The touch panel 130 may include an optical sensor liquid crystal. The touch panel 130 detects a touch operation on the touch panel 130 by an external object every predetermined time, and inputs touch coordinates (touch position) to the CPU 110. That is, the CPU 110 sequentially acquires touch coordinates from the touch panel 130.

  As will be described later, when a user performs a predetermined touch operation on an initial screen (for example, a startup screen) displayed on the display 134, an object displayed on the menu screen is a dominant hand or an information processing device when the user performs a touch operation. 1 is arranged in a manner reflecting the gripping state of 1 and the like. A plurality of objects are displayed on the menu screen, and the user can perform processing corresponding to the object by selecting the object on the menu screen.

  The speaker 140 outputs sound based on a command from the CPU 110. For example, the CPU 110 causes the speaker 140 to output sound based on the sound data.

  The button 150 is disposed on the surface of the information processing apparatus 1, receives a command from the user, and inputs it to the CPU 110. The button 150 includes, for example, a screen transition button for transitioning the display screen, a confirmation button for a predetermined instruction, a cancel button, and the like.

  The memory interface (I / F) 160 reads data from the external storage medium 162. That is, the CPU 110 reads data stored in the external storage medium 162 via the memory interface 160 and stores the data in the memory 120. Conversely, the CPU 110 reads data from the memory 120 and stores the data in the external storage medium 162 via the memory interface 160.

Specifically, the CPU 110 displays the display screen on the display 134 in the same vertical orientation when the information processing device 1 is in the vertical orientation (when the user holds the information processing device 1 in the vertical orientation). The display direction is determined, and if it is in landscape orientation, it is determined to display in landscape orientation.

<C. Example of object placement settings>
First, an operation example (user interface) of object arrangement setting in information processing apparatus 1 according to the present embodiment will be described.

  When the user starts up the information processing apparatus 1, a startup screen is displayed on the display 134.

  FIG. 3 is a diagram showing an example of a startup screen displayed on display 134 of information processing apparatus 1 according to the present embodiment.

  Referring to FIG. 3, user interface screen 1000 displays an object 1002 indicating an activation icon for activating the menu screen, an arrow 1004, and a message 1006 that prompts a touch operation such as “Please move the activation icon in the direction of the arrow”. Including. That is, the user can activate the menu screen by moving the object 1002 in the direction of the arrow 1004.

  The object arrangement setting based on the touch operation mode performed by the user in response to the user interface screen 1000 will be described with reference to FIGS.

(C1. Example of operation (part 1))
Here, the user holds the information processing apparatus 1 with one hand, and moves the object 1002 (hereinafter simply referred to as “activation icon”) on the user interface screen 1000 in the direction of the arrow 1004 with the thumb of the hand. Think about the case.

  First, a case where the user holds the information processing apparatus 1 with the left hand and performs a touch operation with the thumb of the left hand will be described. In this case, it is assumed that the user uses the information processing apparatus 1 with one hand and has a habit of touching with the left hand, which is the dominant hand.

  FIG. 4 is a diagram showing an operation example in the case of performing object arrangement setting according to the present embodiment. FIG. 4A is an image diagram when the user holds the information processing apparatus 1 with the left hand and moves the activation icon with the thumb of the left hand. This is because when the information processing apparatus 1 is held with one hand, it is assumed that a touch operation is performed with the thumb of the hand. FIG. 4B is a diagram illustrating a movement locus in which the activation icon is moved by the touch operation of FIG. FIG. 4C is a diagram illustrating an object arrangement on the menu screen set based on the touch operation of FIG.

  Referring to FIG. 4, when the user holds information processing apparatus 1 with the left hand and moves the activation icon with the thumb of the left hand (see FIG. 4A), the touch operable range is the movable range of the thumb. Therefore, the range in which the user can move the activation icon is a small range. Accordingly, the radius of curvature R indicating the length between the center (estimated fulcrum position) of the arc drawn by the movement locus of the activation icon moved by the user and the end point (or starting point) of the movement locus is a small value (for example, 5 cm or less). It becomes. Further, since the user performs a touch operation with the thumb of the left hand, the movement direction of the movement locus is the upper left direction of the screen (see FIG. 4B). When the user's touch operation is completed (when the user releases his / her hand from the display 134), the screen is changed to a menu screen, and a plurality of objects on the menu screen are arranged in a form reflecting the touch operation (FIG. 4C). )reference). At this time, each object is arranged at a small interval in the vertical direction of the screen along the moving direction of the movement locus. In other words, each object is arranged in a range where the thumb of the left hand of the user can reach.

  Further, when the information processing apparatus 1 is a terminal device that can perform multi-touch, there is a possibility that an operation unintended by the user may occur when the palm of a hand touches the screen. Therefore, in this case, for example, the detection sensitivity of the touch panel 130 associated with a predetermined display area (a range in which erroneous input is assumed) on the lower left of the display 134 may be reduced.

  Next, a case where the user holds the information processing apparatus 1 with the right hand and performs a touch operation with the thumb of the right hand will be described. In this case, it is assumed that the user uses the information processing apparatus 1 with one hand and has a habit of performing a touch operation with the right hand that is the dominant hand. Basically, this is the same as the case where the left hand in FIG. 4 is replaced with the right hand.

  FIG. 5 is a diagram showing another operation example in the case where the object arrangement setting according to the present embodiment is performed. FIG. 5A is an image diagram when the user holds the information processing apparatus 1 with the right hand and moves the activation icon with the thumb of the right hand. FIG. 5B is a diagram illustrating a movement locus in which the activation icon has been moved by the touch operation of FIG. FIG. 5C is a diagram illustrating the object arrangement setting on the menu screen based on the touch operation of FIG.

  Referring to FIG. 5, when the user holds information processing apparatus 1 with the right hand and moves the activation icon with the thumb of the left hand (see FIG. 5A), the radius of curvature R of the movement path of the activation icon is It is small (for example, 5 cm or less), and the movement direction of the movement locus is the upper right direction of the screen (see FIG. 5B). When the user's touch operation is completed, the screen is changed to the menu screen, and the objects on the menu screen are arranged at small intervals in the vertical direction of the screen along the movement direction (right direction) of the movement locus (FIG. 5). (See (c)). In other words, each object is arranged in a range where the thumb of the right hand of the user can reach. In this case, for example, the detection sensitivity of the touch panel 130 associated with a predetermined display area at the lower right of the display 134 may be reduced.

  As described above, when the user grips the information processing apparatus 1 with the left hand, the object is arranged at a position where the user can easily operate with the left hand, and when the user grips the information processing apparatus 1 with the right hand, Objects are placed at positions where they can be easily manipulated.

(C2. Example of operation (2))
Here, consider a case where the user holds the information processing apparatus 1 with one hand and moves the activation icon on the user interface screen 1000 in the direction of the arrow 1004 with the wrist of the wrist as a fulcrum, for example. .

  First, a case where the user holds the information processing apparatus 1 with the right hand and performs a touch operation with the left wrist index finger as a fulcrum with the left hand index finger will be described. At this time, it is assumed that the user uses the information processing apparatus 1 with both hands and has a habit of touching with the left hand, which is the dominant hand, using the left wrist as a fulcrum.

  FIG. 6 is a diagram showing another operation example in the case of performing the object arrangement setting according to the present embodiment. FIG. 6A is an image diagram when the user holds the information processing apparatus 1 with the right hand and moves the activation icon with the index finger of the left hand. This is because when the information processing apparatus 1 is held with one hand, it is normal to perform a touch operation with the index finger having a large movable range of the other hand. FIG. 6B is a diagram illustrating a movement locus in which the activation icon has been moved by the touch operation of FIG. FIG. 6C is a diagram illustrating the object arrangement of the menu screen set based on the touch operation of FIG.

  Referring to FIG. 6, when the user holds information processing apparatus 1 with the right hand and moves the activation icon with the index finger of the left hand (see FIG. 6A), the user can move the activation icon. The range is relatively large. Therefore, the radius of curvature R of the movement path of the activation icon moved by the user is a relatively large (medium) value (for example, about 10 cm). In addition, since the user performs a touch operation with the left hand, the movement direction of the movement locus is the upper left direction of the screen (see FIG. 6B). When the user's touch operation is completed, the screen is changed to the menu screen, and the menu screen object is arranged in a form reflecting the touch operation (see FIG. 6C). That is, the objects are arranged at relatively large intervals in the vertical direction of the screen along the movement direction of the movement locus (see FIG. 6C). In other words, each object is arranged in a range where the index finger of the user's left hand can reach. In this case, for example, the detection sensitivity of the touch panel 130 associated with a predetermined display area on the lower right of the display 134 may be reduced.

  Next, a case where the user holds the information processing apparatus 1 with the left hand and performs a touch operation with the index finger of the right hand with the right wrist as a fulcrum, for example, will be described. At this time, it is assumed that the user uses the information processing apparatus 1 with both hands and has a habit of touching with the right hand, which is the dominant hand, with the right wrist as a fulcrum. This case is basically the same as that in FIG. 6 in which the left hand is replaced with the right hand and the right hand is replaced with the left hand.

  FIG. 7 is a diagram showing another operation example in the case of performing the object arrangement setting according to the present embodiment. FIG. 7A is an image diagram when the user holds the information processing apparatus 1 with the left hand and moves the activation icon with the index finger of the right hand. FIG. 7B is a diagram illustrating a movement locus in which the activation icon has been moved by the touch operation of FIG. FIG. 7C is a diagram showing the object arrangement of the menu screen set based on the touch operation of FIG.

  Referring to FIG. 7, when the user holds information processing apparatus 1 with the left hand and moves the activation icon with the index finger of the right hand (see FIG. 7A), the radius of curvature R of the movement path of the activation icon is The value is relatively large (medium) (for example, about 10 cm), and the movement direction of the movement locus is the upper right direction of the screen (see FIG. 7B). When the user's touch operation is completed, the screen is changed to the menu screen, and each object on the menu screen is arranged at a relatively large interval in the vertical direction of the screen along the moving direction (upper right direction) of the movement locus ( (Refer FIG.7 (c)). In other words, each object is arranged in a range where the index finger of the user's right hand can reach. In this case, for example, the detection sensitivity of the touch panel 130 associated with a predetermined display area at the lower left of the display 134 may be reduced.

  As described above, when the user grips the information processing apparatus 1 with the right hand, the object is arranged at a position where the user can easily operate with the left hand, and when the user grips the information processing apparatus 1 with the left hand, the user can easily operate with the right hand. The object is placed at a position where it can be manipulated.

(C3. Example of operation (part 3))
Here, the user holds the information processing apparatus 1 with one hand, and moves the activation icon on the user interface screen 1000 in the direction of the arrow 1004 by touching with the index finger of the other hand with the elbow as a fulcrum, for example. Consider the case that you want to let. This is similar to the operation example (No. 2) in that the user uses the information processing apparatus 1 with both hands, but the touch operation side is moved using the elbow as a fulcrum, so that the touch operation is movable. It differs in that the range becomes larger.

  First, a case where the user holds the information processing apparatus 1 with the right hand and performs a touch operation with the left index finger with the left elbow as a fulcrum will be described. At this time, it is assumed that the user uses the information processing apparatus 1 with both hands and has a habit of touching with the left hand, which is the dominant hand, with the left elbow as a fulcrum.

  FIG. 8 is a diagram showing another operation example in the case of performing object placement setting according to the present embodiment. FIG. 8A is an image diagram in a case where the user holds the information processing apparatus 1 with the right hand and moves the activation icon with the left index finger with the left elbow as a fulcrum. FIG. 8B is a diagram illustrating a movement locus in which the activation icon has been moved by the touch operation of FIG. FIG. 8C is a diagram showing the object arrangement of the menu screen set based on the touch operation of FIG.

  Referring to FIG. 8, when the user holds information processing apparatus 1 with the right hand and moves the activation icon with the index finger of the left hand using the left elbow as a fulcrum (see FIG. 8A), the user selects the activation icon. The range that can be moved is even larger than in the case of the above operation example (part 2). Therefore, the radius of curvature R of the movement locus of the activation icon moved by the user is a larger value (for example, about 30 cm) than in the operation example (No. 2). At this time, although the user performs a touch operation with the left hand, since the radius of curvature R is large, the movement direction of the movement locus is substantially the vertical (up and down) direction of the screen (see FIG. 8B). Then, when the user's touch operation is completed, the screen is changed to the menu screen, and the objects on the menu screen are arranged in a form reflecting the touch operation (see FIG. 8C). At this time, the objects are arranged in a line on the left and right from the left edge of the screen, which is the dominant hand (left hand) side, in order from the object with the highest priority. This is because when the user performs a touch operation with the index finger using the elbow as a fulcrum, it is possible to perform the touch operation in almost the entire area of the screen, and thus it is not necessary to arrange in the vertical direction. The high priority indicates, for example, that the use frequency is high or the preset importance is high.

  In this case, for example, the detection sensitivity of the touch panel 130 associated with a predetermined display area at the lower right of the display 134 may be reduced.

  Next, a case where the user holds the information processing apparatus 1 with the left hand and performs a touch operation with the index finger of the right hand using the right elbow as a fulcrum will be described. At this time, it is assumed that the user uses the information processing apparatus 1 with both hands and has a habit of touching with the right hand that is the dominant hand with the right elbow as a fulcrum. This case is basically the same as that in FIG. 7 in which the left hand is replaced with the right hand and the right hand is replaced with the left hand.

  FIG. 9 is a diagram showing another operation example in the case of performing the object arrangement setting according to the present embodiment. FIG. 9A is an image diagram when the user holds the information processing apparatus 1 with the left hand and moves the activation icon with the index finger of the right hand with the right elbow as a fulcrum. FIG. 9B is a diagram illustrating a movement locus in which the activation icon has been moved by the touch operation of FIG. FIG. 9C is a diagram showing the object arrangement of the menu screen set based on the touch operation of FIG. 9A.

  Referring to FIG. 9, when the user holds information processing apparatus 1 with the left hand and moves the activation icon with the index finger of the right hand using the right elbow as a fulcrum (see FIG. 9A), the movement locus of the activation icon Has a large radius of curvature R (for example, about 30 cm), and the movement direction of the movement locus is substantially perpendicular to the screen (see FIG. 9B). When the user's touch operation is completed, the menu screen is displayed, and the objects on the menu screen are arranged in a line on the left and right from the right edge to the left edge of the dominant hand (right hand) in order from the object with the highest priority. The

  In this case, for example, the detection sensitivity of the touch panel 130 associated with a predetermined display area at the lower left of the display 134 may be reduced.

<D. Functional configuration>
Next, a functional configuration for realizing a plurality of object arrangement settings provided by information processing apparatus 1 according to the present embodiment as described above will be described.

FIG. 10 is a functional block diagram of information processing apparatus 1 according to the present embodiment.
Referring to FIG. 10, information processing apparatus 1 has, as its functional configuration, position detection unit 210, analysis unit 220, correction unit 230, display control unit 240, storage unit 250, and sensitivity change unit 260. including. The analysis unit 220, the correction unit 230, the display control unit 240, and the sensitivity change unit 260 basically execute the program stored in the memory 120 by the CPU 110 of the information processing device 1, and the information processing device 1. This is realized by giving a command to the component. That is, the CPU 110 has a function as a control unit that controls the entire operation of the information processing apparatus 1. Note that some or all of these functional configurations may be realized by hardware.

  When the position detection unit 210 receives a touch input from the user, the position detection unit 210 sequentially outputs the detection result of the touched touch position to the analysis unit 220. Specifically, the position detection unit 210 uses the touch coordinates (X0, Y0) indicating the touch position (the initial position of the detected touch position) that is the starting point of the touch operation by the user as the end point of the touch operation. Touch coordinates up to coordinates (Xn, Yn) are sequentially output. Further, when the position detection unit 210 detects that a plurality of points are touched simultaneously, the position detection unit 210 outputs these touch coordinates. The position detection unit 210 is a function mainly realized by the touch panel 130.

  In response to the detection result of the position detection unit 210, the analysis unit 220 analyzes a movement locus drawn by the movement from the start point to the end point of the touch position. Specifically, the analysis unit 220 calculates the curvature radius of the movement locus by analyzing the touch coordinates of the movement locus acquired from the position detection unit 210. Further, the analysis unit 220 calculates the movement direction of the movement locus by comparing the touch coordinates that are the starting point of the movement locus and the touch coordinates that are the end point. Then, the analysis unit 220 outputs the analysis result to the correction unit 230 and the sensitivity change unit 260.

  The correction unit 230 corrects reference position information indicating a predetermined reference position of the object displayed on the menu screen in response to the analysis result of the analysis unit 220. Specifically, the correction unit 230 stores the objects so that the objects are arranged at the first interval in the vertical direction of the screen when the value of the radius of curvature of the movement locus acquired from the analysis unit 220 is the first value. The reference position information acquired from the unit 250 is corrected. The correction unit 230 sets the reference position information so that the object is arranged at a second interval larger than the first interval in the vertical direction of the screen when the value of the curvature radius is a second value larger than the first value. Correct. The correction unit 230 corrects the reference position information so that the object is arranged at an interval smaller than the first interval in the vertical direction of the screen when the value of the curvature radius is a third value larger than the second value. To do. Furthermore, the correction unit 230 corrects the reference position information so that the object is arranged along the movement direction of the movement locus. Then, the correction unit 230 outputs the corrected reference position information (corrected position information) to the display control unit 240.

  The display control unit 240 controls display on the display 134 based on the correction position information acquired from the correction unit 230. Specifically, the display control unit 240 controls the display of the display 134 so that the objects on the menu screen are arranged based on the correction position information. In another aspect, the display control unit 240 controls the display of the display 134 so that the activation object for activating the information processing device 1 on the activation screen is arranged on the user side holding the information processing device 1.

  The storage unit 250 stores various types of information. The storage unit 250 stores, for example, reference position information of objects on the menu screen. The storage unit 250 may store correction position information. The storage unit 250 is a function mainly realized by the memory 120.

  The sensitivity changing unit 260 reduces the detection sensitivity of the position detection unit 210 associated with a predetermined display area of the display 134 in response to the analysis result of the analysis unit 220. In other words, the sensitivity changing unit 260 specifies the display area of the display 134 that reduces the detection sensitivity of the position detection unit based on the radius of curvature of the movement locus and the movement direction.

<E. Flow chart>
Next, a flowchart showing a processing procedure for realizing the plurality of object arrangement settings shown in FIGS.

  FIG. 11 is a flowchart showing a processing procedure for object arrangement setting executed in information processing apparatus 1 according to the present embodiment.

  As an outline, first, the CPU 110 displays a startup screen on the display 134. As described above, when the user performs a predetermined touch operation, the CPU 110 analyzes the movement trajectory of the touch operation and calculates the curvature radius and the movement direction. In accordance with the analysis result, the CPU 110 performs object placement setting on the menu screen and reduces the detection sensitivity of the touch panel 130 in the corresponding display area of the display 134. Each step shown in FIG. 11 is basically realized by the CPU 110 executing a program.

  Referring to FIG. 11, CPU 110 (display control unit 240) displays a startup screen of display 134 (step S102). The display 134 displays the user interface screen 1000 shown in FIG. At this time, the CPU 110 (display control unit 240) controls the display on the display 134 so that the activation icon (object 1002) on the activation screen is arranged on the user side holding the information processing apparatus 1.

  Next, the CPU 110 determines whether an input by a touch operation has been received from the user via the touch panel 130 (position detection unit 210) (step S104). If CPU 110 has not received an input through a touch operation (NO in step S104), the process repeats step S104.

  On the other hand, when CPU 110 accepts an input by a touch operation (YES in step S104), CPU 110 (analysis unit 220) acquires a movement locus of the touch operation. Specifically, the CPU 110 (analysis unit 220) sequentially acquires touch coordinates indicating the touch position from the start point to the end point of the touch operation from the touch panel 130 (position detection unit 210). Then, CPU110 (analysis part 220) analyzes the acquired movement locus | trajectory, and acquires the curvature radius R and movement direction of the said movement locus | trajectory (step S107). Specifically, the CPU 110 (analysis unit 220) calculates the length of the arc and the center angle of the circle center (estimated fulcrum position), the start point and the end point based on the start point and end point of the movement locus (arc). By doing so, the radius of curvature R is acquired. In addition, the CPU 110 (analysis unit 220) acquires the movement direction from the touch coordinates of the start point and end point of the movement track. When the starting point of the movement trajectory is the origin, when the end point is on the left side of the screen from the origin (start point), the moving direction is negative, and when the end point is on the right side of the origin (start point), the moving direction is positive. Suppose there is.

  Next, the CPU 110 (correction unit 230) determines whether or not the moving direction is the left direction (step S108). This step S108 is processing for specifying the user's dominant hand (whether right-handed or left-handed). Specifically, CPU 110 (correction unit 230) determines whether or not the acquired movement direction is a negative direction. If the moving direction is not the left direction (the right direction) (NO in step S108), the process proceeds to step S124.

  On the other hand, when the movement direction is the left direction (YES in step S108), CPU 110 (correction unit 230) determines whether or not curvature radius R is equal to or smaller than the first threshold (step S110). ). Specifically, the CPU 110 (correction unit 230) compares the acquired curvature radius R with a predetermined first threshold (for example, 5 cm) to determine whether the curvature radius R is equal to or less than the first threshold. Determine whether. If curvature radius R is not less than or equal to the first threshold (greater than the first threshold) (NO in step S110), the process proceeds to step S116.

  On the other hand, when the radius of curvature R is equal to or smaller than the first threshold (YES in step S110), the CPU 110 grips the information processing apparatus 1 with the left hand and the left hand (for example, the thumb of the left hand). ), A menu screen assuming a case where a touch operation is performed is displayed (step S112). Specifically, first, the CPU 110 (correction unit 230) causes the memory 120 (storage unit) so that objects displayed on the menu screen are arranged along the movement direction at a first interval in the vertical direction of the screen. 250) is corrected. Then, the CPU 110 (display control unit 240) controls display on the display 134 based on the corrected reference position information (corrected position information). That is, at this time, a menu screen as shown in FIG.

  Next, the CPU 110 (sensitivity changing unit 260) reduces the detection sensitivity of the touch panel 130 (position detecting unit 210) associated with the lower left display area of the display 134 (step S114). For example, the CPU 110 (sensitivity changing unit 260) reduces the detection sensitivity in the display area within 1 cm from the lower left end of the display 134. Then, the process ends.

  Returning to step S110, if the curvature radius R is not less than or equal to the first threshold (NO in step S110), the CPU 110 (correction unit 230) determines whether or not the curvature radius R is less than or equal to the second threshold. Judgment is made (step S116). Specifically, the CPU 110 (correction unit 230) compares the acquired curvature radius R with a predetermined second threshold (for example, 10 cm) to determine whether the curvature radius R is equal to or smaller than the second threshold. Determine whether.

  Here, when the radius of curvature R is equal to or smaller than the second threshold value (YES in step S116), the user holds the information processing apparatus 1 with the right hand and a relatively large touch operation (for example, the left wrist) A menu screen that assumes the case of performing a touch operation with fulcrum as a fulcrum is displayed (step S118). Specifically, first, the CPU 110 (correction unit 230) causes the memory 120 (storage unit) so that objects displayed on the menu screen are arranged along the movement direction at a second interval in the vertical direction of the screen. 250) is corrected. Then, the CPU 110 (display control unit 240) controls display on the display 134 based on the corrected reference position information (corrected position information). That is, at this time, a menu screen as shown in FIG.

  On the other hand, when the radius of curvature R is not less than or equal to the second threshold (greater than the second threshold) (NO in step S116), the user holds the information processing apparatus 1 with the right hand and the left hand A menu screen is displayed assuming a case where a considerably large touch operation (for example, a touch operation with the left elbow as a fulcrum) is performed (step S120). Specifically, first, the CPU 110 (correction unit 230) arranges the objects displayed on the menu screen in a line on the left and right from the left edge to the right edge on the dominant hand (left hand) side in order from the object with the highest priority. Thus, the reference position information is corrected (corrected position information). In other words, the CPU (correction unit 230) corrects the reference position information so that the objects are arranged at intervals smaller than the first interval in the vertical direction of the screen. Then, the CPU 110 (display control unit 240) controls display on the display 134 based on the correction position information. That is, at this time, a menu screen as shown in FIG.

  Next, when the menu screen corresponding to step S118 or step S120 is displayed, CPU 110 (sensitivity changing unit 260) of touch panel 130 (position detecting unit 210) associated with the display area at the lower right of display 134 is displayed. The detection sensitivity is lowered (step S122). For example, the CPU 110 (sensitivity changing unit 260) reduces the detection sensitivity in the display area within 1 cm from the lower right end of the display 134. Then, the process ends.

  Steps S110 and S116 described above are processes for specifying the user's gripping state (a mode in which a touch operation is performed).

  Next, returning to step S108, the case where the movement direction is the right direction (NO in step S108) will be described. The following processing contents basically correspond to the case where the left and right are reversed in steps S110 to S122. Accordingly, the processing contents of the following steps S124 to S136 will be described briefly without repeating detailed description.

  In step S124, the CPU 110 (correction unit 230) determines whether or not the radius of curvature R is equal to or less than the first threshold value. When the curvature radius R is equal to or smaller than the first threshold value (YES in step S124), CPU 110 (correction unit 230, display control unit 240) holds information processing apparatus 1 with the right hand, and the right hand ( For example, a menu screen assuming a case where a touch operation is performed with the thumb of the right hand) is displayed (step S126). That is, at this time, a menu screen as shown in FIG.

  Next, the CPU 110 (sensitivity changing unit 260) reduces the detection sensitivity of the touch panel 130 (position detecting unit 210) associated with the lower right display area of the display 134 (step S128). Then, the process ends.

  Returning to step S124, if the curvature radius R is not less than or equal to the first threshold (NO in step S124), the CPU 110 (correction unit 230) determines whether or not the curvature radius R is less than or equal to the second threshold. Judgment is made (step S130). When the curvature radius R is equal to or smaller than the second threshold value (YES in step S130), CPU 110 (correction unit 230, display control unit 240) grips information processing apparatus 1 with the left hand and the right hand. A menu screen is displayed assuming that a relatively large touch operation (for example, a touch operation with the right wrist as a fulcrum) is performed (step S132). That is, at this time, a menu screen as shown in FIG.

  On the other hand, when the curvature radius R is not less than or equal to the second threshold value (NO in step S130), the user holds the information processing apparatus 1 with the left hand and the touch operation (for example, right A menu screen that assumes the case of performing a touch operation using the elbow as a fulcrum) is displayed (step S134). That is, at this time, a menu screen as shown in FIG.

  Next, when the menu screen corresponding to step S132 or step S134 is displayed, the CPU 110 (sensitivity changing unit 260) detects the touch panel 130 (position detecting unit 210) associated with the lower left display area of the display 134. The sensitivity is lowered (step S136). Then, the process ends.

  Steps S124 and S130 described above are processes for specifying the user's gripping state (a mode in which a touch operation is performed).

  In the above, the step of displaying the menu screen in which the object placement setting is made in a form reflecting the touch operation (for example, step S112) and the step of decreasing the detection sensitivity (for example, step S114) are processed in the reverse order. May be performed.

  As described above, information processing apparatus 1 according to the present embodiment identifies the dominant hand (left hand or right hand) of the user's touch operation from the moving direction of the movement track of the touch operation, and the value of the radius of curvature of the moving track. From this, the user's gripping state is specified. Then, the information processing apparatus 1 arranges the objects on the menu screen in a form that reflects the dominant hand and the gripping state.

  In another aspect, the CPU 110 performs display control of the display unit (display 134), executes processing in response to the detection result of the touch panel 130, and moves the touch operation by the user to the display 134. Based on the trajectory, the user's dominant hand and the gripping state of the information processing apparatus 1 are specified, and the objects are rearranged based on the specified result.

<F. Other Embodiments>
In the above description, the case where the value of the radius of curvature is divided into three using the first threshold and the second threshold has been described. However, the value of the radius of curvature is divided into three or more by further providing a threshold. May be. At this time, the pattern of the object arrangement setting may be increased so as to correspond to the number of sections with an increased radius of curvature.

  In the above description, the case where the number of objects arranged on the left and right in the plurality of object arrangement setting patterns is a fixed number (six) has been described, but the present invention is not limited to this. For example, when the display 134 is large or the like, when performing a touch operation with one hand, there is a possibility that the screen does not reach from one end to the other end. Therefore, in such a case, the number of objects displayed in the left-right direction may be reduced so as to be within the reach of the finger. Note that the user may be able to confirm an object that has not been displayed by performing a slide operation to the left and right.

  It is also possible to provide a program that causes a computer to function and execute control as described in the above flow. Such a program is recorded on a non-temporary computer-readable recording medium such as a flexible disk attached to the computer, a CD-ROM (Compact Disk-Read Only Memory), a ROM, a RAM, and a memory card, and the program product Can also be provided. Alternatively, the program can be provided by being recorded on a recording medium such as a hard disk built in the computer. A program can also be provided by downloading via a network.

  The program may be a program module that is provided as part of an operating system (OS) of a computer and that calls necessary modules in a predetermined arrangement at a predetermined timing to execute processing. In that case, the program itself does not include the module, and the process is executed in cooperation with the OS. A program that does not include such a module can also be included in the program according to the present invention.

  The program according to the present invention may be provided by being incorporated in a part of another program. Even in this case, the program itself does not include the module included in the other program, and the process is executed in cooperation with the other program. Such a program incorporated in another program can also be included in the program according to the present invention.

  In addition, whether the user uses the information processing device with one hand or both hands, and when using both hands, the user can move the hand with the wrist as a fulcrum or move the hand with the elbow as a fulcrum. Since it can be specified, a variation can be added to the object displayed on the screen.
