Description

  The present invention relates to a user interface, and more particularly to an information processing apparatus that performs a predetermined process in response to an operation for displacing an input position.

  In recent years, mobile terminals equipped with touch panels such as smartphones and tablet terminals have been used in various situations. Along with this, there are increasing opportunities to hold and operate a mobile terminal equipped with a touch panel with one hand. When holding and operating with one hand, the base of the thumb is often fixed to hold the terminal. As a result, the range of motion of the thumb itself becomes a semi-arc shape with the base at the center, and even if it is intended to move straight in the vertical direction, the finger may be moved in an oblique direction. Therefore, the operation intended by the user is not performed, and the user may feel that the operability is not good.

  As a method for solving such a problem relating to operability when a finger is moved in an oblique direction (finger is displaced) with respect to a direction to be determined for operation against the user's intention, Patent Document 1 discloses. Indicates the horizontal and vertical directions of the screen depending on the result of comparing at least one of the horizontal and vertical coordinate values of the current touch point with the touch start point in the drag operation on the touch screen as the origin to a predetermined threshold value. A scroll control device that restricts scrolling in at least one direction has been proposed.

  However, in the conventional technology as described above, since the operation such as scrolling in one axis direction such as the vertical direction and the horizontal direction is performed based on the operation length in the one axis direction, the operation in the oblique direction with respect to the one axis direction is performed. When there is an operation, the processing is determined based on the distance of the user's operation, that is, a value smaller than the displacement amount of the input position (the uniaxial component of the displacement amount of the input position). For this reason, there is a problem that an event occurs in which the amount of operation is smaller or does not operate than the user assumes. The present invention has been made in view of the above problems, and its purpose is to provide an amount of displacement of the input position even when the input position is displaced in a direction different from the direction for executing the processing. It is to provide an information processing apparatus or the like that performs processing according to the above.

  In order to solve the above-described problem, an information processing apparatus according to an aspect of the present invention performs a predetermined process on an object that is a target of the process according to the amount and direction of displacement of the input position. An effective direction determination means for determining whether or not an effective direction, which is the direction of displacement for executing the processing, is determined as a uniaxial direction based on the object, and the effective direction When the input position is displaced in a different direction and the effective direction determination means determines that the effective direction is determined as a uniaxial direction, the displacement amount is shifted to the effective direction. Displacement adjusting means for adjusting the amount of displacement.

  According to one aspect of the present invention, even when the input position is displaced in a direction different from the direction for executing the process, the process according to the amount of displacement of the input position can be performed. Play.

Embodiment 1
A first embodiment (Embodiment 1) of the present invention will be described with reference to FIGS.

[Outline of smartphone 1]
A smartphone (information processing apparatus) 1 includes a touch panel 10 and a control unit 20. On the input surface of the touch panel, a Y axis and an X axis perpendicular to the Y axis are defined, and a direction along these axes is referred to as an axial direction. This will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of conversion of operation displacement by the smartphone 1. As shown to (a) of the figure, a Y-axis is an axis along the longitudinal direction of the input surface of the touch panel 10, and an X-axis is an axis orthogonal to this. The Y-axis direction can also be expressed as the up-down direction, and the X-axis direction can be expressed as the left-right direction. The smartphone 1 has a displacement (hereinafter referred to as an operation displacement) indicated by an operation on the touch panel 10 in an axial direction different from the Y-axis direction illustrated in FIG. 4A (the X-axis direction illustrated in FIG. 4B). If the size and direction of (represent) are not reflected in the process, the process is determined according to the amount of displacement of the touch position and the direction in the Y-axis direction. For example, when a display image (object) that can be scrolled only in the Y-axis direction is displayed on the touch panel 10 and the user performs an operation indicating an operation displacement in the upper right direction as illustrated as the operation displacement d3 in FIG. The smartphone 1 performs the same scrolling process as when the operation displacement y2 in the upward direction having the magnitude of the operation displacement d3 is shown. As a result, as shown in FIG. 4A, compared to the case where the scroll process in the Y-axis direction is performed using y1, which is the Y-axis direction component of the operation displacement d3, the distance that the user moves the finger is scrolled. Since the amount is accurately reflected, it is possible to improve the user's operational feeling.

  In addition, the function equivalent to the function with which the smart phone 1 was provided is realizable also with a mobile telephone, a personal computer, a tablet-type terminal etc. That is, as long as the device can input and output necessary information, the device may not be a smartphone.

  As shown in FIG. 1, the touch panel 10 includes an input unit 11 and a display unit 12. The input unit 11 is arranged at a position to be superimposed on the display screen of the display unit 12, converts a touch on the touch panel 10 with a finger or a stylus into a signal, and outputs the signal to the control unit 20. As a method for converting a touch such as a finger or a stylus into a signal, an electrostatic induction method, a resistance film method, an optical method, or the like is used. Note that the touch is an operation including at least one of proximity to and contact with a specific target. The display unit 12 receives display image information from the control unit 20 and displays the information on the display screen. The display unit 12 includes a display element such as an LCD (Liquid Crystal Display) or an EL (Electroluminescence) display, and a driver circuit that drives the display element based on received image data.

  As illustrated in FIG. 1, the control unit 20 includes a position detection unit 21, a displacement calculation unit 22, a displacement adjustment unit 23, a scroll control unit 24, an effective direction determination unit 25, and a display information acquisition unit 26. The control unit 20 performs information processing based on the signal output from the input unit 11 and causes the display unit 12 to display an image.

  The position detection unit 21 receives a signal output from the input unit 11 and detects a touch position. The position detection unit 21 sequentially outputs the detected touch position to the displacement calculation unit 22.

  The displacement calculation unit 22 calculates an operation displacement that is a displacement of the input position in the input unit 11 and outputs the operation displacement to the displacement adjustment unit 23. Specifically, when the touch to the input unit 11 is continuously maintained, the displacement of the touch position is calculated as the operation displacement at regular time intervals (hereinafter, referred to as sampling time). For example, when the touch position at a certain time is (X1, Y1) and the touch position at the time when the sampling time has elapsed is (X2, Y2), the operation displacement is (ΔX, ΔY) shown in (1). is there.

(ΔX, ΔY) = (X2-X1, Y2-Y1) (1)
The display information acquisition unit 26 acquires display information (content) that is information for generating an image to be displayed on the display unit 12, and outputs the display information (content) to the effective direction determination unit 25. Further, the display information acquisition unit 26 converts the acquired display information into an image and outputs the image to the scroll control unit 24. The display information acquisition unit 26 includes means for acquiring HTML (Hyper Text Markup Language) data, image data, and the like, and an HTML rendering engine.

  Note that the image output to the scroll control unit 24 is a target (object) on which processing (here, scroll processing) is performed according to the drag operation in the present embodiment. In other words, an object is an image that can be scroll-displayed on the display screen by a drag operation. The object may be displayed on the entire display screen, such as a standby screen. Further, for example, the object divides an image displayed in a window different from the browsing screen popped up on the browsing screen, an image displayed in a part of the frame in the window, or one page. It may be displayed on a part of the display screen like an image displayed in a frame obtained in this way (for example, an inline frame embedded in a page). Furthermore, one object may be composed of a plurality of elements such as characters and moving images.

  The effective direction determination unit 25 (effective direction determination means) determines whether or not the effective direction, which is the direction of operation displacement for causing scrolling, is determined in the Y-axis direction. For example, in the meta information of HTML data included in the display information output from the display information acquisition unit 26, <meta name = "viewport" content = "width = device-width, initial-scale = 1.0, user-scalable = yes If it is specified that the display width of the display information is equal to the device width as in "/>, that is, if the scrollable direction is only the Y-axis direction, it is determined that the effective direction is only the Y-axis direction. To do. The effective direction determination unit 25 outputs the determination result to the displacement adjustment unit 23 and the scroll control unit 24.

The displacement adjuster 23 (displacement adjuster) determines whether or not a drag operation has been performed based on the operation displacement output from the displacement calculator 22. Specifically, the drag operation is performed when the displacement of the input position equal to or greater than a predetermined threshold occurs in the effective direction of the drag operation determined according to the display image (object) generated based on the content. It is determined that In addition, the displacement adjustment unit 23 determines that the drag operation has been performed when the effective direction determination unit 25 determines that the effective direction is determined as a uniaxial direction (for example, the Y-axis direction), and When the direction of the operation displacement is different from the effective direction, the operation displacement is adjusted. Specifically, the amount of operation displacement (movement distance of the touch position) is set as the amount of displacement in the Y-axis direction, and the amount of displacement in the X-axis direction is set to zero and notified to the scroll control unit 24. For example, when the displacement calculating unit 22 outputs the operation displacement d3: (ΔX, ΔY) shown in FIG. 4B, the displacement adjusting unit 23 is displaced y2: (0, a (ΔX ² + ΔY ² ) ^1/2. ) To the scroll control unit 24. Note that a indicates the direction of displacement in the effective direction. If ΔY is positive, a = 1, and if negative, a = −1.

The scroll control unit 24 scrolls the image output from the display information acquisition unit 26 and displays the image on the display unit 12. Specifically, when the effective direction determination unit 25 determines that the effective direction is only the Y-axis direction, that is, when the scrollable direction is only the Y-axis direction, the displacement notified by the displacement adjustment unit 23 Based on the above, the scroll control unit 24 determines the size and direction of the scroll. For example, when the displacement y2 (0, a (ΔX ² + ΔY ² ) ^1/2 ) after notification is notified from the displacement adjustment unit 23, the scroll size L is determined by the equation (2), and the scroll direction Is determined to be downward based on the sign a of ΔY. Note that the coefficient α multiplied by the distance from the start point to the end point of the displacement is 1 in this embodiment, but other positive numerical values, for example, 2/3 may be used. However, the value of α is set so that L is larger than ΔY.

L = (ΔX ² + ΔY ² ) ^1/2 × α (2)
[Processing related to scrolling smartphone 1]
The process regarding the scroll of the smart phone 1 is demonstrated based on FIG. FIG. 2 is a flowchart illustrating an example of processing executed by the smartphone 1 according to the first embodiment.

  First, the display information acquisition unit 26 acquires display information (S1), and converts the display information into an image. The display information acquisition unit 26 outputs the converted image to the scroll control unit 24. The scroll control unit 24 displays the image on the display unit 12.

  Subsequently, the effective direction determination unit 25 determines whether or not the effective direction is determined in the Y-axis direction based on the meta information included in the display information acquired by the display information acquisition unit 26 (S2). If the effective direction is not defined in the Y-axis direction (NO in S2), the process ends.

  On the other hand, when the effective direction is determined in the Y-axis direction (YES in S2), the effective direction determination unit 25 notifies the displacement adjustment unit 23 that the effective direction is the Y-axis direction. Then, the displacement adjustment unit 23 outputs the value of the effective direction (Y-axis direction in this case) component of the operation displacement output from the displacement calculation unit 22 and a predetermined threshold for determining whether or not a drag operation has been performed. Are compared to determine whether a drag operation has been performed (S3). If it is determined that a drag operation has not been performed (NO in S3), the process ends.

  On the other hand, when it is determined that a drag operation has been performed (YES in S3), the displacement adjustment unit 23 determines the scroll direction based on the sign of the Y component ΔY of the operation displacement output from the displacement calculation unit 22 ( S4). For example, when the operation is a drag in the upper right direction, ΔY takes a negative value. In this case, the scroll direction is determined upward based on the fact that ΔY is a negative value. Subsequently, if the operation displacement calculated by the displacement calculation unit 22 includes a component in a direction different from the effective direction (in this example, the X-axis direction component), the displacement adjustment unit 23 determines the scrolling determined in S4. The operation displacement calculated by the displacement calculation unit 22 is converted so as to have the magnitude of the operation displacement in the direction (S5), and the converted displacement is notified to the scroll control unit 24. The scroll control unit 24 scrolls the display image (the object that is the target of the scroll process) based on the converted displacement that has received the notification (S6).

  If the operation displacement calculated by the displacement calculation unit 22 does not include a component in a direction different from the effective direction (in this example, the X-axis direction component), conversion is not necessary. Therefore, in this case, the process of S5 is omitted, and the scroll control unit 24 performs the process according to the operation displacement output by the displacement calculation unit 22 (the operation displacement that is not adjusted by the displacement adjustment unit 23).

  In addition, when an object for which the effective direction is not defined is displayed, and NO is determined in S2, the operation displacement output by the displacement calculation unit 22 (the operation displacement that the displacement adjustment unit 23 has not adjusted) ). For example, when an image that can be scrolled in all directions is displayed and the displacement calculator 22 outputs an operation displacement (ΔX, ΔY), the image is scrolled by ΔX in the X-axis direction and ΔY in the Y-axis direction. Let

  In the above description, the scroll amount corresponding to the displacement amount output from the displacement adjustment unit 23 is shown. However, based on the displacement amount output from the displacement adjustment unit 23, it is determined whether a drag operation has been performed. May be. That is, when the drag operation becomes a direction different from the effective direction, the displacement amount in the direction may be compared with the threshold value as the displacement amount in the effective direction to determine whether or not the drag operation has been performed. Accordingly, since the operation is performed in a direction different from the effective direction, it can be determined that the drag operation has been performed as intended by the user even when the effective direction component of the operation displacement is shortened.

  With the above processing, when the effective scrolling direction is determined in the uniaxial direction, the display image is scrolled according to the amount of displacement of the input position. Thereby, even when an operation in a direction different from the effective direction of scrolling is performed, it is possible to perform scrolling according to the size of the operation (amount of displacement in the oblique direction).

  Further, by the above processing, an operation according to the effective direction component of the displacement of the input position and the amount of displacement of the input position is performed. For example, when the effective direction is the Y-axis direction and an operation is performed in the upper right direction, the same operation as that performed when the operation is performed in the upward direction is performed. Thereby, an operation reflecting the direction of the operation can be performed.

[Modification]
The smartphone 1 may include a one-hand operation determination unit (one-hand operation determination unit) that determines whether the holding and operation are performed with one hand. In this case, when the one-hand operation determination unit determines that the holding and operation is performed with one hand, and the effective direction determination unit 25 determines that the effective direction is determined as the uniaxial direction, the displacement adjustment unit 23 The direction and amount of the scroll are determined based on the displacement after being converted by. The determination as to whether holding and operation is performed with one hand may be performed using an output from a contact sensor or the like provided in the smartphone 1.

  Advantages of this modification will be described with reference to FIG. FIG. 3 is a diagram illustrating an operation example of the smartphone 1. In general, when using a mobile terminal with one hand, the left and right ends of the mobile terminal are firmly sandwiched between the base part of the thumb of the palm (the thumb adductor muscle) and the first indirect of the little finger, ring finger, middle finger, and index finger. So often hold. In this case, the palm and the little finger to the index finger are closed to hold the terminal, and the root of the thumb is also restricted to hold the terminal, so that only the vicinity of the fingertip of the thumb is free. Therefore, as shown in FIG. 3A, when the user performs an operation with the intention of showing the operation displacement d1 in the upward direction, as shown in FIG. In many cases, an operation displacement such as an operation displacement d2 is indicated. That is, the accuracy related to the user's operation direction is reduced.

  According to the configuration of the above modification, the operation displacement is converted when the accuracy with respect to the user's operation direction is reduced, so that the conversion execution timing can be narrowed down to a situation where conversion is highly necessary.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIGS. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted. FIG. 5 is a block diagram of the smartphone 1A according to the second embodiment.

  As shown in FIG. 5, the smartphone 1 </ b> A according to the present embodiment is different from the smartphone 1 according to the first embodiment in that a controller 20 </ b> A is provided instead of the controller 20. The control unit 20A is different from the control unit 20 in that the operation speed of the flick operation is calculated and scroll processing is performed. The control unit 20A includes a speed adjusting unit 23A instead of the displacement adjusting unit 23, and further includes a speed calculating unit 27.

  The speed calculation unit 27 calculates an operation speed that is a displacement amount of the input position per unit time in a period from the start to the end of the touch based on the operation displacement calculated by the displacement calculation unit 22. The speed calculation unit 27 outputs the calculated operation speed to the speed adjustment unit 23A.

The speed adjustment unit 23A determines whether or not a flick operation has been performed. Specifically, the operation speed output from the speed calculation unit 27 is compared with a predetermined threshold value for determining whether or not the flick operation has been performed, and if it is equal to or greater than the threshold value, it is determined that the flick operation has been performed. To do. Further, the speed adjustment unit 23A determines that the flick operation has been performed when the effective direction determination unit 25 determines that the effective direction is determined as a uniaxial direction (for example, the Y-axis direction), and When the operation direction is different from the effective direction, the operation speed is adjusted. Specifically, the magnitude of the operation speed is set to the magnitude of the speed in the Y-axis direction, and the magnitude of the speed in the X-axis direction is set to zero and notified to the scroll control unit 24. For example, in the example of FIG. 4B, when the operation displacement d3 is detected during the sampling time Δt, the speed adjustment unit 23A determines the operation speed calculated by the speed calculation unit 27: (ΔX / Δt, ΔY / Displacement y2 converted from (Δt): (0, a (ΔX ² + ΔY ² ) ^1/2 / Δt) is notified to the scroll control unit 24. Note that a indicates the direction of the operation displacement in the effective direction (equal to the direction of the operation speed). In this example, if ΔY is positive, a = 1, and if negative, a = -1.

  The scroll control unit 24 determines an initial speed for scrolling the image output from the display information acquisition unit 26. Specifically, when the effective direction determination unit 25 determines that the effective direction is only the Y-axis direction, that is, when the scrollable direction is only the Y-axis direction, the conversion notified by the speed adjustment unit 23A. Based on the later speed, the scroll control unit 24 determines the initial speed of scrolling. Further, the scroll control unit 24 decelerates the scroll speed by a constant acceleration after the start of scrolling. Thus, the scroll amount is proportional to the initial scroll speed. That is, the scroll amount is proportional to the speed after conversion by the speed adjusting unit 23A.

  Then, the process which the smart phone 1A which concerns on this embodiment performs is demonstrated based on FIG. FIG. 6 is a flowchart illustrating an example of a process executed by the smartphone 1A according to the second embodiment. The process in the smartphone 1A is different from the process in the smartphone 1 shown in FIG. 2 in that the processes shown in S3A, S5A, and S6A are performed in place of the processes shown in S3, S5, and S6. Then, it explains focusing on these differences.

  When the effective direction is determined in the Y-axis direction (YES in S2), the effective direction determination unit 25 notifies the displacement adjustment unit 23 that the effective direction is the Y-axis direction. Then, the speed adjustment unit 23A has a value of an effective direction (Y-axis direction here) component of the operation speed output from the speed calculation unit 27, and a predetermined threshold for determining whether or not a flick operation has been performed. Are compared to determine whether or not a flick operation has been performed (S3A). If it is determined that a flick operation has not been performed (NO in S3A), the process ends.

  On the other hand, when it is determined that the flick operation has been performed (YES in S3A), the speed adjustment unit 23A is based on the sign of the Y component of the operation speed output from the speed calculation part 27, that is, the sign of the Y component ΔY of the operation displacement. Thus, the speed adjusting unit 23A determines the direction of scrolling (S4). Subsequently, if the operation speed calculated by the speed calculation unit 27 includes a component in a direction different from the effective direction (in this example, the X-axis direction component), the speed adjustment unit 23A determines the scrolling determined in S4. The operation speed calculated by the speed calculation unit 27 is converted so as to have the magnitude of the operation speed in the direction (S5A), and the converted speed is notified to the scroll control unit 24. The scroll control unit 24 scrolls the display image based on the converted speed received the notification (S6A).

  If the operation speed calculated by the speed calculation unit 27 does not include a component in a direction different from the effective direction (in this example, the X-axis direction component), conversion is unnecessary. Therefore, in this case, the process of S5A is omitted, and the scroll control unit 24 performs the process according to the operation speed output from the speed calculation unit 27 (the operation speed that is not adjusted by the speed adjustment unit 23A).

  In addition, when an object for which the effective direction is not defined is displayed, and it is determined NO in S2, the operation speed output by the speed calculation unit 27 (the operation speed that is not adjusted by the speed adjustment unit 23A) ). For example, when an image that can be scrolled in all directions is displayed and the speed calculation unit 27 outputs the operation speed (ΔX / Δt, ΔY / Δt), the speed component in the X-axis direction is ΔX / Δt, Y The image is scrolled so that the velocity component in the axial direction becomes ΔY / Δt.

  In the above description, the scroll amount corresponding to the speed output from the speed adjustment unit 23A is shown. However, even if it is determined whether the flick operation is performed based on the speed output from the speed adjustment unit 23A. Good. That is, when the flick operation becomes a direction different from the effective direction, the operation speed in the direction may be compared with the threshold value as the operation speed in the effective direction to determine whether or not the flick operation has been performed. Thus, since the operation is performed in a direction different from the effective direction, it can be determined that the flick operation has been performed as intended by the user even when the effective direction component of the operation speed is shortened.

  According to the above configuration, when the displacement component of the input position in the direction orthogonal to the effective direction does not affect the operation, it is calculated from the displacement having a magnitude corresponding to the amount of displacement of the input position in the effective direction. The operation is determined based on the operation speed. Thereby, even when the direction of the operation speed is not the effective direction, the scroll amount is determined according to the magnitude of the speed. That is, it is possible to perform scrolling according to the magnitude of the speed indicated by the user in the operation.

[Modification]
In the process shown in S5A in the second embodiment, the scroll deceleration coefficient may be decreased according to the magnitude of the operation speed (or operation displacement). The deceleration coefficient is an acceleration in the direction of decelerating the scroll, that is, an acceleration in the direction opposite to the scroll direction, and is a negative value when the scroll speed is expressed as a positive value. For example, it is conceivable to change the deceleration coefficient as in the following equation (3). In the following formula (3), since the value of the deceleration coefficient (friction) is inversely proportional to the amount of operation displacement ((ΔX ² + ΔY ² ) ^1/2 ), the smaller the amount of operation displacement, the smaller the deceleration coefficient. Is set. Since the scroll amount becomes larger as the deceleration coefficient is smaller, scrolling by an amount corresponding to the magnitude of the operation displacement amount is realized by using Equation (3).

friction = original_friction / (ΔX ² + ΔY ² ) ^1/2 (3)
(Original_friction: initial value of deceleration coefficient, friction: deceleration coefficient)
(A) of FIG. 7 represents the change of the speed of the scroll based on the flick operation in the smartphone 1A according to the second embodiment. As shown in the figure, the speed V1 becomes the speed V2 after a predetermined time elapses, and further becomes the speed V3 after the predetermined time elapses. Since the deceleration coefficient is constant, the displacement amount of the speed when the same predetermined time elapses is the same. FIG. 7B shows the change in the scroll speed based on the flick when the scroll deceleration coefficient is decreased in accordance with the amount of operation displacement in the process shown in S5A. As shown in the figure, the speed V4 becomes the speed V5 after the elapse of a predetermined time, and further becomes the speed V6 after the elapse of the predetermined time. Decreasing the deceleration factor slows down the speed reduction. That is, also in the configuration of this modification, the screen can be scrolled by an amount corresponding to the magnitude of the operation speed, as in the example of the second embodiment.

  In each of the above embodiments, the axial direction to be determined by the effective direction determination unit 25 is not limited to the Y-axis direction. For example, the effective direction determination unit 25 may determine whether or not the effective direction is only the X-axis direction. In this case, if scrolling is possible only in the left-right direction, it is determined that the effective direction is only one axial direction in the X-axis direction, and the scroll processing is performed assuming that the input position is displaced by the amount of operation displacement and in the X-axis direction. Done.

  In each of the above-described embodiments, an example in which the displacement of the input position is detected by the touch panel 10 has been described. However, the input position may be detected by a three-dimensional touch sensor that can detect an operation on at least three orthogonal axes. According to this configuration, there is no input surface that contacts a finger, a stylus, or the like, and it is difficult to move the input position parallel to the axis that is the target of the operation determination. Even in the case of tilting with respect to the axis, the processing can be determined according to the displacement amount of the input position.

  In each of the above-described embodiments, description has been made taking an example of image scrolling by dragging or flicking operation, but the processing performed based on the displacement of the input position is not limited to these examples. For example, the process performed based on the displacement of the input position may be a page feed process for an object composed of a plurality of pages. In this case, when the page turning operation (for example, dragging or flicking) is in a direction different from the effective direction, it is determined whether the page turning operation is performed with the displacement amount in the direction as the displacement amount in the effective direction. . Therefore, since the operation is performed in a direction different from the effective direction, the page turning process is performed as intended by the user even when the effective direction component of the operation displacement is shortened. In this case, the object to be processed is an object whose page is switched. In addition to this, when increasing or decreasing parameters such as output volume or display brightness according to the amount of displacement of the input position in the effective direction, if the input position is displaced obliquely relative to the effective direction, the amount of displacement is The present invention can be applied to various operations in which the effective direction is predetermined, for example, the displacement amount in the effective direction. In this case, a slider for increasing / decreasing parameters is an object to be processed.

  In each of the above embodiments, the case where the Y-axis direction is the effective direction has been described as an example, but the case where the effective direction is the X-axis direction or another axial direction is also included in the scope of the present invention. For example, the effective direction may be a direction along an oblique axis that is not orthogonal to either the X axis or the Y axis.

[Embodiment 3]

  In the latter case, the smartphones 1 and 1A include a CPU that executes instructions of a program that is software that realizes each function, and a ROM (Read Only Memory) in which the program and various data are recorded so as to be readable by the computer (or CPU).

[Summary]
The information processing apparatus (smartphone 1, 1A) according to aspect 1 of the present invention performs an information processing apparatus that performs a predetermined process on an object that is a target of the process, according to the amount and direction of displacement of the input position. An effective direction determination means (effective direction determination unit 25) for determining, based on the object, whether or not an effective direction that is the direction of the displacement for executing the processing is determined as a uniaxial direction; When the input position is displaced in a direction different from the effective direction, and the effective direction determination unit determines that the effective direction is determined as a uniaxial direction, the amount of the displacement is calculated. Displacement adjusting means (displacement adjusting unit 23) for providing an amount of displacement in the effective direction is provided.

  According to the above configuration, when an object whose effective direction is a uniaxial direction is a processing target, processing is performed according to the amount of displacement of the input position. As a result, even if an operation in a direction different from the direction (effective direction) that is the target of the process determination is performed, it is possible to perform a process according to the amount of displacement of the input position.

  Note that the object is not particularly limited as long as it is a target to be processed in advance according to the amount and direction of displacement of the input position. For example, an image scrolled according to the amount and direction of displacement of the input position (the entire image displayed on the display screen or a part thereof) may be the object. May be. Further, for example, the object for which page switching is performed according to the amount and direction of displacement of the input position may be the object. Furthermore, for example, the object may be a slider or the like to be displayed in order to increase or decrease parameters such as output volume or display luminance according to the amount and direction of displacement of the input position. Whether or not the effective direction is determined in the uniaxial direction may be determined by a method corresponding to the object. For example, if the image to be scrolled is the above object, the display width matches the display width of the display device that displays the image by referring to the information indicating the setting of the display width of the image. When it is determined, the effective direction may be determined as being uniaxial. This is because in such a case, scrolling in the width direction is not performed. Also, if the effective direction is an object such as a page-switching object or a slider for changing parameters, the effective direction is set to one axis direction by referring to the information defining the effective direction. You can judge whether it is defined.

  In the information processing device according to aspect 2 of the present invention, in the aspect 1, the effective direction is defined as a positive direction along the direction and a negative direction opposite to the positive direction. And the displacement adjusting means is configured to apply the positive direction or the negative direction of the effective direction according to whether the effective direction component of the displacement of the input position is a positive value or a negative value. It may be specified whether the input position is displaced.

  According to the above configuration, depending on whether the effective direction component of the displacement of the input position is a positive value or a negative value, the input position is in a positive direction or a negative direction of the effective direction. Since it is specified whether it has been displaced, an operation according to the direction of displacement of the input position is performed. Thereby, processing reflecting the direction of operation can be performed.

  In the information processing apparatus (smart phone 1A) according to aspect 3 of the present invention, in the aspect 1 or 2, the displacement adjustment unit (speed adjustment unit 23A) determines the displacement amount of the input position in the effective direction. In addition, the speed at which the input position is displaced is calculated from the amount of displacement, and the predetermined process may be performed at least according to the calculated speed.

  According to the above configuration, when the displacement component of the input position in the direction orthogonal to the effective direction does not affect the operation, it is calculated from the displacement having a magnitude corresponding to the amount of displacement of the input position in the effective direction. The action is determined based on the determined speed. Thereby, even when the direction of the operation speed is not the effective direction, the process is performed according to the magnitude of the speed. That is, processing according to the magnitude of the speed indicated by the user in the operation can be performed.

  The information processing apparatus according to aspect 4 of the present invention is the information processing apparatus according to aspects 1 to 3, wherein the object is an image that can be scroll-displayed on a display screen, and the predetermined process is performed by the displacement adjustment unit. Processing for scrolling the image in the effective direction by an amount corresponding to the determined amount of displacement may be performed.

  According to the above configuration, when the input position is displaced in a direction different from the effective direction, the effective direction determination unit determines that the effective direction is determined as a uniaxial direction. The amount of scrolling is determined according to the amount of displacement of the input position. Thereby, even if the displacement of the user's input position is in a direction different from the effective direction, it is determined to scroll according to the amount of the displacement. That is, it is possible to scroll according to the size of the operation by the user. Note that the scrolled image (object) may be the entire image displayed on the display screen or a part thereof as described above. For example, it may be an image in a window pop-up displayed on the browsing screen or an image displayed in a frame (such as an inline frame) obtained by dividing one page.

  An information processing apparatus according to aspect 5 of the present invention further includes a one-hand operation determination unit that determines whether or not the information processing apparatus is held and operated by one hand in the above-described aspects 1 to 4, wherein the input position is Detected by an operation by touching a finger of a user holding the information processing apparatus, and the one-handed operation determining unit detects when the input position is displaced in a direction different from the effective direction. When it is determined that the holding and operation are performed with one hand, and the effective direction determining means determines that the effective direction is determined as a uniaxial direction, the effective direction is determined to be different from the effective direction. When the input position is displaced, the amount of displacement may be the amount of displacement in the effective direction.

  According to said structure, operation | movement is determined according to the amount of said displacement, only when holding and operation are performed with one hand. In general, when the holding and the touch panel are operated with one hand, the accuracy regarding the operation direction of the user is particularly lowered. That is, since the operation displacement is converted when the accuracy with respect to the user's operation direction is reduced, the conversion execution timing can be narrowed down to a situation where conversion is highly necessary.

  The information processing apparatus according to each aspect of the present invention may be realized by a computer. In this case, the information processing apparatus is realized by the computer by causing the computer to operate as each unit included in the information processing apparatus. A control program for the information processing apparatus and a computer-readable recording medium on which the control program is recorded also fall within the scope of the present invention.
