(1. First embodiment)
First, a first embodiment of the present disclosure will be described with reference to FIGS. 1 to 4.

(Device configuration)
FIG. 1 is a block diagram showing a functional configuration of an information processing device 10 according to the first embodiment of the present disclosure. The information processing device 10 is a device such as a mobile phone or a PC (Personal Computer), and includes a clustering unit 12, a display control unit 13, a display 14, a touch panel 15, an operation acquisition unit 16, and a condition setting unit 17.

The clustering unit 12 clusters contents. The function of the clustering unit 12 can be realized by using, for example, a CPU (Central Processing Unit). The content may be content such as images and music. Content information is stored in the storage device or the like as content information 11. Here, each content has at least one attribute. For example, the image content has attributes such as “shooting date and time” and “shooting place”. Further, for example, the music content has attributes such as “album”, “artist”, and “genre”. The clustering unit 12 classifies the content into clusters according to the clustering conditions regarding at least a part of such attributes of the content. The clustering unit 12 provides the display control unit 13 with information on clusters into which the content is classified.

The display control unit 13 causes the display 14, which is a display device, to display a screen including the content. The function of the display control unit 13 can be realized by using a CPU, for example. The display 14 may be integrated with the information processing device 10 as in the present embodiment, or may be a separate body. When the display 14 is separate from the information processing device 10, the display controller 13 causes the display 14 to display an image via an interface such as a connection port. The display control unit 13 moves the position where the content is displayed on the screen according to the result of the content clustering provided by the clustering unit 12. Further, the display control unit 13 may acquire information on the user's operation from the operation acquisition unit 16 and change the display according to this operation. The image displayed on the display 14 by the display control unit 13 will be described later.

The touch panel 15 detects a touch on the display of the display 14 as a user's operation, and provides it as an operation signal to the operation acquisition unit 16. The touch panel 15 may be integrated with the information processing device 10 as in the present embodiment, or may be a separate body. When the touch panel 15 and the information processing device 10 are separate bodies, the touch panel 15 provides an operation signal to the operation acquisition unit 16 via an interface such as a connection port.

The operation acquisition unit 16 acquires the operation signal provided from the touch panel 15 as a user operation input. The function of the operation acquisition unit 16 can be realized by using a CPU, for example. The operation acquisition unit 16 acquires, for example, the number of contact positions and the movement of each contact position regarding the contact detected by the touch panel 15. Thereby, for example, a user's operation such as touch, tap, drag, flick, or pinch on the display of the display 14 can be acquired. The operation acquisition unit 16 provides the acquired operation information to the condition setting unit 17. The operation acquisition unit 16 may further provide the display control unit 13 with the acquired operation information.

The condition setting unit 17 changes the clustering condition for the clustering unit 12 to classify the content according to the user operation provided from the operation acquisition unit 16. The function of the condition setting unit 17 can be realized by using a CPU, for example. The setting of the clustering condition by the condition setting unit 17 may change the attribute of the content used for the clustering condition. Further, the condition setting unit 17 may newly set a clustering condition that has not been set until then. The setting of the clustering condition by the condition setting unit 17 will also be described later.

(Operation example)
In this embodiment, the clustering unit 12 classifies the image content. First, in accordance with the pinch operation acquired by the operation acquisition unit 16, the condition setting unit 17 newly sets the clustering condition “day” regarding the attribute “shooting date and time” of the image content, and the clustering unit 12 sets the clustering condition “day”. Classify image content into clusters. Further, in accordance with the pinch operation acquired by the operation acquisition unit 16, the condition setting unit 17 changes the clustering condition to another clustering condition regarding the same attribute “shooting date/time” of the image content.

Here, the attribute “imaging date and time”, that is, time information in the present embodiment can be said to be position information on the time axis. In the clustering based on the clustering condition “day”, the time axis is divided into a predetermined length (1 day), and the content in which the position information (time) is included in each of the divided sections is classified into the same cluster. Therefore, the content is classified into clusters (for example, “6/2”, “6/8”, “7/1”, etc.) corresponding to the day to which the shooting date/time belongs, according to the clustering condition “day”. In the present embodiment, the granularity of clustering is changed by changing the length of dividing the time axis.

(New setting of clustering condition)
FIG. 2 is a diagram showing an example in which a clustering condition is newly set in the first embodiment of the present disclosure. In the illustrated example, on the screen 100 displayed on the display 14, the content 110 moves from the position in the unclassified state to the position of the cluster 120a into which the content 110 is classified. In the figure, the process of this movement is shown by (a) to (d).

In the state of (a), the clustering condition is not set in the clustering unit 12. Therefore, the content 110 is displayed on the screen 100 as it is without being clustered. The content 110 can be displayed on the screen 100 as, for example, an icon in which an image is reduced. Here, the user starts a pinch operation for the display on the display 14. As illustrated, this pinch operation is a pinch out operation in the lower right portion of the screen 100.

In the present embodiment, of the clustering conditions related to the attribute “shooting date/time”, the clustering condition with the finest granularity is “day”. The condition setting unit 17, which has acquired the information of the user's pinch-out operation via the touch panel 15 and the operation acquisition unit 16, responds to this operation by setting the clustering condition “day” with the finest granularity from the state in which the clustering condition is not set. Change to the set state. According to this, the clustering unit 12 classifies the content 110 into the cluster 120a.

The content 110 displayed on the screen 100 moves from (a) to (b) and from (b) to (c) according to the pinch-out operation. For such a display, the display control unit 13 acquires information on the opening amount d of the pinch-out operation from the operation acquiring unit 16, and in proportion to the opening amount d, from the position in (a) to (d). The content 110 is moved to the position of each cluster 120a in FIG. This movement can be said to be movement from the first position where the unclustered content 110 was displayed to the second position corresponding to each cluster 120a.

Here, it is assumed that the pinch-out operation is completed in the state of (c). The condition setting unit 17 acquires information on the opening amount d at the end of the pinch-out operation from the operation acquisition unit 16. The condition setting unit 17 compares the opening amount d with a predetermined threshold value, and when the opening amount d is equal to or more than the threshold value, determines the setting of the clustering condition “day”. At this time, the clustering unit 12 holds the state in which the content 110 is classified into the cluster 120a under the clustering condition “day”. In response to this, the display control unit 13 changes the display of the screen 100 to the state (d).

On the other hand, when the pinch-out operation ends in the state of (c) and the opening amount d at the end of the pinch-out operation is less than the threshold value, the condition setting unit 17 cancels the setting of the clustering condition “day”. That is, the condition setting unit 17 returns the clustering condition to the unset state. At this time, the clustering unit 12 discards the state in which the content 110 is classified into the cluster 120a under the clustering condition “day”. In response to this, the display control unit 13 returns the display of the screen 100 to the state of (a).

In the state of (d), the cluster 120a into which the content 110 is classified is displayed on the screen 100, and the position bar 130 is further displayed. The cluster 120a indicates a cluster into which the content 110 is classified, and can be displayed with names such as "6/2", "6/8", and "7/1". The position bar 130 is a display showing the range of the displayed cluster 120a on the time axis. In the illustrated example, the position bar 130 is displayed in units of months. The position bar 130 does not necessarily have to correspond to the entire time series in which the contents are distributed, and may simply show the scale feeling of the cluster 120a.

As described above, in the present embodiment, the clustering condition is newly set by the pinch-out operation by the user. Note that, here, the case where the clustering condition is newly set by the pinch-out operation has been described, but similarly, the clustering condition can be set to the unset state by the pinch-in operation.

(Change clustering conditions)
FIG. 3 is a diagram illustrating an example in which the clustering condition is changed in the first embodiment of the present disclosure. In the illustrated example, the clustering condition is changed from “day” to “month”. At this time, on the screen 100, the content 110 moves from the position of the cluster 120a that is classified by the clustering condition “day” to the position of the cluster 120b that is also classified by the clustering condition “month”. In the figure, the process of this movement is shown by (a) to (c).

Here, the clustering conditions “day” and “month” are obtained by dividing the time axis by a predetermined length (one day or January) using the same attribute “shooting date” of the content. The contents, each of which includes position information (time), are classified into each cluster. This predetermined length can be said to be the granularity of clustering using the attribute “imaging date/time”. That is, the clustering condition “day” and the clustering condition “month” classify the content position information into the cluster by classifying the position information of the content with the first granularity on the time axis, and the clustering condition “day” and the clustering condition “month”. It can be said that the first granularity is different between "and".

In the state of (a), the clustering condition “day” is set in the clustering unit 12. On the screen 100, a cluster 120a and a position bar 130 are displayed. These displays are the same as in the state of FIG. Here, the user starts a pinch-out operation in the lower right part of the screen 100.

In the present embodiment, among the clustering conditions related to the attribute “photographing date and time”, the clustering condition having one-step granularity coarser than “day” is “month”. Therefore, the condition setting unit 17, which has acquired the information on the user's pinch-out operation, changes the clustering condition from “day” to “month” according to this operation. According to this, the clustering unit 12 changes the classification destination of the content 110 from the cluster 120a which is the first cluster to the cluster 120b which is the second cluster.

The content 110 displayed on the screen 100 gradually moves from (a) to (b) and from (b) to (c) in accordance with the pinch-out operation. For such a display, the display control unit 13 acquires information on the opening amount d of the pinch-out operation from the operation acquiring unit 16, and in proportion to the opening amount d, from the position of the cluster 120a in (a). The content 110 is moved to the position of the cluster 120b in (c). This movement can be said to be movement of the content 110 from the first position corresponding to the cluster 120a to the second position corresponding to the cluster 120b.

When the granularity of clustering is changed to a coarser one, the content 110 that was not displayed on the screen 100 before the change may be newly displayed after the change. In such a case, the display control unit 13 may display the animation in which the newly displayed content 110 enters the screen 100 together with the animation in which the already displayed content 110 moves. For example, the display control unit 13 slides in the content 110 classified into the “August” cluster 120b in (c) from the lower end of the screen 100 according to the pinch-out operation, as shown in (b). ..

Further, the display control unit 13 changes the display of the position bar 130 in proportion to the opening amount d. The position bar 130 is displayed in units of months in (a), but is displayed in units of 2 months in (b), and is displayed in units of 3 months in (c).

Here, it is assumed that the pinch-out operation is completed in the state of (b). The condition setting unit 17 acquires information on the opening amount d at the end of the pinch-out operation from the operation acquisition unit 16. The condition setting unit 17 compares the opening amount d with a predetermined threshold value, and when the opening amount d is equal to or larger than the threshold value, confirms the change to the clustering condition “month”. At this time, the clustering unit 12 holds the state where the content 110 is classified into the cluster 120b under the clustering condition “month”, and the display control unit 13 sets the display of the screen 100 to the state of (c). On the other hand, when the opening amount d is less than the threshold value, the condition setting unit 17 cancels the change to the clustering condition “month”. At this time, the clustering unit 12 discards the state in which the content 110 is classified into the cluster 120b under the clustering condition “month”, restores the state in which the content 110 is classified into the cluster 120a under the clustering condition “day”, and displays it. The control unit 13 returns the display of the screen 100 to the state of (a).

As described above, in the present embodiment, the clustering condition is changed by the pinch-out operation by the user. Here, the case where the granularity of clustering is coarsened by the pinch-out operation has been described, but similarly, the granularity of clustering can be made finer by the pinch-in operation.

(Continuous change of clustering conditions)
FIG. 4 is a diagram illustrating an example in which the clustering conditions are continuously changed in the first embodiment of the present disclosure. In the illustrated example, the clustering condition is changed from “month” to “quarter” and further to “year”. At this time, on the screen 100, the content 110 is in the clustering condition “year” from the position of the cluster 120b classified in the clustering condition “month” to the position of the cluster 120c similarly classified in the clustering condition “quarter”. Move to the position of the cluster 120d to be classified. In the figure, the process of this movement is shown by (a) to (c).

In the present embodiment, the granularity of clustering regarding the attribute “shooting date” becomes coarser as the clustering condition changes from “month” to “quarter” to “year”. In other words, the condition setting unit 17 that has acquired the user's pinch-out operation continuously changes the granularity of clustering to a coarser granularity in accordance with this operation. Accordingly, the classification destination of the content 110 is continuously changed from the cluster 120b to the cluster 120c and further to the cluster 120d.

The content 110 displayed on the screen 100 moves from (a) to (b) and from (b) to (c) according to the pinch-out operation. The change from (a) to (b) and the change from (b) to (c) are the same as the changes described with reference to FIG.

Here, the display control unit 13 and the condition setting unit 17 each acquire information on the opening amount d of the pinch-out operation from the operation acquisition unit 16. When the opening amount d becomes larger than the opening amount d1 in which the display of the content 110 is in the state of (b), the condition setting unit 17 confirms the change to the clustering condition “quarter” and further sets the clustering condition. Change to "year". In this case, the display control unit 13 further moves the display of the content 110 from the position of the cluster 120c, and moves the content 110 toward the cluster 120d shown in (c).

Further, the display control unit 13 changes the display of the position bar 130 according to the opening amount d, as in the example of FIG. The position bar 130 is displayed in units of 3 months in (a), but is displayed in units of 1 year in (b), and is displayed in units of 5 years in (c).

As described above, in the present embodiment, the clustering condition is continuously changed by the pinch-out operation by the user. Here, the case where the grain size of clustering is made coarser by the pinch-out operation has been described, but similarly, the grain size of clustering can be made finer by the pinch-in operation.

(Summary of this embodiment)
In the first embodiment of the present disclosure described above, contents are newly clustered by the user's pinch-out operation as in the series of examples illustrated in FIGS. Gradually coarser. Moreover, the granularity of the content clustering is gradually made finer by the user's pinch-in operation, and finally the content is in an unclassified state. Such a change in the clustering condition is displayed on the screen 100 as the movement of the content 110 due to the user's pinch operation.

With such an operation and display, the granularity of clustering can be easily adjusted by, for example, an intuitive operation similar to enlarging and reducing the displayed image. Further, it is possible to visually grasp the change in the granularity of clustering due to the operation.

In the above description, “day”, “month”, “quarter”, and “year” are illustrated as the clustering conditions related to “shooting date”, but the present disclosure is not limited to this. For example, the clustering condition relating to “shooting date/time” may be set in more detail such as “30 minutes”, “1 hour”, “3 days”, “10 days”. By finely setting the clustering conditions, it is possible to change the clustering granularity steplessly according to the pinch operation, for example, when the clustering conditions are continuously changed as in the example shown in FIG.

Further, in the above description, the user's pinch operation on the lower right portion of the screen 100 is illustrated as the operation acquired by the operation acquisition unit 16, but the present disclosure is not limited to this. For example, the user may perform the pinch operation not only at the lower right of the screen 100 but also at any position on the screen 100. Further, the operation acquisition unit 16 may acquire the user's drag or flick operation in a predetermined direction, and the condition setting unit 17 may change the clustering condition according to these operations. In addition, the operation acquisition unit 16 acquires the pointing operation of the user on the GUI such as the +/− button and the slider bar displayed on the screen 100, and the condition setting unit 17 changes the clustering condition according to these operations. May be.

(2. Second embodiment)
Next, a second embodiment of the present disclosure will be described with reference to FIG.

The second embodiment of the present disclosure is different from the above-described first embodiment in that the condition setting unit 17 uses “shooting position” instead of “shooting date/time” as an attribute of image content. Since the other points are the same as those of the first embodiment, detailed description thereof will be omitted.

(Operation example)
In this embodiment, the clustering unit 12 classifies the image content. First, in accordance with the pinch operation acquired by the operation acquisition unit 16, the condition setting unit 17 newly sets the clustering condition “district” regarding the attribute “shooting position” of the image content, and the clustering unit 12 sets the clustering condition “district”. Classify image content into clusters. Further, in accordance with the pinch operation acquired by the operation acquisition unit 16, the condition setting unit 17 changes the clustering condition to another clustering condition related to the same attribute “shooting position” of the image content.

Here, the attribute “imaging position” in the present embodiment, that is, information on a geographical position can be said to be position information in the geographic space. In the clustering based on the clustering condition “district”, the geographic space is divided into address areas (districts) of a predetermined hierarchy, and the content including the position information in each of the divided areas is classified into the same cluster. The address area is a preset area that hierarchically divides the geographic space. In the present embodiment, the lowest layer is a “district” such as “Shibuya”, the upper layer is a “prefecture” such as “Tokyo”, and the upper layer is a “country” such as “Japan”. The granularity of clustering is changed by changing the hierarchy of the address area using the address area in which the area "" is set.

FIG. 5 is a diagram illustrating an example in which the clustering condition is changed in the second embodiment of the present disclosure. In the illustrated example, the clustering condition is changed from “district” to “prefecture” and further to “country”. At this time, on the screen 100, the content 110 passes from the position of the cluster 220a classified by the clustering condition “district” to the position of the cluster 220b similarly classified by the clustering condition “prefecture” to the clustering condition “country”. It moves to the position of the cluster 220c classified by ". In the figure, the process of this movement is shown by (a) to (c).

In the present embodiment, the clustering granularity regarding the attribute “imaging position” becomes coarser as the clustering condition changes from “district” to “prefecture” to “country”. In other words, the condition setting unit 17 that has acquired the user's pinch-out operation continuously changes the granularity of clustering to a coarser granularity in accordance with this operation. Accordingly, the classification destination of the content 110 is continuously changed from the cluster 220a to the cluster 220b and further to the cluster 220c.

The content 110 displayed on the screen 100 moves from (a) to (b) and from (b) to (c) according to the pinch-out operation. Although not shown, the moving content 110 is also displayed as in the first embodiment. When the pinch-out operation is completed during the movement, the opening amount d of the pinch-out operation is compared with a predetermined threshold to determine whether to confirm or discard the change in the clustering condition.

As described above, in the present embodiment, the clustering condition for the attribute “shooting position” is set and changed by the user's pinch-out operation in the same manner as the clustering condition for the attribute “shooting date” in the first embodiment. To be done. Here, the case where the grain size of clustering is made coarser by the pinch-out operation has been described, but similarly, the grain size of clustering can be made finer by the pinch-in operation.

(Summary of this embodiment)
In the second embodiment of the present disclosure described above, setting and changing the content clustering condition according to the user's pinch operation changes the content attribute “shooting position” as in the example illustrated in FIG. 5, for example. It also applies to the clustering used. In classification of contents using position information in geospatial space, it is possible to use a hierarchy of a predetermined address area as a granularity of clustering. As a result, the range and name of the cluster become close to the geographical name known to the user, and the result of clustering easily matches the user's desire.

Note that, in the above description, “district”, “prefecture”, and “country” are exemplified as the clustering conditions regarding “imaging position”, but the present disclosure is not limited to this. For example, the clustering condition regarding “imaging position” may be set in more detail such as “building” or “block”. By finely setting the clustering condition, for example, in the continuous change of the clustering condition as in the example shown in FIG. 5, the granularity of clustering can be continuously changed according to the pinch operation.

Moreover, as the granularity of clustering, the hierarchy of the address area does not necessarily have to be used as in the above example. For example, the clustering unit 12 may cluster the content by dividing the geographic space into grids, and the condition setting unit 17 may change the size of the grid to change the clustering granularity.

(3. Third embodiment)
Next, a third embodiment of the present disclosure will be described with reference to FIG.

The third embodiment of the present disclosure is different from the above-described first embodiment in that the clustering unit 12 classifies the music content and the condition setting unit 17 sets the clustering condition using different attributes of the content. To do. Since the other points are the same as those of the first embodiment, detailed description thereof will be omitted.

(Operation example)
In the present embodiment, the clustering unit 12 classifies the music content. In the present embodiment, the music content is classified and displayed in album units. First, in accordance with the pinch operation acquired by the operation acquisition unit 16, the condition setting unit 17 newly sets the clustering condition “artist” regarding the attribute “artist” of the music content, and the clustering unit 12 sets the music under the clustering condition “artist”. Classify content into clusters. Further, in accordance with the pinch operation acquired by the operation acquisition unit 16, the condition setting unit 17 changes the clustering condition to a clustering condition regarding another attribute “genre” of the music content.

Here, the attributes "artist" and "genre" in the present embodiment are not position information, unlike the first and second embodiments described above. These attributes are the names of artists or genres. Therefore, when contents are clustered by these attributes, contents having the same artist name or the same genre name as an attribute are classified into the same cluster.

FIG. 6 is a diagram showing an example in which clustering conditions are set and changed in the third embodiment of the present disclosure. In the illustrated example, on the screen 100, the content 310 moves from the position in the unclassified state to the position of the cluster 320a classified by the clustering condition “artist”, and further, the clustering condition “genre”. It moves to the position of the cluster 320b classified by. In the figure, the process of this movement is shown by (a) to (d).

Here, the content 310 is music content displayed in album units. That is, the content 310 can be said to be a cluster in which music content is classified by the attribute “album”. In the present embodiment, the content 310 for each album is classified by the attribute “artist” and “genre” of the music content. In this way, the clustering unit 12 and the display control unit 13 can treat a cluster obtained by classifying content according to a certain clustering condition as content when classifying the cluster under another clustering condition. The content 310 can be displayed on the screen 100 as, for example, an icon obtained by reducing the jacket image of the album.

In the state of (a), the clustering condition is not set in the clustering unit 12 for the music content in album units. Therefore, the content 310 is displayed on the screen 100 as it is without being clustered. Here, the user starts a pinch operation for the display on the display 14. As illustrated, this pinch operation is a pinch out operation in the lower right portion of the screen 100.

The condition setting unit 17, which has acquired the information of the user's pinch-out operation via the touch panel 15 and the operation acquisition unit 16, responds to this operation from the state in which the clustering condition is not set to the clustering related to the attribute “artist” of the music content. Change the condition to "Artist". According to this, the clustering unit 12 classifies the content 310 into clusters 320a for each attribute “artist”.

The content 310 displayed on the screen 100 moves according to the pinch-out operation, and is in a state of being classified into the cluster 320a as shown in (b). The cluster 320a can be displayed with artist names "A", "B", "C". When the pinch-out operation is further continued in the state of (b), the condition setting unit 17 confirms the change to the clustering condition “artist” and further changes the clustering condition to “genre”. In this case, the display control unit 13 further changes the display of the content 110 from the state classified into the cluster 320a, and moves the content 110 toward the cluster 320b shown in (d).

Here, the attributes "artist" and "genre" are attributes that are independently set, although they are related to some extent. In other words, the music content of the same artist may belong to different genres. For example, in (c), if there is content 310 that moves from the cluster 320a of "C" classified by the clustering condition "artist" to the cluster 320b of "Rock" by the clustering condition "genre", there is "Pops". There is also an example in which some content 310 moves towards cluster 320 b of “Techno” and some content 310 remains to form cluster 320 b of “Techno”. By displaying such movement of the content 310, it becomes easier to understand the relationship of the content between different attributes.

(Summary of this embodiment)
In the third embodiment of the present disclosure described above, for example, as in the example illustrated in FIG. 6, the setting and change of the content clustering condition according to the user's pinch operation can be performed by changing the “artist” and the “artist” of the music content. It is also applied during clustering using different attributes of content, such as "genre". This makes it possible to change the attributes used for content clustering with a simple operation. Further, it is possible to visually grasp the change in the clustering result due to the change of the attribute.

In the above description, “album”, “artist”, and “genre” are illustrated as the attributes of the music content, but the present disclosure is not limited to this. For example, attributes such as “composer” and “announcement year” may be used for classification.

(4. Fourth Embodiment)
Next, a fourth embodiment of the present disclosure will be described with reference to FIGS. 7 and 8.

In the fourth embodiment of the present disclosure, the operation acquisition unit 16 acquires a drag operation instead of the user's pinch operation, and the display control unit 13 and the condition setting unit 17 determine that the drag operation is a single touch or multi-touch. This is different from the first embodiment in that the processing is switched depending on the case. Since the other points are the same as those of the first embodiment, detailed description thereof will be omitted.

(Operation example)
FIG. 7 is a diagram illustrating an example in which changing of clustering conditions and scrolling of display are switched in the fourth embodiment of the present disclosure.

In the present embodiment, the clustering unit 12 classifies the image contents by using the attribute “shooting date/time” as in the first embodiment. In the state of (a), the content 110 is classified into the cluster 120a based on the clustering condition “day”, as in the example shown in FIG. 2(d).

From here, the display of the screen 100 changes in two ways depending on the type of user operation acquired by the operation acquisition unit 16. One is a case where a drag operation by a single touch is acquired by the operation acquisition unit 16, and is shown as (b) and (c). The other is a case where a drag operation by multi-touch is acquired by the operation acquisition unit 16 and is shown as (d) and (e). Here, it can be said that the drag operation by multi-touch and the drag operation by single-touch are the first and second movement operations by the user.

In (b), when the operation acquisition unit 16 acquires a drag operation by single touch, the condition setting unit 17 does not change the content clustering condition. On the other hand, the display control unit 13 scrolls the display of the content 110 and the cluster 120a according to the drag operation. As a result, in (c), the display of the screen 100 is scrolled without changing the classification of the content 110 into the cluster 120a. Specifically, in (b), the clusters 120a from “6/2” to “7/1” were displayed, whereas in (c), the clusters from “6/8” to “8/3” were displayed. The cluster 120a is displayed. Further, the display control unit 13 moves the position displayed on the position bar 130 in accordance with this scroll.

On the other hand, in (d), when the operation acquisition unit 16 acquires a drag operation by multi-touch, the condition setting unit 17 changes the content clustering condition. Specifically, the condition setting unit 17 changes the content clustering condition from “day” to “month”. According to this, the display control unit 13 moves the content 110 from the position of the cluster 120a in (d) to the position of the cluster 120b in (e). Further, the display control unit 13 changes the display of the position bar 130 according to the change of the classification.

In the figure, an example in which the display is scrolled upward by the upward drag operation or the granularity of clustering is coarse is shown, but similarly, the display is scrolled downward by the downward drag operation. , Or clustering can be made finer.

FIG. 8 is a flowchart showing processing of the information processing device 10 according to the fourth embodiment of the present disclosure. Note that, in order to simplify the description, the figure shows the processing when the operation acquisition unit 16 acquires a vertical drag operation with respect to the screen 100. In addition to the illustrated processing, processing when another type of operation or a drag operation in another direction is acquired may be set separately.

First, the display control unit 13 and the condition setting unit 17 determine whether the user's drag operation acquired by the operation acquisition unit 16 has a plurality of contact positions, that is, multi-touch, or other, that is, a single touch. Yes (step S101). Here, when it is determined that the drag operation is a multi-touch operation, the clustering granularity changing process of step S103 and subsequent steps is executed. On the other hand, if it is not determined that the drag operation is multi-touch, that is, if the drag operation is single-touch, the scrolling process of the display in step S113 and the subsequent steps is executed.

In the clustering granularity changing process, first, the condition setting unit 17 determines whether or not the drag operation is upward (step S103). Here, when it is determined that the drag operation is upward, the condition setting unit 17 coarsens the granularity of clustering (step S105). In this case, in the above example, the clustering condition is changed from “day” to “month”, or “month” to “quarter”. On the other hand, when it is not determined in step S103 that the drag operation is upward, that is, when the drag operation is downward, the condition setting unit 17 makes the granularity of clustering fine (step S107). In this case, in the above example, the clustering condition is changed from “quarter” to “month” or from “month” to “day”.

Next, the condition setting unit 17 provides the clustering condition changed in step S105 or step S107 to the clustering unit 12, and the clustering unit 12 executes the content clustering under the provided condition (step S109). Next, the clustering unit 12 provides the result of clustering to the display control unit 13, and the display control unit 13 causes the content 110 to move toward the new cluster 120 on the screen 100 as in the above example. The display is changed to (step S111).

On the other hand, in the display scroll process, first, the display control unit 13 determines whether the drag operation is upward (step S113). Here, when it is determined that the drag operation is upward, the display control unit 13 scrolls the display upward (step S115). On the other hand, when it is not determined that the drag operation is upward, that is, when the drag operation is downward, the display control unit 13 scrolls the display downward (step S117).

According to the present embodiment, the clustering condition change and the scroll operation are switched by the above processing.

(Summary of this embodiment)
In the fourth embodiment of the present disclosure described above, for example, as in the example illustrated in FIGS. 7 and 8, the first and second movement operations in the same direction are changed depending on the type of movement operation. Switch between changing the clustering condition and scrolling the display.

Thereby, for example, it is possible to change the clustering granularity by the drag operation by the multi-touch in the same direction while enabling the scroll operation of the display by the drag operation by the single touch. Since it is not necessary to display a separate operation icon, the GUI can be displayed easily, and other operations can be assigned to other types of operations such as flick operation and pinch operation.

In the above description, an example in which the display is scrolled by a drag operation with a single touch in the vertical direction of the screen and the granularity of clustering is changed by a drag operation with a multi touch has been described, but the present disclosure is not limited to this. Not something. For example, the display may be scrolled by a drag operation by multi-touch in the vertical direction of the screen, and the granularity of clustering may be changed by the drag operation by a single touch. The direction of the drag operation is not limited to the vertical direction with respect to the screen 100, and may be the horizontal direction. Furthermore, instead of the drag operation, a moving operation such as a flick operation may be used.

(5. Fifth Embodiment)
Next, a fifth embodiment of the present disclosure will be described with reference to FIGS. 9 to 12.

The fifth embodiment of the present disclosure is that the clustering unit 12 clusters contents using a plurality of attributes, and the condition setting unit 17 switches processing depending on a direction of a pinch operation, in the first embodiment described above. Is different from. Since the other points are the same as those of the first embodiment, detailed description thereof will be omitted.

(Operation example)
9 to 11 are diagrams illustrating an example in which changing of clustering granularity in a plurality of attributes is switched in the fifth embodiment of the present disclosure.

In the present embodiment, the clustering unit 12 classifies the image content using the attribute “shooting date/time” and the attribute “shooting position”. For example, as shown in FIG. 9, the clustering unit 12 classifies the content 110 into clusters 420a generated based on the clustering condition “day, district”. As a result, the content 110 is, for example, "content shot in Shibuya on June 2nd", "content shot in Shinagawa on June 2nd", "content shot in Shibuya on August 3rd", and so on. , Clustered by content shot in the same district on the same day.

Here, the attributes “shooting date and time” and “shooting position” in the present embodiment are position information on the time axis and on the geospatial space, respectively, and can be said to be first and second position information. As described in the first embodiment, in clustering using position information on the time axis, the granularity of clustering changes by changing the length of division of the time axis. Further, as described in the second embodiment, in clustering using position information in geospatial space, the granularity of clustering changes by changing the hierarchy of the address area used for clustering. In this way, the granularity of clustering can be changed for each of the first and second position information used in this embodiment. In the present embodiment, which clustering granularity is changed among the first or second position information is switched according to the direction of the user's operation.

The display control unit 13 displays the result of clustering using the above two pieces of position information on the display 14 as a screen 100. In the screen 100, clustering conditions regarding the attribute “shooting date and time” are displayed on the horizontal axis, and clustering conditions regarding the attribute “shooting position” are displayed on the vertical axis, and each cluster 420a is represented by the coordinates of these two axes. To be done. That is, the cluster 420a whose horizontal axis is "6/2" and whose vertical axis is "Shibuya" is "content shot in Shibuya on 6/2". The display control unit 13 may further display the position bar 130 on the screen 100. The position bar 130 is similar to the position bar 130 displayed in the first embodiment or the like, but in the present embodiment, the clustering condition regarding the attribute “imaging date/time” is expressed on the horizontal axis. , Displayed in the horizontal direction.

FIG. 10 shows a state in which the operation acquisition unit 16 has acquired a lateral pinch operation with respect to the screen 100 in the state of FIG. At this time, the condition setting unit 17 changes the clustering condition relating to the attribute “shooting date/time” from “day” to “month”. According to this, the clustering unit 12 classifies the content 110 into clusters 420b generated based on the clustering condition “month, district”. As a result, the content 110 is the same month, for example, "content shot in Shibuya in June", "content shot in Shinagawa in June", and "content shot in Shibuya in August". It is clustered for each content shot in the same area.

The display control unit 13 changes the display of the screen 100 according to the clustering result. Here, since the classification of “districts” in the vertical axis does not change and the classification of the horizontal axis changes from “day” to “month”, each cluster 420a converges in the horizontal direction and clusters 420b. To form. Further, the display control unit 13 changes the display of the position bar 130 from the monthly unit to the three-month unit in accordance with the change of the clustering condition regarding the attribute “imaging date/time”.

FIG. 11 shows a state in which the operation acquisition unit 16 has acquired a vertical pinch operation in the state of FIG. At this time, the condition setting unit 17 changes the clustering condition for the attribute “imaging position” from “district” to “prefecture”. According to this, the clustering unit 12 classifies the content 110 into clusters 420c generated based on the clustering condition "day, prefecture". As a result, the content 110 is, for example, "content shot in Tokyo on June 2nd", "content shot in Saitama on June 2nd", or "content shot in Tokyo on June 8th". , Clustered for each content shot in the same prefecture on the same day.

The display control unit 13 changes the display of the screen 100 according to the clustering result. Here, the classification of “day” on the horizontal axis does not change, and the classification of the vertical axis changes from “district” to “prefecture”, so that each cluster 420a converges in the vertical direction. 420c is formed. The display control unit 13 does not change the display of the position bar 130 because the clustering condition related to the attribute “shooting date/time” does not change.

FIG. 12 is a flowchart showing processing of the information processing device 10 according to the fifth embodiment of the present disclosure. Note that, in order to simplify the description, the drawing shows the processing when the operation acquisition unit 16 acquires a pinch operation in the horizontal direction or the vertical direction of the screen 100. In addition to the illustrated processing, processing when another type of operation is acquired may be set separately.

First, the condition setting unit 17 determines whether the user's pinch operation acquired by the operation acquisition unit 16 is a horizontal pinch operation (step S201). Here, when it is determined that the pinch operation is the horizontal pinch operation, the clustering granularity changing process of the attribute “imaging date and time” after step S203 is executed. On the other hand, when it is not determined that the pinch operation is the horizontal pinch operation, that is, when the pinch operation is the vertical pinch operation, the clustering granularity changing process of the attribute “imaging position” after step S209 is executed. ..

In the clustering granularity changing process of the attribute “imaging date/time”, the condition setting unit 17 first determines whether the pinch operation is pinch out (step S203). Here, when it is determined that the pinch operation is pinch out, the condition setting unit 17 coarsens the granularity of clustering according to the attribute “shooting date and time” (step S205). In this case, in the above example, the clustering condition is changed from “day” to “month”, or “month” to “quarter”. On the other hand, when it is not determined that the pinch operation is the pinch out, that is, when the pinch operation is the pinch in, the condition setting unit 17 makes the clustering granularity based on the attribute “shooting date and time” fine (step S207). In this case, in the above example, the clustering condition is changed from “quarter” to “month” or from “month” to “day”.

In the clustering granularity changing process of the attribute “imaging position”, the condition setting unit 17 first determines whether or not the pinch operation is pinch out (step S209). Here, when it is determined that the pinch operation is the pinch out, the condition setting unit 17 coarsens the granularity of clustering according to the attribute “imaging position” (step S211). In this case, in the above example, the clustering condition is changed from “district” to “prefecture”, “prefecture” to “country”, and so on. On the other hand, when it is not determined that the pinch operation is pinch out, that is, when the pinch operation is pinch in, the condition setting unit 17 makes the clustering granularity based on the attribute “imaging position” fine (step S213). In this case, in the above example, the clustering condition is changed from “country” to “prefecture”, “prefecture” to “district”, and so on.

After the clustering granularity changing process of the attribute “shooting date/time” or “shooting position”, the condition setting unit 17 provides the changed clustering condition to the clustering unit 12, and the clustering unit 12 clusters the content under the provided condition. Is executed (step S215). Next, the clustering unit 12 provides the result of clustering to the display control unit 13, and the display control unit 13 causes the content 110 to move toward the new cluster 420 on the screen 100 as in the above example. The display is changed to (step S217).

According to the present embodiment, the clustering granularity change in a plurality of attributes is switched by the above-described processing.

(Summary of this embodiment)
In the fifth embodiment of the present disclosure described above, for example, as in the examples illustrated in FIGS. 9 to 12, the clustering granularity change in a plurality of attributes is switched depending on the direction of the user's operation.

Thereby, for example, when the content is clustered using two types of attributes, the granularity of clustering can be changed for any of the attributes by an intuitive operation. At this time, if the direction in which the two types of attributes are expressed as a position and the direction of the user operation for changing the granularity of clustering according to each attribute are made to correspond to each other, the granularity of clustering due to each attribute can be changed The operation becomes more intuitive.

In the above description, an example in which the granularity of clustering is changed by a pinch operation has been described, but the present disclosure is not limited to this. For example, the granularity of clustering may be changed by a drag operation or a flick operation. Further, for example, when the granularity of clustering is changed by a drag operation, this embodiment may be combined with the above-mentioned fourth embodiment. In this case, for example, a single-touch drag operation scrolls the display vertically or horizontally, and a multi-touch drag operation changes the clustering granularity for one of two types of attributes.
