JP 10-38593 A

When using a display that moves up and down by an electric mechanism between the housing position where the display surface is hidden and the use position where the display surface is exposed, a part of the display surface of the display is at an unpredictable height due to a failure of the electric mechanism. The display may become stationary when hidden.
In such a case, when information is displayed using the entire surface of the display screen, only a part of the information is visible to the user, and various problems occur. On the other hand, if the display on the display is completely stopped as a failure in such a case, the availability of the display of the user is completely lost.

Moreover, even when the user arbitrarily stops the display at a desired height, if the information can be appropriately presented using the display, the convenience of the display for the user can be further improved. .
Therefore, the present invention provides a display system capable of appropriately presenting information using the display even when the vertical position of the display is at a position where the display surface is hidden by an arbitrary size in the vertical direction. This is the issue.

  In order to achieve the above object, according to the present invention, in a display system including a display, the display is moved up and down between a lower position where all or a lower part of the display surface is hidden and an upper position where the entire display surface is exposed. Ascending / descending means, position detecting means for detecting the vertical position of the display, and a plurality of information presentation screens having different sizes in the vertical direction, the same kind of information being expressed in different expressions, are selectively displayed on the display. An information presentation screen output means to display and an exposed portion of the display surface of the display based on the vertical position of the display detected by the position detection means when the raising / lowering of the display stops Exposure size calculating means for calculating the vertical size. However, for each range of the vertical size of the exposed portion of the display surface of the display, any one of the plurality of information presentation screens has a vertical size display area within the range. The information presentation screen output unit is associated in advance as an information presentation screen suitable for presenting the used information, and the information presentation screen output unit calculates the vertical size of the exposed portion of the display surface of the display calculated by the exposure size calculation unit. Is selected from the plurality of information presentation screens as an information presentation screen to be displayed on the display.

  According to such a display system, even when the position of the display is a halfway position hidden by an arbitrary size of the display surface of the display, the display area of the size of the exposed portion of the display surface of the display at that time is reduced. An information presentation screen suitable for presenting the used information is selected and displayed on the display.

Therefore, even when the vertical position of the display is at a position where the display surface is hidden by an arbitrary size in the vertical direction, it is possible to appropriately present information using the display.
Here, in such a display system, in the exposure size calculation means, the display that is detected by the position detection means when the display is stopped due to a problem in raising and lowering the display by the lifting and lowering means. The vertical size of the exposed part of the display surface of the display may be calculated based on the vertical position of the display.

In this way, even when the display stops at an intermediate position that is hidden by an arbitrary size on the display surface of the display due to a failure in the lifting function of the display, information is appropriately presented using the display. Will be able to.
Alternatively, in such a display system, the lifting means lifts and stops the display according to a user operation. In the exposure size calculation means, the lifting means moves the display according to a user operation. When stopped, the vertical size of the exposed part of the display surface of the display may be calculated based on the vertical position of the display detected by the position detecting means.

In this way, even when the user arbitrarily places the display at a desired height, information can be appropriately presented using the display.
In addition, in such a display system, each of the information presentation screens is larger than the vertical size of the information presentation screen and smaller than the vertical size of the information presentation screen having the next largest vertical size after the information presentation screen. It may be configured to correspond in advance to the range of the vertical size of the exposed part of the display surface of the display.

By doing in this way, it can be ensured that the whole information presentation screen is always displayed on the exposed part of the display surface of the display.
Alternatively, such a display system corresponds to each information presentation screen in advance with respect to the range of the vertical size of the exposed part of the display surface of the display, including the vertical size of the information presentation screen. In addition, in the information presentation screen output means, the selected information presentation screen is obtained by calculating the vertical size of the information presentation screen, and the upper and lower portions of the display surface of the display calculated by the exposure size calculation means. You may comprise so that it may display on the said display, after enlarging or reducing so that it may correspond to direction size.

By doing so, the size of the exposed portion of the display surface of the display and the size of the information presentation screen can be made equal, and the visibility can be obtained using all of the exposed portion of the display surface of the display. The information can be presented to the user well.
The display system described above may be a system mounted on an automobile, and the elevating means displays the display at a lower position where all or a lower part of the display surface is hidden below the upper surface of the dashboard of the automobile. The entire surface may be raised or lowered between the upper position exposed on the upper surface of the dashboard.

  In addition, the display system described above may be a system mounted on an automobile, and the information presentation screen output means represents a plurality of pieces of information with different sizes in the vertical direction, representing current position and route information in different expressions. Any one of the presentation screens is selectively displayed on the display. The plurality of information presentation screens are smaller in size in the vertical direction. The information presentation screen further simplifies the current position and route information. It may be expressed in the expression.

  As described above, according to the present invention, it is possible to appropriately present information using the display even when the vertical position of the display is at a position where the display surface is hidden by an arbitrary size in the vertical direction.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 shows a configuration of a display system according to the present embodiment.
The display system according to the present embodiment is a system mounted on an automobile, and includes a navigation device 1, an input device 2, a display 3, an electric lifting device 4, and a position detection sensor 5, as shown in the figure.
Here, as shown in FIGS. 2a to 2c, the display 3 has a display surface facing toward the inside of the vehicle, and is entirely buried in the upper surface of the dashboard 10 of the automobile shown in FIG. 2a so that the entire display surface is hidden. It is provided so as to be vertically movable between the position and the upper end position at which the entire display surface is exposed on the upper surface of the dashboard 10 of the automobile of FIG. And it is the electric elevator 4 that raises and lowers the display 3 like this. The position detection sensor 5 is a sensor such as a linear position meter that detects the vertical position of the display 3 that is lifted and lowered by the electric lifting device 4 in this way.

Next, the navigation device 1 is a device that calculates a current position of a car, calculates a route to a destination, and guides the user to the current position and route by displaying a predetermined guidance screen on the display 3. is there.
Here, the navigation device 1 includes a full guidance screen display mode, a half guidance screen display mode, and a quarter guidance screen display mode as display modes. In addition, three types of guidance screens can be generated as a guidance screen: a full guidance screen, a half guidance screen, and a quota guidance screen. Depending on the display mode, either the full guidance screen, the half guidance screen, or the quota guidance screen is displayed. , Selectively displayed on the display 3. In addition, the navigation device 1 enlarges / reduces the full guidance screen, the half guidance screen, and the quota guidance screen in the vertical direction according to the set enlargement / reduction ratio and displays them on the display 3.

  More specifically, the navigation device 1 sets the full guidance screen in the full guidance screen display mode, the half guidance screen in the half guidance screen display mode, and the quota guidance screen in the quarter guidance screen display mode at that time. The image is enlarged / reduced according to the enlargement / reduction ratio being displayed, and displayed on the display 3 in an arrangement in which the upper end of the guide screen is aligned with the upper end of the display surface of the display 3.

Here, FIG. 3 shows examples of a quota guidance screen, a half guidance screen, and a full guidance screen.
In the figure, a1 represents a quota guidance screen, b1 represents a half guidance screen, and c1 represents a full guidance screen.
As shown in the figure, the quota guidance screen is generated as a screen whose horizontal size is equal to the horizontal size of the display surface of the display 3 and whose vertical size is 1/4 of the vertical size of the display surface of the display 3. Is done. The half guidance screen is generated as a screen having a horizontal size equal to the horizontal size of the display surface of the display 3 and a vertical size having a size that is ½ of the vertical size of the display surface of the display 3. The full guidance screen is generated as a screen having a horizontal size equal to the horizontal size of the display surface of the display 3 and a vertical size equal to the vertical size of the display surface of the display 3.

  The full guidance screen is a screen that displays detailed road guidance information, and is a screen that displays the current position and route on a regular map. The half guidance screen is a screen that displays simplified road guidance information, and is a screen that displays the current position and route on a simple map that schematically represents only roads around the route. The quota guidance screen is a screen that displays further simplified route guidance information, and is a screen that represents only the distance from the current location to the destination and the right / left turn point.

Hereinafter, the elevation control process performed by the navigation device 1 in such a configuration will be described.
FIG. 4 shows the procedure of the elevation control process.
As shown in the figure, in this process, the navigation device 1 generates a lowering instruction operation of the display 3 from the user using the input device 2 (step 402) and the display 3 is lifted from the user using the input device 2. The occurrence of an instruction operation (step 404) is monitored.

  Then, if an operation to raise the display 3 is generated (step 404), it is checked whether or not the display 3 is in the uppermost position, which is the highest position where the display 3 can be raised, with reference to the position detection sensor 5 (step 406). If it is at the upper end position, the process returns to the monitoring of steps 402 and 404.

  On the other hand, if it is not at the upper end position, the electric elevator 4 is controlled to start raising the display 3 (step 408), and a timer having a predetermined timeout time is started (step 410). Here, the timer sets a time sufficient for the display 3 to rise to the upper end position after the display 3 starts to rise by the electric lifting device 4.

  Then, the occurrence of reaching the upper end position of the display position represented by the position detection sensor 5 (step 412), the occurrence of an operation for stopping the raising of the display 3 from the user using the input device 2 (step 414), and the timeout of the timer (Step 416), and if any of them occurs, the electric elevator 4 is controlled to stop the display 3 from being raised (step 418). Then, the process proceeds to step 420.

  On the other hand, if an instruction to lower the display 3 is generated in step 402 (step 402), it is checked whether or not the display 3 is at the lowermost position that is the lowest position where the display 3 can be lowered with reference to the position detection sensor 5. (Step 436) If it is in the lower end position, the process returns to the monitoring of Steps 402 and 404.

  On the other hand, if it is not in the lower end position, the electric elevator 4 is controlled to start the lowering of the display 3 (step 438), and a timer having a predetermined timeout time is started (step 440). Here, the timer sets a time sufficient for the display 3 to descend to the lower end position after the display 3 starts to descend by the electric lifting device 4.

  Then, the occurrence of reaching the lower end position of the display position represented by the position detection sensor 5 (step 442), the occurrence of the descent stop operation of the display 3 from the user using the input device 2 (step 444), and the timer timeout (Step 446) is monitored, and if any of them occurs, the electric elevator 4 is controlled to stop the lowering of the display 3 (Step 448). Then, the process proceeds to step 420.

Note that the timeout detected in steps 416 and 446 of the above processing occurs when the display 3 cannot be moved up and down normally due to a failure of the electric lifting device 4 or the like.
When the process proceeds from step 418 or 448 to step 420 in this way, the display opening is calculated from the display position represented by the position detection sensor 5. Here, the display opening is calculated as a ratio of the vertical size of the portion of the display surface of the display 3 exposed on the dashboard 10 to the vertical size of the entire display surface of the display 3. That is, if the position of the display 3 is such that only the upper half of the display surface of the display 3 is exposed on the dashboard 10, the display opening degree is 50%, and only a quarter of the display surface of the display 3 is If it exists in the position exposed on the dashboard 10, the display opening will be 25%.

  Then, it is checked whether or not the calculated display opening is less than the threshold value TH (step 422). If it is less than the threshold value TH, the display of the guidance screen on the display 3 is stopped (step 426), Return to the monitoring of steps 402 and 404. Here, the threshold value TH is, for example, 19%.

On the other hand, if the calculated display opening is not less than the threshold value TH (step 422), the above-described display mode and enlargement / reduction ratio are set according to the display opening (step 424). Return to monitoring.
Here, the display mode and the enlargement / reduction ratio according to the display opening are set as follows.
That is, if the display opening is 19% or more and less than 38%, the display mode is set to the quarter guidance screen display mode, and if the display opening is 38% or more and less than 75%, the display mode is set to the half guidance screen display mode. If the display opening is 75% or more, the display mode is set to the full guidance screen display mode.

  When the quota guidance screen display mode is set as the display mode, the display opening ÷ 25% is set as the enlargement / reduction ratio. When the half guidance screen display mode is set as the display mode, the display opening ÷ 50% is set. When setting as the enlargement / reduction ratio and setting the full guidance screen display mode as the display mode, set the display opening ÷ 100% as the enlargement / reduction ratio.

  By setting the display mode and the enlargement / reduction ratio, the quota guidance screen display mode is set when the display opening is 19% or more and less than 38%, and the quota guidance screen shown in FIG. 3a1 is as shown in FIG. 3a2. The display surface of the display 3 is enlarged / reduced in the vertical direction so as to be the same size as the portion exposed from the upper surface of the dashboard 10, and the display 3 and the display surface of the display 3 are aligned at the upper end. Displayed by arrangement. When the display opening is 38% or more and less than 75%, the half guide screen shown in FIG. 3b1 is the same size as the portion of the display surface of the display 3 exposed from the upper surface of the dashboard 10 as shown in FIG. 3b2. In such a manner, the image is enlarged / reduced in the vertical direction and displayed on the display 3 in a position arrangement aligned with the display surface of the display 3. When the display opening is 75% or more, the full guidance screen shown in FIG. 3c1 is the same size as the portion of the display surface of the display 3 exposed from the upper surface of the dashboard 10 as shown in FIG. 3c2. In addition, the image is enlarged / reduced in the vertical direction and displayed on the display 3 in a position arrangement aligned with the display surface of the display 3.

In the above, the raising / lowering control process which the navigation apparatus 1 performs was demonstrated.
According to the display system as described above, as shown in FIGS. 5a, 5b, and 5c, even when the display 3 is stationary at an intermediate position in the vertical direction due to a user operation or due to a failure or the like, Using the portion of the display surface that is exposed on the dashboard 10 at that time, it is possible to display the entire guide screen showing the current position and route information while ensuring the visibility.

  By the way, in the above embodiment, the enlargement / reduction ratio is set, and the quota guidance screen, half guidance screen, and full guidance screen are enlarged / reduced in the vertical direction at the set enlargement / reduction ratio. The setting of enlargement / reduction ratio and enlargement / reduction may not be performed. However, in this case, in order to ensure that the entire quarter guidance screen, half guidance screen, and full guidance screen are displayed on the exposed portion of the display surface of the display 3, the display opening is less than 25%. Stops the display on the display 3, and if the display opening is 25% or more and less than 50%, the display mode is set to the quota guidance screen display mode. If the display opening is 50% or more and less than 100%, the display mode is set. The half guidance screen display mode is set, and if the display opening is 100%, the display mode is set to the full guidance screen display mode.

  In the above embodiment, the case where the guidance screen of the navigation device 1 is displayed on the display 3 has been described as an example. However, in the present embodiment, the case where any information of any device is displayed on the display 3 is similarly described. Can be applied. In other words, in this case, in addition to the screen having the same size as the display surface of the display 3, the information in the vertical direction is ½ size and the vertical direction is ¼ size. It may be provided as a screen represented by the degree of conversion. However, the smaller the vertical size, the more simplified the information is expressed.

  Further, in the above embodiment, in addition to the full guidance screen having the same size as the display surface of the display 3, the half guidance screen in the vertical direction is ½ size and the quarter guidance screen in the vertical direction is ¼ size. Although two screens having different sizes in the vertical direction are used, any number of guide screens having a size in the vertical direction other than these sizes may be used.

In addition, the above embodiment can be similarly applied to a case where not all of the display surface of the display 3 but only a part of the lower side is hidden in a state where the display 3 is moved down most. .
Moreover, although the above embodiment demonstrated the case where the exposure amount of a display surface increased as the display 3 moved from the bottom to the top, this embodiment displays each screen by the display surface of the display 3, and bottom end alignment. By doing so, the same can be applied to the case where the exposure amount of the display surface increases as the display 3 moves from top to bottom.
