  A plurality of health degrees calculated in advance are stored in areas 380 to 384, respectively. Each health level is associated with each health information. Therefore, each health level is also associated with each route.

  Furthermore, the plurality of environmental change influences calculated in advance are stored in areas 390 to 394, respectively. Here, the environmental change influence degree refers to the degree of influence that the environmental change in a specific route has on the body. For example, the atmospheric pressure will be described as an example of the environment as follows. That is, when there is a difference in atmospheric pressure between one point (point A) and another point (point B) on the route, this difference in atmospheric pressure has some effect on the body of the person existing on the route. May affect. By specifying the difference and the degree of influence in advance, for example, in the form of a map, it is possible to search the degree of influence of the physical condition due to the difference in environment in a specific route.

Here, the degree of influence includes the degree of influence of the environment on the body (hereinafter referred to as environmental influence degree) and the degree of influence of the environment on the body (hereinafter referred to as environmental change influence degree). The environment includes atmospheric pressure and temperature. The environmental influence degree and the environmental change influence degree regarding the atmospheric pressure are explained as follows. That is, the degree of environmental impact is quantified based on a predetermined quantification standard for the degree of influence on the physical condition (blood pressure, etc.) of the user when the user exists under a specific atmospheric pressure. Is. In this case, each atmospheric pressure is associated with the degree of influence on the body under the atmospheric pressure. This association will be described later.

  Further, the environmental change influence level is obtained by quantifying the degree of the influence on the physical condition caused by the change in the atmospheric pressure per unit time according to a predetermined quantification standard. In this case, the amount of change in atmospheric pressure and the degree of influence on the body with respect to the amount of change are associated with each other. This association will be described later.

  Referring to FIG. 5, CPU 130 that realizes mobile phone 100 according to the present embodiment will be described. FIG. 5 is a block diagram showing a functional configuration of CPU 130. This configuration is realized, for example, when each program shown in FIG. 4 is executed. Instead of the mode shown in FIG. 5, the CPU 130 is realized by combining circuits for realizing each process, or by a reconfigurable device called a so-called FPGA (Field Programmable Gate Array). You may make it implement | achieve the function similar to a function as hardware.

  As shown in FIG. 5, the CPU 130 includes an input / output unit 510, a communication control unit 520, a guidance route candidate search unit 530, a health level search unit 540, an environment data acquisition unit 550, and an influence level search unit 560. And a guidance route determination unit 570 and a display control unit 580.

  The input / output unit 510 inputs and outputs data between the outside and the inside of the CPU 130. The communication control unit 520 causes the external network connection unit 114 to execute communication processing. The communication process includes, for example, a process for accessing the server 200 to acquire position information, a process for transmitting or receiving an e-mail, and a process for making and receiving calls.

  The guide route candidate search unit 530 obtains the location information based on the signal received by the GPS antenna 102 and the data input through the GPS signal receiving unit 104 and the purpose input through the input unit 116. Based on the data representing the ground and the data read by the storage unit 150 or the external recording medium reading device 170, the candidate of the route to the destination of the user of the mobile phone 100 and the movement available on the route Search for means. The moving means includes walking, trains, airplanes and the like. A plurality of routes may be searched as long as the route to be searched is a route according to a predetermined search criterion.

  The health level search unit 540 searches the health level of the user of the mobile phone 100 based on data input via the input unit 116 or data stored in the recording medium 172. The environment data acquisition unit 550 acquires environment information (for example, temperature, pressure, altitude) on the searched route candidate by communication processing via the external network connection unit 114.

  The influence degree search unit 560 uses the environment data acquired by the environment data acquisition unit 550 and the moving means searched by the guide route candidate search unit 530 for each route searched by the guide route candidate search unit 530. For each, the degree of influence of the environment in the route or the change in the environment on the user's body (that is, the degree of influence on the environment and the degree of influence on the environment change) is searched.

  These degrees of influence are searched as follows, for example. First, a plurality of influence levels are prepared in advance as table information, for example. Each of the routes is quantified according to a standard created in advance for quantification based on the moving speed, altitude, atmospheric pressure, and the like of the user. Based on the quantified result, the corresponding degree of influence is specified from the above table. The influence degree search is not limited to the above-described mode.

  In addition, instead of searching for a specific environmental impact level or an environmental change impact level from the environmental impact level and environmental change impact level prepared in advance as a table, the environmental impact level and the environmental change impact level are calculated. Also good. For example, by using a function calculated in advance, the environmental impact level and the environmental change impact level can be calculated. In this case, information representing temperature, atmospheric pressure, and other environments is used as an input variable. A function for deriving the environmental influence degree or the environmental change influence degree based on these input variables can be described as a linear sum of the input variables, for example. In this case, since the dimensions of the input variables are different, a coefficient for making each variable dimensionless may be used for each variable. In this way, the amount of use of the data area in the storage unit 150 can be suppressed, rather than the degree of influence being created in advance as a table and stored in the storage unit 150. In addition, since the method of deriving the environmental impact or environmental change impact can be changed by replacing the function, the environmental impact or environmental change impact is calculated regardless of the value of the input variable. can do.

  The guidance route determination unit 570 determines a route to the destination based on the health level searched by the health level search unit 540 and the environmental change influence level searched by the influence level search unit 560. This determination is performed, for example, by searching for a route that is smaller than the searched health level and has the smallest environmental change influence, or by searching for a route that requires the minimum time from the current location to the destination. It is.

  The display control unit 580 executes processing for realizing image display on the display unit 140. The display control unit 580 displays an image on the display unit 140 based on the data stored in the RAM 160.

Therefore, the mobile phone 100 can execute processing for searching for a route, health level, environmental change influence level, and the like corresponding to health information input from the outside. The procedure of this process will be described later.

  Next, referring to FIG. 10, storage unit 150 includes tables 1000, 1002, 1004, 1006, and 1008 as information created in advance. Each information is created based on medical information, for example. Alternatively, the information in the tables 1006 and 1008 is created based on a so-called dive table that is generally used in scuba diving.

  These data may be stored in the storage unit 150 by the mobile phone 100 or may be stored in the database 240 of the server 200 described above. When these data exist outside the mobile phone 100, the user of the mobile phone 100 from the device (for example, the server 200) that provides these data before performing the function of guiding the route. By acquiring in advance, the mobile phone 100 can realize a function of deriving a route. The health level is created according to a predetermined quantification standard based on this data.

  Next, with reference to FIG. 11, storage unit 150 further includes a table 910 to a table 960. These tables are sequentially created according to the use of the mobile phone 100. For example, when there are a plurality of users as users of the mobile phone 100, each user creates his own data and saves it in the storage unit 150, thereby creating a table corresponding to each user.

  For example, the information on the atmospheric pressure for the first user is stored in the table 910 as the health level. Information on the atmospheric pressure for the second user is stored in the table 920. Information on atmospheric pressure for the third user is stored in the table 930.

  For example, in the table 910, the degree of influence of the atmospheric pressure on the user's physical condition is stored. Here, “0:30” indicates that the elapsed time from the start of route selection is 30 minutes. In this case, the degree of influence on cerebrovascular disease and heart disease is “0”. Further, the degree of influence on diabetes is “2.0”. The residual nitrogen concentration is “8.3”. Therefore, the first user is not affected by the cerebrovascular disease and the heart disease in the route in which the atmospheric pressure changes. In this case, since the first user does not have a cerebrovascular disease or heart disease, the air pressure will not affect the route selection.

  On the other hand, with respect to diabetes and residual nitrogen concentration, the first user is affected by the atmospheric pressure. Therefore, if the first user suffers from diabetes, or if the residual nitrogen concentration has changed compared to normal after a specific action, it is preferable to consider the air pressure when selecting the route Will occur.

  Similarly, data representing the degree of influence by the temperature on the first user as another health degree is stored in the table 940. Data representing the degree of influence by the temperature on the second user is stored in the table 950. Data representing the degree of influence by the temperature on the third user is stored in the table 960.

  In this way, for example, even when traveling with a plurality of people, the mobile phone 100 can guide a route that takes into consideration the health condition or physical condition of all the accompanying persons.

  In addition, by storing data representing the influence of the environment for each individual as a table in advance, the mobile phone 100 can retrieve the degree of influence on the user in a specific environment.

  With reference to FIG. 12, the data structure of mobile phone 100 will be further described. FIG. 12 is a diagram illustrating an aspect of storage of data representing the degree of environmental influence (environmental influence degree) and the degree of environmental change influence (environmental change influence degree) in storage unit 150.

  The storage unit 150 includes a table 1010 to a table 1030. Information regarding the first route guidance candidate is stored in the table 1010. Information regarding the second route guidance candidate is stored in the table 1020. Information regarding the third route guidance candidate is stored in the table 1030.

  For example, in the table 1010, the first route guidance candidate includes a car, an airplane, and a walk for connecting as a moving means. The elapsed time divided in advance and the moving means to be used are associated with each other. Further, for each elapsed time, the atmospheric pressure, the degree of change in atmospheric pressure, the temperature, and the degree of change in temperature are associated with each other.

  Similarly, the second route guidance candidate includes a car as the moving means. For each elapsed time divided in advance, the atmospheric pressure, the atmospheric pressure change degree, the air temperature, and the air temperature change degree are associated with each other. The same applies to the information on the third route guidance candidate in the table 1030.

  The data prepared in advance is stored in a table format, and the table is referred to according to the process, and the process for obtaining the data can be easily understood by those skilled in the art. Do not repeat.

  With reference to FIG. 13, the data structure of mobile phone 100 will be further described. FIG. 13 is a diagram illustrating an aspect of storing route information in storage unit 150. This route information is generated when the user of the mobile phone 100 inputs the current position and the target position via the input unit 116.

  The storage unit 150 includes areas 1110 to 1150. Data representing the guide route candidate is stored in area 1110. Data for specifying the position is stored in area 1120. Data representing the altitude of the position is stored in area 1130. Data representing the atmospheric pressure at that position is stored in area 1140. Data representing the temperature at that position is stored in area 1150. The data stored in areas 1110 to 1150 are associated with each other. For example, at the position “001” of the first route, the altitude is 100.0 m, the atmospheric pressure is 1013.0 hPa, and the air temperature is 20.0 degrees.

  When a plurality of routes are searched, each route is displayed on the display unit 140 based on the structure shown in FIG. The display mode on the display unit 140 will be described later.

  Next, a control structure of the mobile phone 100 will be described with reference to FIG. FIG. 14 is a flowchart showing a procedure of processing executed by control unit 120 to guide a route to the destination. This process is realized by executing a program corresponding to the process after the user of the mobile phone 100 performs an operation for instructing the start of the process.

  In step S1202, control unit 120 receives an input of a destination and an input of a desired moving means via input unit 116. In step S1204, control unit 120 searches for a guide route candidate to the destination by executing a search process prepared in advance.

  In step S1210, control unit 120 determines whether or not to obtain health information from external recording medium 172. This determination is performed, for example, by determining whether or not such an instruction for acquisition has been input via the input unit 116. If control unit 120 determines to obtain health information from recording medium 172 (YES in step S1210), the process proceeds to step S1212. If not (NO in step S1210), the process proceeds to step S1214.

  In step S1212, control unit 120 drives external recording medium reading device 170 to read health information stored in recording medium 172. The control unit 120 stores the read information in a predetermined area in the storage unit 150.

  In step S1214, control unit 120 causes display unit 140 to display a “health information input guide” menu. This display is realized, for example, by writing data for displaying the menu in the area of the RAM 160. In step S1216, control unit 120 receives input of health information according to the menu via input unit 116.

  In step S1218, control unit 120 searches for the health level (FIG. 11) of the provider of the information according to the acquired health information. For example, when the user is on the way home after scuba diving, the degree of influence on the residual nitrogen concentration in the body is searched as an item to be considered when selecting the route. Since the residual nitrogen accumulated in the body is discharged out of the body with the passage of time, the degree of influence, that is, the frequency of the residual nitrogen item of the health level, decreases with the passage of time.

  In general, in the case of leisure diving, the depth of water is 30 to 40 meters. At this time, under a high pressure of about 4 to 5 atm, compressed air having a concentration about 4 to 5 times the ground is taken into the body. Nitrogen is taken up by organs in the body at a high concentration, and it is said that it takes more than 10 hours to excrete.

  Thus, for example, in the case of residual nitrogen concentration in the body, it is possible to predict the physical condition over time by obtaining current health information, and by referring to the table, the degree of physical health in time series Can be derived.

  Referring to FIG. 14 again, in step S1300, control unit 120 executes communication processing with an external network described later. When this process is executed, communication with the server 200 that provides environment data or position information is established, and information required by the mobile phone 100 is acquired.

  In step S1220, control unit 120 searches the table stored in storage unit 150 for the environmental impact level on the guidance route candidate and the environmental change impact level. For example, the environmental impact level and the environmental change impact level are specified based on atmospheric pressure or air temperature, as shown in FIG. 12, for example. The degree of environmental impact is the number of differences with respect to an environment in which humans can comfortably spend time. The degree of influence of environmental change is calculated based on the guidance route along with the environment data on each guidance route candidate, considering that the guidance route candidate derived by well-known route search has the estimated transit time on the route. This is a quantitative representation of the degree of environmental change.

  In step S1222, control unit 120 determines whether the environmental impact level and the environmental change impact level of each guidance route candidate match the health level of the user of mobile phone 100 or not. This determination is made based on, for example, whether each degree of influence (environmental influence degree, environmental change influence degree) matches the health level of the user. If these influence levels match the health level (YES in step S1222), the process proceeds to step S1230. If not (NO in step S1222), the process proceeds to step S1224.

  In step S1224, control unit 120 adds break time data prepared in advance. The process returns to step S1220.

  In step S1230, control unit 120 determines whether or not there are any guidance route candidates. If no candidate exists (YES in step S1230), the process proceeds to step S1250. If not (NO in step S1230), the process proceeds to step S1232.

  In step S1232, control unit 120 causes display unit 140 to display the guide route candidate list, the moving means, the required time, and the rest time.

  In step S 1240, control unit 120 determines whether or not a guidance route has been selected based on data input via input unit 116. If the guide route is selected (YES in step S1240), the process proceeds to step S1260. If not (NO in step S1240), the process proceeds to step S1250.

  In step S1250, control unit 120 generates display data for prompting a change in conditions for searching for a guidance route or a change in moving means. The display data includes, for example, a message that displays “Please change the route”. Control unit 120 stores the data in a predetermined area in RAM 160. As a result, the display unit 140 displays an image that prompts the user to change the guide route search condition or the moving means.

  In step S1260, control unit 120 starts a process for guiding a route. When this process is started, display unit 140 displays an image representing the selected route. This display is performed based on the data stored in the storage unit 150 and the RAM 160 as in the above-described display processes.

  With reference to FIG. 15, the control structure of mobile phone 100 will be further described. FIG. 15 is a flowchart showing a procedure of processing executed by control unit 120 for communication between mobile phone 100 and server 200. This process is realized by the control unit 120 executing a communication program when the user of the mobile phone 100 executes a predetermined connection operation, for example.

  In step S1310, control unit 120 establishes communication with the information provider, that is, server 200. In this case, the control unit 120 causes the external network connection unit 114 to transmit a signal for establishing communication. Thereafter, the control unit 120 detects that communication is established with the server 200 via the network connection unit 114.

  In step S1320, control unit 120 transmits an environment data acquisition request on the guidance route candidate. This transmission is realized by causing the control unit 120 to transmit the packet shown in FIG. 6 to the external network connection unit 114, for example.

  In step S1330, control unit 120 receives environmental data corresponding to the acquisition request from the information provider (server 200). This data includes, for example, the structure shown in FIG.

  In step S1340, control unit 120 stores the received environment data in a predetermined area in storage unit 150. This data is stored in each area as shown in FIG. 13, for example. In step S1350, control unit 120 ends communication with server 200.

  Here, with reference to FIG. 16, the path | route which the user of the mobile telephone 100 can take is demonstrated. FIG. 16 is a diagram illustrating a route that the user can take to move from the current location 1400 to the destination 1490.

  A user of the mobile phone 100 is located at the current location 1400. When the user desires to reach the destination 1490, the user inputs data representing the destination 1490 at the current location 1400 to the mobile phone 100 via the input unit 116. Here, for example, three routes can be candidates.

  That is, this candidate includes a first route 1410, a second route 1420, and a third route 1430. The first route 1410 is a route having the shortest distance to the destination 1490. The second route 1420 represents a route for reaching the destination while bypassing the slope. The 3rd path | route 1430 is a path | route for moving so that it may pass through a flat ground so that it may not pass through a slope as much as possible. When such a route exists, the user of the mobile phone 100 inputs the above-described data to the mobile phone 100 at the current location 1400, thereby selecting the optimum route according to the health state of the user. be able to.

  For example, in the case of the first route 1410, the change degree of the atmospheric pressure and the temperature during the movement (for example, the rate of change expressed as a ratio between the change amount and the movement distance) is the second route 1420 or the third route 1430. It is thought that it is larger than those values. If the degree of change does not match the degree of health of the user's body, the mobile phone 100 sets a certain rest time on the first route 1410 that is the guide route in order to reduce the degree of change. In addition, the degree of change is searched again.

  As a result, even when the degree of change in the first route 1410 that is a candidate for the guidance route searched by a well-known search method does not match the physical health level, the user considers the rest time at the time of movement. By doing so, the first route 1410 can be selected as a route that has a small influence on the body, for example, a route that falls below a predetermined level with respect to the influence.

  In addition, the user can select the second route 1420 when desiring to select a guidance route with a lower degree of change and less time loss. Furthermore, when the user's health condition is extremely bad, the user can select the third route 1430 as a guide route candidate with a very low degree of change.

  Next, with reference to FIG. 17, the data structure of the mobile phone 100 existing on the route shown in FIG. 16 will be described. FIG. 17 is a diagram illustrating one mode of storing route information in the storage unit 150 of such a mobile phone 100.

  Storage unit 150 includes regions 1510 to 1560. Data for identifying the route is stored in area 1510. Data representing positions specified at predetermined intervals in each route is stored in area 1520. Data representing the altitude of each position is stored in area 1530. Data representing the atmospheric pressure at each position is stored in area 1540. Data representing the temperature at each position is stored in area 1550. Data representing the time at which the data in the areas 1530 to 1550 is acquired is stored in the area 1560. The data stored in areas 1510 to 1560 are associated with each other. The data shown in FIG. 17 is stored in the storage unit 150 when the user of the mobile phone 100 executes data acquisition processing at the current location 1400.

  Next, with reference to FIG. 18 and FIG. 19, the display mode of the mobile phone 100 according to the present embodiment will be described. FIG. 18 is a diagram illustrating a list of guide route candidates displayed on display unit 140.

  When the mobile phone 100 executes the guidance route search process via the input unit 116, the mobile phone 100 displays the execution result on the display unit 140. This display is realized by writing data representing the search result in the area of the RAM 160. When such data is written, the display unit 140 displays a list as shown in FIG. For example, the list displays “Route 1” to “Route 3” as routes. In “Route 1”, the first moving means is “AAAA”. The time required is 0 hour 30 minutes. The break time is 10 minutes. Further, the route represented as “Route 2” is “BBBB” as the moving means. The time required for the route is 1 hour 00 minutes. The break time is 20 minutes. Information about “Route 3” is also displayed in the same manner. The display unit 140 further displays a check box for selecting any one of the routes displayed as a list.

  In the example shown in FIG. 18, for example, the check box 1610 is selected. In such a state, when the user of the mobile phone 100 presses a determination button (not shown) as the input unit 116, the selection of the route 2 is confirmed. When “Route 2” is selected, detailed information about the route is displayed.

  That is, referring to FIG. 19, display unit 140 displays a screen representing detailed information about “Route 2”. This screen includes, for example, a title shown as route guidance mode. In this case, the guidance route is “Route 2”.

  The display unit 140 further displays the current position, the moving speed, the current time, and the estimated arrival time. The current location is displayed based on position information acquired by the GPS signal receiving unit 104, for example. The moving speed is a speed calculated based on the acceleration detected by the acceleration sensor 106. The current time is the current time specified based on the time information by the clock 118 or the GPS signal received via the GPS signal receiving unit 104. The estimated arrival time is calculated by the CPU 130 by a predetermined calculation formula based on the current time, the moving speed, and the required time according to the moving means.

  The display unit 140 further displays an icon “map display” that receives an input of an instruction for displaying a map near the route. When the user presses this icon, a map including the current position is displayed. The map information displayed at this time is map information stored in advance in the storage unit 150, for example.

  As described above, the mobile phone 100 according to the first embodiment of the present invention uses the route according to the search criteria determined in advance according to the current position, the destination, and the health state of the user of the mobile phone 100. Search for. In this case, a route that takes into account the user's health condition, physical condition, etc. is searched. Therefore, compared to using only the time, cost, number of transfers, and other criteria that do not depend on the user for each route, the user selects a route that is more appropriate, for example, less affected by the user's disease. can do.

  In addition, according to the mobile phone 100 according to the present embodiment, since it is possible to receive a plurality of health status inputs, the mobile phone 100 functions as a route guidance device capable of guiding a path that takes into account the health status and physical condition of a plurality of accompanying persons. can do.

<Second Embodiment>
Hereinafter, a second embodiment of the present invention will be described. The route guidance device according to the present embodiment calculates the degree of change in the environment while guiding the route to the destination, and based on the result, determines the degree of influence on the user of the device. It differs from the above-described embodiment in that it has a notification function. Note that the guidance route device according to the present embodiment has the same hardware configuration as that of the first embodiment. Their functions are the same. Therefore, description thereof will not be repeated here.

  Referring to FIG. 20, CPU 130 that realizes the route guidance device according to the present embodiment will be described. FIG. 20 is a block diagram showing a functional configuration of CPU 130.

  CPU 130 further includes a degree-of-change calculator 1810 in addition to the configuration shown in FIG. The degree-of-change calculation unit 1810 acquires environmental data to the destination regularly or irregularly while the mobile phone 100 that is one mode of the route guidance device is moving. When the degree-of-change calculating unit 1810 periodically acquires environmental data, for example, communication processing is started and processing for receiving environmental data is executed at each preset update timing.

  On the other hand, when the degree-of-change calculating unit 1810 acquires environmental data irregularly, a process for the acquisition is executed according to, for example, a predetermined random variable. Or switching of a moving means may be detected and environmental data may be acquired according to the detection. Furthermore, the environmental data may be acquired by a user performing a button operation for executing data update.

  Based on the environmental data acquired in this way, the change degree calculation unit 1810 searches again for the environmental change influence degree and the environmental influence degree for the moving user. The degree of change calculation unit 1810 generates data for causing the display unit 140 to display an image based on the calculation result. This data is for notifying the user of the degree of influence on the body due to environmental changes.

  With reference to FIG. 21, the control structure of the route guidance device according to the present embodiment will be described. FIG. 21 is a flowchart showing a procedure of processing executed by CPU 130.

  In step S 1910, CPU 130 receives input of time information from clock 118. In step S1920, CPU 130 determines whether or not the time specified based on the time information is the timing for acquiring environmental data. If the time is the timing for acquiring environmental data (YES in step S1920), the process proceeds to step S1930. If not (NO in step S1920), the process ends.

  In step S1930, CPU 130 executes a process for acquiring environment data. That is, the CPU 130 starts communication processing with the server 200 via the external network connection unit 114. When this process is executed, the current environment data is input to the mobile phone 100 and stored in the storage unit 150.

  In step S1940, CPU 130 calculates the degree of environmental change based on the acquired data. The degree of change is, for example, a change in atmospheric pressure or temperature per unit moving distance.

  In step S1950, CPU 130 searches for the environmental change influence level again based on the result of calculation in step S1940. This search is performed by referring to data stored in storage unit 150, for example, data shown in FIGS.

  In step S1960, CPU 130 generates display data for displaying the retrieved environmental change influence degree as an image. In step S1970, CPU 130 causes display unit 140 to output the display data. As a result, the display unit 140 displays the degree of influence of the environment change retrieved again based on the updated environment data, for example, by icon, color display, or the like.

  As described above, according to the route guidance device according to the second embodiment of the present invention, the environmental data is acquired regularly or irregularly. The route guidance device displays the influence due to the environmental change based on the environmental change influence degree newly searched using the acquired environmental data. In this way, the user can recognize the influence due to the change in the environment, and thus can take measures such as changing the moving means and changing the route.

  In a certain aspect, when the route guidance device is realized by a mobile phone, the user receives a more effective route guidance by using an additional service of the mobile phone during route guidance of the guidance route. be able to.

  That is, as an additional service of a mobile phone, there is a service in which environmental information such as weather and temperature in a region desired by the user is periodically updated without requiring a sequential operation by the user. By applying such an update function to the route guidance device according to the present invention, the device periodically acquires environmental data on the guidance route, and sequentially updates the environmental impact level or the environmental change impact level. Can do. As a result, the user can select a route that matches the actual situation.

  Further, the route guidance device determines whether or not guidance that does not impair the health of the user is performed as scheduled on the initially set guidance route. Based on the result of the determination, the route guidance device notifies the user that if necessary, it is necessary to add rest time and to review other calculation conditions. Since the route can be searched again according to this notification, the route according to the physical condition of the user is searched and presented.

<Third Embodiment>
Hereinafter, a third embodiment of the present invention will be described. The route guidance device according to the present embodiment is different from the above-described embodiments in that it has a function of changing user health information. The hardware configuration of the route guidance device according to the present embodiment is the same as the hardware configuration in each of the embodiments described above. Their functions are the same. Therefore, description thereof will not be repeated here.

  With reference to FIG. 22, CPU 130 according to the present embodiment will be described. FIG. 22 is a block diagram showing a functional configuration of CPU 130.

  The CPU 130 includes a health level changing unit 2010 in addition to the configuration shown in FIG. The health level changing unit 2010 is realized by executing a program for changing the health level. When hardware that executes circuit elements or other specific processing is used instead of the CPU 130, the function according to the present embodiment performs a process of acquiring the health level and updating it based on the acquired data. You may implement | achieve by the element to perform.

  The health level changing unit 2010 overwrites and updates the health level stored in the storage unit 150 based on the health level information input via the input / output unit 510. The health level change unit 2010 executes the process in response to an input of an instruction for change via the input unit 116, for example.

  With reference to FIG. 23, the control structure of the route guidance device according to the present embodiment will be described. FIG. 23 is a flowchart showing a procedure of processing executed by CPU 130 to change the health level.

  In step S2110, CPU 130 detects an input of an instruction from outside via input unit 116. In step S2120, CPU 130 determines whether or not the instruction is an instruction for changing the health level. If the instruction is an instruction for changing the health level (YES in step S2120), the process proceeds to step S2130. If not (NO in step S2120), the process ends.

  In step S <b> 2130, CPU 130 reads health degree data already stored from a predetermined area in storage unit 150. CPU 130 stores the read data in the display area of RAM 160. The display unit 140 displays the currently stored health level. Thereby, the user of the mobile phone 100 can recognize the health level currently stored.

  In step S2140, CPU 130 receives the input of health data via input unit 116. For example, when the input unit 116 is realized by a numeric button, the CPU 130 receives input of health degree data in response to pressing of the numeric button. The input data is stored in a storage area temporarily secured in the RAM 160.

  In step S2150, CPU 130 determines whether or not an instruction for determining health degree data has been input. If the instruction has been input (YES in step S2150), the process proceeds to step S2160. If not (NO in step S2150), the process returns to step S2140.

  In step S2160, CPU 130 stores the input health level in a predetermined region in storage unit 150.

  As described above, the route guidance device according to the third exemplary embodiment of the present invention receives the input of a new health level instead of the health level already held, so that the data structure in the storage unit 150 is changed. Can be changed. When the instruction for searching for the health level is output by the CPU 130, the route guidance device searches again for the changed health level. The route guidance device searches for a route based on the health level after the search.

  If it does in this way, the user of the said apparatus can search the path | route according to the change, when the health condition changes in reality. In addition, regardless of the actual health state, the route guidance device searches for the health level based on the input information. Therefore, for example, since the user can select a route for increasing the load on the body, it can be used for purposes such as physical training.

  Specifically, when the route guidance device searches for the physical health level, the user can arbitrarily set the physical health level. The route guidance device provides a route that can enhance the physical strength of the user's body based on the health level after setting. The user switches the operation mode of the route guidance device to the physical training mode by operating the input unit 116 after the physical health level is searched. The user increases the level of physical health according to the user's judgment while referring to the retrieved health level. The user inputs data by operating the input unit 116. In this way, the user can select an environment guidance route that is more severe than the current health condition. Thereby, the path | route guidance apparatus which can strengthen a physical strength by increasing the environmental load to a user's body is provided.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

It is a block diagram showing the hardware constitutions of the mobile telephone 100 which is an aspect of the route guidance apparatus which concerns on the 1st Embodiment of this invention.
