In this way, a slide operation in a downward direction, in which a slide operation can be performed relatively smoothly, can scroll the list both downward and upward, thereby allowing a user to smoothly perform both upward and downward scrolling.

Description

  The present invention relates to a scroll control device and a scroll control method, and is particularly suitable for use in a device that controls scrolling of a list by a tracing operation of a touch panel.

  In recent years, in-vehicle devices such as a car navigation device and a car audio device are increasingly using a touch panel as an operation means. In this type of in-vehicle device, various operations of the in-vehicle device can be instructed by a user's touch operation or tracing operation on a user interface displayed on a display with a touch panel (hereinafter simply referred to as a touch panel). (For example, refer to Patent Document 1).

  In Patent Document 1, when a sphere is displayed on a touch panel as a user interface and an operation to rotate the sphere is performed, the focus on the button group displayed in the list format in the vertical direction is set to the rotation of the sphere. It is described that they are moved together. Specifically, when the user operates the sphere to roll upward on the screen, the focus is moved upward. On the other hand, when the user operates the sphere to roll downward on the screen, the focus is moved downward.

  As described above, when a list is scrolled by a tracing operation on the touch panel, it is common to trace the touch panel upward when scrolling the list upward and to trace the touch panel downward when scrolling downward. By the way, in the case of an in-vehicle device, the touch panel is fixed near the center console, and the posture when the user operates the touch panel from the driver seat or the passenger seat is almost determined. In addition, the touch panel is installed in an upright state in order to make the display screen easier to see.

  For this reason, when the touch panel is traced downward, the touch panel can be operated relatively smoothly. However, when the touch panel is traced upward, the finger is easily caught and the trace operation is difficult to perform. Usually, each item in the list is often displayed in ascending order from the top. Therefore, in many cases, the touch panel is traced upward in order to scroll the list upward. However, it is difficult to perform the upward tracing operation, and scrolling may not be performed well.

  The present invention has been made to solve such a problem, and it is an object of the present invention to make it easy to perform an operation when scrolling upward when scrolling by touching a touch panel.

  In order to solve the above-described problem, in the present invention, when a drag operation is performed in one direction in the first area on the image displayed on the touch panel, the list is scrolled in one direction, while the second When the tracing operation is performed in one direction in the area, the list is controlled to be scrolled in a direction different from the one direction.

  According to the present invention configured as described above, when the list is scrolled in one direction or scrolled in a direction different from the one direction, it is only necessary to perform the tracing operation in the same one direction in different regions. This eliminates the need to change the direction of the tracing operation in accordance with the scrolling direction. As a result, if one direction is set in a direction in which the tracing operation can be performed relatively smoothly, the tracing operation can be easily performed when scrolling the list in any direction, and the scrolling can be performed smoothly. Will be able to.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a functional configuration example of the scroll control device according to the present embodiment. In addition, the scroll control apparatus of this embodiment is mounted in in-vehicle apparatuses, such as a car navigation apparatus and a car audio apparatus, for example.

  As shown in FIG. 1, the scroll control device of the present embodiment includes an image display control unit 11, an operation detection unit 12, and a scroll control unit 13 as functional configurations. Each of these functional configurations 11 to 13 can be realized by any of a hardware configuration, a DSP, and software. For example, when realized by software, each of the functional configurations 11 to 13 includes a computer CPU or MPU, RAM, ROM, and the like, and can be realized by operating a program stored in the RAM or ROM.

  The image display control unit 11 displays an image including a list on a display with a touch panel (hereinafter simply referred to as a touch panel 20). The image displayed here is, for example, an image formed by rendering the loop shape three-dimensionally so that the front surface and the back surface of the loop appear and arranging the items of the list in the vertical direction on the front surface of the loop. .

  FIG. 2 is a diagram illustrating a specific example of an image displayed by the image display control unit 11. As shown in FIG. 2, in this embodiment, a cylindrical drum 100 is displayed as an example of a loop shape. Specifically, the drum 100 is represented as a three-dimensional perspective view so that the front surface 101 and the rear surface 102 appear, and the list items are displayed on the front surface 101 of the drum side by side in the vertical direction. Of the entire area of the touch panel 20, an area where the front surface 101 of the drum 100 is displayed corresponds to a “first area” in the claims, and an area where the back surface 102 of the drum 100 is displayed is as claimed. This corresponds to the “second region”.

  The operation detection unit 12 detects a tracing operation on the touch panel 20. The scroll control unit 13 controls the scrolling of the list displayed on the surface 101 of the drum 100 according to the tracing operation detected by the operation detection unit 12. FIG. 3 is a diagram for explaining the scroll operation of the present embodiment controlled by the scroll control unit 13.

  As shown in FIG. 3A, the scroll control unit 13 performs a downward drag operation on the touch panel 20 as indicated by an arrow A in the first area where the surface 101 of the drum 100 is displayed. When the operation is detected by the operation detection unit 12, the list is scrolled downward as indicated by an arrow B. That is, the tracing operation in this case corresponds to an operation of rotating the outside of the drum 100 downward, so that the drum 100 rotates forward and the list displayed on the outside of the drum 100 scrolls downward.

  On the other hand, as shown in FIG. 3B, the scroll control unit 13 performs a downward drag operation on the touch panel 20 as indicated by an arrow C in the second area where the back surface 102 of the drum 100 is displayed. When the operation detection unit 12 detects that the operation has been performed, the list is scrolled upward as indicated by an arrow D. That is, the tracing operation in this case corresponds to an operation of turning the inside of the drum 100 downward, so that the drum 100 rotates in the reverse direction and the list displayed on the outside of the drum 100 scrolls upward.

  FIG. 4 is a flowchart showing an operation example of the scroll control device according to the present embodiment configured as described above. The flowchart shown in FIG. 4 starts when the user instructs display of an image including a list. For example, when the scroll control device of the present embodiment is mounted on a car navigation device, the processing of the flowchart shown in FIG. 4 starts when an instruction to set a destination is given by a list operation. Alternatively, when the scroll control device according to the present embodiment is mounted on a car audio device, the processing of the flowchart shown in FIG.

  First, the image display control unit 11 displays an image including a list as shown in FIG. 2 on the touch panel 20 (step S1). Next, the operation detection unit 12 determines whether or not a tracing operation on the touch panel 20 has been performed (step S2). If the tracing operation has not been performed, the process returns to step S1.

  On the other hand, when the operation detecting unit 12 detects the tracing operation on the touch panel 20, the scroll control unit 13 determines whether or not the tracing operation has been performed on the surface 101 of the drum 100, that is, the first region (step S3). ). Here, when it is determined that the operation is the tracing operation on the surface 101 of the drum 100, the scroll control unit 13 performs control so that the list is scrolled in the same direction as the direction (upward or downward) of the tracing operation (step S4). ).

  That is, if the direction of the tracing operation is downward, the direction of the scroll is also downward, and if the direction of the tracing operation is upward, the direction of the scroll is also upward. Note that the touch panel 20 used in the in-vehicle device is installed in a state of standing substantially vertically in the vicinity of the center console, and thus it is difficult to perform an operation of tracing upward. Therefore, it is recommended that the tracing operation on the surface 101 of the drum 100 is performed downward.

  When it is determined in step S3 that the operation is not the tracing operation on the front surface 101 of the drum 100, the scroll control unit 13 determines whether or not the tracing operation has been performed on the rear surface 102 of the drum 100, that is, the second region. (Step S5). Here, when it is determined that the operation is the tracing operation on the back surface 102 of the drum 100, the scroll control unit 13 performs control so that the list is scrolled in a direction opposite to the direction of the tracing operation (step S6).

  That is, if the direction of the tracing operation is downward, the scroll direction is upward, and if the direction of the tracing operation is upward, the scroll direction is downward. As described above, since it is difficult to perform an operation of tracing the touch panel 20 upward, it is recommended that the tracing operation on the back surface 102 of the drum 100 is also performed downward. In short, in the present embodiment, if the user performs a tracing operation in a downward direction that is easy for the user to trace, the list can be scrolled downward or upward depending on the operation position.

  When it is determined in step S5 that the operation is not the tracing operation on the back surface 102 of the drum 100, the tracing operation is performed in a portion other than the area where the drum 100 is displayed on the screen. In that case, other processing corresponding to the user interface displayed in the area where the tracing operation has been performed is executed (step S7). By executing any one of steps S4, S6, and S7, the process of the flowchart shown in FIG. 4 ends.

  As described above in detail, in the present embodiment, when a downward drag operation is performed in the region of the surface 101 in the image of the drum 100 displayed on the touch panel 20, the list is scrolled downward. On the other hand, when the tracing operation is performed downward in the area of the back surface 102 of the drum 100, the list is scrolled upward.

  According to the present embodiment configured as described above, the scroll operation may be performed in the same downward direction in the area of the front surface 101 or the back surface 102 of the drum 100, regardless of whether the list is scrolled downward or scrolled upward. It is not necessary to change the direction of the tracing operation in accordance with the direction of. Since the downward tracing operation is a direction in which the tracing operation can be performed relatively smoothly, the tracing operation can be easily performed even when the list is scrolled in either the upper or lower direction.

  Moreover, according to the present embodiment, since the scroll direction of the list coincides with the rotation direction of the drum 100, the user can determine which direction the list is scrolled by operating either the front surface 101 or the back surface 102 of the drum 100. Has the merit of being able to grasp intuitively.

  In the above-described embodiment, an example has been described in which the items of the list are drawn in the vertical direction and the list is scrolled in the vertical direction. However, the present invention is not limited to this. For example, the drawing may be performed with the drum 100 shown in FIG. 2 rotated 90 degrees, and the list items may be drawn side by side on the surface 101, and the list may be scrolled in the left-right direction. .

  In this case, for example, the scroll control unit 13 scrolls the list to the right when the tracing operation is performed to the right in the area where the front surface 101 of the drum 100 is displayed, while the rear surface 102 is displayed. When a tracing operation is performed in the right direction, the list is controlled to scroll leftward. This is because, when operating from the driver's seat on the right side of the touch panel 20, it can be operated relatively smoothly when tracing to the right, but when tracing to the left, the finger is easily caught and the tracing operation is difficult to perform.

  Moreover, although the said embodiment demonstrated the example which displays the cylindrical drum 100 as an example of loop shape, this invention is not limited to this. For example, as shown in FIG. 5, a loop shape such as a belt conveyor 200 may be displayed, and a list may be displayed on the surface 201 thereof. Also in this case, the list is scrolled downward when the area of the front surface 201 of the belt conveyor 200 is dragged downward, and the list is scrolled upward when the area of the back surface 202 is traced downward.

  Moreover, although the said embodiment demonstrated the example which makes the image displayed on the touch panel 20 the image of a loop shape, this invention is not limited to this. That is, a first area and a second area different from the first area are set on the image displayed on the touch panel 20, and the scroll direction depends on which area the tracing operation is performed in one direction. The image to be displayed is not limited to the loop-shaped image as long as the image is changed.

  For example, as shown in FIG. 6, the first area 301 is set on the left side of the normal list 300 in which the items are arranged in a plane in the vertical direction, and the second area 302 is set on the right side of the list 300. To do. Then, the list 300 is scrolled downward when a downward operation is performed in the first area 301, while the list 300 is scrolled upward when a downward operation is performed in the second area 302. You may control.

  In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.
