the position of the link for transitioning to the target web page on the web page before transitioning to the target web page, or may be set by the user via the setting unit 2.

[0094] When calculating the amount of device movement using the movement distance of a mouse pointer, etc., The relationship between the distance and the mouse pointer movement may be proportional or non-linear. For example, when holding a smartphone in one hand and operating it with the thumb of the holding hand, if the value equivalent to the distance the mouse pointer moves is considered to be the distance the thumb moves to operate the touch panel, there are cases where the distance the thumb moves and the distance perceived are not proportional.

[0095] Specifically, if the distance is within d0, which is the distance that can be reached without changing the smartphone's position, then the amount of device movement and the operation distance may be proportional within that range (Figure 6A). On the other hand, if the distance is slightly out of reach without changing the smartphone's position (i.e., a distance greater than d0), even a small amount of device movement will cause a change of hand, and the relationship between the mouse pointer movement distance (device movement amount) and the perceived distance (operation distance) is likely to be significantly different from the proportional relationship. An arbitrary nonlinear correspondence between the movement distance and the perceived distance may be established to approximately address the above example.

[0096] Another example of the amount of device movement is the scroll distance. For example, as shown in Figure 6B, if the link L21 to the target Web page W21 is not displayed at the top of the reference Web page W0 (the state when the reference Web page W0 is displayed), and the link L21 appears by scrolling downward (specifically, by moving the scroll bar using a touch panel or a mouse, or by rotating the mouse wheel), the longer the amount of scrolling (the further down the link L22 is), the longer the perceived distance will be.

[0097] Note that scrolling includes horizontal scrolling in addition to vertical scrolling shown in FIG. 6B. The perceived distance calculation unit 3 may or may not calculate the operation distance by equally evaluating the scroll amount in vertical scrolling and the scroll amount in horizontal scrolling. For example, when the operation device is a mouse, vertical scrolling can generally be easily performed using the mouse wheel. Therefore, when the scroll amount in vertical scrolling and the scroll amount in horizontal scrolling are equal, it is desirable for the perceived distance calculation unit 3 to increase the operation distance of the latter.

[0098] Another criterion for calculating the operation distance may be the number of operations on the operation device (hereinafter referred to as the "number of device operations") required to transition to the target web page. The relationship between the number of device operations and the operation distance may be proportional or non-linear. The user may be able to set the type of relationship via the setting unit 2. Note that the operation distance when the operation is a click may also be called the click distance.

[0099] An example of the number of device operations is the number of key presses on a keyboard, which is an operation device, required to transition to a target web page.

[0100] 7, assume that reference Web page W0 includes objects (text, images, etc.) O1 and O2 and a link L22 to target Web page W22. When the tab key on the keyboard is pressed once while the reference Web page W0 is displayed, object O1 is selected, and when the tab key is pressed once again, object O2 is selected, and when the tab key is pressed once again, link L22 is selected. When the enter key is pressed with link L22 selected, the target Web page W22 is displayed.

[0101] In this case, the perceived distance calculation unit 3 calculates the operation distance based on the fact that the tab key needs to be pressed three times (the number of device operations is three).

[0102] Another example of the number of device operations is shown below. In the reference Web page W01 shown in FIG. 8A, when a button B21 labeled "Home Appliances" is selected (for example, by a user operation such as touching or clicking), a button B22 labeled "Television" appears. When this button is selected, a link L31 to a target Web page W31 related to "Televisions manufactured by Company A" and a link L32 to a target Web page W31 related to "Televisions manufactured by Company B" appear. Assume that a link L32 to the target Web page W32 appears. In other words, in order to expand the buttons B21 and B22 and display the links L31 and L32, two user operations are required after the reference Web page W01 is displayed.

[0103] On the other hand, in the reference web page W02 shown in FIG. 8B, the links L31 and L32 are displayed in advance. That is, in order to display the links L31 and L32, no further user operation is required after the reference web page W02 is displayed.

[0104] In this case, the perceived distance calculation unit 3 may make the operation distance D11 from the reference web page W01 to the target web page W31 longer than the operation distance D12 from the reference web page W02 to the target web page W31 (D12 < D11). This is because more user operations are required in the former case.

[0105] Note that the button B21 is arranged in the same way as the reference web page W01 shown in FIG. 8A. However, when the mouse cursor is placed over the button B21 (even without making a selection such as clicking), the button B22 appears. When the mouse cursor is placed over the button B22 (even without making a selection such as clicking), the links L31 and L32 appear. A reference web page W03 with such a configuration is also conceivable. In this case, regarding the operation distance D13 from the reference web page W03 to the target web page W31, the perceived distance calculation unit 3 may make D12 < D13 < D11. In order to display the link L31, in the reference web page W03, more user operations are required than in the reference web page W02 where no further user operation is required, but fewer user operations are required than in the reference web page W01 where selections (such as clicking) of the buttons B21 and B22 are required.

[0106] As another example of the number of device operations, the number of input characters required to transition from the reference web page W0 to the target web page can be cited.

[0107] In general, the perceived distance calculation unit 3 may calculate the operation distance by applying one or more criteria, and may sum them with a predetermined weight to obtain the final operation distance. This weight may be determined in advance or may be set by the user. When the operation distance based on a certain criterion k (k=0: device movement amount, k=1: number of device operations, etc.) is xk and the weight applied thereto is wk, the final operation distance l1 is calculated by the following formula.

[0108]

number

[0109] For example, let k = 1 to 2, where k = 1 indicates the device movement amount and k = 2 indicates the number of device operations. Also, let weights w1 = 0.3 and w2 = 0.7. If the operation distance x1 when the device movement amount is applied is 3 and the operation distance x2 when the number of device operations is applied is 5, the final operation distance l1 is 4.4 (= 0.3 * 3 + 0.7 * 5).

[0110] By preparing various criteria (k=1, 2, . . . ) and setting the weight wk appropriately (setting the weight to 0 for criteria that are not taken into consideration), the perceived distance calculation unit 3 can calculate the desired operation distance.

[0111] <Link path distance> The perceived distance calculation unit 3 may calculate the perceived distance based on the number of link selections (clicks, etc.) required to transition from the reference web page W0 to the target web page (e.g., the number of selections on the shortest path), and such perceived distance is called the "link path distance."

[0112] For example, if a link is selected from a reference web page to transition to another web page, and then a link on the other web page is selected to transition to a target web page, the link path distance is 2.

[0113] <Cognitive distance> The perceived distance calculation unit 3 may calculate the perceived distance based on how easily the link is perceived by the user, and such a perceived distance is called a "perceived distance."

[0114] The size, thickness, color, position, and font of the link (or the characters in the link, the same applies below) can be used as the criteria for calculating the perceived distance. Specifically, for example, the larger, thicker, or darker the link characters are, the shorter the perceived distance may be. The reference link color may be the color of the link itself, or the difference between the link and the background (brightness difference, hue difference, saturation difference, or any color space (e.g., L * a * b * It may also be a distance in space.

[0115] The relationship between perceived distance and color may be governed by a predetermined rule (a rule determined in advance or a rule set by the user via the setting unit 2). For example, the perceived distance to a target web page associated with a link whose text color is red may be short, and the perceived distance to a target web page associated with a link whose text color is blue may be long. The same applies to fonts.

[0116] In general, the perceived distance calculation unit 3 may calculate the perception distance by applying one or more criteria and summing them with a predetermined weight to obtain the final perception distance. This weight may be determined in advance or may be set by the user. Specifically, when the perception distance based on a certain criterion k (k=0: size, k=1: thickness, k=2: color, k=3: position, k=4: character font, etc.) is xk and the weight applied thereto is wk, the final perception distance l2 is calculated by the following formula:

[0117]

number

[0118] The cognitive distance may differ depending on the user's attributes (for example, age, gender, and type of illness or injury). Therefore, the weight w may be changed depending on the target user.

[0119] <Time distance> The perceived distance calculation unit 3 may calculate the perceived distance by taking into consideration the time required to display the target web page, and such a perceived distance is called a "time distance."

[0120] The time until a link becomes accessible can be used as a criterion for calculating the time distance. For example, if a link appears (or becomes selectable) after an animated video finishes displaying on the reference web page W0, the perceived distance calculation unit 3 may increase the time distance to the target web page associated with that link. Also, the perceived distance calculation unit 3 may increase the time distance the longer it takes the reference web page to load. Such times can be determined by analyzing the reference web page W0.

[0121] As another criterion for calculating the time distance, the perceived distance may be calculated by taking into consideration the time from when the user performs an operation on the operating device to transition from the reference web page W0 to the target web page (for example, clicking a mouse or touching a touch panel) to when the target web page is displayed (appears). This time is the time from when the web browser loads the target web page to when it displays it, and can be measured by the web browser. If necessary, the perceived distance calculation unit 3 may acquire information about the time from when the web browser or the like displays the target web page.

[0122] <User behavior distance> The perceived distance calculation unit 3 may calculate the perceived distance by taking into consideration the history of transitions from the reference Web page W0 to the target Web page (user behavior), and such a perceived distance is called a "user behavior distance."

[0123] For example, if many users transition from reference web page W0 to target web page W1, but few users transition from reference web page W0 to target web page W2, the perceived distance from reference web page W0 to target web page W1 will be shorter than the perceived distance from reference web page W0 to target web page W2.

[0124] The transition record of which web page was used to transition to which other web page can be easily grasped using existing technology (such as an access analysis tool). If necessary, the perceived distance calculation unit 3 can acquire information about the transition record from the access analysis tool or the like.

[0125] <Other perceived distances> The transition from the reference web page W0 to the target web page is not necessarily limited to the selection of a link. For example, the transition from the reference web page W0 to the target web page may be possible by voice, gesture, gaze, etc. In this case, the perceived distance calculation unit 3 may calculate the perceived distance taking these transitions into consideration. As an example, if the transition by one click is set to a perceived distance of 1, the transition by voice may be set to a perceived distance of 0.9.

[0126] <Device-dependent perceived distance> The perceived distance calculation unit 3 may calculate the perceived distance based on the target device on which the reference Web page W0 is displayed. For example, as shown in Fig. 9, the reference Web page W0 includes a link L11 to a target Web page W11 located in the upper left and a link L12 to a target Web page W12 located in the lower right.

[0127] If the target device is a personal computer and the reference web page is displayed on the personal computer's display or an external display connected to the personal computer, it is considered that a user is more likely to click on the link L11 located in the upper left corner. Therefore, in this case, the perceived distance calculation unit 3 makes the perceived distance from the reference web page W0 to the target web page W11 shorter than the perceived distance from the reference web page W0 to the target web page W12.

[0128] On the other hand, if the target device is a smartphone and the reference web page W0 is displayed on a touch panel display of the smartphone, many users will Since the user holds the phone in his right hand, it is considered that link L12 is easier to click. Therefore, in this case, the perceived distance calculation unit 3 makes the perceived distance from the reference web page W0 to the target web page W11 longer than the perceived distance from the reference web page W0 to the target web page W12.

[0129] Furthermore, the display area and display size differ depending on the device on which the reference web page W0 is displayed. For example, a relatively large device such as a personal computer displays a large area of ​​the reference web page. On the other hand, a relatively small device such as a smartphone displays only a small area of ​​the reference web page. Therefore, the perceived distance calculation unit 3 may calculate the perceived distance taking into account the area on which the reference web page W0 is displayed and / or the size of the device on which it is displayed.

[0130] <Calculating perceived distance> As described above, the perceived distance calculation unit 3 can calculate various types of perceived distances based on various criteria. The perceived distance calculation unit 3 may calculate one or more types of perceived distances described above based on one or more criteria, and may calculate the final perceived distance by comprehensively adding up these calculated values.

[0131] The concept of calculating perceived distance is illustrated in FIG. The final perceived distance L (first perceived distance) can be calculated by adding the perceived distances di (second and third perceived distances) for one or more target devices i with a predetermined weight wi. That is, the final perceived distance L is calculated using the following formula. As an example, i=0: the target device is a PC, i=1: the target device is a smartphone, etc.

[0132]

number

[0133] The perceived distance di for the target device i can be calculated by adding the perceived distances lij (second and third perceived distances) of type j with a predetermined weight wij. That is, the perceived distance di for the target device i is calculated by the following formula. As an example, j=0: physical distance, j=1: operation distance, etc.

[0134]

number

[0135] The perceived distance lij of type j for target device i is the perceived distance when criterion k is applied. The distance xijk (second and third perceived distances) can be calculated by adding them together with a predetermined weight wijk. That is, the perceived distance lij of type j for target device i is calculated using the following formula. As an example, when j=0 (physical distance), k=0 is an inverted N-shape, k=1 is a Z-shape, etc.

[0136]

number

[0137] In the general formulas (4) to (6) above, by appropriately setting the weight w, it is possible to adjust what type of perceived distance and what criteria are applied to calculate the perceived distance. The weight w may be determined in advance, or may be set by the user via the setting unit 2. Alternatively, the perceived distance setting unit 2 may dynamically set the weight w based on the reference Web page W0.

[0138] In this embodiment, the directory distance between the reference web page W0 and the target web page (how many levels in the directory structure they are separated from) is not itself used as the perceived distance. However, the directory distance can be used as one type and combined with other types of perceived distance to calculate the perceived distance. In this case, if the reference web page W0 and the target web page are on the same level, the directory distance may be set to 0 or 2, or may be user-configurable.

[0139] In this embodiment, the semantic distance between the reference web page W0 and the target web page (how similar the contents of the two web pages are) itself is not taken as the perceived distance. However, the semantic distance can be used as one type and combined with other types of perceived distance to calculate the perceived distance. The semantic distance is calculated by the perceived distance calculation unit 3 using a known method. As an example, the perceived distance setting unit 2 may calculate the semantic distance by performing natural language processing. Specifically, the semantic distance may be calculated based on the distance between a multidimensional feature vector based on the contents of the reference web page and a multidimensional feature vector based on the contents of the target web page (see Japanese Patent No. 6680956).

[0140] <Processing Operation of Sitemap Generator> FIG. 11A is a flowchart showing an example of the processing operation of the site map generating device.

[0141] The setting unit 2 accepts input of a reference web page from the user, thereby setting the reference web page (step S1). The setting unit 2 also accepts input of a target web page from the user, thereby setting the target web page (step S2). The setting unit 2 also accepts input of a perceived distance calculation method from the user, thereby setting the perceived distance calculation method (step S3). The order of steps S1 to S3 may be reversed as appropriate.

[0142] For these settings, the setting unit 2 causes the display 6 to display a screen such as the one shown in FIG. 12A.

[0143] The user inputs the URL of the web page they want to use as the reference web page into the reference web page URL input field A1, and the setting unit 2 sets the reference web page accordingly.

[0144] The user checks the checkbox associated with the web page that the user wants to set as the target web page, and the setting unit 2 sets the target web page accordingly.

[0145] If none of the checkboxes are checked, the setting unit 2 sets only web pages in lower-level directories within the same site (i.e., having the same domain) as the reference web page as target web pages. If checkbox B1 is checked, the setting unit 2 also sets web pages in other directories within the same site as the reference web page as target web pages. If checkbox B2 is checked, the setting unit 2 also sets web pages in subdomains of the reference web page as target web pages. If checkbox B3 is checked, the setting unit 2 also sets web pages in other domains than the reference web page as target web pages. If checkbox B4 is checked, the setting unit 2 also sets advertising web pages as target web pages.

[0146] The user checks the checkboxes associated with the items (types and standards) that the user wants to consider when calculating the perceived distance. In response to this, the setting unit 2 sets the perceived distance calculation method. Setting the perceived distance calculation method is, for example, setting the weights in the above equations (4) to (6).

[0147] 11A, based on the settings made in steps S1 to S3, the perceived distance calculation unit 3 calculates the perceived distance from the reference web page to the target web page (step S4). Then, based on the calculated perceived distance, the site map generation unit 4 generates a site map, and the output control unit 5 displays the site map on the display 6 (step S5).

[0148] If the user determines that there is a problem with the displayed site map (for example, that it is significantly different from intuition), the perceived distance calculation method may be reset (step S3) and the site map may be generated again.

[0149] In the process of Fig. 11A, the perceived distance is calculated for all target web pages set in step S2 of Fig. 11A and Fig. 12A. However, if web pages that are barely recognized even if they are included in the target web pages are included in the perceived distance calculation, the perceived distance may become meaningless.

[0150] Therefore, before calculating the perceived distance, target web pages that are less meaningful may be excluded and the perceived distance may be calculated. As a specific example of such a method, a standard perceived distance (e.g., cognitive distance) may be set, and the perceived distance may be calculated only for target web pages whose perceived distance satisfies a predetermined condition (e.g., shorter than the standard value). This will be specifically described below.

[0151] Fig. 11B is a flowchart showing another example of the processing operation of the site map generating device. Fig. 12B is a diagram showing another example of a screen displayed on the display by the setting unit 2. In Fig. 11B and Fig. 12B, common reference numerals are used to designate processes common to Fig. 11A and Fig. 12A, respectively.

[0152] The setting unit 2 sets the reference web page, the target web page, and the perceptual distance calculation method (steps S1, S2', S3) by using the screen shown in Fig. 12B, etc. Furthermore, the setting unit 2 sets the reference perceptual distance (fourth perceptual distance) and the reference value (predetermined condition) (step S11).

[0153] The target web page set in step S2' is a temporary one (third electronic medium). For example, in FIG. 12B, a tentative target Web page is set depending on whether or not each of the check boxes B1 to B4 is checked (this is the same as step S2 in FIG. 11A).

[0154] If the user wishes to exclude a perceived distance that is of little significance, the user checks the check box C1 in FIG. 12B. The user also sets a reference perceived distance (reference perceived distance) in the reference perceived distance setting field C2, and sets a threshold value in the reference value setting field C3. The reference perceived distance may be any of the above-mentioned perceived distances, for example, the cognitive distance. In this way, the setting unit 2 sets the reference perceived distance and the reference value. Note that the reference perceived distance and / or the reference value may not be set by the user, but may be determined in advance.

[0155] Next, the sensory distance calculation unit 3 calculates the reference sensory distance from the reference web page to the tentative target web page (step S12). Then, the setting unit 2 sets, as the target web page, the tentative target web page whose reference sensory distance is shorter than a reference value (step S2). In other words, the setting unit 2 excludes, from the target web page, the tentative target web page whose reference sensory distance is equal to or greater than the reference value.

[0156] Then, the sensible distance calculation unit 3 calculates the sensible distance for the target web page set in step S2 (step S4). In other words, in step S4, the sensible distance is not calculated for any tentative target web page whose reference sensible distance is equal to or greater than the reference value.

[0157] In this way, links to web pages whose standard perceived distance is equal to or greater than the standard value can be regarded as invalid links and excluded from the target web pages. This allows for a more realistic perceived distance to be calculated. In addition, the number of target web pages for which the perceived distance is calculated can be reduced, thereby reducing the processing load of the perceived distance calculation unit 3.

[0158] <Example of a site map> The site map generator 4 generates a site map (perceived distance information) showing the relationship between the reference web page W0 and the target web page based on the perceived distance between them. The generated site map is displayed on the display 6 or printed out. This visualizes the relationship between the reference web page W0 and the target web page. By visualizing it on the display 6, the relationship between the reference web page W0 and the target web page can be intuitively grasped in a short time. This reduces the time required to display the site map on the display 6, and reduces the power consumption of the display 6.

[0159] As an example, the displayed or printed site map may include some or all of the nodes (symbols) corresponding to the reference web page W0, the nodes (symbols) corresponding to the target web pages, and the edges (paths) connecting the nodes.

[0160] The relationship between the reference web page and the target web page visualized in the site map may be one or more of the final perceived distance (the perceived distance L in equation (4) above), the perceived distance on a specific target device i (the distance di in equation (5) above), the perceived distance on a specific target device i and a specific type j (the distance lij in equation (6) above), and the perceived distance on a specific target device i, a specific type j, and a specific reference k (xijk in equation (6) above). If there are two or more, one of them may be the semantic distance or directory distance between the reference web page and the target web page.

[0161] Such a relationship can be expressed by elements such as the display position of the node (x coordinate and / or y coordinate, and also z coordinate in the case of a three-dimensional display) and the display mode. For example, the size of the node, the thickness of the edge, the color of the node and / or edge (brightness, saturation, transparency, hue, etc.), the pattern (such as displaying nodes corresponding to target web pages that are within a specified perceived distance from the reference web page with the same pattern), and animation display (such as flashing at a speed according to the perceived distance, zooming in and out, etc.).

[0162] It may be predetermined which relationship is represented by which element, or it may be settable by the user via the setting unit 2.

[0163] FIG. 13A and FIG. 13B are schematic diagrams showing an example of a site map. In both figures, the horizontal axis (x-axis) is the perceived distance from the reference web page W0 on the smartphone, and the vertical axis (y-axis) is the perceived distance from the reference web page W0 on the personal computer. That is, it is an example in which information on the perceived distance on the smartphone and the perceived distance on the personal computer is represented by elements such as the display positions (x-coordinate and y-coordinate) of the nodes.

[0164] The arrangement position of the node N1 (corresponding to the target web page Wt1) in FIG. 13A means that the perceived distance from the reference web page W0 to the target web page Wt1 on the smartphone is x1, and the perceived distance on the personal computer is y1. Similarly, the arrangement position of the node N2 (corresponding to the target web page Wt2) means that the perceived distance from the reference web page W0 to the target web page Wt2 on the smartphone is x2, and the perceived distance on the personal computer is y2.

[0165] According to FIG. 13A, since x1 < x2 and y1 < y2, it can be seen that the perceived distances of the target web pages Wt1 and Wt2 with respect to the reference web page W0 do not depend much on the device (whether it is a smartphone or a personal computer).

[0166] The arrangement position of the node N11 (corresponding to the target web page Wt11) in FIG. 13B means that the perceived distance from the reference web page W0 to the target web page Wt11 on the smartphone is x11, and the perceived distance on the personal computer is y11. Similarly, the arrangement position of the node N12 (corresponding to the target web page Wt12) means that the perceived distance from the reference web page W0 to the target web page Wt12 on the smartphone is x12, and the perceived distance on the personal computer is y12.

[0167] According to Figure 13B, x11<x12であるがy11> y12, it can be seen that the perceived distance of the target web pages Wt11 and Wt12 relative to the reference web page W0 differs depending on the device (whether it is a smartphone or a PC).

[0168] In this way, it is possible to verify whether there is a difference in perceived distance depending on the device. The closer x and y are to a proportional relationship, the smaller the difference between devices.

[0169] 14A and 14B are schematic diagrams showing other examples of site maps. In both cases, the horizontal axis (x-axis) represents the link path distance to the reference Web page W0, and the hue represents the semantic distance to the reference Web page W0. For convenience, the dotted patterns (nodes N1, N2, N11, and N13) in FIGS. 14A and 14B represent a certain hue and have a similar meaning to the reference Web page W0. The diagonal lines (nodes N3 and N12) represent a different hue and have a different meaning from the reference Web page W0.

[0170] 14A, nodes N1 and N2 corresponding to target web pages Wt1 and Wt2, which have similar meanings to reference web page W0, are arranged close to each other at small values ​​of x. On the other hand, node N3 corresponding to target web page Wt3, which has a different meaning from reference web page W0, is arranged far from nodes N1 and N2 at large values ​​of x. .

[0171] According to Figure 14A, for the reference web page W0, the target web pages Wt1 and Wt2, which have a similar meaning to the reference web page W0, both have short link path distances, while the target web page Wt3, which has a different meaning, has a long link path distance.

[0172] 14B, node N11 corresponding to target web page Wt11, which has a similar meaning to reference web page W0, is placed where the value of x is small, while node N13 corresponding to target web page Wt12, which also has a similar meaning to reference web page W0, is placed where the value of x is large. Also, node N12 corresponding to target web page Wt12, which has a different meaning from reference web page W0, is placed close to node N11 where the value of x is small.

[0173] 14B, it can be seen that, in the reference Web page W0, the target Web page Wt13 has a longer link path distance despite having a similar meaning to the reference Web page W0, and that, in the reference Web page W0, the target Web page Wt12 has a shorter link path distance despite having a different meaning from the reference Web page W0.

[0174] In this way, it is possible to verify whether a target Web page that has a similar meaning to the reference Web page W0 has a shorter link path distance.

[0175] 14A and 14B, the horizontal axis may represent the recognition distance, which makes it possible to verify whether a target Web page that has a similar meaning to the reference Web page W0 is more easily recognized.

[0176] In this way, the perceptual distance calculation unit 3 calculates the perceptual distance and the semantic distance, thereby making it possible to grasp the relationship between them. The output control unit 5 may issue an alert if the perceptual distance and the semantic distance have a predetermined relationship. The predetermined relationship refers to, for example, when the semantic distance between the reference web page and the target web page is equal to or less than a predetermined value (similar in meaning) but the perceptual distance is equal to or greater than a predetermined value (distant in meaning), or conversely, when the semantic distance is equal to or greater than a predetermined value (close in meaning) but the semantic distance is equal to or greater than a predetermined value (different in meaning).

[0177] FIG. 15 is a schematic diagram showing another example of a site map. The horizontal axis represents the physical distance from the reference Web page W0, and the vertical axis represents the operating distance from the reference Web page W0. The size of the node represents the cognitive distance, with the larger the node, the shorter the cognitive distance. In this way, different types of perceived distances may be represented by different elements in the site map. Alternatively, the same type of perceived distance may be calculated multiple times with different weights relative to the reference, and these may be represented by multiple elements in the site map.

[0178] 16 is a schematic diagram showing another example of a site map. This site map includes node N0 corresponding to reference Web page W0, and nodes N11 to N13 and N21 corresponding to target Web pages Wt11 to Wt13 and Wt21, respectively.

[0179] The vertical axis (y-axis) of this site map corresponds to the click distance required to reach each of the target web pages from the reference web page W0. For example, it takes one click to reach the target web pages Wt11 to Wt13 from the reference web page W0, and two clicks to reach the target web page Wt21 from the reference web page W0.

[0180] The horizontal axis (x-axis) corresponds to the perceived distance from the reference Web page W0 to each of the target Web pages. For example, the relationship between the perceived distances L11 to L13 between the reference Web page W0 and each of the target Web pages Wt11 to Wt13 is L11. <L12<L13である。

[0181] The length of an edge path between two nodes corresponds to the perceived distance between the web pages corresponding to those nodes. For example, edge E11 between node N0 and node N11 corresponds to the perceived distance L11 between reference web page W0 and target web page Wt11. Note that "corresponding" does not necessarily mean that the edge length and the perceived distance correspond one-to-one (e.g., are proportional), but may be such that the relationship between multiple perceived distances can be understood.

[0182] In the site map described above, the user may be able to set various parameters. For example, in a node, the URL of the corresponding web page, the title of the HTML file, It may be possible to set whether to display various tags such as meta keywords, meta description, h1, backlink anchor, and backlink alt. It may also be possible to display what meaning each page has and to what extent (see Japanese Patent No. 6680956). Also, the color and style of the edges may be set by the user. The edges may be displayed in a shape that corresponds to whether the link between the web pages is one-way or two-way.

[0183] FIG. 17 is a schematic diagram showing another example of a site map. As shown in the figure, the site map may be displayed in table (list) format. In this figure, target web pages Wt1 to Wt3 are displayed as nodes, and the final perceived distance, physical distance, and operation distance are associated with each other. When output in table format, it is desirable that the output control unit 5 be able to sort the target web pages in order of perceived distance.

[0184] 18A and 18B are schematic diagrams showing another example of a site map. As shown in FIG. 18A, the output control unit 5 displays a directory structure of multiple web pages. Each node Ni corresponds to each web page Wi. As explained with reference to FIG. 2A, a site map based on a directory structure does not indicate perceived distance.

[0185] The user can select any node (i.e., web page). As a result, the setting unit 2 sets the selected web page as the reference web page and sets the other web pages as target web pages. Here, it is assumed that node N32 (web page W32) is selected.

[0186] Then, the site map generating unit 4 generates edges to other nodes starting from node N32 as shown in Fig. 18B. The display style (for example, thickness) of these edges corresponds to the perceived distance.

[0187] For example, the edge from node N32 to node N41 is thick. This indicates that the perceived distance between web page W32 and web page W41, which is one level below it, is short. On the other hand, the edge from node N32 to node N43 is thin. This indicates that although web page W43 is only one level below web page W32, the perceived distance between web page W32 and it is long.

[0188] The site map generating unit 4 may generate edges between the node corresponding to the reference web page and the nodes corresponding to all other target web pages, or may generate edges only between the nodes corresponding to target web pages whose perceived distance is equal to or less than a threshold value. A predetermined number of edges may be generated in ascending order of length. The threshold value and the predetermined number may be determined in advance or may be set by the user.

[0189] 19A to 19C are diagrams for explaining an example of the processing operation of the site map generating device, and may be combined with any of the above-described embodiments as long as no contradiction occurs.

[0190] As shown in FIG. 19A, the output control unit 5 displays information indicating a plurality of web pages on the display 6. As an example, the information indicating the web pages may be the ID and URL of the web page. The display format may be a table format. In FIG. 19A, the plurality of web pages includes a web page whose URL includes "abc.com" (web page Wa). and the web page one layer below that are shown as examples, but there are no particular limitations, and the output control unit 5 may display information on any web page.

[0191] In this state, the table shown in FIG. 19A has a column for displaying the perceived distance, but since it has not been determined which web page will be the reference web page, the perceived distance is not displayed.

[0192] The user selects a web page to be set as the reference web page via the input interface 1. For example, assume that web page Wb is selected as shown in FIG. 19B. In this case, the setting unit 2 sets the selected web page Wb as the reference web page and sets the other web pages Wa, Wc, and Wd as target web pages. Note that the setting unit 2 may set only some of the other web pages Wa, Wc, and Wd (for example, those with a directory distance equal to or less than a predetermined value) as target web pages.

[0193] Then, the perceived distance calculation unit 3 calculates the perceived distance between the reference web page Wb and the other target web pages Wa, Wc, and Wd. Furthermore, the output control unit 5 displays the calculated perceived distance in association with each target web page. Specifically, the output control unit 5 displays the calculated perceived distance in the column displaying the perceived distance in the table shown in FIG. 19B. In FIG. 19B, for example, the perceived distance between the reference web page Wb and the target web page Wa is "2." Note that the perceived distance of the reference web page Wb may be "0" as shown, or may be a "-" (hyphen), or may not be displayed at all. In any case, it is desirable to be able to identify which web page is the reference web page.

[0194] Here, when the user issues a predetermined sort instruction (for example, by selecting the column or title section that displays the perceived distance), the output control unit 5 sorts the target Web pages Wa, Wc, and Wd in order of perceived distance, as shown in Fig. 19C. The sorting order may be either in ascending or descending order of perceived distance.

[0195] 20A and 20B are diagrams for explaining another example of the processing operation of the site map generating device, and may be combined with any of the above-described embodiments as long as no contradiction occurs.

[0196] 20A, similar to Fig. 19A, the output control unit 5 displays information indicating a plurality of web pages on the display 6. In this state, the table shown in Fig. 20A has columns for displaying the perceptual distance and the semantic distance, but because it has not been determined which web page will be the reference web page, the perceptual distance and the semantic distance are not displayed.

[0197] The user selects a web page to be set as the reference web page via the input interface 1. For example, as shown in FIG. 20B, assume that web page Wb is selected. In this case, the setting unit 2 sets the selected web page Wb as the reference web page, and sets the other web pages Wa, Wc, and Wd as target web pages. Note that the setting unit 2 does not set the other Web pages Wa, Wc, and Wd as target web pages. b Only some of the pages Wa, Wc, and Wd (for example, pages with a directory distance equal to or less than a predetermined value) may be set as target Web pages.

[0198] The perceptual distance calculation unit 3 then calculates the perceptual distance and semantic distance between the reference web page Wb and the other target web pages Wa, Wc, and Wd. Furthermore, the output control unit 5 displays the calculated perceptual distance and semantic distance in association with each target web page. Specifically, the output control unit 5 displays the calculated perceptual distance and semantic distance in the perceptual distance display field and the semantic distance display field in the table shown in FIG. 20B. In FIG. 20B, for example, the perceptual distance between the reference web page Wb and the target web page Wa is "2," and the semantic distance is "3." The semantic distance of the reference web page Wb may be "0" as shown, or may be a "-" (hyphen), or may not be displayed at all. In any case, it is desirable to be able to identify which web page is the reference web page.

[0199] Furthermore, the output control unit 5 may display the gap between the perceptual distance and the semantic distance in association with each target Web page. Any method for calculating the gap may be used, but one example is the absolute value of the difference between the perceptual distance and the semantic distance. Here, as described with reference to Figures 19A to 19C, the Web pages may be rearranged based on the perceptual distance (or semantic distance).

[0200] The output control unit 5 may also issue an alert depending on the gap (in other words, depending on the perceptual distance and semantic distance). For example, if there is a target web page whose gap is equal to or greater than a threshold, an alert specifying the target web page may be issued. In FIG. 20B, if the threshold is 3, an alert is issued because the gap for the target web page Wc is equal to or greater than the threshold. This alert indicates an undesirable state in which the perceptual distance is long despite the semantic distance being short (i.e., the perceptual distance should be short), or the perceptual distance is short despite the semantic distance being long (i.e., the perceptual distance should be long).

[0201] In the above example, if the gap between perceived distance and semantic distance is not the absolute value of the difference but the difference, it can take a negative value. In that case, the criterion for issuing an alert can be when the gap is within or outside a certain range, rather than being judged by a single threshold.

[0202] <User setting of criteria for calculating perceived distance> The user may be able to set a standard for the above-mentioned operation distance. A specific example of such a method will be described below.

[0203] The setting unit 2 causes the output control unit 5 to display an icon A1 at a certain position on the display 5 (see FIG. 21A). Then, the user selects the displayed icon A1 as quickly as possible via the input interface 1. That is, the setting unit 2 accepts the selection of the displayed icon A1 from the user. The setting unit 2 keeps track of the time from when the icon A1 is displayed on the display 5 until it is selected by the user.

[0204] Next, the setting unit 2 displays the icon A2 at another position on the display 5 (see FIG. 21B). Then, the user selects the displayed icon A2 as quickly as possible via the input interface 1. That is, the setting unit 2 accepts the selection of the displayed icon A2 from the user. The setting unit 2 grasps the time from when the icon A2 is displayed on the display 5 until it is selected by the user (hereinafter referred to as the "selection time").

[0205] The above processing operation is performed at each position on the display 5. That is, the setting unit 2 sequentially displays icons at each position on the display. Then, the setting unit 2 accepts the selection of the displayed icon from the user. Note that the icons are displayed at all positions on the display 5. The icon may be displayed in only some of the locations, or may be displayed multiple times in one location.

[0206] When the display of the icons at each position on the display 5 and the user's selection are completed, the setting unit 2 may display the relationship between the icon position and the selection time on the display 2. As an example, as shown in Fig. 22, a screen including the icons arranged at each position and the selection time when the icons were displayed at that position is displayed.

[0207] Then, the setting unit 2 generates a criterion for calculating the operation distance based on the selection time. As a specific example, a criterion is generated such that the operation distance becomes longer for a target Web page associated with a link displayed at a position corresponding to an icon in the reference Web page W0 that has been selected for a longer time. For example, the criterion is set so that the perceived distance for the target Web page associated with the link L3 (see FIG. 23) displayed at a position corresponding to the icon A3 in FIG. 22 in the reference Web page W0 is "1," and the perceived distance for the target Web page associated with the link L4 (see FIG. 23) displayed at a position corresponding to the icon A4 is "5."

[0208] The setting unit 2 may accept in advance from the user a device that displays the icons shown in Fig. 21A and Fig. 21B. For example, in the case of a smartphone, the setting unit 2 generates criteria for the smartphone.

[0209] The setting unit 2 may also receive in advance from the user whether the selection operation will be performed with the left hand or the right hand. For example, when the selection operation is performed with the left hand, the setting unit 2 generates a reference for the left hand. Then, the perceived distance calculation unit 3 calculates the operation distance assuming that the selection operation will be performed with the left hand.

[0210] Furthermore, the setting unit 2 may measure a selection success rate (or failure rate) in addition to the selection time. For example, if the icon A1 is displayed at the position shown in FIG. 21A 10 times, and the number of times that the icon A1 is correctly selected is 8, the number of times that a location different from the icon A1 is selected is 1, and the number of times that the selection operation cannot be performed within the predetermined time limit is 1, the success rate is 80%. The setting unit 2 may then generate a standard such that the higher the success rate, the shorter the operation distance. The success rate (or failure rate) may be displayed on the screen of FIG. 22.

[0211] Furthermore, the setting unit 2 may measure the deviation distance when the selection fails. The deviation distance is the distance between the position of the displayed icon and the position selected by the user. The setting unit 2 may then generate a standard such that the longer the deviation distance, the longer the operation distance. Note that the deviation distance when the selection fails may be displayed on the screen of FIG. 22.

[0212] Alternatively, the setting unit 2 may simultaneously display multiple icons A5 and A6 at multiple positions as shown in FIG. 21C. The user then selects icons A5 and A6 via the input interface 1 as quickly as possible in the order that the user finds most convenient. The setting unit 2 may also generate a criterion taking into consideration the selection order. The setting unit 2 may also generate a criterion taking into consideration the selection time difference between an icon selected earlier and an icon selected later. For example, the longer the selection time difference, the greater the difference in operation distance between the position of the icon selected earlier and the position of the icon selected later.

[0213] Additionally, the setting unit 2 may accept settings for the display mode of the icon to be displayed (shape, size, color, border color, border thickness, etc.) from the user. This allows the generation of criteria according to the display mode of the link.

[0214] The setting unit 2 also sets the display positions of the icons and / or the spacing between the icons. The more display positions are set and the smaller the intervals are set, the more accurate the reference can be generated. On the other hand, the fewer display positions are set and the larger the intervals are set, the shorter the time it takes to generate the reference.

[0215] The setting unit 2 may also receive settings from the user, such as the icon display speed, display time, number of icons to be displayed simultaneously, and the order in which the icons are to be displayed. Additionally, the setting unit 2 may receive any setting from the user and set the criteria in consideration of the received information.

[0216] Next, an example of setting a reference for calculating a physical distance will be shown. Web page layout patterns include the single-column format (Figure 24A), the multi-column format (Figure 25), and the grid format (Figure 26). For example, in the single-column format, the display area is divided into multiple areas, such as a header section, a navigation section, a content section, and a footer section.

[0217] The setting unit 2 displays a certain layout pattern on the display 5 via the output control unit 5 (see FIG. 27, showing a single-column format as an example). This screen has, for example, order setting fields D1, D2, etc. for each area, allowing the user to arbitrarily set the order of physical distance for each area. For example, if the user wants to set the physical distance in the order of shortest to shortest for the header section, navigation section, content section (left), content section (center), content section (right), content section (bottom), and footer section, the order is set as shown in FIG. 27.

[0218] In this way, the setting unit 2 receives information setting from the user regarding the perceived distance (order) for each area. Then, the setting unit 2 generates a standard for calculating the physical distance based on the set information. For example, according to the example in FIG. 27, if the reference web page has a single-column format, the physical distance to the target web page corresponding to the link located in the header section will be shorter than the physical distance to the target web page corresponding to the link located in the navigation section.

[0219] Furthermore, multiple links may be placed in each area of ​​the layout pattern, so the setting unit 2 may generate a reference within the area.

[0220] As a specific example, a layout pattern such as that shown in Figure 28 (illustrating a single column format) is displayed on the display 5. On this screen, for example, multiple icons E1, E2, etc. are arranged in each area, and the user can arbitrarily set the order of physical distances for each icon in the area.

[0221] For example, if the user wants the links in the header section to be Z-shaped and the links in the navigation section to be in an inverted N-shape, the order is set as shown in FIG.

[0222] In this way, the setting unit 2 displays icons at various positions on the display and receives information from the user regarding the perceived distance (order) for each icon. The setting unit 2 then generates a standard for calculating the physical distance based on the set information. For example, in the example of FIG. 28, if the reference web page has a single-column format, the physical distance is calculated in a Z-shape for multiple links located in the header section, and the physical distance is calculated in an inverted N-shape for multiple links located in the navigation section.

[0223] Note that when a plurality of icons are displayed as in FIG. 28 and a physical distance setting is received from the user, it is not necessarily required to divide the display area into a plurality of areas.

[0224] As described above, according to this embodiment, information indicating the perceived distance between Web pages can be generated, which is useful for site creators.

[0225] In the above embodiment, the perceived distance between web pages has been mainly discussed, but the present invention can be applied to other things besides web pages. For example, the present invention can also be applied to the perceived distance between any screens displayed on a display. As a more specific example, in electronic guidance such as an app, game, or ATM (automated teller machine) monitor that transitions between multiple screens, the perceived distance from a reference screen to a target screen may be calculated to generate perceived distance information. Furthermore, the present invention is not limited to web pages or screens, and can also be applied to the perceived distance between any electronic media.

[0226] Furthermore, in the above embodiment, transitions caused by link selection have been mainly discussed, but the present invention can be applied to transitions caused by any user event, such as voice, gesture, or gaze.

[0227] The programs mentioned in this specification may be distributed by being non-temporarily recorded on a computer-readable recording medium, or may be distributed via a communication line (including wireless communication) such as the Internet, or may be distributed in a state where they are installed on any terminal.

For example, what is described herein as a single device (including what is depicted in the drawings as a single device) may be realized by multiple devices.

[0229] Furthermore, parts of one embodiment may be incorporated into other embodiments to the extent that no inconsistency arises. Furthermore, not all of the features described in this specification are essential. In particular, features described in this specification but not recited in the claims are optional additional features.
