Description

  The present invention relates to a navigation belt, a navigation system, and a program, and more particularly, to a technique for performing route guidance to a destination.

  In recent years, GPS has been installed in mobile phones and smartphones, and services that use a user's current location information to navigate to a destination have become widespread. However, since these navigation services display a map and route information on the screen of the mobile terminal, an action called “walking smartphone” where the user walks while looking at the screen of the mobile terminal is likely to cause an accident, which is a problem. Yes.

  On the other hand, Patent Document 1 discloses a navigation system that notifies a user of a traveling direction by giving a stimulus to a user with a vibration actuator. As a result, information useful for reaching the destination can be obtained without checking the display screen of the terminal.

  However, in the system of Patent Document 1, since the user himself / herself determines the direction to proceed, there is a problem that the user makes a determination mistakenly with respect to the notification by the stimulus (for example, “Left” is notified) Despite this, I accidentally move right). In other words, a certain amount of training is required in order to definitely move in the right direction using the system of Patent Document 1.

The means for pushing out the pressing portion 41 is not limited to a linear actuator. Any means that pushes the pressing portion 41 toward the inside of the navigation belt 3 may be used.

  FIG. 6 is a diagram illustrating a hardware configuration of the information terminal 5. As information terminal 5, portable information terminals, such as a smart phone and a tablet terminal, are employable. As shown in the figure, the information terminal 5 includes a control unit 51, a storage unit 52, a communication control unit 53, an input unit 54, a display unit 55, a peripheral device I / F unit 56, a position acquisition unit 57, etc. Connected and configured. The configurations of the control unit 51, the storage unit 52, the communication control unit 53, the peripheral device I / F unit 56, and the position acquisition unit 57 are substantially the same as the configuration of the control device 30 in FIG.

  The input unit 54 includes an input device such as a touch panel, for example. The user inputs a route guidance destination via the input unit 54.

  The display unit 55 includes a display device such as a liquid crystal panel, and a logic circuit (such as a video adapter) for realizing the video function of the information terminal 5 in cooperation with the display device. The input unit 54 and the display unit 55 may be integrated like a touch panel display.

Map information is stored in the storage unit 52 of the information terminal 5 or the storage unit 32 of the control device 30. The map information includes node information that holds map images and information (including position information) of each point (node) set on the map, and information on the route (link) that connects each node (route travel distance) And link information that holds information such as travel time).
In addition, a program (route generation program) for generating a route on the map from the current location to the destination is installed in the storage unit 52 of the information terminal 5 or the storage unit 32 of the control device 30. The control unit 51 of the information terminal 5 or the control unit 31 of the control device 30 activates this route generation program, searches for the shortest route on the map from the current location to the destination, and automatically generates a route. The search for the shortest path is executed using a known algorithm such as the Dijkstra method based on the node information and the link information. However, the present invention is not limited to this, and the route from the current location to the destination may be determined freely by the user and set manually.

  Further, a server (such as a cloud server) connected to the information terminal 5 or the control device 30 via a network stores the map information and the route generation program, and the current location and destination information transmitted from the information terminal 5 or the control device 30 is stored in the information. Based on this, a route may be generated. In this case, the server transmits the generated route information to the information terminal 5 or the control device 30, and is stored in the storage unit 52 of the information terminal 5 or the storage unit 32 of the control device 30.

  Subsequently, a route guidance process by the navigation system 1 using the navigation belt 3 will be described with reference to FIGS. It is assumed that the user holds the information terminal 5 and the navigation belt 3 is already attached to the trunk (for example, the waist).

FIG. 7 is a flowchart for explaining the overall flow of the route guidance process.
First, the information terminal 5 receives and sets an input of a route guidance destination from the user (step S1). Then, the shortest route from the current location (starting location) acquired from the position acquisition unit 57 to the destination set in step S1 is searched, and a route is generated (step S2). As described above, the route may be determined freely by the user and set manually. Alternatively, the route may be generated by a server connected to the information terminal 5 via a network. In this case, the information terminal 5 transmits the current location and destination information to the server, and the server generates a route based on the received current location and destination information. The information terminal 5 receives the generated route information from the server and stores it in the storage unit 52.

  FIG. 9A shows an example of the route R generated in step S2. In the example shown in the figure, a route R connecting node N0 (departure point) → node N1 → node N2 → node N3 → node N4 → node N5 (destination) is generated as a route from the current location (departure location) to the destination. ing.

  FIG. 9B shows an example of the data contents of the route information 60 that holds the generated route R information. The node ID 61 is information for uniquely identifying each node constituting the route R. The position information 62 is position information (for example, latitude / longitude information) that specifies the position of each node. The direction change information 63 is information on the direction in which the direction is changed, which is set only when the direction change is necessary. For example, at node N2, the user needs to change the direction of travel to the right. Therefore, “right” is set in the direction change information 63 of the node ID (“N2”). Further, at the node N3, the user needs to change the traveling direction to the left. Therefore, “left” is set in the direction change information 63 of the node ID (“N3”). “−” Is set in the direction change information 63 of the node that does not need to change direction.

  Subsequently, the information terminal 5 acquires the current position of the user by the position acquisition unit 57 (GPS sensor or the like) (step S3). Then, referring to the acquired current position and route information 60, it is determined whether or not the user has reached the destination (step S4). For example, when the distance difference between the position of the destination of the route information 60 (node N5 in the example of FIG. 9) and the current position is equal to or smaller than a preset threshold, the control device 30 determines that the user has reached the destination. to decide. If the destination is reached (step S4; Yes), the route guidance is terminated.

  If the destination has not been reached (step S4; No), the information terminal 5 determines whether it is time for the user to change direction (step S5). Specifically, referring to the route information 60, it is determined whether or not the next point (node) viewed from the current location is a point that needs to change direction (hereinafter also referred to as “direction changing point”). If the point (node) is a turning point, whether or not it is time to change direction taking into account the “arrival distance” from the current location to the turning point and the “arrival time” from the current location to the turning point Determine whether.

  For example, in FIG. 10 (a diagram showing how the user moves along the route R), a predetermined range centered on the nodes N2 and N3, which are points (nodes) that require a direction change (for example, centering on the direction change point). An area having a radius of 10 m is defined as a direction change area (direction change area A1, A2) in which the direction is changed. And if the present position acquired by the position acquisition part 57 enters in this direction change area, it will be judged as the timing which changes direction. This is an example of determining the timing for changing the direction in consideration of the “arrival distance” from the current location to the turning point.

  Alternatively, the arrival time to the turning point is calculated based on the current position and moving speed (traveling speed) of the user acquired by the position acquisition unit 57, and the arrival time to the turning point is less than a predetermined time (for example, 3 seconds) The following may be determined as the timing for changing the direction. This is an example of determining the timing for changing the direction in consideration of the “arrival time” from the current location to the turning point.

  If it is determined that it is not time to change direction (step S5; No), the process returns to step S3. On the other hand, when it is determined that the timing for changing the direction is reached (step S5; Yes), the information terminal 5 sets the direction for changing the direction as the user's traveling direction (the direction in which the user travels), and the traveling direction ("right"). Alternatively, the driving command corresponding to “left”) is transmitted to the navigation belt 3 (control device 30), and the navigation belt 3 (control device 30) that has received this driving command receives the driving command in the traveling direction based on the driving command. The pressing control by the pressing device 40 is executed so as to rotate the body (step S6).

FIG. 8 is a flowchart for explaining the pressing control process in step S6.
When the direction in which the direction is changed (the user's traveling direction) is “right” (step S21 “right”), the control device 30 transmits a drive command to the left front pressing device 40c and the right rear pressing device 40d. The left front pressing device 40c and the right rear pressing device 40d that have received the drive command drive each pressing portion 41 (41c, 41d) and press the user's body (body C, body D in FIG. 4). (Step S22).

  For example, in FIG. 10, when the current location of the user is the position P2 (when the next advancing direction is “right”), the user's torso is formed by the pressing portions 41 (41c, 41d) of the left front pressing device 40c and the right rear pressing device 40d. The parts (the body part C and the body part D in FIG. 4) are pressed. As a result, the user's body is reflexively rotated in the right direction, which is the direction in which the user proceeds, according to the hanger reflection principle.

  On the other hand, when the direction in which the direction is changed (the user's traveling direction) is “left” (step S21 “left”), the control device 30 transmits a drive command to the right front pressing device 40a and the left rear pressing device 40b. . The right front pressing device 40a and the left rear pressing device 40b that have received the drive command drive the pressing portions 41 (41a and 41b) and press the user's trunk portions (the trunk portion A and the trunk portion B in FIG. 3). (Step S23).

  For example, in FIG. 10, when the current location of the user is the position P4 (when the next advancing direction is “left”), the user's torso is formed by the pressing portions 41 (41a, 41b) of the right front pressing device 40a and the left rear pressing device 40b. The parts (the body part A and the body part B in FIG. 3) are pressed. As a result, the user's body is reflexively rotated in the left direction, which is the direction in which the user proceeds, by the principle of hanger reflection.

  Subsequently, the information terminal 5 determines whether or not the user has finished turning (step S24). For example, in FIG. 10, when the user moves out of the direction change areas A1 and A2 of the nodes N2 and N3 that are the direction change points (when the user moves to the positions P3 and P5), it is determined that the user has finished the direction change. Alternatively, when the direction in which the user is currently acquired and the direction in which the user is traveling (the direction of the path R) acquired by the position acquisition unit 57 (acceleration sensor, gyro sensor, geomagnetic sensor, etc.) matches, the user changes the direction. You may judge that it was finished.

  When the direction change is not completed (during the direction change) (step S24; No), the pressing of the user's body by the pressing device 40 (the pressing unit 41) is continuously performed. On the other hand, if it is determined that the user's direction change has ended (step S24; Yes), the information terminal 5 transmits a stop command to the pressing device 40 via the control device 30, and the pressing device 40 that has received the stop command. After the pressing part 41 is returned to the initial position (the body part of the user is not pressed), the driving is stopped (step S25).

  As described above, the navigation belt 3 of the present invention drives each pressing device 40 in accordance with the direction in which the user travels, presses (squeezes) the user's torso, and travels along the user's body based on the hanger reflection principle. Let it turn to nature. In the conventional navigation system that notifies the direction of travel, even if the notified information is received, there is a possibility that the user may proceed in the wrong direction by mistake. According to the navigation belt 3 of the present invention, the user's body is naturally directed in the direction of traveling according to the principle of hanger reflection, so that the user can be guided to the correct route without any mistake without the user's judgment.

  Note that the configuration of the control device 30 may be omitted from the navigation belt 3 by providing the information terminal 5 with all the functions of the control device 30. In this case, the pressing device 40 includes a communication control unit, so that the information terminal 5 and the pressing device 40 are connected wirelessly or by wire, and data such as a drive command is exchanged between the information terminal 5 and the pressing device 40. Done. The pressing device 40 includes a pressing control unit that performs pressing control based on a drive command. In the case of such a system configuration, the process in step S6 in FIG. 7 and the process in FIG. 8 are as follows. That is, in step S6 of FIG. 7, the information terminal 5 transmits a drive command corresponding to the traveling direction (“right” or “left”) to the pressing device 40 via the communication control unit. Based on the drive command, the pressing control of FIG. 8 is executed. Specifically, when the direction in which the direction is changed (the user's traveling direction) is “right” (step S21 “right” in FIG. 8), the information terminal 5 sends the left front pressing device via the communication control unit. A drive command is transmitted to 40c and the right rear pressing device 40d. The left front pressing device 40c and the right rear pressing device 40d that have received the drive command drive each pressing portion 41 (41c, 41d) and press the user's body (body C, body D in FIG. 4). (Step S22 in FIG. 8). On the other hand, when the direction in which the direction is changed (the user's traveling direction) is “left” (step S21 “left” in FIG. 8), the information terminal 5 and the right front pressing device 40a are connected to the left via the communication control unit. A drive command is transmitted to the backward pressing device 40b. The right front pressing device 40a and the left rear pressing device 40b that have received the drive command drive the pressing portions 41 (41a and 41b) and press the user's trunk portions (the trunk portion A and the trunk portion B in FIG. 3). (Step S23 in FIG. 8). In step S25 of FIG. 8, the information terminal 5 transmits a stop command to the driving pressing device 40 via the communication control unit, and the pressing device 40 that has received the stop command sets the pressing unit 41 to the initial position. After returning, the driving is stopped (the user's body is not pressed).

  Alternatively, the configuration of the information terminal 5 may be omitted from the navigation system 1 by providing the control device 30 with all the functions of the information terminal 5. In this case, the control device 30 executes all the processes in FIG. That is, the control device 30 sets a destination (step S1), and generates a route from the current location to the destination (step S2). When the control device 30 acquires the current position (step S3), the control device 30 determines whether the destination has been reached (step S4), determines whether the direction change is necessary (step S5), and the direction change is necessary. In this case, a driving command corresponding to the direction of change of direction (“right” or “left”) is transmitted to the pressing device 40 to perform pressing control (step S6).

[Second Embodiment]
FIG. 11 is a diagram showing a navigation belt 3A according to the second embodiment.
Unlike the first embodiment, the navigation belt 3A can be worn on the user's head. Unlike the first embodiment, the control device 300 for the navigation belt 3A includes a display unit 306 (see FIG. 12). That is, the navigation belt 3A also functions as a head mounted display.

  Among these, the right front pressing device 400a and the left rear pressing device 400b are pressing devices for rotating the head of the user wearing the navigation belt 3 in the right direction using the principle of hanger reflection. Specifically, the pressing portions 410 (410a, 410b) of the right front pressing device 400a and the left rear pressing device 400b are pushed inward of the navigation belt 3 by a linear actuator (not shown), and the pressing portions 410a, 410b. The user's head region (right front head, left rear head) corresponding to the position is pressed (squeezed). As a result, hanger reflection occurs and the head rotates reflectively in the right direction.

Further, the left front pressing device 400c and the right rear pressing device 400d are pressing devices for rotating the head of the user wearing the navigation belt 3A in the left direction using the principle of hanger reflection. Specifically, each pressing portion 410 (410c, 410d) of the left front pressing device 400c and the right rear pressing device 400d is pushed inward of the navigation belt 3A by a linear actuator (not shown), and the pressing portions 410c, 410d. The user's head region (left front head, right rear head) corresponding to the position is pressed (squeezed). As a result, hanger reflection occurs and the head rotates reflectively in the left direction.
The means for pushing out the pressing portion 410 is not limited to a linear actuator. Any means may be used as long as it pushes the pressing portion 410 toward the inside of the navigation belt 3A.

  FIG. 12 is a diagram illustrating a hardware configuration of the control device 300 and the pressing device 400 constituting the navigation belt 3A. In the second embodiment, the control device 300 includes a display unit 306. Other configurations are substantially the same as those of the first embodiment. In addition, you may provide the headphone, the microphone, etc. which are not shown in figure.

  The display unit 306 is, for example, a transmissive display, has a glasses-like shape, and can display map information in the visual field region while allowing the user to visually recognize the outside world. For example, a map image, an image displaying a route on the map, an image displaying the current position along with the route on the map, information on guide points (intersections, convenience stores,...) Serving as landmarks in the route, and a direction to change direction. Display information clearly indicated by an arrow image.

  The basic processing of route guidance is substantially the same as the route guidance processing (FIGS. 7 and 8) of the first embodiment, and thus description thereof is omitted. However, in the second embodiment, arbitrary timing during route guidance is used. Thus, the map information as described above can be displayed on the display unit 306.

  Similarly to the first embodiment, the process of FIG. 7 may be executed in a shared manner with the information terminal 5 separately owned by the user, the configuration of the information terminal 5 is omitted, and the navigation belt 3A (control device 300). May be configured to execute the entire process.
