Hereinafter, some embodiments according to the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol was attached | subjected to the corresponding element in several drawing.
In an information processing apparatus including a touch panel such as a smartphone, a personal computer, a tablet PC, a PDA, or an electronic dictionary, an operation instruction is often input to the information processing apparatus via the touch panel. In this case, an operation instruction is input by bringing a detection target such as a user's fingertip into contact with the touch panel, which can detect the contact with the touch panel. When the user wants to move the display area of the content being displayed to another area of the content without changing the display magnification, a scroll operation is often executed. In some examples, the scroll operation instruction is input by moving the detection target object in one direction while being in contact with the touch panel. In scrolling, for example, when the object to be detected is moved upward in contact with the touch panel and scrolled upward in the display screen, the display area is displayed so that the lower area of the content is displayed in the display area. Move to content.

  In scrolling, the scroll amount indicating the distance to move the display area with respect to the content, and the scroll speed indicating the moving speed of the display area are, in some examples, the speed of the detection object when the detection object leaves the touch panel. Is set in proportion to For example, in such an information processing apparatus, when the user wants to scroll the content over a wider range by inputting a single operation instruction, the object to be detected is moved at high speed on the touch panel and scrolling is performed at a high scroll speed. There must be. However, when the scroll speed is fast, it becomes difficult to visually recognize the contents of the displayed contents such as characters and icons during scrolling. Alternatively, in order to perform scrolling while maintaining the visibility of the content, the scrolling speed must be slowed down. In this case, the scroll range is narrowed by inputting a scroll operation instruction once. Therefore, it is necessary to repeat the scroll operation instruction a plurality of times. Such a decrease in visibility or the necessity of repeated input of a scroll operation instruction that occurs when the display area is scrolled over a wide range of content contributes to a decrease in usability of the information processing apparatus. .

  Therefore, in some embodiments, the scroll amount of the display area that is moved by the input of the scroll operation instruction is changed according to the number of contact points where the touch panel and the detection target object are in contact. FIG. 1 shows a process of changing the scroll amount of the display area 4 during scrolling according to the number of contacts 12 between the touch panel 2 and the detection object 10 executed by the information processing apparatus 1 according to some embodiments. It is a figure explaining.

  FIG. 1 a illustrates an information processing apparatus 1 such as a smartphone, a personal computer, a tablet PC, a PDA, and an electronic dictionary. The information processing apparatus 1 can perform multi-touch (multi-point detection of two or more points). A touch panel 2 is provided. The touch panel 2 detects, for example, the contact of the detection target 10 such as a fingertip and receives an operation instruction input by the contact.

  Further, the input operation of the two operation instructions (1) and (2) is illustrated as an input of the scroll operation instruction. The operation instruction (1) shows an example in which one fingertip 11 is brought into contact with the touch panel 2 as the detection object 10 and a scroll operation instruction is input. The contact point 12 between the fingertip 11 and the touch panel 2 is one. Are shown. Further, the contact 12 is provided with an arrow 13 indicating the speed and direction of the detection target 10 when the fingertip 11 is separated from the touch panel 2 when inputting an operation instruction. The direction of the arrow 13 represents the direction in which the fingertip 11 is moved on the touch panel 2, and the size of the arrow 13 represents the speed of the detection target 10 when the fingertip 11 moves away from the touch panel 2. On the other hand, the operation instruction (2) shows an example of inputting a scroll operation instruction by bringing the two fingertips 11 into contact with the touch panel 2 as the detection target 10, and the fingertip 11 and the touch panel 2 at that time are input. Two contacts 12 are shown. Each contact 12 is provided with an arrow 13 indicating the speed and direction of the detection object 10 when the fingertip 11 is separated from the touch panel 2 in inputting an operation instruction.

  As described above, the operation instruction (1) and the operation instruction (2) differ in the number of fingertips 11 used for inputting the scroll operation instruction, that is, in the number of contacts 12. However, the size and direction of the arrow 13 indicating the speed and direction of the detection target 10 when the fingertip 11 leaves the touch panel 2 are substantially the same direction and size in the operation instruction (1) and the operation instruction (2). ing. Therefore, the scroll direction and speed in the scroll operation instruction input by the operation instruction (1) and the operation instruction (2) are set to substantially the same direction and speed. However, as will be described with reference to FIG. 1b, in some embodiments, in the operation instruction (1) and the operation instruction (2), the scrolling of the display area 4 that moves in the scroll according to the number of the contacts 12 is performed. The amount is different.

  FIG. 1 b shows that the display area 4 (4-1 to 4-3) is displayed in the content 3 when the scroll operation instruction is input by inputting the two operation instructions (1) and (2) described in FIG. It is a figure explaining the scroll amount which shows the distance which moves with respect. As shown in FIG. 1b, when a scroll operation instruction is input at one contact 12 of the operation instruction (1), the display area 4 moves from the display area 4-1 to the display area 4-2. On the other hand, when a scroll operation instruction is input at the two contact points 12 of the operation instruction (2), the display area 4 moves from the display area 4-1 to the display area 4-3, and the operation instruction (1) Compared to the case, it is scrolled at a longer distance.

  As described above, in some embodiments, when the user inputs a scroll operation instruction, the distance by which the display area 4 moves with respect to the content 3 is changed by changing the number of the contacts 12 with respect to the touch panel 2. The amount of scrolling represented can be changed. Therefore, in order to scroll the display area 4 over a wider range of the content 3, for example, the user only has to increase the number of contacts 12 and input a scroll operation instruction, and there is no need to increase the scroll speed. Therefore, the user can scroll the display area 4 over a longer distance while maintaining visibility. Alternatively, in order to scroll the display area 4 over a long distance, the user does not need to repeatedly input a scroll operation instruction multiple times. Therefore, the usability of the information processing apparatus 1 is improved.

  FIG. 2 is a diagram illustrating a functional block configuration of the information processing apparatus 1 according to some embodiments. The information processing apparatus 1 includes a control unit 200 and a storage unit 220, for example. The control unit 200 includes functional units 210 such as a counting unit 211, a determination unit 212, a determination unit 213, a calculation unit 214, a change unit 215, a first attenuation amount calculation unit 216, and a second attenuation amount calculation unit 217, for example. Yes. The storage unit 220 of the information processing apparatus 1 stores, for example, a program 221 and information 222 such as scroll amount change information 300, attenuation amount change information 600, and viscous friction coefficient change information 900 described later. The control unit 200 of the information processing apparatus 1 reads and executes the program 221 to, for example, the counting unit 211, the determination unit 212, the determination unit 213, the calculation unit 214, the change unit 215, the first attenuation amount calculation unit 216, and the first 2 functions as a functional unit 210 such as an attenuation calculation unit 217. Details of each functional unit 210 and information 222 stored in the storage unit 220 will be described later.

  Hereinafter, a process of changing the scroll amount of the display area 4 according to the number of the contacts 12 according to the first embodiment will be described with reference to FIGS. 3 to 5. In the following description, the scroll amount is, for example, an amount representing a distance by which the display area is moved with respect to the content in scrolling. In other words, the scroll amount is, for example, a value representing a moving distance on the content from when the display area 4 starts to move until it stops in scrolling. The scroll speed represents, for example, the moving speed of the display area in scrolling.

  FIG. 3 is a diagram illustrating scroll amount change information 300 according to the first embodiment. In one embodiment, the scroll amount change information 300 is stored in the storage unit 220 of the information processing apparatus 1. The scroll amount change information 300 is information that associates the number of contact points 12 (the number of contact points 301) when a scroll operation instruction is input with a scroll amount coefficient 302 for adjusting the scroll amount. For example, when the number of the contacts 12 when the scroll operation instruction is input is 2, the scroll amount coefficient 302: X2 associated with the number of contacts 301: 2 is acquired from the scroll amount change information 300. The The scroll amount coefficient 302 corresponds to the number of contact points 301, for example, as described below, scrolling is performed with a scroll amount obtained by multiplying the reference first scroll amount by the scroll amount coefficient 302. Is a coefficient for adjusting the scroll amount.

  FIG. 4 is a diagram illustrating a process of changing the scroll amount of the display area 4 according to the number of contacts 12 executed by the control unit 200 of the information processing apparatus 1 according to the first embodiment. The operation flow of the process of changing the scroll amount of the display area 4 in FIG. 4 is implemented, for example, when the control unit 200 reads and executes the program 221 stored in the storage unit 220. In one embodiment, when an operation instruction is input on the touch panel 2 of the information processing apparatus 1, the process of changing the scroll amount of the display area 4 in FIG. 4 starts. In step S401, the control unit 200 counts the number of contacts 12 of the detection target 10 that are in contact with the touch panel 2 when an operation instruction is input. In step S <b> 402, the control unit 200 determines whether the input operation instruction is a scroll operation instruction based on the locus of the contact 12 on the touch panel 2.

  The determination of whether or not the operation instruction is a scroll operation instruction may be performed as follows in one embodiment. For example, when the number of the contacts 12 is one, the locus of the contacts 12 in a predetermined period immediately before the detection target 10 leaves the touch panel 2 may be directed in a substantially uniform direction within a predetermined error range. For example, it may be configured to determine that it is a scroll operation instruction. Further, when there are a plurality of contacts 12 between the detection object 10 and the touch panel 2, the trajectories of the arrows 13 of the plurality of contacts 12 are all moving in substantially the same direction within a predetermined error range. Further, it may be configured to determine that the instruction is a scroll operation instruction. FIG. 5 shows an example of determining an operation instruction when there are a plurality of contacts 12.

  FIG. 5 is a diagram illustrating determination of an operation instruction when there are a plurality of contacts 12 according to an embodiment. On the touch panel 2 of the information processing apparatus 1 in FIG. 5, a fingertip 11 is shown as the detection object 10, and a contact 12 between the fingertip 11 and the touch panel 2 is shown. Furthermore, an arrow indicating the locus 15 of the detection target 10 in a predetermined period immediately before the fingertip 11 is separated from the touch panel 2 is shown.

  The determination as to whether or not the operation instruction is a scroll when there are a plurality of contacts 12 is, for example, whether or not the trajectory 15 is moving in the same direction approximately uniformly within a predetermined error range at each of the contacts 12. To do. Then, in each of the contacts 12, when the trajectory 15 moves in the same direction approximately uniformly within a predetermined error range, the directions of the trajectories 15 are compared. For example, it is determined whether or not an angle α formed by the direction of the locus 15 of one contact 12 out of the plurality of contacts 12 is within a predetermined angle with respect to the direction of the locus 15 of the other contact 12. To do. When the angle α formed by the direction of the locus 15 of one contact 12 and the direction of the locus 15 of the other contact 12 falls within a predetermined angle, it is determined that a scroll operation instruction has been input. May be. In the embodiment, the predetermined error range and the predetermined angle are set to values that can separate operations other than scrolling such as pinch-out and pinch-in from scroll operations. .

  For the process of determining whether or not the operation instruction when the number of the contacts 12 is one is scrolling, for example, determination used in an existing smartphone or the like may be used. For example, in an existing smartphone, in accordance with an operation instruction input to the touch panel 2, a process for separating an operation instruction other than scrolling such as pinch-out and pinch-in from an operation instruction for scroll input from one contact 12 There is something that has done. The separation processing of these existing operation instructions may be used for the process of determining whether or not the operation instruction when the number of contacts 12 is one is a scroll operation instruction.

  Furthermore, for the input of the scroll operation instruction when there are a plurality of contacts 12, the determination executed by an existing smartphone or the like when the number of contacts 12 is one may be used. . In this case, for example, by adding the determination as to whether or not the orientations of the trajectories 15 of the plurality of contacts 12 are approximately in the same direction to the determination used by an existing smartphone or the like, An input of a scroll operation instruction by the contact 12 may be determined.

  For example, as described above, it is determined in step S402 in FIG. 4 whether or not the input operation instruction is scroll. If the input operation instruction is not scrolling (No in step S402), the operation flow ends. On the other hand, if the input operation instruction is scrolling (Yes in step S402), the flow proceeds to step S403.

  In step S403, the control unit 200 determines an initial speed for moving the display area 4 with respect to the content 3 in scrolling. In one embodiment, the initial scroll speed is determined according to the movement speed of the locus of the contact 12 in a predetermined period immediately before the contact 12 leaves the touch panel 2 when an operation instruction determined to be scroll is input. For example, the initial speed may be determined in proportion to the moving speed of the contact 12 in a predetermined period immediately before the detection target 10 is separated from the touch panel 2. The moving speed of the contact point 12 represents the moving speed of the detection target object 10 when the detection target object 10 is separated from the touch panel 2, for example.

  Subsequently, in step S404, the control unit 200 calculates a first scroll amount based on the calculated initial speed. The first scroll amount is a scroll amount used as a reference in the subsequent processing from step S405 to step S407.

  In step S405, the control unit 200 refers to the scroll amount change information 300, and acquires the scroll amount coefficient 302 associated with the contact number 301 having the number of contacts 12 counted in step S401. In step S406, the control unit 200 multiplies the acquired scroll amount coefficient 302 by the first scroll amount calculated in step S404, thereby changing the scroll amount representing the distance from when the display area 4 starts to move until it stops. To do. In step S407, the control unit 200 executes scrolling on the display screen of the touch panel 2 so that the display area 4 is scrolled with respect to the content 3 by the distance of the scroll amount obtained by the change in step S406. The operation flow ends.

  As described above, in the operation flow of FIG. 4, the scroll amount coefficient 302 is acquired from the scroll amount change information 300 according to the number of the contacts 12. Then, the scroll amount representing the distance from when the display area 4 starts to move until it stops is changed by multiplying the obtained first scroll amount by the obtained scroll amount coefficient 302 based on the first scroll amount determined based on the initial speed. The The display area 4 is scrolled with respect to the content 3 using the scroll amount changed according to the number of the contacts 12. Therefore, the user can change the amount of scroll by which the display area 4 is moved with respect to the content 3 by changing the number of the contacts 12 to be brought into contact with the touch panel 2 when inputting the scroll operation instruction. Become.

  Further, for example, by associating one or more different values as the scroll amount coefficient 302 with each of the contact numbers 301 included in the scroll amount change information 300, the scroll amount can be increased according to the number of the contacts 12.

  For example, the scroll amount coefficient 302: 1.0 for the contact number 301: 1, the scroll amount coefficient 302: 1.5 for the contact number 301: 2, and the scroll amount coefficient 302: for the contact number 301: 3. 2.0 is associated with the scroll amount change information 300. In this case, for example, when the user inputs a scroll operation instruction with one finger, the first scroll amount is multiplied by the scroll amount coefficient 302: 1.0 associated with the contact number 301: 1. It is done. Since the scroll amount obtained as a result is the same as the first scroll amount, the scroll is executed so that the display area 4 moves by the first scroll amount.

  For example, when a scroll operation instruction is input with two fingers, the first scroll amount is multiplied by the scroll amount coefficient 302: 1.5 associated with the contact number 301: 2. Therefore, scrolling is executed so that the display area 4 moves relative to the content 3 with a scroll amount that is 1.5 times larger than the first scroll amount. Therefore, in order to scroll the display area 4 over a wider range of the content 3, the user only has to input the scroll operation instruction by increasing the number of the contacts 12, and the moving speed of the contact 12 at the time of the scroll operation instruction That is, there is no need to increase the scrolling speed. Therefore, it is possible to scroll the display area 4 over a longer distance while maintaining the visibility of the content 3. Alternatively, in order to scroll the display area 4 over a longer distance, the user does not need to repeat the scroll operation instruction multiple times. Therefore, the usability of the information processing apparatus 1 is improved.

  In the operation flow of FIG. 4, in the process of step S <b> 401, the control unit 200 of the information processing apparatus 1 functions as the counting unit 211. In the process of step S <b> 402, the control unit 200 of the information processing apparatus 1 functions as the determination unit 212. In the process of step S403, the control unit 200 of the information processing apparatus 1 functions as the determination unit 213. In the process of step S404, the control unit 200 of the information processing apparatus 1 functions as the calculation unit 214. In the processing from step S405 to step S407, the control unit 200 of the information processing apparatus 1 functions as the changing unit 215.

  Subsequently, a process of changing the scroll amount of the display area 4 according to the number of the contacts 12 according to the second embodiment will be described with reference to FIGS. In the second embodiment, the amount of scroll representing the distance from when the display area 4 starts to move until it stops is changed by changing the amount of attenuation, which is the amount by which the scroll speed is attenuated, according to the number of contacts 12. The

  FIG. 6 is a diagram illustrating attenuation amount change information 600 according to the second embodiment. In one embodiment, the attenuation amount change information 600 is stored in the storage unit 220 of the information processing apparatus 1. The attenuation amount change information 600 includes the number of contacts 12 (contact number 601) when a scroll operation instruction is input, and an attenuation coefficient 602 for changing the scroll amount by adjusting the attenuation amount of the scroll speed. Is information that associates. For example, when the number of the contacts 12 when the scroll operation instruction is input is 2, the attenuation coefficient 602: Y2 associated with the contact number 601: 2 is acquired from the attenuation change information 600. The The attenuation coefficient 602 is information that is multiplied by the first attenuation that is a reference in order to obtain a second attenuation that is an amount that actually attenuates the scroll speed, as described below, for example. .

  FIG. 7 is a diagram illustrating a process of changing the scroll amount of the display area 4 according to the number of contacts 12 executed by the control unit 200 of the information processing apparatus 1 according to the second embodiment. The operation flow of the process of changing the scroll amount of the display area 4 in FIG. 7 is implemented, for example, when the control unit 200 reads and executes the program 221 stored in the storage unit 220. In one embodiment, when an operation instruction is input on the touch panel 2 of the information processing apparatus 1, the process of changing the scroll amount of the display area 4 in FIG. 7 is started. In step S <b> 701, the control unit 200 counts the number of contacts 12 of the detection target 10 that are in contact with the touch panel 2 when an operation instruction is input. In step S <b> 702, the control unit 200 determines whether or not the input operation instruction is a scroll operation instruction based on the locus of the contact 12 on the touch panel 2. The determination of whether or not this is a scroll operation instruction may be performed, for example, as described with reference to step S402 and FIG.

  In step S702, when the input operation instruction is not scrolling (No in step S702), the operation flow ends. On the other hand, when the input operation instruction is scrolling (Yes in step S702), the flow proceeds to step S703. In step S <b> 703, the control unit 200 determines the initial scroll speed for moving the display area 4 with respect to the content 3 in scrolling. In one embodiment, the initial scroll speed is determined according to the movement speed of the locus of the contact 12 in a predetermined period immediately before the contact 12 leaves the touch panel 2 when an operation instruction determined to be scroll is input. For example, the initial speed may be determined in proportion to the moving speed of the contact 12 in a predetermined period immediately before the detection target object 10 leaves the touch panel 2. The moving speed of the contact point 12 represents the moving speed of the detection target object 10 when the detection target object 10 is separated from the touch panel 2, for example.

  Subsequently, in step S704, the control unit 200 calculates a first attenuation amount by a predetermined function using the calculated initial speed. The first attenuation amount calculated based on the initial speed in step S704 is used as a reference in the subsequent processing from step S705 to step S707. The attenuation amount is a value that represents the amount by which the scroll speed is attenuated and slowed down. In step S705, the control unit 200 refers to the attenuation amount change information 600, and acquires the attenuation amount coefficient 602 associated with the contact number 601 corresponding to the number of contacts 12 counted in step S701. In step S706, the control unit 200 obtains the second attenuation amount by multiplying the acquired attenuation amount coefficient 602 by the first attenuation amount calculated in step S704. In step S707, the control unit 200 executes scrolling so that the scroll speed is attenuated from the initial speed by the second attenuation amount obtained in step S706, thereby changing the scroll amount. If the scroll amount is changed by executing scrolling with the second attenuation amount in step S707, the operation flow ends.

  As described above, in the operation flow of FIG. 7, the attenuation coefficient 602 is acquired from the attenuation change information 600 according to the number of the contacts 12. Then, the second attenuation amount is acquired by multiplying the first attenuation amount, which is a reference determined based on the initial speed, by the acquired attenuation amount coefficient 602. Subsequently, the scroll speed is attenuated from the initial speed by the second attenuation amount, thereby changing the scroll amount representing the distance from when the display area 4 starts to move until it stops. In other words, the scroll amount by which the display area 4 is scrolled with respect to the content 3 is changed by changing the attenuation amount of the scroll speed from the initial speed until the scroll speed becomes 0 according to the number of the contacts 12. Therefore, the user can change the scroll amount of the display area 4 by changing the number of the contacts 12 to be brought into contact with the touch panel 2 when inputting the scroll operation instruction.

  Further, for example, by associating different values in the range of 0 to 1 as the attenuation coefficient 602 with each of the contact numbers 601 included in the attenuation amount change information 600, the scroll amount is increased according to the number of the contacts 12. can do.

  For example, the attenuation coefficient 602: 1.0 for the contact number 601: 1, the attenuation coefficient 602: 1/2 for the contact number 601: 2, and the attenuation coefficient 602 for the contact number 601: 3: Assume that 1/3 is associated in the attenuation amount change information 600. In this case, for example, when the user inputs a scroll operation instruction with one finger, the first attenuation amount calculated based on the initial speed is associated with the number of contacts 601: 1. The second attenuation amount is acquired by multiplying the quantity coefficient 602: 1.0. Here, since the resulting second attenuation amount is the same as the first attenuation amount, the control unit 200 executes scrolling so that the scroll speed is attenuated by the first attenuation amount.

  For example, when a scroll operation instruction is input with two fingers, the second attenuation is obtained by multiplying the first attenuation by the attenuation coefficient 602: 1/2 associated with the number of contacts 601: 2. Is obtained. Accordingly, the scrolling is executed so that the scroll speed is attenuated by the second attenuation amount having a value that is 1/2 times smaller than the first attenuation amount. Therefore, when a scroll operation instruction is input with two fingers, the scroll speed is attenuated by the second attenuation amount having a value smaller than the first attenuation amount, and the initial speed is stopped at zero speed. It takes a longer time to attenuate to the time than when it is attenuated by the first attenuation amount. In other words, compared to the case where scrolling is performed with one contact 12, when the scrolling is performed with two contacts 12, the amount of attenuation is small, so the decay rate of the scroll speed from the initial speed is slow, The scroll amount increases.

  Attenuation coefficient 602: 1.0 for the number of contacts 601: 1, attenuation coefficient 602: 1/2 for the number of contacts 601: 2, and attenuation coefficient 602: 1 for the number of contacts 601: 3. FIG. 8 shows the relationship between the scroll speed and the moving distance of the scroll when / 3 is associated. In FIG. 8, the vertical axis indicates the scroll speed, and the horizontal axis indicates the scroll distance. Graph a shows the case where the number of the contacts 12 is one, and the relationship between the speed and the moving distance when the first attenuation is attenuated by the second attenuation obtained by multiplying the attenuation coefficient 602: 1.0. Is shown. The point where the graph a intersects the vertical axis indicates the initial speed when the number of contacts is 601: 1, and the point where the graph a intersects the horizontal axis is the scroll amount when the number of contacts is 601: 1. Graph b shows the case where the number of the contacts 12 is two, and shows the relationship between the speed and the moving distance when the first attenuation is attenuated by the second attenuation obtained by multiplying the attenuation coefficient 602: 1/2. Show. Note that the point where the graph b intersects the vertical axis is the initial speed when the number of contacts is 601: 2, and the point where the graph b intersects the horizontal axis is the scroll amount when the number of contacts is 601: 2. Graph c shows the case where the number of the contacts 12 is three, and shows the relationship between the speed and the moving distance when the first attenuation is attenuated by the second attenuation obtained by multiplying the attenuation coefficient 602: 1/3. Show. The point where the graph c intersects the vertical axis is the initial speed when the number of contacts is 601: 3, and the point where the graph c intersects the horizontal axis is the scroll amount when the number of contacts is 601: 3. As can be seen from the graph, even when the initial speed is the same, as the attenuation coefficient 602 decreases, the scroll amount that moves from the initial speed until the speed is fully attenuated becomes a longer distance. That is, if the attenuation coefficient 602 is small, scrolling can be continued for a long time with slow scrolling. Therefore, it is possible to scroll over a wide range while checking the content 3.

  Therefore, in order to scroll the display area 4 over a wider range of the content 3, the user only has to increase the number of contacts 12 and input a scroll operation instruction, and there is no need to increase the scroll speed. Therefore, it is possible to scroll the display area 4 over a longer distance while maintaining the visibility of the content 3. Alternatively, in order to scroll the display area 4 over a longer distance, the user does not need to repeat the scroll operation instruction multiple times. Therefore, the usability of the information processing apparatus 1 is improved.

  In the operation flow of FIG. 7, in the process of step S <b> 701, the control unit 200 of the information processing apparatus 1 functions as the counting unit 211. In the process of step S <b> 702, the control unit 200 of the information processing apparatus 1 functions as the determination unit 212. In the process of step S703, the control unit 200 of the information processing apparatus 1 functions as the determination unit 213. In the process of step S704, the control unit 200 of the information processing device 1 functions as the first attenuation amount calculation unit 216. In the processing from step S705 to step S706, the control unit 200 of the information processing apparatus 1 functions as the second attenuation amount calculation unit 217. In the process of step S707, the control unit 200 of the information processing apparatus 1 functions as the changing unit 215.

  Subsequently, a process of changing the scroll amount of the display area 4 according to the number of the contacts 12 according to the third embodiment will be described with reference to FIGS. 9 to 10. In the third embodiment, the viscous friction coefficient used in the damping motion equation that defines how the scroll speed is attenuated is changed according to the number of contact points 12, so that the display area 4 stops moving after scrolling. The scroll amount representing the distance until the change is changed.

  FIG. 9 is a diagram illustrating the viscous friction coefficient change information 900 according to the third embodiment. In one embodiment, the viscous friction coefficient change information 900 is stored in the storage unit 220 of the information processing apparatus 1. The viscous friction coefficient change information 900 is information that associates the number of contact points 12 (the number of contact points 901) when a scroll operation instruction is input with the viscous friction coefficient 902. For example, when the number of the contacts 12 when the scroll operation instruction is input is two, the viscous friction coefficient 902: β2 associated with the number of contacts 901: 2 is acquired from the viscous friction coefficient change information 900. Is done. The viscous friction coefficient 902 is a coefficient that defines the slipperiness of an object. In the third embodiment, the viscous friction coefficient 902 is a coefficient that defines the slipperiness of the display area 4 when scrolling. The viscous coefficient of friction 902 is used in a damped motion equation that defines how the scroll speed is damped. When the viscous friction coefficient 902 is changed, the damping speed of the scroll speed is changed according to the equation of the damping motion.

  FIG. 10 is a diagram illustrating a process of changing the scroll amount of the display area 4 according to the number of contacts 12 executed by the control unit 200 of the information processing apparatus 1 according to the third embodiment. The operation flow of the process of changing the scroll amount of the display area 4 in FIG. 10 is implemented, for example, when the control unit 200 reads and executes the program 221 stored in the storage unit 220. In one embodiment, when an operation instruction is input on the touch panel 2 of the information processing apparatus 1, the process of changing the scroll amount of the display area 4 in FIG. 10 starts. In step S <b> 1001, the control unit 200 counts the number of contacts 12 of the detection target 10 that are in contact with the touch panel 2 when an operation instruction is input. In step S <b> 1002, the control unit 200 determines whether the input operation instruction is a scroll operation instruction based on the locus of the contact 12 on the touch panel 2. The determination of whether or not this is a scroll operation instruction may be performed, for example, as described with reference to step S402 and FIG.

  In step S1002, when the input operation instruction is not scrolling (No in step S1002), the operation flow ends. On the other hand, if the input operation instruction is scrolling (Yes in step S1002), the flow proceeds to step S1003. In step S <b> 1003, the control unit 200 determines the initial scroll speed for moving the display area 4 with respect to the content 3 in scrolling. In one embodiment, the initial scroll speed is determined according to the movement speed of the locus of the contact 12 in a predetermined period immediately before the contact 12 leaves the touch panel 2 when an operation instruction determined to be scroll is input. For example, the initial speed may be determined in proportion to the moving speed of the contact 12 in a predetermined period immediately before the detection target object 10 leaves the touch panel 2. The moving speed of the contact point 12 represents the moving speed of the detection target object 10 when the detection target object 10 is separated from the touch panel 2, for example.

Subsequently, in step S1004, the control unit 200 refers to the viscous friction coefficient change information 900 and acquires the viscous friction coefficient 902 associated with the number of contacts 901 corresponding to the number of contacts 12 counted in step S1001. In step S1005, the control unit 200 substitutes the acquired viscous friction coefficient 902 for the equation of motion of the damped motion. The equation of motion of the damping motion is an equation that defines the damping of the motion with respect to the content 3 of the display area 4 in scrolling. The equation of motion of the damping motion may be, for example, the following mathematical formula.

  In the above equation, β is a viscous friction coefficient, k is a spring multiplier, and x is a speed. Note that a predetermined value is used for the spring multiplier k according to the specifications of the information processing apparatus 1. The scroll speed for the content 3 in the display area 4 is x and changes with time. In addition, when the value of the viscous friction coefficient β that defines the slipperiness of an object becomes small, the display area 4 becomes slippery with respect to the content 3, and continues to slide for a longer time and moves a longer distance. On the contrary, when the value of the viscous friction coefficient β increases, the display area 4 becomes difficult to slide with respect to the content 3, so that the sliding time is shortened and the display area 4 moves a shorter distance. In the third embodiment, the value of the viscous friction coefficient 902 obtained from the viscous friction coefficient change information 900 according to the number of the contacts 12 is used as the viscous friction coefficient β.

  In step S1006, the control unit 200 executes scrolling so as to attenuate the scroll speed from the initial speed in accordance with the damping motion equation obtained in step S1005, thereby changing the scroll amount. In step S1006, when the scroll amount is changed by executing the scroll using the viscous friction coefficient corresponding to the number of the contacts 12 in the equation of the damping motion, the operation flow ends.

  As described above, in the operation flow of FIG. 10, the viscous friction coefficient 902 is acquired from the viscous friction coefficient change information 900 according to the number of the contacts 12. Then, the obtained viscous friction coefficient 902 is substituted into a damping motion equation. By reducing the scroll speed from the initial speed according to the equation of the damping motion obtained by the substitution, the scroll amount representing the distance from when the display area 4 starts to move until it stops is changed. In other words, the scroll for scrolling the display area 4 with respect to the content 3 by changing the value of the viscous friction coefficient β used in the equation of the damping movement defining the damping movement of the display area 4 according to the number of the contacts 12. The amount is changed. Therefore, the user can change the scroll amount by changing the number of contacts 12 to be brought into contact with the touch panel 2 when inputting a scroll operation instruction.

  In the operation flow of FIG. 10 described above, the control unit 200 of the information processing apparatus 1 functions as the counting unit 211 in the process of step S1001. Further, in the process of step S1002, the control unit 200 of the information processing apparatus 1 functions as the determination unit 212. In the process of step S1003, the control unit 200 of the information processing apparatus 1 functions as the determination unit 213. In the processing from step S1004 to step S1006, the control unit 200 of the information processing apparatus 1 functions as the changing unit 215.

  As illustrated in the above first to third embodiments, in some embodiments, the scroll amount is changed according to the number of contacts 12 when an operation instruction is input. Therefore, in order to change the scroll amount indicating the moving distance of the display area 4 in scrolling, the user only has to change the number of contacts 12 and input a scroll operation instruction, and it is not necessary to increase the scroll speed. Therefore, it is possible to scroll the display area 4 over a longer distance while maintaining the visibility of the content 3. Alternatively, in order to scroll the display area 4 over a longer distance, the user does not need to repeat the scroll operation instruction multiple times. Therefore, the usability of the information processing apparatus 1 is improved.

  In the above-described first embodiment, the example in which one or more different values are associated with each contact number 301 as the scroll amount coefficient 302 included in the scroll amount change information 300 has been described. However, the embodiment is not limited to this. For example, a value smaller than 1 may be associated with the scroll amount coefficient 302 associated with each contact number 301. Also in this case, if the value associated with each of the plurality of contact numbers 301 is different, the user can change the scroll amount according to the number of the contact points 12. Usability can be improved. Similarly, in the second embodiment, the example in which different values in the range of 0 to 1 are associated with the number of contacts 601 as the attenuation coefficient 602 has been described. However, the embodiment is not limited to this, and for example, a value larger than 1 may be associated as the value of the attenuation coefficient 602 associated with each contact number 601. Also in this case, for example, if the value of the attenuation coefficient 602 associated with each of the plurality of contact points 601 is different, the user can change the scroll amount according to the number of contact points 12, and accordingly The usability of the information processing apparatus 1 can be improved. The same applies to the viscous friction coefficient 902, and an arbitrary value can be set according to the mode to be implemented. If the value of the viscous friction coefficient 902 associated with each of the plurality of contact numbers 901 is different, the user can change the scroll amount according to the number of the contact points 12. Usability can be improved.

  Further, the order of the magnitude of the scroll amount coefficient 302 associated with the number of contacts 301 may be arbitrarily set. For example, the scroll amount coefficient 302: 1.5 is set for the contact number 301: 1, the scroll amount coefficient 302: 0.8 is set for the contact number 301: 2, the scroll amount coefficient 302: 3 is set for the contact number 301: 3, and so on. It may be set. Similarly, the order of the magnitude of the attenuation coefficient 602 associated with the number of contacts 601 and the order of the magnitude of the viscous friction coefficient 902 associated with the number of contacts 901 may be any order.

  In addition, with respect to the number of contacts included in the scroll amount change information 300, the attenuation amount change information 600, and the viscous friction coefficient change information 900, a setting for changing the scroll amount so that the display area 4 is moved to the end of the content 3 is supported. It may be attached. In this case, for example, when a scroll operation instruction is input with the number of contacts, the control unit 200 changes the scroll amount so as to move the display area 4 to the end of the content 3 and executes scrolling.

  In the above description, the direction of the locus 15 of one contact 12 and the angle α formed with respect to the direction of the locus 15 of the other contact 12 fall within a predetermined angle as the determination of the scroll operation instruction by the plurality of contacts 12. An example was described in which scrolling is determined when facing. However, the embodiment is not limited to this. For example, when one contact 12 of the plurality of contacts 12 is swiped, if another contact 12 does not move and touches the touch panel 2 as a fixed point, it is determined that a scroll operation instruction has been input. You may comprise as follows. In the above description, the input of an operation instruction via the touch panel 2 has been described as an example, but the embodiment is not limited to this. For example, in some embodiments, a wheel operation while clicking with a mouse may be applied as an alternative to inputting a scroll operation instruction by multi-touch.

  In the above-described embodiment, the scroll operation of the display area 4 with respect to the content 3 has been described as an example. However, the target to which the display area 4 is scrolled may be other than the content 3.

  In the second embodiment, as a predetermined function for attenuating the scroll speed, a function in which the attenuation amount changes with time is illustrated in FIG. However, the predetermined function used to attenuate the scroll speed is not limited to this. For example, a function that linearly attenuates the scroll speed may be used.
