Description

  The present invention relates to an operation control apparatus that displays a plurality of operation items on a display screen and performs processing corresponding to the operation item by touching a position corresponding to the specific operation item on the display screen. Is.

  The above-described operation control device is put to practical use in, for example, an in-vehicle navigation device that displays a map around a vehicle, sets a route from the departure point of the vehicle to a destination, and performs route guidance according to the route. ing. That is, in the in-vehicle navigation device, various operations including setting of the destination, starting of route guidance, scrolling of the display map, changing the scale of the display map, etc. are performed by touching the operation items displayed on the display screen. To make it feasible.

  Here, in the in-vehicle navigation device, for example, when a destination is determined, there are a number of operation items to be selected, and all operation items may not be displayed at once. Specifically, for example, when setting a destination from a facility type or a genre, there are usually many corresponding facilities. For this reason, the number of facilities to be selected is reduced by narrowing down the area first. This area is narrowed down by specifying prefectures and municipalities. Therefore, even when narrowing down areas, it is not possible to display all prefectures and municipalities at once, so only a part of them is displayed on the screen. Even after the area is narrowed down, there are usually many facilities that fall within the selected area corresponding to the desired facility type and genre. For this reason, the operation item which shows those applicable facilities cannot be displayed at once.

  In this way, when only some operation items are displayed, if the desired operation items are not included in the displayed operation items, the display screen of the operation items can be scrolled or paged. The operation items indicating other facilities and the like are displayed.

  Here, when the operation item display screen is scrolled, for example, a sphere is displayed on the screen, the user's finger or the like is slid on the sphere, and the operation is performed as if the sphere is rotated. It is considered to scroll the display screen in the direction. However, when the user performs an operation of sliding a finger or the like on the screen, there is a possibility that an unintended operation item is accidentally touched. As a result, if a process corresponding to an unintended operation item is executed, the user needs to cancel or perform a selection operation from the beginning, resulting in deterioration of operability. Note that even when a scroll instruction switch that simply instructs scrolling in a certain direction is displayed instead of a sphere, the possibility that the user accidentally touches an unintended operation item is not zero.

  The present invention has been made in view of the above-described points, and it is possible to prevent a process corresponding to an operation item from being executed even when an unintended operation item is touched by a user. Thus, an object of the present invention is to provide an operation control device that allows a user to perform an operation as intended.

In order to achieve the above-described object, an operation control device according to claim 1 is provided:
A display device;
Touch position detection means for detecting a touch position by a user on the display screen of the display device;
The display device displays a plurality of operation items and an operation unit for performing an operation for changing at least some of the plurality of operation items, and is displayed on the display device by the touch position detection unit. Control means for executing processing corresponding to the operation item when it is detected that a touch operation has been performed on any of the plurality of operation items,
The operation unit is configured to scroll a screen on which at least some operation items are displayed in a direction corresponding to the slid direction by sliding the user's touch position on the display screen on the operation unit. When the touch position is repeatedly slid in the same direction on the operation unit, the touch by the user is temporarily non-contact,
The control means treats the touch operation as an invalid operation even if a touch operation is performed on any of the plurality of operation items while the operation unit performs the operation. When a predetermined time has elapsed since the operation to the operation unit was not detected without performing the process, it is considered that the operation by the operation unit has ended, and in response to a touch operation on one of the plurality of operation items, A process corresponding to the operation item is executed .

  When the user performs a touch operation on another operation item while performing an operation on the operation unit, the user performs an operation for changing the operation item displayed on the operation unit and at the same time performs an operation on the operation unit. This means that an item has been selected and execution of processing by the operation item has been instructed. Since it is usually not possible for the user to intentionally perform such an operation, it can be estimated that there is a high possibility that the touch operation on the displayed operation item is erroneously performed. For this reason, in the operation control apparatus according to the first aspect, even if a touch operation is performed on any of the operation items while the operation by the operation unit is performed, the operation is regarded as an invalid operation. Thereby, even if a touch operation is performed on an operation item not intended by the user, it is possible to prevent the process corresponding to the operation item from being executed.

Then , as the operation unit, by sliding the user's touch position on the display screen on the operation unit, the screen on which at least some operation items are displayed is scrolled in a direction corresponding to the slid direction. be those repeatedly when sliding the touch position in the same direction, Ru have use those temporarily becomes touch by the user without contact. By using such an operation unit, the user's operational feeling can be improved. And, when the operation on the operation unit is to slide the user's touch position on the operation unit, in particular, there is a high possibility of accidentally touching other operation items displayed on the display screen. so that the effectiveness of the operation control device is more remarkably exhibited.

Furthermore, the control means considers that the operation to the operation unit has ended when a predetermined time has elapsed since the operation to the operation unit was not detected, and in response to a touch operation to any of the plurality of operation items, A process corresponding to the operation item is executed. In order to confirm the operation item newly displayed by scrolling, the user temporarily makes no contact with the operation unit, or when the operation unit is a sphere, repeatedly put a finger or the like in the same direction. In order to make it slide, a finger | toe etc. may be temporarily removed from an operation part. Even if the operation unit on the screen becomes non-contact in this way, the operation of the operation unit may be resumed immediately, so when a predetermined time has elapsed since the operation to the operation unit was not detected, It is considered that the operation by the operation unit has been completed.

  Hereinafter, an embodiment in which an operation control device of the present invention is applied to an in-vehicle navigation device will be described with reference to the drawings. However, the operation control device according to the present invention is not limited to the in-vehicle navigation device, but can be applied as an operation control device for other devices.

  FIG. 1 is a block diagram showing a schematic configuration of an in-vehicle navigation device according to this embodiment. As shown in the figure, the in-vehicle navigation device 100 of this embodiment includes a position detector 1, a map data input device 6, an operation switch group 7, an external memory 9, a display device 10, an audio output device 11, and a remote control sensor 12. And a control circuit 8 connected thereto.

  The control circuit 8 is configured as a normal computer, and includes a well-known CPU, ROM, RAM, I / O, and a bus line for connecting these configurations. In the ROM, a program to be executed by the in-vehicle navigation device 100 is written, and a CPU or the like executes predetermined arithmetic processing according to this program.

  The position detector 1 includes a well-known geomagnetic sensor 2, a gyroscope 3, a vehicle speed (distance) sensor 4 for calculating a travel distance, and a GPS (Global Positioning) that detects the position of the vehicle based on radio waves from a satellite. System) GPS receiver 5 is included. Since these have errors of different properties, they are configured to be used while being complemented by a plurality of sensors. Depending on the accuracy of each sensor, the position detector 1 may be constituted by a part of the above.

  The map data input device 6 is a device for inputting map data such as so-called map matching data, map drawing data, route search data and the like for improving position detection accuracy. These databases are generally stored in a read-only storage medium such as a CD-ROM or DVD-ROM, but may be stored in a writable storage medium such as a memory card or hard disk. .

  The operation switch group 7 has a touch panel sensor integrated with the display device 10 and cooperates with an operation item image displayed on the screen of the display device 10 to search for a desired map or facility by scrolling the map. Are used for various input operations such as inputting characters and numbers and selecting displayed operation items. As this touch panel sensor, various types such as a resistive film method, an ultrasonic surface acoustic wave method, an infrared light shielding method, a capacitance method, an electromagnetic induction method and the like are known. The touch panel sensor can be used.

  For example, a resistive film type touch panel sensor has a glass substrate with electrodes arranged in a grid and a flexible film arranged opposite to each other via a spacer. When the user touches the flexible film, electricity flows through the electrode corresponding to the position. At that time, the user's touch position can be detected by measuring the voltage division ratio due to the resistance of the grid electrode.

  The external memory 9 is, for example, a large capacity readable / writable storage medium such as a memory card or HDD, and is used for storing various data such as text data, image data, and audio data.

  The display device 10 is configured by a liquid crystal display. The screen of the display device 10 is generated by the processing of the control circuit 8 using the vehicle position mark corresponding to the current position of the vehicle input from the position detector 1 and the map data input from the map data input device 6. A map around the vehicle can be displayed. Further, the display device 10 has various menus for making various settings of the in-vehicle navigation device 100, selecting a function to be executed such as destination setting, and an area area for setting a desired destination. A plurality of operation item images for narrowing down and selecting a facility to be a destination are displayed.

  FIG. 2 shows an example of a display screen when setting the destination. The example shown in FIG. 2 is displayed when “meal” is selected as the genre and a facility where meals can be made is set as the destination. As shown in FIG. 2, in this embodiment, in order to narrow down the types of facilities for eating, in addition to a plurality of operation items 20 to 24 indicating each facility type, operation items 20 to 20 indicating the facility type displayed on the screen. An operation unit (trackball) 30 for changing 24 is displayed.

  The trackball 30 slides the user's finger or the like on the trackball 30 and performs an operation as if the trackball 30 is rotated, so that the display screen on which the operation items 20 to 24 are displayed is displayed in the rotation direction. To scroll. By using such a trackball 30 as the operation unit, it is possible to improve the user's operational feeling.

  However, when the user performs an operation of sliding a finger or the like on the screen so as to rotate the trackball 30, there is a possibility that the unintended operation items 20 to 24 may be accidentally touched. As a result, if processing corresponding to the operation items 20 to 24 not intended by the user is executed, the user needs to cancel or perform the selection operation from the beginning, resulting in deterioration in operability.

  For this reason, in the present embodiment, when the trackball 30 is operated, even if any of the operation items 20 to 24 is touched by executing a control process shown in FIG. The operation corresponding to the corresponding operation items 20 to 24 is not performed. Thereby, the user can perform a desired operation, and the operability when the touch panel sensor is used can be improved.

  In FIG. 2, 31 and 34 are scroll instruction switches in the return direction and the forward direction, and 32 and 33 are page return and page feed switches that instruct to scroll the display screen in units of pages.

  Next, a control process executed when the trackball 30 is operated will be described in detail based on the flowchart of FIG. Note that the processing shown in the flowchart of FIG. 3 is executed at predetermined time intervals.

  First, in step S100, based on a detection signal from the touch panel sensor, it is determined whether or not the user has started an operation for scrolling the display screen of the operation items 20 to 24 on the image of the trackball 30. . When it is determined “No” in the determination process of step S100, the process illustrated in FIG. 3 ends. On the other hand, if “Yes” is determined in step S100, the process proceeds to step S110. In step S110, the touch operation on the image of the operation item other than the trackball 30 is invalidated. In order to invalidate the touch operation, for example, even if a signal indicating a touch operation on the image display area of an operation item other than the trackball 30 is output from the touch panel sensor, the control circuit 8 performs the touch operation. The execution of the processing based on it may be prohibited. In addition, for example, a signal indicating a touch operation with respect to an image display area of an operation item other than the trackball 30 may be set not to be output from the touch panel sensor.

  Next, in step S120, the display images of the operation items 20 to 24 are scrolled in the direction corresponding to the rotation direction of the trackball 30. As a result, the displayed operation items 20 to 24 disappear from the display screen in order, and new operation items are displayed. Thus, the user can display a desired operation item by scrolling the display screen by performing an operation on the trackball 30.

  In step S130, it is determined based on the detection signal from the touch panel sensor whether or not an operation on the trackball 30 has been detected. If it is determined that an operation on the trackball 30 is detected, the process returns to step S120. On the other hand, if it is determined that the operation on the trackball 30 has not been detected, the process proceeds to step S140. In step S140, it is determined whether or not a predetermined time has elapsed since the operation on the trackball 30 was not detected. At this time, if it is determined that the predetermined time has not yet elapsed, the process proceeds to step S150 to determine whether or not the operation on the trackball 30 has been resumed. In the determination process of step S150, if it is determined that the operation has been resumed, the process returns to step S120. If it is determined that the operation has not been resumed, the process returns to step S140. It is determined again whether a predetermined time has passed since the detection.

  Thus, if it is determined in step S140 that a predetermined time has elapsed since the operation on the trackball 30 was not detected, the process proceeds to step S160. In step S160, it is considered that the operation on the trackball 30 has been completed, and the touch operation on the image indicating the operation items other than the trackball 30 is validated. Thereby, the process corresponding to the operation item 20-24 is performed by the touch operation to one of the operation items 20-24.

  As described above, in this embodiment, it is determined that the operation on the trackball 30 is completed after a predetermined time has elapsed since the operation on the trackball 30 was not detected. In order to confirm the operation item newly displayed by scrolling, the user temporarily makes no contact with the trackball 30 or repeatedly slides a finger or the like on the trackball 30 in the same direction. In some cases, a finger or the like is temporarily removed from the trackball 30. In such a case, even if the operation on the image of the trackball 30 is not detected, the operation on the trackball 30 is not necessarily completed, but the operation on the trackball 30 is only temporarily interrupted. is there. Accordingly, in order to determine whether or not the operation on the trackball 30 has been completed, it is assumed that the operation on the trackball 30 has been completed when a predetermined time has elapsed since the operation on the trackball 30 was not detected. It is preferable to regard it.

  According to the embodiment described above, the trackball 30 performs an operation for changing at least some of the operation items 20 to 24 among the plurality of operation items 20 to 24 and 31 to 34 displayed on the display device 10. Even if a touch operation is performed on any of the plurality of operation items 20 to 24 and 31 to 34 while the operation is being performed, the touch operation is regarded as an invalid operation, and the operation item is handled. No processing is performed. Thereby, even if a touch operation is performed on an operation item not intended by the user, it is possible to prevent the process corresponding to the operation item from being executed. As a result, the user can perform the desired operation, and the operability when using the touch panel sensor can be improved.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  In the embodiment described above, an example has been described in which, when the trackball 30 is operated as the operation unit, even if a touch operation is performed on an image indicating other operation items, the touch operation is regarded as an invalid operation. However, the operation unit is not necessarily limited to the trackball 30, and the present invention can be applied as long as it scrolls the display screen. For example, using the scroll instruction switch, page return or page feed switch shown in FIG. 2 as the operation unit, touch operations on other operation items may be invalidated when these switches are operated. This is because even when the scroll instruction switch or the page return or page feed switch shown in FIG. 2 is operated, a touch operation on another operation item may be erroneously performed.

  In the above-described embodiment, direct execution of touching each operation item instructs the execution of processing by a desired operation item. However, for example, when the cursor that matches any of the operation items is moved by the operation unit, and the execution determination switch displayed on the screen is operated, the processing by the operation item that matches the cursor May be executed. In this case, if the operation item to which the cursor is moved is not displayed when the cursor is instructed to move, the cursor is moved while scrolling the screen so that the undisplayed operation item is displayed on the display screen. Should be done.

It is a block diagram which shows schematic structure of the vehicle-mounted navigation apparatus concerning this embodiment. It is explanatory drawing which shows an example of the display screen at the time of the setting of the destination. It is a flowchart which shows the control processing when the trackball 30 is operated.
