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

(Device configuration)
FIG. 1 is a block diagram illustrating a functional configuration of the information processing apparatus 10 according to the first embodiment of the present disclosure. The information processing apparatus 10 is an apparatus such as a mobile phone or a PC (Personal Computer), for example, 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 content. The function of the clustering unit 12 can be realized using, for example, a CPU (Central Processing Unit). The content can be content such as an image or music. Content information is stored as content information 11 in a storage device or the like. Here, each content has at least one attribute. For example, the image content has attributes such as “shooting date” and “shooting location”. 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 a clustering condition regarding at least a part of such attributes of the content. The clustering unit 12 provides the display control unit 13 with information on the cluster into which the content is classified.

  The display control unit 13 displays a screen including content on the display 14 that is a display device. The function 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 a separate body. When the display 14 is separate from the information processing apparatus 10, the display control unit 13 displays an image on the display 14 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 from the clustering unit 12. Further, the display control unit 13 may acquire user operation information from the operation acquisition unit 16 and change the display according to the 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 14 as a user operation, and provides the operation acquisition unit 16 with the operation signal. The touch panel 15 may be integrated with the information processing apparatus 10 as in the present embodiment, or may be a separate body. When the touch panel 15 and the information processing apparatus 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 an operation signal provided from the touch panel 15 as a user operation input. The function of the operation acquisition unit 16 can be realized using, for example, a CPU. For the contact detected by the touch panel 15, the operation acquisition unit 16 acquires, for example, the number of contact positions and the movement of each contact position. Thereby, for example, operations such as a user's touch, tap, drag, flick, and pinch on 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 control information to the display control unit 13.

  The condition setting unit 17 changes the clustering condition for the clustering unit 12 to classify the content in accordance with the user operation provided from the operation acquisition unit 16. The function of the condition setting unit 17 can be realized 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 so far. The setting of clustering conditions by the condition setting unit 17 will also be described later.

(Operation example)
In the present 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 “shooting date” of the image content, and the clustering unit 12 sets the clustering condition “day”. Classify image content into clusters. Further, 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” of the image content.

  Here, the attribute “shooting date and time” in this embodiment, that is, 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 (one day), and contents including position information (time) in each of the divided sections are classified into the same cluster. Therefore, the content is classified into clusters corresponding to the date to which the shooting date and time belongs (for example, “6/2”, “6/8”, “7/1”, etc.) 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 illustrating an example in which the 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 each is classified. In the figure, this movement process is indicated by (a) to (d).

  In the state (a), no clustering condition is 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 an icon obtained by reducing an image, for example. Here, the user starts a pinch operation for the display 14. As shown in the figure, this pinch operation is a pinch out operation at the lower right portion of the screen 100.

  In the present embodiment, among the clustering conditions related to the attribute “shooting date and time”, the clustering condition with the finest granularity is “day”. In response to this operation, the condition setting unit 17 that has acquired information on the user's pinch-out operation via the touch panel 15 and the operation acquisition unit 16 determines that the clustering condition “day” with the finest granularity from the state in which the clustering condition is not set. Change to the set state. Accordingly, 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 display, the display control unit 13 acquires information on the opening amount d of the pinch-out operation from the operation acquisition unit 16, and in proportion to the opening amount d, from the position in (a) (d). The content 110 is moved to the position of each cluster 120a. This movement can be said to be a movement from the first position where the non-clustered content 110 is displayed toward 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 about 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, the setting of the clustering condition “day” is confirmed. At this time, the clustering unit 12 holds a 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 is completed 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 an unset state. At this time, the clustering unit 12 discards 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 returns the display of the screen 100 to the state of (a).

  In the state (d), the cluster 120a in 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 on the time axis of the displayed cluster 120a. 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 scale feeling of the cluster 120a.

  As described above, in this embodiment, the clustering condition is newly set by the user's pinch-out operation. Although the case where the clustering condition is newly set by the pinch-out operation has been described here, the clustering condition can be set to the unset state by the pinch-in operation similarly to this.

(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 each classified by the clustering condition “day” to the position of the cluster 120b similarly classified by the clustering condition “month”. In the figure, this movement process 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. The contents each including position information (time) are classified into respective clusters. This predetermined length can be said to be the granularity of clustering using the attribute “shooting date”. In other words, the clustering condition “day” and the clustering condition “month” classify the content into clusters 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 from

  In the state (a), the clustering unit 12 is set with the clustering condition “day”. 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 at the lower right portion of the screen 100.

  In the present embodiment, among the clustering conditions related to the attribute “shooting date and time”, the clustering condition whose granularity is one step 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 that is the first cluster to the cluster 120b that 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 display, the display control unit 13 acquires information on the opening amount d of the pinch-out operation from the operation acquisition 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 also be said to be a movement of the content 110 from the first position corresponding to the cluster 120a toward the second position corresponding to the cluster 120b.

  When the clustering granularity 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 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 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 about 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, the change to the clustering condition “month” is confirmed. At this time, the clustering unit 12 holds the state in which 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 where the content 110 is classified into the cluster 120b with the clustering condition “month”, and restores the state where the content 110 is classified into the cluster 120a with 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 clustering condition is changed by the user's pinch-out operation. Although the case where the clustering granularity is coarsened by the pinch-out operation has been described here, the clustering granularity can also 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 condition is 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 contents 110 are moved from the position of the cluster 120b classified by the clustering condition “month” to the clustering condition “year” through the position of the cluster 120c similarly classified by the clustering condition “quarter”. It moves to the position of the cluster 120d to be classified. In the figure, this movement process is indicated by (a) to (c).

  In this embodiment, the granularity of clustering related to the attribute “shooting date / time” becomes coarser as the clustering condition changes from “month” to “quarter” and “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 according to 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 those 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 exceeds the opening amount d1 at 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).

  Moreover, the display control part 13 changes the display of the position bar 130 according to the opening amount d similarly to 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 user's pinch-out operation. Although the case where the clustering granularity is made coarser by the pinch-out operation has been described here, similarly, the clustering granularity can be made finer by the pinch-in operation.

(Summary of this embodiment)
In the first embodiment of the present disclosure described above, content is newly clustered by a user's pinch-out operation, for example, as in a series of examples illustrated in FIGS. Gradually gets rougher. Also, the user's pinch-in operation gradually reduces the granularity of content clustering, and eventually the content becomes unclassified. Such a change in the clustering condition is displayed on the screen 100 as the movement of the content 110 accompanying the user's pinch operation.

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

  In the above description, “day”, “month”, “quarter”, and “year” are illustrated as the clustering conditions related to “shooting date and time”, but the present disclosure is not limited to this. For example, the clustering condition regarding “shooting date and time” may be set more finely, such as “30 minutes”, “1 hour”, “3 days”, “10 days”, and the like. By finely setting the clustering conditions, for example, in the continuous change of the clustering conditions as in the example illustrated in FIG. 4, it is possible to change the clustering granularity steplessly according to the pinch operation.

  In the above description, the user's pinch operation to the lower right portion of the screen 100 is exemplified 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 a pinch operation not only on the lower right side of the screen 100 but also at an arbitrary position on 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 a user pointing operation for a GUI such as a +/− button or a 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 first embodiment described above in that the condition setting unit 17 uses “shooting position” instead of “shooting date and time” as an attribute of the image content. Since the other points are the same as those in the first embodiment, detailed description thereof is omitted.

(Operation example)
In the present 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 a clustering condition “district” regarding the attribute “photographing position” of the image content, and the clustering unit 12 sets the clustering condition “district”. Classify image content into clusters. Furthermore, 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 “capturing position” in this embodiment, that is, information on the geographical position can be said to be positional information on the geographical space. In clustering based on the clustering condition “district”, the geographic space is divided into address areas (districts) of a predetermined hierarchy, and contents including position information in each of the divided areas are classified into the same cluster. The address area is a preset area that divides the geographic space hierarchically. In the present embodiment, “district” such as “Shibuya” as the lowest layer, “prefecture” such as “Tokyo” as the upper layer, and “country” such as “Japan” as the upper layer. The granularity of the 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 is moved 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 position of the cluster 220c classified as "." In the figure, this movement process is indicated by (a) to (c).

  In this embodiment, the clustering granularity related to the attribute “shooting position” becomes coarser as the clustering condition changes from “district” to “prefecture” and “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 according to this operation. In accordance with this, 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 finished during the movement, it is determined whether to confirm or discard the change of the clustering condition by comparing the opening amount d of the pinch-out operation with a predetermined threshold.

  As described above, in this embodiment, the clustering condition related to the attribute “shooting position” is set and changed by the user's pinch-out operation in the same manner as the clustering condition related to the attribute “shooting date and time” in the first embodiment. Is done. Although the case where the clustering granularity is made coarser by the pinch-out operation has been described here, similarly, the clustering granularity 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 of the content clustering condition according to the user's pinch operation, for example, as in the example illustrated in FIG. 5, the content attribute “shooting position” is set. It also applies to the clustering used. In content classification using location information in a geographic space, it is possible to use a hierarchy of predetermined address areas as the granularity of clustering. As a result, the range and name of the cluster are close to the geographical name known to the user, and the clustering result easily matches the user's desire.

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

  As the granularity of clustering, the address area hierarchy is not necessarily used as in the above example. For example, the clustering unit 12 may cluster content by partitioning the geographic space into grids, and the condition setting unit 17 may change the size of the grids 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 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. To do. Since the other points are the same as those in the first embodiment, detailed description thereof is omitted.

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

  Here, the attributes “artist” and “genre” in this embodiment are not positional information, unlike the first and second embodiments. These attributes are artist or genre names. Therefore, when contents are clustered according to 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 illustrating an example in which the clustering condition is 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 that is classified according to the clustering condition “artist”, and also the clustering condition “genre”. It moves to the position of the cluster 320b classified by. In the figure, this movement process is indicated by (a) to (d).

  Here, the content 310 is music content displayed in units of albums. 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 album-based content 310 is classified according to the music content attributes “artist” and “genre”. As described above, the clustering unit 12 and the display control unit 13 can treat a cluster in which content is classified under a certain clustering condition as content when the cluster is classified under another clustering condition. The content 310 can be displayed on the screen 100 as, for example, a reduced icon of an album jacket image.

  In the state of (a), no clustering condition is set in the clustering unit 12 for the music content in units of albums. 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 14. As shown in the figure, this pinch operation is a pinch out operation at the lower right portion of the screen 100.

  In response to this operation, the condition setting unit 17 that has acquired the information on the user's pinch-out operation via the touch panel 15 and the operation acquisition unit 16 performs clustering related to the attribute “artist” of the music content from a state in which no clustering condition is set. Change to 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 in a state classified into the cluster 320a as shown in (b). The cluster 320a can be displayed with artist names “A”, “B”, and “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 set independently, although there is some degree of relevance. In other words, music contents of the same artist may belong to different genres. For example, in (c), there is a content 310 that moves from a cluster 320a of “C” classified under the clustering condition “artist” to a cluster 320b of “Rock” under the clustering condition “genre”, and “Pops”. An example is shown in which there is content 310 that moves toward the other cluster 320b, and there is also content 310 that remains to form a “Techno” cluster 320b. Displaying such movement of the content 310 makes it easy 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 in accordance with the user's pinch operation are performed by “artist” and “ It is also applied during clustering using different attributes of content, such as “Genre”. As a result, the attributes used for content clustering can be changed with a simple operation. In addition, it is possible to visually grasp the change in the clustering result due to the change in the attribute.

  In the above description, “album”, “artist”, and “genre” are exemplified 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 perform multi-touch and a case where the drag operation is based on a single 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 in the first embodiment, detailed description thereof is omitted.

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

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

  From here, the display on 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 multi-touch drag operation is acquired by the operation acquisition unit 16 and 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 a drag operation by a single touch is acquired by the operation acquisition unit 16, 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), clusters 120a from “6/2” to “7/1” were displayed, whereas in (c), clusters from “6/8” to “8/3” were displayed. A cluster 120a is displayed. The display control unit 13 moves the position displayed on the position bar 130 in accordance with the scroll.

  On the other hand, when the multi-touch drag operation is acquired by the operation acquisition unit 16 in (d), 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”. In accordance with 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 in accordance with the change of the classification.

  In the figure, an example is shown in which the display is scrolled upward by an upward drag operation or the clustering granularity is coarsened. Similarly, the display is scrolled downward by a downward drag operation. It is also possible to make the granularity of clustering fine.

  FIG. 8 is a flowchart illustrating a process of the information processing apparatus 10 according to the fourth embodiment of the present disclosure. For the sake of simplification of explanation, the drawing shows processing when a drag operation in the vertical direction is acquired with respect to the screen 100 by the operation acquisition unit 16. In addition to the illustrated process, a process 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 otherwise, that is, a single touch. (Step S101). Here, when it is determined that the drag operation is based on multi-touch, clustering granularity change processing after step S103 is executed. On the other hand, if it is not determined that the drag operation is based on multi-touch, that is, if the drag operation is based on single touch, the display scrolling process after step S113 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). If it is determined that the drag operation is upward, the condition setting unit 17 coarsens the clustering granularity (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, 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 reduces the clustering granularity (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 content clustering under 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. The display is changed (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). If it is determined that the drag operation is 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).

  Through the processing as described above, in the present embodiment, the change of the clustering condition and the scroll operation are switched.

(Summary of this embodiment)
In the fourth embodiment of the present disclosure described above, for example, the first and second movement operations in the same direction according to the type of movement operation, as in the example illustrated in FIGS. 7 and 8. To change the clustering condition or scroll the display.

  Thus, for example, it is possible to change the clustering granularity by a multi-touch drag operation in the same direction while enabling a display scroll operation by a single touch drag operation. 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 operations and pinch 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 clustering granularity is changed by a multi touch drag operation. However, the present disclosure is limited to this. It is not something. For example, the display may be scrolled by a multi-touch drag operation in the vertical direction of the screen, and the clustering granularity may be changed by a single touch drag operation. Also, 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. Further, 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.

  In the fifth embodiment of the present disclosure, the clustering unit 12 clusters content using a plurality of attributes, and the condition setting unit 17 switches processing according to the direction of the pinch operation. Is different. Since the other points are the same as those in the first embodiment, detailed description thereof is omitted.

(Operation example)
9 to 11 are diagrams illustrating an example in which the clustering granularity change 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” and the attribute “shooting position”. For example, as illustrated in FIG. 9, the clustering unit 12 classifies the content 110 into clusters 420 a generated based on the clustering condition “day, district”. As a result, the content 110 is, for example, “content photographed in Shibuya on 6/2”, “content photographed in Shinagawa on 6/2”, and “content photographed in Shibuya on 8/3”. , Clustered for each 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 the geographic space, respectively, and can be said to be first and second position information. As described in the first embodiment above, in clustering using position information on the time axis, the clustering granularity changes by changing the length of dividing the time axis. Further, as described in the second embodiment, in clustering using location information in geospace, the clustering granularity changes by changing the hierarchy of address areas used for clustering. As described above, in the first and second position information used in the present embodiment, it is possible to change the granularity of clustering for each. 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 two pieces of position information as a screen 100 on the display 14. In the screen 100, a clustering condition related to the attribute “shooting date / time” is displayed on the horizontal axis, and a clustering condition related to the attribute “photographing position” is displayed on the vertical axis, and each cluster 420a is expressed by the coordinates of the two axes. Is done. That is, the cluster 420a in which the horizontal axis is “6/2” and the vertical axis is “Shibuya” is “content taken 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 the same as the position bar 130 displayed in the first embodiment or the like, but in this embodiment, the clustering condition related to the attribute “shooting date and time” is expressed on the horizontal axis. Are displayed in the horizontal direction.

  FIG. 10 shows a state in which the operation acquisition unit 16 has acquired a left / right pinch operation with respect to the screen 100 in the state of FIG. 9. At this time, the condition setting unit 17 changes the clustering condition related to the attribute “shooting date / time” from “day” to “month”. In accordance with 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 displayed in the same month, for example, “contents photographed in Shibuya in June”, “contents photographed in Shinagawa in June”, and “contents photographed 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 the clustering result. Here, the classification of the “district” on the vertical axis does not change, and the classification of the horizontal axis changes from “day” to “month”, so that each cluster 420a converges in the horizontal direction and cluster 420b. Form. Further, the display control unit 13 changes the display of the position bar 130 from a monthly unit to a three-month unit in accordance with a change in the clustering condition regarding the attribute “shooting date and time”.

  FIG. 11 shows a state in which the operation acquisition unit 16 has acquired a vertical pinch operation in the state of FIG. 9. At this time, the condition setting unit 17 changes the clustering condition regarding the attribute “shooting position” from “district” to “prefecture”. In accordance with this, the clustering unit 12 classifies the content 110 into clusters 420c that are generated based on the clustering condition “day, prefecture”. As a result, the content 110 is, for example, “contents taken in Tokyo on 6/2”, “contents taken in Saitama on 6/2”, “contents taken in Tokyo on 6/8”, and so on. , 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, since the classification of “day” on the left and right axis does not change, and the classification of the vertical axis changes from “district” to “prefecture”, each cluster 420a converges in the vertical direction and is clustered. 420c is formed. Since the clustering condition regarding the attribute “shooting date / time” does not change, the display control unit 13 does not change the display of the position bar 130.

  FIG. 12 is a flowchart illustrating a process of the information processing apparatus 10 according to the fifth embodiment of the present disclosure. In order to simplify the description, the drawing shows processing when a pinch operation in the horizontal direction or vertical direction of the screen 100 is acquired by the operation acquisition unit 16. In addition to the processing shown in the figure, processing when another type of operation is 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 horizontal pinch operation (step S201). If it is determined that the pinch operation is a left / right pinch operation, the clustering granularity changing process of the attribute “shooting date / time” after step S203 is executed. On the other hand, if it is not determined that the pinch operation is a left / right pinch operation, that is, if the pinch operation is a vertical pinch operation, clustering granularity changing processing of the attribute “shooting position” after step S209 is executed. .

  In the clustering granularity changing process of the attribute “shooting date”, first, the condition setting unit 17 determines whether or not the pinch operation is a pinch out (step S203). If it is determined that the pinch operation is a pinch out, the condition setting unit 17 coarsens the clustering granularity based on 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, if it is not determined that the pinch operation is a pinch-out, that is, if the pinch operation is a pinch-in, the condition setting unit 17 reduces the granularity of clustering based on the attribute “shooting date and time” (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 “photographing position”, the condition setting unit 17 first determines whether or not the pinch operation is a pinch out (step S209). If it is determined that the pinch operation is a pinch out, the condition setting unit 17 coarsens the clustering granularity based on the attribute “shooting 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, if it is not determined that the pinch operation is a pinch-out, that is, if the pinch operation is a pinch-in, the condition setting unit 17 reduces the clustering granularity based on the attribute “shooting position” (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” or “shooting position”, the condition setting unit 17 provides the changed clustering condition to the clustering unit 12, and the clustering unit 12 performs clustering of content under the provided conditions. 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. The display is changed to (Step S217).

  Through the processing as described above, in this embodiment, the change of clustering granularity in a plurality of attributes is switched.

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

  Thereby, for example, when content is clustered using two types of attributes, the granularity of clustering can be changed by an intuitive operation for any attribute. At this time, if the direction in which the two types of attributes are expressed as positions and the direction of the user's operation for changing the granularity of clustering by each attribute are associated, the change in the granularity of clustering by each attribute is changed. Operation is 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 clustering granularity may be changed by a drag operation or a flick operation. For example, when the clustering granularity is changed by a drag operation, the present embodiment may be combined with the fourth embodiment. In this case, for example, the display is scrolled vertically or horizontally in a single touch drag operation, and the clustering granularity is changed for one of two types of attributes in a multi touch drag operation.
