(First embodiment)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.

  FIG. 1 is a conceptual diagram showing a portable information communication system 500 according to the present embodiment. In the mobile information communication system 500 shown in FIG. 1, a mobile phone (mobile information communication terminal) 100 and a location information server (external server) 200 are communicatively connected via a mobile phone network 300.

  FIG. 2 is a functional block diagram showing functions of the mobile phone 100 shown in FIG. The mobile phone 100 in FIG. 2 inputs information indicating the departure place of the user who has the mobile phone 100 (hereinafter referred to as departure place information) and information indicating the destination (hereinafter referred to as destination information). Is received by the information input receiving unit 110, the current position positioning unit 140 that measures the current position of the mobile phone 100 at predetermined time intervals, and acquires the current position information of the current position, and the information input receiving unit 110. When the deviation distance between the travel route created based on the starting point information and the destination information and the current position measured by the current position positioning unit 140 is equal to or larger than the first threshold value, it is audible or tactile. And a notification unit 160 that performs a first notification output.

  Here, the departure point information (information indicating the departure point) means a point that is a starting point when the user aims at the destination along the movement route. Specifically, it may be an arbitrary place such as a station name, a place name specified on a map, or a building. Also, as will be described later, the current location can be set as the starting point.

  The destination information (information indicating the destination) means a point that is an end point that the user finally reaches along the movement route. This may be an arbitrary place such as a station name, a place name specified on a map, a building, etc. as in the departure place information.

  The current position means a point where the user is currently located, and the point where the mobile phone 100 is located is the current position of the user.

  The travel route is a travel route created from departure point information and destination information. This movement route is created in either the mobile phone 100 or the location information server 200. In the present embodiment, mobile phone 100 sets the created travel route in its own device, and guides the user from the travel route to the destination.

  Further, the divergence distance means a distance between the created movement route and the current position of the user. This divergence distance is calculated in order to confirm that the current position of the user is along the movement path, and depends on whether this divergence distance is less than the first threshold or greater than the first threshold. It is determined whether or not the vehicle is along the movement route.

  Further, as the first threshold value, for example, a distance such as 50 m or 100 m that is not determined to be off the route can be defined. By setting the first threshold value to a constant value without being excessively small, an allowable range can be generated even if the opposite sidewalk is walked across the road.

  In addition, when the notification unit 160 determines that the current position measured by the current position positioning unit 140 belongs within a predetermined reach from the destination, the notification unit 160 outputs a second notification output different from the first notification output. May be performed.

  Here, within the reach distance can be defined as a range that can objectively recognize the arrival at the destination. In this case, for example, when the vehicle arrives within a radius of 100 m from the destination, it can be determined that it belongs within the reach distance. When the destination is a station, a range indicating arrival at the station itself including the platform and the ticket gate may be determined based on the reach distance.

  Here, calculating the divergence distance not only calculates the distance between the current position information and the path information, but also determines the divergence distance between the current position and the movement path with the first threshold value by various data processing. Including that.

  In the present embodiment, the movement route is configured by route information. This may be, for example, a public institution such as a railroad, train or bus, or a road that forms a main road.

  In this embodiment, for example, a travel route creation program for creating a travel route is stored in the ROM 202. The CPU 201 can realize a function of creating a movement route by reading a movement route creation program from the ROM 202 into the RAM 203 and executing it in the RAM 203.

  Moreover, the various components in this Embodiment should just be formed so that the function may be implement | achieved. For example, it is realized as dedicated hardware that exhibits a predetermined function, a mobile phone provided with a predetermined function by a computer program, a predetermined function realized in a mobile phone by a computer program, or any combination thereof. be able to.

  Further, the various components of the present embodiment do not need to be individually independent. That is, a plurality of components are formed as one device, one component is formed of a plurality of devices, a certain component is a part of another component, a certain configuration It may be that a part of the element overlaps with a part of another component.

  In describing the destination guidance method of the present embodiment, a plurality of steps may be described in order, but the order of description does not necessarily limit the order in which the steps are executed. For this reason, when the method according to the present embodiment is performed, the order of the plurality of steps can be changed within a range that does not hinder the contents.

  Furthermore, the plurality of steps of the destination guidance method according to the present embodiment are not limited to being executed at different timings. For this reason, another step may occur during execution of a certain step, or a part or all of the execution timing of a certain step and the execution timing of another step may overlap.

  Next, the overall operation for determining the movement route of portable information communication system 500 according to the present embodiment will be described.

  FIG. 6 is a sequence diagram showing an overall operation for determining a movement route of portable information communication system 500. In the sequence diagram of the mobile information communication system 500 shown in FIG. 6, first, the mobile phone 100 starts communication connection with the mobile phone network 300, so that connection processing is performed (step S01).

  When the connection is established by the connection process with the mobile phone 100, the mobile phone network 300 starts communication connection with the location information server 200. When the mobile phone network 300 performs a connection process with the location information server 200, the location information server 200 is connected to the mobile phone network 300 (step S03).

  The user uses the key input unit 107 (FIG. 4) provided in the mobile phone 100 to input a departure place and a destination (step S05). Thereby, the input of the departure point information and the destination information of the user having the mobile phone 100 is accepted.

  The cellular phone 100 transmits the departure point and the destination from the terminal information transmission unit 170 (FIG. 2) to the location information server 200 via the cellular phone network 300 (step S07). At this time, the mobile phone 100 also transmits a terminal ID (identification) for identifying the mobile phone 100. When the location information server 200 receives the departure point and the destination from the mobile phone 100, the location information server 200 extracts (creates) a plurality of route candidates (movement routes) from the received departure point and destination (step S09). That is, the travel route creation unit 220 (FIG. 3) creates route candidates based on the received departure place information and destination information.

  The location information server 200 returns the extracted plurality of route candidates to the mobile phone 100 identified by the terminal ID via the location information server 200 (step S11).

  For example, FIG. 7 shows two types of routes created by the travel route creation unit 220. In FIG. 7, the departure point is A station and the destination is B city hall. And it shows that there are two route candidates (that is, a movement route) of the route R1 and the route R2 before going from the A station to the B city hall.

  The mobile phone 100 receives a plurality of route candidates from the location information server 200 via the mobile phone network 300, and selects a desired route (movement route) from the received plurality of route candidates (step S13). The mobile phone 100 transmits the selected route to the location information server 200 via the mobile phone network 300 (step S15).

  For example, as illustrated in FIG. 8, when the user selects the route R <b> 1, the mobile phone 100 transmits the selected route R <b> 1 to the location information server 200.

  When the location information server 200 obtains a route from the mobile phone 100 via the mobile phone network 300, the movement route creation unit 220 calculates and generates location information (route information) constituting the selected route (step S17). ). The location information server 200 transmits the location information of the selected route to the mobile phone 100 via the mobile phone network 300 (step S19).

  For example, as shown in FIG. 9, in the route R1 from the A station to the B city hall, position information (P1, P2,... PN) along the route R1 is transmitted to the mobile phone 100. In FIG. 9, the position information is illustrated by the position information of 11 locations P1 to P11 as an example, but the number of position information is not limited. The position information is specifically latitude and longitude information indicated by latitude and longitude.

  When the mobile phone 100 receives a plurality of pieces of position information indicating the selected route (sometimes referred to as route position information), the mobile phone 100 stores the starting point, the destination, and the route position information in the RAM 103 (FIG. 4). (Step S21). Thus, the mobile phone 100 can acquire the position information that forms the route R1 from the A station to the B city hall.

  Then, the mobile phone 100 performs a disconnection process for disconnecting the communication connection with the mobile phone network 300 in order to disconnect the communication connection with the location information server 200 (step S23). The mobile phone network 300 performs a disconnection process for disconnecting the communication connection with the location information server 200 in order to disconnect the communication connection between the mobile phone 100 and the location information server 200 (step S25).

  As described above, the user selects (determines) the route from station A to B city hall, and stores location information (for example, continuous location information) corresponding to the route in RAM 103 of mobile phone 100. be able to.

  Next, an example of the operation of the mobile phone 100 when the user carries the mobile phone 100 in which a plurality of pieces of position information are stored and moves from the A station to the B city hall will be described with reference to FIG.

  In this embodiment, the CPU 101 (FIG. 4) reads the destination guidance program for guiding the user from the departure place to the destination from the ROM 102 (FIG. 4), and executes the destination guidance program in the RAM 103 (FIG. 4). This is called guidance mode.

  FIG. 10 is a flowchart showing the operation of the mobile phone 100 when moving from the A station to the B city hall. The user operates the key input unit 107 of the mobile phone 100 to activate a guidance mode for guiding the route from the station A to the city hall B, and sets the guidance mode to be effective (step S51).

  When the guidance mode is activated, the cellular phone 100 activates the position information positioning unit 106 (step S53). The position information positioning unit 106 measures the current position of the mobile phone 100 (step S55). As the user moves from the A station to the B city hall, the position information positioning unit 106 measures the current position at a predetermined time interval (for example, 30 seconds).

  That is, the position information positioning unit 106 measures the current position of the mobile phone 100 at a predetermined time interval, and acquires the current position information of the current position.

  Then, on the way from the A station to the B city hall, the movement path determination unit 150 determines the position information stored in the RAM 103 and the current position measured by the position information positioning unit 106 (step S57).

  That is, the movement route determination unit 150 determines whether or not the divergence distance between the current position information measured in step S55 and the route information generated by the process of creating the movement route is equal to or greater than the first threshold value.

  In the present embodiment, the movement route determination unit 150 calculates a divergence distance between position information indicating a plurality of points discretely arranged as route information and current position information acquired by the current position positioning unit 140, respectively. . That is, the movement route determination unit 150 determines whether or not all the deviation distances between the acquired current position information and the position information indicating a plurality of discretely arranged points are equal to or greater than the first threshold value, The first notification output can be performed when all the deviation distances are equal to or greater than the first threshold.

  For example, it is assumed that the current position of the mobile phone 100 is an arbitrary point X. Then, the distance between the point X of the mobile phone 100 and the route information (see FIG. 9) is calculated as a deviation distance. That is, the divergence distance between the point X of the mobile phone 100 and each point of the route information P1, P2,... PN (see FIG. 9) is calculated. Then, the movement route determination unit 150 determines whether or not the divergence distance between the point X of the mobile phone 100 and the route information (P1 to PN) is equal to or greater than a first threshold (for example, 100 m).

  When the current position measured in step S55 is included in the position information stored in the RAM 103 (Yes in step S59), it is determined that the user is on the route from the station A to the city hall B, and the process proceeds to step S61. move on. That is, the deviation distance between the current position measured in step S55 and the generated route information is determined to be less than the first threshold, and the user is along the selected route, so the process proceeds to step S61.

  Note that “included in the above-described position information” includes being less than the first threshold.

  On the other hand, when the current position measured in step S55 is not included in the position information stored in the RAM 103 (No in step S59), it is determined that the user is not on the route from the station A to the city hall B. . That is, it is determined that the divergence distance between the current position measured in step S55 and the generated route information is greater than or equal to the first threshold value, indicating that the user is not along the selected route.

  For this reason, when it determines with it being more than a 1st threshold value by step S59, the alerting | reporting part 160 performs the auditory or tactile 1st alert | report output. Thereby, the mobile phone 100 notifies that it is off the movement route (step S63). Therefore, the user can recognize that he / she has deviated from the route by the notification unit 160, and can return to the original correct route. Then, the process returns to step S55.

  In step S61, when the current position of the mobile phone 100 has reached the destination (Yes in step S61), the position information positioning unit 106 is stopped (step S65). The alerting | reporting part 160 performs the 2nd alerting | reporting output which shows that the user reached | attained the destination, notifies a user (step S67), and complete | finishes.

  On the other hand, in step S61, when the current position of the mobile phone 100 has not reached the destination (No in step S61), the process returns to step S55, and the current position of the mobile phone 100 is continuously measured at a predetermined time interval. To do.

  As described above, according to the present embodiment, the mobile phone 100 can guide the user from the departure place to the destination based on the position information constituting the route (movement route) selected by the user. When the current position information indicating the user's current position deviates from the route, the user can be notified that the user has deviated from the route. Therefore, the user makes a mistake in the route without checking the display unit of the mobile phone 100. You can notice that.

  According to the present embodiment, mobile phone 100 can reliably guide the user to the destination along the selected movement route only by the user selecting the movement route.

  As mentioned above, although embodiment of this invention was described with reference to drawings, these are illustrations of this embodiment and various structures other than the above are also employable.

  For example, in the present embodiment, the movement route determination unit 150 calculates the divergence distance based on the current position information acquired by the current position positioning unit 140 and the position information acquired by the route information acquisition unit 120, It is determined whether the deviation distance is equal to or greater than a first threshold value.

  However, the present embodiment is not limited to this. For example, the movement route determination unit 150 generates a virtual route by connecting adjacent route information (see FIG. 9) with a virtual line, and the current position information acquired by the current position positioning unit 140 is perpendicular to the virtual route. The direction distance may be calculated as the deviation distance and determined.

  Thereby, the movement route determination unit 150 can perform the determination based on the first threshold value by calculating the vertical distance between the latitude and longitude information displayed by the current position information and the virtual route.

  Note that the route information is preferably position information sampled at intervals of a distance shorter than twice the first threshold value. Therefore, the first threshold value may be set to a value less than ½ of the sampled interval of the route information.

  Further, the route information may be displayed in the form of vectors and scalars that are linearly displayed, instead of coordinate information displayed as points. In this case, for example, a component with respect to the traveling direction of the movement path is displayed using a vector, and a component with respect to the movement amount is displayed using a scalar. By using a vector and a scalar, a movement vector along the traveling direction can be generated from the current position measured at a predetermined time interval and the position information measured immediately before the current position. Further, by setting the scalar amount in the direction opposite to the generated movement vector, it is possible to determine the divergence distance from the route information created as the movement route.

  That is, the mobile phone 100 can generate a route vector of the moving route based on the route information acquired by the route information acquisition unit 120. On the other hand, a movement vector can be generated by continuously positioning the current position at a predetermined time interval in the current position positioning unit 140. Therefore, the movement route determination unit 150 determines the divergence distance by comparing the movement vector generated from the current position and the route vector formed based on the route information acquired by the route information acquisition unit 120. Can do.

  As described above, by using the vector and the scalar, the movement route determination unit 150 can analytically solve the route information by detecting the direction between the movement vector and the route vector and converting the shift. In this case, the threshold value can also be determined using image processing.

  Furthermore, the movement route determination unit 150 intersects the route information acquired by the route information acquisition unit 120 with the first threshold distance based on the current position information acquired from the current position measurement unit 140. Depending on whether or not, the threshold value may be determined.
