In addition, a function of transmitting the edited route guidance data to the terminal device 20 via the communication unit 11 is provided.

  FIG. 2 is a block diagram illustrating a configuration of the terminal device 20. The terminal device 20 corresponds to a mobile phone, a portable information terminal, a portable navigation device, a notebook computer, and other portable terminal devices, but may be a navigation-only device mounted on a car.

  The terminal device 20 includes a control device 21, an input device 22, and a display device 23.

  The communication unit 211 is an interface for communicating with the navigation server 10 via the communication network 50.

  The GPS processing unit 212 has a function as position positioning means for measuring the position of the terminal device. A well-known GPS function that receives a GPS satellite signal by a GPS receiver and measures the position (latitude and longitude) of the terminal device 20 can be applied to the GPS processing unit 212.

  The map route data acquisition unit 213 edits route search conditions input by the user via the input device 22 into data to be transmitted to the navigation server 10 and transmits the data to the navigation server 10 via the communication unit 211. A function of acquiring route guidance data transmitted from the navigation server 10 is provided. In addition, it has a function of transmitting a map data acquisition request to the navigation server 10 and acquiring map data from the navigation server 10.

  The display control unit 214 displays the guide route, the current position, and the map image from a plurality of display modes based on the positioning position measured by the GPS processing unit 212 and the route guide data and map data received from the navigation server 10. A function of displaying on the display device 23 in one corresponding display mode is provided. Note that the current position can be the predetermined position when the positioning position is route-matched to a predetermined position (for example, the closest position) on the guide route.

  A plurality of display modes for displaying a map image can be appropriately set according to specifications, designs, and the like. For example, a map mode for searching a map, a navigation mode for performing navigation, and a movement for leaving a user's movement history There is a history mode. Further, the map mode includes a plurality of modes such as a normal map display mode, a road mode in which roads are highlighted, and a railroad mode in which routes are highlighted, and the navigation mode includes, for example, a map. A plurality of modes such as a map navigation mode for displaying and guiding and a voice navigation mode for guiding only by voice without displaying a map can be provided.

  In addition, a map reference point (map center point) that serves as a reference when displaying a map is set on the map screen. In a certain display mode, the map reference point is set to be determined based on the current position. The Accordingly, when the map reference point is set at the approximate center of the map screen, the map is displayed so that the current position of the user is always located at the approximate center of the map screen. The map reference point can be set according to the specifications and design, but is preferably set so as to improve the readability and route recognition by the user. For example, in the case of map search, the map reference point May match the destination.

  When receiving an operation input from the user via the input device 22, the operation receiving unit 215 has a function of executing a predetermined process corresponding to the received operation input. For example, a display mode corresponding to the operation input is determined from a plurality of display modes, and the display control unit 214 is controlled so that a map and route guidance are displayed on the display in the determined display mode. The content of the operation input accepted by the operation accepting unit 215 can be set as appropriate according to the design and specification of the navigation, and is not particularly limited. For example, for the operation on the map (move, rotate, expand), navigation Related operations (reroute, route change, neighborhood search, traffic jam display, etc.), POI information (Point of Interest: for example, point, station, store, facility, area, SA / PA) addition, change, deletion, reference, etc. There is an operation. In addition, operations to instruct display of note information and guidance images, operations for referring to and changing various settings (volume, self-icon change, vehicle type change, speed change, etc.), various display modes (navigation, signal guidance, highway, There are arrow guidance, text guidance, station guidance, bird's-eye view, 3D) change operation, and the like.

  The erroneous operation determination unit 216 determines whether the operation input (target operation input) received by the operation reception unit 215 is an erroneous operation. Specifically, the determination can be made based on the input time of the target operation input and / or the input count of the target operation input and the no-operation time that has elapsed since the reception of the target operation input. For example, the erroneous operation determination unit 216 measures the input time of the target operation input, and determines whether or not the measured input time is within a specified input time (eg, 1 second). Further, the number of inputs of the target operation input is measured, and it is determined whether or not the measured number of inputs is equal to or less than the specified number of inputs. Also, the elapsed time of the no-operation time starting from the time when the operation receiving unit 215 receives the target operation input is measured, and whether or not the measured no-operation time exceeds a specified elapsed time (eg, 30 seconds). Determine. When the target operation input is composed of a plurality of operation inputs, the time when the last operation input is received is set as the starting point. And, when the input time of the target operation input is within the specified input time and / or when the input count of the target operation input is less than or equal to the specified input count, the no-operation time exceeds the specified elapsed time. In addition, the target operation input is determined as an erroneous operation. The specified input time, the specified number of inputs, and the specified elapsed time can be appropriately set according to specifications and design, and may be set in advance as defaults or may be set by the user himself / herself.

  When the erroneous operation determination unit 216 determines that the target operation input is an erroneous operation, the return processing unit 217 controls the display control unit 214 to return the display mode corresponding to the erroneous operation to a predetermined other display mode. . The predetermined other display mode can be set as appropriate according to the specification and design, but a display mode that does not impair the convenience of the user who is using the map or navigation is set. For example, if the map reference point is shifted from the current position due to an incorrect operation, the map reference point may be moved to the current position (or a GPS positioning point), or if navigation is stopped due to an incorrect operation, Navigation can be resumed. Details of the return processing by the return processing unit 217 will be described later.

  The input device 22 is for operation and input by a user, and includes a keyboard, buttons, and output means for performing various input operations by operating numeric keys, alphabet keys, other function keys, selection keys, and scroll keys. For example, a menu on a menu screen displayed on a display device 23 or a touch panel that performs an input operation by operating a map screen can be used. Keyboards and buttons are also called physical keys.

  The display device 23 displays a menu screen, a searched guide route, a map, and the like. When requesting a route search from the navigation server 10, the user operates the input device 22, displays a service menu screen or a predetermined input screen on the display device 23, and inputs a route search condition such as a departure place or a destination. To do. When the current position is selected as the departure place, the positioning position measured by the GPS processing unit 212 is used as the departure place. Further, the user may directly input an address or directly specify a predetermined position on the map as the current position.

  The communication network 50 is a communication line for transmitting and receiving information between the navigation server 10 and the terminal device 20. For example, it may be any of the Internet, a LAN, a dedicated line, a packet communication network, a telephone line, a corporate network, other communication lines, combinations thereof, and the like, regardless of whether they are wired or wireless.

  Next, the operation of the navigation system 1 will be described.

  FIG. 3 is a flowchart of the operation of the terminal device 20. In addition, each processing step to be described later can be executed in any order or in parallel as long as there is no contradiction in processing contents, and other steps may be added between the processing steps. . Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided into a plurality of steps for convenience can be grasped as one step.

  In step S <b> 1, the GPS processing unit 212 measures the position of the terminal device 20 at a predetermined timing (e.g., 1 second) and stores it in a memory or the like of the terminal device 20.

  In step S <b> 2, the map route data acquisition unit 213 transmits the route search condition input by the user to the navigation server 10 via the communication unit 211. The route search condition transmitted to the navigation server 10 includes information on the departure place and the destination. The departure point and the destination can be input by the user via the input device 22. When the current position is selected as the departure point, the position determined by the GPS processing unit 212 is set as the departure point. Further, when the user operates the input device 22 to input an address or a desired point on the map, the input point is used as a departure place.

  When the navigation server 10 receives the route search condition from the terminal device 20, the route search unit 13 searches the optimum route from the departure point to the destination.

  Further, the transmission data editing unit 14 edits the optimum route obtained as a result of the search into route guidance data for transmission to the terminal device 20. The route guidance data includes attribute information such as branches such as intersections (guidance points (guidance points)) on the route from the departure point to the destination. The attribute information includes the coordinates of the guidance point (latitude and longitude information), the coordinate point sequence of the route to the next guidance point (or from the previous guidance point), the road type, the name of the guidance point, and the name of the name. Travel angle information, guidance images at guidance points, guidance voice data, types of guidance points (intersections, toll gates, etc.), and the like. The transmission data editing unit 14 transmits the edited route guidance data to the terminal device 20 via the communication unit 11.

  In step S <b> 3, the map route data acquisition unit 213 of the terminal device 20 receives route guidance data from the navigation server 10 via the communication unit 211, and stores the received route guidance data in a memory or the like of the terminal device 20.

  In step S <b> 4, the map route data acquisition unit 213 transmits a map data request around the positioning position measured by the GPS processing unit 212 to the navigation server 10 via the communication unit 211.

  When the navigation server 10 receives a map data request from the terminal device 20, the navigation server 10 acquires map data around the positioning position from the storage unit 12 and transmits the map data to the terminal device 20 via the communication unit 11.

  In step S <b> 5, the map route data acquisition unit 213 of the terminal device 20 receives map data from the navigation server 10 via the communication unit 211, and stores the received map data in a memory or the like of the terminal device 20.

  In step S6, the display control unit 214 of the terminal device 20 displays a route guidance screen (navigation screen) including the guidance route, the current position, and the map image on the display device 23 in a predetermined display mode. Here, it is assumed that the predetermined display mode is a navigation mode when the map reference point matches the current position.

  In step S <b> 7, the operation reception unit 215 of the terminal device 20 determines whether any operation input has been received from the user via the input device 22. If the determination result is correct (YES), the process proceeds to step S8. If the determination result is negative (NO), the operation reception unit 215 proceeds to step S10.

  In step S8, the operation receiving unit 215 executes a predetermined process corresponding to the operation input. Specifically, a display mode corresponding to the operation input is determined, and a map and a guidance route are displayed on the display device 23 in the determined display mode. Here, a case where the received operation input is a user's erroneous operation will be described. FIG. 5 shows a state in which the display mode is changed due to an erroneous operation input received during navigation, and the navigation is stopped. As shown in the figure, the screen G1 during navigation before an erroneous operation displays a map A in which the current position P matches the map reference point Q. As a result of an erroneous operation input, the screen G2 It can be seen that the map B on which the current position P is not displayed is displayed on the map reference point Q, and the navigation is also stopped.

  In step S9, the operation accepting unit 215 executes an erroneous operation handling process. Specifically, it is determined whether or not the received operation input is an erroneous operation according to an erroneous operation determination criterion described later. If the received operation input is an erroneous operation, a predetermined return process is executed. The details of the erroneous operation handling process will be described later.

  In step S10, the terminal device 20 determines whether or not it has arrived at the destination based on the GPS positioning position. If it has arrived (YES), the process is terminated. On the other hand, if the destination has not been reached, the process proceeds to step S11.

  In step S11, the terminal device 20 determines whether it is necessary to acquire map data to be displayed on the route guidance screen. When the map data up to the destination is not acquired at once, the terminal device 20 needs to acquire the map data near the current position from the navigation server 10 through the communication network 50 until the terminal device 20 arrives at the destination. is there. If the terminal device 20 determines that it is necessary to acquire map data (YES), the terminal device 20 proceeds to step S4. If it is determined that map data acquisition is unnecessary (NO), the process proceeds to step S6.

  Next, the flow of an erroneous operation handling process (step S9 in FIG. 3) by the terminal device 20 will be described with reference to FIG.

  In step S91, the erroneous operation determination unit 216 determines whether or not the current state of the terminal device 20 is displaying a map. If the map is being displayed (YES), the process proceeds to step S92. If the map is not being displayed (NO), the convenience of map display due to an erroneous operation is not reduced, and the erroneous operation handling process is terminated. The erroneous operation determination unit 216 may determine whether or not the current state is a state such as navigation or current position display, and may determine whether or not to proceed to step S92 according to these determination results. .

  In step S92, the erroneous operation determination unit 216 determines whether or not the user's operation input (hereinafter referred to as “target operation”) received in step 7 of FIG. It is determined based on whether or not it is in a state or whether or not it is currently in a predetermined map display state. The content of the predetermined map operation or the predetermined map display can be appropriately set according to the map provided by the navigation system 1 and the content of the navigation. For example, the operation on the map (move, rotate, expand, etc. the map) , Operations related to navigation (reroute, waypoint change, neighborhood search, traffic jam display, etc.), POI information (Point of Interest: for example, point, station, store, facility, area, SA / PA) addition, change, deletion , Operations such as browsing. In addition, operations for instructing display of note information and guidance images on the map, operations for referring to and changing various settings (volume, self-icon change, vehicle type change, speed change, etc.), various display modes (navigation, signal guidance) , Highway, arrow guidance, text guidance, station guidance, bird's eye view, 3D) change operation, and the like are also included. The predetermined map operation state and map display state can be at least one of the above operation states or display states, or any combination. When the terminal device 20 is in these operation states or display states, the target operation is considered to be an operation in accordance with the user's intention, and therefore can be excluded from an erroneous operation target. The erroneous operation determination unit 216 can make the above determination by referring to a list of map operation / display states stored in a predetermined storage area, for example.

  If it is determined in step S92 that the erroneous operation determination unit 216 is not currently in the predetermined map operation / display state (NO in S92), the process proceeds to step S93, and is determined to be currently in the predetermined map operation / display state. In this case (YES in S92), it is determined that the target operation is an operation intended by the user (= not an erroneous operation), and the erroneous operation handling process is terminated.

  In step S93, the erroneous operation determination unit 216 determines whether or not the target operation is an erroneous operation based on whether or not a predetermined no-operation condition is satisfied. If it is determined that the no-operation condition is satisfied (YES), it is determined that the target operation is an erroneous operation and the process proceeds to step S94. If it is determined that the no-operation condition is not satisfied (NO), the target operation is an erroneous operation. It is determined that it is not, and the erroneous operation handling process is terminated.

  The no-operation condition can be set based on the no-operation time during which the operation receiving unit 215 has not received an operation input, and is stored in a predetermined storage area for reference by the erroneous operation determination unit 216. The no-operation time can be calculated from the time when the operation receiving unit 215 receives the target operation, for example. The operations received by the operation receiving unit 215 include an operation input via a touch panel and an operation input via a physical key.

  As a first example of the no-operation condition, the erroneous operation determination unit 216 satisfies the no-operation condition when the no-operation time after receiving the target operation exceeds a specified time (eg, 30 seconds) (YES) ), It can be determined that the operation is incorrect. For example, when the target operation is an erroneous operation, it is considered that there is little possibility that the next operation will be input.

  The no-operation condition can also be set based on the input time of the target operation, the input count of the target operation, or a combination of the input time and the input count of the target operation.

  For example, as a second example of the no-operation condition, if the target operation is performed within a specified time (eg, 1 second) and then the no-operation time exceeds the specified time (eg: 30 seconds), the target operation May be determined to satisfy the no-operation condition. For example, when the user accidentally touches the touch panel, the input time of the target operation is considered to be short.

  Further, as a third example of the no-operation condition, after the target operation is performed within a specified number of times (eg, 1 time) and within a specified time (eg: 1 second), the no-operation time is set to a specified time (eg, 30). Second), it may be determined that the target operation satisfies the no-operation condition. For example, if the user inadvertently touches the touch panel, it is considered that the number of inputs of the target operation is small and the input time is short.

  Note that the specified time and the specified number of times described above can be set as appropriate according to the specifications and design. For example, the specified time and the specified number of times may be fixedly set in advance in the terminal device 20 or arbitrarily set by the user. Also good. Further, the specified time and the specified number of times may be set differently depending on the type of operation input. The no-operation condition can be at least one of the first to third examples or any combination, and other conditions may be added.

  As an example of other conditions, the no-operation state can be determined based on the usage state of the terminal device. Specifically, it is determined whether or not an acceleration measured by an acceleration sensor (not shown) included in the terminal device 20 is equal to or less than a predetermined acceleration threshold value. It may be determined that the target operation satisfies the no-operation condition on the condition that (for example: 30 seconds) has been exceeded. For example, if the user accidentally touches the touch panel while the terminal device 20 is placed in a stationary bag or pocket placed on the desk, the terminal device 20 is considered to be stationary. Because it is. The predetermined acceleration threshold value can be set as appropriate according to the design.

  In step S94, the return processing unit 217 determines whether or not the terminal device 20 satisfies a predetermined trigger condition. If it is determined that the predetermined trigger condition is satisfied (YES), the return processing unit 217 is processed based on an erroneous operation. In order to return the display mode of the map screen to another predetermined display mode, the process proceeds to step S95. On the other hand, if it is determined that the trigger condition is not satisfied (NO), the erroneous operation handling process is ended.

  The trigger condition can set a timing suitable for returning a display mode based on an erroneous operation to another display mode, and is stored in a predetermined storage area for reference by the return processing unit 217.

  As a first example of the trigger condition, the return processing unit 217 may satisfy the trigger condition when the user approaches a guidance point on the guidance route (a predetermined guidance point where voice guidance or image guidance is performed). it can. Specifically, as a first condition for determining whether or not the user has approached the guidance point, an estimated required time (for example, 10 minutes) required to arrive at a predetermined guidance point from a reference point on the guidance route is determined. If the subtraction result obtained by subtracting the route guidance execution time from the reference point from the estimated required time is within a predetermined time threshold (for example, 5 minutes), a method for determining that the user has approached the guidance point is provided. is there. For example, when the departure point corresponds to the reference point and there are a plurality of guide points, the reference point may be a guide point immediately before the target guide point. The estimated required time is calculated based on the distance from the reference point to the guide point and the predicted moving speed. For example, the predicted moving speed allows the user to select a moving means (walking, car) or speed information (walking = slow / fast, car = light car / general car (ordinary car) / large car) when searching for a route, It can be determined based on the selected moving means and movement information. Further, the user may directly input the predicted speed information and the estimated required time. Furthermore, the estimated moving speed of the user may be calculated from the positioning position and positioning time by the GPS processing unit 212 (or the current position and positioning time on the route matched route). The route guidance execution time is the time that has elapsed with the execution of route guidance from the reference time point.

  As a second condition, an estimated arrival time (eg, 13:10) at which the user arrives at the guidance point is calculated based on the distance from the reference point to the guidance point and the predicted moving speed, and the current time Is within a predetermined time (for example, 5 minutes) from the estimated arrival time, there is a method for determining that the user has approached the guidance point. When there are a plurality of guide points, the estimated arrival time is calculated for each guide point. Note that the user may directly input the estimated arrival time.

  As a third condition, there is a method for determining whether or not the coordinates of the current position are within a predetermined distance range from the coordinates of the guide route point. Any one of the first, second, and third conditions may be adopted, or two or more may be arbitrarily combined. Since guidance during navigation is performed in order to attract the user's attention at a particularly important point on the route such as an intersection, it is desirable to have the user confirm an appropriate guidance route screen. Return processing can be performed in accordance with the timing of checking the screen.

  As a second example of the trigger condition, the return processing unit 217 can determine that the trigger condition is satisfied when the user's action (motion) is a predetermined action. Specifically, it is determined whether or not the acceleration measured by an acceleration sensor (not shown) included in the terminal device 20 is equal to or greater than a predetermined acceleration threshold value. If the determination result is positive, it is determined that the trigger condition is satisfied. To do. The predetermined acceleration threshold value can be appropriately set according to the design. According to this configuration, for example, the return process can be performed in accordance with the timing when the user takes out the terminal device 20 from the pocket or bag and uses it.

  As a third example of the trigger condition, the return processing unit 217 determines whether or not the state of the terminal device 20 has changed to a predetermined state, and if the determination result is positive, the trigger condition is satisfied. can do. For example, the predetermined state corresponds to a state in which the terminal device 20 returns from the suspended state. According to the said structure, a return process can be performed according to the timing which the terminal device 20 transfers to a use state from a non-use state.

  As a fourth example of the trigger condition, the return processing unit 217 can satisfy the trigger condition when the screen display style of the terminal device 20 is changed to a predetermined style. The predetermined style is, for example, a horizontal display style when the screen display style has a vertical screen style that displays predetermined information according to a vertical screen (vertical direction) and a horizontal screen style that displays along a horizontal screen (horizontal direction). Applicable to screen style. For example, in the case where the terminal device 20 is configured such that a pair of housings each having a display unit and an operation key can be folded via the hinge portion, and the housing having the display portion is rotatable about the hinge portion. The horizontal screen style can be used when the user rotates the display unit side casing by a predetermined angle with respect to the operation key side casing. Further, when the terminal device 20 is configured in a stick-like shape with a display unit and operation keys, the vertical screen style terminal device 20 can be used as a horizontal screen style by rotating the terminal device 20 by, for example, approximately 90 degrees to the left. Can do. For example, the map display in the navigation may be easier to operate and operate in the horizontal screen style. Therefore, the return processing unit 217 determines whether the angle measured by the angle sensor (not shown) included in the terminal device 20 is equal to or smaller than a predetermined angle threshold, and the screen style is determined when the determination result is positive. Is determined to be in the horizontal screen style. As an example in which the angle sensor is not used, when the terminal device 20 has a screen style determination function separately, the determination function can be used. The return processing unit 217 obtains screen style designation information (display direction designation information) for designating the current screen style (display direction) from the terminal device 20, and based on the obtained screen style designation information, the current screen style. May be determined to be a horizontal screen style. According to the said structure, a return process can be performed according to the screen style more suitable for navigation.

  As a fifth example of the trigger condition, the erroneous operation determination unit 216 determines whether or not a predetermined state return instruction has been input from the user, and sets the trigger condition when the determination result is correct. Can do. The predetermined state return instruction can be set as appropriate according to the design. For example, a predetermined voice input, a predetermined button is pressed a predetermined number of times (example: twice), and a map is displayed on the touch panel a predetermined number of times (example: 2). Simple operations such as touching can be set. According to the said structure, a return process can be performed according to the said user's instruction | indication, without putting an operation burden on a user.

  Further, as a sixth example of the trigger condition, the erroneous operation determination unit 216 assumes that the trigger condition is satisfied when the positioning of the position by the GPS processing unit 212 is interrupted by an erroneous operation and then the positioning is started again. be able to. According to the said structure, a return process can be performed according to the timing which can update a user's present position on a guidance route.

  The trigger condition can be at least one of the first to sixth examples or any combination.

  When the trigger condition is satisfied, in step 95, the return processing unit 217 executes return processing for returning the display mode of the map screen processed based on the erroneous operation to a predetermined display mode. The predetermined display mode can be set so that visibility to the map and the navigation is not lowered.

  As a first example of the return process, the return processing unit 217 further performs a prescribed navigation operation so that the map reference point of the currently displayed map matches the current position (position on the route matched guide route). The display mode is changed so as to be in a state (navigation operation state). For example, when the specified navigation operation state corresponds to the navigation operation state before the target operation, the navigation operation state before the target operation is being navigated, and the navigation is stopped by the target operation, The navigation can be resumed in order to return to the navigation operation state. On the other hand, if the navigation operation state before the target operation is stopped, and navigation has been executed by the target operation, the navigation can be stopped to return to the navigation operation state before the target operation. According to this configuration, even if the current position disappears from the map due to an erroneous operation, the map is automatically returned to the map with the current position as the map reference point, so that the map can be easily confirmed. Further, for example, even when the navigation is stopped due to an erroneous operation, the navigation is automatically started, so that smooth movement along the guidance route is possible.

  FIG. 5 shows a state in which the map screen returns to the display mode before navigation after the display mode is changed by an erroneous operation input received during navigation. As shown in the figure, on the screen G2 at the time of an erroneous operation, a map B that does not include the current position P is displayed, and navigation is also stopped. On the other hand, on the screen G3 after the return process is executed, the map C in which the current position P is located on the map reference point Q is displayed, and it can be seen that the navigation is resumed.

  Further, as a second example of the return processing, the return processing unit 217 displays the display mode so that the map reference point of the currently displayed map matches the GPS positioning position, and further enters the prescribed navigation operation state. To change. According to this configuration, even if the current position disappears from the map due to an erroneous operation, the map is automatically returned to the map with the GPS positioning position as the reference point, so that the map can be easily confirmed. Further, for example, even when the navigation is stopped due to an erroneous operation, the navigation is automatically started, so that smooth movement along the guidance route is possible.

  Further, as a third example of the return process, the return processing unit 217 changes the display mode so that the navigation mode of the current map screen becomes a specified navigation mode (eg, default, navigation mode before erroneous operation). When there are multiple navigation modes (for example, a map navigation mode that displays a map for guidance and a voice navigation mode that provides guidance only by voice without displaying a map), the navigation mode is changed to an unintended navigation mode by the user. Even in this case, the navigation mode can be automatically returned to the default or the navigation mode before the erroneous operation.

  As a fourth example of the return process, the return processing unit 217 changes the display mode so that the current map mode becomes a specified map mode (eg, default, map mode before erroneous operation). When there are multiple map modes (for example, a normal map, a road mode that emphasizes roads, a railroad mode that emphasizes routes), even if the map mode is not intended by the user due to an erroneous operation, the map before the default or erroneous operation You can automatically return to the mode.

  Further, as a fifth example of the restoration process, the restoration processing unit 217 changes the display mode so that the current map scale becomes a specified scale (eg, default, scale before erroneous operation). In a configuration in which the user can arbitrarily select a scale, even when the scale is changed to an unintended scale by an erroneous operation, the scale can be automatically returned to the default or the scale before the erroneous operation.

  Further, as a sixth example of the return process, the return processing unit 217 changes the display mode so that the current map rotation mode becomes a specified map rotation mode (eg, default, map rotation mode before erroneous operation). When there are a plurality of map rotation modes (for example, a mode that rotates by touching the touch panel or a mode that rotates according to the direction in which the terminal device 20 is directed), and the map rotation mode is changed to an unintended map rotation mode by the user However, it is possible to automatically return to the map rotation mode before default or erroneous operation.

  Further, as a seventh example of the return process, the return processing unit 217 changes the display mode so that the current basic setting becomes a specified basic setting (eg, default, basic setting before erroneous operation). According to this configuration, even when the basic setting is not intended by the user due to an erroneous operation, the default setting or the basic setting before the erroneous operation can be automatically restored.

  Note that the display mode that is the target of the return process is not limited to the first to seventh examples, and can be set as appropriate according to specifications, designs, and the like.

  As described above, according to the present embodiment, when an operation input is received from the user during map display, it is determined whether or not the operation input is an erroneous operation. Since the map and the navigation are restored to the display mode before the erroneous operation input, it is possible to prevent the convenience of the map display from being lowered due to an erroneous operation.

[Embodiment 2]
Embodiment 2 demonstrates the case where the terminal device 20 of Embodiment 1 is provided with a pedometer function. FIG. 6 is a block diagram illustrating a configuration of the terminal device 20. The terminal device 20 of the second embodiment is different from the terminal device 20 (FIG. 2) of the first embodiment in that a pedometer processing unit 218 is provided.

  The pedometer processing unit 218 has a step count measurement function that measures the number of steps of the user by detecting vertical vibrations of the body when the user walks. For the step counting function that measures the number of steps, for example, the number of steps is counted using a pendulum type that counts the number of steps by the movement of a pendulum attached inside the terminal device 20 or an acceleration sensor that measures a change in speed per fixed time. A well-known step count measuring technique such as an acceleration sensor type can be applied. The pedometer processing unit 218 has a walking distance calculation function for calculating a walking distance based on the measured number of steps. The walking distance can be calculated, for example, by multiplying a predetermined stride value by the number of walks measured.

  An operation flow of the terminal device 20 in the second embodiment will be described.

  The terminal device 20 provides navigation according to steps S1 to S6 of FIG. In step S7, when the operation accepting unit 215 accepts an operation input for starting to use the pedometer (YES), in step S8, the pedometer processing unit 218 is instructed to do so, and the calculation of the number of steps and the walking distance is performed. To start. When navigation is being executed, the navigation is stopped and the map display mode is changed to a non-navigation display mode.

  In step 9, the terminal device 20 executes the erroneous operation determination process shown in FIG. 4 as described above in the first embodiment. When the operation input for starting the use of the pedometer is an erroneous operation, the number of steps and the walking distance are calculated. Cancel and resume navigation.

  According to the above configuration, even when the start of pedometer use is input by mistake during navigation, the navigation is automatically resumed, so that it is possible to avoid impairing the convenience of the user.
