The processor 101 is, for example, a CPU (Central Processing Unit). The CPU may be multi-core/multi-threaded and can execute multiple processes in parallel. The processor 101 implements various processing functions by executing control programs stored in the ROM 102 or NVM 104.

The ROM 102 stores control programs and control data that govern the operation of the multi-hierarchical map display device 1. RAM 103 is a main memory that functions as a working memory. The NVM 104 is a rewritable nonvolatile storage device such as an SSD (Solid State Drive). The NVM 104 stores an OS (Operating System), application programs (hereinafter, application programs are abbreviated as applications) for realizing various processing functions, data, and the like. The application stored in the NVM 104 includes all or part of a multi-layer map display program, which will be described later.

The display 105 is a display device such as a liquid crystal display.

The touch panel 106 is a touch input device placed on the display surface of the display 105. The multi-hierarchical map display device 1 can have operation keys other than the touch panel 106. The communication IF 107 is an interface unit that adopts a low-power wireless data communication standard such as Bluetooth (registered trademark). The communication IF 107 can further include a wireless communication interface unit, such as a mobile phone communication system such as 4G or 5G, a wireless LAN, or the like. The cameras 108 are for acquiring images, and can be provided on both the front and back surfaces of the multi-layer map display device 1, respectively. The sensor 109 detects various information related to the multi-hierarchical map display device 1 . The sensor 109 is, for example, a GPS (Global Positioning System) sensor that measures geographic position, an environmental sensor that measures temperature and atmospheric pressure, a gyro sensor or acceleration sensor that measures position and orientation, and a distance sensor that measures distance to the subject. Including sensors, etc.

FIG. 2 is a block diagram showing the functional configuration of the multi-hierarchical map display device 1 in relation to the hardware configuration shown in FIG. 1.

The processing unit 11 is composed of the processor 101 and a multi-hierarchical map display program stored in the NVM 104, and includes an elevation acquisition unit 111, a distance acquisition unit 112, a floor determination unit 113, and a floor determination unit 111 as software processing function units. A map drawing unit 114 is provided. All of these processing functional units are realized by causing the processor 101 to execute a multi-hierarchical map display program stored in the NVM 104. The processing unit 11 may also be implemented in various other forms including integrated circuits such as ASIC (Application Specific Integrated Circuit), DSP (Digital Signal Processor), FPGA (field-programmable gate array), GPU (Graphics Processing Unit), etc. It may be realized by

The storage unit 12 is composed of a ROM 102, a RAM 103, and an NVM 104, and includes a floor information table storage unit 121, a map data storage unit 122, an acquired information storage unit 123, and a determination result storage unit 124. Although not particularly illustrated, the storage unit 12 further includes a temporary storage unit that temporarily stores various data generated during processing operations of the processing unit 11.

Each part will be explained below.
The floor information table storage unit 121 of the storage unit 12 stores a floor information table that describes floor information for each facility. The floor information table storage unit 121 may be provided, for example, as part of a multi-hierarchical map display program, and may store floor information tables regarding a plurality of facilities in advance. Furthermore, if necessary, the floor information table of the facility to be displayed may be acquired from the cloud by the communication IF 107 and stored in the floor information table storage unit 121.

FIG. 3 is a diagram showing an example of the contents of one floor information table 121A stored in the floor information table storage section 121. The floor information table 121A is a table that describes a minimum altitude value altitude_min, a maximum altitude value altitude_max, and a threshold value threshold for each floor number. The minimum altitude value altitude_min and the maximum altitude value altitude_max are, for example, minimum and maximum values expressed in meters with the ground level altitude of the facility as a reference "0". The height of each floor differs from facility to facility, and even within one facility, the height may vary from floor to floor. The threshold value threshold may be a value in centimeters instead of meters, for example.

The map data storage unit 122 of the storage unit 12 stores map data of facilities. Similarly to the floor information table, the map data may also be provided, for example, as part of a multi-hierarchical map display program, or may be acquired from the cloud via the communication IF 107 if necessary. Alternatively, the map data may be acquired using a map application possessed by a smartphone functioning as the multi-hierarchical map display device 1. Note that the map data includes not only bitmap data or vector data for drawing a floor map image of the facility, but also attribute information such as the geographical location of the facility and the ground level elevation.

The altitude acquisition unit 111 of the processing unit 11 determines the altitude at which the multi-level map display device 1 is located based on the sensor output of the altitude sensor 109A and the ground level altitude of the facility stored in the map data storage unit 122. get. The altitude sensor 109A may be any type of sensor, such as a barometric pressure sensor, a combination of a barometric pressure sensor and a GPS sensor, or the like. The altitude acquisition unit 111 acquires the altitude of the multi-level map display device 1 based on, for example, the atmospheric pressure measured by the atmospheric pressure sensor and known information regarding the relationship between the atmospheric pressure and the altitude. The altitude acquisition unit 111 causes the acquired altitude to be stored in the acquired information storage unit 123 of the storage unit 12.

The distance acquisition unit 112 of the processing unit 11 acquires the distance from an arbitrary reference position, for example, the floor surface, to the multi-hierarchical map display device 1 based on the sensor output of the distance sensor 109B. The distance sensor 109B may be a sensor that measures the distance itself, such as a distance sensor, or may be a sensor that measures changes in the position and orientation of the multi-hierarchical map display device 1, such as an acceleration sensor. When using an acceleration sensor as the distance sensor 109B, the distance acquisition unit 112 can acquire the travel distance in an arbitrary time range. The distance acquisition unit 112 stores the acquired distance in the acquired information storage unit 123 of the storage unit 12.

The floor determination unit 113 determines the floor to be switched and displayed on the display 105 based on the altitude and distance stored in the acquired information storage unit 123 and the floor information table stored in the floor information table storage unit 121. A method for determining the floor to be switched and displayed will be described later. The floor determination unit 113 causes the determination result storage unit 124 to store the determination result of the floor to be switched and displayed.

The floor map drawing unit 114 reads map data of the floor to be switched and displayed from the map data storage unit 122 based on the determination result by the floor determination unit 113 stored in the determination result holding unit 124, and draws a floor map image. . The floor map drawing unit 114 displays the drawn floor map image on the display 105.

Next, the processing operation of the multi-hierarchical map display device 1 configured as above will be explained.
FIG. 4 is a flowchart showing the operation processing procedure of the multi-hierarchical map display device 1 according to the first embodiment. The processor 101 of the multi-hierarchical map display device 1 can perform the processing shown in this flowchart by executing the multi-hierarchical map display program stored in advance in the NVM 104.

The processor 101 first operates as the altitude acquisition unit 111 and displays the multi-layered map based on the sensor output of the altitude sensor 109A and the ground altitude in the map data of the facility at the current location acquired from the map data storage unit 122. The current altitude at which the device 1 is located is acquired (step S11). The processor 101 stores the acquired altitude in the acquired information storage unit 123 as the current altitude a.

Then, the processor 101 operates as the floor determining unit 113 and determines the current floor on which the multi-hierarchical map display device 1 is located based on the altitude stored in the acquired information holding unit 123 (step S12). For example, the processor 101 determines which floor number the current altitude a stored in the acquired information storage unit 123 corresponds to, based on the current facility floor information table 121A stored in the floor information table storage unit 121. That is, the processor 101
altitude_min ≦ a ＜ altitude_max
Determine the floor number that satisfies the condition. The processor 101 stores this determined floor number in the determination result holding unit 124 as the drawing floor floor.

The processor 101 operates as a floor map drawing unit 114 and draws a floor map from the map data stored in the map data storage unit 122 according to the drawing floor stored in the determination result storage unit 124, and displays it on the display 105. (Step S13).

Thereafter, the processor 101 determines whether or not there is an instruction to terminate through a predetermined user operation (step S14). If it is determined that a termination instruction has been given, the multi-hierarchical map display process shown in this flowchart is terminated.

On the other hand, if it is determined that there is no termination instruction, the processor 101 operates as the distance acquisition unit 112 and acquires the distance based on the sensor output of the distance sensor 109B (step S15). The processor 101 stores the acquired distance in the acquired information holding unit 123 as the first distance Li. Thereafter, the processor 101 waits for a predetermined t seconds to elapse (step S16). Then, after t seconds have elapsed, the processor 101 again operates as the distance acquisition unit 112 and acquires the distance based on the sensor output of the distance sensor 109B (step S17). The processor 101 stores the acquired distance in the acquired information holding unit 123 as the second distance Lt.

Then, the processor 101 operates as the floor determination unit 113, and first, from the first distance Li and the second distance Lt stored in the acquired information storage unit 123,
L = Lt - Li
By calculating , the vertical movement distance L of the multi-layer map display device 1 for t seconds is calculated (step S18).

Note that when an acceleration sensor is used as the distance sensor 109B, the processor 101 calculates the vertical movement distance L of the multi-level map display device 1 for t seconds based on the acceleration, instead of the processing in steps S15 to S17. The process can be changed to a process of acquiring and storing the acquired moving distance L in the acquired information holding unit 123. In that case, the process of step S18 can also be omitted.

The processor 101 determines the drawing floor based on the vertical movement distance L of the multi-level map display device 1 for t seconds (step S19). That is, the processor 101 uses the current facility floor information table 121A stored in the floor information table storage unit 121 to
F = L / threshold (round down to the nearest whole number)
Perform the calculation. Then, the value of the drawing floor floor stored in the determination result holding unit 124 is increased by +F using the obtained value of F, thereby updating the drawing floor floor. The processor 101 causes the determination result holding unit 124 to store the updated drawing floor floor.

In this way, the value of the drawing floor floor is updated according to the vertical movement distance L of the multi-hierarchical map display device 1. Conversely, if there is no vertical movement of the multi-hierarchical map display device 1, the value of the drawing floor floor will not be updated.

Thereafter, the processor 101 moves to the process of step S13 above. Then, in step S13, the processor 101 operates as the floor map drawing unit 114 and draws a floor map from the map data stored in the map data storage unit 122 according to the drawing floor floor stored in the determination result storage unit 124. It will be drawn and displayed on the display 105. That is, the displayed floor map is switched according to the vertical movement of the multi-hierarchical map display device 1, and the displayed floor map is maintained unless the multi-hierarchical map display device 1 is moved up and down.

FIG. 5 is a schematic diagram showing the relationship between the floor map and the display area 105A of the display 105 of the multi-hierarchical map display device 1. FIG. 5 shows an example of a four-story facility, and the map data storage unit 122 stores map data of four floor maps 122A1 to 122A4 for the facility. When the multi-hierarchical map display device 1 is activated, for example, if the user is on the fourth floor, it is determined in step S12 that the current floor is the fourth floor. In this case, in the next step S13, as illustrated in FIG. 105. Here, when the user moves the multi-hierarchical map display device 1 downward by, for example, 7 cm, F=7/5=1 in step S19, and the third floor one floor below is determined as the drawing floor. As a result, when the process returns to step S13, a portion of the floor map 122A3 for the third floor corresponding to the display area 105A centered on the user's current position is displayed on the display 105 at a predetermined magnification.

For example, if the user is on the 4th floor and moves the multi-hierarchical map display device 1 downward by 12 cm, F=12/5=2 in step S19, and the 2nd floor two floors below is determined as the drawing floor. be done. As a result, when the process returns to step S13, the display is switched from the fourth floor floor map 122A4 to the second floor floor map 122A2.

Although not shown in the flowchart of FIG. 4, the map can be enlarged/reduced by the user's known pinch-out/pinch-in operations on the touch panel 106. When switching the display of the floor map from step S19 to step S13, the display magnification of the floor map before switching may be inherited instead of the prescribed magnification.

As described in detail above, the multi-level map display device 1 according to the first embodiment of the present invention is a floor map display unit that displays a single-level floor map in the display area 105A of the display 105 in a facility having multiple levels. A map drawing unit 114, a distance acquisition unit 112 as a measurement unit that measures the amount of physical displacement with respect to the detection target object, and a hierarchy of the floor map to be displayed on the display unit according to the amount of displacement measured by the measurement unit. A floor determination unit 113 is provided as a control unit for changing.
Therefore, according to the multi-hierarchical map display device 1 according to the first embodiment, the hierarchy of the displayed floor map can be switched according to the physical displacement of the detection target given by the user. Therefore, the user can intuitively and easily switch between floor maps of a multi-level facility.

Further, in the multi-hierarchical map display device 1 according to the first embodiment, the elevation acquisition unit 111 as a measuring unit further measures the altitude at which the multi-hierarchical map display device 1 is located, and the display unit The floor map of the current hierarchy of the multi-hierarchical map display device 1, which is determined based on the altitude measured by the controller, is initially displayed in the display area 105A.
Therefore, according to the first embodiment, the floor map of the floor where the user is located, which the user would like to view, can be displayed first, and the user's effort can be reduced.

The multi-hierarchical map display device 1 according to the first embodiment further includes a floor information table storage unit 121 as a storage unit that stores a threshold value regarding the amount of displacement, and the floor determination unit 113 as a control unit has a measuring unit. It is determined whether the measured displacement amount is larger than a threshold value stored in the storage section, and if it is larger, the hierarchy of the floor map displayed on the display section is changed.
Therefore, according to the first embodiment, even if the conditions regarding the amount of displacement differ from facility to facility, by storing the conditions as threshold values, it is possible to appropriately switch and display the floor map according to the facility. It becomes possible.

Further, in the multi-hierarchical map display device 1 according to the first embodiment, the detection target is the multi-hierarchical map display device 1, and the distance acquisition unit 112 as a measuring unit detects the displacement amount of the multi-hierarchical map display device 1. The floor determining section 113, which serves as a control section, changes the hierarchy of the floor map displayed on the display section according to the moving distance measured by the measuring section.
Therefore, according to the first embodiment, it is possible to switch the displayed floor map up and down by moving the multi-hierarchical map display device 1 up and down, and it is possible to realize an intuitive operation for the user.

Here, the multi-hierarchical map display device 1 according to the first embodiment further includes a floor information table storage unit 121 as a storage unit that stores the threshold value of the moving distance, and the floor determination unit 113 as a control unit has a measuring unit. When the moving distance measured by is larger than the moving distance threshold stored in the storage section, the hierarchy of the floor map displayed on the display section is changed.
Therefore, according to the first embodiment, even if the conditions regarding travel distance differ from facility to facility, by storing the conditions as thresholds, it is possible to appropriately switch and display floor maps according to the facility. It becomes possible.

Note that the storage unit stores a threshold value for each floor of the facility, and the floor determination unit 113 as a control unit determines whether the moving distance measured by the measurement unit is lower than the threshold value for a plurality of floors stored in the storage unit. If the size is large, the floor map displayed on the display unit is changed by multiple levels.
Therefore, by moving the multi-hierarchical map display device 1 largely, it becomes possible to switch the floor map to two or more levels at once.

Further, in the multi-hierarchical map display device 1 according to the first embodiment, the measurement unit further measures the moving direction of the multi-hierarchical map display device 1 in the direction of gravity as the amount of displacement, and the floor determination unit 113 as a control unit changes the hierarchy of the floor map displayed on the display unit to the floor map of the hierarchy in the movement direction measured by the measurement unit when the movement distance is greater than the threshold value.
Therefore, according to the first embodiment, if the multi-hierarchical map display device 1 is moved upward, the floor map can be switched to the floor map on the upper floor, and conversely, if the multi-hierarchical map display device 1 is moved downward. You can switch to the floor map of the floor below. Therefore, it is possible to realize an intuitive operation for the user.

Note that the distance acquisition unit 112 as a measurement unit measures the movement direction and movement distance in the gravity direction of the multi-hierarchical map display device 1 at a prescribed time interval using a distance sensor 109B that is a distance sensor or an acceleration sensor. be able to.

[Second embodiment]
Next, a second embodiment of the invention will be described. The second embodiment is an example in which the floor map is switched depending on the size of the pinch-out/pinch-in operation. In the following description, parts similar to those in the first embodiment will be given the same reference numerals as those used in the first embodiment, and the description thereof will be omitted.

FIG. 6 is a block diagram showing an example of the functional configuration of the multi-hierarchical map display device 1 according to the second embodiment. This embodiment does not have the distance sensor 109B and the distance acquisition section 112 of the processing section 11 of the first embodiment. Instead, the processing unit 11 includes a pinch-out/pinch-in determination unit 115 as a processing function unit.

The pinch-out/pinch-in determination unit 115 determines whether a known pinch-out/pinch-in operation has been performed by the user on the touch panel 106, and acquires the size thereof. That is, the pinch-out/pinch-in determination unit 115 determines whether it is a pinch-out operation or a pinch-in operation, depending on the movement direction of the user's two fingers, that is, whether the two fingers are moving away from each other or toward each other. Determine whether it is. Furthermore, the pinch-out/pinch-in determining unit 115 obtains the size of the pinch-out/pinch-in from the positions before and after the movement of the two fingers. The pinch-out/pinch-in determining unit 115 causes the determination result holding unit 124 to store the determination result of the pinch-out/pinch-in operation, that is, the presence or absence and size of the acquired pinch-out/pinch-in.

Furthermore, in the multi-hierarchical map display device 1 according to the second embodiment, the contents of the floor information table stored in the floor information table storage unit 121 of the storage unit 12 are different from those in the first embodiment.

FIG. 7 is a diagram showing an example of the contents of one floor information table 121A stored in the floor information table storage unit 121 in the second embodiment. The floor information table 121A is a table that describes a minimum altitude value altitude_min, a maximum altitude value altitude_max, a map area map, a first threshold value threshold_1, and a second threshold value threshold_2 for each floor number. The minimum altitude value altitude_min and the maximum altitude value altitude_max are as described in the first embodiment. The map area map is expressed as a percentage. Of course, an actual area value may be used. The first threshold value threshold_1 is a threshold value for determining whether to switch to the floor map of the lower floor, and the second threshold value threshold_2 is a threshold value for determining whether to switch to the floor map of the upper floor.

FIG. 8 is a schematic diagram showing the relationship between the floor map 122A, the display area 105A of the multi-hierarchical map display device 1, and the display floor area 122B displayed in the display area 105A. The first and second threshold values threshold_1 and threshold_2 in the floor information table 121A are the percentage of the entire floor map 122A of the corresponding layer occupied by the display floor area 122B, which is the part of the floor map displayed in the display area 105A. It is a value. That is, "0.1" of the first threshold value threshold_1 in the example of FIG. 7 corresponds to the case where the display floor area 122B is 10% of the floor map 122A, and "1" of the second threshold value threshold_2 corresponds to This corresponds to the case where the floor area 122B is 10% of the entire floor map 122A.

Note that the values of the first and second thresholds threshold_1 and threshold_2 may be determined by default, or may be configured so that they can be set or rewritten by the user at any timing.

Next, the processing operation of the multi-hierarchical map display device 1 configured as above will be explained.
FIG. 9 is a flowchart showing the operation processing procedure of the multi-hierarchical map display device 1 according to the second embodiment. Here, the processing from step S11 to step S14 is as described in the first embodiment.

If it is determined in step S14 that there is no termination instruction, the processor 101 operates as the pinch-out/pinch-in determining unit 115 and determines whether the user has performed a pinch-out operation or a pinch-in operation on the touch panel 106 ( Step S21). If it is determined that neither a pinch-out nor a pinch-in operation has been performed, the processor 101 moves to the process of step S14.

On the other hand, if it is determined that a pinch-out operation or a pinch-in operation has been performed, the processor 101 operates as the floor map drawing unit 114 and updates the display (step S22). That is, in response to the pinch-out operation or pinch-in operation, the processor 101 enlarges or reduces the floor map of the current floor being displayed based on the pinch-out/pinch-in size stored in the determination result holding unit 124. A map is drawn and displayed on the display 105.

After that, the processor 101 operates as the floor determination unit 113 and calculates the display area ratio (step S23). That is, the processor 101 uses the map area map, which is the area of the floor map of the floor indicated by the drawing floor stored in the determination result storage unit 124, of the current facility stored in the floor information table storage unit 121. Obtained from the floor information table 121A. Then, the processor 101 calculates the ratio b based on the acquired map area map and the area display_area of the display floor area 122B displayed in the display area 105A updated in step S22.
b = display_area / map (0 ≦ b ≦ 1)
Calculated by

FIG. 10 is a schematic diagram showing changes in the display floor area 122B occupying the floor map 122A due to the pinch-out operation and the pinch-in operation. When a pinch-out operation is performed in the state shown in the upper left of FIG. 9, the floor map 122A displayed in the display area 105A is enlarged, as shown in the lower left of FIG. When the floor map 122A is enlarged, the area of the display floor area 122B occupying the floor map 122A becomes smaller, and the value of the ratio b also becomes smaller. Furthermore, when a pinch-in operation is performed in the state shown in the upper left of FIG. 9, the floor map 122A displayed in the display area 105A is displayed in a reduced size, as shown in the upper right of FIG. When the floor map 122A is reduced, the area of the display floor area 122B that occupies in the floor map 122A increases, and the value of the ratio b also increases.

Next, the processor 101 determines whether the calculated ratio b is smaller than the first threshold threshold_1 of the drawing floor floor in the floor information table 121A, that is,
b < threshold_1
It is determined whether or not (step S24).

Here, if the ratio b is smaller than the first threshold threshold_1, the processor 101 determines one floor above as the drawing floor (step S25). That is, in the case of b < threshold_1, the processor 101 stores in the determination result holding unit 124 a value obtained by adding “+1” to the value of the drawing floor floor stored in the judgment result holding unit 124 as the new drawing floor value. let After that, the processor 101 moves to the process of step S13 described above. Then, in step S13, the processor 101 operates as the floor map drawing unit 114 and draws a floor map from the map data stored in the map data storage unit 122 according to the drawing floor floor stored in the determination result storage unit 124. It will be drawn and displayed on the display 105. In this way, the user can switch the floor map displayed in the display area 105A to the floor map one floor higher by enlarging the floor map until the ratio becomes smaller than the first threshold value threshold_1 using a pinch-out operation. can.

Furthermore, if it is determined in step S24 that the ratio b is not smaller than the first threshold threshold_1, the processor 101 determines whether the ratio b is greater than or equal to the second threshold threshold_2 and is a pinch-in operation (step S26). That is, the processor 101 determines that the ratio b is greater than or equal to the second threshold threshold_2 based on the second threshold threshold_2 of the drawing floor floor in the floor information table 121A, that is,
b ≧ threshold_2
In addition, it is determined whether the operation determined in step S21 is a pinch-in operation. If it is determined that the ratio b is not less than the second threshold threshold_2 and it is not a pinch-in operation, that is, if it is determined that the ratio b is not more than the second threshold threshold_2 or it is not a pinch-in operation, the processor 101 performs the steps in step S14 above. Move to processing.

On the other hand, if it is determined that the ratio b is greater than or equal to the second threshold threshold_2 and the pinch-in operation is performed, the processor 101 determines one floor below as the drawing floor (step S27). That is, the processor 101 stores a value obtained by adding "-1" to the value of the drawing floor floor stored in the judgment result holding section 124 in the judgment result holding section 124 as the new drawing floor value. After that, the processor 101 moves to the process of step S13 described above. Then, in step S13, the processor 101 operates as the floor map drawing unit 114 and draws a floor map from the map data stored in the map data storage unit 122 according to the drawing floor floor stored in the determination result storage unit 124. It will be drawn and displayed on the display 105. In this way, the user can switch the floor map displayed in the display area 105A to the floor map one floor below by reducing the floor map to a ratio equal to or higher than the second threshold value threshold_2 using a pinch-in operation.

As described in detail above, the multi-level map display device 1 according to the second embodiment of the present invention is a floor map display unit that displays a single-level floor map in the display area 105A of the display 105 in a facility having multiple levels.

Therefore, the user can intuitively and easily switch between floor maps of a multi-level facility.

In the multi-hierarchical map display device 1 according to the second embodiment, the detection target is a pinch-out operation or a pinch-in operation to enlarge or reduce the floor map displayed on the display unit, and the detection target is a pinch-out operation or a pinch-in operation to enlarge or reduce the floor map displayed on the display unit. The out/pinch-in determination unit 115 measures the amount of pinch-out or pinch-in operation, that is, the size of pinch-out/pinch-in, as the amount of displacement, and the display unit displays the pinch-out or pinch-in operation measured by the measurement unit. The floor map displayed on the display unit is enlarged or reduced according to the amount of the pinch-out operation or the pinch-in operation measured by the measurement unit. The hierarchy of the floor map displayed on the display section is changed according to the size of the portion of the floor map that is displayed on the display section.
Therefore, according to the second embodiment, the displayed floor map can be switched up or down depending on the size of the pinch-out/pinch-in, and the floor map can be moved up or down the floor smoothly from the flow of the scaling operation. Can be switched. Therefore, it is possible to realize an intuitive operation for the user.

In addition, the multi-hierarchical map display device 1 according to the second embodiment includes a floor information table storage unit 121 as a storage unit that stores the first threshold threshold_1 as a threshold for determining a change in the hierarchy of the floor map displayed on the display unit. Furthermore, the floor determination unit 113 as a control unit calculates the proportion of the entire floor map of the relevant floor occupied by the part of the floor map displayed in the display area 105A of the display unit, and determines that the calculated proportion is If it is smaller than the threshold value stored in the storage unit, the hierarchy of the floor map displayed on the display unit is changed to an upper floor.
Therefore, according to the second embodiment, when a pinch-out operation is performed, it is easy to determine whether the pinch-out operation is for a normal floor map enlargement instruction or a pinch-out operation for an instruction to change the display hierarchy. can be determined.

In addition, the multi-hierarchical map display device 1 according to the second embodiment further includes a storage unit that stores a second threshold threshold_2 as a threshold for determining a change in the hierarchy of the floor map displayed on the display unit.

Note that the direction of the drawing floor determined in step S25 and step S27 may be upside down.

[Third embodiment]
Furthermore, the user may be able to arbitrarily select the switching direction. This will be described below as a third embodiment. In the following description, parts similar to those in the second embodiment will be given the same reference numerals as those used in the second embodiment, and the description thereof will be omitted.

FIG. 11 is a block diagram showing an example of the functional configuration of a multi-hierarchical map display device 1 according to a third embodiment of the present invention. In the multi-hierarchical map display device 1 according to the present embodiment, in addition to the configuration in the second embodiment, the processing unit 11 includes a setting acquisition unit 116 as a processing function unit, and the storage unit 12 includes a setting holding unit 125. Equipped with

The setting acquisition unit 116 acquires, based on the user's operation of the touch panel 106, the setting of whether to switch the floor map displayed in the display area 105A to the upper or lower floor by using a pinch-out operation or a pinch-in operation, respectively. The settings acquisition unit 116 causes the settings storage unit 125 to store the acquired settings.

FIG. 12 is a diagram showing an example of the contents of this setting holding section 125. The setting holding unit 125 stores a transition destination, which is a switching direction, in correspondence with the direction of the pinch operation. In this example, the setting is such that a pinch-out operation switches to the floor map of the lower floor, and a pinch-in operation switches to the upper floor floor map.

Next, the processing operation of the multi-hierarchical map display device 1 configured as above will be explained.
FIG. 13 is a flowchart showing the operation processing procedure of the multi-hierarchical map display device according to the third embodiment. Here, the processes of steps S11 to S14, steps S21 to S24, and step S26 are as described in the second embodiment. However, if it is determined in step S21 that neither pinch-out nor pinch-in has been performed, in this embodiment, the processor 101 does not proceed to step S14, but proceeds to step S31. do.

That is, if it is determined that neither the pinch-out nor the pinch-in operation is performed in step S21, the processor 101 operates as the setting acquisition unit 116 and allows the user to perform a setting operation regarding the floor map switching direction using the touch panel 106. It is determined whether it has been done (step S31). If it is determined that no setting operation has been performed, the processor 101 moves to the process of step S14.

On the other hand, if it is determined that a setting operation has been performed, the processor 101 obtains the setting and stores the obtained setting in the setting holding unit 125 (step S32). After that, the processor 101 moves to the process of step S14 described above.

If it is determined in step S24 that the ratio b is smaller than the first threshold threshold_1, the processor 101 operating as the floor determining unit 113 adjusts the drawing floor according to the pinch-out setting stored in the setting holding unit 125. Determination is made (step S33). For example, if the settings stored in the setting holding unit 125 are such that when the pinch-out operation is performed, the setting is switched to the floor map of the lower floor, as shown in FIG. The value obtained by adding "-1" to the value of the drawing floor floor is stored in the determination result holding unit 124 as the new value of the drawing floor floor. After that, the processor 101 moves to the process of step S13 described above.

Further, if it is determined in step S26 that the ratio b is equal to or higher than the second threshold threshold_2 and that the pinch-in operation is performed, the processor 101 operating as the floor determination unit 113 draws the image according to the pinch-in settings stored in the setting storage unit 125. The floor is determined (step S34). For example, if the setting stored in the setting holding unit 125 is such that when a pinch-in operation is performed, the setting is switched to the floor map of the upper floor, as shown in FIG. The value obtained by adding "+1" to the value of the floor floor is stored in the determination result holding unit 124 as the new value of the drawing floor floor. After that, the processor 101 moves to the process of step S13 described above.

In this way, when the user instructs switching of the floor map displayed in the display area 105A by a pinch-out operation or a pinch-in operation, it is possible to switch to the set vertical floor map.

As described in detail above, the multi-hierarchical map display device 1 according to the third embodiment of the present invention has a storage unit that stores the first threshold value threshold_1 as a threshold value for determining a change in the hierarchy of the floor map displayed on the display unit. In addition to the floor information table storage unit 121, a setting acquisition unit 116 and a setting storage unit 125 serve as a change direction storage unit that receives a selection of the direction of change in the hierarchy of the floor map displayed on the display unit and stores the selection result. The floor determination unit 113 as a control unit calculates the ratio between the size of the floor map measured by the measurement unit and the size of the entire floor map of the floor, and stores the calculated ratio in the storage unit. If the floor map is smaller than the threshold value, it is determined whether to change to the upper or lower level of the floor map displayed on the display unit based on the selection result stored in the change direction storage unit.
Therefore, according to the third embodiment, it is possible to set whether to switch to the upper floor or lower floor floor map when a large pinch-out operation is performed.

Further, in the third embodiment of the present invention, in addition to the floor information table storage unit 121 as a storage unit that stores the second threshold threshold_2 as a threshold for determining a change in the hierarchy of the floor map displayed on the display unit, the display unit The floor determination unit 113 as a control unit further includes a setting acquisition unit 116 and a setting storage unit 125 as a change direction storage unit that receives a selection of a direction for changing the hierarchy of the floor map to be displayed and stores the selection result. , calculates the ratio between the size of the floor map measured by the measurement unit and the size of the entire floor map of the relevant floor, and when the calculated ratio is greater than or equal to the threshold stored in the storage unit, the change direction storage unit stores the ratio. Based on the stored selection results, it is determined whether to change the floor map to be displayed on the display unit above or below the hierarchy.
Therefore, according to the third embodiment, when a large pinch-in operation is performed, it is possible to set whether to switch to the upper or lower floor map.

[Fourth embodiment]
Next, a fourth embodiment of the invention will be described. In the second and third embodiments, the floor map was switched depending on the size of the pinch-out/pinch-in operation, but in the fourth embodiment, the floor map is switched depending on the speed of the pinch-out/pinch-in operation. This is an example of switching the floor map. In the following description, parts similar to those in the second embodiment will be given the same reference numerals as those used in the second embodiment, and the description thereof will be omitted. It goes without saying that this embodiment can also be modified so that the user can arbitrarily specify which direction to switch to, like the third embodiment.

The functional configuration of the multi-hierarchical map display device 1 according to the fourth embodiment is basically the same as that of the second embodiment shown in FIG. 6. However, in this embodiment, the pinch-out/pinch-in determination unit 115 has a function of acquiring the speed of the pinch-out operation or pinch-in operation in addition to the presence or absence of the pinch-in operation. That is, the pinch-out/pinch-in determination unit 115 determines whether it is a pinch-out operation or a pinch-in operation, depending on the movement direction of the user's two fingers, that is, whether the two fingers are moving away from each other or toward each other. Determine whether it is. Furthermore, the pinch-out/pinch-in determination unit 115 calculates the moving speed of the two fingers from the positions before and after the movement of the two fingers and the time taken for the movement, and uses this as the pinch-out/pinch-in speed. The pinch-out/pinch-in determining unit 115 stores the acquired pinch-out/pinch-in speed in the determination result holding unit 124.

Furthermore, in the multi-hierarchical map display device 1 according to the present embodiment, the contents of the floor information table for each facility stored in the floor information table storage unit 121 are different from those in the second embodiment. FIG. 14 is a diagram showing an example of the contents of one floor information table 121A stored in the floor information table storage unit 121 in this embodiment. The floor information table 121A is a table that describes a minimum altitude value altitude_min, a maximum altitude value altitude_max, and a threshold value threshold for each floor number. The minimum altitude value altitude_min and the maximum altitude value altitude_max are as described in the first embodiment. The threshold value threshold is a threshold value regarding the speed of pinch-out/pinch-in. Here, it is assumed that the threshold value threshold is the number of millimeters per second. That is, in the example of FIG. 14, the threshold value threshold is 50 mm/s on each floor.

Next, the processing operation of the multi-hierarchical map display device 1 configured as above will be explained.
FIG. 15 is a flowchart showing the operation processing procedure of the multi-hierarchical map display device according to the fourth embodiment. Here, the processes in steps S11 to S14 and step S21 are as described in the second embodiment.

If it is determined in step S21 that a pinch-out operation or a pinch-in operation has been performed, the processor 101 operating as the pinch-out/pinch-in determining unit 115 acquires the speed of the pinch-out/pinch-in and stores it in the determination result holding unit 124. It is stored (step S41). Then, as described in the second embodiment, the processor 101 operates as the floor map drawing unit 114 and updates the display (step S22).

Thereafter, the processor 101 operates as the floor determination unit 113 and determines whether the pinch-out/pinch-in speed is greater than the threshold (step S42). That is, the processor 101 reads the threshold value threshold of the drawing floor floor in the floor information table 121A of the current facility stored in the floor information table storage unit 121, which is indicated by the drawing floor floor stored in the determination result holding unit 124. Then, the processor 101 determines whether the pinch-out/pinch-in speed stored in the determination result holding unit 124 is greater than the read threshold threshold. If the processor 101 determines that the pinch-out/pinch-in speed is not greater than the threshold, the processor 101 moves to the process of step S14.

On the other hand, if it is determined that the pinch-out/pinch-in speed is greater than the threshold, the processor 101 determines the drawing floor depending on whether it was a pinch-out operation or a pinch-in operation (step S43). For example, in the case of a pinch-out operation, the processor 101 stores the determination result by adding “+1” to the value of the drawing floor floor stored in the determination result holding unit 124 as the new value of the drawing floor floor. The information is stored in the section 124. Further, in the case of a pinch-in operation, the processor 101 stores the determination result by adding "-1" to the value of the drawing floor stored in the determination result holding unit 124 as the new value of the drawing floor floor. The information is stored in the section 124. After that, the processor 101 moves to the process of step S13 described above.

Note that the direction of the drawing floor determined in step S43 may be upside down. Of course, as in the third embodiment, the user may be able to arbitrarily select the switching direction.

As described in detail above, the multi-hierarchical map display device 1 according to the fourth embodiment of the present invention is a floor map display unit that displays a single-level floor map in the display area 105A of the display 105 in a facility having multiple floors. A map drawing unit 114, a pinch-out/pinch-in determining unit 115 as a measuring unit that measures the speed of the pinch-out operation or pinch-in operation as the amount of physical displacement with respect to the detection target, and a It also includes a floor determination section 113 as a control section that changes the hierarchy of the floor map displayed on the display section.
Therefore, according to the multi-hierarchical map display device 1 according to the fourth embodiment, the hierarchy of the displayed floor map can be switched depending on the speed of the pinch-out operation or the pinch-in operation. Therefore, the user can intuitively and easily switch between floor maps of a multi-level facility.

The multi-hierarchical map display device 1 according to the fourth embodiment also includes a floor information table storage unit 121 as a storage unit that stores a speed threshold for a pinch-out operation or a pinch-in operation, and a floor determination unit 113 as a control unit. changes the hierarchy of the floor map displayed on the display unit when the speed of the pinch-out operation or pinch-in operation measured by the measurement unit is greater than the threshold value stored in the storage unit.
Therefore, according to the fourth embodiment, when a pinch-out/pinch-in operation is performed, it is determined whether the pinch-out/pinch-in operation is for a normal floor map enlargement/reduction instruction or the pinch-out/pinch-in operation for an instruction to change the display hierarchy. It is possible to easily determine whether it is a pinch-in operation.

Further, in the multi-hierarchical map display device 1 according to the fourth embodiment, the floor determination unit 113 as a control unit determines the floor map to be displayed on the display unit depending on whether the pinch-out operation or the pinch-in operation is performed. The hierarchy is updated either upward or downward.
Therefore, according to the fourth embodiment, the hierarchy can be switched in the opposite direction by the pinch-out operation and the pinch-in operation.

Further, the multi-hierarchical map display device 1 according to the fourth embodiment accepts a selection of a direction in which to change the hierarchy of a floor map displayed on the display unit by a pinch-out operation and the pinch-in operation, and stores the selection result in a change direction. It further includes a setting acquisition section 116 and a setting holding section 125 as a storage section, and the floor determination section 113 as a control section stores information stored in the change direction storage section when changing the hierarchy of the floor map displayed on the display section. Based on the selection result, it is determined whether to change to the upper or lower level of the floor map hierarchy to be displayed on the display unit.
Therefore, according to the fourth embodiment, it is possible to set whether to switch to the upper floor or lower floor floor map when a large pinch-out operation or pinch-in operation is performed.
