  Thereafter, the control unit 104 of the route search server 100 transmits route information representing the searched route to the mobile phone 200. Specifically, the route information includes information representing each point included in the route, a section ID of a section included in the route, attribute information of an intersection included in the route, and the like.

  FIG. 3 is a diagram showing the contents of route information and route data. The route data stored in the storage unit 106 of the route search server 100 includes node information, intersection attribute information, and arc information. The node information is data representing points such as an intersection, a point where the number of lanes changes on the road, a place where an approach road to the toll road branches, a start point and an end point of a curve. In FIG. 3, Nd01 to Nd11 are shown as nodes.

  The arc information is information relating to an arc that is a road between nodes. Each arc is assigned a unique ID. In the example of FIG. 3, IDs from 01 to 10 are shown as IDs assigned to each arc in order to simplify the description. Each arc information includes latitude and longitude data of a number of points included in each arc. That is, roads for which routes can be set can be represented as a sequence of points. Each arc information includes information on whether or not each arc is a toll road and information on the number of lanes in addition to the ID and point sequence information.

  The intersection attribute information is information to be displayed on the display panel 202 of the user's mobile phone 200 when the user enters the intersection. FIG. 3 shows attribute information Ndp03 to be displayed on the display panel 202 of the user's mobile phone 200 entering the intersection of the node Nd03 as an example. The attribute information Ndp03 is information indicating a road destination.

  The control unit 104 of the route search server 100 refers to the route data stored in the storage unit 106, and based on the departure point information (current position information), destination information, waypoint information, and condition information, Explore. Then, the control unit 104 generates route information representing a route from the departure point to the destination, and transmits the route information to the mobile phone 200. The route information includes node information, section information, and intersection attribute information.

  In FIG. 3, the departure place (user's current position) is indicated by Ps. The waypoints are indicated by Pv1 and Pv2. The destination is indicated by Pe. In the example of FIG. 3, it is assumed that the route R0 indicated by the broken line is searched by the control unit 104. In FIG. 3, the route R0 is indicated by a broken line. The control unit 104 includes section information of sections 01 to 04 (section ID of each section and latitude and longitude information of each point included in each section), information of nodes Nd03, Nd06, Nd09, attribute information of each node, and the like. Is transmitted to the mobile phone 200.

  The section information is information related to a section that is a road between the starting point and the first node, between the nodes, and between the last node and the destination in the searched route. Each section is assigned a unique ID. In the example of FIG. 3, IDs 01 to 04 are shown as IDs assigned to the sections.

  If the section is a road between nodes, the section information of the section is the same as the corresponding arc information (see sections 02 and 03 in FIG. 3). If the section is a road between the departure point and the node, the section information of that section is replaced with the latitude and longitude data of each point between the nodes that the corresponding arc information has, and between the departure point and the node. Data of latitude and longitude of each point (see section 01 in FIG. 3). If the section is a road between the node and the destination, the section information of the section is replaced with the latitude and longitude data of each point between the nodes of the corresponding arc information, and between the node and the destination. (See section 04 of FIG. 3).

  In step S220 of FIG. 2, the application software 212 displays the route on the display panel 202 based on the latitude and longitude information of each point included in each section received from the control unit 104 of the route search server 100. In this state, when the cursor key 206b is operated, a place corresponding to a node having attribute information to be displayed in the route guide is sequentially selected on the route. When the cursor is placed at a location corresponding to such a node (for example, the node Nd03 in FIG. 3), the attribute information is displayed.

  Note that the application software 212 periodically specifies the current position, and obtains map image data of the surroundings according to the current position from the map server 150. In step S220 of FIG. 2, the route is displayed by superimposing and displaying each point on the route obtained from the route search server 100 on the surrounding map image data obtained from the map server 150.

  When the application software 212 receives the route information from the route search server 100, the application software 212 starts a route guide process and sets a START flag indicating that the route information has been acquired to “1” in the RAM (not shown) of the main control unit 210. To do. The START flag is “0” before route information is received from the route search server 100.

  Thereafter, when an instruction to start the route guide is input via the command input unit 206, the application software 212 starts the route guide. The route guide is performed based on route information received from the route search server 100.

  While executing the route guide, the application software 212 creates passing section data based on the information of each section and the current position information. The passing section data represents a section that has been passed among the sections included in the route. That is, the passing section data includes an ID of a section that has been passed. For example, in the example of FIG. 3, when the user has reached the point Pi, the passing section data includes the ID of the section 01. When the user arrives at the destination, all sections included in the route are passed sections.

  Thereafter, in step S230, when the user, that is, the mobile phone 200 arrives at the destination, the application software 212 ends the route guide. At the same time, the application software 212 sets the START flag to “0” in the RAM (not shown) of the main control unit 210.

  On the other hand, if the user does not log in to the system for a predetermined time (for example, 24 hours), the control unit 104 of the route search server 100 then associates the session ID with the session ID in step S120. The ID, departure point information (current position information), destination information, waypoint information, and condition information are deleted from the storage unit 106.

  FIG. 4 is a chart showing operations of the application software 212 and the route search server 100 when the application software 212 is forcibly terminated and then the application software 212 is restarted and the guide is resumed.

  In FIG. 4, the operations up to step S220 are the same as those in FIG. Thereafter, in step S222, it is assumed that the application software 212 is forcibly terminated by the user. Note that “forced termination” of application software refers to an aspect in which application software is terminated by processing outside the application software, not terminated by processing inside the application software. For example, when the application software being executed is not terminated using the menu of the application software being executed, but the application software being executed is terminated by pressing the power button of the mobile phone. In such a case, the application software 212 ends while the START flag in the RAM of the main control unit 210 remains “1”.

  Thereafter, in step S224, the application software 212 is activated again by the user.

  FIG. 5 is a display on the display panel 202 that prompts an input for instructing whether or not to resume route guidance that has been interrupted in the past. When the application software 212 confirms that the START flag in the RAM of the main control unit 210 is 1 in step S 226 of FIG. 4, the screen of FIG. 5 is displayed on the display panel 202. That is, the screen of FIG. 5 is displayed when the mobile phone 200 has acquired route information in the past and has not arrived at the destination by the route guide based on the route information.

  In the screen of FIG. 5, the user selects the “Yes” button when resuming route guidance interrupted in the past. When the route guidance interrupted in the past is not resumed, the user selects the “No” button. The selection of the button is performed by pressing the left or right part of the cursor key 206b. The ON input is performed by pressing the center portion of the cursor key 206b.

  When the “No” button is selected, a screen for inputting a destination, waypoint, route search conditions, and the like is displayed on the display panel 202. The following processing is the same as that described in step S210 of FIG.

  On the other hand, when the “Yes” button is selected, the application software 212 sends a user ID, departure point information (current position information), and passing section data along with a route search request via the communication unit 205. It transmits to the search server 100. Note that destination information representing a destination, route information representing a waypoint, and condition information representing a route search condition are not transmitted.

  In step S115 of FIG. 4, the control unit 104 of the route search server 100, based on the user ID transmitted from the application software 212, the session ID associated with the user ID and the destination associated with the session ID. Information, waypoint information, and condition information are acquired from the storage unit 106. Then, the control unit 104 of the route search server 100 determines the route based on the destination information, waypoint information and condition information, departure point information (current position information) received from the mobile phone, and passage section data. Explore.

  By setting it as such an aspect, a user does not input the information (refer to step S210 of FIG. 2 and FIG. 4), such as the destination inputted in the past, a stopover, and search conditions, from the command input part 206 again, The guide can be resumed (see steps S226 and S228 in FIG. 4).

  Based on the passing section data, the control unit 104 of the route search server 100 searches for a route that does not pass through the transit point included in the passed section. For example, in the example of FIG. 3, it is assumed that the application software 212 is forcibly terminated at the point Pi and then the application software 212 is restarted at the point Pr.

  When the node Nd03 is exceeded, the application software 212 has created passing section data in which the section 01 has been passed. Therefore, the control unit 104 of the route search server 100 searches for a route R1 that does not pass through the transit point Pv1 included in the section 01 that has passed. The route R1 searched in this way is indicated by a one-dot chain line in FIG. The route R1 is a route that starts from the point Pr and reaches the destination Pe via the waypoint Pv2.

  By adopting such a mode, a route from the current position (point Pr in FIG. 3) where the application software 212 is restarted to the destination via the already set waypoint (route point Pv2 in FIG. 3). Can be set. Even when the current position at which the application software 212 is restarted is not on the previously set route, a route that goes straight from the current position to the destination is not set.

  Further, by adopting the above-described mode, it is possible to prevent a situation in which a route that has already passed and does not need to pass through again is set so as to pass through the transit point (route point Pv1 in FIG. 3) again. Can do.

  Thereafter, the control unit 104 of the route search server 100 transmits the searched route information to the mobile phone 200. The information to be transmitted is the same as the information transmitted after step S110 in FIG.

  In step S228, the application software 212 of the mobile phone 200 displays the route on the display panel 202 based on the information received from the control unit 104 of the route search server 100. Thereafter, when an instruction to start the route guide is input via the command input unit 206, the application software 212 starts the route guide. The following processing is the same as S220 and the subsequent steps in FIG.

  FIG. 6 is a diagram showing a screen displayed when the application software 212 is terminated in the middle of the guide. The case where the application software 212 is forcibly terminated during the guide has been described above (see step S226 in FIG. 4). On the other hand, when the application software 212 is terminated using the menu of the application software 212 during the guide, the screen of FIG. 6 is displayed on the display panel 202. The screen in FIG. 6 is a screen prompting an input indicating whether or not to save information on route guidance (route guide).

  When “Yes” is selected on the screen of FIG. 6 and an instruction to save the route guide is input via the command input unit 206, the application software 212 saves the information about saving the route guide. The instruction information is transmitted to the route search server 100 together with the user ID. When receiving the save instruction information via the communication unit 102, the control unit 104 of the route search server 100 is associated with the session ID associated with the user ID and the session ID even after the end of the route guide. The destination information, the waypoint information, and the condition information are stored in the storage unit 106. Further, the application software 212 keeps the START flag in the RAM as “1”.

  On the other hand, when “No” is selected on the screen of FIG. 6 and an instruction not to save the route guide is input via the command input unit 206, the application software 212 does not need to save information about the route guide. Is transmitted to the route search server 100 together with the user ID. When the non-saving instruction information is received via the communication unit 102, the control unit 104 of the route search server 100 stores the session associated with the user ID stored in the storage unit 106 after the end of the route guide. The destination information, waypoint information, and condition information associated with the ID and session ID are discarded. Further, the application software 212 sets the START flag in the RAM to “0”.

  According to such an aspect, when the user does not need information on route guidance, the information on the route guide can be discarded when the route guide ends, and the capacity of the storage unit 106 can be effectively utilized.

  Further, in order to rewrite the START flag in accordance with an instruction from the user as to whether or not to save information on route guidance (route guidance), when the application software 212 is subsequently started, the screen of FIG. 5 is not displayed. A screen that prompts input of destination, waypoint, route search conditions, and the like can be displayed.

A3. Screen display and operation:
7 to 10 are diagrams showing the relationship between the orientation (posture) of the mobile phone 200 with respect to the vertical direction and the orientations of the map images Mp01 to Mp04 displayed on the display panel 202 of the mobile phone 200. FIG. 7-10, the arrow U represents the vertically upward direction. However, since the paper surface is two-dimensional, the actual vertical upward direction represented by the arrow U in the paper surface can take a range of greater than 0 and smaller than 180 degrees within the surface that includes the arrow U and is perpendicular to the paper surface.

  In the vicinity of the arrow U, a symbol Dc for describing another direction with respect to the direction of the arrow U is described. The line segments with numerals 3, 6, 9, and 12 included in the symbol Dc are the 3 o'clock direction, 6 o'clock direction, 9 o'clock direction when the direction of the arrow U is the 12 o'clock direction, Represents the 12 o'clock direction. In addition, the middle line segments to which the numbers 3, 6, 9, and 12 are attached are in the direction of 1:30 and 4:30, respectively, when the direction of the arrow U is set to 12:00. Orientation, 7:30 direction, 10:30 direction. Each line segment divides 360 degrees at an equal angle.

  7 to 10, an arrow Cu indicates “above the mobile phone 200”. Note that “above the mobile phone 200” is a direction defined for convenience in order to describe the attitude of the mobile phone 200. “Upward of the mobile phone 200” is the direction in which the user is most likely to hold the mobile phone 200 face up. For example, “above mobile phone 200” is a direction that coincides with at least one of the characters of the carrier name and the maker name written on the surface on which the display panel 202 is provided.

  In the state of FIG. 7, the upper Cu of the mobile phone 200 is the 12 o'clock direction when the direction of the arrow U is 12 o'clock. In the state of FIG. 8, the upper Cu of the mobile phone 200 is also in the 3 o'clock direction. In the state of FIG. 9, the upper Cu of the mobile phone 200 is also in the 6 o'clock direction. In the state of FIG. 10, the upper Cu of the mobile phone 200 is also in the 9 o'clock direction. However, in any state of FIGS. 7 to 10, the map image is displayed on the display panel 202 so that the direction of the arrow U is upward. It is assumed that “upward” of the map is the direction that matches the uppermost of the characters included in the map.

  The cursor key 206b is a circular button and has eight operation portions evenly along the outer periphery of the circle. Here, among the eight operation portions, the operation portion that is the uppermost along the vertical direction (see arrow U) is referred to as “upper operation portion P1”. Of the eight operation parts, the operation part located at the lowermost position in the vertical direction is referred to as “lower operation part P2”.

  When the direction of the upper operation portion P1 is 12 o'clock and the direction of the lower operation portion P2 is 6 o'clock, facing the cursor key 206b, the operation portion positioned at the 3 o'clock direction is indicated as “right operation portion”. Called “P3”. Similarly, an operation part located in the 9 o'clock direction is referred to as a “left operation part P4”. In the present embodiment, each direction when the direction of the upper operation portion P1 is 12 o'clock and the direction of the lower operation portion P2 is 6 o'clock is directly opposite to the cursor key 206b, and the direction indicated by the symbol Dc Matches.

  Similarly, the operation part located in the direction of 1:30 is called “upper right operation part P5”. The operation part located in the 4:30 direction is referred to as “lower right operation part P6”. The operation part located in the 7:30 direction is referred to as “lower left operation part P7”. The operation part located in the direction of 10:30 is referred to as “upper left operation part P8”. The names of the respective operation parts are relative names that change depending on the posture of the mobile phone 200 with respect to the vertically upward direction (see FIGS. 7 to 10).

  When the “upper operation portion P1” is pressed, the map images Mp01 to Mp04 move in the 12 o'clock direction indicated by the symbol Dc regardless of the posture of the mobile phone 200 (see FIGS. 7 to 10). When the “lower operation part P2” is pressed, the map image moves in the 6 o'clock direction regardless of the posture of the mobile phone 200. When the “right operation part P3” is pressed, the map image moves in the 3 o'clock direction regardless of the posture of the mobile phone 200. When the “left operation portion P4” is pressed, the map image moves in the 9 o'clock direction regardless of the posture of the mobile phone 200.

  When the “upper right operation part P5” is pressed, the map images Mp01 to Mp04 move in the direction of 1:30 indicated by the symbol Dc regardless of the posture of the mobile phone 200. When the “lower right operation part P6” is pressed, the map image moves in the direction of 4:30 regardless of the posture of the mobile phone 200. When the “lower left operation portion P7” is pressed, the map image moves in the direction of 7:30 regardless of the posture of the mobile phone 200. When the “upper left operation portion P8” is pressed, the map image moves in the direction of 10:30 indicated by the symbol Dc regardless of the posture of the mobile phone 200.

  In FIGS. 7 to 10, as indicated by an arrow Ar1, for example, when the finger is slid clockwise with the outer peripheral portion of the cursor key 206b being pressed, the map is displayed in an enlarged manner. Further, as indicated by an arrow Ar2, for example, when the finger is slid in the counterclockwise direction while pressing the outer peripheral portion of the cursor key 206b, the map is displayed in a reduced size.

  In other words, in this embodiment, the image enlargement and reduction operations can be performed by a rotation operation. For this reason, the user can enlarge or reduce the map by the same operation regardless of the orientation of the mobile phone 200.

  FIGS. 11 to 14 are views showing the relationship between the orientation (posture) of the mobile phone 200 with respect to the vertical direction and the orientations of the operation menus M01 and M02 displayed on the display panel 202 of the mobile phone 200. FIG. 11 to 14, notations other than the operation menus M01 and M02 are the same as those in FIGS. 7 to 10.

  When the portion 200b having the display unit 202 and the cursor key 206a of the mobile phone is slid with respect to the portion 200a having the numeric key 206b to expose the numeric key 206b, the menu M01 shown in FIGS. 11 to 14 is automatically displayed. The

  In the mobile phone 200 of this embodiment, the numeric keypad 206a can be operated in the open state. On the other hand, in the cellular phone 200 of this embodiment, the cursor key 206b can be operated in the closed state, but the numeric keypad 206a cannot be operated. For this reason, when the user opens the mobile phone 200, in many cases, the user desires to input characters for operations such as searching for a destination.

  In this embodiment, the menu is automatically displayed when shifting from the closed state to the open state. For this reason, it is not necessary for the user to give an instruction for displaying the menu. Therefore, the convenience of the user who tries to input characters is high.

  11 to 14, option “1” is selected from the operation menu M01. As a result, of the operation menu M01, the operation menu M02 that is a submenu of the option “1” is displayed. 11 to 14, option “1” is selected from the operation menu M02. The selected option is indicated by a double line in FIGS.

  As shown in FIGS. 11 to 14, in any state of FIGS. 11 to 14, the operation menus M01 and M02 are displayed on the display panel 202 so that the direction of the arrow U is upward. The “upward” of the menu is the direction that matches the upper side of the characters included in the menu.

  When the “upper operation portion P1” is pressed, the option specified by the user among the options arranged in the direction specified at 12 o'clock and 6 o'clock is indicated by the symbol Dc regardless of the attitude of the mobile phone 200. Move in the direction of time. Similarly, when the “lower operation part P2” is pressed, the designated option moves in the 6 o'clock direction regardless of the posture of the mobile phone 200. In the state shown in FIGS. 11 to 14, by operating the upper operation part P1 and the lower operation part P2, the options 1 to 3 of the operation menu M02 can be designated.

  When the “right operation portion P3” is pressed, the option specified by the user among the options arranged in the direction specified at 9 o'clock and 3 o'clock is the 3 indicated by the symbol Dc regardless of the attitude of the mobile phone 200. Move in the direction of time. Similarly, when “left operation portion P4” is pressed, the designated option moves in the 9 o'clock direction regardless of the posture of the mobile phone 200.

  In the state of FIGS. 11 to 14, one option of the operation menu M02 and one option of the operation menu M01 can be designated by operating the right operation part P3 and the left operation part P4. As a result, a mode in which 1 to 3 options of the operation menu M02 can be designated by the upper operation part P1 and the lower operation part P2, and 1 to 8 options of the operation menu M01 by the upper operation part P1 and the lower operation part P2. The mode in which can be specified can be specified.

By setting it as such an aspect, the map image and the image of the operation menu can be displayed according to the vertical upward direction. While performing the modification of such a display method, the operation of the screen by the cursor keys 206b is Ru performed based on the relative positions of the operation portion for vertically upward.

  In FIGS. 11 to 14, as indicated by an arrow Ar <b> 1, when the finger is slid clockwise with the outer peripheral portion of the cursor key 206 b pressed, for example, 12 o'clock and 6 o'clock in the menu. The image representing the option specified by the user among the options lined up in the direction specified by is moved in the 6 o'clock direction. Also, as indicated by an arrow Ar2, for example, when the finger is slid in the counterclockwise direction while pressing the outer peripheral portion of the cursor key 206b, the direction specified at 12 o'clock and 6 o'clock in the menu The image representing the option specified by the user among the lined options moves in the 12 o'clock direction.

  That is, in this embodiment, the operation for changing the designated option can be performed by a rotation operation. For this reason, the user can change the option specified by the same operation regardless of the orientation of the mobile phone 200.

  In the mobile phone 200 of this embodiment, the numeric keypad 206a can be operated in the open state. On the other hand, in the cellular phone 200 of this embodiment, the cursor key 206b can be operated in the closed state, but the numeric keypad 206a cannot be operated. For this reason, when a user opens the mobile phone 200, in many cases, the user desires to input characters.

  In the present embodiment, when the mobile phone 200 is in the closed state, the rotating operation of sliding while pressing the cursor key 206b is an instruction for designating the enlargement and reduction of the map. On the other hand, when the mobile phone 200 is in the open state, the rotating operation of sliding while pressing the cursor key 206b is an instruction to specify the change of the option in the menu. That is, according to the present embodiment, different instruction contents that are highly likely to be desired by the user in the open state and the closed state are assigned to the same operation. For this reason, the convenience of the user when performing route guidance with the mobile phone 200 is high.

B. Variations:
The present invention is not limited to the above-described examples and embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

B1. Modification 1:
In the above embodiment, the route search server 100 searches for a route based on the stored destination information, waypoint information, and condition information even when the guide is resumed (step of FIG. 4). (See S115). However, all route information of the route searched in step S110 is stored in the storage unit 106 in association with the session ID, and when the guide is resumed, the route information may be transmitted to the mobile phone 200. it can. If it is set as such an aspect, the waiting time of the user at the time of resuming a guide can be shortened.

  It is also possible to adopt a mode in which part of the route information is stored instead of storing all of the route information. For example, for the route, the section ID and arc ID may be stored without storing the latitude and longitude information of each point included in the section.

  Further, in the above embodiment, when “Yes” is selected on the screen of FIG. 6, the destination information, waypoint information, and condition information are stored in the storage unit 106 of the route search server 100. However, destination information, waypoint information, condition information, route information, or a part of them can also be stored in a recording medium such as a RAM of the mobile phone 200.

B2. Modification 2:
In the above embodiment, the START flag is changed from “0” to “1” when the route information is received from the route search server 100. However, when the route guide is started, the START flag can be changed from “0” to “1”, that is, in the ON state. In such an aspect, when the user does not actually use the route guide, a screen (see FIG. 5) that prompts the user to input whether or not to restart the route guide is displayed when the application software is subsequently started. .

  Therefore, when searching for a plurality of routes in a state where there is no plan to perform a guide immediately afterwards, the user is not required to perform an operation for confirming the intention to resume the guide, and the burden on the user is small.

B3. Modification 3:
In the above embodiment, when the cursor key 206b is operated clockwise, the map is enlarged or moved from the selected top specified in the menu to the bottom. When the cursor key 206b is operated counterclockwise, the map is displayed in a reduced size or moved from the selected bottom specified in the menu to the top. In this operation, the same function can be instructed not only when a circular arc or a curved line is drawn while the cursor key 206b is pressed, but also when sliding with a combination of straight lines such as a polygonal side. it can.

  That is, in the input means that can input different information by operating different parts, by pressing the second part among the first part and the second part surrounding the first part, By moving the pressing position in the clockwise direction, the first processing relating to the image can be performed. And the 2nd process regarding an image can be performed by moving a press position counterclockwise. Here, the second process is performed by performing the first process for the image by the first predetermined amount, and then performing the second process for the image by the second predetermined amount. This is a predetermined process that can return the image to the state before the first process. Note that the first predetermined amount and the second predetermined amount may be the same or different.

  Note that “the second part surrounds the first part” means a state in which an arbitrary point included in the first part is an internal dividing point of two points included in the second part. . In addition, the clockwise operation and the counterclockwise operation may use any place as a start point and any place as an end point.

  Further, in the case of describing “clockwise” and “counterclockwise”, the determination of “clockwise” or “counterclockwise” can be made by inputting “different information by operating different parts”. The center of the “input unit” is determined to be the center of the watch.

B4. Modification 4:
In the above embodiment, when a user inputs any instruction, processing corresponding to the instruction is performed (see FIGS. 5 and 6). However, it is also possible to adopt a mode in which one of the options is processed when an instruction is not input for a predetermined time after the user is presented with the option. For example, if the user selects neither “Yes” nor “No” for one minute after displaying the screen of FIG. 6, the same processing as when “Yes” is selected may be executed. preferable.
