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

(Device configuration)
FIG. 1 is a block diagram showing the 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 has 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 content. The function of the clustering unit 12 can be implemented using, for example, a CPU (Central Processing Unit). The content can be content such as images and music, for example. Content information is stored in a storage device or the like as content information 11 . Here, each content has at least one attribute. For example, image content has attributes such as "shooting date and time" and "shooting location". Also, for example, music content has attributes such as "album", "artist", and "genre". The clustering unit 12 classifies the contents into clusters according to clustering conditions relating to at least part of such attributes possessed by the contents. The clustering unit 12 provides the display control unit 13 with information on clusters into which content is classified.

The display control unit 13 causes the display 14, which is a display device, to display a screen including content. The functions of the display control unit 13 can be realized using, for example, a CPU. The display 14 may be integrated with the information processing apparatus 10 as in the present embodiment, or may be separate. When the display 14 is separate from the information processing apparatus 10, the display control unit 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 content clustering result provided from 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 apparatus 10 as in the present embodiment, or may be separate. When the touch panel 15 and the information processing apparatus 10 are separate entities, 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 an operation signal provided from the touch panel 15 as a user's operation input. The functions of the operation acquisition unit 16 can be implemented using, for example, a CPU. The operation acquisition unit 16 acquires, for example, the number of contact positions, the movement of each contact position, and the like, regarding the contact detected by the touch panel 15 . Thereby, for example, user's operations such as touch, tap, drag, flick, and 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 acquired operation information to the display control unit 13 .

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

(Operation example)
In this embodiment, the clustering unit 12 classifies image content. First, according to the pinch operation acquired by the operation acquisition unit 16, the condition setting unit 17 newly sets the clustering condition “day” regarding the attribute “photographing date and time” of the image content, and the clustering unit 12 sets the clustering condition “day”. Classify image content into clusters. Furthermore, according to 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 date and time” of the image content.

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

(New setting of clustering conditions)
FIG. 2 is a diagram illustrating an example in which clustering conditions are 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 unsorted position to the cluster 120a to which it is sorted. In the figure, the process of this movement is indicated by (a) to (d).

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

In the present embodiment, the clustering condition with the finest granularity among the clustering conditions for the attribute “photographing date and time” is “day”. The condition setting unit 17 acquires the information of the user's pinch-out operation via the touch panel 15 and the operation acquisition unit 16, and in response to this operation, changes the clustering condition from the unset state to the clustering condition "day" with the finest granularity. Change to the set state. Accordingly, the clustering unit 12 classifies the content 110 into clusters 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 pinch-out operation opening amount d from the operation acquiring unit 16, and adjusts the distance from the position in (a) to (d) in proportion to the opening amount d. The content 110 is moved to the position of each cluster 120a in . This movement can also 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 if the opening amount d is equal to or greater than the threshold value, determines the setting of the clustering condition "day". At this time, the clustering unit 12 maintains the state in which the content 110 is classified into the cluster 120a with the clustering condition "day". In response to this, the display control unit 13 changes the display of the screen 100 to the state of (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, the condition setting unit 17 cancels the setting of the clustering condition "day". In other words, the condition setting unit 17 returns the clustering condition to an 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 (d), a cluster 120a into which the contents 110 are classified is displayed on the screen 100, and a position bar 130 is also displayed. A cluster 120a indicates a cluster into which the content 110 is classified, and may be displayed with names such as "6/2", "6/8", and "7/1". The position bar 130 is a display indicating 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 correspond to the entire time series in which the content is distributed, and may simply indicate the sense of scale of the cluster 120a.

As described above, in the present embodiment, a new clustering condition is set by the user's pinch-out operation. Although a case where a new clustering condition is set by a pinch-out operation has been described here, it is also possible to unset the clustering condition by a pinch-in operation.

(Change of clustering conditions)
FIG. 3 is a diagram showing an example of changing clustering conditions 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 classified by the clustering condition "day" to the position of the cluster 120b classified by the clustering condition "month". In the figure, the process of this movement is indicated 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 one month) using the same attribute “shooting date and time” of the content, and Contents each including location information (time) are classified into respective clusters. This predetermined length can be said to be the granularity of clustering using the attribute "shooting date and time". In other words, the clustering condition “day” and the clustering condition “month” classify the content into clusters by classifying the location information of the content with the first granularity on the time axis. ”, the first granularity is different.

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 similar to the state of (d) in FIG. Here, the user initiates a pinch-out operation on the lower right portion of screen 100 .

In the present embodiment, among the clustering conditions for the attribute "shooting date and time", the clustering condition that is one level coarser than "day" is "month". Therefore, the condition setting unit 17 that has acquired the information of the user's pinch-out operation changes the clustering condition from "day" to "month" according to this operation. Accordingly, 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) according to the pinch-out operation. For such a display, the display control unit 13 acquires information on the pinch-out operation opening amount d from the operation acquiring unit 16, and, in proportion to the opening amount d, shifts from the position of the cluster 120a in (a) to The content 110 is moved to the position of the cluster 120b in (c). This movement can also be said to be movement of the content 110 from the first position corresponding to the cluster 120a toward the second position corresponding to the cluster 120b.

By changing the clustering granularity 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 an animation in which the newly displayed content 110 enters the screen 100 together with an animation in which the already displayed content 110 moves. For example, the display control unit 13 causes the content 110 classified into the “August” cluster 120b in (c) to slide in from the lower end of the screen 100 in accordance with the pinch-out operation, as shown in (b). .

Furthermore, 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), in units of two months in (b), and in units of three months in (c).

Here, it is assumed that the pinch-out operation ends 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 greater than the threshold value, confirms the change to the clustering condition "month". At this time, the clustering unit 12 maintains the state in which the content 110 is classified into the cluster 120b with the clustering condition "month", and the display control unit 13 changes the display of the screen 100 to the state of (c). On the other hand, if the opening amount d is less than the threshold, 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 contents 110 are classified into the cluster 120b under the clustering condition "month", and restores the state in which the contents 110 are classified into the cluster 120a under the clustering condition "day". The control unit 13 returns the display of the screen 100 to the state of (a).

As described above, in this embodiment, the user's pinch-out operation changes the clustering condition. Although the case where the clustering granularity is coarsened by the pinch-out operation has been described here, it is also possible to make the clustering granularity finer by the pinch-in operation.

(Continuous change of clustering conditions)
FIG. 4 is a diagram showing an example of continuously changing clustering conditions in the first embodiment of the present disclosure. In the illustrated example, the clustering condition is changed from "month" to "quarter" and then to "year". At this time, on the screen 100, the content 110 moves from the position of the cluster 120b classified by the clustering condition "month", through the position of the cluster 120c classified by the clustering condition "quarter", to the clustering condition "year". Move to the position of the cluster 120d to be classified. In the figure, the process of this movement is indicated by (a) to (c).

In this embodiment, the granularity of clustering for the attribute "shooting date and time" becomes coarser as the clustering condition changes from "month" to "quarter" to "year". That is, the condition setting unit 17 that has acquired the user's pinch-out operation continuously changes the granularity of clustering to a coarser one 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 spread amount d exceeds the spread amount d1 at which the content 110 is displayed in the state of (b), the condition setting unit 17 confirms the change to the clustering condition "quarter", and further sets the clustering condition to Change to "Year". Also, 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).

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

As described above, in this embodiment, the clustering condition is continuously changed by the user's pinch-out operation. Here, the pinch-out operation is used to make the clustering granularity coarser, but it is also possible to make the clustering granularity finer by the pinch-in operation.

(Summary of this embodiment)
In the first embodiment of the present disclosure described above, as in the series of examples shown in FIGS. Gradually coarsen. In addition, by the user's pinch-in operation, the granularity of content clustering gradually becomes finer, and finally the content becomes unclassified. Such a change in clustering condition is displayed on the screen 100 as movement of the content 110 accompanying the user's pinch operation.

Such an operation and display makes it possible to easily adjust the granularity of clustering, for example, by an intuitive operation similar to enlarging and reducing a displayed image. In addition, 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" were exemplified as clustering conditions for "shooting date and time", but the present disclosure is not limited to this. For example, the clustering condition for "shooting date and time" may be set more finely, such as "30 minutes", "1 hour", "3 days", and "10 days". By finely setting the clustering conditions, for example, in continuously changing the clustering conditions as shown in FIG. 4, it is possible to change the granularity of clustering steplessly according to the pinch operation.

Further, in the above description, the user's pinch operation to the lower right portion of the screen 100 was exemplified as an operation acquired by the operation acquisition unit 16, but the present disclosure is not limited to this. For example, the user may perform a pinch operation at any position on the screen 100 , not just the lower right corner of the screen 100 . Further, the operation acquisition unit 16 may acquire a 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 user's pointing operation on the GUI such as the +/- buttons and slider bar displayed on the screen 100, and the condition setting unit 17 changes the clustering condition according to these operations. may

(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 differs from the above-described first embodiment in that the condition setting unit 17 uses "shooting position" instead of "shooting date and time" as the attribute of the image content. Other points are the same as those of the above-described first embodiment, so detailed description thereof will be omitted.

(Operation example)
In this embodiment, the clustering unit 12 classifies image content. First, according to 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. Classify image content into clusters. Furthermore, according to 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 "shooting position" in the present embodiment, that is, the geographical position information can be said to be geospatial position information. In clustering based on the clustering condition "district", the geographic space is divided into address areas (districts) of a predetermined hierarchy, and contents whose location information is included in each of the divided areas are classified into the same cluster. The address area is a preset area that hierarchically divides the geographic space. In this embodiment, the lowest layer is a "district" such as "Shibuya", the level one level above is a "prefecture" such as "Tokyo", and the level above that is a "country" such as "Japan". The granularity of clustering is changed by changing the hierarchy of the address area by using the address area in which the "" area is set.

FIG. 5 is a diagram showing an example of changing clustering conditions in the second embodiment of the present disclosure. In the illustrated example, the clustering condition is changed from "district" to "prefecture" and then to "country". At this time, on the screen 100, the content 110 moves from the position of the cluster 220a classified by the clustering condition "district" through the position of the cluster 220b classified by the clustering condition "prefecture" to the clustering condition "country". '' to the position of cluster 220c. In the figure, the process of this movement is indicated by (a) to (c).

In this embodiment, the granularity of clustering for the attribute "shooting position" becomes coarser as the clustering condition changes from "district" to "prefecture" to "country". That is, the condition setting unit 17 that has acquired the user's pinch-out operation continuously changes the granularity of clustering to a coarser one 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 described above. When the pinch-out operation ends during movement, it is determined whether to confirm or discard the change of the clustering conditions by comparing the pinch-out operation opening amount d with a predetermined threshold value.

As described above, in the present embodiment, the user's pinch-out operation sets and changes the clustering condition for the attribute "shooting position" in the same manner as the clustering condition for the attribute "shooting date and time" in the first embodiment. be done. Here, the pinch-out operation is used to make the clustering granularity coarser, but it is also possible to make the clustering granularity finer by the pinch-in operation.

(Summary of this embodiment)
In the second embodiment of the present disclosure described above, for example, as in the example shown in FIG. 5, the setting and changing of the clustering condition of the content according to the user's pinch operation changes the content attribute "shooting position". It also applies to clustering using In content classification using geospatial position information, it is possible to use a predetermined address area hierarchy as the granularity of clustering. As a result, the cluster ranges and names are closer to geographic names known to the user, and the clustering results are more likely to match the user's desires.

In the above description, "district", "prefecture", and "country" were exemplified as clustering conditions for "shooting position", but the present disclosure is not limited to this. For example, the clustering condition for "shooting position" may be set more finely, such as "building" or "block". By finely setting the clustering conditions, for example, in continuously changing the clustering conditions as shown in FIG. 5, it is possible to change the granularity of clustering steplessly according to the pinch operation.

Moreover, as the granularity of clustering, the hierarchy of the address regions does not necessarily have to be used as in the above example. For example, the clustering unit 12 may divide the geospace into grids to cluster the contents, and the condition setting unit 17 may change the size of the grids to change the granularity of clustering.

(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 differs from the above-described first embodiment in that the clustering unit 12 classifies music content and the condition setting unit 17 sets clustering conditions using different attributes of the content. do. Other points are the same as those of the above-described first embodiment, so detailed description thereof will be omitted.

(Operation example)
In this embodiment, the clustering unit 12 classifies music content. In the present embodiment, music content is classified and displayed in units of albums. 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 selects the music content with the clustering condition “artist”. Sort content into clusters. Furthermore, according to the pinch operation acquired by the operation acquiring unit 16, the condition setting unit 17 changes the clustering condition to a clustering condition related to another attribute "genre" of the music content.

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

FIG. 6 is a diagram showing an example of setting and changing clustering conditions 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". to the position of the cluster 320b classified by . In the figure, the process of this movement is indicated by (a) to (d).

Here, the content 310 is music content displayed in units of albums. In other words, 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 in units of albums is classified according to the attributes "artist" and "genre" of the music content. In this way, the clustering unit 12 and the display control unit 13 can also handle clusters obtained by classifying contents according to a certain clustering condition as contents when classifying them according to another clustering condition. The content 310 can be displayed on the screen 100, for example, as an icon that is a reduced album jacket image.

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

The condition setting unit 17 acquires the information of the user's pinch-out operation via the touch panel 15 and the operation acquisition unit 16. In response to this operation, the clustering condition is changed from the unset state to the clustering related to the attribute "artist" of the music content. Change to a state in which the condition "artist" is set. Accordingly, 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 classified into clusters 320a as shown in (b). Cluster 320a may be displayed with artist names "A," "B," and "C." In the state of (b), if the pinch-out operation is continued, the condition setting unit 17 confirms the change to the clustering condition "artist" and further changes the clustering condition to "genre". Also, 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 set independently, although they are related to some extent. In other words, even music content by the same artist may belong to different genres. For example, in (c), some content 310 moves from the "C" cluster 320a classified under the clustering condition "artist" toward the "Rock" cluster 320b under the clustering condition "genre", while the "pops" An example is shown in which there is also content 310 moving towards cluster 320b of "Techno" and there is also content 310 remaining to form cluster 320b of "Techno". By displaying the movement of the content 310 in this way, 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 shown in FIG. 6, the setting and change of the clustering condition of the content according to the user's pinch operation can be performed by the "artist" and " It is also applied during clustering using different attributes of content, such as "genre". This makes it possible to change attributes used for content clustering with a simple operation. Also, changes in clustering results due to changes in attributes can be visually grasped.

In the above description, "album", "artist", and "genre" are exemplified as attributes of music content, but the present disclosure is not limited to this. For example, attributes such as "composer" and "release 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. FIG.

In the fourth embodiment of the present disclosure, the operation acquisition unit 16 acquires a drag operation instead of a pinch operation by the user, and the display control unit 13 and the condition setting unit 17 acquire a single-touch drag operation and a multi-touch drag operation. It is different from the above-described first embodiment in that the process is switched depending on whether or not Other points are the same as those of the above-described first embodiment, so detailed description thereof will be omitted.

(Operation example)
FIG. 7 is a diagram illustrating an example of switching between clustering condition change and display scrolling in the fourth embodiment of the present disclosure.

In this embodiment, the clustering unit 12 classifies the image contents using the attribute "shooting date and time", as in the first embodiment. In the state of (a), similar to the example shown in FIG. 2(d), the contents 110 are classified into clusters 120a based on the clustering condition "day".

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

In (b), when the operation acquisition unit 16 acquires a single-touch drag operation, 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, while the cluster 120a from "6/2" to "7/1" is displayed in (b), the cluster 120a from "6/8" to "8/3" is displayed in (c). Cluster 120a is shown. In addition, the display control unit 13 moves the position displayed on the position bar 130 in accordance with this scrolling.

On the other hand, in (d), when the operation acquisition unit 16 acquires a multi-touch drag operation, 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”. Accordingly, 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). In addition, the display control unit 13 changes the display of the position bar 130 according to the change of classification.

In the figure, an example is shown in which an upward drag operation causes the display to scroll upward, or the granularity of clustering is coarsened. Similarly, a downward drag operation causes the display to scroll downward. , or finer granularity of clustering.

FIG. 8 is a flowchart showing processing of the information processing device 10 according to the fourth embodiment of the present disclosure. In order to simplify the explanation, the drawing shows the processing when the operation acquisition unit 16 acquires a drag operation in the vertical direction with respect to the screen 100 . In addition to the illustrated processing, processing when other types of operations or drag operations in other directions are acquired can 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 multiple contact positions, that is, multi-touch, or other, that is, single-touch. (step S101). Here, when it is determined that the drag operation is due to multi-touch, the clustering granularity change processing after step S103 is executed. On the other hand, if it is not determined that the drag operation is due to multi-touch, that is, if the drag operation is due to single-touch, the display scrolling process from step S113 onwards is executed.

In the clustering granularity change 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 directed 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 from "month" to "quarter". On the other hand, if it is not determined in step S103 that the drag operation is upward, that is, if the drag operation is downward, the condition setting unit 17 makes clustering finer (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 clusters the contents according to the provided condition (step S109). Next, the clustering unit 12 provides the clustering result 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. (step S111).

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

According to the present embodiment, the change of the clustering condition 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 examples shown in FIGS. 7 and 8, for the first and second movement operations in the same direction, to switch between changing the clustering conditions and scrolling the display.

As a result, for example, it is possible to change the granularity of clustering by performing a multi-touch drag operation in the same direction while enabling a display scroll operation by a single-touch drag operation. Since there is no need to display separate operation icons, the display of the GUI is simplified, and other types of operations such as flick operations and pinch operations can be assigned other operations.

In the above description, an example is described in which the display is scrolled by a single-touch drag operation in the vertical direction of the screen, and the granularity of clustering is changed by a multi-touch drag operation, but the present disclosure is limited to this. not something. For example, the display may be scrolled by a multi-touch drag operation in the vertical direction of the screen, and the granularity of clustering may be changed by a single-touch drag operation. Further, 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 or the like. Furthermore, a movement operation such as a flick operation may be used instead of the drag operation.

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

In the fifth embodiment of the present disclosure, the clustering unit 12 clusters the content using a plurality of attributes, and the condition setting unit 17 switches the processing depending on the direction of the pinch operation. is different from Other points are the same as those of the above-described first embodiment, so detailed description thereof will be omitted.

(Operation example)
9 to 11 are diagrams showing examples in which changes in clustering granularity for multiple attributes are switched in the fifth embodiment of the present disclosure.

In this embodiment, the clustering unit 12 classifies the image contents using the attribute "shooting date and 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 contents 110 are, for example, "content shot in Shibuya on 6/2", "content shot in Shinagawa on 6/2", and "content shot in Shibuya on 8/3". , clustered by content shot in the same district on the same day.

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

The display control unit 13 displays the result of clustering using the two pieces of position information on the display 14 as a screen 100 . On the screen 100, the clustering conditions related to the attribute "shooting date" are displayed on the horizontal axis, and the clustering conditions related to the attribute "shooting position" are displayed on the vertical axis, and each cluster 420a is represented by the coordinates of these two axes. be done. In other words, 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 a position bar 130 on the screen 100 . The position bar 130 is similar to the position bar 130 displayed in the first embodiment. , displayed horizontally.

FIG. 10 shows a state in which the operation acquisition unit 16 acquires a pinch operation in the horizontal direction with respect to the screen 100 in the state of FIG. 9 . At this time, the condition setting unit 17 changes the clustering condition for the attribute “shooting date and time” from “day” to “month”. Accordingly, the clustering unit 12 classifies the content 110 into clusters 420b generated based on the clustering condition "month, district". As a result, the contents 110 are displayed in the same month, for example, "content shot in Shibuya in June", "content shot in Shinagawa in June", and "content shot in Shibuya in August". are clustered for each content shot in the same area.

The display control unit 13 changes the display of the screen 100 according to this clustering result. Here, the classification of "district" on the vertical axis does not change, and the classification on the horizontal axis changes from "day" to "month". to form In addition, the display control unit 13 changes the display of the position bar 130 from monthly units to three-month units in accordance with changes in the clustering condition regarding the attribute “shooting date and time”.

FIG. 11 shows a state in which the operation acquisition unit 16 acquires a vertical pinch operation in the state of FIG. 9 . At this time, the condition setting unit 17 changes the clustering condition for the attribute "shooting position" from "district" to "prefecture". Accordingly, the clustering unit 12 classifies the content 110 into clusters 420c generated based on the clustering condition "day, prefecture". As a result, the contents 110 are, for example, "content shot in Tokyo on 6/2", "content shot in Saitama on 6/2", and "content shot in Tokyo on 6/8". , clustered by content shot in the same prefecture on the same day.

The display control unit 13 changes the display of the screen 100 according to this clustering result. Here, the classification of "day" on the horizontal axis does not change, and the classification on the vertical axis changes from "district" to "prefecture". 420c. The display control unit 13 does not change the display of the position bar 130 because the clustering condition for the attribute “shooting date and 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. In order to simplify the explanation, the drawing shows the processing when the pinch operation in the horizontal direction or the vertical direction of the screen 100 is acquired by the operation acquiring unit 16 . In addition to the illustrated processing, processing when other types of operations are acquired can be set separately.

First, the condition setting unit 17 determines whether or not the user's pinch operation acquired by the operation acquisition unit 16 is a pinch operation in the horizontal direction (step S201). Here, if it is determined that the pinch operation is a pinch operation in the horizontal direction, clustering granularity change processing for the attribute "shooting date and time" is executed in step S203 and thereafter. On the other hand, if the pinch operation is not determined to be a pinch operation in the horizontal direction, that is, if the pinch operation is a pinch operation in the vertical direction, clustering granularity change processing for the attribute "shooting position" is executed in step S209 and thereafter. .

In the clustering granularity change process for the attribute "shooting date and time", first, the condition setting unit 17 determines whether or not the pinch operation is pinch out (step S203). Here, when it is determined that the pinch operation is a pinch-out, the condition setting unit 17 coarsens the granularity of clustering by 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 from "month" to "quarter". On the other hand, if it is not determined that the pinch operation is pinch-out, that is, if the pinch operation is pinch-in, the condition setting unit 17 makes the granularity of clustering by the attribute "shooting date and time" finer (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 change processing for the attribute “shooting position”, first, the condition setting unit 17 determines whether or not the pinch operation is pinch out (step S209). Here, when it is determined that the pinch operation is a pinch-out, the condition setting unit 17 coarsens the granularity of clustering by the attribute "shooting position" (step S211). In this case, in the above example, the clustering condition is changed from "district" to "prefecture" and from "prefecture" to "country". On the other hand, if it is not determined that the pinch operation is pinch-out, that is, if the pinch operation is pinch-in, the condition setting unit 17 makes the granularity of clustering by the attribute "shooting position" finer (step S213). In this case, in the above example, the clustering condition is changed from "country" to "prefecture" and from "prefecture" to "district".

After the clustering granularity change processing for the attribute "shooting date and 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 clustering result 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. (step S217).

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

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

As a result, for example, when content is clustered using two types of attributes, the granularity of clustering can be changed by an intuitive operation for both attributes. At this time, if the direction in which the two types of attributes are expressed as positions is associated with the direction of the user's operation for changing the granularity of clustering by each attribute, it is possible to change the granularity of clustering by each attribute. Operation becomes more intuitive.

In the above description, an example in which the clustering granularity 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, a flick operation, or the like. Further, for example, when the granularity of clustering is changed by a drag operation, the present embodiment may be combined with the fourth embodiment. In this case, for example, the single-touch drag operation scrolls the display vertically or horizontally, and the multi-touch drag operation changes the clustering granularity for one of the two types of attributes.

The information processing apparatus according to any one of claims 1 to 17 . setting a clustering condition for classifying content into a predetermined cluster based on a user's pinch operation;
When changing the clustering condition from the first clustering condition to the second clustering condition based on the pinch- out operation, from the first position according to the first clustering condition to the second clustering condition controlling display of an animation in response to the pinch- out operation so as to move the display position of the content to a second position in response,
The process of setting the clustering condition includes determining the change of the clustering condition if the opening amount at the end of the pinch- out operation is equal to or greater than a threshold, and if the opening amount at the end of the pinch-out operation is less than the threshold cancels the modification of said clustering conditions,
A computer-implemented information processing method. setting a clustering condition for classifying content into a predetermined cluster based on a user's pinch operation;
When changing the clustering condition from the first clustering condition to the second clustering condition based on the pinch- out operation, from the first position according to the first clustering condition to the second clustering condition causing a computer to control display of an animation in response to said pinch- out operation so as to move the display position of said content to a corresponding second position;
The process of setting the clustering condition includes determining the change of the clustering condition if the opening amount at the end of the pinch- out operation is equal to or greater than a threshold, and if the opening amount at the end of the pinch-out operation is less than the threshold cancels the modification of said clustering conditions,
