  Embodiments of the present invention will be described below with reference to the drawings.

<Embodiment 1>
First, the structure of the tactile sensation control system according to the first embodiment of the present invention will be described. In the present embodiment and the following embodiments, a case where the tactile sensation control system is realized by a single tactile sensation control device will be described.

  FIG. 1 is a block diagram illustrating an example of the configuration of the tactile sensation control device 1 according to the first embodiment. FIG. 1 shows the minimum necessary components constituting the tactile sensation control device 1.

  As shown in FIG. 1, the tactile sensation control device 1 includes at least a map information acquisition unit 2 and a tactile sensation control unit 3.

  The map information acquisition unit 2 acquires map information including features displayed corresponding to the operation surface of the touch panel or the touch pad.

  The tactile sensation control unit 3 controls the tactile sensation of the operation surface based on the map information acquired by the map information acquisition unit 2 so that the region of the operation surface corresponding to the feature becomes a tactile sensation according to the feature. . It should be noted that the features include realistic features and virtual features (for example, administrative division lines).

  Here, the tactile sensation controlled by the tactile sensation control unit 3 will be described with reference to FIGS.

  FIG. 2 is a diagram illustrating an example of three tactile sensations of “smooth”, “half-gritty”, and “gritty”.

  In FIG. 2, the horizontal axis indicates the strength of the tactile sensation, the leftmost column indicates “smooth”, the middle two columns indicate “half rough”, and the rightmost column indicates “gritty”. Yes. Further, the tactile sensation of the entire square is expressed by vibrating the dot or line pattern portion expressed in black shown in each square by, for example, ultrasonic vibration. That is, for example, when the intensity of vibration in each square is the same, the tactile sensation of “roughness” is stronger on the right side than on the left side in FIG. Specifically, the first line in FIG. 2 indicates that the larger the dot eyes, the stronger the feel of the grain. The second line indicates that the narrower the grid interval, the stronger the feel of the grain. The third line It shows that the feel of roughness increases as the line changes from a broken line to a solid line and the line becomes thicker. Note that the texture pattern of the rough texture is not particular to FIG. 2, and there are infinite combinations.

  The example in FIG. 2 shows a method for obtaining a different rough feel by changing the pattern even if the vibration intensity is the same. However, if the vibration intensity is changed even if the pattern is the same, A tactile sensation can be obtained.

  The “smooth” tactile sensation can be expressed, for example, by not performing ultrasonic vibration.

  The “gritty” tactile sensation can be expressed by, for example, performing ultrasonic vibration with a strength equal to or greater than a predetermined threshold.

  The “half-grainy” tactile sensation can be expressed, for example, by performing ultrasonic vibration that is smaller than the threshold value.

  Further, by combining both the strength of vibration and the rough tactile sensation pattern as shown in FIG. 2, the strength of the rough tactile sensation can be expressed.

  In FIG. 2, the rough texture pattern and the static rough texture that does not change the vibration intensity have been explained. However, the vibration intensity is changed with time, or the rough texture pattern is temporal. It is also possible to express the tactile sensation of moving by changing it to (ie, by dynamically changing the vibration pattern or the tactile pattern of the gritty tactile).

  3 to 5 are diagrams illustrating an example in which a “moving rough” tactile sensation is generated by temporally changing the intensity of vibration. 3 to 5, the horizontal axis represents time, and the vertical axis represents the strength of tactile sensation.

  FIG. 3 shows a case where the tactile sensation is constant and the tactile sensation occurs at a constant period. FIG. 4 shows a case where the tactile sensation is changed and the tactile sensation occurs at a constant cycle. FIG. 5 shows a case where the tactile sensation is constant and the tactile sensation cycle changes.

  By changing the tactile sensation as shown in FIGS. 3 to 5, for example, the user can obtain a tactile sensation as if the “gritty” area is moving (that is, the tactile sensation of “moving gritty”). In addition, in FIGS. 3 to 5, the feeling of “gritty” and the feeling of “smooth” are alternately switched, but the feeling of “gritty” and the feeling of “half-gritty” may be alternately switched. The texture of the “roughness” may be switched continuously instead of discretely, and a continuous change and a discrete change may be freely combined.

  FIG. 6 is a diagram illustrating another example of generating a “moving rough” tactile sensation by changing a rough tactile sensation pattern with time. In FIG. 6, the vertical axis indicates time. Moreover, the area | region a and the area | region b have a tactile feeling, for example.

  As shown in FIG. 6, the positions of the area a and the area b are moved with time. In this way, by moving the region a and the region b having a tactile sensation, the user can obtain a tactile sensation as if the “rough” region is moving (ie, a “moving rough” tactile sense). In addition, each of the area | region a and the area | region b may have a tactile sensation as shown in any of FIGS.

  Further, in FIG. 6, the “gritty” tactile sensation region and the “smooth” tactile sensation region are moved temporally, but the “gritty” tactile sensation region and the “half-gritty” tactile sensation region are It may be configured and moved in time, or an area in which the “gritty” tactile sensation changes discretely or continuously may be configured to move in time. In FIGS. 3 to 6, when a “gritty” tactile sensation that changes continuously is adopted, a smooth “growing gritty” tactile sensation can be obtained.

  Next, another configuration of the tactile sensation control device 1 including the map information acquisition unit 2 and the tactile sensation control unit 3 of FIG. 1 will be described.

  FIG. 7 is a block diagram illustrating an example of the configuration of the tactile sensation control device 4.

  As shown in FIG. 7, the tactile sensation control device 4 includes a map information acquisition unit 2, a tactile sensation control unit 3, a control unit 5, a display information generation output unit 6, an operation information acquisition unit 7, and a vehicle information acquisition unit. 8 and. The display information generation / output unit 6 is connected to a display 9, the tactile sensation control unit 3 and the operation information acquisition unit 7 are connected to a tactile touch panel 10, and the map information acquisition unit 2 is connected to a map DB (database) 11. Yes.

  The map information acquisition unit 2 acquires map information from the map DB 11.

  The control unit 5 controls the entire tactile sensation control device 4. In the example illustrated in FIG. 7, the control unit 5 controls the map information acquisition unit 2, the display information generation / output unit 6, the tactile sensation control unit 3, and the vehicle information acquisition unit 8.

  The display information generation / output unit 6 generates display information in accordance with instructions from the control unit 5. The display information generation / output unit 6 converts the generated display information into a video signal and outputs the video signal to the display unit 9.

  The tactile sensation control unit 3 controls the operation surface area of the tactile touch panel 10 corresponding to the feature to have a tactile sensation according to the feature based on the map information acquired by the map information acquisition unit 2. The tactile sensation control information is output to the tactile touch panel 10.

  The operation information acquisition unit 7 acquires information related to a user operation on the tactile touch panel 10 as operation information from the tactile touch panel 10.

  The vehicle information acquisition unit 8 is configured to detect sensor information (such as vehicle speed pulse information) detected by various sensors provided in the vehicle, vehicle control information, or GPS (Global Positioning System) via an in-vehicle LAN (Local Area Network). ) Get information etc. as vehicle information.

  The display 9 displays the display information input from the display information generation / output unit 6 on the display screen.

  The tactile touch panel 10 outputs information related to the touch operation by the user (information such as presence / absence of touch, position of touch, operation content) to the operation information acquisition unit 7 as operation information. The tactile touch panel 10 changes the tactile sensation (“smooth”, “half-gritty”, “gritty”, “moving gritty”) at any position on the touch panel based on the haptic control information input from the haptic control unit 3. Let

  The tactile touch panel 10 is provided on the display screen of the display device 9, and the user can use the touch panel 10 with a sense of directly operating the display screen. That is, the display screen area of the display unit 9 and the area where the tactile sensation touch panel 10 is generated may completely coincide. In addition, one of the display screen area of the display 9 and the area that generates the tactile sensation of the tactile touch panel 10 may be an area wider than the other. For example, the tactile touch panel 10 is installed so that the area where the tactile sensation of the tactile touch panel 10 is generated protrudes from the display screen area of the display unit 9 and is used as an area where touch operation can be input although not displayed in the extended area. Also good.

  The map DB 11 stores map information including features. The map DB 11 may be provided in the vehicle or provided outside.

  Next, the operation of the tactile sensation control device 4 will be described.

  FIG. 8 is a flowchart showing an example of the operation of the tactile sensation control device 4.

  In step S11, the map information acquisition unit 2 acquires map information from the map DB 11.

  In step S <b> 12, the display information generation / output unit 6 generates map information as display information in accordance with an instruction from the control unit 5, converts the generated map information into a video signal, and outputs the video signal to the display unit 9.

  In step S <b> 13, the tactile sensation control unit 3 sets tactile sensation control information for each feature according to an instruction from the control unit 5.

  In step S14, the tactile sensation control unit 3 outputs the tactile sensation control information set in step S13 to the tactile touch panel 10. In the tactile sensation touch panel 10, a different tactile sensation is generated for each feature based on the tactile sensation control information input from the tactile sensation control unit 3.

  Next, a specific operation example of the tactile sensation control device 4 will be described with reference to FIGS. 9 and 10.

  In FIG. 9, a map is displayed on the display screen of the display device 9. In the tactile touch panel 10, the tactile sensation is different for each feature. Specifically, the tactile sensation in the area of the vehicle position 12 is “gritty”, the tactile sensation in the road 13 is “gritty”, the tactile sensation in the mountainous area 14 is “gritty”, and the tactile sensation in the sea 15 (water system) area. Is a “moving rough” that mimics the movement of water, the touch of the area of the flat land 16 is “half rough”, and the touch of the area of the city area 17 is “smooth”. In this way, the user can easily identify each feature by making the feel different for each feature.

  The city district 17 may include information on the city district 17 in the map information stored in the map DB 11, and the number of POIs (Point Of Interest) per unit area is equal to or greater than a predetermined number. This place may be the city district 17.

  In FIG. 9, the tactile sensation may be different for each type of POI. In addition, the desired POI tactile sensation selected by the user may be different from the other POI tactile sensations.

  In FIG. 9, you may give a tactile sensation to the administrative division line.

  FIG. 10 shows an example in which the tactile sensation is varied depending on the terrain. In FIG. 10, a map is displayed on the display screen of the display device 9. In the tactile touch panel 10, the tactile sensation is different for each feature. Specifically, the tactile sensation of the area of the host vehicle position 12 is “gritty”, the tactile sensation of the road 13 and its surrounding area is “smooth”, and the tactile sensation of the reachable area 19 that can be reached by a vehicle or a pedestrian is “smooth”. The tactile sensation of the reachable area 20 that can be reached by at least a pedestrian is “half rough”, the tactile sensation of the unreachable area 18 that cannot be reached by the vehicle or pedestrian is “gritty”, and the tactile sensation of the area of the sea 15 is “moving” It is “gritty”. The road 13 and the surrounding area are included in the reachable area 19. That is, the region where the tactile sensation is “smooth” or “half-grainy” indicates a region that can be reached by the vehicle or pedestrian, and the tactile sensation is “gritty” or “moving gritty” (excluding the own vehicle position 12). Indicates an area that cannot be reached by a vehicle or a pedestrian. In this way, by making the tactile sensation different for each terrain (that is, making the tactile sensation different between reachable areas and unreachable areas), the user can easily determine reachable or unreachable areas on the map. I can grasp it.

  From the above, according to the first embodiment, since the tactile sensation is different for each feature, the user can easily grasp the feature on the map without concentrating the line of sight on the display screen at the time of operation. Can do. That is, an operation that is convenient for the user can be performed.

  Each tactile sensation described above may be combined with other tactile sensations as appropriate. Further, the mountain portion 14 shown in FIG. 9 may have a physically raised shape as disclosed in Patent Document 3.

  In the first embodiment, the case where the tactile sensation control device 4 is mounted on a vehicle has been described as an example. However, the above-described function described in the first embodiment may be realized in a smartphone. For example, in FIG. 7, the vehicle information acquisition unit 8 is a smartphone information acquisition unit, the vehicle information is replaced with smartphone information, and the GPS information and acceleration sensor information built in the smartphone are input. Can be realized. In the case of a smartphone, since it is assumed that the user operates while walking, the effect of preventing a reduction in attention to the surroundings is obtained in such a case.

  In the first embodiment, the case where the tactile touch panel 10 is used has been described. However, as shown in FIG. 11, the indicator 9 is provided on the meter panel 21, and the tactile touch pad 22 is used instead of the tactile touch panel 10. (Ie, the display device 9 and the tactile touch pad 22 are separately installed at different locations) may be applied to a tactile control system for a meter panel. In the example of FIG. 11, the meter panel 21 is provided with a display 9 and a speedometer 23. When the display unit 9 is provided on the meter panel 21, the display unit 9 and the tactile touch pad 22 are separated from each other, so that an effect of largely preventing a reduction in the attention of the driver during operation can be obtained. The display device 9 provided in the meter panel 21 may use a partial region or the entire region of the meter panel 21 as a display region of the display device 9. In addition, the size of the region where the tactile sensation occurs on the tactile touch pad 22 and the size of the display region on the display 9 may be the same, may be similar, or may not be similar.

<Embodiment 2>
In the second embodiment of the present invention, a case will be described in which a tactile sensation is given to a region corresponding to a feature that is not displayed at the current map scale (a feature that is not displayed when the map scale is reduced). Since the configuration of the tactile sensation control apparatus according to the second embodiment is the same as that of the tactile sensation control apparatus 4 (see FIG. 7) according to the first embodiment, description thereof is omitted here.

  FIG. 12 is a diagram illustrating an example of the operation of the tactile sensation control apparatus according to the second embodiment.

  In FIG. 12, the vehicle position 12, the road 13, and the river 24 are displayed on the map on the display screen of the display device 9. It is assumed that the road 25 is not displayed at the scale shown in FIG.

  In the tactile touch panel 10, the tactile sensation of the area of the river 24 is “gritty”, and the tactile sensation of the area where the road 25 exists in the river 24 (area where the road 25 passes the river) is “smooth”. ing. Further, the tactile sensation in the area other than the river 24 is “half rough”. In this way, by making the tactile sensation of a part of the river 24 where the road 25 intersects different from the tactile sensation of the other area of the river 24, the user can cross although not displayed on the map. It can be easily grasped.

  In addition, although the case where the tactile sensation of a part of the river 24 is “smooth” is described in FIG. 12, the tactile sensation of a part of the road 25 (a region crossing the river 24) may be “smooth”.

  Although the case where the road 25 crossing the river 24 exists has been described in FIG. 12, the present invention is not limited to this. For example, even when there is a road crossing the track, the tactile sensation can be controlled in the same manner as described above.

  FIG. 13 is a diagram illustrating another example of the operation of the tactile sensation control apparatus according to the second embodiment.

  In FIG. 13, the vehicle position 12, the road 13, and the rivers 24 and 26 are displayed on the map on the display screen of the display 9. Note that the river 26 is a tributary of the river 24 and is not displayed when the scale is reduced as shown in the right diagram of FIG. 13 (in the right diagram of FIG. 13, it is indicated by a broken line for convenience). In the tactile touch panel 10, the tactile sensation in the areas of the rivers 24 and 26 is “moving rough”, and the tactile sensation in the areas other than the rivers 24 and 26 is “smooth”.

  When the scale is changed from the left diagram to the right diagram in FIG. 13, the river 26 is not displayed on the map, but the feel of the area of the river 26 is “moving rough”. Thus, even if there is a feature that is not displayed on the map with a reduced scale, the user can easily grasp the position of the feature on the map by leaving the tactile sensation.

  In FIG. 13, the river has been described as an example of the feature. However, the present invention is not limited to this, and may be applied to, for example, POI. In this case, for example, when the user is searching for a desired facility, the tactile sensation of the facility area may be “gritty”, and at the same time, a mark indicating the facility may be displayed.

  In particular, when the scale is wide, when a POI is displayed on the display screen, there is too much POI and it is very difficult to see, so a screen that does not display the POI is generated. It is possible to recognize the presence of a desired POI by simply tracing the screen, and an excellent user interface can be realized.

  From the above, according to the second embodiment, it is easy to see the map after changing the scale by giving a tactile sensation to the area of the feature that is not displayed at the scale of the current map. The position of the feature can be easily grasped. That is, an operation that is convenient for the user can be performed.

  Each tactile sensation described above may be combined with other tactile sensations as appropriate.

<Embodiment 3>
In the third embodiment of the present invention, a case will be described in which the tactile sensation between the route from the current position to the destination differs from the road other than the route. Since the configuration of the tactile sensation control apparatus according to the third embodiment is the same as that of the tactile sensation control apparatus 4 (see FIG. 7) according to the first embodiment, the description thereof is omitted here. It is assumed that the tactile sensation control device according to the third embodiment has a navigation function. For example, the control unit 5 may have the navigation function.

  FIG. 14 is a diagram illustrating an example of the operation of the tactile sensation control apparatus according to the third embodiment.

  In FIG. 14, the display screen of the display 9 displays on the map the vehicle position 12, the road 13, and the route 27 from the current position (vehicle position 12) to the destination. In the tactile touch panel 10, the tactile sensation in the region of the route 27 is “moving rough”, and the tactile sensation in the region of the road 13 is “gritty”.

  From the above, according to the third embodiment, the user can change the route by making the feel of the area of the route 27 from the current position (vehicle position 12) to the destination different from the area of the other roads. It can be easily grasped. That is, an operation that is convenient for the user can be performed.

  In FIG. 14, the moving speed of the “moving rough” path 27 may be changed according to the speed of the vehicle. By doing in this way, the user can grasp | ascertain the speed of a vehicle by tactile sensation.

  In FIG. 14, when the user touches the road 13 and the route 27, a tactile sensation may be given to the region of the road 13 and the region of the route 27. By doing in this way, it can contribute to energy saving.

<Embodiment 4>
In the fourth embodiment of the present invention, a case will be described in which the tactile sensation of a feature is controlled based on information acquired from the outside.

  FIG. 15 is a block diagram showing an example of the configuration of the tactile sensation control device 28 according to the fourth embodiment.

  As shown in FIG. 15, the tactile sensation control device 28 includes a communication unit 29. Other configurations are the same as those of the first embodiment (see FIG. 7), and thus the description thereof is omitted here.

  The communication unit 29 is communicably connected to a communication terminal (not shown), and acquires various information from the outside.

  Next, the operation of the tactile sensation control device 28 will be described.

  As an example, when the communication unit 29 acquires information on road conditions, the tactile touch panel 10 is configured such that, for example, the tactile sensation of a road area where each vehicle is traveling without traffic jams is “moving rough”, and a road where traffic jams are occurring. The tactile sensation of the section area may be “gritty”, and the tactile sensation of the road area where road construction is being performed may be “gritty”. By doing in this way, the user can grasp | ascertain easily the traffic condition of a road with a tactile sensation.

  You may make it change the moving speed of said "moving rough" according to the average speed (traffic condition) of each other vehicle which drive | works the said road. In this case, the communication unit 29 acquires speed information (information on traffic conditions) from each of the other vehicles. The moving speed of the “moving rough” may be changed with the legal speed as a maximum value and the average speed as a reference with a predetermined threshold. By doing in this way, the user can grasp | ascertain easily the average speed of the vehicle which drive | works a road with a tactile sensation.

  As another example, when the communication unit 29 acquires the weather information, the tactile touch panel 10 has, for example, “smooth” for a tactile feeling in a sunny area, “moving rough” for a tactile area in a rainy area, The tactile sensation may be “half rough”, and the tactile sensation in snow or a frozen area may be “gritty”. In addition, you may provide said tactile sensation for every area surrounded by administrative division lines. By doing in this way, the user can grasp | ascertain the weather for every area easily by touch.

  As another example, when the communication unit 29 acquires information about the tide level, the tactile touch panel 10 changes the position of the tactile sensation corresponding to the change of the position of the shoreline. Here, it is assumed that the information on the tide level includes information on the time, atmospheric pressure, and the position of the shoreline due to the spring tide. By doing in this way, the user can grasp | ascertain the position of a shoreline easily by tactile sense.

  In addition, changes in features due to heavy rain, flood damage, or earth and sand disasters can be grasped by changing the tactile sensation, and an excellent user interface can be realized. In particular, in the case of a wide scale display, the user can recognize a place that hinders traffic by simply tracing the tactile touch panel 10 or the tactile touch pad.

  In addition, in the case of a smartphone, it becomes easy to recognize places that cannot be reached by stopping transportation, closing facilities, or walking.

  As described above, according to the fourth embodiment, since the tactile sensation is changed for each feature based on information acquired from the outside, the user does not concentrate the line of sight on the display screen during operation. The feature can be easily grasped. That is, an operation that is convenient for the user can be performed.

<Embodiment 5>
In the fifth embodiment of the present invention, a case where the user performs a scroll operation by dragging on the map will be described. The configuration of the tactile sensation control apparatus according to the fifth embodiment is the same as that of the tactile sensation control apparatus 4 according to the first embodiment (see FIG. 7) or the tactile sensation control apparatus 28 according to the fourth embodiment (see FIG. 15). Description is omitted.

  The tactile sensation control unit 3 controls the tactile sensation of the user's touch position to change when a predetermined feature exists on the map in the scroll direction. Here, the predetermined feature may be a facility desired by the user, and may be a POI, a road including an expressway, an arbitrary point, or the like.

  FIG. 16 is a flowchart showing an example of the operation of the tactile sensation control apparatus according to the fifth embodiment. Note that steps S21 to S24 in FIG. 16 correspond to steps S11 to S14 in FIG.

  In step S <b> 25, the control unit 5 determines whether the user has performed a scroll operation on the tactile touch panel 10 via the operation information acquisition unit 7.
