Description

  The present invention relates to a navigation apparatus capable of performing an intuitive drag operation with an inexpensive system by adjusting a drag operation determination method, a drawing timing, and a drawing method.

  For example, in a car navigation device, a display device including a liquid crystal display provided in a passenger compartment (center part of the instrument panel) displays a map around the current driving position of the host vehicle and various input setting screens (selection screens). Etc. are to be displayed. A touch panel (touch screen) is provided on the screen of the display device, and when the user directly touches various selection items (icons and character keys) set on the selection screen, for example, the destination Various selections and settings such as search / setting, change of scale of map display, and input instruction are performed.

  In the touch panel operation, when the screen size is small, the size of items (operation buttons (minimum operation area)) that can be reliably instructed by a human finger is almost determined, and items (lists) displayed both vertically and horizontally on the display screen. However, there is a limit, and if there are many items to be displayed, it is difficult to operate with human fingers. For this reason, an operation button for scrolling items is provided on a part of the display screen, and in order to change the item displayed on the display screen, the operation of a human finger is performed by operating the scroll operation button, dragging or flicking. An invention is disclosed in which items are changed in accordance with (see, for example, Patent Document 1).

Next, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a hardware configuration of the navigation device according to the first embodiment of the present invention.

  As shown in FIG. 1, the configuration of the navigation device 1 of the present invention includes a control unit 2, a touch input unit 3, a storage unit 4, a RAM 5, a display unit 6, a ROM 7, and a bus line 8. Configured.

  The control unit 2 can control the operation of each unit constituting the navigation device 1, and also includes a touch coordinate history storage unit 2a, a list information acquisition unit 2b, a drag detection unit 2c, a list scroll determination unit 2d, and a list redisplay unit 2e. It is configured with.

Here, the touch coordinate history storage unit 2 a is configured to acquire the coordinates input by the touch input unit 3 and store the history in the storage unit 4.
The list information acquisition unit 2b acquires display information of a list to be displayed as a list, for example, the size and display coordinate row of the outer frame of the list, and the maximum display number and row and column size and display coordinates of the column. It is configured to be able to.

The drag detection unit 2c is characterized in that it can determine the direction of the drag operation by calculating the distance, direction, and speed of movement from the touch coordinate history in the touch coordinate history storage unit 2a.
The list scroll determination unit 2d compares the width of one row and one column of the current list acquired from the list information acquisition unit 2b with the drag movement distance calculated by the drag detection unit 2c, updates the list information, and scrolls. It is comprised so that it can be determined.

  When the drag detection unit 2c detects a drag operation, the list redisplay unit 2e acquires information on the list that is currently displayed from the list information stored in the storage unit 4, and determines the width of one line of the list information. The movement distance dragged from the previous list scroll is acquired by the list information acquisition unit 2b to determine whether the list scroll is necessary. When it is determined that the list scroll is necessary, the list frame does not update the display. Only the characters and icon information displayed in the list are updated in the direction in which one row or one column is dragged.

  The touch input unit 3 is configured to be used for user operation and data input to the navigation device 1.

  The storage unit 4 is generally a recording medium represented by an HDD (Hard Disk Drive), and stores a list information database of the navigation device 1, and map data necessary for navigation is stored in the storage medium. The recorded map data can be read out and transferred to the RAM 5.

  The RAM 5 is configured to be able to store information transferred from each component of the navigation device 1 and to delete information as necessary.

  The display unit 6 is configured to be able to display a map and a list of search results in the navigation device 1, and specifically includes a liquid crystal display or the like. The display unit 6 can be integrated with the touch input unit 3 and can be configured as a touch panel type display unit that selects and inputs information and items displayed on the display unit 6 with a touch panel.

  The ROM 7 stores a computer program that defines the operation of the navigation device 1.

  The bus line 8 is configured so that the components constituting the navigation device 1 can be communicably connected.

The operation of the navigation device 1 configured as described above will be described using a flowchart. FIG. 2 is a flowchart showing list scroll processing when a drag operation is performed during list display in the navigation device of the present invention.
First, list scroll processing in the navigation device 1 of the present invention will be described with reference to the flowchart of FIG.

  As shown in FIG. 2, when the navigation apparatus 1 of the present invention touches the touch panel, it acquires the coordinates of the touch position from the touch input unit 3, and can know which part is displayed on the display unit 6 (S1). ). The drag detection unit 2c detects the drag operation using the coordinates of the touch position acquired in S1 and the touch coordinates of the history of the touch coordinate history storage unit 2a stored in the storage unit 4 (S2). As a result of detecting the drag operation in S2, it is determined whether or not the drag operation is being performed (S3). If it is determined in S3 that the drag operation is not being performed (S3, NO), the flow is ended. If it is determined that a drag operation is being performed in S3 (S3, YES), information on the list currently displayed is acquired from the list information stored in the storage unit 4 (S4), and the list information acquired in S4 Is calculated using the list information acquisition unit 2b to determine whether the list scroll is necessary (S5). As a result of determining whether or not the list scroll is necessary in S5, if it is determined that the list scroll is not necessary (S6, NO), the flow ends. If it is determined in S6 that list scrolling is necessary, the list redisplay unit 2e does not update the display of the list frame, and only the character or icon information displayed in the list is dragged in one line or column. The display is updated (S7), and the flow ends.

  Next, a specific operation of the navigation device 1 configured as described above will be described with reference to the drawings. 3 to 5 are schematic diagrams illustrating the operation of the operation input device according to Embodiment 1 of the present invention.

  As shown in FIG. 3, when there are more than one list screen candidates for list display in the navigation device 1 (FIG. 3), the list display of the maximum number of displays is performed on the navigation display device as shown in FIG. 4. (FIG. 4). At this time, the width of one line of the list is y. In the list display state of FIG. 4, when a drag operation is performed downward by touching the fingertip on the arrow portion, it is determined whether a drag distance greater than or equal to y of the list width has been performed, and the list width y is determined. When the above drag width is confirmed, as shown in FIG. 5, the display position of the list frame is not changed, and only the display contents in the list are updated and the list can be scrolled. Since only the display contents in the list are updated, the processing is easier than redrawing the entire list frame, and the user of the navigation device 1 seems to have moved the list frame by performing a drag operation. Can make you feel the processing.

  It is a navigation device with touch input, and is a technology that realizes list scrolling by comparing the distance of the drag and the width of the list when a drag operation is performed during list display, and requires a drag operation in an inexpensive system It is useful as a portable navigation device and a car navigation device.
