Description

  The present invention relates to a portable terminal, a reference route management program, and a reference route management method, and more particularly to a portable terminal, a reference route management program, and a reference route management method that can indicate a current position.

  An example of background art is disclosed in Patent Document 1. The portable terminal disclosed in Patent Document 1 measures the current position using a positioning function, and detects a user's operation using a body motion sensor. The detected motion is output as motion data and used to determine whether the motion is moving along the normal movement pattern. For example, when the degree of coincidence between the operation pattern and the normal movement pattern is high, the positioning time interval for positioning the current position is lengthened. On the other hand, when the degree of matching between the motion pattern and the normal movement pattern is low, the positioning time interval for positioning the current position is shortened.

  Referring to FIG. 1, a mobile phone 10 according to an embodiment of the present invention is a smartphone as an example, and includes a vertically long flat rectangular housing 12. However, it should be pointed out in advance that the present invention can be applied to any portable terminal such as a tablet terminal, a tablet PC, and a PDA.

  A main surface (front surface) of the housing 12 is provided with a display 14 made of, for example, liquid crystal or organic EL and functioning as a display unit. A touch panel 16 is provided on the display 14.

  A speaker 18 is built in the main surface of one end of the housing 12 in the vertical direction, and a microphone 20 is built in the main surface of the other end in the vertical direction.

  The main surface of the housing 12 is provided with a call key 22a, an end key 22b, and a menu key 22c as hard keys 22 constituting input operation means together with the touch panel 16 in this embodiment.

  For example, the user inputs a telephone number by performing a touch operation on the dial pad displayed on the display 14, and a voice call is started when the call key 22a is operated. When the end key 22b is operated, the voice call is ended. Further, the power supply of the mobile phone 10 can be turned on / off by long-pressing the end call key 22b. Further, when the call end key 22b is pressed for a short time while the screen is displayed on the display 14, the power of the display 14 and the touch panel 16 is turned off.

  When the menu key 22c is operated, the home screen is displayed on the display 14. The user can select an object by touching the GUI displayed on the display 14 in that state with the touch panel 16 and confirm the selection.

  In the following description, GUIs such as icons and soft keys displayed on the display 14 may be collectively referred to as objects.

  Referring to FIG. 2, the mobile phone 10 of the embodiment shown in FIG. 1 includes a processor 30 or the like also referred to as a computer or a CPU. The processor 30 includes a wireless communication circuit 32, an A / D converter 36, a D / A converter 38, an input device 40, a display driver 42, a flash memory 44, a RAM 46, a touch panel control circuit 48, a GPS circuit 50, and an attitude sensor 54. The direction sensor 56 and the power supply circuit 58 are connected. An antenna 34 is connected to the wireless communication circuit 32, the display 14 is connected to the display driver 42, the touch panel 16 is connected to the touch panel control circuit 48, a GPS antenna 52 is connected to the GPS circuit 50, and a power source is connected. A secondary battery 60 is connected to the circuit 58.

  The processor 30 controls the entire mobile phone 10. In the RAM 46 functioning as a storage unit, all or a part of a program preset in the flash memory 44 is expanded when used, and the processor 30 operates according to the program on the RAM 46. The RAM 46 is further used as a working area or a buffer area of the processor 30.

  The input device 40 includes the three hard keys 22 shown in FIG. Therefore, a key operation on the hard key 22 is accepted. Information (key data) of the hard key 22 that has accepted the input operation is input to the processor 30 by the input device 40.

  The wireless communication circuit 32 is a circuit for transmitting and receiving radio waves for voice calls and mails through the antenna 34. In the embodiment, the wireless communication circuit 32 is a circuit for performing wireless communication by the CDMA method. For example, based on a call (voice transmission) operation accepted by the touch panel 16, the wireless communication circuit 32 executes a voice transmission process under the instruction of the processor 30 and outputs a voice transmission signal via the antenna 34. The voice transmission signal is transmitted to the other party's telephone through the base station and the communication network. When a voice incoming call process is performed at the other party's telephone, a communicable state is established and the processor 30 executes a call process.

  The microphone 20 shown in FIG. 1 is connected to the A / D converter 36, and the analog audio signal obtained from the microphone 20 as described above is converted into digital audio data by the A / D converter 36, and the processor 30. On the other hand, the speaker 18 shown in FIG. 1 is connected to the D / A converter 38. The D / A converter 38 converts digital audio data into an analog audio signal and supplies the analog audio signal to the speaker 18 via an amplifier. Therefore, sound based on the sound data is output from the speaker 18. In a state where the call process is being executed, the sound collected by the microphone 20 is transmitted to the other party's telephone, and the sound collected by the other party's telephone is output from the speaker 18.

  The display driver 42 is connected to the display 14 shown in FIG. 1. Therefore, the display 14 displays a video or an image according to video data or image data output from the processor 30. The display driver 42 includes a video memory that temporarily stores data for display, and the data output from the processor 30 is stored in the video memory. The display driver 42 displays an image on the display 14 according to the contents of the video memory. That is, the display driver 42 controls display on the display 14 connected to the display driver 42 under the instruction of the processor 30. The display 14 is provided with a backlight, and the display driver 42 controls the brightness of the backlight and lighting / extinguishing in accordance with instructions from the processor 30.

  The touch panel 16 shown in FIG. 1 is connected to the touch panel control circuit 48. The touch panel control circuit 48 applies necessary voltage and the like to the touch panel 16, and also processes a touch start signal indicating the start of touch on the touch panel 16, an end signal indicating the end of touch, and coordinate data indicating the touched touch position. Enter 30. Therefore, the processor 30 determines the touched object based on the coordinate data and the change in the coordinate data.

  For example, when the touch panel 16 is touched, the touch area is detected by the touch panel 16. At this time, the touch panel control circuit 48 sets the center of gravity of the touch area as the touch position, and inputs the coordinates of the center of gravity to the processor 30. That is, the center of gravity of the touch area in the touch operation indicates the touch start position, end position, or current touch position. However, in another embodiment, instead of the center of gravity, a position where a finger or the like first touches the touch panel 16 may be set as the touch position.

  The touch panel 16 is a capacitive touch panel that detects a change in electrostatic capacitance that occurs between the surface of the touch panel 16 and an object such as a finger (hereinafter referred to as a finger for convenience). The touch panel 16 detects that one or more fingers touched the touch panel 16, for example. Therefore, the user inputs an operation position, an operation direction, and the like to the mobile phone 10 by performing a touch operation on the surface of the touch panel 16. For this reason, the touch panel 16 may be referred to as a pointing device.

  Here, the touch operation of the present embodiment includes a tap operation, a long tap operation, a flick operation, a swipe (slide) operation, and the like.

  The tap operation is an operation of releasing (releasing) the finger from the surface of the touch panel 16 in a short time after making the finger touch (touch) the surface of the touch panel 16. The long tap operation is an operation in which a finger is kept in contact with the surface of the touch panel 16 for a predetermined time or longer and then the finger is released from the surface of the touch panel 16. The flick operation is an operation of bringing a finger into contact with the surface of the touch panel 16 and flipping the finger in an arbitrary direction at a predetermined speed or higher. The swipe (slide) operation is an operation of moving the finger in any direction while keeping the finger in contact with the surface of the touch panel 16 and then releasing the finger from the surface of the touch panel 16.

  The above swipe operation includes a so-called drag operation in which a finger touches an object displayed on the surface of the display 14 to move the object. In addition, an operation of releasing a finger from the surface of the touch panel 16 after the drag operation is referred to as a drop operation.

  In the following description, a tap operation, a long tap operation, a flick operation, a swipe operation, a drag operation, and a drop operation may each be described with “operation” omitted. The touch operation is not limited to the user's finger, and may be performed with a stylus pen or the like.

  In this embodiment, when a predetermined time (for example, 15 seconds) elapses without operation, the display 14 and the touch panel 16 are automatically turned off.

  The GPS circuit 50 is activated when measuring the current position. When a GPS satellite signal received by the GPS antenna 52 is input, the GPS circuit 50 executes a positioning process based on the GPS signal. As a result, latitude, longitude, and altitude (altitude) are calculated as GPS information (position information).

  Further, in FIG. 1, only one GPS satellite is drawn for simplicity, but it is necessary to receive GPS signals from four or more GPS satellites in order to three-dimensionally determine the current position. However, even if GPS cannot be received from four or more GPS satellites, longitude and latitude can be calculated by two-dimensional positioning as long as GPS signals can be received from three GPS satellites.

  The GPS circuit 50 and the GPS antenna 52 collectively function as a receiving unit. When the current position is measured, in addition to the GPS signal transmitted from the GPS satellite, a signal transmitted from the base station, a signal transmitted from the access point of the wireless LAN, or the like is also used.

  The attitude sensor 54 detects the tilt and movement of the mobile phone 10. For example, the attitude sensor 54 detects a gyro sensor that detects rotation (angular velocity) of three axes (X, Y, Z) in the mobile phone 10 and an acceleration in the three axes (X, Y, Z) direction of the mobile phone 10. The acceleration sensor is integrally formed by MEMS (Micro Electro Mechanical Systems) technology. Therefore, the posture sensor 54 is sometimes called a six-axis motion sensor. Then, the processor 30 detects the inclination (angle) and movement of the mobile phone 10 based on the triaxial angular velocity and triaxial acceleration output from the attitude sensor 54.

  For example, when any screen is displayed on the display 14, the attitude at which the mobile phone 10 is held is detected using the angular velocity and acceleration, and the display direction corresponding to the detected attitude is set. In this embodiment, if the mobile phone 10 is held in the vertical orientation, the display direction is set to the vertical orientation, and if the mobile phone 10 is held in the horizontal orientation, the display direction is set to the horizontal orientation. .

  In other embodiments, an acceleration sensor and a gyro sensor may be provided in place of the attitude sensor 54.

  The direction sensor 56 is sometimes called an electronic compass, and includes three geomagnetic sensors and a control circuit. The control circuit extracts the geomagnetic data from the magnetic data detected by the three geomagnetic sensors and outputs it to the processor 30. The processor 30 calculates the azimuth angle (azimuth or direction) based on the geomagnetic data output from the control circuit, and stores it in the buffer of the RAM 46 as the direction of the mobile phone 10. Here, the azimuth angle of the present embodiment is set to 90 degrees in the east (E), 180 degrees in the south (S), and 270 degrees in the west (W), with north (N) being 0 degrees. In addition, although the Hall element is used for each location magnetic sensor, MR (Magnet-Resistive) element and MI (Magnet-Impedance) element may be used. For example, when a map function described later is executed, a map is displayed in accordance with the calculated azimuth angle.

  Note that the attitude sensor 54 and the azimuth sensor 56 may be collectively referred to as a detection unit. In another embodiment, the attitude sensor 54 and the orientation sensor 56 may be integrally formed.

  The power circuit 58 is an IC for power management, and the power circuit 58 supplies power based on the voltage of the secondary battery 60 to the entire system. Here, a state in which the power supply circuit 58 supplies power to the entire system is referred to as a power-on state. On the other hand, a state where the power supply circuit 58 is not supplying power to the entire system is referred to as a power-off state. As described above, the power supply circuit 58 is activated when the end-call key 22b is long-pressed (power-on operation) in the power-off state, and the end-call key 22b is long-pressed (power-off operation) in the power-on state. And stopped. Further, even when the power is off, the power supply circuit 58 is activated when an external power supply is connected to an external power connector (not shown) and power is supplied (charged) to the secondary battery 60, and the secondary battery 60 is fully charged. Stops when a state of charge is detected. “Charging” means that the external power supply connector is connected to the external power supply, receives power supply from the external power supply, and the secondary battery 60 stores electric energy. The power supply circuit 58 and the secondary battery 60 may be collectively referred to as a power supply unit.

  The mobile phone 10 according to the present embodiment can execute a positioning function that measures the current position using a GPS signal or the like. It is also possible to execute a map function indicating the current position on the map using this GPS function. In addition, the map function includes a route guidance function, and the user can set an arbitrary reference route each time it is used, or can register a reference route in advance.

  FIG. 3 is an illustrative view showing one example of a display in a state where the map function is executed. Referring to FIG. 3, the display range of display 14 includes a status display area 70 and a function display area 72. In the status display area 70, a pictograph indicating the radio wave reception status by the antenna 34, a pictograph indicating the remaining battery capacity of the secondary battery 60, and a time are displayed. A map is displayed in the function display area 72. In addition, since the route guidance function of the map function is executed, a position where movement starts (hereinafter referred to as start position) and a position where movement ends (hereinafter referred to as end position) are indicated on the map. A reference route connecting the start position and the end position is shown. In the route guidance function, the reference route is automatically set when the user determines the start position and the end position. Since a method for automatically setting a reference route from a start position and an end position is widely known, a detailed description thereof is omitted here.

  For example, the user can go from the start position to the end position by moving according to the reference route displayed on the map. Further, during movement, the current position (movement position) is periodically measured and it is monitored whether it is moving correctly according to the reference route. Therefore, when the user deviates from the reference route, a route for returning to the reference route is searched. In addition, the current position measured periodically, that is, the sequential movement position is recorded as a movement route. When the user reaches the end position, that is, when the movement position and the end position coincide with each other, if the recorded movement route deviates from the reference route, the movement route is registered (stored) as the reference route. In another embodiment, when the user deviates from the reference route on the way, the reference route for reaching the end position from the current position may be reset.

  Here, when the use of the route guidance function is started, the current position is measured as the movement start position. If the movement start position matches the start position of the registered reference route, the next position is estimated by detecting the operation of the mobile phone 10.

  In the present embodiment, since the movement of the mobile phone 10 can be detected by the attitude sensor 54 and the azimuth sensor 56, the next position is estimated from the angular velocity, acceleration, and azimuth obtained from the attitude sensor 54 and the azimuth sensor 56. The That is, the attitude when the mobile phone 10 moves from the triaxial angular velocity is obtained, the direction in which the mobile phone 10 moves is obtained from the azimuth angle, and the amount (distance) by which the mobile phone 10 moves from the triaxial acceleration is calculated. Desired. Then, for example, the next position with respect to the movement start position is estimated from the posture and direction when the mobile phone 10 moves and the amount of movement obtained in this way. If the estimated position is on the reference route, the next position is continuously estimated. That is, the next position is further estimated with respect to the estimated previous position.

  As described above, since the next position can be estimated without using the positioning function without performing communication such as receiving a GPS signal, the power consumed for performing communication is reduced, and the reference route is reduced. The power consumption when moving according to can be suppressed. In particular, in this embodiment, since the next position can be estimated using the attitude sensor 54 and the orientation sensor 56 that are turned on while the map function is being executed, the power consumption described above can be reduced. The suppressing effect is particularly demonstrated.

  Further, since the next position is continuously estimated when the estimated position is on the route, the power consumption is always suppressed if the user is moving according to the reference route.

  Next, when the measured movement start position does not coincide with the start position of the reference route, the next position is measured by the positioning function. For example, if the user reads out a registered reference route and starts moving, but starts moving from a position that is completely unrelated to the starting position of the reference route, the movement starting position and the starting position of the reference route are It does not match. In such a case, the next position is measured by the positioning function. That is, if the position of the user is not on the reference route and the next position cannot be estimated, the next position of the user can be measured.

  Similarly, when the estimated previous position is not on the reference route, the next position of the user can be measured. For example, even if the user deviates from the reference route while moving according to the reference route, the user's position can be measured appropriately.

  Further, when the estimation of the next position is repeated, it is conceivable that the estimation accuracy is lowered and the estimated next position is not on the reference route even if the user does not deviate from the reference route. However, in this embodiment, if the estimated position is lowered and the estimated next position is not on the reference route, the positioning function is executed and the next position can be measured. And if the next position measured is on a reference route, it will return to the state which can estimate the next position accurately.

  Furthermore, when the user reaches the end position of the reference route, if all the movement positions that make up the recorded movement route are not on the reference route, a new reference route is created based on the recorded movement route. And a new reference route is registered. For example, as shown in FIG. 4, the user may move away from the reference route shown in FIG. 3 and reach the end position after returning to the reference route on the way. In this case, in addition to the reference route shown in FIG. 3, a new reference route shown in FIG. 4 is created and registered. Thus, if the user moves a route other than the registered reference route, the movement route is registered as a new reference route. Therefore, there are more scenes where the next position can be estimated when the user moves.

  When registering a moving route as a reference route, a new reference route is created so that all moving positions are included in the registered reference route. For example, when it is determined whether the estimated previous position is on the reference route, a movement position that matches the estimated next position is searched from the reference route. If a movement position that matches the estimated next position is found, it is determined that the estimated next position is on the reference route.

  In this embodiment, when it is determined whether the movement start position matches the start position of the reference route, or when it is determined whether the next position is on the reference route, a reference position (start value) If the movement start position or the next position is within a range shorter than a predetermined distance (for example, 6 m) with respect to each movement position constituting the reference route or the reference route, it is determined that they match or are on the reference route. .

  In the embodiment, the movement start position can be appropriately measured by using a GPS signal or the like. Furthermore, if the next position can be estimated, the next position can be appropriately estimated by using the attitude sensor 54 and the direction sensor 56 that detect the movement of the mobile phone 10.

  Further, the map data in the map function may be stored in advance in the flash memory 44 of the mobile phone 10, or a necessary amount may be downloaded from the network every time it is used.

  In another embodiment, an icon indicating the current position may be displayed on the displayed map based on the next position measured or the estimated next position.

  The features of the present embodiment have been outlined above. Hereinafter, a detailed description will be given using the memory map shown in FIG. 5 and the flowchart shown in FIG.

  Referring to FIG. 5, program storage area 302 and data storage area 304 are formed in RAM 46. As described above, the program storage area 302 is an area for reading and storing (developing) part or all of the program data set in advance in the flash memory 44 (FIG. 2).

  The program storage area 302 stores a reference route management program 310 executed when moving according to the reference route. The program storage area 302 also stores a program for executing the positioning function, a program for executing the map function, and the like.

  Subsequently, in the data storage area 304 of the RAM 46, a moving position buffer 330, a reference route buffer 332, an angular velocity buffer 334, an acceleration buffer 336, an azimuth angle buffer 338, an estimated moving position buffer 340, a moving path buffer 342, and the like are provided. Reference route data 344 and the like are stored.

  The movement position buffer 330 temporarily stores the current position measured, that is, the movement start position and the movement position. The reference route buffer 332 temporarily stores the read reference route. In the angular velocity buffer 334, the three-axis angular velocities output from the attitude sensor 54 are temporarily stored. The acceleration buffer 336 temporarily stores triaxial accelerations output from the attitude sensor 54. The azimuth angle buffer 338 temporarily stores the azimuth angle calculated based on the output of the azimuth sensor 56. The estimated next position is temporarily stored in the estimated movement position buffer 340. In the movement path buffer 342, the movement start position, the measured next position, and the estimated next position are sequentially recorded as the movement position.

  The reference route data 344 includes data indicating a reference route registered in advance by a user or the like.

  The data storage area 304 temporarily stores map data to be displayed, stores address book data, and the like, and is provided with other flags and timers (counters) necessary for program execution. .

  The processor 30 controls the reference route shown in FIG. 6 under the control of other OS such as Windows (registered trademark) -based OS and Linux (registered trademark) -based OS such as Android (registered trademark) and iOS (registered trademark). Process multiple tasks in parallel, including management processing. Note that the route guidance processing when the map function is being executed is also performed in parallel with the above processing. Since the route guidance processing is already well known and is not the essential content of the present invention, illustration and description thereof are omitted.

  FIG. 6 is a flowchart of the reference route management process. For example, when the map function is executed and the route guidance function is executed, the reference route management process is started. In step S1, the processor 30 measures the movement start position. That is, the positioning function is executed and the movement start position (current position) is measured. The measured movement start position is stored in the movement position buffer 330. Subsequently, the processor 30 that executes the process of step S <b> 3 records the movement start position in the movement path buffer 342. That is, the measured movement start position is recorded in the movement path buffer 342 as the first movement position. In addition, the processor 30 which performs the process of step S1 functions as a movement start position positioning part or a positioning part.

  Subsequently, in step S5, the processor 30 determines whether or not a reference route including a start position that matches the movement start position is registered. That is, the processor 30 determines whether or not the reference route data 344 includes a reference route that includes a start position that matches the first movement position stored in the movement position buffer 330. If “NO” in the step S5, for example, if a reference route including a start position that coincides with the movement start position is not registered, the processor 30 proceeds to the process of step S17. The processor 30 that executes the process of step S5 functions as a determination unit.

  If “YES” in the step S5, for example, if a reference route including a start position that matches the movement start position is registered, the processor 30 reads the reference route in a step S7. For example, a reference route including a start position that matches the movement start position is read from the reference route data 344 and stored in the reference route buffer 332.

  Subsequently, in step S9, the processor 30 determines whether or not the processing is finished. For example, it is determined whether the user has reached the end position of the reference route and route guidance has ended. If “YES” in the step S9, for example, when the route guidance is finished, the processor 30 proceeds to a process of step S25.

  On the other hand, if “NO” in the step S9, for example, if route guidance is being performed, the processor 30 estimates the next position in a step S11. That is, the next position with respect to the previous movement position recorded in the movement path buffer 342 is stored in the angular velocity stored in the angular velocity buffer 334, the acceleration stored in the acceleration buffer 336, and the azimuth angle buffer 338. Estimated based on azimuth. Further, the estimated next position is temporarily stored in the estimated movement position buffer 340. Subsequently, in step S13, the processor 30 records the movement position in the movement path buffer 342. That is, the next position stored in the estimated movement position buffer 340 is recorded in the movement path buffer 342 as the movement position. In addition, the processor 30 which performs the process of step S11 functions as an estimation part.

  Subsequently, in step S15, the processor 30 determines whether or not the movement position is on the reference route. That is, the processor 30 determines whether there is an estimated next position stored in the estimated movement position buffer 340 on the reference route stored in the reference route buffer 332. The processor 30 that executes the process of step S15 functions as a reference route determination unit or a route determination unit.

  If “YES” in the step S15, that is, if the estimated previous position is on the reference route, the processor 30 returns to the process of the step S9. If the route guidance has not ended, the estimated previous position is on the reference route, and therefore the next position is further estimated in step S11.

  On the other hand, if “NO” in the step S15, for example, the user deviates from the reference route, and if the estimated previous position is not on the reference route, the processor 30 in the step S17 determines whether or not the end is performed as in the step S9. Determine whether. If “YES” in the step S17, for example, when the route guidance is finished, the processor 30 proceeds to a process of step S25.

  On the other hand, if “NO” in the step S17, that is, if the route guidance is continued, the processor 30 measures the next position in a step S19. For example, since the estimated previous position is not on the reference route, the positioning function is executed to determine the next position. The next position obtained by positioning is stored in the movement position buffer 330. Subsequently, in step S21, the processor 30 records the movement position in the movement path buffer 342. That is, the next position stored in the movement position buffer 330 is recorded in the movement path buffer 342. In addition, the processor 30 which performs the process of step S19 functions as a 1st positioning part or a 2nd positioning part.

  Subsequently, in step S23, the processor 30 determines whether or not the movement position is on the reference route. For example, it is determined whether the user has returned to the reference route. Specifically, the processor 30 determines whether or not the movement position stored in the movement position buffer 330 is on the reference route stored in the reference route buffer 332. If “YES” in the step S23, for example, when the user returns to the reference route, the processor 30 returns to the process of the step S9. If the route guidance is not completed, the next position is estimated in the process of step S11.

  On the other hand, if “NO” in the step S23, for example, if the user has not returned to the reference route, the processor 30 returns to the process of the step S17. If the route guidance is not completed, the next position is determined in the process of step S19. If “NO” is determined in the step 5, the reference route is not stored in the reference route buffer 332, and therefore “NO” is always determined in the process of step S 23.

  Here, when the route guidance is completed and “YES” is determined in step S9 or step S17, the processor 30 determines in step S25 whether or not the moving route is not on the reference route. That is, it is determined whether the user has moved to the end position without departing from the movement route. Specifically, it is determined whether or not each movement position stored in the movement route buffer 342 is on the reference route stored in the reference route buffer 332. If “NO” in the step S25, that is, if each movement position stored in the movement route buffer 342 is on the reference route and the user moves to the end position without departing from the reference route, the processor 30 refers to it. The route management process ends.

  If “NO” in the step S25, for example, a part of the movement position stored in the movement route buffer 342 is not on the reference route, and the user arrives at the final position after leaving the reference route on the way. In step S27, the processor 30 creates a new reference route based on the movement route. For example, a new reference route including all the movement positions stored in the movement route buffer 342 is created. Subsequently, in step S29, the processor 30 registers a new reference route. That is, the created new reference route is added (stored) as data constituting the reference route data 344. Then, when the process of step S29 ends, the processor 30 ends the reference route management process. Further, the processor 30 that executes the process of step S27 functions as a creation unit, and the processor 30 that executes the process of step S29 functions as a registration unit.

  In Step S9 or Step S17, it is determined that the route guidance is finished, and “YES” is determined even when the route guidance function is finished or other functions using the route guidance function are finished. In addition, these functions may be terminated in response to a user operation, or may be terminated in response to an event such as an incoming call.

  Also, in step S25, it may be determined whether all registered reference routes and recorded travel routes do not match. That is, it is determined whether the recorded travel route is a route that the user has never taken by the route guidance function. When it is determined by the route guidance function that the route has never been taken, steps S27 and S29 are executed, and the recorded travel route is registered as a new reference route.

  In another embodiment, the route guidance function may be executed not only by the map function but also by other functions. For example, the route guidance function may be executed by a sports assistance function for assisting sports such as running or cycling performed by the user, a mountain climbing assistance function for displaying a mountain climbing route when climbing, or the like. In the sport assistance function, the running course is registered in advance by the user as a reference route. When the user runs according to the running course (reference route), the movement position, that is, the next position is estimated as in this embodiment.

  In other embodiments, when positioning the current position, only the GPS signal may be used, or only the signal transmitted from the access point of the wireless LAN may be used. In still another embodiment, when the next moving position is estimated, a signal transmitted from the base station or a signal transmitted from the access point of the wireless LAN may be used.

  In another embodiment, the next position may be estimated after the movement start position is measured, moved a certain distance, or after a certain time has elapsed. In this case, the current position may be measured at regular intervals while moving a certain distance or while a certain time has elapsed.

  The reference route may be registered based on a movement route when the user actually moves, or a route set in advance by the user may be registered as the reference route.

  In another embodiment, when a user has moved a route that has not been registered or has not been set many times, the route may be registered as a reference route. In this case, even if the route guidance function is not executed, the route guidance function may be executed when conditions such as the time of movement, the distance moved, or the time moved are satisfied. As a result, the current position can be estimated on the route that the user often passes.

  In still other embodiments, the reference route data 344 may be stored in the flash memory 44 instead of the RAM 46.

  In another embodiment, when registering a reference route, for example, a moving position at a point where the moving direction has changed may be selected, and only the selected moving position may be included in the registered reference route. Further, when determining whether the estimated next position is on the reference route, an equation connecting each moving position is established, and it is determined whether the estimated next position satisfies the equation. If the estimated next position satisfies the equation, it is determined that the estimated next position is on the reference route.

  In other embodiments, the user may be able to register the reference route at an arbitrary position during movement. For example, in another embodiment, when the user is moving along the reference route, the reference route is automatically registered when the user stops running based on the acceleration output from the attitude sensor 54. You may make it do. Further, the reference route may be registered when the user performs a predetermined operation while moving.

  In yet another embodiment, before a registered reference route is registered, the travel route may be displayed on a map so as to confirm with the user whether there is an error in the travel route. Further, when the user notices an error, the user can arbitrarily correct the movement route by a touch operation or the like. Then, a new reference route is registered based on the corrected travel route.

  In another embodiment, the current position may be shown superimposed on the displayed map. If the current position shown is different, the user can arbitrarily correct the current position by a touch operation or the like.

  In another embodiment, the next position may be estimated when the user starts moving from an arbitrary position on the reference route, that is, when the user starts moving from the middle of the reference route. In this case, in step S5 in the reference route management process shown in FIG. 6, the processor 30 determines whether or not the movement start position, that is, the current position of the user is on the reference route. If it is determined that the current position is on the reference route, “YES” is determined in the step S5, and the processes after the step S7 are executed. Thereby, even if the user starts moving from the middle of the reference route, the next position of the user can be estimated. Therefore, even if the user starts moving from the middle of the reference route, power consumption can be suppressed.

  In the other embodiments described above, when the user reaches the end position, even if the user starts moving from the middle of the route, the moving route at that time is registered as a new reference route. However, in such a case, a new reference route may not be registered. Further, when the user continues to move after reaching the end position and ends the movement at another position, the movement route at that time may be registered as a new reference route.

  In the present embodiment, in the processing described with reference to the flowchart, the steps are repeated at regular intervals (for example, about 1 second), but in other embodiments, the intervals are longer or shorter than the regular intervals. May be repeated.

  In the above-described embodiments, words such as “shorter” are used for a predetermined distance and the like, but “shorter than the predetermined distance” includes the meanings of “below the predetermined distance” and “less than the predetermined distance”.

  The program used in this embodiment may be stored in the HDD of the data distribution server and distributed to the mobile phone 10 via the network. Further, the storage medium may be sold or distributed in a state where a plurality of programs are stored in a storage medium such as an optical disk such as a CD, a DVD, or a BD (Blue-Ray Disk), a USB memory, and a memory card. Then, when the program downloaded through the above-described server or storage medium is installed in a mobile phone having the same configuration as that of this embodiment, the same effect as that of this embodiment can be obtained.

  The specific numerical values given in this specification are merely examples, and can be appropriately changed according to a change in product specifications.
