Description

  The present invention relates to a display device having display means for displaying a switch operated by an operation device, and an operation display system having the display device.

  As a display device provided with display means (liquid crystal display or the like) for displaying a switch operated by the operation device, for example, there is an in-vehicle display device for operating a navigation device, an audio, an air conditioner, or the like. As an operation method of the display switch in this in-vehicle display device, there are known a touch panel type method in which the screen of the display unit is touched as it is and a method of remote operation by a remote operation device mounted at a position away from the display unit. .

  When the former touch panel method is adopted, the display means must be mounted at a position where the driver can easily touch with a finger, and the position of the display means becomes relatively low. However, there is a problem that it takes a long time to take a look away from the road surface. In addition, the restriction of the display means mounting position also becomes a restriction on the interior design. Therefore, in recent years, the latter remote operation method is often employed.

  As a remote operation device, for example, there are devices equipped with up / down / left / right keys and a rotary commander. The former remote control device has an up / down / left / right key and a confirmation key, and a selection instruction means (cursor etc.) for selecting a display switch to be operated is moved by the up / down / left / right key to select a desired switch. The function corresponding to the selected switch is executed by operating the confirmation key in the state. Similarly, the latter remote operation device is also provided with a rotary commander and a confirmation key, and the selection instruction means is moved by rotating the rotary commander, and the confirmation key is operated with a desired switch selected. As a display device in which the operation of the display switch is performed by this rotary commander, for example, there is a device described in Patent Document 1.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating an example of an appearance inside a vehicle on which the operation display system 100 according to the present embodiment is mounted, and FIG. 2 is a functional block diagram illustrating an example of a functional configuration of the operation display system 100. As shown in FIGS. 1 and 2, the operation display system 100 includes a display device 10 and an operation device 20. The display device 10 and the operation device 20 are connected by a bus 30 so that data communication is possible.

The display device 10 is installed inside the dashboard 3 in the vehicle.
The display device 10 is connected to a navigation device, an audio device, an air conditioner device or the like as an operation target device, and is controlled by the control unit 11 based on an input signal from the operation device 20 via various source processing units 12. Predetermined functions (a navigation function that performs guidance according to a route search result, an audio function that outputs video and sound, an air conditioner function that adjusts the temperature inside the vehicle, and the like) are executed on the operation target device.

  In this example, the display unit 13 included in the display device 10 is disposed on the dashboard 3 next to the steering wheel 2 as an easily visible position in the vehicle. The display unit 13 displays a menu (see FIG. 6 and the like) including at least one switch for causing the operation target device to execute a predetermined function under the control of the control unit 11. The user operates the switch displayed on the display unit 13 using the operation device 20 while referring to the display on the display unit 13 to cause the operation target device to execute a predetermined function.

  The display device 10 includes a storage unit 14. The storage unit 14 stores a switch data management table set for each menu displayed on the display unit 13 in an updatable manner. The switch data management table will be described later.

  The operation device 20 is disposed at a position apart from the display device 10, in this example, beside the driver seat 1 in the vehicle. The operation device 20 includes a stick 21 (corresponding to an operation member) that is movable by a user, and an execution key 22. The user selects a switch to be operated on the display unit 13 using the stick 21 and presses the execution key 22 in the selected state to execute the function of the selected switch. The operation device 20 includes a microcomputer 23. The microcomputer 23 detects an operation state of the stick 21, that is, coordinate data representing a movable position, by processing an input signal (variable resistance value or the like) from the stick 21 (hysteresis processing or the like). Then, the detected coordinate data is output to the display device 10 via the bus 30. The microcomputer 23 (corresponding to coordinate data supply means) outputs (supplies) the operation signal to the display device 10 via the bus 30 when the user presses the execution key 22.

  In the example shown in FIG. 1, the stick 21 and the execution key 22 of the operation device 20 are separate members. However, for example, when the stick 21 is depressed, the stick 21 functions as an execution key. May be. In addition, the position of the execution key 22 in the case of using a separate member is not limited to the rear side of the stick 21 shown in FIG. .

  FIG. 3 is a diagram conceptually illustrating the movable mechanism of the stick 21 in the operation device 20, and FIG. 4 is a diagram illustrating a coordinate system representing the movable position of the stick 21.

  As shown in FIG. 3, the stick 21 includes an operation knob 21a that is operated by a user, a shaft 21b, a ball joint 21c that rotatably supports the shaft 21b in an arbitrary direction, a spring 21d, and a ball bearing 21e. And. Below the stick 21, a curved plate 24 having a curved surface shape corresponding to the movement locus of the ball bearing 21e due to the rotation operation about the ball joint 21c of the stick 21 is provided. The ball bearing 21e of the stick 21 is biased toward the curved plate 24 by a spring 21d and rolls on the curved plate 24. The ball bearing 21e can be moved up and down in the axial direction of the shaft 21b by a guide member (not shown).

  The curved plate 24 is provided with a plurality of (in this example, 7 × 6 = 42) concave portions 25 at predetermined positions. As a result, the stick 21 can obtain an operation reaction force (click feeling) at each position where the ball bearing 21e is fitted in the concave portion 25 of the curved plate 24, and the user can apply the operation reaction force by the operation reaction force. Can be stopped naturally at the predetermined position. The stop position of the stick 21 is detected by detection means (not shown), and is output to the microcomputer 23 as a position signal such as a variable resistance value as described above.

  The microcomputer 23 detects coordinate data representing the movable position of the stick 21 based on the input signal from the stick 21, and outputs (supplies) the detected coordinate data to the display device 10 via the bus 30. As shown in FIG. 4, the coordinate system representing the movable position of the stick 21 is a two-dimensional coordinate composed of an X-axis direction corresponding to the horizontal direction on the display unit 13 and a Y-axis direction corresponding to the vertical direction on the display unit 13. It is a system. In the example shown in FIG. 4, corresponding to FIG. 3, the coordinate data representing the movable position of the stick 21 is composed of 42 arrays X1Y1 to X7Y6. As shown in FIGS. 3 and 4, the positional relationship between the concave portions 25 on the curved plate 24 is opposite to the positional relationship between the coordinate data detected by the microcomputer 23 (the center of the coordinate system is rotated). The positional relationship is rotated 180 degrees as the center. That is, when the stick 21 is at the position shown in FIG. 3, the coordinate data representing the movable position of the stick 21 is X2Y3 (indicated by the oblique lines in FIG. 4). As a result, the operation direction of the operation knob 21a and the movement direction of the coordinate data substantially match, and the user can perform the operation without a sense of incongruity.

  Although not shown in FIG. 3, as shown in FIG. 5, grooves 26 are respectively formed between the concave portions 25 in the curved plate 24. As a result, the ball bearing 21e is guided from the recess 25 to the adjacent eight recesses 25 (upper, lower, left, right and upper right, lower right, upper left, lower left recesses 25), and the user can 21 can be naturally operated in eight directions (upward, downward, leftward, rightward and upper rightward, lower rightward, upper leftward, leftward) shown in FIG.

  Note that the arrangement of coordinate data representing the movable position of the stick 21 (that is, the arrangement of the recesses 25 formed in the curved plate 24) is determined in advance according to the number of switches included in the menu displayed on the display unit 13. Specifically, the number of coordinate data in the X coordinate direction is similarly set to the Y coordinate so that the number of switches in the menu in which the number of horizontal switches is the maximum among the plurality of menus displayed on the display unit 13. The coordinate data arrangement is determined so that the number of coordinate data in the direction is the number of switches in the menu having the maximum number of switches in the vertical direction among the menus displayed on the display unit 13. Hereinafter, a case where the coordinate data representing the movable position of the stick 21 is 42 arrays from X1Y1 to X7Y6 as in the above-described FIGS. 3 and 4 will be described as an example.

  FIG. 6 is a diagram illustrating an example of a menu displayed on the display unit 13.

  In the example shown in FIG. 6, the display unit 13 displays a menu for playing music on the audio device. Each of the switches SW1 to SW7 is associated with a source item menu corresponding to each music source. In the example shown in FIG. 6, the switch SW3 corresponding to the FM radio is selected from the switches SW1 to SW7, so that the FM radio is reproduced from the audio device under the control of various source processing units 12. A source item menu related to FM radio is displayed below the switch SW3. This FM radio source item menu includes switches SW8 to SW13 and SW15 to SW17. SW14 is a switch for displaying “Main Menu” for calling a menu other than music playback such as a navigation or an air conditioner, and SW18 is a switch for displaying a menu related to sound. Each switch is associated with switch function data, and is stored as a switch function data table (not shown) in an appropriate storage means (such as the storage unit 14).

  The switches SW1 to SW7, SW14, and SW18 are associated with different menus that are changed by menu changes. Data relating to this menu change is included in the switch function data. Therefore, when the data regarding the menu change corresponding to the switch executed by the user is included, the control unit 11 displays the designated other menu.

  FIG. 7 shows an example of a switch data management table corresponding to the menu shown in FIG.

  The switch data management table is preset for each menu displayed on the display unit 13 and stored in the storage unit 14. This switch data management table has a data structure in which each switch included in the menu is assigned to coordinate data (see FIG. 4) arranged in a predetermined array corresponding to the movable range of the stick 21. For this reason, in the switch data management table, all the switches included in the corresponding menu are assigned to any coordinate data. Note that the switch assignment to the coordinate data in the switch data management table includes the coordinate data input from the operation device 20 under the control of the control unit 11 and the switch layout configuration (size, number of columns, number of rows, etc.) in the menu. ) Is corrected based on at least one of the following. The correction of the switch assignment will be described in detail later.

  As shown in FIG. 7, SW1 to SW18 are assigned to coordinate data composed of 42 arrays X1Y1 to X7Y6 so as to correspond to the switch arrangement in the menu shown in FIG. 6. In this example, SW1 to SW18 are assigned from the smaller X coordinate and Y coordinate (that is, so as to be aligned at the upper left of the table). As a result, the switch data management table includes coordinate data to which any switch is assigned (hereinafter referred to as “valid coordinate data”) and coordinate data to which no switch is assigned (hereinafter referred to as “invalid coordinate data”). (Indicated as “-” in the figure).

  Each valid coordinate data record in the switch data management table stores the switch data of the assigned switch. FIG. 8 shows an example of switch data of the switch SW1 stored in the record of the coordinate data X1Y1. As shown in FIG. 8, the switch data is composed of display coordinate data representing the display position of the switch on the screen of the display unit 13, display size data representing the display size, and destination data. . When the stick 21 is operated when the movable position of the stick 21 corresponds to the coordinate data, the movement destination data is a switch data management table with respect to the operation direction (in this example, four directions, up, down, left, and right). This is information that defines which record the upper record is moved to. In the example shown in FIG. 8, when the movable position of the stick 21 corresponds to the coordinate data X1Y1, and the stick 21 is operated downward, the record is moved to the coordinate data X1Y2 (the switch SW8 is assigned). When the stick 21 is operated in the right direction, the record is moved to the coordinate data X2Y1 (the switch SW2 is assigned). In addition, when the movable position of the stick 21 corresponds to the coordinate data X1Y1, the stick 21 cannot be operated further upward and leftward. Therefore, it is not necessary to define the movement destination in the upward and leftward directions. The coordinate data X1Y1 may be defined as fail-safe.

  Next, a cursor display process when a new menu is displayed on the display unit 13 will be described. Note that the new menu refers to, for example, a menu that is displayed first after the power is turned on or a menu that is newly displayed by switching the menu.

  In the present embodiment, the display unit 13 displays a cursor C (corresponding to a selection instruction unit) for selecting a switch desired by the user so as to overlap the menu. The user can select the switch from the menu by moving the stick 21 of the operation device 20 and moving the cursor C displayed on the display unit 13 to a desired switch position. Then, in a state where the switch is selected, when the user operates the execution key 22 provided in the operation device 20, a function corresponding to the selected switch is executed.

  In the following description, the cursor C is displayed as a selection instruction means for selecting a switch. However, the present invention is not limited to this. For example, the display mode of the selected switch may be changed (color / size). The display of the selection instruction means may be performed by displaying text related to the function of the selected switch or the like.

  When a new menu is displayed on the display unit 13 and the movable position of the stick 21 of the operation device 20 corresponds to the effective coordinate data to which the switch is assigned, the assignment content of the switch in the switch data management table is not corrected. The cursor C is displayed on the switch assigned to the effective coordinate data.

  FIG. 9 is a diagram illustrating an example of the movable position of the stick 21 in this case, and FIG. 10 is a diagram illustrating an example of the display position of the cursor C in this case. As shown in FIG. 9, when a new menu is displayed on the display unit 13, for example, when the stick 21 of the operation device 20 exists at a movable position corresponding to the coordinate data X4Y1, as shown in FIG. 7 described above. Since the coordinate data X4Y1 is valid coordinate data to which the switch SW4 is assigned, the control unit 11 acquires the switch data of the switch SW4 stored in the record of the coordinate data X4Y1 in the switch data management table. Based on the display coordinate data of the switch SW4 included in the switch data, the cursor C is displayed at the position of the switch SW4. Thereby, as shown in FIG. 10, when a new menu is displayed, the cursor C is displayed on the switch SW4, and the switch SW4 is selected. If the user operates the execution key 22 in this state, a source item menu related to the AM radio corresponding to the switch SW4 is displayed below the switch SW4 (not shown).

  On the other hand, when a new menu is displayed on the display unit 13, if the movable position of the stick 21 corresponds to invalid coordinate data to which no switch is assigned, one of the switches is disabled by the control of the control unit 11. The assignment contents of the switch are corrected so as to be assigned to the coordinate data.

  FIG. 11 is a diagram illustrating an example of the movable position of the stick 21 in this case, FIG. 12 is a diagram illustrating an example of correction of switch assignment contents performed in this case, and FIG. It is a figure showing an example of the display position of cursor C.

  As shown in FIG. 11, when a new menu is displayed on the display unit 13, for example, when the movable position of the stick 21 of the operation device 20 corresponds to the coordinate data X4Y3, as shown in FIG. 12, the coordinate data X4Y3 is displayed. Since the invalid coordinate data has no switch assignment, the switch assignment is corrected so that any switch is assigned to the invalid coordinate data. Specifically, the coordinate data X1Y3 having the same Y coordinate as the invalid coordinate data X4Y3 and the smallest X coordinate is searched, and it is determined whether or not a switch is assigned to the coordinate data. When a switch is assigned (that is, when it is valid coordinate data), the valid coordinate data having the maximum X coordinate is further searched, and the switch corresponding to the valid coordinate data is assigned to invalid coordinate data. In this example, since the coordinate data X1Y3 is valid coordinate data, the valid coordinate data having the maximum X coordinate, that is, the switch SW11 corresponding to the coordinate data X2Y3 is assigned to the invalid coordinate data X4Y3. Thereby, the control unit 11 acquires the switch data of the switch SW11 stored in the record of the coordinate data X2Y3, and displays the cursor C based on the display coordinate data of the switch SW11 included in the switch data. Accordingly, as shown in FIG. 13, when a new menu is displayed, the cursor C is displayed on the switch SW11, and the switch SW11 is selected.

  Note that when the user operates the execution key 22 in this state, the control unit 11 reads the switch function data corresponding to the switch SW11 from the switch function data table of the storage unit described above, and assigns functions related to the data to the various source processing units 12. The audio device is executed under the control of As a result, the FM radio corresponding to the FM5 channel is reproduced.

  On the other hand, when the movable position of the stick 21 corresponds to the invalid coordinate data as described above, the switch is not assigned to the coordinate data in which the Y coordinate is the same and the X coordinate is the smallest (that is, the invalid coordinate data is invalid). In the case of coordinate data), the control unit 11 increases or decreases (decreases in this example) the Y coordinate of the invalid coordinate data, which is the movable position of the stick 21, and the effective coordinate whose X coordinate is the same as the invalid coordinate data. The data is searched, and the switch assignment is corrected so that the switch corresponding to the valid coordinate data is assigned to the invalid coordinate data.

  FIG. 14 is a diagram illustrating an example of the movable position of the stick 21 in this case, FIG. 15 is a diagram illustrating an example of correction of the switch assignment content performed in this case, and FIG. It is a figure showing an example of the display position of cursor C.

  As shown in FIG. 14, when a new menu is displayed on the display unit 13, for example, when the movable position of the stick 21 of the operation device 20 corresponds to the coordinate data X3Y6, as shown in FIG. 15, the coordinate data X3Y6 is displayed. Is invalid coordinate data to which no switch is assigned, and no switch is assigned to the coordinate data X1Y6 that has the same Y coordinate as the invalid coordinate data X3Y6 and the minimum X coordinate (that is, invalid coordinate data). ). Therefore, the control unit 11 searches the coordinate data X3Y5 obtained by reducing the Y coordinate of the invalid coordinate data X3Y6 that is the movable position of the stick 21, and determines whether or not a switch is assigned to the coordinate data. When a switch is assigned (that is, when it is valid coordinate data), a switch corresponding to the valid coordinate data is assigned to the invalid coordinate data. In this example, since the coordinate data X3Y5 is valid coordinate data, the switch SW16 corresponding to the valid coordinate data X3Y5 is assigned to the invalid coordinate data X3Y6. Thereby, the control unit 11 acquires the switch data of the switch SW16 stored in the record of the coordinate data X3Y5, and displays the cursor C based on the display coordinate data of the switch SW16 included in the switch data. Thus, as shown in FIG. 16, when a new menu is displayed, the cursor C is displayed on the switch SW16, and the switch SW16 is selected.

  When the user operates the execution key 22 in this state, the control unit 11 reads the data related to the menu change corresponding to the switch SW16 from the switch function data table of the storage unit described above, and displays the menu specified as the transition destination. Execute.

  On the other hand, when the movable position of the stick 21 corresponds to invalid coordinate data as described above, no switch is assigned to coordinate data having the same Y coordinate and the minimum X coordinate as the invalid coordinate data, and When the switch is not assigned to the coordinate data obtained by reducing the Y coordinate of the invalid coordinate data that is the movable position of the stick 21 (that is, the invalid coordinate data), the reduced Y coordinate is the same as described above. Process. That is, the control unit 11 determines whether or not a switch is assigned to the coordinate data that minimizes the X coordinate in the reduced Y coordinate, and when the switch is assigned (that is, effective coordinate data). In the case), the effective coordinate data having the maximum X coordinate is further searched, and the switch corresponding to the effective coordinate data is assigned to the invalid coordinate data.

  FIG. 17 is a diagram illustrating an example of the movable position of the stick 21 in this case, FIG. 18 is a diagram illustrating an example of correction of the switch assignment content performed in this case, and FIG. It is a figure showing an example of the display position of cursor C.

  As shown in FIG. 17, when a new menu is displayed on the display unit 13, for example, when the movable position of the stick 21 of the operation device 20 corresponds to the coordinate data X7Y6, as shown in FIG. 18, the coordinate data X7Y6 is displayed. Is invalid coordinate data to which no switch is assigned, and no switch is assigned to the coordinate data X1Y6 that has the same Y coordinate as the invalid coordinate data X7Y6 and the minimum X coordinate (that is, invalid coordinate data). ). Therefore, the coordinate data X7Y5 obtained by reducing the Y coordinate of the invalid coordinate data X7Y6 that is the movable position of the stick 21 is searched, and it is determined whether or not a switch is assigned to the coordinate data.

  In this example, since the switch is not assigned to the coordinate data X7Y5 in which the Y coordinate is reduced (that is, the invalid coordinate data), in the reduced Y coordinate, the switch is set to the coordinate data X1Y5 that minimizes the X coordinate. It is determined whether or not it is assigned. Since the coordinate data X1Y5 is valid coordinate data, the valid coordinate data having the maximum X coordinate, that is, the switch SW18 corresponding to the coordinate data X5Y5 is assigned to the invalid coordinate data X7Y6. Thereby, the control unit 11 acquires the switch data of the switch SW18 stored in the record of the coordinate data X5Y5, and displays the cursor C based on the display coordinate data of the switch SW18 included in the switch data. Thus, as shown in FIG. 19, when a new menu is displayed, the cursor C is displayed on the switch SW18, and the switch SW18 is selected.

  When the user operates the execution key 22 in this state, the control unit 11 reads the data relating to the menu change corresponding to the switch SW18 from the switch function data table of the storage unit described above, and executes the menu display related to the sound. .

  Next, an operation process of the cursor C in the display unit 13 when the user operates the stick 21 of the operation device 20 will be described.

  First, detection of whether or not the user has operated the stick 21 will be described. The control unit 11 sequentially acquires coordinate data representing the movable position of the stick 21 output from the operation device 20 at predetermined time intervals (for example, 0.1 second) while the display device 10 is powered on. To do. At this time, the control unit 11 first saves the coordinate data acquired first after power-on in the storage unit 14 (corresponding to the storage unit), and then acquires the current coordinate data (second coordinate data acquired) at predetermined time intervals. Equivalent) and the coordinate data (corresponding to the first coordinate data) stored in the storage unit 14 to determine whether or not the stick 21 is operated. If there is a difference between the coordinate data, it is considered that the stick 21 has been operated, and the coordinate data stored in the storage unit 14 is updated to new coordinate data. In this way, the control unit 11 constantly monitors whether or not the user has operated the stick 21 by comparing the coordinate data stored in the storage unit 14 with the current coordinate data acquired from the operation device 20. Further, the control unit 11 detects the relative displacement of the movable position of the stick 21 (how many coordinates are moved in which direction) by comparing the coordinate data.

  Hereinafter, specific examples of the operation of the cursor C will be sequentially described. 20 is a diagram illustrating an example of the movable operation of the stick 21, and FIG. 21 is a diagram illustrating an example of the switch data related to the switch SW9 stored in the record of the coordinate data X2Y2 of the switch data management table. 22 is a diagram illustrating an example of the operation of the cursor C when the stick operation illustrated in FIG. 20 is performed.

  As shown in FIG. 20, when the stick 21 is operated from the coordinate data X2Y2 to X2Y3, the control unit 11 compares the current coordinate data X2Y3 acquired from the operation device 20 with the coordinate data X2Y2 stored in the storage unit 14. By doing so, it is detected that the stick 21 has been operated downward by one coordinate. At this time, the control unit 11 acquires the switch data related to the switch SW9 stored in the record of the coordinate data X2Y2 before the operation, and refers to the movement destination data corresponding to the downward direction included in the switch data. As shown in FIG. 21, in this example, since the movement destination record is coordinate data X2Y3 (switch SW11), the coordinate data X2Y3 is determined as the movement destination record. Then, the switch data related to SW11 stored in the movement destination record is acquired, and the cursor C is displayed at the position of the switch SW11 based on the display coordinate data of the switch SW11 included in the switch data. At this time, the display of the cursor C at the position of the switch SW9 before the stick operation is stopped. As a result, as shown in FIG. 22, the display position of the cursor C is changed (moved) from the switch SW9 to the switch SW11, and the switch SW11 is selected.

  The cursor C at this time may be moved instantaneously from the switch SW9 to the switch SW11 in accordance with the operation of the stick 21, or may be moved slowly at a predetermined speed. Also good.

  FIG. 23 is a diagram illustrating another example of the movable operation of the stick 21, and FIG. 24 is a diagram illustrating an example of switch data of the switch SW11 stored in the record of the coordinate data X2Y3 of the switch data management table. FIG. 25 is a diagram illustrating an example of the operation of the cursor C when the stick operation illustrated in FIG. 23 is performed.

  As shown in FIG. 23, when the stick 21 is operated from the coordinate data X2Y2 to X1Y3, the control unit 11 uses the current coordinate data X1Y3 acquired from the operation device 20 and the coordinates stored in the storage unit 14 as described above. By comparing with the data X2Y2, it is detected that the stick 21 has been operated by two coordinates in the diagonally downward direction (one for the X coordinate direction and one for the Y coordinate direction). In this embodiment, when the stick 21 is operated in an oblique direction as described above, the movement of the stick 21 is decomposed into the X coordinate direction and the Y coordinate direction and processed. In other words, in this example, the process is executed assuming that one coordinate is moved downward from the coordinate data X2Y2 and then one coordinate is moved leftward from the coordinate data X2Y3. Therefore, first, switch data related to the switch SW9 stored in the record of the coordinate data X2Y2 of the stick 21 before operation is acquired, and the movement destination data corresponding to the downward direction included in the switch data is referred to. As shown in FIG. 21 described above, in this example, the destination record is coordinate data X2Y3 (switch SW11). Next, the switch data related to the switch SW11 stored in the record of the coordinate data X2Y3 is acquired, and the destination data corresponding to the left direction included in the switch data is referred to. As shown in FIG. 24, in this example, the destination record is coordinate data X1Y3 (switch SW10). Therefore, the coordinate data X1Y3 is determined as the movement destination record. Then, the switch data related to the SW 10 stored in the movement destination record is acquired, and the cursor C is displayed based on the display coordinate data of the switch SW 10 included in the switch data. At this time, the display of the cursor C at the position of the switch SW9 before the stick operation is stopped. As a result, as shown in FIG. 25, the display position of the cursor C is changed from the switch SW9 to the switch SW10, and the switch SW10 is selected.

  When the stick 21 is operated in an oblique direction in this way, the cursor C is not displayed at a position corresponding to the coordinate data X2Y3 (switch SW11), which is halfway, and the cursor C moves from the switch SW9 to the switch SW10. Appear to move directly to.

  FIG. 26 is a diagram illustrating another example of the movable operation of the stick 21, and FIG. 27 is a diagram illustrating an example of the operation of the cursor C when the stick operation illustrated in FIG. 26 is performed.

  As shown in FIG. 26, when the stick 21 is operated from the coordinate data X2Y2 to X1Y5, as described above, the control unit 11 uses the current coordinate data X1Y5 acquired from the operation device 20 and the coordinates stored in the storage unit 14. By comparing with the data X2Y2, it is detected that the stick 21 has been operated in an obliquely downward direction for four coordinates (one for the X coordinate direction and three for the Y coordinate direction). Also in this case, as described above, first, the coordinate data X2Y2 is moved downward by three coordinates, and then the processing is executed assuming that the coordinate data X2Y5 is moved leftward by one coordinate. The description of the switch data that passes halfway is omitted, but in this example, the coordinate data X1Y5 is finally determined as the destination record. Then, the switch data related to the SW 14 stored in the movement destination record is acquired, and the cursor C is displayed based on the display coordinate data of the switch SW 14 included in the switch data. At this time, the display of the cursor C at the position of the switch SW9 before the stick operation is stopped. Thereby, as shown in FIG. 27, the display position of the cursor C is changed from the switch SW9 to the switch SW14, and the switch SW14 is selected. In this case as well, the intermediate progress is not displayed as described above, and the cursor C is displayed so as to move directly from the switch SW9 to the switch SW14.

  In the above description, the switch is present in the menu in the direction of operation of the stick 21. However, for example, the switch at the menu end is selected and the operation member is further operated in the direction of the end. Next, the operation of the cursor C when there is no switch in the operation direction destination of the stick 21 will be described. In this case, the stick 21 is operated from the position corresponding to the effective coordinate data to the position corresponding to the invalid coordinate data adjacent to the effective coordinate data. In this case, the control unit 11 controls the operation before the operation. The switch assignment is corrected so that the switch corresponding to the valid coordinate data is assigned to the invalid coordinate data after the operation.

  FIG. 28 is a diagram illustrating an example of a movable operation of the stick 21 in this case, FIG. 29 is a diagram illustrating an example of correction of switch assignment contents performed in this case, and FIG. 30 is a diagram illustrating FIG. It is a figure showing an example of operation | movement of the cursor C when the stick operation shown is performed.

  As shown in FIG. 28, when the stick 21 is operated from X2Y2 that is valid coordinate data to X3Y2 that is invalid coordinate data, the control unit 11 determines that the current coordinate data X3Y2 acquired from the operation device 20 and By comparing the coordinate data X2Y2 stored in the storage unit 14, it is detected that the stick 21 has been operated by one coordinate in the right direction. Then, switch data related to the switch SW9 stored in the record of the coordinate data X2Y2 before the operation is acquired, and the destination data corresponding to the right direction included in the switch data is referred to. At this time, as shown in FIG. 21, the movement destination record corresponding to the right direction is the same coordinate data X2Y2 (switch SW9) as before the operation, so the coordinate data X2Y2 is determined as the movement destination record (ie, Do not move records). That is, the switch SW9 corresponding to the coordinate data X2Y2 is assigned to the invalid coordinate data X3Y2. Then, the switch data related to SW9 stored in the coordinate data X2Y2 is acquired, and the cursor C is displayed at the position of the switch SW9 based on the display coordinate data of the switch SW9 included in the switch data. As a result, as shown in FIG. 30, the cursor C does not move from the switch SW11 and is continuously displayed on the switch SW11.

  FIG. 31 is a diagram showing an example in which the stick 21 is operated from the state shown in FIG. 28 to the end of the movable range in the same direction, and FIG. 32 is an example of correction of switch assignment performed in this case. FIG. 33 is a diagram illustrating an example of the operation of the cursor C when the stick operation illustrated in FIG. 31 is performed.

  As shown in FIG. 31, when the stick 21 is operated from the coordinate data X3Y2 toward the coordinate data X7Y2 (may be operated one by one for each coordinate or may be operated at a stroke), the control unit 11 It is detected that the stick 21 has been operated by four coordinates in the right direction. Then, switch data relating to the switch assigned to the coordinate data X3Y2 before the operation is acquired. At this time, the switch SW9 corresponding to the coordinate data X2Y2 is assigned to the coordinate data X3Y2 by the correction described above. As a result, the control unit 11 acquires the switch data related to the switch SW9 stored in the record of the coordinate data X2Y2, and refers to the movement destination data corresponding to the right direction included in the switch data. As described above, since the movement destination record corresponding to the right direction of the movement destination data is the coordinate data X2Y2 (switch SW9), the coordinate data X2Y2 is determined as the movement destination record as described above (that is, the record) Do not move). That is, the switch SW9 corresponding to the coordinate data X2Y2 is assigned to the invalid coordinate data X4Y2. Thereafter, by repeating the same process, the switch SW9 is sequentially assigned to the invalid coordinate data X5Y2, X6Y2, and X7Y2. Thereby, the control unit 11 acquires the switch data of the switch SW9 stored in the record of the coordinate data X2Y2, and displays the cursor C based on the display coordinate data of the switch SW9 included in the switch data. As a result, as shown in FIG. 33, the cursor C does not move from the switch SW11 and is continuously displayed on the switch SW11.

  FIG. 34 is a diagram illustrating an example in which the stick 21 is operated in the opposite direction from the state illustrated in FIG. 31. FIG. 35 is a diagram illustrating an example of correction of switch assignment performed in this case. 36 is a diagram illustrating an example of the operation of the cursor C when the stick operation illustrated in FIG. 34 is performed.

  As shown in FIG. 34, when the stick 21 is operated from the coordinate data X7Y2 toward the coordinate data X6Y2, the control unit 11 detects that the stick 21 has been operated by one coordinate in the left direction. Then, switch data related to the switch assigned to the coordinate data X7Y2 before operation is acquired. At this time, the switch SW9 corresponding to the coordinate data X2Y2 is assigned to the coordinate data X7Y2 by the correction described above. As a result, the control unit 11 acquires the switch data related to the switch SW9 stored in the record of the coordinate data X2Y2, and refers to the movement destination data corresponding to the left direction included in the switch data. At this time, since the movement destination record corresponding to the left direction is the coordinate data X1Y2 (switch SW8) as shown in FIG. 21, the coordinate data X1Y2 is determined as the movement destination record. Thereby, the control unit 11 acquires the switch data of the switch SW8 stored in the record of the coordinate data X1Y2, and displays the cursor C based on the display coordinate data of the switch SW8 included in the switch data. At this time, the display of the cursor C at the position of the switch SW9 before the stick operation is stopped. As a result, as shown in FIG. 36, the display position of the cursor C is changed from the switch SW9 to the switch SW8, and the switch SW8 is selected.

  As described above, when the stick 21 is operated from the coordinate data X2Y2 to the coordinate data X7Y2 and then operated by one coordinate in the left direction, the stick 21 is moved from the position corresponding to the coordinate data X2Y2 before the operation to the left. The switch assignments are corrected so that the operation is the same as when one coordinate is operated in the direction.

  FIG. 37 is a flowchart illustrating a procedure example of display processing executed by the control unit 11 when the display operation as described above is performed by the display device 10. In this flowchart, processing is started based on control of the control unit 11 when the power of the display device 10 is turned on.

  In step S1, the control unit 11 acquires image data corresponding to the menu from an image database (not shown), outputs a display signal to the display unit 13, and displays a menu (for example, a main menu) based on the acquired image data. To do.

  In step S <b> 2, the control unit 11 acquires from the storage unit 14 a switch data management table corresponding to the menu displayed in step S <b> 1.

  In step S3, the control unit 11 performs a new cursor display process that is a process of determining the display position of the cursor C when a new menu is displayed (see FIG. 38 described later).

  In step S4, the control unit 11 determines whether or not the execution key 22 of the operation device 20 has been operated by the user based on whether or not the operation signal of the execution key 22 has been input from the operation device 20 via the bus 30. To do. When the operation signal of the execution key 22 is input (step S4: Yes), the process proceeds to step S5.

  In step S5, the control unit 11 reads the switch function data table stored in an appropriate storage unit (may be the storage unit 14), and is selected by the cursor C (displayed by the new cursor display process in step S3). Switch function data corresponding to the selected switch is acquired.

  In step S6, the control part 11 determines whether the data regarding a menu change are contained in the switch function data acquired by said step S5. If data related to the menu change is included (step S6: Yes), the process is returned to the previous step S1, and the display of the designated menu is executed. Thereafter, the same processing as described above is repeated. On the other hand, when the data regarding the menu change is not included (step S6: No), the process returns to the previous step 4.

  On the other hand, the control part 11 transfers a process to step S8, when the operation signal of the execution key 22 is not input in the said step S4 (step S4: No). In step S <b> 8, the control unit 11 acquires coordinate data representing the current movable position of the stick 21 output from the operation device 20. As described above, the control unit 11 acquires the coordinate data at predetermined time intervals (for example, 0.1 seconds).

  In step S <b> 9, the control unit 11 compares the coordinate data representing the current movable position of the stick 21 acquired in step S <b> 8 with the coordinate data stored in the storage unit 14. The storage of the coordinate data in the storage unit 14 is performed in the new cursor display process in step S3 (see step S22 in FIG. 38) or the cursor display position change process in step S11 described later (step S36 in FIG. 39). .

  In step S10, the control unit 11 determines whether or not the stick 21 has been operated based on the comparison result of the two coordinate data in step S9. If there is no difference between the two coordinate data, it is considered that the stick 21 has not been operated (step S10: No), and the process returns to the previous step S4. On the other hand, if there is a difference in the coordinate data, it is assumed that the stick 21 has been operated (step S10: Yes), and the process proceeds to step S11.

  In step S <b> 11, the control unit 11 performs a cursor display position change process for changing the display position of the cursor C based on the operation of the stick 21. Thereafter, the process returns to step 4 above.

  Although not specifically described above, the control unit 11 ends the process when an operation corresponding to the process stop is performed by the user during the process of this flowchart (when the power is turned off, etc.). To do.

  FIG. 38 is a flowchart showing the detailed contents of the new cursor display process in step S3.

  In step S <b> 21, the control unit 11 acquires coordinate data representing the current movable position of the stick 21 output from the operation device 20 via the bus 30. The acquisition of the coordinate data is also performed at predetermined time intervals (for example, 0.1 seconds) as in step S8 described above. In this flowchart, the coordinate data acquired in step S21 will be described as XnYm.

  In step S22, the control unit 11 stores the coordinate data XnYm acquired in step S21 in the storage unit 14.

  In step S23, the control unit 11 confirms a record corresponding to the coordinate data XnYm acquired in step S21 in the switch data management table acquired in step S2.

  In step S24, the control unit 11 determines whether any switch is assigned to the coordinate data XnYm in the switch data management table (that is, whether the coordinate data XnYm is valid coordinate data) or not, corresponding to the coordinate data XnYm. Judgment is made based on whether switch data is stored in the record to be recorded. If any switch is assigned to the coordinate data XnYm (step S24: Yes), the process proceeds to step S25.

  In step S25, the control unit 11 acquires switch data stored in a record corresponding to the coordinate data XnYm acquired in step S21. And a display signal is output to the display part 13, and the cursor C is displayed in the position corresponding to the display coordinate data contained in the acquired switch data. Thus, the process ends.

  On the other hand, if no switch is assigned to the coordinate data XnYm acquired in step S21 in step S24 (step S24: No), the control unit 11 proceeds to step S26.

  In step S26, the control unit 11 searches for a record of the coordinate data X1Ym in which the Y coordinate is the same as the coordinate data XnYm acquired in step S21 and the X coordinate is minimum, and any switch is assigned to the coordinate data X1Ym. Is determined (that is, whether the coordinate data X1Ym is valid coordinate data). If a switch is assigned to the coordinate data X1Ym (step S26: Yes), the process proceeds to step S27.

  In step S27, the control unit 11 searches for effective coordinate data having the maximum X coordinate among the effective coordinate data having the same Y coordinate as the coordinate data X1Ym. Then, the switch assignment is corrected so that the switch corresponding to the searched effective coordinate data is assigned to the coordinate data XnYm, and the cursor C is displayed on the assigned switch. Thus, the process ends.

  On the other hand, the control part 11 transfers a process to step S28, when the switch is not allocated to coordinate data X1Ym in the said step S26 (step S26: No).

  In step S28, the control unit 11 decreases the value m of the Y coordinate of the coordinate data XnYm by 1. Then, it returns to previous step S24 and repeats the same processing as described above. Thereby, when the switch is assigned to the coordinate data XnYm−1 obtained by reducing the Y coordinate value m by 1, the control unit 11 moves the cursor to the switch corresponding to the coordinate data XnYm−1 in step S25. C is displayed. In this case, in step S25, the switch assignment content is corrected so that the switch corresponding to the coordinate data XnYm-1 is assigned to the coordinate data XnYm acquired in step S21. On the other hand, when the switch is not assigned to the coordinate data XnYm-1, the control unit 11 assigns the switch to the coordinate data X1Ym-1 that minimizes the X coordinate in the reduced Y coordinate in step S26. If the switch is assigned, it is determined in step S27 that the effective coordinate data having the maximum X coordinate is the effective coordinate data having the same Y coordinate as that of the coordinate data X1Ym-1. A cursor C is displayed on the corresponding switch. On the other hand, if no switch is assigned to the coordinate data X1Ym-1, the value m of the Y coordinate of the coordinate data XnYm-1 is further decreased by 1 in step S28, and the process returns to step S24 again.

  FIG. 39 is a flowchart showing the detailed contents of the cursor display position changing process in step S11.

  In step S31, the control unit 11 detects the relative displacement of the stick 21 (how many coordinates are moved in which direction) based on the comparison result of the two coordinate data in step S9.

  In step S32, the control unit 11 acquires the switch data stored in the record corresponding to the coordinate data stored in the storage unit 14, and detected in the above-described step S31 among the destination data included in the switch data. The destination data corresponding to the operation direction of the stick 21 is referred to.

  In step S33, the control unit 11 determines a movement destination record in the switch data management table based on the movement destination data referred to in step S32. As a result, if the destination record does not match the coordinate data of the stick 21, the switch assignment contents are such that the switch corresponding to the destination record is assigned to the current coordinate data acquired in step S8. It has been corrected.

  In step S <b> 34, the control unit 11 determines whether or not the movement destination record determination process in steps S <b> 32 and S <b> 33 has been completed for the entire relative displacement of the stick 21. For example, when the stick 21 is operated for a plurality of coordinates as shown in FIGS. 23 and 26 described above, it is determined whether or not the movement destination record determination processing has been performed for all coordinates. If the movement destination record determination process has not been completed for the entire relative displacement (step S34: No), the process proceeds to step S32. On the other hand, when the determination process of the movement destination record has been completed for the entire relative displacement (step S34: Yes), the process proceeds to step S35.

  In step S35, the control unit 11 acquires switch data stored in the record determined in step S33. And a display signal is output to the display part 13, and the cursor C is displayed in the position corresponding to the display coordinate data contained in the acquired switch data.

  In step S36, the control unit 11 overwrites and saves the coordinate data representing the current movable position of the stick 21 acquired in step S8 in the storage unit 14, and updates the coordinate data stored in the storage unit 14. Thus, the process ends.

  In the flowcharts shown in FIGS. 37 to 39, step S8 and step S21 executed by the control unit 11 correspond to the movable position acquisition means described in the claims, and step S25, step S27 and step S35 are display control. Step S25, step S27, and step S33 correspond to assignment correction means. Step S10 corresponds to operation presence / absence detection means, and step S36 corresponds to coordinate data update means. Step S31 corresponds to a relative displacement detector.

  As described above, the display device 10 in the above-described embodiment acquires coordinate data representing the movable position of the stick 21 supplied from the operation device 20 including the stick 21 (corresponding to an operation member) that is movable by the user. And a display unit 13 (displaying a menu including at least one switch for causing the operation target device to execute a predetermined function) and a control unit 11 (in detail, step S8 and step S21, corresponding to a movable position acquisition unit). Switch data management having a data structure in which each switch included in the menu is assigned to coordinate data set for each menu and arranged in a predetermined array corresponding to the movable range of the stick 21 Acquired by the control unit 11 (specifically, step S8 and step S21) using the table A control unit 11 (specifically, step S25, step S27, and step S35 for specifying a switch assigned to the target data and displaying a cursor C (corresponding to a selection instruction unit) for selecting the switch on the display unit 13. The control unit 11 (corresponding to the display control means) and the control unit 11 (specifically, correcting the assignment contents of the switch to the coordinate data in the switch data management table based on the coordinate data acquired by the control unit 11 (specifically, step S8 and step S21). Includes step S24 to step S28 and step S33, which corresponds to an assignment correction unit.

  The operation display system 100 in the embodiment is an operation display system 100 having a display device 10 and an operation device 20 for operating a switch displayed on the display device 10, and the operation device 20 is movable by a user. The display device 10 includes a stick 21 to be operated and a microcomputer 23 (corresponding to coordinate data supply means) that supplies coordinate data representing a movable position of the stick 21 to the display device 10. A display unit 13 that displays a menu including a control unit 11 (in detail, step S8 and step S21 in detail) that acquires coordinate data supplied from the device and at least one switch for causing the operation target device to execute a predetermined function. It is set for each menu and corresponds to the movable range of the stick 21 The coordinate data arranged in a predetermined array is acquired by the control unit 11 (specifically, step S8 and step S21 in detail) using a switch data management table having a data structure in which each switch included in the menu is assigned. A control unit 11 (specifically, step S25, step S27 and step S35) for specifying a switch assigned to the coordinate data and displaying a cursor C for selecting the switch on the display unit 13, and a control unit 11 (details) The control unit 11 (in detail, step S24 to step S28, step S33) for correcting the assignment content of the switch to the coordinate data in the switch data management table based on the coordinate data acquired in step S8 and step S21). Have.

  In the display device 10 in the above embodiment, a menu including at least one switch for causing the operation target device to execute a predetermined function is displayed on the display unit 13. At this time, coordinate data representing the movable position of the stick 21 provided in the operation device 20 is acquired by the control unit 11 (specifically, step S8 and step S21). Then, the control unit 11 (specifically, step S25, step S27, and step S35) specifies the switch assigned to the acquired coordinate data using the switch data management table set for each menu, and the switch is A cursor C is displayed on the display unit 13 so as to be selected. As a result of such control, the user selects the desired switch from the menu by moving the stick 21 of the operation device 20 and moving the cursor C displayed on the display unit 13 to a desired position. be able to. Then, in the state where the switch is selected, the function of the operation target device corresponding to the selected switch is executed by operating the execution key 22 provided in the operation device 20.

  At this time, the switch data management table has a data structure in which each switch included in the menu is assigned to coordinate data arranged in a predetermined array corresponding to the movable range of the stick 21. Thus, when the movable position of the stick 21 corresponds to coordinate data to which any switch is assigned in the switch data management table, the cursor C is set so that one switch corresponding to the assignment is selected. It is displayed on the display unit 13.

  At this time, in the above-described embodiment, the control unit 11 (specifically, step S24 to step S28, step S33) corrects the switch assignment contents for the coordinate data in the switch data management table according to the movable position of the stick 21. To do. Thereby, even when the movable position of the stick 21 corresponds to invalid coordinate data to which no switch is assigned in the switch data management table, the assignment contents of the switch are corrected and appropriate to the invalid coordinate data. By assigning the switch, the user can select the switch on the display unit 13 without a sense of incongruity. As described above, by appropriately correcting the assignment contents of the switch to the coordinate data, the user can select the switch according to the movable position of the stick 21 without a sense of incompatibility regardless of the movable position of the stick 21.

  As a result, the coordinates of the operation device 20 are determined in accordance with the movable position of the stick 21 from the coordinates of a predetermined arrangement predetermined in the two-dimensional coordinate system (XY coordinate system) as in the above embodiment. Can be a simple mechanical device. Specifically, the stick 21 is moved within a movable range by a rotation operation around the ball joint 21c, and an operation reaction force (click feeling) is obtained at each position corresponding to the predetermined array coordinates. It can be set as such a structure. When the user moves the stick 21 to a desired movable position using such an operation device 20, the coordinates corresponding to the movable position are controlled by the control unit 11 (specifically, step S25, step S27 and step S35). A cursor C is displayed on the display unit 13 so as to select the switch assigned to the data.

  As a result of using such an operation device 20, the user can continuously operate the stick 21 in an arbitrary direction by a plurality of coordinates, so that the display unit 13 is far from the currently selected switch. Even when the arranged switch is selected, it can be performed by one operation. Further, if the vertical and horizontal directions in the menu coincide with the vertical and horizontal directions in the coordinate system representing the movable position of the stick 21, the user only has to operate the stick 21 in the direction toward the target switch, so that the user is rough and intuitive. The operation can be performed. Therefore, operability can be improved.

  Further, since the switch data management table associates the coordinate data of the two-dimensional coordinate system representing the movable position of the stick 21 with the switch arranged on the menu, there are restrictions due to operational characteristics as in the case of using a rotary commander. The switch can be freely arranged on the screen of the display unit 13 without receiving it. Thereby, the freedom degree of a screen design can be enlarged. As a result, it can be used in combination with a touch panel system.

  In addition, as a result of using a simple mechanical operation device such as the operation device 20, information supplied from the operation device 20 to the display device 10 includes coordinate data representing the movable position of the stick 21, and Only the operation information of the execution key 22 to be determined is sufficient. As a result, the bus 30 connecting the operation device 20 and the display device 10 can be made low speed, and simplification and cost reduction of the entire system can be achieved.

  In the display device 10 in the above embodiment, the coordinate data of the switch data management table includes valid coordinate data to which any switch is assigned and invalid coordinate data to which any switch is not assigned. 11 (specifically, step S24 to step S28) when the coordinate data acquired by the control unit 11 (specifically step S21) corresponds to the effective coordinate data when a new menu is displayed on the display unit 13. If the coordinate data acquired by the control unit 11 (specifically, step S21) corresponds to invalid coordinate data without correcting the switch assignment contents, any switch is assigned to invalid coordinate data. In addition, the switch assignment is corrected.

  Thereby, when a new menu is displayed on the display unit 13, if the movable position of the stick 21 corresponds to the effective coordinate data, the assigned switch on the display unit 13 is selected as it is, Even when the movable position of the stick 21 corresponds to invalid coordinate data, any one of the switches on the display unit 13 can be selected. As a result, the user can immediately perform the selected switch execution operation, another switch selection operation, and the like, and the user operability can be improved.

  In the display device 10 in the above embodiment, the coordinate data of the switch data management table is coordinate data of a two-dimensional coordinate system composed of the X coordinate and the Y coordinate, and the control unit 11 (specifically, Steps S24 to S28) When the coordinate data acquired by the control unit 11 (specifically, step S21) corresponds to invalid coordinate data when a new menu is displayed on the display unit 13, the invalid coordinate data and the Y coordinate are the same. If valid coordinate data exists, search for valid coordinate data having the maximum X coordinate among the valid coordinate data, and assign the switch so that the switch corresponding to the valid coordinate data is assigned to the invalid coordinate data. Correct the contents.

  Thereby, when a new menu is displayed on the display unit 13, the movable position within the movable range of the stick 21 and the display position of the cursor C on the screen of the display unit 13 can be roughly matched. it can. As a result, the user can subsequently perform the selected switch execution operation or another switch selection operation without a sense of incongruity, thereby improving the operability of the user.

  In the display device 10 in the above embodiment, the coordinate data of the switch data management table is coordinate data of a two-dimensional coordinate system composed of the X coordinate and the Y coordinate, and the control unit 11 (specifically, Steps S24 to S28) When the coordinate data acquired by the control unit 11 (specifically, step S21) corresponds to invalid coordinate data when a new menu is displayed on the display unit 13, the invalid coordinate data and the Y coordinate are the same. If there is no valid coordinate data, the Y coordinate of the invalid coordinate data is increased / decreased to search for valid coordinate data having the same X coordinate and different Y coordinate as the invalid coordinate data, and the switch corresponding to the valid coordinate data is invalid. The switch assignment is corrected so that it is assigned to the coordinate data.

  Thereby, on the screen of the display unit 13, even when there is no switch in the left-right direction (direction corresponding to the X coordinate) of the display position corresponding to the movable position of the stick 21, the vertical direction (corresponding to the Y coordinate). When there is a switch in the direction), the cursor C can be displayed on the switch. As a result, the movable position of the stick 21 within the movable range and the display position of the cursor C on the screen of the display unit 13 can be roughly matched.

  In the display device 10 in the above embodiment, the storage unit 14 (corresponding to the storage unit) that stores the coordinate data acquired by the control unit 11 (specifically, step S8 and step S21), and the coordinates stored in the storage unit 14 The control unit 11 (in detail, step S10 in detail) detects the presence / absence of the operation of the stick 21 by comparing the data with the coordinate data acquired after acquiring the coordinate data in the control unit 11 (in detail, step S8). Control that updates the coordinate data stored in the storage unit 14 to the current coordinate data when it is detected that the stick 21 is operated by the control unit 11 (specifically, step S10). 11 (in detail, step S36, corresponding to coordinate data updating means).

  Thus, the control unit 11 (specifically, step S10) compares the coordinate data stored in the storage unit 14 with the current coordinate data acquired by the control unit 11 (specifically, step S8), and the stick 21 When it is determined that it has been operated, the control unit 11 (specifically, step S36) updates the coordinate data stored in the storage unit 14 to the current coordinate data, thereby constantly monitoring whether the user has operated the stick 21 or not. can do.

  In the display device 10 according to the above embodiment, the coordinate data stored in the storage unit 14 is compared with the coordinate data acquired after the coordinate data is acquired by the control unit 11 (specifically, step S8). The control unit 11 (specifically, step S31, which corresponds to the relative displacement detection means) that detects the relative displacement of the movable position 21 includes the control unit 11 (specifically, step S33). Corrects the switch assignment based on the relative displacement detected in step S31).

  Accordingly, the switch C can be selected by moving the cursor C displayed on the display unit 13 so as to match the operation direction and operation amount of the stick 21 by the user. Thereby, a user's operativity can be maintained favorable.

  In the display device 10 in the above embodiment, the control unit 11 (specifically, step S33) causes the control unit 11 (specifically, step S31) to change the effective coordinate data and the effective coordinate data from the position where the stick 21 corresponds to the effective coordinate data. When it is detected that a position corresponding to the adjacent invalid coordinate data is operated, the switch assignment is corrected so that the switch corresponding to the valid coordinate data before the operation is assigned to the invalid coordinate data after the operation. .

  Thus, when the switch at the screen end is selected in the menu displayed on the display unit 13, even if the user accidentally operates the stick 21 further in the end direction, the cursor C is displayed on the display unit 13. It can be prevented from moving. As a result, even when an erroneous operation as described above is performed, it is possible to prevent the cursor C from disappearing from the screen or moving in a direction not corresponding to the operation direction of the stick 21 and to improve the operability. Can be maintained.

  In the display device 10 in the above embodiment, the control unit 11 (specifically, step S33) causes the control unit 11 (specifically, step S31) to change the effective coordinate data and the effective coordinate data from the position where the stick 21 corresponds to the effective coordinate data. When it is detected that the operation is performed to a position corresponding to the adjacent invalid coordinate data, and then the operation is performed from the position corresponding to the invalid coordinate data after the operation to the position corresponding to the other coordinate data, the stick 21 is operated. The switch assignment content is corrected so that the operation is the same as when the operation is performed in the direction corresponding to the other coordinate data from the position corresponding to the previous valid coordinate data.

  Accordingly, even when the user further operates the stick 21 in the operation direction corresponding to the end direction in the state where the switch at the screen end is selected in the menu displayed on the display unit 13, the cursor is displayed on the display unit 13. When C does not move and the user subsequently operates the stick 21 in the direction opposite to the end direction, the user immediately opposes the cursor C without waiting for the stick 21 to return to the original coordinate position. Can be moved in the direction. As a result, the user can quickly perform another switch selection operation or the like thereafter, and the operability of the user can be further improved.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described in order.

(1) When further correction is performed so that all the switches on the menu can be selected When not specifically described in the above embodiment, a switch that cannot be selected depending on the operation mode of the stick 21 occurs in the display processing of the above embodiment. There is. In order to avoid such a problem, the present modification adds correction in a multiplicative manner in addition to the correction of the assignment contents in the above embodiment.

  FIG. 40 is a diagram illustrating an example of the movable operation of the stick 21 when such a problem occurs, and FIG. 41 is a diagram illustrating an example of the switch data of the switch SW13 stored in the record of the coordinate data X2Y4. . FIG. 42 is a diagram illustrating an example of the correction of the switch assignment content similar to that of the above embodiment performed in this case, and FIG. 43 illustrates the correction when the switch assignment content is further corrected in this modification. It is a figure showing an example.

  Consider the case where the stick 21 is operated from the coordinate data X2Y4 to the coordinate data X5Y5 as shown in FIG. First, when the stick 21 is operated in the right direction from the coordinate data X2Y4 to the coordinate data X5Y4, as shown in FIG. 41, the right movement destination data of the switch data corresponding to the coordinate data X2Y4 before the operation is the same coordinate data. Since it is X2Y4, the record does not move as in the case shown in FIG. That is, the switch assigned by the correction remains the switch SW13. When the stick 21 is operated downward from the coordinate data X5Y4 toward the coordinate data X5Y5, as shown in FIG. 41, the downward movement destination data of the switch data corresponding to the coordinate data X2Y4 becomes the coordinate data X2Y5. Therefore, as shown in FIG. 42, the switch SW15 corresponding to the coordinate data X2Y5 is assigned to the coordinate data X5Y5. In this case, when the user subsequently operates the stick 21 to the right in order to select the switch SW16, the switch SW17, or the switch SW18, the right movable range of the stick 21 is up to the coordinate data X7Y5. Only minutes can be operated. Therefore, the switches SW16 and SW17 can be selected, but the switch SW18 cannot be selected. Such a problem also occurs when the stick 21 is operated from the coordinate data X2Y4 to the coordinate data X6Y5 or the coordinate data X7Y5. In the former case, the switches SW17 and SW18 are used, and in the latter case, the switch SW16 is used. , SW17, SW18 cannot be selected.

  Therefore, in this modification, further correction is made to the switch assignment contents for the coordinate data in the switch data management table, and in the case of the movable operation shown in FIG. 40, the stick 21 moves from the coordinate data X5Y4 to the coordinate data X5Y5. As shown in FIG. 43, when the operation is performed in the downward direction, the assignment content is corrected so that the switch SW16 corresponding to the coordinate data X3Y5 is assigned to the coordinate data X5Y5. Thereby, the user can select both of the switches SW17 and SW18 thereafter. When the stick 21 is operated from the coordinate data X2Y4 to the coordinate data X6Y5 or the coordinate data X7Y5, the switch SW17 corresponding to the coordinate data X4Y5 is assigned in the former case, and the coordinate data X5Y5 in the latter case. The assignment content may be corrected so that the switch SW18 corresponding to is assigned. In this way, by further correcting the assigned content, the user can surely select all the switches on the menu regardless of the operation mode of the stick 21.

(2) When correction is performed according to the display size of the switch In the above embodiment, the display size in the vertical direction of each switch in the menu (that is, the height of the switch) is exemplified in each row. If the display size in the vertical direction differs greatly, the switch layout in the menu and the coordinate data arrangement in the switch data management table do not match well, and each switch is displayed in the menu with respect to the coordinate data in the switch data management table. Cannot be assigned according to In such a case, the cursor C may perform an operation different from the user's intention on the display unit 13. In this modification, in order to avoid such a problem, correction is performed based on the difference in the display size of the switch in the menu.

  FIG. 44 is a diagram illustrating an example of a menu including switches that have greatly different display sizes in the vertical direction, FIG. 45 is a diagram illustrating an example of correction of switch assignment contents in the present modification, and FIG. It is a figure showing an example of the switch data management table which updated the allocation content.

  The menu shown in FIG. 44 is an example of a menu for playing CD music on the audio device. This menu includes switches SW21, SW22, SW24 to SW27 whose display sizes in the vertical direction are substantially the same, and a switch SW23 whose display size in the vertical direction is more than twice these switches SW21, SW22, SW24 to SW27. ing. For example, the image data of the CD jacket being reproduced is reduced and displayed in the switch SW23 portion, and when the user operates the switch SW23, the image of the CD jacket can be enlarged and displayed.

  When SW21 to SW27 of the menu shown in FIG. 44 are assigned to coordinate data as in the above embodiment, coordinate data X2Y3 becomes invalid coordinate data as shown in FIG. In this case, for example, when the stick 21 is positioned at the coordinate data X1Y3 and the switch SW24 is selected as shown in FIG. 44, the user moves the cursor 21 to the right in an attempt to move the cursor C from the switch SW24 to the switch 23. Even if it operates, the problem that the cursor C does not move may arise.

  Therefore, in the present modification, when the control unit 11 reads the switch data management table from the storage unit 14, the display size data of the switch data related to each switch stored in each record is acquired, and each switch in the menu is acquired. The switch assignment is corrected according to the difference in display size. Specifically, when the stick 21 is operated from the coordinate data X1Y3 to the coordinate data X2Y3 in the right direction, as shown in FIG. 45, the switch SW23 corresponding to the coordinate data X2Y2 is assigned to the coordinate data X2Y3. Correct. Such correction of switch assignment can be realized by setting X2Y2 (SW23) as the right destination data of the switch data related to the switch SW24 of the coordinate data X1Y3. Accordingly, the user can move the cursor C from the switch SW24 to the switch 23. As described above, the cursor C can be operated on the display unit 13 so as to match the user's intention by correcting the switch assignment contents according to the difference in display size of each switch in the menu. Thereby, user operability can be improved.

  In the above description, the correction is made by correcting the switch assignment contents. However, for example, as shown in FIG. 46, the switch assignment itself in the switch data management table may be changed. In this example, the switch 23 is assigned adjacent to the coordinate data of both the switch SW22 and the switch SW24. This also allows the user to move the cursor C from the switch SW24 to the switch 23.

(3) When correction is performed according to the number of switches For example, when the menu includes only four switches of 2 rows and 2 columns, the number of switches in the menu in the vertical direction and the number in the horizontal direction are switch data management. When the number of coordinate data in the Y coordinate direction and X coordinate direction of the table is small, when the four switches are assigned from the upper left of the coordinate data in the switch data management table as in the above embodiment, the stick 21 Although the cursor C is located in the upper left area from the center of the movable range, the display unit 13 may display the cursor C on the opposite lower right switch. In such a case, the user feels uncomfortable. In this modification, in order to avoid such a problem, when a new menu is displayed, correction is performed based on the number of switches in the menu.

  47 is a diagram illustrating an example of a menu including four switches in 2 rows and 2 columns, FIG. 48 is a diagram illustrating an example of a switch data management table corresponding to the menu illustrated in FIG. 47, and FIG. FIG. 10 is a diagram illustrating an example of correction of switch assignment contents in the present modification.

  The menu shown in FIG. 47 is an example of a main menu that is displayed first when the display device is powered on, for example. This menu includes four switches SW31 to SW34 in two rows and two columns. When these switches SW31 to SW34 are assigned to coordinate data in the same manner as in the above embodiment, the result is as shown in FIG. In this case, although the movable position of the stick 21 is located in the upper left region from the center of the movable range as shown in FIG. 48, the opposite lower right switch SW34 is displayed on the display unit 13 as shown in FIG. The cursor C is displayed on the top, resulting in a feeling of strangeness for the user.

  Therefore, in this modification, the ratio of the number of switches in the vertical direction in the menu to the number of coordinate data in the Y coordinate direction of the switch data management table and the number of coordinate data in the X coordinate direction of the switch data management table The allocation contents of the switches are corrected according to the ratio of the number of switches in the horizontal direction. Specifically, as shown in FIG. 48, the number of switches in the menu in the Y coordinate direction in the switch data management table is 6, and the number of switches in the vertical direction is 2, 3 and 4, respectively. 49, the contents of switch assignment are corrected by replacing the Y coordinate as shown in FIG. In this example, when the number of switches in the vertical direction is 1, 5, or 6, the Y coordinate is not read.

  For example, in the case of the menu shown in FIG. 47, the number of switches in the menu in the vertical direction is 2. Therefore, as shown in FIG. In the case of Y6, read as Y2. As a result, for example, when the stick 21 is located between the coordinate data X1Y1 and X1Y3, the cursor C is displayed on the switch SW31 assigned to the coordinate data X1Y1, and the stick 21 is located between the coordinate data X1Y4 and X1Y6. The cursor C is displayed on the SW 33 assigned to the coordinate X1Y2. Further, although not shown, the X-coordinate is corrected by the same replacement as described above. Thereby, when the stick 21 is positioned in the upper left area from the center of the movable range, the same upper left switch can be selected on the screen of the display unit 13. Note that these replacements are performed only when the display position of the cursor C is obtained using a new menu, and the coordinate data stored to determine whether or not the stick 21 is operated is stored as it is. After the cursor C is displayed in a new menu, this correction is not performed until another menu is displayed. As described above, according to this modification, when a new menu is displayed, the movable position of the stick 21 within the movable range and the display position of the cursor C on the screen of the display unit 13 are generally matched. Therefore, the user's uncomfortable feeling can be eliminated and the operability can be improved.

  In the above description, the stick 21 is rotated in the operation device 20. However, the present invention is not limited to this. For example, the stick 21 may be configured to slide on a plane.

  In the above description, the switch data management table data itself is not rewritten, and the switch assignment contents for the coordinate data in the table are corrected. However, the present invention is not limited to this, and the switch data management table reflects the correction contents. The data may be updated.
