Description

Display control system and display control method

Technical Field

The present invention relates to a display control system and a display control method, and more particularly to a technique suitable for use in a display control system that controls display of a display device capable of displaying an icon display screen on which a plurality of icons selectable by touch operation are arranged.

Background

In recent years, terminals that display a screen on which a plurality of icons that can be selected by a touch operation are arranged on a touch panel have become widespread. For example, terminals such as so-called smart phones and tablet computers are widely used, in which icons corresponding to applications installed in the terminals are displayed in a row on a home screen after unlocking, and when any one of the icons is selected by a touch operation, the corresponding application is started.

In a terminal in which a plurality of icons are displayed on a touch panel in this manner, the user may select an icon by mistake. The misselection of an icon means that the user erroneously selects an icon having an appearance similar to that of the icon desired to be selected, instead of the icon desired to be selected. When such a wrong selection is made, it is necessary to perform a troublesome task of temporarily cancelling the selection of the icon and reselecting the correct icon, and therefore it is required to avoid the wrong selection of the icon as much as possible.

Patent document 1 describes the following technique for suppressing erroneous selection of an icon. That is, patent literature 1 describes a technique of suppressing the touch sensitivity for detecting selection of an icon (application icon) when the number of times that the icon is erroneously selected (misoperated) reaches a certain number of times. According to the technique of patent document 1, in order to select an icon that has been erroneously selected more than a certain number of times and therefore is likely to be erroneously selected in the future, it is necessary to strongly touch the icon for a long time, and such an icon cannot be immediately selected by a light touch, thereby making it possible to suppress erroneous selection.

Patent document 1: japanese patent laid-open publication No. 2013-175138

However, the technique of patent document 1 has the following problems: in a case where the user desires to select an icon whose touch sensitivity is suppressed, the user also needs to touch the icon strongly for a long time, which may be a cause of the user feeling troublesome.

Disclosure of Invention

The present invention has been made to solve the above-described problems, and an object of the present invention is to maintain a state in which each icon can be selected by a touch operation in a normal form, and to suppress erroneous selection of an icon.

In order to solve the above-described problem, in the present invention, when a user mistakenly selects another icon with respect to a certain icon, the user detects the selection, determines whether or not 2 different icons detected to be erroneously selected are similar, and changes the positional relationship in the icon display screen with respect to the 2 erroneously selected and similar icons.

ADVANTAGEOUS EFFECTS OF INVENTION

A typical situation in which an icon is erroneously selected is when a similar icon is arranged in a predetermined positional relationship on the icon display screen. For example, in a state where similar icons are arranged in proximity to each other, there is a case where it is not good to confirm each icon and any icon is selected, and an icon is erroneously selected, depending on a person. Further, for example, in a state where similar icons are arranged at a long distance, the icons are separated from each other, and it is difficult to compare the icons, and therefore, there is a case where an icon is erroneously selected by a person.

Based on the above, according to the present invention configured as described above, it is possible to change the positional relationship of the icons at the current time to a relationship in which erroneous selection by the user is less likely to occur for the user, and to suppress erroneous selection of icons, with respect to 2 icons that are erroneously selected and similar, that is, 2 icons that are likely to be erroneously selected by the user in the future as long as the positional relationship of the icons at the current time continues. In particular, according to the present invention, since erroneous selection of an icon is suppressed by a method of changing the position of the icon, instead of a method of suppressing the touch sensitivity of the icon or the like which affects the form of the touch operation when the icon is selected, the user can select 2 icons whose positional relationship has changed by the touch operation in the normal form.

Detailed Description

< embodiment 1 >

Hereinafter, embodiment 1 of the present invention will be described with reference to the drawings. Fig. 1 is a front view of a mobile terminal 2 configured to include a display control device 1 (fig. 2) of the present embodiment. In the present embodiment, the display control device 1 functions as a "display control system" in the scope of patent claims. The mobile terminal 2 of the present embodiment includes a plate-shaped housing and a touch panel 3 provided in a wide area on the front surface of the housing. A so-called smartphone or tablet computer corresponds to the mobile terminal 2. The touch panel 3 includes: a display panel such as a liquid crystal display or an organic EL panel, and a touch sensor that is disposed so as to overlap the display panel and detects a touch operation by a user.

In the mobile terminal 2 of the present embodiment, a lock screen is provided by the function of the OS, and after the lock is released by inputting a password, biometric authentication, or the like on the lock screen, the main screen 4 (corresponding to the "icon display screen" in the claims) is displayed. As shown in fig. 1, a substantially square icon 5 with slightly chamfered corners is disposed on the main screen 4.

The icon 5 is an icon corresponding to an application installed in the mobile terminal 2, and can be selected by tapping (touch operation). After the icon 5 corresponding to one application is tapped, the one application is started. Images variously patterned with characters, figures, symbols, colors, photographs, and the like are recorded on the icons 5, and the icons can be recognized by the images. Hereinafter, the image recorded in each icon is referred to as an "icon image". Note that, normally, a character string indicating a corresponding application is recorded below each icon on the home screen 4, but it is omitted in fig. 1 and other drawings.

In the home screen 4, positions where the icons 5 can be arranged (hereinafter referred to as "arrangement points") are predetermined, and each icon is arranged at a certain arrangement point. In the main screen 4 of fig. 1, there are 4 arrangement points per 1 line. In the present embodiment, icons are arranged so as to cover the arrangement points from the uppermost row downward, and in each row, icons are arranged so as to cover the arrangement points from the leftmost arrangement point to the right. However, the rule for arranging the icons depends on the specification of the OS and the setting of the user, and is not limited to the rule exemplified in the present embodiment. For example, an arbitrary icon 5 may be arranged at an arbitrary arrangement point.

The home screen 4 has a plurality of pages, and the pages can be shifted by sliding. In addition, different icons 5 can be arranged for each of the different plural pages. In addition, it is not necessary to cover all the layout points of the existing pages in order to arrange the icons 5 in the new page.

The user can manually change the position of the icon 5 on the home screen 4. More specifically, the user can move the icon 5 to a place where the icon 5 can be placed among place points of an arbitrary page by dragging & dropping a desired icon 5. When a certain icon 5 moves, the other icon 5 moves according to the OS specification in accordance with the movement.

Here, although an icon image is recorded on each icon 5, the icon images may be similar in appearance. Hereinafter, the icon images may be similarly expressed simply as "icon 5 similar" for 2 different icons 5. As described above, the icon images are used to identify the icon 5, but when the icon images are similar, the user may erroneously select the icon 5. The erroneous selection of the icon 5 means that the user erroneously selects an icon having a similar appearance to the icon desired to be selected, instead of selecting the icon desired to be selected. When a certain icon 5 is erroneously selected, it is necessary to temporarily stop the application corresponding to the icon 5 and reselect the correct icon 5, and therefore, erroneous selection of the icon 5 may cause a user to feel troublesome. Therefore, it is required to avoid erroneous selection of the icon 5 as much as possible. One of the purposes of the display control device 1 of the present embodiment is to suppress erroneous selection of the icon 5.

Fig. 2 is a block diagram showing an example of a functional configuration of the mobile terminal 2 including the display control device 1 according to the present embodiment. As shown in fig. 2, the mobile terminal 2 includes a touch panel 3, and as a functional configuration, a collective control unit 7, an erroneous selection detection unit 8, a similarity determination unit 9, and an icon position control unit 10. Each of the functional blocks 7 to 10 may be configured by any one of hardware, dsp (digital Signal processor), and software. For example, when the functional blocks 7 to 10 are configured by software, they are actually configured by a CPU, a RAM, a ROM, or the like of a computer, and are realized by program operations stored in a recording medium such as a RAM, a ROM, a hard disk, or a semiconductor memory. The same applies to other functional blocks described later. In the present embodiment, a device including the erroneous selection detection unit 8, the similarity determination unit 9, and the icon position control unit 10 functions as the display control device 1.

As shown in fig. 2, the mobile terminal 2 includes a storage unit 11 as a storage medium. The data stored in the storage unit 11 will be described later.

The overall control unit 7 controls each unit of the mobile terminal 2 by the functions of the OS-related program and other programs. For example, the overall control unit 7 drives the display panel of the touch panel 3 to display various images on the display panel. The overall control unit 7 inputs a detection value of a touch sensor of the touch panel 3, detects a touch operation, and executes a process corresponding to the detected touch operation.

Further, the overall control unit 7 updates the icon management list stored in the storage unit 11 as appropriate. The icon management list is a list in which image data of the icon 5 and arrangement position information indicating the arrangement position of the icon 5 are described in association with identification information for identifying an application for each application installed in the mobile terminal 2. Hereinafter, the discrimination information for discriminating the application is referred to as "icon ID" based on the situation that the application can be used for discriminating the icon 5 at the same time. The image data of the icon 5 is referred to as "icon image data". The placement position of the icon 5 includes information for specifying the page of the home screen 4 on which the icon 5 is placed and information for specifying the placement point on the page at which the one icon 5 is placed. The overall control unit 7 adds or deletes a record in the icon management list in accordance with the addition or deletion of the application program, and changes the value of the arrangement position information of the corresponding record in accordance with the movement of the position of the icon 5.

When a certain icon 5 is selected by the user while the home screen 4 is displayed, the overall control unit 7 outputs selection notification information including the icon ID of the icon 5 to the erroneous selection detection unit 8. When the started application is stopped (closed), the collective control unit 7 outputs stop notification information including the icon ID of the stopped application to the erroneous selection detection unit 8. The stop of the application corresponding to a certain icon 5 corresponds to "stop of the operation by selection of the icon" in the scope of patent claims. The overall control unit 7 changes the arrangement position of the icons 5 on the main screen 4 according to the control of the icon position control unit 10. The change of the arrangement position of the icon 5 will be described in detail later.

The erroneous selection detection unit 8 detects that the user mistakenly selects another icon 5 with another icon 5 based on the touch operation on the certain icon 5 and the touch operation on another icon 5. In particular, when the user selects one icon 5 and then the other icon 5 is selected after the one icon 5 is ended within a predetermined time period, the erroneous selection detection unit 8 detects that the user has selected the one icon 5 by mistake between the one icon 5 and the other icon 5. The operation of the erroneous selection detection unit 8 will be described below.

The wrong selection detecting unit 8 monitors whether or not the selection notifying information is input from the overall control unit 7. When the selection notification information is input, the wrong selection detection unit 8 acquires an icon ID included in the input selection notification information. The icon ID is the icon ID of the icon 5 newly selected by the user. Hereinafter, the icon ID included in the input selection notification information is referred to as a "first selection icon ID", and the icon of the first selection icon ID is referred to as a "first selection icon". Next, the erroneous selection detection unit 8 starts measurement of the elapsed time from the input of the selection notification information. Next, the erroneous selection detecting unit 8 monitors whether or not the elapsed time has reached a predetermined time T1, and also monitors whether or not stop notification information including the first-selected icon ID is input from the collective control unit 7.

The case where the time elapsed since the input of the selection notification information reaches the time T1 without the input of the stop notification information including the first-time selection icon ID is the case where the time T1 elapses without the application being stopped after the user starts the application for which the icon ID was first selected. In this case, the erroneous selection detection unit 8 determines that the first-time selected icon is not an erroneously selected icon.

On the other hand, when the stop notification information including the first selection icon ID is input from the collective control unit 7 before the elapsed time from the input of the selection notification information reaches the time T1, the user selects the first selection icon and starts the corresponding application, and then stops the started application within the time T1. In this case, the false selection detecting unit 8 further executes the following processing.

That is, the erroneous selection detection unit 8 starts measurement of the elapsed time from the input of the stop notification information. Next, the erroneous selection detecting unit 8 monitors whether or not the elapsed time has reached a predetermined time T2, and also monitors whether or not selection notification information including an icon ID having a value different from the first selected icon ID is input from the collective control unit 7. The case where the time elapsed since the input of the stop notification information reaches the time T2 without the input of the selection notification information including the icon ID having a value different from the value of the icon ID selected for the first time is the case where the time T2 elapses without newly starting the application program different from the application program whose icon ID was selected for the first time after the application program is stopped. In this case, the erroneous selection detection unit 8 determines that the first-time selected icon is not an erroneously selected icon.

On the other hand, the case where the selection notification information including the icon ID having a value different from the first selected icon ID is input before the elapsed time from the input of the stop notification information reaches the time T2 is a case where the user has selected the icon 5 different from the first selected icon within the time T2 after stopping the application program for which the icon ID was first selected. In this case, the icon ID included in the selection notification information is hereinafter referred to as "next selection icon ID", and the icon 5 of the next selection icon ID is hereinafter referred to as "next selection icon". In this case, the erroneous selection detection unit 8 detects that the user mistakenly selects the first selection icon with the next selection icon and selects the first selection icon. The combination of the first selection icon and the next selection icon corresponds to the combination of the 1 st icon and the 2 nd icon in the scope of patent claims.

The reason why the erroneous selection of the icon 5 is detected by the above-described processing (that is, the user mistakenly selects the first-time selection icon and the next-time selection icon) is as follows. That is, when the corresponding application is stopped within time T1 after the first selection icon is selected, the following contents can be estimated. Namely, it is estimated that: although the user has no intention of selecting the first selection icon, the first selection icon is erroneously selected, and the application is stopped in response to the start of the application by immediately perceiving the erroneous selection of the first selection icon. However, at this point in time, it is not known whether the user has an intention to select an icon 5 different from the icon selected for the first time or whether the user has no intention to select an icon 5 different from the icon selected for the first time. The time T1 is set based on a test or simulation in advance from the viewpoint of the time required until the user perceives an error when the user erroneously selects the icon 5. For example, the time T1 is about 3 seconds.

When the next selection icon is selected within time T2 after the application corresponding to the first selection icon is stopped, the following contents can be estimated. That is, it is assumed that the user originally has an intention to select the next selection icon, and therefore, the next selection icon is selected immediately after the application corresponding to the first selection icon is stopped. The time T2 is set based on a test or simulation in advance from the viewpoint of the time required for the user to select the correct icon 5 after stopping the application corresponding to the erroneously selected icon 5. For example, the time T2 is about 3 seconds. This is the reason why the erroneous selection of the icon 5 is detected by the above-described processing.

When the erroneous selection detection unit 8 detects that the user mistakenly selects the first selected icon with the next selected icon and selects the first selected icon, it outputs erroneous detection notification information including the first selected icon ID of the first selected icon and the next selected icon ID of the next selected icon to the similarity determination unit 9.

The similarity determination unit 9 determines whether or not the 2 different icons 5 (the first selected icon and the next selected icon) detected as being erroneously selected by the erroneous selection detection unit 8 are similar. Hereinafter, the processing of the similarity determination section 9 will be described by taking 2 examples.

< example 1 of processing by the similarity determination section 9 >

First, example 1 will be explained. In example 1, the similarity determination unit 9 acquires the first selected icon ID and the next selected icon ID included in the false detection notification information when the false detection notification information is input from the false detection unit 8. Next, the similarity determination section 9 accesses the icon management list stored in the storage section 11.

Next, the similarity determination unit 9 acquires the icon image data of the first selected icon ID and the icon image data of the next selected icon ID from the list using the first selected icon ID and the next selected icon ID as keys. Next, the similarity determination unit 9 analyzes the icon image data of the first selected icon ID (hereinafter referred to as "first selected icon image data") and the icon image data of the next selected icon ID (hereinafter referred to as "next selected icon image data"), and thereby determines whether or not (the icon image of) the first selected icon is similar to (the icon image of) the next selected icon.

For example, the similarity determination unit 9 determines whether or not the first selected icon is similar to the next selected icon by an existing technique of determining the similarity between 2 pieces of image data, such as histogram comparison, matching of feature points, and image analysis using local feature amounts. In the case of describing a simplified example with respect to the histogram comparison in the above example, the similarity determination unit 9 generates a histogram in which the luminance of the red component of all pixels of an image is defined as a section and the number of pixels of each luminance is defined as a frequency for both the first-time selection icon image data and the next-time selection icon image data. Then, the similarity determination unit 9 calculates the similarity between the histogram relating to the first selected icon image data and the histogram relating to the next selected icon image data, and determines that the first selected icon is similar to the next selected icon when the similarity is equal to or greater than a predetermined threshold value. It is needless to say that a plurality of techniques may be used in combination or at least some of the techniques may use a technique related to artificial intelligence. The similarity determination unit 9 may communicate with an external server via a network, and perform similarity determination using image data in cooperation with the external server.

< example 2 of processing by the similarity judging section 9 >

Next, example 2 will be explained. In example 2, the similarity determination unit 9 acquires the first selected icon ID and the next selected icon ID included in the false detection notification information when the false detection notification information is input from the false detection unit 8. Next, the similarity determination unit 9 refers to the icon similarity relationship list stored in the storage unit 11. In the icon similarity relationship list, the icon ID of the similar icon 5 is described in association with the icon ID for each application installed in the mobile terminal 2. For example, in the icon similarity relationship list, for a certain icon I, the icon ID of each icon 5 of the icons 5 similar to the icon I is described in association with the icon ID of the icon I (in some cases, there are not 1 icon, and there are a plurality of icons).

The similarity determination unit 9 determines whether or not the first selected icon is similar to the next selected icon by referring to the icon similarity relationship list and determining whether or not the next selected icon ID is included in the icon IDs described in association with the first selected icon ID in the list.

The icon similarity relationship list is updated as appropriate by the similarity determination unit 9 communicating with an external server that manages the similarity relationship between icons via a network. In this regard, the portable terminal 2 may be configured to obtain information necessary for similarity determination by communicating with an external server via a network by the similarity determination unit 9 without storing the icon similarity relationship list.

When it is determined that the first selected icon is not similar to the next selected icon as a result of the similarity determination performed by the processing illustrated in example 1 and the processing illustrated in example 2, the similarity determination unit 9 does not output similarity determination notification information, which will be described later, to the icon position control unit 10. In this case, the process of changing the position of the icon 5 by the icon position control unit 10 is not executed.

On the other hand, when it is determined that the first-time selected icon is similar to the next-time selected icon, the similarity determination section 9 outputs similarity determination notification information, which includes the first-time selected icon ID and the next-time selected icon ID and notifies that the first-time selected icon is determined to be similar to the next-time selected icon, to the icon position control section 10.

The icon position control unit 10 changes the positional relationship on the icon display screen between the first selection icon and the next selection icon which are different 2 icons determined to be similar by the similarity determination unit, and which are detected as 2 erroneously selected icons 5 by the erroneous selection detection unit 8.

When the similarity determination notification information is input, the icon position control unit 10 acquires the first selection icon ID and the next selection icon ID included in the similarity determination notification information. Next, the icon position control unit 10 executes the position changing process based on the acquired first selected icon ID and next selected icon ID. Hereinafter, 3 modes of the position changing process will be described.

< configuration 1 of the position changing processing >

First, the 1 st embodiment will be explained. The icon position control unit 10 accesses the icon management list stored in the storage unit 11, and acquires the arrangement position information of the first selected icon and the arrangement position information of the next selected icon using the first selected icon ID and the next selected icon ID as keywords. Next, the icon position control unit 10 identifies the arrangement position of each icon 5 based on the acquired arrangement position information of each icon 5. Next, the icon position control section 10 determines whether or not the positional relationship between the first selected icon and the next selected icon is in a proximity state.

In the present embodiment, when another icon 5 is located adjacent to one of the 4 directions of the left and right and the top and bottom of one icon 5, it is assumed that the position of the one icon 5 is adjacent to the position of the other icon 5. Fig. 3 is a diagram in which arrangement points of the main screen 4 are indicated by broken line frames for explaining the proximity state in the present embodiment. In fig. 3, it is assumed that one icon 5 is arranged at a configuration point X2-2. In this case, in the present embodiment, when another icon is arranged at any one of the arrangement points X1-2, X2-1, X2-3, and X3-2, the positional relationship between the one icon 5 and the other icon 5 is in a proximity state. However, the proximity state is not limited to the state exemplified in the present embodiment. For example, with reference to FIG. 3, configuration points X2-1, X2-3 may be set to a proximity state with respect to configuration point X2-2.

When it is determined that the positional relationship between the first selected icon and the next selected icon is not in the proximity state as a result of the determination as to whether or not the positional relationship is in the proximity state, the icon position control unit 10 does not output position change instruction information, which will be described later, to the collective control unit 7. In this case, the position of the icon 5 is not changed by the overall control unit 7. On the other hand, when it is determined that the state is the proximity state, the icon position control unit 10 executes the following processing.

That is, the icon position control unit 10 determines the placement point of the movement destination of 1 or 2 icons 5 to move at least one of the icons 5 so that the relationship between the placement position of the icon selected for the first time and the placement position of the icon selected next time is not in the vicinity. In the present embodiment, the icon position control unit 10 determines a new arrangement point of at least one of the icons 5 so that another 1 icon 5 is sandwiched between the first selected icon and the next selected icon.

For example, referring to FIG. 3, the first selected icon is arranged at arrangement point X1-1, and the next selected icon is arranged at arrangement point X2-1. In this case, the icon position control unit 10 determines the next icon to be selected, which is located at the arrangement point X2-1, as the icon 5 to be moved, and determines the destination of the movement as the arrangement point X3-1. If the next selection icon is moved in this way, 1 icon 5 is sandwiched between the first selection icon and the next selection icon after the movement. For example, referring to fig. 3, the first selection icon is arranged at arrangement point X1-1, and the next selection icon is arranged at arrangement point X1-2. In this case, the icon position control unit 10 determines the next selected icon arranged at the arrangement point X1-2 as the icon 5 to be moved, and determines the destination of the movement as the arrangement point X1-3.

In the present embodiment, the icon position control unit 10 determines the destination of the icon 5 in such a rule that another 1 icon 5 is sandwiched between the first selected icon and the next selected icon, but the rule is not limited to the illustrated rule. For example, the icon position control unit 10 may be configured to determine the arrangement point of at least one of the icons 5 so that the first selected icon and the next selected icon are arranged at positions that are obliquely shifted from each other. For example, referring to fig. 3, when the first selected icon is arranged at arrangement point X1-1 and the next selected icon is arranged at arrangement point X2-1 (or arrangement point X1-2), the moving destination of the next selected icon may be determined as arrangement point X2-2. When the next selection icon is moved in this way, the first selection icon and the moved next selection icon are arranged at positions that are obliquely shifted from each other, and the proximity of these icons 5 is released. Alternatively, the icon position control unit 10 may be configured to determine the destination of movement of at least one of the icons 5 so that the first selected icon and the next selected icon are arranged on different pages.

The icon position control unit 10 generates position change instruction information after determining the icon 5 to be moved from among the first selected icon and the next selected icon and further determining the arrangement point of the destination of the movement. The position change instruction information includes a combination of the icon ID of the icon 5 determined to be moved and information for specifying the placement point of the destination of the movement, and is information for instructing the movement of the icon 5. Next, the icon position control unit 10 outputs the generated position change instruction information to the collective control unit 7. The above processing is the position changing processing of the 1 st embodiment. As will be clear later, the overall control unit 7 changes the positional relationship between the first selected icon and the next selected icon on the home screen 4 based on the position change instruction information. In addition, the process of generating the position change instruction information and outputting the position change instruction information to the overall control unit 7 by the icon position control unit 10 corresponds to the process of "changing the positional relationship in the icon display screen with respect to the 1 st icon and the 2 nd icon" in the scope of patent claims.

When the position change instruction information is input from the icon position control unit 10, the overall control unit 7 executes the following processing. That is, the overall control unit 7 acquires information (hereinafter referred to as "destination information") indicating "a combination of an icon ID and information for specifying a placement point" included in the position change instruction information. When the icon position control unit 10 determines that both the first selection icon and the next selection icon are to be moved, there are 2 pieces of destination information. Next, the summary control unit 7 moves the icon 5 of the designated icon ID to the designated arrangement point based on the destination information. When the icon 5 of the designated icon ID moves to the designated arrangement point, the positional relationship between the first selected icon and the next selected icon changes, and the proximity state is released.

For example, referring to fig. 3, when the destination information indicates a combination of the icon ID of the next selected icon and the information for specifying the arrangement point X3-1, the collective control unit 7 changes the position of the next selected icon to the arrangement point X3-1. The movement of the icon 5 by the overall control unit 7 is appropriately performed by using the function of the OS. In response to the movement of at least one of the first selected icon and the next selected icon, the positions of the other icons 5 are appropriately moved in accordance with the specification of the OS.

When the position changing process of embodiment 1 is performed, the following effects are obtained. That is, when the user has performed an erroneous operation for 2 icons 5 that are similar and have a positional relationship in the proximity state, there is a possibility that the following situation will occur. That is, it may be: since the similar icons are in the adjacent state, the user does not easily confirm each icon 5 and selects any icon 5, and erroneously selects an icon 5. Therefore, if the icons 5 are released from the proximity state by separating the icons 5 of 2 related to the erroneous selection by a distance to the extent that at least the other icon 5 is sandwiched by the other icons 5, it is expected that the erroneous selection between the icons 5 will be reduced. As described above, according to the position changing process of the 1 st aspect, when the icons 5 are erroneously selected due to one of the factors that the similar 2 icons 5 are in the adjacent state, it is possible to reduce the erroneous selection between the icons 5.

< configuration 2 of the position changing process >

Next, the 2 nd embodiment of the position changing process will be described. The icon position control unit 10 accesses the icon management list stored in the storage unit 11, and recognizes the arrangement positions of the first selected icon and the next selected icon in the same manner as in the 1 st embodiment. Next, the icon position control section 10 determines whether or not the positional relationship between the first selected icon and the next selected icon is in a distant state.

In the present embodiment, the icon position control unit 10 determines that each icon 5 is in the distant state when the first selection icon and the next selection icon are arranged on different pages. However, the remote state is not limited to the state exemplified in the present embodiment. For example, even when the first selection icon and the next selection icon are arranged on a common page, if a condition such as a gap of 3 lines or more in the vertical direction, a gap of 3 lines or more in the left-right direction, or the like is satisfied, it can be determined that the positional relationship of each icon 5 is in the distant state. That is, the distant state is defined in advance from the viewpoint of whether or not the positions of the similar 2 icons 5 are separated by a distance to such an extent that the user cannot simultaneously compare the icon images of the 2 icons 5.

When it is determined that the icon is not in the distant state as a result of determining whether or not the relationship between the arrangement position of the first selected icon and the arrangement position of the next selected icon is in the distant state, the icon position control unit 10 does not output the position change instruction information to the collective control unit 7. On the other hand, when it is determined that the distance state is the distant state, the icon position control unit 10 executes the following processing. That is, the icon position control unit 10 determines the arrangement point of the movement destination of 1 or 2 icons 5 to move at least one of the icons 5 so that the positional relationship between the first selected icon and the next selected icon is not in the distant state. In the present embodiment, the icon position control unit 10 determines a new arrangement point of at least one icon 5 so that the first selected icon and the next selected icon are in the above-described proximity state.

In the present embodiment, the icon position control unit 10 determines the destination of the icon 5 according to the rule that the positional relationship between the first selected icon and the next selected icon is in the proximity state, but the rule is not limited to the illustrated rule. For example, the icon position control unit 10 may be configured to determine the destination of movement of at least one icon 5 so that the icons 5 are adjacent to each other in the left-right direction after the movement.

After determining the icon 5 to be moved from among the first selected icon and the next selected icon and further determining the placement point of the destination of movement, the icon position control unit 10 generates position change instruction information including a combination of the icon ID of the icon 5 determined to be moved and information for specifying the placement point of the destination of movement. Next, the icon position control unit 10 outputs the generated position change instruction information to the collective control unit 7. The above processing is the position changing processing of the 2 nd embodiment.

When the position change instruction information is input from the icon position control unit 10, the overall control unit 7 moves the icon 5 of the designated icon ID to the designated placement point based on the position change instruction information. When the icon 5 of the designated icon ID moves to the designated arrangement point, the positional relationship between the first selected icon and the next selected icon changes, and the remote state is released.

When the position changing process of embodiment 2 is performed, the following effects are obtained. That is, when the user has performed an erroneous operation for 2 icons 5 having similar 2 icons 5 and having a positional relationship in a remote state, there is a possibility that the following situation will occur. That is, it may be: similar icons are in a distant state, and therefore the user cannot compare the respective icons 5 and erroneously selects the icon 5. Therefore, if the icons 5 are brought into proximity, the icons 5 approach each other to such an extent that the icon images can be simultaneously confirmed, and it is expected that erroneous selection between the icons 5 can be reduced. As described above, according to the position change processing of the 2 nd aspect, when the icons 5 are erroneously selected because a situation in which the similar 2 icons 5 are in the distant state is one of the factors, it is possible to reduce the erroneous selection between the icons 5.

< form 3 of position changing processing >

Next, the 3 rd embodiment of the position changing process will be explained. The icon position control unit 10 accesses the icon management list stored in the storage unit 11, and recognizes the arrangement positions of the first selected icon and the next selected icon in the same manner as in the 1 st embodiment. Next, the icon position control section 10 determines whether or not the positional relationship between the first selected icon and the next selected icon is in a proximity state. In the case of the proximity state, the icon position control unit 10 generates position change instruction information for increasing the distance between the position of the first selected icon and the position of the next selected icon in the same manner as in the case of the 1 st embodiment, and outputs the position change instruction information to the collective control unit 7. The overall control unit 7 receives the input position change instruction information and separates the position of the first selected icon from the position of the next selected icon.

On the other hand, when the icon is not in the proximity state, the icon position control unit 10 determines whether or not the positional relationship between the first selected icon and the next selected icon is in the distant state. When the icon position control unit 10 is not in the remote state, the position change instruction information is not output to the overall control unit 7. On the other hand, when it is determined that the icon is in the distant state, the icon position control unit 10 generates position change instruction information instructing that the positional relationship between the first selected icon and the next selected icon is in the proximity state, in the same manner as in the 2 nd embodiment, and outputs the position change instruction information to the collective control unit 7. The overall control unit 7 receives the position change instruction information and sets the positional relationship between the first selected icon and the next selected icon to a proximity state.

When the position changing process of the 3 rd embodiment is performed, the following effects are obtained. That is, when the user has performed an erroneous operation for 2 icons 5 that are similar and have a positional relationship of being in a proximity state, the positions of the icons 5 are separated by a distance. Therefore, when the icons 5 are erroneously selected because the similar 2 icons 5 are in the adjacent state, it is possible to reduce the erroneous selection between the icons 5. On the other hand, when the user has performed an erroneous operation for 2

similar icons

5 and 2 icons 5 whose positional relationship is the distant state, the position of each icon 5 is set to the proximity state. Therefore, when the icons 5 are erroneously selected because the similar 2 icons 5 are in the distant state, it is possible to reduce the number of erroneous selections among the icons 5.

In the above, 3 modes of the position changing process have been described. The mobile terminal 2 may be configured to execute the processing in 1 predetermined form out of 3 forms, or may be configured to be able to select which form the processing is executed in by the user. In the case of the configuration that can be selected by the user, the user can select the appropriate 1 mode depending on whether the user has "a tendency to erroneously select one icon as another icon when the 2 icons 5 similar to each other are in the adjacent state", or "a tendency to erroneously select one icon as another icon when the 2 icons 5 similar to each other are in the distant state", or does not know which tendency is present.

As described above, in the mobile terminal 2 according to the present embodiment, when the user mistakenly selects another icon 5 with another icon 5, the user detects the selection, determines whether or not the different 2 icons 5 detected to have been erroneously selected are similar, and changes the positional relationship in the main screen 4 for the erroneously selected and similar 2 icons 5. According to this configuration, the positional relationship of the icons 5 at the current time can be changed to a relationship in which erroneous selection by the user is less likely to occur for 2 icons 5 that are erroneously selected and similar, that is, 2 icons 5 that are likely to be erroneously selected by the user in the future as long as the positional relationship of the icons 5 at the current time continues, and erroneous selection of the icons 5 can be suppressed by such a change.

In particular, according to the present embodiment, since erroneous selection of the icon 5 is suppressed by changing the position of the icon 5, instead of the method of suppressing the touch sensitivity of the icon 5 or the like, which affects the form of the touch operation when the icon 5 is selected, the user can select 2 icons 5 whose positional relationship has changed by the touch operation in the normal form.

Next, an operation example of the mobile terminal 2 will be described with reference to a flowchart. The flowcharts FA in fig. 4 and 5 are flowcharts showing the operation of the mobile terminal 2. As shown in the flowchart FA, the erroneous selection detection unit 8 monitors whether or not the selection notification information is input from the overall control unit 7 (step SA 1). When the selection notification information is input (yes in step SA1), the erroneous selection detecting unit 8 acquires the icon ID included in the input selection notification information (the first selected icon ID) (step SA 2). Next, the erroneous selection detection unit 8 starts measurement of the elapsed time from the input of the selection notification information (step SA 3). Next, the erroneous selection detecting unit 8 monitors whether or not the elapsed time reaches a predetermined time T1 (step SA4), and also monitors whether or not stop notification information including the first-selected icon ID is input from the collective control unit 7 (step SA 5).

When the stop notification information including the first-selected icon ID is not input and the elapsed time from the input of the selection notification information reaches time T1 (yes in step SA4), the mis-selection detecting unit 8 determines that the first-selected icon is not a mis-selected icon (step SA 6). After the process of step SA6, the flowchart FA ends.

On the other hand, when the stop notification information including the first selected icon ID is input from the overall control unit 7 before the elapsed time from the input of the selection notification information reaches the time T1 (yes in step SA5), the erroneous selection detecting unit 8 starts the measurement of the elapsed time from the input of the stop notification information (step SA 7). Next, the erroneous selection detecting unit 8 monitors whether or not the elapsed time has reached a predetermined time T2 (step SA8), and also monitors whether or not selection notification information including an icon ID having a value different from the first selected icon ID is input from the collective control unit 7 (step SA 9).

When the selection notification information including the icon ID having a value different from the first selected icon ID is not input and the elapsed time from the input of the stop notification information reaches the time T2 (yes in step SA8), the mis-selection detecting unit 8 determines that the first selected icon is not the mis-selected icon (step SA 10). After the process of step SA10, the flowchart FA ends.

On the other hand, when selection notification information including an icon ID (next selection icon ID) having a value different from the first selection icon ID is input before the elapsed time from the input of the stop notification information reaches the time T2 (yes in step SA9), the erroneous selection detecting unit 8 detects that the user mistakenly selects the first selection icon and the next selection icon and selects the first selection icon (step SA 11). Next, the erroneous selection detecting unit 8 outputs erroneous detection notification information including the first selected icon ID and the next selected icon ID to the similarity determining unit 9 (step SA 12).

The similarity determination section 9 inputs the false detection notification information (step SA 13). Next, the similarity determination unit 9 determines whether or not the 2 different icons 5 (the first selected icon and the next selected icon) detected as being erroneously selected by the erroneous selection detection unit 8 are similar (step SA 14). In the case where the first selected icon is not similar to the next selected icon (step SA 14: no), the flowchart FA ends. On the other hand, when the icons 5 are similar (yes in step SA14), the similarity determination notification information is output to the icon position control unit 10 (step SA 15).

The icon position control section 10 inputs the similarity determination notification information (step SA 16). Next, the icon position control unit 10 acquires the first selected icon ID and the next selected icon ID included in the similarity determination notification information (step SA 17). Next, the icon position control unit 10 executes the position changing process based on the acquired first selected icon ID and next selected icon ID (step SA 18).

The flowchart FB of fig. 6 is a flowchart showing the flow of the position changing process of the 1 st embodiment. As shown in fig. 6, the icon position control unit 10 accesses the icon management list stored in the storage unit 11, and acquires the arrangement position information of the first selected icon and the arrangement position information of the next selected icon using the first selected icon ID and the next selected icon ID as keys (step SB 1). Next, the icon position control unit 10 identifies the arrangement position of each icon 5 based on the acquired arrangement position information of each icon 5 (step SB 2). Next, the icon position control section 10 determines whether or not the positional relationship between the first selected icon and the next selected icon is in the proximity state (step SB 3).

In the case of not being in the proximity state (step SB 3: NO), the flowchart FB ends. On the other hand, when the icon is in the proximity state (yes in step SB3), the icon position control unit 10 determines to move at least one of the icons 5 so that the relationship between the arrangement position of the icon selected for the first time and the arrangement position of the icon selected next time is not in the proximity state, and determines the arrangement point of the movement destination of 1 or 2 icons 5 to be moved (step SB 4). Next, the icon position control unit 10 generates and outputs position change instruction information (step SB 5). As described above, the overall control unit 7 receives the position change instruction information from the icon position control unit 10, and changes the positional relationship between the first selected icon and the next selected icon based on the position change instruction information.

The flowchart FC in fig. 7 is a flowchart showing the flow of the position change processing in the 2 nd embodiment. As shown in fig. 7, the icon position control unit 10 accesses the icon management list stored in the storage unit 11, and acquires the arrangement position information of the first selected icon and the arrangement position information of the next selected icon using the first selected icon ID and the next selected icon ID as keys (step SC 1). Next, the icon position control unit 10 identifies the arrangement position of each icon 5 based on the acquired arrangement position information of each icon 5 (step SC 2). Next, the icon position control unit 10 determines whether or not the relationship between the arrangement position of the first selected icon and the arrangement position of the next selected icon is in the distant state (step SC 3).

In the case of not the distant state (step SC 3: no), the flowchart FC ends. On the other hand, in the case of the distant state (yes in step SC3), the icon position control unit 10 determines to move at least one of the icons 5 so that the relationship between the arrangement position of the icon selected for the first time and the arrangement position of the icon selected next time is not the distant state but the adjacent state, and determines the arrangement point of the movement destination of 1 or 2 icons 5 to be moved (step SC 4). Next, the icon position control unit 10 generates and outputs position change instruction information (step SC 5).

The flowchart FD of fig. 8 is a flowchart showing the flow of the position change processing of the 3 rd embodiment. As shown in fig. 8, the icon position control unit 10 accesses the icon management list stored in the storage unit 11, and acquires the arrangement position information of the first selected icon and the arrangement position information of the next selected icon using the first selected icon ID and the next selected icon ID as keys (step SD 1). Next, the icon position control unit 10 identifies the arrangement position of each icon 5 based on the acquired arrangement position information of each icon 5 (step SD 2). Next, the icon position control unit 10 determines whether or not the relationship between the arrangement position of the first selected icon and the arrangement position of the next selected icon is in the proximity state (step SD 3).

When the icons are in the adjacent state (step SD 3: YES), the icon position control part 10 determines to move at least one of the icons 5 so as to separate the first selected icon from the next selected icon, and determines the arrangement point of the destination of the moved icon 5 of 1 or 2 (step SD 4). Next, the icon position control unit 10 generates and outputs position change instruction information (step SD 5). After the process of step SD5, the flowchart FD ends.

If the icon is not in the proximity state (NO in step SD3), the icon position control part 10 determines whether or not the relationship between the arrangement position of the icon selected for the first time and the arrangement position of the icon selected next time is in the remote state (step SD 6). In the case where it is not in the remote state (step SD 6: NO), the flowchart FD ends. In the case of the distant state (step SD 6: YES), the icon position control part 10 determines at least one of the icons 5 to be moved so that the relationship between the arrangement position of the icon selected for the first time and the arrangement position of the icon selected next time is not the distant state but the adjacent state, and determines the arrangement point of the movement destination of 1 or 2 icons 5 to be moved (step SD 7). Next, the icon position control unit 10 generates and outputs position change instruction information (step SD 8).

< modification of embodiment 1 >

Next, a modification of embodiment 1 will be described. In the above-described embodiment 1, the following configuration is adopted: the icon position control unit 10 changes the positional relationship of each icon 5 only when the positional relationship of each icon 5 is in a predetermined state (proximity state, remote state, or "proximity state or remote state") with respect to the first selection icon and the next selection icon which are similar to each other. In this regard, the icon position control unit 10 may change the positional relationship of the icons 5 regardless of whether the positional relationship is in a predetermined state. In this configuration, for example, the icon position control unit 10 randomly changes the positional relationship, and for example, the icon position control unit 10 changes the positional relationship according to a predetermined rule. Even in this configuration, the positional relationship can be changed for 2 icons 5 that can be erroneously selected by the user in the future as long as the positional relationship of each icon 5 at the current time continues, and the possibility of erroneous selection can be reduced.

In addition, in embodiment 1 described above, the following configuration is adopted: the icon position control unit 10 changes the positional relationship of each icon 5 for the first selected icon and the next selected icon even when the user erroneously selects the first selected icon and the next selected icon. In this regard, the following configuration is also possible: when the user erroneously selects 2 icons 5 more than a predetermined number of times, the icon position control unit 10 changes the positional relationship of the icons 5. With this configuration, it is possible to prevent unnecessary changes in the positional relationship for 2 icons 5 that are accidentally selected and have a low possibility of being selected by the user in the future.

< embodiment 2 >

Next, embodiment 2 will be explained. In the following description of embodiment 2, the same elements as those of embodiment 1 are denoted by the same reference numerals as those of embodiment 1, and detailed description thereof will be omitted. Fig. 9 is a block diagram showing an example of the functional configuration of the portable terminal 2A including the display control device 1A according to embodiment 2 and the in-vehicle device 20 that can communicate with the portable terminal 2A. In the present embodiment, the display control device 1A functions as a "display control system" in the scope of patent claims. The in-vehicle device 20 is mounted on a vehicle, and includes an in-vehicle touch panel 21 for allowing a driver or other occupants to visually recognize the device. The mobile terminal 2A according to the present embodiment is a device that a vehicle occupant brings into the vehicle.

As shown in fig. 9, the mobile terminal 2A includes a collective control unit 7A instead of the collective control unit 7. The mobile terminal 2A includes a storage unit 11A instead of the storage unit 11. The mobile terminal 2A includes a communication unit 22 as a functional configuration. The display control device 1A includes a similarity determination unit 9A instead of the similarity determination unit 9, and an icon position control unit 10A instead of the icon position control unit 10. The display control device 1A further includes a tendency detection unit 23. As shown in fig. 9, the in-vehicle device 20 includes an in-vehicle touch panel 21, and further includes a communication unit 25 and an in-vehicle control unit 26 as functional components. The touch panel 3 of the portable terminal 2A corresponds to the "1 st display device" in the scope of patent claims, and the in-vehicle touch panel 21 of the in-vehicle device 20 corresponds to the "2 nd display device" in the scope of patent claims.

The communication unit 22 of the portable terminal 2A and the communication unit 25 of the in-vehicle device 20 establish a connection state in accordance with a predetermined communication standard and communicate in accordance with the predetermined communication standard. The communication may be wireless or wired, and the communication standard may be any communication standard. The in-vehicle control unit 26 of the in-vehicle device 20 collectively controls the respective units of the in-vehicle device 20.

In embodiment 2, the icon position control unit 10A of the mobile terminal 2A executes the position change processing in the 3 rd mode. The icon position control unit 10A executes the following processing in the position change processing. That is, the storage unit 11A stores the recording data. The recorded data includes a1 st variable that manages the number of times position change instruction information (hereinafter, referred to as "separation instruction information" for convenience) is output, and the position change instruction information (hereinafter, referred to as "separation instruction information" for convenience) instructs to separate the position of the first selected icon from the position of the next selected icon. In addition, the recording data includes a2 nd variable that manages the number of times position change instruction information (hereinafter, referred to as "proximity instruction information" for convenience) is output, and the position change instruction information (hereinafter, referred to as "proximity instruction information" for convenience) instructs that the position of the first selected icon and the position of the next selected icon are in a state of proximity to each other. In addition, the recorded data describes the 3 rd variable that manages the number of times that the user erroneously selected the similar icon 5 and the positional relationship of each icon 5 is neither in the proximity state nor in the remote state. The initial values of the 1 st variable, the 2 nd variable, and the 3 rd variable are all "0".

The icon position control unit 10A executes the following processing each time the similarity determination notification information is input from the similarity determination unit 9A. That is, when the positional relationship between the first selected icon and the next selected icon is in the proximity state and the separation instruction information is output, the 1 st variable is increased. The icon position control unit 10A increases the 2 nd variable when the positional relationship between the first selected icon and the next selected icon is in the distant state and the proximity instruction information is output. The icon position control unit 10A increases the 3 rd variable when the positional relationship between the first selected icon and the next selected icon is neither in the close state nor in the distant state and the position change instruction information is not output.

As a result, in the recorded data, the number of times the separation instruction information is output when the similar 2 icons 5 are erroneously selected, the number of times the proximity instruction information is output in this case, and the number of times the position change instruction information is not output in this case are managed. Further, since the position change instruction information is output after determining the detection result of the erroneous selection detecting unit 8 and the determination result of the similarity determining unit 9, the record data corresponds to "a history reflecting the detection result of the erroneous selection detecting unit and the determination result of the similarity determining unit" in the scope of patent claims.

In the present embodiment, the following configuration is adopted: after the connection state between the portable terminal 2A and the in-vehicle device 20 is established, communication is performed between the collective control unit 7A and the in-vehicle control unit 26, and the icon 5 included in the icon 5 disposed on the main screen 4 of the portable terminal 2A is displayed on the home screen MG of the in-vehicle touch panel 21 of the in-vehicle device 20. The icon 5 displayed on the top screen MG of the in-vehicle touch panel 21 can be selected by a touch operation, and when selected, the corresponding application program in the mobile terminal 2A is started.

In the present embodiment, the arrangement form of the arrangement points on the touch panel 3 of the portable terminal 2A is different from the arrangement form of the arrangement points on the in-vehicle touch panel 21 of the in-vehicle device 20. For example, the touch panel 3 of the portable terminal 2A has 4 placement points for every 1 line, while the touch panel 3 of the in-vehicle device 20 has 6 placement points for every 1 line. Further, not all of the icons 5 arranged on the home screen 4 of the mobile terminal 2A are displayed on the in-vehicle touch panel 21, but a part of the icons 5 are prohibited from being displayed on the in-vehicle touch panel 21 under the control of the collective control unit 7A. The icon 5 prohibited from being displayed on the in-vehicle touch panel 21 is, for example, an icon corresponding to an application determined in advance as an inappropriate application that is started in a state where the mobile terminal 2A is connected to the in-vehicle device 20, and is, for example, an icon 5 set in advance by the user. Due to this, the icons 5 are not arranged on the in-vehicle touch panel 21 of the in-vehicle device 20 in the same arrangement as when displayed on the touch panel 3 of the portable terminal 2A. Based on the above, the mobile terminal 2A of the present embodiment executes the following processing.

When the connection state is established between the communication unit 22 of the portable terminal 2A and the communication unit 25 of the in-vehicle device 20, the overall control unit 7A of the portable terminal 2A detects this. When it is detected that the connection state is established, the overall control unit 7A determines candidates for the arrangement pattern in the home screen MG of the in-vehicle touch panel 21, with respect to the icons 5 stored in the home screen 4 of the portable terminal 2A, according to a predetermined rule. The overall control unit 7A determines candidates of the arrangement form of the icons 5 in the top screen MG of the in-vehicle touch panel 21, taking into account the arrangement form of the icons 5 prohibited from being displayed on the in-vehicle touch panel 21 and the arrangement points in the in-vehicle touch panel 21.

Fig. 10 (a) is a diagram showing an example of the main screen 4 of the mobile terminal 2A. In fig. 10a (and fig. 10B and C) as well, the icon images of some of the icons 5 are not drawn. Fig. 10 (B) shows an example of candidates for the arrangement of the icons 5 in the home screen MG. When the icons 5 are arranged in the arrangement pattern exemplified in fig. 10 (a) on the main screen 4 of the mobile terminal 2A, for example, the collective control unit 7A sets the candidates for the arrangement pattern of the icons 5 on the top screen MG of the in-vehicle touch panel 21 to the arrangement pattern shown in fig. 10 (B). Hereinafter, the candidate of the arrangement form of the icons 5 on the top screen MG of the in-vehicle touch panel 21 will be simply referred to as "candidate arrangement form".

Next, the overall control unit 7A outputs, to the index position control unit 10A, arrangement form determination request information including information indicating a candidate arrangement form and requesting determination of an arrangement form. The information indicating the candidate arrangement form is, for example, information having a combination of an icon ID and information for specifying an arrangement point where the icon 5 is arranged, for each icon 5 of the icons 5 arranged on the home screen MG of the in-vehicle touch panel 21.

The icon position control unit 10A executes the position adjustment process when the arrangement form determination request information is input. The position adjustment process will be described in detail below. In the position adjustment processing, first, the icon position control unit 10A inquires of the tendency detection unit 23 whether or not the 1 st tendency or the 2 nd tendency is present (the 1 st tendency and the 2 nd tendency are described later).

When there is an inquiry from the icon position control unit 10A, the tendency detection unit 23 executes the following processing. In other words, the tendency detection unit 23 refers to the recording data stored in the storage unit 11A. Next, the tendency detection unit 23 acquires (the value of) the 1 st variable, (the value of) the 2 nd variable, and (the value of) the 3 rd variable. Next, the tendency detection unit 23 calculates the ratio of the 1 st variable to the sum of the 1 st variable, the 2 nd variable and the 3 rd variable (1 st variable/(1 st variable + 2 nd variable + 3 rd variable) — hereinafter referred to as "1 st ratio"). Next, the tendency detection unit 23 determines whether or not the 1 st ratio is equal to or greater than the 1 st threshold.

The 1 st ratio means a ratio of the number of times the user has made a wrong selection of 2 icons 5 in the proximity state among the number of times the user has selected similar 2 icons 5 by mistake in the past. Therefore, the 1 st ratio is equal to or greater than the 1 st threshold, and the user tends to make a wrong selection when the positional relationship of the similar 2 icons 5 is in the proximity state. Such a "tendency that one icon is erroneously selected as another icon when 2 icons similar to each other are in a neighboring state" corresponds to the 1 st tendency. The 1 st threshold is determined by a previous test or the like based on the property of the threshold for determining the presence or absence of the 1 st tendency.

When the 1 st ratio is equal to or greater than the 1 st threshold, the tendency detection unit 23 determines that the user has the 1 st tendency, and responds this to the icon position control unit 10A.

When the 1 st ratio is not equal to or greater than the 1 st threshold, the tendency detection unit 23 calculates the ratio of the 2 nd variable (2 nd variable/(1 st variable + 2 nd variable + 3 rd variable) — hereinafter referred to as "the 2 nd ratio") with respect to the sum of the 1 st variable and the 2 nd variable and the 3 rd variable. Next, the tendency detection unit 23 determines whether or not the 2 nd ratio is equal to or greater than the 2 nd threshold value.

The 2 nd ratio means a ratio of the number of times the user has made a wrong selection of the 2 icons 5 in the distant state among the number of times the user has selected the similar 2 icons 5 by mistake in the past. Therefore, the 2 nd ratio is equal to or greater than the 2 nd threshold, and the user tends to make a wrong selection when the positional relationship of the similar 2 icons 5 is in a distant state. Such "a tendency that one icon is erroneously selected as another icon when 2 icons similar to each other are in a distant state" corresponds to the 2 nd tendency. The 2 nd threshold is determined by a previous test or the like based on the property of the threshold for determining the presence or absence of the 2 nd tendency.

When the 2 nd ratio is equal to or greater than the 2 nd threshold, the tendency detection unit 23 determines that the user has the 2 nd tendency, and responds this to the icon position control unit 10A.

On the other hand, when the 2 nd ratio is not equal to or greater than the 2 nd threshold, the tendency detection unit 23 responds to the icon position control unit 10A that the user does not have both the 1 st tendency and the 2 nd tendency.

The icon position control unit 10A receives the response from the tendency detection unit 23, and recognizes whether the user has the 1 st tendency, the 2 nd tendency, or both the 1 st tendency and the 2 nd tendency. When the user does not have both the 1 st tendency and the 2 nd tendency, the icon position control unit 10A determines the candidate arrangement form as the final arrangement form, and notifies the overall control unit 7A of the candidate arrangement form as a response to the arrangement form determination request information.

On the other hand, when the user has the 1 st tendency, the icon position control unit 10A outputs the similarity determination unit 9A with the similarity detection request information including the information indicating the candidate arrangement form.

When the similar proximity detection request information is input, the similarity determination unit 9A performs the following detection based on the information indicating the candidate arrangement form included in the information. That is, the similarity determination unit 9A detects combinations of 2 icons 5 that are similar to each other and in a proximity state in the candidate arrangement form. In addition, there are cases where 1 of the combinations is not present, and there are cases where a plurality of combinations are present. For example, in the example of fig. 10 (B), it is assumed that the icon R1 is similar to the icon R2, and further, the icon R1 is similar to the icon R3. In this case, the positional relationship of the icon R1 and the icon R2 is a proximity relationship, and therefore the similarity determination section 9A detects the combination of the icon R1 and the icon R2 as "a combination of 2 icons 5 that are similar to each other and in a proximity state". Further, since the positional relationship between the icon R1 and the icon R3 is a proximity relationship, the similarity determination section 9A detects the combination of the icon R1 and the icon R3 as "a combination of 2 icons 5 that are similar to each other and in a proximity state".

The similarity determination unit 9A outputs information indicating the detected combination to the icon position control unit 10A as a response to the similar proximity detection request information. In addition, when there is no "combination of 2 icons 5 similar to each other and in a proximity state" in the arrangement of the icons 5 in the candidate arrangement form, information indicating that there is no combination is output to the icon position control unit 10A as a response to the similar proximity detection request information.

When the information indicating the combination is input from the similarity determination unit 9A as a response to the similarity detection request information, the icon position control unit 10A changes the contents of the candidate arrangement pattern so as to separate the 2 icons 5 included in the combination. For example, in the case of the candidate arrangement form illustrated in fig. 10 (B), the icon position control unit 10A separates the icon R1 from the icon R2 to sandwich the other 1 icon, and separates the icon R1 from the icon R3 to sandwich the other 1 icon, as shown in fig. 10 (C). Next, the icon position control unit 10A notifies the overall control unit 7A of information indicating the changed arrangement form as a response to the arrangement form determination request information.

On the other hand, when the similarity determination unit 9A receives a response indicating that the information having no combination is received as the similar proximity detection request information, the icon position control unit 10A determines the candidate arrangement form as the final arrangement form and notifies the overall control unit 7A of the candidate arrangement form as the response to the arrangement form determination request information.

When the user tends to be 2 nd, the icon position control unit 10A outputs the similar distance detection request information including the information indicating the candidate arrangement form to the similar determination unit 9A.

When the similar distance detection request information is input, the similar determining unit 9A performs the following detection based on the information indicating the candidate arrangement form included in the information. That is, the similarity determination unit 9A detects combinations of 2 icons 5 that are similar to each other and are in a distant state in the candidate arrangement form. In addition, there are cases where 1 of the combinations is not present, and there are cases where a plurality of combinations are present. Fig. 11 (a) is a diagram showing an example of the candidate arrangement pattern, and (a1) and (a2) show different pages in the home screen MG. For example, in the example of fig. 11 (a), it is assumed that the icon R4 is similar to the icon R5. In this case, since the positional relationship between the icon R4 and the icon R5 is a distant relationship, the similarity determination unit 9A detects the combination of the icon R4 and the icon R5 as "a combination of 2 icons 5 that are similar to each other and are in a distant state".

The similarity determination unit 9A outputs information indicating the detected combination to the icon position control unit 10A as a response to the similar distance detection request information. In addition, when there is no "combination of 2 icons 5 similar to each other and in a distant state" in the arrangement of the icons 5 in the candidate arrangement form, information indicating that there is no combination is output to the icon position control unit 10A as a response to the similar proximity detection request information.

When the information indicating the combination is input from the similarity determination unit 9A as a response to the similarity detection request information, the icon position control unit 10A changes the contents of the candidate arrangement form so that 2 icons 5 included in the combination are in a proximity state for each combination. For example, in the case of the example shown in fig. 11 (a), the icon position control unit 10A brings the icon R4 and the icon R5 into a state of proximity as shown in (B1) and (B2) of fig. 11 (B). Next, the icon position control unit 10A notifies the overall control unit 7A of information indicating the changed arrangement form as a response to the arrangement form determination request information.

On the other hand, when the similarity determination unit 9A receives a response indicating that the information having no combination is received as the similar proximity detection request information, the icon position control unit 10A determines the candidate arrangement form as the final arrangement form, and notifies the overall control unit 7A of the candidate arrangement form as the response to the arrangement form determination request information.

The above processing is position adjustment processing. As described above, in the position adjustment process, the icon position control unit 10 separates the positions of 2 icons similar to each other by a distance when the tendency detection unit 23 detects that the user has the 1 st tendency, and separates the positions of the 2 icons by a distance when the tendency detection unit 23 detects that the user has the 2 nd tendency, and separates the positions of the 2 icons similar to each other by a distance when the tendency detection unit 23 detects that the user has the 2 nd tendency.

When receiving a response indicating that the candidate arrangement form is the final arrangement form as a response to the arrangement form determination request information, the overall control unit 7A displays the icons 5 in the candidate arrangement form on the in-vehicle touch panel 21 in cooperation with the in-vehicle control unit 26 of the in-vehicle device 20. On the other hand, when receiving the information indicating the changed arrangement form as a response to the arrangement form determination request information, the overall control unit 7A displays the icons 5 in the candidate arrangement form on the in-vehicle touch panel 21 in cooperation with the in-vehicle control unit 26 of the in-vehicle device 20.

As a result of the above processing, when the user tends to be 1 st, the icons 5 are arranged on the touch panel 3 of the in-vehicle device 20 in an arrangement form in which similar positional relationships of the icons 5 are not in a close state. Therefore, it is possible to provide the top screen MG in which erroneous selection of the icon 5 is less likely to occur for a user who has a tendency to "erroneously select one icon as another icon when 2 icons similar to each other are in a neighboring state".

In addition, when the user tends to be 2 nd, the icons 5 are arranged on the touch panel 3 of the in-vehicle device 20 in an arrangement form in which the positional relationship of the icons 5 is not in a distant state. Therefore, it is possible to provide the top screen MG in which erroneous selection of the icon 5 is less likely to occur for a user who has a tendency to "erroneously select one icon as another icon when 2 icons similar to each other are in a neighboring state".

Next, an operation example of the mobile terminal 2A according to the present embodiment will be described with reference to a flowchart. The flow charts FE in fig. 12 and 13 are flow charts showing the operation of the mobile terminal 2A. As shown in the flowchart FE, the overall control unit 7A monitors whether or not a connection state is established between the communication unit 22 of the portable terminal 2A and the communication unit 25 of the in-vehicle device 20 (step SE 1). When the connection state is established (yes in step SE1), the overall control unit 7A determines candidates for the arrangement form in the front screen MG of the in-vehicle touch panel 21 according to a predetermined rule (step SE 2). Next, the overall control unit 7A outputs the arrangement form determination request information to the icon position control unit 10A (step SE 3).

When the arrangement form determination request information is input (step SE4), the icon position control unit 10A inquires the tendency detection unit 23 whether there is a1 st tendency or a2 nd tendency (step SE 5).

When there is an inquiry from the icon position control unit 10A, the tendency detection unit 23 refers to the record data stored in the storage unit 11A to acquire (the value of) the 1 st variable, (the value of) the 2 nd variable, and (the value of) the 3 rd variable (step SE 6). Next, the tendency detection unit 23 calculates the 1 st ratio (step SE 7). Next, the tendency detection unit 23 determines whether or not the 1 st ratio is equal to or greater than the 1 st threshold (step SE 8). When the 1 st ratio is equal to or greater than the 1 st threshold (yes in step SE8), the tendency detection unit 23 determines that the user has the 1 st tendency (step SE9), and responds this to the icon position control unit 10A (step SE 10). After the process at step SE10, the process proceeds to step SE 16.

When the 1 st ratio is not equal to or greater than the 1 st threshold (NO at step SE8), the tendency detector 23 calculates the 2 nd ratio (step SE 11). Next, the tendency detection unit 23 determines whether or not the 2 nd ratio is equal to or greater than the 2 nd threshold value (step SE 12). When the 2 nd ratio is equal to or greater than the 2 nd threshold (yes in step SE12), the tendency detection unit 23 determines that the user has the 2 nd tendency (step SE13), and responds this to the icon position control unit 10A (step SA 14). After the process at step SE14, the process proceeds to step SE 16. On the other hand, when the 2 nd ratio is not less than the 2 nd threshold (no in step SE12), the tendency detection unit 23 gives a response to the icon position control unit 10A that the user does not have both the 1 st tendency and the 2 nd tendency (step SE 15). After the process at step SE15, the process proceeds to step SE 16.

In step SE16, the icon position control unit 10A receives the response from the tendency detection unit 23, and determines whether the user has the 1 st tendency, the 2 nd tendency, or neither the 1 st tendency nor the 2 nd tendency. When the user does not have both the 1 st tendency and the 2 nd tendency (step SE 16: "no tendency"), the icon position control unit 10A determines the candidate arrangement form as the final arrangement form, and notifies the overall control unit 7A of the candidate arrangement form as a response to the arrangement form determination request information (step SE 17). After the process at step SE17, the process proceeds to step SE 32.

On the other hand, when the user has the 1 st tendency (step SE 16: "tendency 1"), the icon position control unit 10A outputs the similarity determination unit 9A with the similarity detection request information including the information indicating the candidate arrangement form (step SE 18).

The similarity determination section 9A inputs the similarity detection request information (step SE 19). The similarity determination unit 9A detects that there is no combination when the presence or absence of a combination of 2 icons 5 that are similar to each other and are in a proximity state is detected in the candidate arrangement form based on the information indicating the candidate arrangement form included in the input similar proximity detection request information (step SE 20). Next, the similarity determination unit 9A outputs information indicating the detected combination or information indicating that the combination does not exist to the icon position control unit 10A as a response to the similar proximity detection request information (step SE 21).

The icon position control unit 10A receives, as a response to the proximity detection request information, information indicating a combination or information indicating that a combination does not exist from the similarity determination unit 9A (step SE 22). When information indicating a combination is input, the icon position control unit 10A changes the contents of the candidate arrangement form so as to separate 2 icons 5 included in the combination for each combination, and when information indicating that no combination exists is input, determines the candidate arrangement form as the final arrangement form (step SE 23). Next, the icon position control unit 10A notifies the overall control unit 7A of information indicating the changed arrangement form or information indicating that the candidate arrangement form is determined as the final arrangement form as a response to the arrangement form determination request information (step SE 24). After the process at step SE24, the process proceeds to step SE 32.

When the user has the 2 nd tendency (step SE 16: "the 2 nd tendency"), the icon position control unit 10A outputs the similar distance detection request information including the information indicating the candidate arrangement form to the similar determination unit 9A (step SE 25).

The similar determination section 9A inputs similar remote sensing request information (step SE 26). The similarity determination unit 9A detects that there is no combination when a combination of 2 icons 5 that are similar to each other and are in a distant state is detected in the candidate arrangement form or when there is no such combination, based on the information indicating the candidate arrangement form included in the information (step SE 27). Next, the similarity determination unit 9A outputs information indicating the detected combination or information indicating that the combination does not exist to the icon position control unit 10A as a response to the similar distance detection request information (step SE 28).

The icon position control unit 10A receives, as a response to the proximity detection request information, information indicating a combination or information indicating that a combination does not exist from the similarity determination unit 9A (step SE 29). When information indicating a combination is input, the icon position control unit 10A changes the contents of the candidate arrangement form so that 2 icons 5 included in the combination are in a proximity state for each combination, and when information indicating that no combination exists is input, determines the candidate arrangement form as the final arrangement form (step SE 30). Next, the icon position control unit 10A notifies the overall control unit 7A of information indicating the changed arrangement form or information indicating that the candidate arrangement form is determined as the final arrangement form as a response to the arrangement form determination request information (step SE 31). After the process at step SE31, the process proceeds to step SE 32. The processing of step SE5 to step SE31 corresponds to position adjustment processing.

In step SE32, the overall control unit 7A receives a response of the arrangement form determination request information. Next, the overall control unit 7A executes processing corresponding to the content of the received response (step SE 33). Specifically, when a response is received that the candidate arrangement form is the final arrangement form, the overall control unit 7A displays the icons 5 in the candidate arrangement form on the in-vehicle touch panel 21 in cooperation with the in-vehicle control unit 26 of the in-vehicle device 20. On the other hand, when the information indicating the changed arrangement form is received, the collective control unit 7A displays the icons 5 in the changed arrangement form on the in-vehicle touch panel 21 in cooperation with the in-vehicle control unit 26 of the in-vehicle device 20.

< modification of embodiment 2 >

Next, a modification of embodiment 2 will be described. In embodiment 2 described above, the icon position control unit 10A performs the position changing process in the 3 rd mode. On the other hand, when the icon position control unit 10A performs the position change process in the 1 st embodiment, the mobile terminal 2A executes the following process.

That is, the icon position control unit 10A increases the value of the 1 st variable or the 3 rd variable of the recording data as appropriate. In the case of the 1 st aspect, since the proximity indication information is not output, the 2 nd variable is not described in the recording data. Further, in the position adjustment processing, only the presence or absence of the 1 st tendency is determined by the tendency detection unit 23. The tendency detection unit 23 determines that there is a1 st tendency when the ratio of the 1 st variable to the total of the 1 st variable and the 3 rd variable is equal to or greater than a predetermined threshold value. When there is the 1 st tendency, the content of the candidate arrangement form is changed by the icon position control unit 10A so as to separate the 2 icons 5 in the similar and adjacent state.

According to the above modification, when the user tends to be 1 st, the icons 5 are arranged on the touch panel 3 of the in-vehicle device 20 in an arrangement form in which the icons 5 are not in a close proximity in a positional relationship. Therefore, it is possible to provide the top view MG in which erroneous selection of the icon 5 is less likely to occur for the user having the 1 st tendency.

As another modification, when the icon position control unit 10A performs the position change process in the 2 nd mode, the mobile terminal 2A executes the following process. That is, the icon position control unit 10A increases the value of the 2 nd variable or the 3 rd variable of the recording data as appropriate. In the position adjustment processing, the tendency detection unit 23 determines only the presence or absence of the 2 nd tendency. The tendency detection unit 23 determines that there is a tendency 2 when the ratio of the 2 nd variable to the total of the 2 nd variable and the 3 rd variable is equal to or greater than a predetermined threshold value. In the case of the 2 nd tendency, the icon position control unit 10A changes the contents of the candidate arrangement form so that the 2 icons 5 in the similar and distant state are in the adjacent state.

According to the above modification, when the user tends to be 2 nd, the icons 5 are arranged on the touch panel 3 of the in-vehicle device 20 in an arrangement form in which the positional relationship of the icons 5 is not in a distant state. Therefore, it is possible to provide the top screen MG in which erroneous selection of the icon 5 is less likely to occur for the user having the 2 nd tendency.

In embodiment 2, the display control device 1A includes the similarity determination unit 9A, the icon position control unit 10A, and the tendency detection unit 23. In this regard, the in-vehicle control unit 26 of the in-vehicle device 20 may include at least one of 1 functional block of the similarity determination unit 9A, the icon position control unit 10A, and the tendency detection unit 23. Further, the display control device 1A may be configured to execute at least one function of 1 of the similarity determination unit 9A, the icon position control unit 10A, and the tendency detection unit 23 in cooperation with the in-vehicle device 20. When the function of the tendency detection unit 23 is incorporated in the in-vehicle device 20, the tendency detection unit 23 appropriately acquires information on the recording data stored in the storage unit 11A from the portable terminal 2A. In these cases, the display control device 1A functions as a "display control system" in the scope of patent claims in cooperation with the in-vehicle device 20.

Hereinafter, an example of the operation of the in-vehicle control unit 26 will be briefly described, taking as an example a case where the in-vehicle control unit 26 of the in-vehicle device 20 has functions similar to those of the determination unit 9A, the icon position control unit 10A, and the tendency detection unit 23.

When the connection state is established between the mobile terminal 2A and the in-vehicle device 20, the in-vehicle control unit 26 acquires necessary information on the icon 5 from the overall control unit 7A of the mobile terminal 2A, and determines a candidate for the arrangement form of the icon 5 in the home screen MG. Next, the in-vehicle control unit 26 acquires information on the recorded data from the portable terminal 2A, and determines the tendency (the 1 st tendency, the 2 nd tendency, or the no tendency) of the user. Then, the in-vehicle control unit 26 determines the candidate arrangement form as the final arrangement form when the arrangement form is not tilted. When the user tends to be 1 st, the in-vehicle control unit 26 changes the contents of the candidate arrangement pattern so as to separate the 2 icons 5 in the adjacent state. When the user tends to be 2 nd, the in-vehicle control unit 26 changes the contents of the candidate arrangement pattern so that the 2 icons 5 at a distance are close to each other. The in-vehicle control unit 26 arranges the icons 5 on the top screen MG based on the determined arrangement form.

< embodiment 3 >

Next, embodiment 3 will be explained. In the following description of embodiment 3, the same elements as those of embodiment 1 are denoted by the same reference numerals as those of embodiment 1, and detailed description thereof will be omitted.

Fig. 14 is a block diagram showing an example of a functional configuration of a mobile terminal 2B including a display control device 1B according to embodiment 3. In the present embodiment, the display control device 1B functions as a "display control system" in the scope of patent claims. As shown in fig. 14, the mobile terminal 2B includes a collective control unit 7B instead of the collective control unit 7. The mobile terminal 2B includes a storage unit 11B instead of the storage unit 11. The display control device 1B includes a similarity determination unit 9B instead of the similarity determination unit 9, and an icon position control unit 10B instead of the icon position control unit 10. The display control device 1B further includes a tendency detection unit 23B.

Here, the application may be newly installed in the mobile terminal 2B. When an application is newly installed, the icon 5 corresponding to the new application is arranged at a designated position on the home screen 4. The designated position is variously set according to the specification and setting of the OS. For example, the new icon 5 is arranged at the arrangement point next to the arrangement point related to the last icon 5 in the final page of the home screen. The mobile terminal 2B of the present embodiment executes the characteristic processing described below when a new icon 5 is placed on the home screen 4.

Here, in the present embodiment, the icon position control unit 10B executes the position changing process in the 3 rd mode. In addition, as in embodiment 2, the storage unit 11B stores record data in which the 1 st, 2 nd, and 3 rd variables are described.

When the user instructs to start installation of a new application, the overall control unit 7B adds a record to the icon management list of the storage unit 11B. In the added record, the arrangement position indicated by the arrangement position information is a specified position determined according to the specification of the OS or the like. Therefore, if the arrangement position of the new icon 5 is not adjusted, the new icon 5 is arranged at the specified position. Further, the overall control unit 7B outputs, to the icon position control unit 10B, the placement position determination request information including the icon ID of the new application program for requesting the determination of the placement position of the new icon 5. Hereinafter, the icon 5 of the new application is referred to as a "new icon", and the icon ID of the new icon is referred to as a "new icon ID".

When the arrangement position determination request information is input, the icon position control section 10B executes the position adjustment process in cooperation with the tendency detection section 23B and the similarity determination section 9B. The position adjustment process will be described in detail below. In the position adjustment processing, first, the icon position control unit 10B inquires the tendency detection unit 23B of the presence or absence of the 1 st tendency or the 2 nd tendency.

In response to the inquiry from the icon position control unit 10B, the tendency detection unit 23B determines the presence or absence of the 1 st tendency and the 2 nd tendency in the same manner as in embodiment 2, and responds to the icon position control unit 10B with any of the meanings of "having the 1 st tendency", "having the 2 nd tendency", or "the user does not have both the 1 st tendency and the 2 nd tendency".

The icon position control unit 10B receives the response from the tendency detection unit 23B, and recognizes whether the user has the 1 st tendency, the 2 nd tendency, or neither the 1 st tendency nor the 2 nd tendency. When the user does not have both the 1 st tendency and the 2 nd tendency, the icon position control unit 10B determines the designated position as the final arrangement position, and notifies the collective control unit 7B of the determined position as a response to the arrangement position determination request information.

On the other hand, when the user tends to be 1 st, the icon position control unit 10B outputs the similar proximity determination request information including the new icon ID to the similar determination unit 9B.

When the similarity determination request information is input, the similarity determination unit 9B performs the following detection based on the new icon ID included in the information. That is, the similarity determination unit 9B determines whether or not there is an icon 5 in a state adjacent to the icon 5 in the position relationship with the new icon and an icon 5 similar to the new icon (hereinafter, referred to as "close similarity icon") when the new icon is arranged at the designated position. When the proximity similar icon does not exist, the similarity determination unit 9B outputs information indicating that the proximity similar icon does not exist to the icon position control unit 10B as a response to the proximity determination request information. On the other hand, when the proximity similar icon exists, the similarity determination unit 9B outputs an icon ID of the proximity similar icon (hereinafter, referred to as "proximity similar icon ID") to the icon position control unit 10B as a response to the similar proximity determination request information. In the determination of the presence or absence of the proximity similar icon, the similarity determination unit 9B refers to the icon management list stored in the storage unit 11B as appropriate.

When information indicating that the proximity-similar icon does not exist is input from the similarity determination unit 9B as a response to the similarity determination request information, the icon position control unit 10B determines the designated position as the final arrangement position of the new icon, and outputs the determined position to the overall control unit 7B as a response to the arrangement position determination request information.

On the other hand, when the proximity similar icon ID is input as a response to the similar proximity determination request information, the icon position control unit 10B executes the following processing. That is, the icon position control unit 10B changes the arrangement position of the updated icons so that at least 1 icon 5 is sandwiched between the new icon and the proximity-similar icon, and the new icon and the proximity-similar icon are separated by a distance, and the adjacent state is released. Fig. 15 is a diagram showing an example of the main screen 4. For example, in fig. 15, the arrangement point Q151 is assumed to be a designated position. In this case, when the existing icon 5 arranged at the arrangement point Q152 is similar to the new icon, the icon position control unit 10B determines Q153 as the new arrangement position of the new icon. After changing the arrangement position of the new icon, the icon position control unit 10B notifies the collective control unit 7B of information indicating the arrangement position of the new icon after the change as a response to the arrangement position determination request information.

When the user tends to be 2 nd, the icon position control unit 10B outputs the similar distance determination request information including the new icon ID to the similar determination unit 9B.

When the similar distance determination request information is input, the similar determination unit 9B performs the following detection based on the new icon ID included in the information. That is, the similarity determination unit 9B determines whether or not there is an icon 5 that is in a distant state in a positional relationship with the new icon and is similar to the new icon (hereinafter referred to as a "distant similar icon") when the new icon is arranged at the designated position. When the long-distance similar icon does not exist, the similarity determination unit 9B outputs information indicating that the long-distance similar icon does not exist to the icon position control unit 10B as a response to the similar long-distance determination request information. On the other hand, when the distant similar icon exists, the similarity determination unit 9B outputs an icon ID of the distant similar icon (hereinafter, referred to as "distant similar icon ID") to the icon position control unit 10B as a response to the similar distant determination request information.

When information indicating that the similar icon is not present at the distant position is input from the similarity determination unit 9B as a response to the similar distant position determination request information, the icon position control unit 10B determines the designated position as the final arrangement position of the new icon, and outputs the determined position to the overall control unit 7B as a response to the arrangement position determination request information.

On the other hand, when the long-distance similar icon ID is input as a response to the similar long-distance determination request information, the icon position control unit 10B executes the following processing. That is, the icon position control unit 10B changes the arrangement position of the updated icon so that the new icon and the distant similar icon are in a close state. Fig. 16 is a diagram showing an example of the home screen 4 of 2 pages. For example, in fig. 16, the arrangement point Q161 is set to be a designated position. In this case, when the existing icon 5 placed at the placement point Q162 is similar to the new icon, the icon position control unit 10B determines Q163 as the new placement position of the new icon. After changing the arrangement position of the new icon, the icon position control unit 10B notifies the collective control unit 7B of information indicating the arrangement position of the new icon after the change as a response to the arrangement position determination request information.

The above processing is position adjustment processing. As described above, in the position adjustment process, when the tendency detection unit 23 detects that the user has the 1 st tendency, the icon position control unit 10B separates the position of the new icon from the position of the icon similar to the new icon when the icon 5 similar to the new icon is arranged at the position having the relationship of the proximity state with the designated position of the new icon. On the other hand, when the trend detecting unit 23 detects that there is a trend 2, the icon position control unit 10B brings the position of the new icon close to the position of the icon similar to the new icon when the icon similar to the new icon is arranged at the position having a distant relationship with the designated position of the new icon.

When receiving a response indicating that the designated position is the final placement position or a response indicating that the designated position is the final placement position, the collective control unit 7B places a new icon at the designated position. On the other hand, when receiving a response to the information indicating the changed arrangement position of the new icon as the arrangement position determination request information, the overall control unit 7B arranges the new icon at the changed arrangement position. The overall control unit 7B updates the contents of the icon management list in response to a change in the arrangement position of the new icon and a change in the arrangement position of another icon accompanying the change in the arrangement position of the new icon.

As a result of the above processing, when the user tends to be 1 st, the new icon is arranged at a position where the similar icon 5 does not exist in the adjacent portion. Therefore, at the timing when a new icon is newly arranged on the home screen 4, it is possible to provide the home screen 4 in which erroneous selection of the icon 5 is less likely to occur for a user who has a tendency to erroneously select one icon as another icon when 2 icons similar to each other are in a neighboring state.

In addition, when the user has the tendency 2, the new icon is arranged in a position adjacent to the similar icon 5. Therefore, at the timing when a new icon is newly arranged on the home screen 4, it is possible to provide the home screen 4 in which erroneous selection of the icon 5 is less likely to occur for a user who has a tendency to erroneously select one icon as another icon when 2 icons similar to each other are in a neighboring state.

Next, an operation example of the mobile terminal 2B according to the present embodiment will be described with reference to a flowchart. The flowcharts FF in fig. 17 and 18 are flowcharts showing the operation of the mobile terminal 2B. As shown in the flowchart FF, when the user instructs the start of installation of a new application, the overall controller 7B outputs placement position determination request information including a new icon ID to the icon position controller 10B (step SF 1).

When the arrangement position determination request information is input (step SF2), the icon position control unit 10B inquires of the tendency detection unit 23B whether there is a1 st tendency or a2 nd tendency (step SF 3).

In response to the inquiry from the icon position control unit 10B, the tendency detection unit 23B responds to the icon position control unit 10B with either the meanings of "tendency 1", "tendency 2", or "the user does not have both tendency 1 and tendency 2" (step SF 4).

The icon position control unit 10B receives the response from the tendency detection unit 23B, and determines whether the user has the 1 st tendency, the 2 nd tendency, or neither the 1 st tendency nor the 2 nd tendency (step SF 5). When the user does not have both the 1 st tendency and the 2 nd tendency (step SF 5: "no tendency"), the icon position control unit 10B determines the designated position as the final arrangement position, and notifies the collective control unit 7B of the determined position as a response to the arrangement position determination request information (step SF 6). After the process at step SF6, the process proceeds to step SF 27.

On the other hand, when the user has the 1 st tendency (step SF 5: "tendency 1"), the icon position control unit 10B outputs the similarity determination request information including the new icon ID to the similarity determination unit 9B (step SF 7).

When the similar proximity determination request information is input (step SF8), the similarity determination unit 9B determines whether or not a proximity similar icon exists (step SF 9). When the proximity similar icon does not exist (no in step SF9), the similarity determination unit 9B outputs information indicating that the proximity similar icon does not exist to the icon position control unit 10B as a response to the proximity determination request information (step SF 10).

When information indicating that there is no similar icon is input from the similarity determination unit 9B (step SF11), the icon position control unit 10B determines the designated position as the final arrangement position of the new icon, and outputs the determined position to the overall control unit 7B as a response to the arrangement position determination request information (step SF 12). After the process at step SF12, the process proceeds to step SF 27.

On the other hand, when the proximity similar icon exists (yes in step SF9), the similarity determination unit 9B outputs the proximity similar icon ID to the icon position control unit 10B as a response to the similar proximity determination request information (step SF 13).

When the proximity similar icon ID is input (step SF14), the icon position control unit 10B updates the arrangement position of the icon so that the new icon is separated from the proximity similar icon (step SF 15). Next, the icon position control unit 10B notifies the collective control unit 7B of information indicating the position of the arrangement position of the new icon after the change, as a response to the arrangement position determination request information (step SF 16). After the process at step SF16, the process proceeds to step SF 27.

When the user has the tendency 2 in the determination at step SF5 (step SF 5: "tendency 2"), the icon position control unit 10B outputs the similar distance determination request information including the new icon ID to the similar determination unit 9B (step SF 17).

When the similar distance determination request information is input (step SF18), the similar determination unit 9B determines whether or not a remote similar icon exists (step SF 19). When the long-distance similar icon does not exist (no in step SF19), the similarity determination unit 9B outputs information indicating that the long-distance similar icon does not exist to the icon position control unit 10B as a response to the similar long-distance determination request information (step SF 20).

When information indicating that the distant similar icon does not exist is input (step SF21), the icon position control unit 10B determines the designated position as the final new icon arrangement position, and outputs the position to the collective control unit 7B as a response to the arrangement position determination request information (step SF 22). After the process at step SF22, the process proceeds to step SF 27.

On the other hand, when the long-distance similar icon is present in the determination at step SF19 (yes at step SF19), the similarity determination unit 9B outputs the long-distance similar icon ID to the icon position control unit 10B as a response to the similar long-distance determination request information (step SF 23).

When the long-distance similar icon ID is input as a response to the similar long-distance determination request information (step SF24), the icon position control unit 10B changes the arrangement position of the new icon so that the new icon and the long-distance similar icon are in a close state (step SF 25). Next, the icon position control unit 10B notifies the collective control unit 7B of information indicating the position of the arrangement position of the new icon after the change, as a response to the arrangement position determination request information (step SF 26). After the process at step SF26, the process proceeds to step SF 27. The process from step SF2 to step SF26 is a position adjustment process.

In step SF27, the overall control unit 7B arranges a new icon in accordance with the content of the response from the icon position control unit 10B. Specifically, the overall control unit 7B arranges the new icon at the designated position when receiving a response indicating that the designated position is the final arrangement position or a response indicating that the position is the arrangement position determination request information. On the other hand, when receiving a response to the information indicating the changed arrangement position of the new icon as the arrangement position determination request information, the overall control unit 7B arranges the new icon at the changed arrangement position.

< modification of embodiment 3 >

Next, a modification of embodiment 3 will be described. In embodiment 3 described above, the icon position control unit 10B performs the position changing process in the 3 rd mode. On the other hand, when the icon position control unit 10B performs the position change process in the 1 st embodiment, the mobile terminal 2B executes the following process.

That is, in the position adjustment processing, only the presence or absence of the 1 st tendency is determined by the tendency detection unit 23. Then, in the case where there is a tendency of 1 st, if there is a similar icon 5 in a portion where the positional relationship with the designated position of the new icon is in the adjacent state, the icon position control unit 10B changes and updates the arrangement position of the icons so that 2 icons 5 are separated by a distance.

According to the above modification, when the user tends to be 1 st, the new icon is arranged at a position where the similar icon 5 is not present in the adjacent portion. Therefore, it is possible to provide the home screen 4 in which erroneous selection of the icon 5 is less likely to occur for the user having the 1 st tendency.

As another modification, when the icon position control unit 10B performs the position change process in the 2 nd mode, the mobile terminal 2B executes the following process. That is, in the position adjustment processing, only the presence or absence of the 2 nd tendency is determined by the tendency detection unit 23. In the case of the 2 nd tendency, when the icon 5 similar to the icon 5 exists in the distant position in the positional relationship with the designated position of the new icon, the icon position control unit 10B changes the arrangement position of the new icon so that 2 icons 5 are in the adjacent state.

According to the above modification, when the user tends to be 2 nd, the new icon is arranged in a position adjacent to the similar icon 5. Therefore, it is possible to provide the home screen 4 in which erroneous selection of the icon 5 is less likely to occur for the user having the tendency of 2 nd.

While the embodiments 1 to 3 have been described above, the above embodiments are merely examples of the embodiment of the present invention, and the technical scope of the present invention is not to be construed as being limited thereto. That is, the present invention can be implemented in various forms without departing from the gist or main features thereof.

For example, in each of the above embodiments, the icon 5 is an object for starting an installed application. However, the icon 5 is not limited to the example in each embodiment. For example, the icon 5 may be an icon showing each selection item on a menu screen having a plurality of selection items.

Note that, in the above-described embodiments, the main screen 4 illustrated using the drawings is a very simplified drawing for convenience of explanation, and the form of the main screen 4 is not limited to the illustrated form.

In embodiment 1, when the function blocks of the display control apparatus 1 are executed, the display control apparatus 1 may be configured to execute a part or all of the above-described processing in cooperation with an external apparatus or by the external apparatus alone. In this case, the display control device 1 functions as a display control device in cooperation with an external device. As an example, a part or all of the processing of the similarity determination section 9 of the display control apparatus 1 may be executed by a cloud server that can communicate with the portable terminal 2 via a network.
