  Further, the control unit 21 of the present embodiment has a route creation function, creates a route for reaching the destination from the departure point based on information such as marks stored in advance, and automatically creates the route. It can be displayed on the display unit 24 together with the ship position.

  As described above, the control unit 21 according to the present embodiment performs an application that performs processing related to the antenna unit 10 and the radar image, an application that displays data in a configuration according to the setting of the user, and processing related to the electronic chart and the route. The application is configured to be executable. And the control part 21 is comprised so that switching from which application the information image from the display part 24 is displayed according to a user's selection.

  Next, the contents displayed on the display unit 24 and the operation method thereof will be described with reference to FIGS. 3 and 4 are diagrams showing display contents of the display unit 24 when the application to be displayed is ECDIS (an application that performs processing relating to electronic charts and routes). FIG. 5 is a diagram illustrating display contents of the display unit 24 when the application is switched from ECDIS to RADAR (an application that performs processing related to the antenna unit 10 and the radar image). 6 and 7 are diagrams showing display contents of the display unit 24 when the display target application is RADAR.

  As shown in FIG. 3A and the like, the display contents of the display unit 24 include an application display unit 30 and a first menu item display in addition to an electronic chart or radar image as an information image displayed largely in the center of the screen. The unit 31 includes a second menu item display unit 32, a common menu item display unit 35, and a voyage data display unit 36. In addition, as shown in FIG. 4, the third menu item display unit 33 or the fourth menu item display unit 34 may be temporarily displayed on the display unit 24.

  First, a case where the display target application is ECDIS will be described.

  The application display unit 30 is disposed in the upper left corner of the screen. The application display unit 30 indicates from which application the information image is currently displayed. When switching the application to be displayed (for example, switching from ECDIS to RADAR), the user operates the trackball 52 to move the pointer 37 and clicks the application display unit 30. Then, as shown in FIG. 5A, a list of applications is displayed below the application display unit 30. The list and the application display unit 30 constitute an application selection menu 30a. Then, the user moves the pointer 37 to RADAR that is an application to be displayed. At this time, as shown in FIG. 5A, a frame-like cursor is displayed on the RADAR with the pointer 37 (see FIG. 5A). By clicking in this state, the application to be displayed can be switched from ECDIS to RADAR (see FIG. 5B). Note that the configurations of the application display unit 30 and the application selection menu 30a are common among applications to be displayed. An application selection method (such as a device used for selection and a selection procedure) is also common among applications to be displayed.

  The first menu item display unit 31 is arranged in an elongated area along the edge of the screen (upper end portion of the display unit 24) from the upper left corner of the screen (screen corner where the application name is displayed). In the first menu item display unit 31, the first menu items are displayed side by side in the left-right direction. The first menu item is a menu item used in the application displayed on the application display unit 30. In this embodiment, applications (ECDIS, RADAR, etc.) with many menu items are used, and therefore, hierarchical menus are set in these applications. The first menu item display unit 31 displays all menu items corresponding to the highest hierarchy of the hierarchical menu.

  When the user selects the first menu item, the user first operates the trackball 52 to move the pointer 37 to the desired first menu item. At this time, a frame-like cursor is displayed on the first menu item with the pointer 37 (see FIG. 3A). Then, the first menu item can be selected by clicking in this state. The selected first menu item is displayed so that the display color is different from that of the other first menu items (for example, the color is inverted) (see FIG. 3B).

  The second menu item display unit 32 is arranged in an elongated area along the edge of the screen (the left end portion of the display unit 24) from the upper left corner of the screen (the screen corner where the application name is displayed). In the second menu item display section 32, the second menu items are displayed side by side in the vertical direction. That is, the application selection menu 30a is displayed at a position where the arrangement direction of the first menu item and the arrangement direction of the second menu item intersect. In the second menu item display section 32, all menu items in the hierarchy immediately below the first menu item selected as described above are displayed side by side in the same direction as the second menu item. That is, as shown in FIGS. 3A and 3B, different second menu items are displayed on the second menu item display unit 32 in accordance with the selection of the first menu item. The second menu item includes a menu item (third menu item) that is lower than the second menu item and a menu item that does not exist, and is displayed so that they can be distinguished from each other. In the present embodiment, a triangular identification mark is displayed at the lower right of the frame only for the second menu item in which the lower third menu item exists, and thereby the user determines the presence or absence of the third menu item. be able to.

  When the user selects the second menu item, the frame-shaped cursor displayed on the second menu item display unit 32 is moved by rotating the operation knob 51 to match the desired second menu item. In this state, the second menu item can be selected by pressing the operation knob 51. The user can cause the control unit 21 to perform the selected work and setting by selecting the second menu item on which the identification mark is not displayed. Further, the user can display the third menu item display section 33 by selecting the second menu item on which the identification mark is displayed (see FIG. 4A).

  The second menu item display unit 32 is normally displayed at all times. Therefore, for example, when there is a frequently used first menu item, the lower second menu item can be selected without selecting the first menu item each time. The second menu item display unit 32 can be hidden according to the operation of the operation unit 23.

  As shown in FIG. 4A, the third menu item display unit 33 is not normally displayed in order to prevent overlapping with an electronic chart or the like, and only when the second menu item on which the identification mark is displayed is selected. Are displayed in an elongated area extending to the right from the second menu item display section 32. In the third menu item display unit 33, the third menu items below the selected second menu item are arranged side by side in the left-right direction (the same direction as the direction in which the first menu items are arranged). Similarly to the second menu item, an identification mark is displayed at the lower right of the frame only for items having a menu item lower than the third menu item (fourth menu item). Has been. The selection of the third menu item display unit 33 is performed using the trackball 52 as in the selection of the first menu item.

  The user can cause the control unit 21 to perform the selected work and setting by selecting the third menu item on which no identification mark is displayed. In addition, the user can display the fourth menu item display unit 34 by selecting the third menu item on which the identification mark is displayed (see FIG. 4B). The third menu item is configured not to be displayed after the third menu item is selected or the fourth menu item associated with the third menu item is selected.

  In the fourth menu item display unit 34, the fourth menu items associated with the selected third menu item are arranged side by side in the vertical direction (the same direction as the direction in which the second menu items are arranged). The selection of the fourth menu item display unit 34 is performed using the trackball 52 as in the selection of the first menu item.

  In this embodiment, the arrangement of menu items is the same regardless of the application to be displayed, and the contents of the menu items are changed according to the application. Therefore, the operational feeling can be unified among a plurality of applications. In addition, as shown in FIG. 5A and the like, the display unit 24 of the present embodiment includes an application selection menu 30a and an information image (electronic chart, etc.) created by executing the selected application. Menu items (first to fourth menu items) used in the application can be displayed simultaneously.

  In the present embodiment, menu items are selected as described above. In the above, the operation knob 51 is used only for selecting the second menu item, and the trackball 52 is used for other selections. Thereby, since it is not necessary to move the pointer 37 largely after selecting the first menu item, the second menu item can be selected quickly. The menu item selection method can be arbitrarily set. For example, the menu item other than the second menu item can be selected using the operation knob 51, and the second menu item can be selected using the trackball 52. Various settings can be changed.

  As the selection operation unit, for example, an external mouse can be used instead of the trackball 52. In addition, a configuration including a direction key and a determination key can be used as the selection operation unit.

  The common menu item display unit 35 is arranged at the lower side of the screen than the second menu item. The common menu item display unit 35 displays common menu items that are menu items used in common among different applications. The common menu item display unit 35 is configured so that the position does not change even when the application is switched (see FIG. 5). Therefore, the operational feeling among a plurality of applications can be unified.

  Specific examples of the process performed for the common menu item include a process for canceling the operation and returning it to the original state, a process for adjusting the display color of the screen, and the like.

  The navigation data display unit 36 displays information corresponding to the application (such as setting information regarding the route in the case of ECDIS) and information (such as ship speed, position, and heading) that is always displayed regardless of the application. Is done.

  Next, a specific example of menu items when the application is ECDIS will be briefly described. In ECDIS, for example, “route monitoring”, “route planning”, “nautical chart management”, and the like are set as the first menu items. “Route monitoring” is a menu item for performing settings relating to display of the set route. “Route plan” is a menu item for setting a route. “Nautical chart management” is a menu item for installing and updating electronic charts.

  An example of the second menu item associated with “route monitoring” is “display setting”. The third menu item associated with the “display setting” includes, for example, “divided display” and “object setting”. “Divided display” is a menu item for displaying a plurality of charts with different scales or positions on the display unit 24. “Object setting” is a menu item for setting information to be displayed on the electronic chart.

  Examples of the fourth menu item associated with “object setting” include “display target selection” and “symbol setting”. “Selection of display target” is a menu item for selecting a target (a mark and a buoy set by the user) to be displayed on the chart. “Mark setting” is a menu item for setting the shape and the like of a mark to be displayed.

  Next, the configuration of the display unit 24 after the application is switched from ECDIS to RADAR will be described. In the present embodiment, when the application to be executed is changed, the first menu item and the second menu item are changed to menu items corresponding to the changed application (see FIG. 5). As shown in FIG. 5, even when the application is switched from ECDIS to RADAR, the first menu item display unit 31 remains arranged along the upper end of the screen, and the second menu item display unit 32 is also displayed on the screen. It is still arranged along the left edge of. Note that the number of menu items displayed on the first menu item display unit 31, the size of the menu items displayed on the second menu item display unit 32, and the like are small but change. In the present invention, it is assumed that “the display position of the menu item is substantially common” including the case where such a minute change occurs between applications.

  When the application to be displayed is switched to RADAR, the display content of the common menu item display unit 35 does not change as described above. Further, the display content of the voyage data display unit 36 changes in part so that information corresponding to the application (information about target tracking in the case of RADAR) is displayed. As the first menu item, a menu item for performing settings related to the antenna unit 10 and the radar image is displayed. Specifically, a menu item for instructing the start of transmission of a pulse signal, a menu item for selecting an antenna to be used when a plurality of radar antennas are arranged, and a menu for switching the display mode of the radar image Items can be listed.

  The radar image display mode will be described below. There are various setting items for the radar, but these settings can be performed collectively by setting the display mode. In the present embodiment, for example, a short-distance mode, a long-distance mode, a coast mode, a user setting mode (a display mode in which a user makes a desired setting), and the like are set as display modes (in the figure, MODE1, MODE2 ...).

  The first menu item display unit 31 displays the currently set display mode, as shown in FIG. When the user desires to switch the display mode, the user operates the trackball 52 and clicks the display mode of the first menu item display unit 31. Then, as shown in FIG. 6A, a list of display modes (display mode selection menu 31a) is displayed. The user can switch the display mode by clicking a desired display mode. FIG. 6 shows a state when the display mode is switched from MODE3 to MODE2.

  On the other hand, the second menu item display unit 32 displays setting items related to the radar as the second menu item. Further, the second menu item is configured to display not only the content of the setting item but also the current setting (which level is selected, whether the function is ON or OFF). Specific examples of the second menu item include pulse width setting, gain setting, and tuning setting.

  These second menu items can be collectively changed by selecting the display mode as described above (see FIG. 6). For example, when the short distance mode is selected, the respective settings are changed at the same time so that a short distance target can be easily seen.

  In addition, after switching the display mode, the user can adjust the radar image by changing the level of the setting item by the same operation as the method of selecting the third menu item when the application to be displayed is ECDIS. (See FIG. 7). In particular, in the present embodiment, the second menu item continues to be displayed and the current setting is displayed in the second menu item, so this adjustment can be easily performed.

  As described above, the menu item is selected using the operation knob 51 and the trackball 52 in the same procedure (selection method) as in the case where the application is ECDIS. When the application is RADAR, unlike the case of ECDIS, it is necessary to select from the pull-down display mode selection menu 31a when selecting the first menu item. In the present invention, it is assumed that “the method for selecting menu items is substantially common” including the case where the selection method is slightly different between applications.

  As described above, in the information display device 20 of the present embodiment, the information image created by executing the selected application is displayed, and the name of the selected application is displayed in the upper left corner of the screen. The first menu item is displayed in the left-right direction along the edge of the screen from the place where the application name is displayed. In the information display device 20, the second menu item associated with the first menu item is displayed in the vertical direction along the edge of the screen from the place where the application name is displayed. In the information display device 20, when an application to be executed is changed, a menu item corresponding to the changed application is displayed. In addition, the process regarding the display of the display part 24 shown above is performed by running the program memorize | stored in the said ROM of the control part 21, as mentioned above.

  Thereby, a feeling of operation can be unified among a plurality of applications. Further, even in an application having a large number of menu items (for example, ECDIS), a desired menu item can be easily found.

  In addition, the information display device 20 of the present embodiment continues to display the second menu item even after processing is performed based on the selection of the second menu item. Therefore, when the second menu item associated with the first menu item is continuously selected, the second menu item can be selected with a simple operation.

  In addition, since an identification mark for identifying the second menu item associated with the third menu item is displayed on the information display device 20, the user can easily view the third menu item by looking at the second menu item. The presence or absence of menu items can be grasped. Further, since the third menu item is displayed only when the second menu item is selected, it is possible to prevent the visibility of the screen from being lowered by the third menu item.

  In addition, the information display device 20 of this embodiment includes a selection operation unit (operation knob 51 and trackball 52). The selection operation unit can select at least one of the first menu item and the second menu item. Therefore, even in the present configuration in which the positions of the first menu item and the second menu item tend to be separated from each other, it is possible to prevent the time and labor required for selecting the menu item from increasing.

  Moreover, the information display apparatus of this embodiment has the following characteristics and effects. In other words, in the information display device, the menu items used in the selected application include the first menu item and the second menu item. The first menu item is displayed in the vertical direction or the horizontal direction along the edge of the screen. The second menu item is a menu item displayed in the vertical direction or the horizontal direction along the edge of the screen and associated with the first menu item.

  As a result, the visibility of the information image at the time of selection of the menu item can be compared with the pull-down menu structure in which the menu item is displayed below the selection item by selecting the item arranged side by side at the top of the screen. Can be improved.

  In the information display device, the arrangement direction is different between the first menu item and the second menu item.

  Thereby, the first menu item and the second menu item can be arranged in an L shape, and the menu items can be brought close to each other. Therefore, the user can grasp the contents of both menu items without moving the line of sight much. In addition, since the positions of the menu items can be collected, the operability for the user can be improved.

  In the information display device, the display unit displays a menu item for selecting an application at a position where the arrangement direction of the first menu item and the arrangement direction of the second menu item intersect.

  Thereby, the display position of the menu item for selecting an application can be brought close to the display positions of the first menu item and the second menu item. Accordingly, the positions of the menu items can be further gathered, so that the user operability can be further improved.

  In the information display device, the display unit displays a menu item for selecting an application in any one of the upper left, upper right, lower left, and lower right corners of the display screen.

  Thereby, since the display screen can be effectively used, an information image created by executing the application can be displayed in a large size.
