Description

  The present invention relates to a scroll device, a scroll method, and a program for scrolling display contents on a screen in response to an input operation via a touch panel.

  In recent years, electronic devices equipped with a touch panel are increasing. A touch panel that can be operated intuitively by a user is widely used as a device that receives an input operation of an electronic device. The touch panel has the same reception of an input operation for a screen of a display unit (for example, an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence) display) provided in the electronic device and a display of a processing result of the electronic device for the input operation. Allows you to do it in the screen.

  When content having a large display size that cannot be displayed on the screen size of the electronic device on which the touch panel is mounted is displayed, the user browses the entire content by scrolling the touch panel. In order to simplify the scroll operation, for example, an electronic device disclosed in Patent Document 1 is known.

  When it is determined that the finger flicks the object, the electronic device disclosed in Patent Literature 1 performs the first inertia scroll in the direction of the flick operation. In addition, when it is determined that the flick operation is performed in the direction opposite to the slide operation after the finger performs the slide operation on the object, the electronic device executes the second inertia scroll in the flick operation direction. The second inertia scroll has a longer scroll distance or a higher scroll speed than the first inertia scroll. Thereby, the electronic device shown in Patent Document 1 can easily scroll an object to a predetermined position without repeating unnecessary operations.

  Note that inertia scrolling means that when the screen is scrolled quickly, the scrolling is maintained for a predetermined time so that inertia is applied without suddenly stopping even if the finger is released from the screen. It is a function.

JP 2012-14524 A

  However, in inertial scrolling, the scrolling speed gradually decreases according to the elapsed time from when the finger leaves the screen, and the scrolling eventually stops. For this reason, in Patent Document 1, when content that has a large display size (for example, a map) is desired to be scrolled quickly or continuously, the user is required to execute the second inertial scroll. There was a problem that it was necessary to repeat the operation.

  Hereinafter, embodiments of a scroll device, a scroll method, and a program according to the present invention will be described with reference to the drawings. The scroll device according to the present embodiment is an electronic device including a display unit that displays data on a screen, such as a mobile phone, a smartphone, a tablet terminal, a digital still camera, a PDA (personal digital assistant), or an electronic book terminal. Hereinafter, a mobile terminal (for example, a smartphone) will be described as an example of the scroll device of each embodiment.

  Note that the present invention can also be expressed as a scroll device as a device or a program for operating the scroll device as a computer. Furthermore, the present invention can also be expressed as a scroll method having each operation (step) executed by the scroll device. That is, the present invention can be expressed in any category of an apparatus, a method, and a program.

(Explanation of terms necessary for each embodiment)
In the following description, a user's finger (for example, an index finger) is used as an example of an object (instruction medium) that approaches or touches the touch panel. However, the present invention is not limited to a finger, and may be a conductive stylus. The object (instruction medium) that approaches or comes into contact with the touch panel is not limited as long as it can detect the proximity and contact with the touch panel according to the structure and detection method of the touch panel.

  Also, two axes representing the horizontal plane of the touch panel are defined as an x-axis and a y-axis, and a direction of a vertical axis with respect to the horizontal plane of the touch panel, that is, an axis representing the height direction of the object is defined as a z-axis.

  In the following description, “contact coordinates” indicate coordinates (x, y) for specifying the position on the horizontal plane of the touch panel when the touch panel detects the touch of the finger, and “proximity coordinates” refers to the touch panel. The coordinates (x, y, z) for specifying the position in the proximity detectable region in the space when the proximity of is detected. The z coordinate value of the proximity coordinates represents the height at which the finger is spaced apart from the horizontal plane of the touch panel.

  In the following description, an operation of holding a finger over a position in a predetermined proximity detectable region in space in a direction away from the surface of the touch panel is defined as a “hover operation”. In particular, it is an example of a hover operation, and an operation of sliding (moving) from a position in the space held by the hover operation to be substantially parallel to the surface of the touch panel is defined as a “hover slide operation”. An operation of keeping a finger over a position in the proximity detectable region without moving the is defined as a “hover hold operation”.

  Further, an operation in which a finger directly contacts the surface of the touch panel is not a “hover operation” but a “touch operation”. An example of a touch operation, and an operation of sliding (moving) in a state where a finger is in contact with the surface of the touch panel is defined as a “touch slide operation”.

  Furthermore, as an example of a touch operation, an operation in which a finger touches a horizontal surface of the touch panel to quickly pay or play is defined as “flick operation” or “touch flick operation”. On the other hand, an example of a hover operation, such as a flick operation, an operation for quickly paying or flipping a finger within a predetermined proximity detectable area on a space separated from the surface of the touch panel is defined as a “hover flick operation”. To do. Hereinafter, “touch flick operation” and “hover flick operation” will be described separately.

  The predetermined proximity detectable region for detecting the hover operation, that is, the distance between the finger and the surface of the touch panel is inversely proportional to the capacitance detected by the touch panel. A value corresponding to the range is preferable.

  Further, when the finger enters the proximity detectable area of the touch panel, the touch panel detects that the finger has approached. In this way, the operation for starting the detection of the proximity state of the finger is defined as “hover-in” so that the finger is held from the height outside the proximity detectable region of the touch panel to the height within the proximity detectable region, and the touch panel is defined. An operation for preventing the proximity state of the finger from being detected so as to move the finger away from the proximity detectable region and away from the proximity detectable region is defined as “hover out”.

  Also, with the peak speed of the initial operation for starting scrolling (for example, touch flick operation), that is, the initial scroll speed, the scroll speed gradually decreases with the elapsed time from the initial operation. Scrolling to zero is defined as “inertial scrolling”.

(First embodiment)
In the first embodiment, the mobile terminal 100 starts inertial scrolling according to a finger contact operation (for example, a touch flick operation) and then detects a finger hover operation (for example, a hover hold operation). Scrolling while maintaining the scroll speed and scroll direction when a finger hover operation is detected by interrupting inertial scrolling and changing the amount of change in scrolling time of inertial scrolling (see below) to zero Run.

(Functional configuration of the mobile terminal 100 of the first embodiment)
First, a functional configuration of the mobile terminal 100 according to the first embodiment will be described with reference to FIG. FIG. 1 is a block diagram illustrating a functional configuration of the mobile terminal 100 according to the first embodiment. 1 includes a proximity detection unit 5, a contact detection unit 10, a proximity coordinate evaluation unit 15, a contact coordinate evaluation unit 20, a proximity state management unit 25, a contact operation determination unit 30, an application 50, and display screen data generation. Part 60 and display part 70. The application 50 as a scroll control unit includes a state change control unit 53 and a change amount adjustment unit 56.

  The proximity detection unit 5 detects whether or not the finger FG of the user of the mobile terminal 100 is close to the touch panel TP at a predetermined cycle. For example, when the finger FG performs a hover operation (including a hover slide operation, a hover hold operation, and a hover flick operation), the proximity detection unit 5 detects that the finger FG has approached the touch panel TP. The proximity detection unit 5 outputs a proximity detection signal indicating that the finger FG has approached the touch panel TP to the proximity coordinate evaluation unit 15.

  The contact detection unit 10 detects whether or not the finger FG of the user of the mobile terminal 100 has touched the touch panel TP at a predetermined cycle. For example, when the finger FG performs a touch operation (including a touch slide operation and a touch flick operation), the contact detection unit 10 detects that the finger FG has touched the touch panel TP. The contact detection unit 10 outputs a contact detection signal indicating that the finger FG has touched the touch panel TP to the contact coordinate evaluation unit 20.

  The proximity detection unit 5 and the contact detection unit 10 can be configured using the touch panel TP. In FIG. 1, the proximity detection unit 5 and the contact detection unit 10 are configured separately. You may comprise.

  The proximity coordinate evaluation unit 15 calculates proximity coordinates (x, y, z) of the finger FG with respect to the touch panel TP based on the proximity detection signal output by the proximity detection unit 5 and outputs the proximity coordinates to the proximity state management unit 25. Among the proximity coordinates (x, y, z), the x component and the y component are coordinate values representing the position on the surface of the touch panel TP, and the z component is a distance in the z-axis direction between the finger FG and the touch panel TP. That is, the coordinate value represents the height of the finger FG with respect to the touch panel TP.

  The contact coordinate evaluation unit 20 calculates contact coordinates (x, y) at which the finger FG contacts the touch panel TP based on the contact detection signal output by the contact detection unit 10 and outputs the contact coordinates (x, y) to the contact operation determination unit 30.

  The proximity state management unit 25 manages a proximity state indicating whether or not the finger FG is close to the touch panel TP based on the proximity coordinates (x, y, z) output from the proximity coordinate evaluation unit 15. Yes. For example, the proximity state management unit 25 detects that the finger FG has hovered in because the finger FG has moved from a position outside the proximity detectable area of the touch panel TP to a position within the proximity detectable area. Further, the proximity state management unit 25 detects that the finger FG has hovered out by moving the finger FG from a position within the proximity detectable region of the touch panel TP to a position outside the proximity detectable region. The proximity state management unit 25 notifies the application 50 of a proximity state indicating whether or not the finger FG is close to the touch panel TP.

  The contact operation determination unit 30 determines the type of touch operation performed by the finger FG on the touch panel TP based on the contact coordinates (x, y) output from the contact coordinate evaluation unit 20. Here, the types of touch operations determined by the contact operation determination unit 30 are, for example, touch operations, touch slide operations, and touch flick operations, but are not limited to these operations. The contact operation determination unit 30 notifies the application 50 that the determined touch operation type, that is, any touch operation has been performed.

  Further, the contact operation determination unit 30 is configured such that, for example, when the finger FG performs a touch flick operation, the finger FG is a surface of the touch panel TP in the touch flick operation based on the contact coordinates (x, y) output by the contact coordinate evaluation unit 20. The movement speed of the finger FG when paying or playing the top is calculated and notified to the application 50.

  The contact operation determination unit 30 uses both the proximity coordinates (x, y, z) calculated by the proximity coordinate evaluation unit 15 and the contact coordinates (x, y) calculated by the contact coordinate evaluation unit 20. The moving speed of the finger FG in the flick operation may be calculated. Thereby, the contact operation determination part 30 can calculate the moving speed of the finger FG when the finger FG pays or flips the surface of the touch panel TP in the touch flick operation with high accuracy.

  The application 50 is an application program that is installed in the mobile terminal 100 in advance. The contents of the application 50 in each embodiment are not particularly limited. For example, the application 50 is a map application that causes the corresponding map content to be displayed on the display unit 70 in accordance with a user input operation.

  When the touch operation type determined by the contact operation determination unit 30 is a touch flick operation, the state change control unit 53 performs inertial scrolling according to the moving speed when the finger FG pays or flips the surface of the touch panel TP. Scroll initial speed is calculated. The state change control unit 53 uses the initial scroll speed and the initial value of the temporal change amount of the scroll speed in inertial scroll (for example, acceleration, the same applies hereinafter) to determine the scroll speed characteristics that change over time, and sets the determined scroll speed to the determined scroll speed. Perform inertial scrolling accordingly.

  Note that acceleration (<0), which is an example of the temporal change amount of the scroll speed, is known in the state change control unit 53 and corresponds to a friction coefficient for reducing the scroll speed of the inertial scroll according to the elapsed time. Further, the temporal change amount of the scroll speed may be a fixed initial value regardless of the elapsed time from the time when the touch flick operation is performed, or may be decreased from the initial value together with the elapsed time.

  The state change control unit 53 starts inertial scrolling of the map content displayed on the screen of the display unit 70 according to the calculated scroll initial speed and the temporal change amount of the scroll speed (see FIG. 2B). . Therefore, if inertial scrolling continues, the scroll speed gradually decreases according to the elapsed time from the time when the touch flick operation is performed, with the initial scroll speed at the time when the touch flick operation is performed as a peak. The inertial scroll stops (see the scroll curve C0 shown in FIG. 3).

  When the proximity state management unit 25 detects that the finger FG is hovered in, the change amount adjustment unit 56 instructs the state change control unit 53 to set the amount of time change in the scroll speed to zero. In response to an instruction from the change amount adjustment unit 56, the state change control unit 53 changes the temporal change amount of the scroll speed to zero. As a result, the state change control unit 53 interrupts the inertial scroll, and executes the scroll while maintaining the scrolling speed and the scrolling direction of the inertial scroll when the hover-in of the finger FG is detected.

  Further, when the proximity state management unit 25 detects that the finger FG has hovered out, the change amount adjustment unit 56 instructs the state change control unit 53 to change the amount of change in scroll speed over time to the original value. To do. Here, the original value is a value of a temporal change amount of the scroll speed of the inertial scroll when the proximity state management unit 25 detects the hovering of the finger FG. In response to an instruction from the change amount adjustment unit 56, the state change control unit 53 changes the temporal change amount of the scroll speed to the original value. Thereby, the state change control part 53 can restart the inertial scroll according to the scroll speed when the hover-in of the finger FG is detected.

  The display screen data generation unit 60 as a display control unit generates display screen data before or after the application 50 is scrolled and displays the display screen data on the screen of the display unit 70. In FIG. 1, the display screen data generation unit 60 is configured differently from the application 50, but may be included in the application 50.

  The display unit 70 has a function of displaying data on the screen, and displays the display screen data output from the display screen data generation unit 60 on the screen. The display screen data is data displayed on the screen of the display unit 70 in the application 50.

(Outline of operation of first embodiment)
Next, an outline of the operation of the mobile terminal 100 of the present embodiment will be described with reference to FIG. 2A to 2D are schematic diagrams illustrating an operation outline of the mobile terminal 100 according to the first embodiment.

  FIG. 2A shows a state in which the map content of the application 50 is displayed on the screen of the display unit 70. The touch panel TP is mounted corresponding to the screen of the display unit 70. For example, when the finger FG performs a touch flick operation toward the upper right direction of the touch panel TP, the mobile terminal 100 starts inertial scrolling of the map content in the direction in which the finger FG has moved in the touch flick operation (see FIG. 2B). . FIG. 2B shows a state when the mobile terminal 100 starts inertial scrolling in the same direction as the touch flick operation of the finger FG.

  When the mobile terminal 100 detects that the finger FG has hovered in after the touch flick operation on the touch panel TP and detects that the finger FG is hovered in, the mobile terminal 100 changes the amount of change in the scroll speed over time in the inertia scroll to zero. Interrupt. Furthermore, the mobile terminal 100 executes scrolling while maintaining a constant scroll speed and scroll direction when the hover-in of the finger FG is detected (see FIG. 2C). FIG. 2C shows a state in which the mobile terminal 100 is scrolling in a state where the scroll speed and the scroll direction are kept constant by the finger FG performing a hover operation on the touch panel TP. Thereby, while the finger FG continues the hover hold operation, the mobile terminal 100 can maintain the scroll speed and the scroll direction when the hover-in of the finger FG is detected, and does not require repeated operations for scrolling. , You can quickly scroll the map content.

  When the mobile terminal 100 detects the hover-out of the finger FG by moving the finger FG that has been hover-holding from the position of the proximity detectable region of the touch panel TP, And the inertial scroll is restarted (see FIG. 2D). FIG. 2D shows a state when the hover-out is detected due to the finger FG moving away from the position of the proximity detectable region of the touch panel TP.

(Operation of the mobile terminal 100 of the first embodiment)
Next, the operation of the mobile terminal 100 of this embodiment will be described with reference to FIGS. 3 and 4. FIG. 3 is a graph showing a change in scroll speed with time in the first embodiment. FIG. 4 is a flowchart for explaining the operation of the mobile terminal 100 according to the first embodiment. In FIG. 3, time t0 is the time when the touch flick operation is performed, time t1 and time t3 are times when the hover-out state is detected, and time t2 is the time when the state where the finger FG is hovered in is detected.

  In FIG. 3, three scroll curves C0, C1, and C2 are shown. The scroll curve C0 is a scroll curve corresponding to the conventional inertial scroll. That is, the scroll initial speed v0 at the time t0 is a peak, the scroll speed v gradually decreases with the elapsed time from the time t0, finally becomes zero, and inertial scrolling stops.

  The scroll curve C1 is a scroll curve when a touch flick operation and hover-in are detected at the time t0 at the same time. In the scroll curve C1, since the touch flick operation and the hover-in are simultaneously detected at time t0, the inertial scroll is interrupted from time t0 to time t1, and constant speed scrolling is executed. For this reason, the same scroll speed v as the scroll initial speed v0 is maintained. In addition, since the hover-out is detected at time t1, the constant speed scrolling is ended and the inertial scrolling is resumed after time t1, so that the scroll speed v is gradually reduced to the final value similarly to the scroll curve C0. The inertial scroll stops.

  The scroll curve C2 is a scroll curve when a touch flick operation is detected at time t0 and hover-in is detected at time t2. In the scroll curve C2, since hover-in is detected at time t2, the same scroll speed v as the scroll speed v1 of inertial scroll at time t2 is maintained from time t2 to time t3. Since the hover-out is detected at time t3, the constant speed scrolling is ended and the inertial scrolling is resumed after time t3, so that the scroll speed v is gradually reduced and finally the same as the scroll curve C0. The inertial scroll stops.

  In FIG. 4, the contact operation determination unit 30 determines the type of touch operation performed by the finger FG on the touch panel TP based on the contact coordinates (x, y) output from the contact coordinate evaluation unit 20 (S11). When the touch operation determination unit 30 determines that the type of touch operation is a touch flick operation (S11, YES), the application 50 indicates that the determined touch operation type, that is, any touch operation has been performed. Notify

  Further, the contact operation determination unit 30 is configured such that, for example, when the finger FG performs a touch flick operation, the finger FG is a surface of the touch panel TP in the touch flick operation based on the contact coordinates (x, y) output by the contact coordinate evaluation unit 20. The movement speed of the finger FG when paying or playing the top is calculated and notified to the application 50.

  The state change control unit 53 calculates the scroll initial speed of the inertial scroll according to the moving speed of the finger FG output from the contact operation determination unit 30. The state change control unit 53 determines the scroll speed characteristic that changes with time using the initial scroll speed and the initial value of the temporal change amount of the scroll speed in the inertial scroll, and executes the inertial scroll according to the determined scroll speed. (S12).

  The proximity state management unit 25 detects whether or not the finger FG is close to the touch panel TP based on the proximity coordinates (x, y, z) output from the proximity coordinate evaluation unit 15 (S13). When the proximity state management unit 25 detects that the finger FG has hovered in (S13, YES), the proximity state management unit 25 notifies the application 50 that the finger FG has hovered in.

  In response to the notification from the proximity state management unit 25, the change amount adjustment unit 56 instructs the state change control unit 53 to set the temporal change amount of the scroll speed to zero. In response to an instruction from the change amount adjustment unit 56, the state change control unit 53 changes the amount of time change in the scroll speed to zero (S14). Thereby, the state change control unit 53 interrupts the inertial scroll and executes the scroll while maintaining the scroll speed and the scroll direction of the inertial scroll when the hover-in of the finger FG is detected (S12).

  On the other hand, when the proximity state management unit 25 detects that the finger FG has hovered out (S13, NO), the proximity state management unit 25 notifies the application 50 that the finger FG has hovered out. In response to the notification from the proximity state management unit 25, the change amount adjustment unit 56 instructs the state change control unit 53 to change the temporal change amount of the scroll speed to the original value. In response to an instruction from the change amount adjustment unit 56, the state change control unit 53 changes the temporal change amount of the scroll speed to the original value. Thereby, the state change control part 53 restarts the inertial scroll according to the scroll speed when the hover-in of the finger FG is detected (S15). Therefore, the scroll speed gradually decreases with the elapsed time from the scroll speed when the hover-in of the finger FG is detected.

  The state change control unit 53 determines whether or not the scroll speed is greater than zero (S16). If the state change control unit 53 determines that the scroll speed is greater than zero (S16, YES), it continues scrolling according to the current scroll speed (S12). On the other hand, when the state change control unit 53 determines that the scroll speed is equal to or lower than zero, that is, zero (S16, NO), the scrolling in the portable terminal 100 ends.

  As described above, when the mobile terminal 100 according to the present embodiment detects that the finger FG has hovered in after starting the inertial scroll according to the touch flick operation of the finger FG, the inertial scroll is interrupted and the proximity state management unit 25 Scrolling is executed while maintaining the scrolling speed and scrolling direction of the inertial scroll when the hover-in of the finger FG is detected.

  Accordingly, the mobile terminal 100 according to the present embodiment can maintain the scroll speed and the scroll direction when the hovering of the finger FG is detected while the finger FG continues the hover hold operation, for example, and can scroll the map content. Can be executed quickly. That is, the mobile terminal 100 can easily execute scrolling of content having a large display size without requiring repeated operations for performing inertial scrolling a plurality of times.

  Although not shown in FIGS. 3 and 4, when the mobile terminal 100 of this embodiment detects hover-in again after detecting hover-out of the finger FG, the hover-in of the finger FG is detected again. Scrolling may be executed while maintaining the scrolling speed and scrolling direction of the inertial scroll.

  In addition, when the mobile terminal 100 of the present embodiment further detects a hover flick operation while the finger FG is performing a hover hold operation, the mobile terminal 100 hovers in the finger FG according to the moving speed of the finger FG in the hover flick operation. It is also possible to execute the constant speed scrolling after further increasing the constant speed scrolling speed at the time of detection. Thereby, even when the scroll speed when the hover-in is detected is not preferable for the user, the mobile terminal 100 can execute the scroll according to the appropriate scroll speed according to the user's hover flick operation.

(Second Embodiment)
In the second embodiment, the mobile terminal 200 starts inertial scrolling in response to a finger contact operation (for example, touch flick operation) and then interrupts inertial scrolling while a finger hover operation is detected. The scroll speed is gradually reduced until the scroll speed reaches a predetermined convergence speed (see later), and after the scroll speed reaches the convergence speed, scrolling is executed with the scroll speed kept constant.

(Functional configuration of the mobile terminal 200 of the second embodiment)
A functional configuration of the mobile terminal 200 according to the second embodiment will be described with reference to FIG. FIG. 5 is a block diagram illustrating a functional configuration of the mobile terminal 200 according to the second embodiment. The mobile terminal 200 shown in FIG. 5 includes a proximity detection unit 5, a contact detection unit 10, a proximity coordinate evaluation unit 15, a contact coordinate evaluation unit 20, a proximity state management unit 25, a contact operation determination unit 30, an application 50A, and display screen data generation. Part 60 and display part 70. The application 50A as the scroll control unit includes a state change control unit 53A, a change amount adjustment unit 56A, and a temporary speed holding unit 59. In the description of each part of the mobile terminal 200 shown in FIG. 5, the same or similar reference numerals are used for the same components as those of the mobile terminal 100 shown in FIG.

  The state change control unit 53A calculates the convergence speed based on the scroll initial speed of the inertial scroll and stores it in the temporary speed holding unit 59. Here, the convergence speed is a lower limit value of the scroll speed in scrolling after the hover-in of the finger FG is detected, and the same applies to the following embodiments. The convergence speed may be a value determined according to the scroll initial speed in inertial scroll, or may be a fixed value regardless of the scroll initial speed in inertial scroll. In each of the following embodiments, the convergence speed will be described as being a value calculated by the state change control unit 53A according to the scroll initial speed in inertial scroll (for example, a value that is ½ of the scroll initial speed).

  When the change amount adjustment unit 56A detects that the finger FG is hovered in, the change amount adjustment unit 56A changes the state change amount of the scroll speed so as to converge to the convergence speed stored in the temporary speed holding unit 59. The control unit 53A is instructed. The state change control unit 53A changes the amount of change in scroll speed over time in response to an instruction from the change amount adjustment unit 56A. Thereby, the state change control unit 53A interrupts the inertial scroll and executes the scroll so that the scroll speed converges to the convergence speed. Therefore, in the present embodiment, the mobile terminal 200 can perform scrolling while maintaining a scroll speed that does not become less than the convergence speed while it is detected that the finger FG has hovered in.

(Operation of the mobile terminal 200 of the second embodiment)
Next, the operation of the mobile terminal 200 of this embodiment will be described with reference to FIGS. FIG. 6 is a graph showing a change in scroll speed with time in the second embodiment. FIG. 7 is a flowchart for explaining the operation of the mobile terminal 200 according to the second embodiment. In FIG. 6, time t0 is the time when the hover-in is detected simultaneously with the touch flick operation, time t4 is the time when the scroll speed v becomes the convergence speed v2, and time t5 is the time when the hover-out is detected. The scroll curve C0 is the same as the scroll curve C0 shown in FIG. In the description of the flowchart illustrated in FIG. 7, the same operations as those in the flowchart illustrated in FIG. 4 are denoted by the same reference numerals, and description thereof is omitted or simplified, and different contents will be described.

  In the scroll curve C4, since the touch flick operation and the hover-in are detected at the time t0 at the same time, the inertial scroll is interrupted, and the scroll speed v gradually decreases from the time t0 to the time t5. The scroll speed v is maintained at the convergence speed v2 from time t4 to time t5 when the scroll speed v becomes the convergence speed v2. Further, since the hover-out is detected at time t5 and the inertial scroll is resumed, the scroll speed v is gradually reduced from the convergence speed v2 and finally becomes zero, and the inertial scroll is stopped.

  In FIG. 7, when the proximity state management unit 25 detects that the finger FG is hovered (S13, YES), the proximity state management unit 25 notifies the application 50 that the finger FG is hovered. The change amount adjustment unit 56A instructs the state change control unit 53A to change the time change amount of the scroll speed v so that the scroll speed v converges to the convergence speed v2 stored in the temporary speed holding unit 59. The state change control unit 53A changes the amount of change in scroll speed over time in response to an instruction from the change amount adjustment unit 56A. Thereby, the state change control unit 53A interrupts the inertial scroll and executes the scroll so that the scroll speed converges to the convergence speed.

  The state change control unit 53A determines whether or not the current scroll speed v is greater than the convergence speed v2 stored in the temporary speed holding unit 59 (S21). If the state change control unit 53A determines that the current scroll speed v is greater than the convergence speed v2 stored in the temporary speed holding unit 59 (S21, YES), the state change control unit 53A converges the scroll speed v to the convergence speed v2. (S22).

  The contact operation determination unit 30 determines whether or not the finger FG that has been performing a hover operation (for example, a hover hold operation) has been touched (S23). When it is determined that the finger FG that has been operated by the hover has been touched (S23, YES), the contact operation determination unit 30 notifies the application 50 that the finger FG that has been operated by the hover has been touched. In response to the notification from the contact operation determination unit 30, the state change control unit 53A sets the scroll speed v to zero immediately or smoothly and stops scrolling (S24). If the finger FG that has been operated by the hover is not being touched (S23, NO), the scrolling is continued without being stopped, and the operation of the mobile terminal 200 returns to step S12.

  On the other hand, when the state change control unit 53A determines that the scroll speed v is equal to the convergence speed v2 (S21, NO), as long as the hover operation (for example, hover hold operation) of the finger FG is detected, the scroll speed v Scrolling is executed with v maintained at the convergence speed v2 (S12).

  If it is determined that the scroll speed in inertial scrolling is greater than zero after detecting that the finger FG has hovered out (YES in S16), the state change control unit 53A responds to the current scrolling speed. The scrolling is continued (S14A).

  As described above, the mobile terminal 200 according to the present embodiment starts inertial scrolling according to the touch flick operation of the finger FG, and then interrupts the inertial scroll and detects the scroll speed v while the finger hover operation is detected. The scroll speed v is gradually reduced until the convergence speed v2 is reached, and after the scroll speed v reaches the convergence speed v2, the scroll speed is executed with the scroll speed v maintained constant.

  Thereby, the mobile terminal 200 according to the present embodiment can detect the hover operation of the finger FG even when the scroll speed of the inertial scroll when the state where the finger FG is hovered is detected does not match the user's intention. Then, the scroll speed v can be gradually reduced to the convergence speed v2, and the scroll can be executed while maintaining the convergence speed v2. Therefore, for example, when the user wants to read and read the content, the scroll can be executed at an appropriate scroll speed.

(Third embodiment)
In the third embodiment, in addition to the operation of the second embodiment, the mobile terminal 300 starts automatic scrolling (see below) when a finger hover operation is detected for a certain period of time. During the automatic scrolling, the mobile terminal 300 gradually reduces the scroll speed until the convergence speed is reached, as in the second embodiment, and maintains the scroll speed constant after the scroll speed reaches the convergence speed. Execute auto scroll with.

(Functional structure of the portable terminal 300 of 3rd Embodiment)
A functional configuration of the mobile terminal 300 according to the third embodiment will be described with reference to FIG. FIG. 8 is a block diagram illustrating a functional configuration of the mobile terminal 300 according to the third embodiment. 8 includes a proximity detection unit 5, a contact detection unit 10, a proximity coordinate evaluation unit 15, a contact coordinate evaluation unit 20, a proximity state management unit 25, a contact operation determination unit 30, an application 50B, and display screen data generation. Unit 60B, display unit 70, and timer control unit 80. The application 50B as the scroll control unit includes a state change control unit 53B, a change amount adjustment unit 56B, and a temporary speed holding unit 59. In the description of each part of the mobile terminal 300 shown in FIG. 8, the same or similar reference numerals are used for the same components as those of the mobile terminal 200 shown in FIG.

  The timer control unit 80 has a time counting function in the portable terminal 300, and outputs the time information measured to the application 50B.

  When the proximity state management unit 25 detects that the finger FG is hovered in, the state change control unit 53B performs a certain time after the finger FG performs a touch flick operation based on the time information output from the timer control unit 80. It is determined whether the hover operation has been performed. The predetermined time may be a value defined in advance in the operation of the state change control unit 53B, or may be changed as appropriate.

  If the state change control unit 53B determines that the finger FG has hovered for a certain time or longer, the state change control unit 53B interrupts inertial scrolling and starts automatic scrolling. Here, the automatic scroll automatically reduces the scroll speed v to the convergence speed v2 automatically regardless of whether the finger FG is in the proximity state, and after the scroll speed v becomes the convergence speed v2, the convergence speed v2 is reached. This is an operation of executing scrolling while maintaining the above. The state change control unit 53B ends the automatic scrolling when the contact operation determination unit 30 detects that the finger FG has performed a touch operation.

  The display screen data generation unit 60B as the display control unit displays an index (for example, a mark) indicating the state in which the automatic scrolling is being executed while the state change control unit 53B is executing the automatic scrolling. When the automatic scrolling is finished, an index indicating the state in which the automatic scrolling is executed is hidden from the screen of the display unit 70. Thereby, display screen data generation part 60B can make a user recognize the state which is performing automatic scrolling.

(Operation of the mobile terminal 300 of the third embodiment)
Next, operation | movement of the portable terminal 300 of this embodiment is demonstrated with reference to FIGS. FIG. 9 is a graph showing a change in scroll speed with time in the third embodiment. FIG. 10 is a flowchart for explaining the operation of the mobile terminal 300 according to the third embodiment. FIG. 11 is a flowchart for explaining the details of the operation A of the mobile terminal 300 according to the third embodiment. In FIG. 9, time t0 is the time at which touch flick operation and hover-in are detected at the same time, time t4 is the time at which scrolling speed v becomes convergence speed v2, time t5 is the time at which hover-out is detected, and time t6 is touch This is the time when a certain time has elapsed from the time t0 when the flick operation was performed. The scroll curve C0 is the same as the scroll curve C0 shown in FIG. In the description of the flowchart shown in FIG. 10, the same operations as those in the description of the flowchart shown in FIG. 7 will be omitted or simplified using the same reference numerals, and different contents will be described.

  In the scroll curve C5, since the touch flick operation and the hover-in are simultaneously detected at the time t0, the inertial scroll is interrupted, and the scroll speed v converges from the scroll initial speed v0 after the time t0 as in the second embodiment. The speed gradually decreases so as to converge to the speed v2, and the scroll speed v becomes the convergence speed v2 at time t4. In addition, since automatic scrolling is started at time t6 when a predetermined time has elapsed from time t0, even if it is detected that the finger FG has hovered out at time t5, inertial scrolling is resumed as in the second embodiment. The scroll speed v is maintained at the convergence speed v2.

  The scroll curve C5 shows an example in which the touch flick operation and the hover-in are detected at the time t0 at the same time. However, when the hover-in is detected at a time after the time t0, the automatic scrolling is started. The starting time of a certain time is the time when hover-in is detected.

  In FIG. 10, the operation of the mobile terminal 300 of the present embodiment is the addition of an operation A between Step S13 and Step S21 of the operation of the mobile terminal 200 of the second embodiment. Since the operation of the mobile terminal 300 according to the present embodiment shown in FIG. 10 is the same as the operation of the mobile terminal 200 according to the second embodiment shown in FIG.

  In FIG. 11, when the proximity state management unit 25 detects that the finger FG is hovered (S13, YES), the proximity state management unit 25 notifies the application 50 that the finger FG is hovered. Based on the time information output from the timer control unit 80, the state change control unit 53B determines whether or not the finger FG has performed a hover operation for a certain period of time after the touch flick operation (S31). If it is determined that the hover operation has not been performed for a certain period of time after the finger FG performs a touch flick operation (S31, NO), the operation of the mobile terminal 300 proceeds to step S21.

  If the state change control unit 53B determines that the hover operation has been performed for a predetermined time or more after the finger FG performs the touch flick operation (S31, YES), the inertial scroll is interrupted and the automatic scroll is started. Further, the state change control unit 53B determines whether or not the current scroll speed v during automatic scrolling is greater than the convergence speed v2 stored in the temporary speed holding unit 59 (S32). If the state change control unit 53B determines that the current scroll speed v during automatic scrolling is greater than the convergence speed v2 stored in the temporary speed holding unit 59 (S32, YES), the scroll speed v is set to the convergence speed v2. (S33), and automatic scrolling according to the current scroll speed v is executed (S34). On the other hand, when the state change control unit 53B determines that the current scroll speed v during automatic scrolling is not greater than the convergence speed v2 stored in the temporary speed holding unit 59, that is, the convergence speed v2 (S32, NO), automatic scrolling according to the current scrolling speed v is executed without reducing the scrolling speed v (S34).

  The contact operation determination unit 30 determines whether or not the finger FG that has been performing a hover operation (for example, a hover hold operation) has been touched (S35). When it is determined that the finger FG that has been operated by the hover has been touched (S35, YES), the contact operation determination unit 30 notifies the application 50 that the finger FG that has been operated by the hover has been touched. In response to the notification from the contact operation determination unit 30, the state change control unit 53B immediately or smoothly sets the scroll speed v during automatic scrolling to zero and stops automatic scrolling (S36). When the finger FG that has been operated by the hover is not being touched (S35, NO), the automatic scrolling is continued without being stopped, and the operation of the portable terminal 300 returns to step S32.

  As described above, when the hover operation of the finger FG is detected for a certain time or longer after the touch flick operation, the mobile terminal 300 according to the present embodiment interrupts the inertia scroll and starts the automatic scroll. During the automatic scrolling, the mobile terminal 300 gradually reduces the scroll speed v during the automatic scroll until the convergence speed v2 is reached, and the scroll speed v becomes the convergence speed v2. Thereafter, automatic scrolling is executed in a state where the scroll speed v is maintained constant regardless of whether or not hover-in and hover-out are present.

  As a result, the mobile terminal 300 according to the present embodiment performs the hover operation for a certain time after the finger FG performs the touch flick operation, thereby interrupting the inertial scroll and easily starting the automatic scroll. Even if the finger FG is hovered out, the scroll speed v is maintained at the scroll speed when the automatic scrolling is started, so that the scroll speed v is gradually converged to the convergence speed v2 without imposing a burden on the finger FG. Automatic scrolling can be executed with reduced speed.

(Fourth embodiment)
In the fourth embodiment, in addition to the operation of the third embodiment, the mobile terminal 300 pauses automatic scrolling when a hover operation of a finger (for example, a hover hold operation) is detected during automatic scrolling. Alternatively, the speed is reduced to a predetermined constant speed slower than the current scroll speed, and when it is detected that the finger has hovered out, the automatic scrolling is resumed.

Since the functional configuration of the mobile terminal 300 of the fourth embodiment is the same as the configuration of the mobile terminal 300 shown in FIG. 8, the description of the same content is omitted or simplified, and the different content will be described.

  The state change control unit 53B determines whether or not the proximity state management unit 25 detects a hovered-in state from a state where the finger FG is hovering out during automatic scrolling. When the state change control unit 53B detects a state where the finger FG is hovered out from the state where the finger FG is hovering out during the automatic scrolling, the state change control unit 53B scrolls the automatic scroll when the hover-in is detected. The speed is stored in the temporary speed holding unit 59.

  The change amount adjustment unit 56B controls the state change so that the automatic scrolling is temporarily stopped when the proximity state management unit 25 detects that the finger FG is hovering out from the state of hovering out during the automatic scrolling. Instruct the unit 53B. The state change control unit 53B temporarily stops automatic scrolling in response to an instruction from the change amount adjustment unit 56B. Note that the state change control unit 53B may decelerate the scroll speed of the automatic scroll to a constant speed slower than the current scroll speed instead of temporarily stopping the automatic scroll. Also in the following description, it is assumed that the automatic scroll pause includes deceleration to a constant speed slower than the current scroll speed.

  In addition, the state change control unit 53B determines whether or not the proximity state management unit 25 has detected a state where the finger FG has hovered out from a state where the finger FG has hovered during the automatic scrolling pause. If the state change control unit 53B detects a state where the finger FG is hovering in from the state where the finger FG is hovering during the automatic scrolling pause, the current state scroll speed (= 0) is detected. Is changed to the scrolling speed stored in the temporary speed holding unit 59.

  The change amount adjustment unit 56B is configured to resume automatic scrolling when the proximity state management unit 25 detects that the finger FG has hovered in from the state in which the finger FG was hovered during the automatic scrolling pause. The change control unit 53B is instructed. The state change control unit 53B resumes automatic scrolling according to the scroll speed stored in the temporary speed holding unit 59 in response to an instruction from the change amount adjustment unit 56B.

In the description of each flowchart shown in FIGS. 13 and 14, the same operations as those in the flowcharts shown in FIGS. 10 and 11 are denoted by the same reference numerals, and the description will be omitted or simplified, and different contents will be described. .

  In the scroll curve C6, since the touch flick operation and the hover-in are simultaneously detected at time t0, the inertial scroll is interrupted, and after time t0, the scroll speed v changes from the scroll initial speed v0 to the convergence speed as in the second embodiment. The scroll speed v is gradually reduced to converge to v2, and the scroll speed v becomes the convergence speed v2 at time t4. In addition, since automatic scrolling is started at time t6 when a predetermined time has elapsed from time t0, even if it is detected that the finger FG has hovered out at time t5, inertial scrolling is resumed as in the second embodiment. The scroll speed v is maintained at the convergence speed v2.

  Further, in the scroll curve C6, when the state where the finger FG is hovered out from the state where the finger FG is hovering out at the time t7 is detected during the automatic scrolling after the time t6, the automatic scrolling is temporarily stopped and the scroll speed is 0. Become. When the state where the finger FG is hovering in at time t8 is detected, the automatic scrolling is resumed. The scroll speed of the automatic scroll immediately after the restart is the scroll speed of the automatic scroll immediately before time t7.

  The scroll curve C6 shows an example in which the touch flick operation and the hover-in are detected at the time t0 at the same time. However, when the hover-in is detected at a time after the time t0, the automatic scrolling is started. The starting time of the certain time is the time when the state where the finger FG is hovered in is detected.

If the state change control unit 53B determines that the proximity state management unit 25 has detected a state where the finger FG is hovering out from the state where the finger FG is hovering out during automatic scrolling (S41, YES), hover-in is detected. The scroll speed of the automatic scroll at that time is stored in the temporary speed holding unit 59 (S42).

  The change amount adjustment unit 56B instructs the state change control unit 53B to temporarily stop automatic scrolling. In response to the instruction from the change amount adjustment unit 56B, the state change control unit 53B temporarily stops automatic scrolling (S43), or smoothly sets the scrolling speed v of automatic scrolling to zero and stops automatic scrolling ( S43).

  The state change control unit 53B determines whether or not the proximity state management unit 25 has detected a state where the finger FG has hovered in from the state in which the finger FG has hovered during the pause of the automatic scrolling (S44). If the state in which the finger FG is hovering in is not detected during the automatic scrolling pause (S44, NO), the operation of the mobile terminal 300 of this embodiment proceeds to step S35, and step S35. Step S44 is repeated until a touch operation is detected.

The state change control unit 53B resumes automatic scrolling according to the scroll speed stored in the temporary speed holding unit 59 in response to an instruction from the change amount adjustment unit 56B (S45). After step S45, the operation of the mobile terminal 300 of this embodiment returns to step S32.

  On the other hand, the state change control unit 53B continues the automatic scrolling when the hover-in state is not detected from the state where the finger FG is hovering out during the automatic scrolling (S41, NO). The contact operation determination unit 30 determines whether or not the finger FG has performed a touch operation (S46).

When the state change control unit 53B determines that the touch operation determination unit 30 has detected that the finger FG has performed a touch flick operation (S51, YES), the state change control unit 53B starts automatic scrolling (S52). The initial speed of the automatic scroll is calculated by the state change control unit 53B according to the moving speed when the finger FG touches or touches the touch panel TP when the finger FG performs a touch flick operation.

  The state change control unit 53B determines whether or not the scroll speed v of the current automatic scroll is greater than the convergence speed v2 stored in the temporary speed holding unit 59 (S53). When the state change control unit 53B determines that the scroll speed v of the current automatic scroll is greater than the convergence speed v2 stored in the temporary speed holding unit 59 (S53, YES), the scroll speed v is set to the convergence speed v2. It is gradually reduced so as to converge (S54).

In response to an instruction from the change amount adjustment unit 56B, the state change control unit 53B temporarily stops automatic scrolling (S57), or smoothly sets the scrolling speed v of automatic scrolling to zero and stops automatic scrolling ( S57). .

  The state change control unit 53B determines whether or not the proximity state management unit 25 detects that the finger FG hovering in has hovered out during the temporary stop of the automatic scrolling (S58). When the state change control unit 53B detects that the finger FG hovering in has hovered out while the automatic scrolling is temporarily stopped (S58, YES), the state change control unit 53B sets the current scrolling speed (= 0) to the temporary speed. The scroll speed stored in the holding unit 59 is changed (S59). After step S59, the operation of the mobile terminal 300 of this embodiment returns to step S52.

  If it is not detected that the finger FG that was hovering has hovered out during the automatic scrolling pause (S58, NO), the state change control unit 53B continues the automatic scrolling. The contact operation determination unit 30 determines whether or not the finger FG that has been operating the hover has been touched (S60). When it is determined that the finger FG that has been operated by the hover has been touched (S60, YES), the contact operation determination unit 30 notifies the application 50 that the finger FG that has been operated by the hover has been touched. In response to the notification from the contact operation determination unit 30, the state change control unit 53B immediately or smoothly sets the scroll speed v during automatic scrolling to zero and stops automatic scrolling (S61). When the finger FG that has been operated by the hover is not being touched (S60, NO), the operation of the mobile terminal 300 of the present embodiment returns to step S58.

  On the other hand, when the finger FG hovered out is not hovered during the automatic scrolling (S55, NO), the state change control unit 53B continues the automatic scrolling. The contact operation determination unit 30 determines whether or not the finger FG has performed a touch operation (S62).

  When it is determined that the finger FG has been touched (S62, YES), the contact operation determination unit 30 notifies the application 50 that the finger FG has been touched. Thereafter, the operation of the mobile terminal 300 of the present embodiment proceeds to step S61. When the finger FG is not touching (S62, NO), the automatic scrolling is continued, and the operation of the mobile terminal 300 of this embodiment returns to step S52.

  As described above, the mobile terminal 300 according to the present embodiment starts automatic scrolling when it is detected that the finger FG performs a touch flick operation. In addition, when it is detected that the finger FG hovering out during the automatic scrolling is hovered in, the mobile terminal 300 stores the scroll speed in the automatic scroll before the detection in the temporary speed holding unit 59 and automatically scrolls. Pause. In addition, when it is detected that the finger FG that has been operated by hovering during the pause of automatic scrolling has hovered out, the mobile terminal 300 automatically performs the automatic operation according to the scroll speed stored in the temporary speed holding unit 59. Resume scrolling.

  In the automatic scrolling, the convergence speed v2 is maintained when the scroll speed at the time of restart is the convergence speed v2, and is gradually reduced so as to converge to the convergence speed v2 when the scroll speed is higher than the convergence speed v2. .

  Accordingly, the mobile terminal 300 according to the present embodiment can easily start automatic scrolling by performing, for example, a touch flick operation without performing a hover operation (for example, a hover hold operation) for a predetermined time or longer by the finger FG. The operation for starting automatic scrolling can be simplified.

(Sixth embodiment)
In the sixth embodiment, the mobile terminal 300 switches the scroll scroll speed control method according to the initial scroll speed of the inertia scroll when the finger performs a touch flick operation.

(Functional configuration of the mobile terminal 300 of the sixth embodiment)
Since the functional configuration of the mobile terminal 300 of the sixth embodiment is the same as the configuration of the mobile terminal 300 shown in FIG. 8, the description of the same content as the mobile terminal 300 of the third or fourth embodiment is omitted. Or it simplifies and it demonstrates a different content.

  The state change control unit 53B determines whether or not the touch operation determination unit 30 has detected that the finger FG has performed a touch flick operation. When the contact operation determination unit 30 detects that the finger FG has performed a touch flick operation, the state change control unit 53B starts the inertial scroll, and further, the initial scroll speed of the inertial scroll and a predetermined first threshold speed It is compared with a predetermined second threshold speed. The first threshold speed and the second threshold speed are fixed values defined in advance in the operation of the state change control unit 53B, and the first threshold speed is faster than the second threshold speed.

  When it is determined that the scroll initial speed of the inertial scroll is equal to or higher than the first threshold speed, the state change control unit 53B performs inertia while the finger hover operation is detected as in the second embodiment. The scroll speed v is gradually reduced until the scroll speed v reaches the convergence speed v2 after the scroll is interrupted, and after the scroll speed v reaches the convergence speed v2, the scroll is performed with the scroll speed kept constant. To do.

  When the state change control unit 53B determines that the scroll initial speed of the inertial scroll is equal to or higher than the second threshold speed and lower than the first threshold speed, the predetermined time of the finger FG is determined as in the fourth embodiment. Automatic scrolling is started in response to the above hover operation, and when a finger hover operation (for example, a hover hold operation) is detected during automatic scrolling, automatic scrolling is paused. If it is detected that the camera has hovered out, automatic scrolling is resumed. The convergence speed during automatic scrolling is the second threshold speed.

  When the state change control unit 53B determines that the scroll initial speed of the inertia scroll is less than the second threshold speed, the state change control unit 53B executes the conventional inertia scroll.

(Operation of the mobile terminal 300 of the sixth embodiment)
Next, the operation of the mobile terminal 300 of this embodiment will be described with reference to FIGS. FIG. 18 is a graph showing a change with time in scroll speed in the sixth embodiment. FIG. 19 is a flowchart for explaining the operation of the mobile terminal 300 according to the sixth embodiment. In FIG. 18, time t0 is the time when touch flick operation and hover-in are detected at the same time, time t4 is the time when scroll speed v becomes convergence speed v2, time t5 is the time when hover-out is detected, and time t7 is hover. The time when it was detected that the finger FG that was out was hovered in, and the time t8 is the time when it was detected that the finger FG that was hovered out was hovered out. In the description of the flowchart illustrated in FIG. 19, the same operations as those described in the flowcharts illustrated in FIGS. 13 to 15 are denoted by the same reference numerals, and description thereof is omitted or simplified, and different contents are described.

  The scroll curve C8 is the same as the scroll curve C4, the scroll curve C9 is the same as the scroll curve 6 except for the scroll initial speed value, and the scroll curve C10 is the same as the scroll curve C0 except for the scroll initial speed value. Therefore, the description of each scroll curve C8, C9, C10 is omitted.

  In FIG. 19, after step S11, the state change control unit 53B starts inertial scroll, and further compares the scroll initial speed of inertial scroll, a predetermined first threshold speed, and a predetermined second threshold speed (S61). ).

  When the state change control unit 53B determines that the scroll initial speed of the inertial scroll is equal to or higher than the first threshold speed (S61, equal to or higher than the first threshold speed), the hover of the finger FG is performed as in the second embodiment. While the operation is detected, the inertial scroll is interrupted and the scroll speed v is gradually reduced until the scroll speed v reaches the convergence speed v2. After the scroll speed v reaches the convergence speed v2, the scroll speed is kept constant. Scrolling is performed while maintaining

  When the state change control unit 53B determines that the scroll initial speed of the inertial scroll is equal to or higher than the second threshold speed and lower than the first threshold speed (S61, equal to or higher than the second threshold speed and lower than the first threshold speed), As in the fourth embodiment, automatic scrolling is started in response to a hover operation of the finger FG for a certain time or longer, and if a finger hover operation (for example, a hover hold operation) is detected during automatic scrolling, The scrolling is paused, and when the state where the finger is hovered out is detected while the automatic scrolling is paused, the automatic scrolling is resumed.

  However, as described above, in the present embodiment, when the scroll initial speed of the inertial scroll is equal to or higher than the second threshold speed and lower than the first threshold speed, the convergence speed in the fourth embodiment is the second threshold speed. (See the scroll curve C9 shown in FIG. 18).

  If the state change control unit 53B determines that the scroll initial speed of the inertial scroll is less than the second threshold speed (S61, less than the second threshold speed), the state change control unit 53B executes the conventional inertial scroll.

  As described above, the mobile terminal 300 according to the present embodiment switches the scroll scroll speed control method according to the scroll initial speed of the inertia scroll when the finger FG performs a touch flick operation. Further, the mobile terminal 300 according to the present embodiment may select any of the scroll speed control methods in the above-described embodiments according to the scroll initial speed of the inertial scroll when the finger FG performs a touch flick operation.

  Thereby, the mobile terminal 300 according to the present embodiment can execute flexible scrolling according to the user's intention according to the initial speed of inertial scroll when the finger FG performs a touch flick operation.

  Although various embodiments have been described with reference to the drawings, it goes without saying that the present invention is not limited to such examples. It is obvious for those skilled in the art that variations and modifications of various embodiments, and combinations of various embodiments can be conceived within the scope of the claims. Of course, it is understood that it belongs to the technical scope of the present invention.

  The operation of the portable terminal 300 according to the embodiment obtained by combining the first, third, and fourth embodiments described above will be described with reference to FIGS. FIG. 20 is a graph showing a change in scroll speed with time in an embodiment in which the first, third, and fourth embodiments are combined. FIG. 21 is a flowchart for explaining the operation of the mobile terminal 300 in an embodiment in which the first, third, and fourth embodiments are combined. In FIG. 20, a time t0 is a time when a touch flick operation is detected, a time t9 is a time when a finger FG is detected to be hovered in, a time t10 is a time when a certain time has elapsed from the time t0, and a time t5 is a hover-out. The detected time, time t7, is the time when it was detected that the finger FG hovering out was hovered in, and time t8 was the time when it was detected that the finger FG hovering in was hovered out. In the description of the flowchart shown in FIG. 21, the same operations as those in the flowcharts shown in FIGS. 4, 10, and 13 to 15 are denoted by the same reference numerals, and the description is omitted or simplified, and different contents are described. explain.

  In the scroll curve C11, the touch flick operation of the finger FG is detected at time t0 and inertial scrolling starts, hover-in is detected at time t9, and inertial scrolling is interrupted at time t10 when a certain time has elapsed from time t0. Thus, automatic scrolling is started at which the scroll speed is maintained at time t9 when hover-in is detected.

  Further, in the scroll curve C11, since the automatic scrolling is executed after the time t10, the scroll speed is maintained at the scroll speed at the time t9 even if the hover out is detected at the time t5, and the hover out is performed at the time t7. When it is detected that the finger FG is hovered in, the automatic scrolling is temporarily stopped and the scrolling speed becomes zero. When it is detected that the finger FG hovering in at time t8 has hovered out, the automatic scrolling resumes. The scroll speed of the automatic scroll immediately after the restart is the scroll speed of the automatic scroll immediately before time t7.

  In FIG. 21, when the proximity state management unit 25 detects that the finger FG is hovered (S13, YES), the proximity state management unit 25 notifies the application 50 that the finger FG is hovered. Based on the time information output from the timer control unit 80, the state change control unit 53B determines whether or not the finger FG has performed a hover operation for a certain period of time after the touch flick operation (S31).

  If the state change control unit 53B determines based on the time information output from the timer control unit 80 that the finger FG has performed a hovering operation for a certain period of time after a touch flick operation (S31, YES), the process is executed in step S12. The inertial scroll that has been performed is interrupted, and automatic scrolling is started with the scroll speed maintained when it is detected that the finger FG is hovered in (S81). Since the operation after step S81 is the same as that of the fourth embodiment (see FIG. 15), description thereof is omitted.

  On the other hand, when the finger FG has not touched the finger FG for a certain time after the touch flick operation (S31, NO), the state change control unit 53B determines whether the finger FG has been touched (S82). When the finger FG is touch-operated (S82, YES), the operation of the mobile terminal 300 proceeds to step S36. When the finger FG is not touch-operated (S82, NO), the operation of the mobile terminal 300 is step. Return to S12.

  Thereby, the portable terminal 300 can perform automatic scrolling in a state where the scroll speed when the finger FG is hovered in is maintained when a hover operation for a predetermined time or more is detected after the finger FG performs a touch flick operation.

  In the fourth embodiment, the mobile terminal 300 pauses automatic scrolling when it detects that the finger FG has performed a hover hold operation during automatic scrolling. May be accelerated or decelerated. For example, the mobile terminal 300 selects and executes automatic scroll pause, acceleration scroll speed acceleration or deceleration according to the position on the surface of the touch panel TP corresponding to the position where the finger FG performs the hover hold operation. (See FIG. 22A). FIG. 22A is a schematic diagram of a method for controlling the scroll speed in accordance with the position on the surface of the touch panel TP corresponding to the finger FG that is performing the hover hold operation.

  For example, when the finger FG performs a hover hold operation at a height position in the z-axis direction corresponding to the area AR1 of the touch panel TP illustrated in FIG. 22A, the mobile terminal 300 temporarily stops automatic scrolling.

  For example, when the finger FG performs a hover hold operation at a height position in the z-axis direction corresponding to the area AR2 of the touch panel TP illustrated in FIG. 22A, the mobile terminal 300 accelerates the scroll speed of the automatic scroll.

  For example, when the finger FG performs a hover hold operation at a height position in the z-axis direction corresponding to the area AR3 of the touch panel TP shown in FIG. 22A, the mobile terminal 300 decelerates the scroll speed of the automatic scroll.

  Further, the mobile terminal 300 selects and executes automatic scrolling pause, acceleration scrolling acceleration or deceleration depending on the position on the space separated from the surface of the touch panel TP on which the finger FG performs a hover hold operation. (Refer to FIG. 22B).

  For example, when the finger FG performs a hover hold operation from the position of the surface of the touch panel TP (z coordinate = z0 = 0) illustrated in FIG. 22B to the height z1, the mobile terminal 300 temporarily stops automatic scrolling. To do.

  For example, when the finger FG performs a hover hold operation from the surface of the touch panel TP illustrated in FIG. 22B to a position from the height z1 to the height z2, the mobile terminal 300 accelerates the scroll speed of the automatic scroll.

  For example, when the finger FG performs a hover hold operation from the surface of the touch panel TP illustrated in FIG. 22B to a position from the height z2 to the height z3, the mobile terminal 300 reduces the scroll speed of the automatic scroll.

  In each embodiment described above, the mobile terminal 300 may accelerate or decelerate the scroll speed of the automatic scroll when the finger FG performs a hover flick operation during the automatic scroll. Thereby, the portable terminal 300 can perform scrolling suitable for a user's intention on the occasion.
