[Constitution]
FIG. 1 is a block diagram showing a hardware configuration of an information processing device 100 according to an embodiment of the present invention. The information processing device 100 includes a control unit 110, a storage unit 120, a communication unit 130, and a touch screen unit 140. The information processing device 100 may be configured to include other components (not shown) such as a speaker, a microphone, and a vibrator, or may be provided with input means (various keys, etc.) other than the touch screen unit 140. Good.

The control unit 110 is a means for controlling the operation of each unit of the information processing device 100. The control unit 110 includes a CPU (Central Processing Unit), an arithmetic processing device such as an application processor, and a memory (main storage device), and controls the operation of each unit of the information processing device 100 by executing a program. Further, the control unit 110 has a function of controlling the display on the touch screen unit 140. This function may be implemented at the OS (Operationg System) level, or may be realized by a predetermined application program.

The storage unit 120 is a means for storing data used in the information processing device 100. The storage unit 120 is composed of, for example, a flash memory or a hard disk. Further, the storage unit 120 may include a reader / writer of a removable storage medium (removable media) such as a memory card, and may have a configuration in which data can be exchanged with the storage medium. The storage unit 120 stores a program executed by the control unit 110 and data (image data, a table described later, etc.) used in association with the execution of the program.

The communication unit 130 is a means for transmitting and receiving data via a network. The network may include, for example, a fixed communication network such as the Internet, or a wireless communication network such as a mobile communication network or a wireless LAN (Local Area Network). The communication unit 130 includes, for example, a baseband processor and an antenna, and performs modulation and demodulation according to the network to transmit and receive data. Further, the communication unit 130 may include a configuration in which the communication unit 130 is directly connected to another information processing device (that is, without going through a network) by NFC (Near Field Communication) or the like.

The touch screen unit 140 is a means for displaying an image and accepting a user's operation. The touch screen unit 140 includes a display unit 141 and a sensor unit 142. The display unit 141 includes a display panel composed of a liquid crystal element, an organic EL (electroluminescence) element, and a drive circuit thereof, and displays an image according to the image data supplied from the control unit 110. The sensor unit 142 performs operations on the display area of the display unit 141 by the user (the display area of the display unit 141 and the operation area of the sensor unit 142 overlap) by a predetermined method (resistive film method, capacitance method, etc.). The control unit 110 is provided with an operation data indicating the operation of the user. The input data here is, for example, data indicating a position (coordinates) on the display area (operation area). The operation referred to here is typically performed with a fingertip, but may be performed with an instrument such as a stylus pen.

In the information processing device 100, objects (so-called icons) corresponding to different functions are displayed, and when any object is selected by the user, the function corresponding to the object is realized.

FIG. 2 is a diagram illustrating a screen on which a group of objects is displayed. In the display area of the touch screen unit 140 shown in FIG. 2, for example, an object A1 for searching restaurant information, an object A2 for displaying news, and objects A3 to A8 for realizing different functions are provided. Is displayed in a state of being arranged along a virtual circle C. Objects A1 to A8 correspond to so-called icons. The number of objects displayed on the screen may be larger or smaller than the number shown in the figure.

Objects A1 to A8 can accept an operation of a user who specifies a direction. When the information processing apparatus 100 receives an operation for designating a direction in the objects A1 to A8, the information processing apparatus 100 realizes a function corresponding to the object according to the direction specified by the operation. The operation of specifying the direction is a "flick operation" in which the user swipes lightly while keeping the finger in contact with the display area, but it is possible to specify a certain direction starting from a certain position. Any operation may be used as long as it is a simple operation.

FIG. 3 is a diagram illustrating an operation of selecting an object. It is assumed that the user performs a flick operation in the direction in which a desired object exists when viewed from the starting point, starting from a position approximately at the center of the circle C. By performing the operation of specifying the direction by the user in this way, from the reference point with a predetermined reference point (here, the same as the start point of the above operation, that is, the start point and the reference point are at the same position) as a reference. The object that exists in the direction of the above operation is selected. In the case of FIG. 3, the object A2 is selected by performing a flick operation such that the user's finger moves from the position of F to the position of F'along the direction M.

FIG. 4 is a diagram illustrating a range of operations in which an object can be selected. Here, the direction from the start point P (reference point P) to the object (here, the direction toward the center of the object) is defined as the reference direction H. When the direction specified by the user's operation falls within the range of plus or minus 5 degrees centered on the reference direction H from the start point P (here, plus is the clockwise direction centered on the start point P, and minus is counterclockwise. In the clockwise direction), the object is selected. Therefore, in the example of the figure, when the direction specified by the user's operation is M1, the object A is selected, but when the direction specified by the user's operation is M2, the object A is not selected.

FIG. 5 is a diagram for explaining an angle D formed by a direction M designated by a user operation and a reference direction H. As described above, if the angle D is within 5 degrees, the object A is selected, and if the angle D exceeds 5 degrees, the object A is not selected. When the object A is selected, this angle D corresponds to the difference between the operation performed by the user and the reference operation as a reference when selecting the object.

Each time an object is selected, the information processing apparatus 100 aggregates the above angles D for each object and calculates the average value thereof. FIG. 6 is a diagram illustrating a difference table in which the average value of the differences is described. The difference table is stored in the storage unit 120.

In the difference table, the object ID for identifying each object, the direction in which the object is located, and the average difference, which is the average value of the operation difference (angle D described above) when the object is selected, are described. Has been done. The direction of the objects is the direction of each object as seen from the center (reference point) of the circle C. The direction of the object A1 is 0 degrees, the direction of the object A2 is 45 degrees, the direction of the object A3 is 90 degrees, and the direction of the object A4. The direction is 135 degrees, the direction of object A5 is 180 degrees, the direction of object A6 is 225 degrees, the direction of object A7 is 270 degrees, and the direction of object A8 is 315 degrees.

Depending on the user, there are strengths and weaknesses in each direction for the flick operation that specifies the direction, so the average difference will differ for each object. In the example of the figure, for example, the direction of operation when designating a certain direction of object A1 (object ID: OB01) has an average deviation of +3 degrees with respect to the reference direction. The plus of the average difference means the difference in the clockwise direction about the reference point, and the minus means the difference in the counterclockwise direction. For example, for object A4 (object ID: OB04), the average difference is -4 degrees, which is close to -5 degrees illustrated in FIG. 4, so the operation of selecting this object A4 fails at a considerable rate. It is expected that there will be. That is, the user is not good at the operation of specifying the direction of 135 degrees. It is expected that he is also not good at the operation of designating the direction of 225 degrees. On the other hand, since the average difference is -1 degree for the operation of specifying the direction of 45 degrees, it is expected that the user is relatively good at the operation of specifying this direction.

As the difference between the reference operation and the operation performed by the user, in addition to the average value of the angles illustrated in FIG. 6, the average value of the absolute values of the difference between the angles, the variance of the angle (sample variance), and the like are used. You may use it. In short, it may mean the difference between the operation performed by the user and the reference operation.

Further, the detection of the difference between the reference operation and the user operation may be performed at all times in the operation normally performed by the user. That is, the information processing apparatus 100 has a straight line (reference operation) to the start point of the user's flick operation and the selected object (the center position thereof), the start point of the user's flick operation, and the flick when the object is actually selected. The difference in the angle formed by the straight line specified by the operation is constantly recorded.

The information processing device 100 stores the frequency table in the storage unit 120 in order to arrange the objects frequently used by the user in the object group in the direction of the operation that the user is good at. FIG. 7 is a diagram illustrating a frequency table in which the frequency of use for each object by the user is described. Object A1 with object ID: OB01 has been selected 12 times in the past for a certain period of time, object A2 with object ID: OB02 has been selected once in the past, and object ID: OB03. Object A3 has been selected 0 times in the past, object A4 with object ID: OB04 has been selected 56 times in the past, and object A5 with object ID: OB05 has been selected in the past. 8 times, object A6 with object ID: OB06 has been selected 2 times in the past, object A7 with object ID: OB07 has been selected 16 times in the past, and object ID: OB08. Object A8 has been selected 24 times in the past. The past fixed period is arbitrarily determined.

FIG. 8 is a block diagram showing a functional configuration of the information processing apparatus 100. The control unit 110 of the information processing device 100 functions as an operation reception unit 101, a calculation unit 102, a specific unit 103, an arrangement unit 104, a display control unit 105, a selection unit 106, and a processing unit 107. The control unit 110 realizes each function such as an operation reception unit 101, a calculation unit 102, a specific unit 103, an arrangement unit 104, a display control unit 105, a selection unit 106, and a processing unit 107 by software processing.

The operation reception unit 101 receives an operation by the user. The calculation unit 102 is performed by the user when the user performs an operation of designating a direction starting from a position in the operation area and an object existing in the direction with respect to the reference point in the operation area is selected. Calculate the difference between the operation and the reference operation that serves as the reference when selecting an object. More specifically, the calculation unit 102 calculates the difference based on the angle formed by the direction (direction M in FIG. 5) and the reference operation direction (reference direction H in FIG. 5) specified by the user's operation. To do.

The identification unit 103 specifies the frequency of selection by the user for each object. The arrangement unit 104 arranges each object based on the above difference. Specifically, the arrangement unit 104 arranges the object based on the difference calculated for each of the plurality of operations performed by the user. More specifically, the arrangement unit 104 arranges the first object in the direction in which the difference is the first value, and in the direction in which the difference is the second value smaller than the first value, the arrangement unit 104 arranges the first object. Place a second object that is selected more often than the first object.

The display control unit 105 controls the display of the objects arranged by the arrangement unit 104 on the display unit 141. The selection unit 106 selects an object that exists in the direction specified by the user when viewed from the start point. The processing unit 107 performs processing according to the selected object and realizes a function corresponding to the object.

[motion]
FIG. 9 is a flowchart showing a process executed by the information processing apparatus 100. The calculation unit 102 of the information processing device 100 acquires the operation history of the user (step S11). The operation history referred to here includes the contents of the difference table and the frequency table. The content of the difference table is the result of the calculation unit 102 calculating the difference between the operation performed by the user and the reference operation that serves as a reference when selecting an object. The content of the frequency table is the result of the specific unit 103 specifying the frequency selected by the user for each object.

Next, the arrangement unit 104 refers to the frequency table and arranges the objects in descending order of the selected frequency (step S12). In the example of FIG. 7, the order is object ID: OB04, object ID: OB08, object ID: OB07, object ID: OB01, object ID: OB05, object ID: OB06, object ID: OB02, object ID: OB03.

Next, the arrangement unit 104 refers to the difference table and arranges the directions in ascending order of the average difference (step S13). In the example of FIG. 6, the degrees are 45 degrees, 90 degrees, 270 degrees, 0 degrees, 180 degrees, 315 degrees, 135 degrees, and 225 degrees.

Next, the arrangement unit 104 associates objects with high frequency from an angle having a small average difference (step S14). In the case of this example, the object ID: OB04 is associated with the angle of 45 degrees, the object ID: OB08 is associated with the angle of 90 degrees, the object ID: OB07 is associated with the angle of 270 degrees, and the object ID: OB01 is associated with the angle of 0 degrees. Correspondence, the object ID: OB05 is associated with the angle 180 degrees, the object ID: OB06 is associated with the angle 315 degrees, the object ID: OB02 is associated with the angle 135 degrees, and the object ID: OB03 is associated with the angle 225 degrees. As a result, the first object is placed in the direction in which the difference is the first value, and the frequency is higher than that in the direction in which the difference is the second value smaller than the first value. Many second objects are placed.

Next, the display control unit 105 controls to display the objects arranged by the arrangement unit 104 on the display unit 141 (step S15).

As described above, according to the present embodiment, since the objects having a high selection frequency are arranged in the direction in which the user is good at, a user interface that is easy to operate even for a user who is not good at the operation is realized.

[Modification example]
The present invention is not limited to the embodiments described above. The above-described embodiment may be modified as follows. Further, the following two or more modified examples may be combined and carried out.
[Modification 1]
The arrangement unit 104 arranges the objects based on the difference table and the frequency table as described above when the number of objects to be arranged is equal to or more than the threshold value, and when the number of objects to be arranged is less than the threshold value, the objects are arranged. The arrangement of the objects may be fixed so as not to be changed. This is because when there are few objects, it is less likely that an operation error or difficulty in operation will occur as compared with the case where there are many objects.

[Modification 2]
The arrangement unit 104 may adjust the arrangement interval of the objects according to the direction of the user's strengths and weaknesses. That is, the arrangement unit 104 arranges the first object group in the operation area including the direction in which the difference from the reference operation is the first value, and the difference from the reference operation is smaller than the first value. The second object group is arranged closer than the first object group in the operation area including the direction having a value of 2. For example, objects are arranged at predetermined intervals in the direction in which the operation is good, and objects are arranged at intervals wider than the predetermined interval in the direction in which the operation is not good, or in the direction in which the operation is good. An example of arranging objects at intervals closer than the interval and arranging objects at predetermined intervals in the direction that you are not good at, or arranging objects at intervals that are closer than the predetermined interval in the direction that you are good at operating. In the direction that you are not good at, you can think of an example of arranging objects at intervals wider than a predetermined interval.

[Modification 3]
The calculation unit 102 refers to a reference operation based on a direction based on a fixed axis in the operation area of the information processing device 100 and a direction based on a different axis depending on the posture of the information processing device 100. The difference may be calculated. That is, the calculation unit 102 calculates the difference according to the posture of the own device. Specifically, the vertical direction of the information processing device 100 is detected by a gyro sensor, for example, when the long side of the operation area of the information processing device 100 is parallel to the ground and when the short side of the operation area is parallel to the ground. Calculate the direction of the user's strengths and weaknesses in each of the above.

[Modification example 4]
The calculation unit 102 may calculate the difference from the reference operation not from the angle but from the imperfections of the straight line drawn by the operation. That is, the degree of the straight line of the finger movement trajectory from the start point of the operation to the arrival at the selected object is observed. For example, it is calculated how long the movement distance of the contact position with respect to the operation area of the finger from the start point to the selection of the object is longer than that of the straight line from the start point to the selected object. That is, it is presumed that the operation is in a direction that is not good. In this way, the calculation unit 102 may calculate the difference based on the difference between the distance on the operation area where the operation is performed by the user and the distance on the operation area of the reference operation.

[Modification 5]
The calculation unit 102 may calculate the difference from the reference operation from the difference in the locus at the time of operation instead of the angle. In other words, it is possible to find out how far the contact position with respect to the operation area of the finger has passed compared to the straight line from the start point to the center of the selected object, and the operation is not as accurate as passing through the far point. In other words, it is presumed that the operation is in a direction that is not good. That is, the calculation unit 102 calculates the difference based on the distance between the locus on the operation area where the operation is performed by the user and the locus on the operation area of the reference operation.

[Modification 6]
The start point and the reference point may be different. In this case, the selection unit 106 selects an object that exists in the direction specified by the user at the start point when viewed from the reference point. That is, as shown in FIG. 10, the reference direction H from the predetermined reference point P toward the object A is compared with the operation direction M from the start point S, and these are in the same direction within a predetermined range. If it is determined to be an operation, it is assumed that object A is selected. In this case, the object does not have to exist on the extension of the operation direction from the start point S.
