Description

  The present invention relates to a mobile terminal device and a control method thereof, and more particularly to a technique for presenting walking navigation information corresponding to an operation situation when a user carrying the mobile terminal device is operating a terminal during walking.

Conventionally, a car navigation system for displaying and guiding a route in an automobile or the like is often used. In the car navigation system, when a destination is input, a route is searched, and not only the route but also the required time to the destination in consideration of road conditions is notified to the user. Outside the automobile field, there are systems for mobile communication terminals that inform pedestrians of the route to the destination, the current position, and the required time. Further, a technique for acquiring a standard walking speed of a pedestrian and notifying the user of how much it needs to hurry if it is determined that the walking speed is not in time for the desired arrival time (see Patent Documents 1 and 2). Is also disclosed.

It is possible to guide to arrive. The risk of falls and collisions can be further reduced by making the amount of rushing when browsing or creating an email less than with a normal guide.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
<Example 1>
FIG. 1 is a block diagram showing a basic configuration of a mobile terminal device according to the present invention. As shown in the figure, the mobile terminal device 1 according to the present invention includes a position acquisition means (GPS function) 2, a destination setting means 3, a route determination means 4, an operation status detection means 5, a storage means 6, a notification means 7, and The customizing means 8 is provided. The mobile terminal device 1 further includes a control unit (CPU) CC that controls the operation of the entire mobile terminal device, an input unit IF such as a key, a button, and a microphone, and an output unit OF such as a display and a speaker. The position acquisition means 2 measures the current position of the portable terminal device carried by the user and displays the current position on the display (one function of OF). The destination setting means 3 prompts the user to select a destination on the display, and the route determination means 4 determines the optimal walking route from the current position to the destination, thereby determining the destination from the current position. The required distance to the ground is determined.

  The operation status detection means 5 obtains the operation status of the own terminal from the control means CC. The control means CC has various terminal operation-related information (for example, a flag during a call, a mail being viewed, etc.) stored in a control block in a mail-related program, a web-related program, or an operating system. Flags such as flag and mail input) are passed to the operation status detection means 5 as the operation status. Furthermore, the control means CC also passes the input status of the input means IF (key input, etc.) and the output status of the output means OF (web display, mail display, etc.) to the operation status detection means 5 as the operation status.

  The notification means 7 searches the walking influence table 6A classified by operation situation stored in the storage means 6 using the detected operation situation (OP1, OP2, OP3, etc. in the figure) as a search key, and reads the corresponding walking influence information. . For example, when browsing a mail or the web, walking influence information indicating that easiness of walking (that is, the standard walking speed and the maximum walking speed) is reduced by 10% is obtained by searching with OP1. Similarly, when making a call, searching for OP2 gives walking influence information indicating that walking ease (walking speed) increases by 5%. When inputting characters, OP3 The walking influence information indicating that the ease of walking (walking speed) is reduced by 20% is obtained by searching with. The notification means 7 calculates the user's predicted walking speed, predicted arrival time, etc. in the detected operation situation using the following formula and calculation means, and notifies the user of them as walking navigation information. Alternatively, a calculation means for calculating the walking navigation information may be provided separately from the notification means.

Expected walking speed = user standard walking speed × (1- (operation status OP3: influence of character input 0.1))
= User standard walking speed x 0.8
Expected arrival time = current time + expected time
= Current time + set route distance / expected walking speed As described above, when the user is inputting characters, it is estimated that the walking speed is 80% of the user's normal walking speed, and the normal [1 / 0.8] times required time is automatically calculated, and walking navigation information based on this is provided to the user.

  The operation situation-specific walking influence table 6A sets in advance typical operation situation items and standard walking influence information (default values) corresponding thereto. Note that the present invention does not necessarily require a walking influence table for each operation situation in which appropriate values and items are defined. Since the terminal according to the present invention has the customizing means 8 for learning the influence on walking when the operation is executed, the walking influence information is measured for each operation situation, and the operation is performed. Because it is possible to build a walking influence table by operation situation that “fits the user”, it is possible to customize the table with customization means 8 without having to build a table with complete numerical values and items in advance. Can provide walking navigation information adapted to the user. When the user 16 activates the customization means (function) 8 when he / she walks, the memory of the operation status and speed accumulates. Based on this customized memory, the “standard speed and the maximum speed” in each operation situation, etc. Infer. However, in the initial state, the influence information corresponding to the operation state in the memory is insufficient, and it is preferable to use the default value for estimating the speed as a supplement to the memory of the actual walking of the user 16. In the example of the figure, the influence is obtained by treating the standard walking speed and the maximum walking speed in the same row, but the influence may be set for each of the standard walking speed and the maximum walking speed.

<Example 2>
An embodiment in which the present invention is applied to a mobile phone terminal most popular as a mobile terminal device will be described. FIG. 2 is a block diagram of a mobile terminal (mobile phone terminal) to which the present invention is applied. As shown in the figure, the portable terminal 44 according to the present invention includes a position acquisition unit 15 that acquires the current position, a time acquisition unit 14 that acquires the current time, a destination that the user 16 wants to move, and a route to the destination. , And movement condition setting means 13 for setting movement conditions such as desired arrival time, the current position acquired by the position acquisition means 15, the current time acquired by the time acquisition means 14, and the movement set by the movement condition setting means 13 Based on the conditions, the necessary walking speed determining means 12 for determining an appropriate walking speed for arriving at the destination by the desired arrival time, and the necessary walking speed for the user 16 based on the necessary walking speed determining means 12 are determined. Walking guide means 10 for informing.

  The mobile terminal 44 further determines whether or not the movement condition can be achieved by comparing the maximum walking speed based on the maximum walking speed estimation means 20 and the required walking speed based on the required walking speed determination means 12. An achievement determination means 19, a walking speed acquisition means 28 for acquiring the walking speed of the user 16, a weather information acquisition means 21 for acquiring weather information, and a walking interval acquisition means 24 for acquiring the walking interval of the user 16 are provided.

  The portable terminal 44 further includes standard walking speed estimation means 26 for estimating the standard walking speed of the user 16 based on the past walking speed acquired by the walking speed acquisition means 28, and similarly, the user 16 based on the past walking speed. The maximum walking speed estimating means 20 for estimating the maximum walking speed and the communication means 22 for communicating with the outside (a server on the Internet 18) are provided.

  The required walking speed determining means 12 is the current position acquired by the position acquiring means 15 and the current time acquired by the time acquiring means 14 according to the moving conditions set by the moving condition setting means 13 until the desired arrival time at the destination. Calculate the speed required to arrive.

  The portable terminal 44 includes control means (CPU) CC that controls the operation of the whole portable terminal, input means IF such as keys, buttons, and microphones, output means OF such as displays, speakers, vibrators, and indicator lamps, and mobile phone state detection means 30. The terminal operation influence estimating means 31, the mail time estimating means 32, and the mail speed acquiring means 33 are further provided. The walking guide means 10 gives walking navigation information to the user 16 using at least one function included in the output means OF. The control means CC passes various terminal operation-related information stored in the control block etc. to the mobile phone state detection means 30 as operation status information. Furthermore, the control means CC passes the input status of the input means IF and the output status of the output means OF to the mobile phone status detection means 30 as operation status information.

  The mobile phone state detection means 30 detects the type of function such as currently operating mail, telephone call, software application, etc. based on the operation status information given from the control means CC. Also, whether the user is currently operating is detected based on whether the cellular phone is open or whether an operation such as button input is performed.

  The terminal operation influence estimation unit 31 is configured to calculate the difference between the first estimated maximum walking speed obtained by the maximum walking speed estimation unit 20 and the actual maximum walking speed for each operation situation obtained by the mobile phone state detection unit 30, the standard walking speed The difference between the first estimated standard walking speed obtained by the estimating means 26 and the actual standard speed is stored. At the time of walking guide, a decrease in speed (operation influence degree) in the current operation status of the terminal obtained by the mobile phone state detection means 30 is estimated from the memory. The first estimated maximum walking speed obtained by the maximum walking speed estimation means 20 is reduced by the operation influence degree (second estimated maximum walking speed) and passed to the movement condition achievement determination means 19. In addition, the first estimated standard walking speed obtained by the standard walking speed estimating means 26 is also reduced by the operation influence degree (second estimated maximum walking speed) and passed to the walking guide means 10.

  The mail time estimation means 32 estimates the time required for mail creation and browsing and mail speed acquisition means for obtaining a speed necessary for reading or writing one character in the creation and browsing of mail. The mail speed acquisition means 33 counts the number of characters in the mail that has been viewed or created. It also counts the time that a single email is viewed or created. In two incoming or outgoing emails, the time difference is divided by the difference in the number of characters in the body to calculate the time for one character (assuming that this is not done for emails with attachments). In addition, statistics on the number of characters of mail at the time of mail creation are taken, and the standard number of characters per mail is acquired.

  The mail time estimation means 32 acquires a predetermined number of times for one character from the mail speed acquisition means 33, and calculates and stores a standard time based on respective statistics at the time of mail browsing and mail creation. The operation status is acquired from the mobile phone state detection means, and the time for mail viewing or creation is estimated in the case of mail viewing or mail creation. In the case of mail browsing, it is estimated how long it will take to browse based on the number of characters of the mail being browsed, the browsing start time, and the time taken to read one letter. In the case of mail creation, the standard number of characters is the number of characters planned to be written in the mail, and the remaining number of characters is estimated. In the case of a reply mail, the number of characters of the reply source mail is set to the number of characters scheduled to be written in the mail, and the remaining number of characters is estimated. Estimate the time it takes to create an email by multiplying the estimated number of remaining characters by the time it takes for one character.

  The mail time estimation means 32 also stores a predetermined amount of time, how long the mail has been viewed and created, and when the mail has been sent and received. If it can be determined that mail transmission / reception continues repeatedly based on the previous period memory, the average of the time interval for sending and receiving each time within a given time period, and the average time for mail creation and mail browsing Calculate and memorize. If the transmission / reception of the mail is repeated during the walking guide, the time interval and the average of the time for reading and creating the mail are passed to the walking guide means.

  The weather information acquisition means 21 includes a weather influence speed estimation means, and the weather influence speed estimation means stores a combination of weather information and a walking speed, and the weather influence speed based on the storage and the weather information at the time of estimation. Is estimated. In the weather information, the three items of “rainfall, wind speed, and temperature” are each divided by a certain value, and the average of the maximum walking speed at that value is calculated. Multiply the value in the difference between the average maximum walking speed and the highest average maximum walking speed in the current weather information range to obtain the speed that affects the estimated maximum walking speed due to the weather. The various speeds corrected with the weather information in this way are given to the terminal operation influence estimating means 31 and the like, and are used as a basis for the walking navigation information considering the weather information.

  When it is notified from the movement condition achievement determination means 19 that the movement condition can be achieved, the walking guide means 10 notifies the user of the speed necessary to arrive at the desired arrival time. At the time of mail operation, the time required for mail creation or browsing obtained by the mail time estimation means 32, the required walking speed, the first estimated maximum walking speed, the first estimated standard walking speed, the second estimated maximum walking speed, the second estimated Based on the standard walking speed, an appropriate speed at the time of mail creation or browsing is estimated and communicated to the user. If the movement condition achievement determination means 19 informs the user that the desired arrival time can be reached if the mobile operation is terminated, the user is instructed to terminate the operation of the mobile phone. The necessary walking speed is also reported. Also, if the mobile condition achievement determination means 19 does not keep up with the mobile phone even if it is not operating, it informs the user that it is not in time for the desired arrival time.

  The movement condition achievement determination means 19 compares the second estimated maximum walking speed obtained by the terminal operation influence estimation means 31 with the necessary walking speed obtained by the necessary walking speed determination means 12. If the required walking speed exceeds the second estimated maximum walking speed, it is determined that it is impossible to arrive at the destination at the desired arrival time in this state, and it is determined that the moving condition cannot be achieved. Tell the guide means 10. At this time, if the operation influence degree obtained by the terminal operation influence estimation means 31 is 0, or the required walking speed exceeds the speed when the second estimated maximum walking speed is increased and restored by the amount reduced by the operation influence degree. In this case, the walking guide means 10 is informed that it is determined that the moving condition is absolutely unachievable. If the required walking speed is lower than the speed that increased the second estimated maximum walking speed by the amount decreased by the operation influence level and returned to the original speed, the movement condition can not be achieved unless the terminal operation is interrupted or terminated. Tell the walking guide means 10.

  The walking guide means 10 notifies the user of the required walking speed when the required walking speed obtained by the required walking speed determination means 12 exceeds the current walking speed. In addition, if the movement condition achievement determination means 19 reports that it is impossible to arrive at the destination at the desired arrival time, the user is notified that it is not in time. If it is reported that it is impossible to arrive at the desired arrival time unless the operation of the terminal is interrupted or terminated, the user is notified to terminate the operation and the necessary walking speed is also communicated. At the current speed, it calculates how much time is required to walk at the maximum speed when the terminal is not operated, and notifies the previous time by playing a display / audio. When the required walking speed is notified, the notification of the required walking speed is stopped when the second estimated standard walking speed exceeds the required walking speed. As described above, it is possible to reduce the risk of a user's falling, collision, etc. by requesting a speed exceeding the maximum walking speed at the time of operating the mobile terminal, and whether it is in time for the desired arrival time even when operating the mobile terminal Appropriate discrimination is also possible. In addition, it is possible to prevent a situation in which the mobile terminal is operated and the desired arrival time is not met.

The route estimation means 13A for estimating the destination and route to be reached and the time at which the destination is desired to be arrived based on the determined time, and confirming with the user 16 whether the route estimated by the route estimation means 13A is acceptable. When the estimated route is not approved, the route registration means 13B accepts a change operation from the user 16 and finalizes the route.

  The route estimation means 13A always stores a combination of position information and time. Of the stored location information and time, the current location of the alarm time is used as a departure point, and the alarm time is used as a reference to take out a series of places that frequently walk in the same direction. A place where walking ends, such as a place that does not move for a certain period of time or a transportation stop, is set as a destination, and a series of places from the starting point to the destination is set as a route. Based on the speed and the time required to reach the destination, the distance to the destination at several points in the route is also calculated. If the time passing through each point is close each time, the standard time (estimated time of arrival) at the last place (destination) of the route is also taken out.

  The route registration unit 13B displays the route estimated by the route estimation unit 13A and the time of the destination, and allows the user 16 to confirm and register. Further, the route is displayed to the user 16, and the selected route and the time at the destination are registered.

  FIG. 4 is a diagram illustrating an example of a data format of route information used in the terminal. The route information estimated by the route estimation unit 13A and registered by the route registration unit 13B includes, as shown in the figure, “location information of destination and name (if any)”, “departure location” Location information, name (if any), desired arrival time, distance from departure location to destination, and location information (latitude and longitude) at several points in the route "Distance to destination" and "Road conditions such as traffic lights and stairs". The above one block of route information is transferred from the movement condition setting means 13 to the necessary walking speed determination means 12 as a movement condition.

As shown in the figure, the walking guide means 10 includes a necessary walking interval calculation means 10A for calculating a walking interval necessary for walking at the necessary walking speed obtained by the necessary walking speed determination means 12, and a necessary walking speed for the user 16. Based on the determination result of the notification determination means 10C and the notification determination means 10C for determining the start and end of the notification and the content to be notified, it is determined that the required walking interval obtained by the required walking interval calculation means 10A or not in time The notification means 10B is configured to notify the user 16 of the fact by the vibration, sound or display.

  The required walking interval calculation means 10A calculates the current stride based on the current walking interval obtained by the walking interval acquisition means 24 and the walking speed obtained by the walking speed acquisition means 28, and sends the required walking speed determination means 12 to The necessary walking speed obtained in this way is divided by the step length, and the walking interval necessary for walking at the necessary walking speed with the current step length is calculated.

  The notification determination means 10C compares the current walking speed obtained by the walking speed acquisition means 28 with the required walking speed obtained by the required walking speed determination means 12, and when the required walking speed exceeds the current walking speed, the notification means 10B Is instructed to notify the necessary speed. The notification determination unit 10C further includes the standard walking speed obtained by the standard walking speed estimation unit 26 and the necessary walking obtained by the necessary walking speed determination unit 12 in a state where the notification unit 10B reports the necessary walking speed. The speeds are compared, and if the standard walking speed exceeds the required walking speed, the notification means 10B is instructed to stop the notification of the required speed.

  The notification determination unit 10C further determines that the user 16 has stopped walking due to the walking speed obtained by the walking speed acquisition unit 28, and the standard walking speed obtained by the standard walking speed estimation unit 26, The required walking speed obtained by the required walking speed determining means 12 is compared, and when the required walking speed exceeds the standard walking speed, the notification means 10B is instructed to notify the required speed. Further, the notification determination unit 10C instructs the user 16 to notify the user 16 that the determination is not in time for the notification unit 10B when the movement condition achievement determination unit 19 determines that the movement condition cannot be achieved.

When the mail is not being viewed or created, nothing is reported to the notification content determination means. When all of r1, r2, and r3 exceed the maximum walking speed, it is passed to the notification content determination means that it is impossible to obtain an appropriate speed.

  The notification content determination unit 10D determines that no notification is made when the required walking speed is lower than the current walking speed. When the necessary walking speed exceeds the current walking speed and is notified from the movement condition achievement determination means that it can be achieved, the necessary walking speed is transmitted. When the movement condition achievement determination means 19 receives a determination that the portable operation is not continued in time, a message prompting to end the operation and a necessary walking speed are transmitted. In addition, when it is determined that the mobile phone is not operated even at the normal maximum speed, it is determined that the mobile phone is not in time for the desired arrival time. However, when the mail is being viewed or created, an appropriate speed at the time of mail creation or mail viewing obtained by the mail speed calculation means 10E is transmitted. When mail transmission / reception is repeated, the appropriate speeds at the time of mail creation, mail browsing, and normal time obtained by the mail speed calculation means are transmitted. Even if the movement condition achievement judging means 19 gives a judgment that it is not in time to continue the portable operation, only an appropriate speed is transmitted if it is within the estimated time for creating or browsing the mail. If the estimated time for mail creation or browsing is exceeded, processing is performed when mail is not viewed or created.

  When it is impossible to obtain an appropriate walking speed at the time of e-mail in the e-mail speed calculation means 10E, a message prompting to end the operation and a necessary walking speed are transmitted. In addition, if the movement condition achievement determination means 19 determines that the mobile phone is not operated even at the normal maximum speed when it is not in time, it is notified that it has been determined that the desired arrival time is not in time. As described above, it is possible to allocate an appropriate speed both when browsing or creating a mail and thereafter, and it is easy for the user to browse or create a mail during the walking guide.

  FIG. 7 is a schematic diagram illustrating an example of calculation of the number of characters of mail in the mail speed acquisition unit 33. In this schematic diagram, the time required to read one character of the body (0.07 seconds) and the other time (1 second) are calculated based on the number of characters and the viewing time in two patterns of received mail. The mail speed acquisition means 33 counts the browsing time of mail that has been read for the first time and that has no attached mail out of the received mail. Count the time and the number of characters for two emails, and calculate how much browsing time will increase for each additional character based on the difference between the two emails. Similarly, the email speed acquisition means 33 counts the time used to create the email and the number of characters in the body, and calculates how much the creation time increases for each additional character based on the difference between the two emails. To do. However, at the time of creation, it is assumed that the creation is interrupted and the edited mail is not used again.

  The mail time estimation means 32 stores a predetermined number of required input times per character obtained by the mail speed acquisition means, and calculates a standard time per character by averaging this. Further, the number of characters to be browsed and the number of characters to be written in the body of the mail to be created are estimated based on the number of remaining characters in the operation status obtained by the mobile phone state detecting means and the number of characters of the reply source mail. Based on the standard time per character and the number of remaining characters, the time expected to be used for browsing and creating mail is estimated and passed to the walking guide means. With the above processing, it is possible to estimate the time used for reading or creating mail, and a walking guide suitable for reading or creating mail is possible.

  FIG. 8 is a flowchart showing the flow of processing of the walking guide. As shown in the figure, steps S1 and S2 are repeated, and the current location is continuously acquired from a predetermined time before the desired arrival time. If you know that you have left the departure point based on the acquired current location information (step S2), the basic speed before taking into account the terminal operation status, the first estimated standard walking speed and the first estimated maximum walking speed Estimation is performed (steps S3 and S4). This basic speed is preferably set by referring to a table storing the standard speed of the user customized for the user using the terminal, but is generally used for adult males and females. It may be set with reference to a table storing the speed. Thereafter, the present location is acquired at regular time intervals (step S10), and the following processing is repeated.

  Based on the acquired current location information, it is determined that the vehicle has arrived at the destination (step S11). If it is determined that the vehicle has arrived, the walking guide is terminated. If it has not arrived, the current walking speed is acquired (step S12), the current required walking speed is calculated based on the current location and the moving condition obtained by the moving condition setting means (step S13), and the current terminal operation is performed. The situation is acquired (step S14), and the second estimated standard walking speed and the second estimated maximum walking speed are estimated (steps S15 and S16). If the mail is being operated, the time required for browsing or creating the mail is estimated (step S17).

  It progresses to step S20 after step S17, and it is determined whether transmission / reception of mail is repeated. If the mail transmission / reception is repeated, the average of the transmission / reception time interval and the mail browsing creation time is obtained (step S40). It is determined whether the time for browsing and creating the mail up to now is within the estimated time (step S41). If it is not within the time, a walking guide other than e-mail will be given. If it is within the estimated time, the process proceeds to step S42, and an appropriate speed at the time of mail browsing, creation, and normal time is calculated. It is determined whether or not all the speeds can be obtained at the estimated maximum walking speed or less (step S43). If not, it is determined that it is not in time to continue the operation of the mobile phone, and the process proceeds to a case other than mail. If an appropriate requested speed can be determined (ie, if the requested speed is less than the estimated maximum individuality), the current speed is compared with the current speed, and if the requested speed exceeds the current speed, the requested speed and the desired arrival time The remaining time until is notified to the user (step S46).

  If it is determined in step S20 that mail transmission / reception has not been repeated, the process proceeds to step S21 to determine whether the mail is being viewed or created. If the mail is being browsed or created, it is determined whether it is currently within the estimated time for viewing or creating the mail (step S30). If the estimated time of e-mail has passed, the process moves to processing other than e-mail. If it is within the estimated time of email, the request speed at the time of reading or creating the email is calculated (step S31). If the speed at the time of email and the speed at the end of email are not found below the estimated maximum walking speed, the mobile phone If the operation is continued, it will not be in time, and the processing for cases other than mail will proceed. If an appropriate speed (requested speed) can be obtained during mailing, it is compared with the current speed. If the requested speed exceeds the current speed, the user is informed of the requested speed and the remaining time until the desired arrival time.

  If the mail is not being viewed or created, the process proceeds to step S22, where the current walking speed is compared with the required walking speed, and it is determined whether or not the current speed is delayed (whether it is in time) (step S22). If it is in time, do nothing and return to step S10 to acquire the current position and repeat the same. If it is determined that it is delayed, it is compared with the second estimated maximum walking speed and it is determined whether or not it is in time to walk at the maximum speed while operating the mobile phone (step S23). If it is in time to operate the mobile device, the necessary walking speed (rapid rhythm using voice or buzzer) is notified (step S24), and the remaining time until the desired arrival time is displayed (or notified by voice) (Step S25).

  If it is determined in step S23 that the maximum speed while operating the mobile terminal is not in time, the first estimated maximum walking speed is compared with the required maximum speed, and the maximum speed without operating the mobile phone is compared. It is determined whether it is in time (step S26). If it is determined that it is in time, if the user continues to operate at the required walking speed and the mobile terminal, it will not be in time and a rushing rhythm will be notified (step S27). Cancel the operation of the mobile device before the time required to walk at the first estimated maximum walking speed (that is, the remaining time that the terminal operation can continue) and the remaining time that the terminal operation can continue is zero The user is notified that this should be done (step S28).

  If it is determined in step S26 that the maximum walking speed without operating the mobile phone is not in time, the user is informed that the arrival time is not in time and the walking guide is terminated. Through the above processing, it is possible to prevent the user from being out of time by operating the mobile phone by estimating the speed at the time of operating the mobile phone. It is possible to perform a walking guide suitable for creation. That is, it is possible to optimize the balance between mail creation / browsing work and arrival at the destination within the target time.

  FIG. 9 is a flowchart of processing for updating a table (operation influence table) for estimating the operation influence degree of the terminal. As shown in FIG. 9 (a), during normal walking without walking guidance, the first estimated standard walking speed, the first estimated maximum walking speed, and the second estimated maximum speed are estimated first (step P1, P2, P3). Thereafter, the actual walking speed is acquired (step P4), and information on the operation status of the terminal is acquired (step P6). If the terminal is being operated, the first estimated maximum walking speed and the actual maximum walking speed are acquired (step P5), and the portion related to the maximum walking speed in the operation influence degree table is updated (step P7). In Step P7, the first estimated standard walking speed and the actual standard walking speed are further compared, and the portion related to the standard walking speed in the operation influence degree table is updated.

  As shown in FIG. 9B, during the walking guide process, the first estimated maximum walking speed and the second estimated maximum walking speed are estimated (steps P10 and P11), and the user is asked to walk at the maximum speed when operating the terminal. The actual maximum walking speed at the time of transmission is acquired (step P12). The terminal operation status is acquired (step P13), and the portion related to the maximum walking speed in the operation influence degree table is updated based on the first estimated maximum walking speed and the actual maximum walking speed (step P14). From the above processing, it is possible to construct a terminal operation influence degree table customized for the user.

  FIG. 10 is a diagram illustrating a method of updating the operation influence degree table. As shown in FIG. 10A, the operation influence degree table estimates the influence degree at each operation based on the memory of the first estimated standard walking speed or the difference between the first estimated maximum walking speed and the actual walking speed. And hold. In FIG. 10, as an example, the degree of influence at the time of mail creation is estimated based on the storage of a plurality of influence degrees.

  As shown in FIG. 10B, the memory of the influence degree of the standard walking speed is obtained by calculating the influence degree (difference between the first estimated standard walking speed and the actual standard walking speed) at the normal walking time when the walking guide is not performed. Remember. The degree of influence of a predetermined number n is stored and averaged to obtain the degree of influence of the standard walking speed. If the new influence is memorized and the memory exceeds a predetermined number n, the oldest memory is erased. In the initial state, since there is no actual influence degree stored, one general influence degree value is stored as a default. If even one actual memory is entered, the default value is erased.

  As shown in FIG. 10 (b), the maximum walking speed influence degree is stored as a difference between the first estimated maximum speed and the actual maximum speed when the walking guide is performed and when the walking guide is not performed. Remember. If the actual maximum speed is faster than the second estimated maximum walking speed, and the maximum speed when the walking guide means asks the user to walk at the maximum speed is slower than the second estimated maximum walking speed. ”And store a predetermined number o and p respectively. If the new influence is memorized and the memory exceeds a predetermined number n, the oldest memory is erased. When walking, if the actual maximum speed is faster than the second estimated maximum walking speed, and the maximum speed when the walking guide means asks the user to walk at the maximum speed is the second estimated maximum walking The degree of influence of both when the speed is slower than the speed is memorized, and the maximum speed when the walking guide means asks the user to walk at the maximum speed during normal walking without walking guide is the second estimated maximum walking speed The degree of influence is stored only when it is later. The average of both memories is calculated and set as the degree of influence of the maximum walking speed in a predetermined operation situation. In the initial state, since there is no actual influence degree stored, one general influence degree value is stored as a default. If even one actual memory is entered, the default value is erased. With the above processing, it is possible to construct a table of the degree of influence on the walking speed of the mobile terminal operation customized for each user. Further, by setting the default value, it is possible to perform the walking guide even in the initial state where the actual influence degree is not stored.

  FIG. 11 is a diagram illustrating an example of a walking guide during a call. The vertical axis is the walking distance, the horizontal axis is the time, the solid line is the actual walking during the call, the thin broken line is the second estimated maximum speed during the call, the thick broken line is the first estimated maximum speed, and the white circle Y point is the first estimated maximum The point where it is judged that it is not in time for the speed, and the gray circle X point is the point where it is judged that it is not in time for the second estimated maximum speed. When the user leaves the starting point, the first estimated maximum speed is estimated. If the mobile phone is operated by the mobile phone detection means, the second estimated maximum speed in the detected operation state is estimated. In addition, the necessary walking speed at each time point is continuously calculated at regular time intervals. In FIG. 11, since the walking speed is lower than the required walking speed at the time of departure, the required walking speed is notified. The same speed is kept in the call state as it is, and the required maximum maximum speed at the time of A becomes equal to the second estimated maximum speed at the time of the call. Even after passing A, the same speed was maintained, and the required maximum speed exceeded the second estimated maximum speed at the time of the call, so at point X, `` If you keep talking for a long time, it will not be in time for the desired arrival time '' and `` Current If the speed is maintained, the user is informed how long it will be necessary to walk at the first estimated maximum speed. If the same walking speed is maintained after point X and the required walking speed exceeds the first estimated maximum speed at point Y, the user is informed that it has been determined that the desired arrival time is not in time.

  If the mobile terminal is operated for a long time, it is notified that it is not in time for the desired arrival time, so that it is possible to avoid delaying the desired arrival time due to the use of the mobile terminal. On the other hand, before the “notification that the desired arrival time cannot be kept while operating the mobile device for a long time” at the point X, the user knows that the mobile device is notified in time for walking, If you walk at the necessary speed, you can walk while operating the mobile terminal throughout the walk and arrive at your desired arrival time. It will be notified when it is notified that it will not be in time for the desired arrival time if the mobile terminal is operated for a long time, and if it keeps the current speed, it will be necessary to walk at the first estimated maximum speed in the remaining time The user can recognize how long the portable terminal can be operated after this time according to the information on whether or not.

  FIG. 12 is a diagram illustrating an example of a guide when operating the mobile terminal device according to the present invention. FIG. 12 (a) does not particularly calculate the appropriate speed at the time of mail creation and thereafter (no application of the present invention), FIG. 12 (b) shows the case of calculating the appropriate speed at the time of mail creation and thereafter (this book The invention is applicable). The horizontal axis is time and the gray part on the left side of each graph is the time area where mail is created, the vertical axis is the distance traveled, the solid line is the requested walking speed transmitted from the walking guide means to the user, and the thin broken line is mail The second estimated standard walking speed at the time, and the thick broken line is the first estimated standard walking speed at the normal time.

  In the case of the graph of FIG. 12A, since an appropriate speed at the time of e-mail is not calculated, when the user walks according to the requested walking speed, the requested walking speed is constant from departure to desired arrival time. Therefore, during mail creation, the requested speed greatly exceeds the second estimated standard walking speed at the time of creating the mail, and in the situation of mail creation, it is forced to speed up considerably, and the user is instructed the requested walking speed that is very burdensome Will be. On the other hand, after completing the mail creation work, the walking speed information that lacks the balance that the requested walking speed is lower than the first estimated standard speed, the requested speed is not communicated to the user, and the user can afford to walk as usual. Will be instructed.

  In the case of the graph of FIG. 12B, since an appropriate speed at the time of mail is calculated by applying the present invention, the required walking speed during mail creation and after mail creation is approximately equal to the estimated standard speed. It is faster than the rate. The user only needs to hurry a little bit more than usual from departure to arrival, and is not asked to hurry excessively more than usual during composing mail. That is, it can be seen that appropriate walking navigation information is presented in consideration of the situation of mail creation. This makes it easy to create emails even during walking guides, and it is possible to reduce the risk of falls and collisions caused by rushing too much.

  FIG. 13 is a timing chart illustrating an example of a walking rhythm that the terminal notifies the user. As shown in the figure, FIG. 13 (a) shows a rhythm of vibration or sound when transmitting a walking sensation at a relatively low speed, and FIG. 13 (b) shows a rhythm when transmitting a walking interval at a relatively high speed. FIG. 13 (c) shows an example of rhythm transmitted when it is determined that the time is not met. A rhythm representing a walking interval (interval of one step) is transmitted to the user 16 by vibration or sound. Represents the time interval (walking interval) obtained by dividing the current required speed by the current stride obtained by the walking speed acquisition means 28, and walking at the required stride while walking the stride as it is can walk at the required speed and arrive It is possible to arrive at the destination at the desired time. Since (a) vibrates at a relatively long interval or makes a sound, it walks at a relatively slow speed when walking according to the vibration and sound of (a) without changing the stride. In addition, the interval of (b) is short, and it becomes faster to walk according to the vibration and sound of (b) without changing the stride. In this way, it is possible to convey the speed more accurately by telling what walking interval should be used while keeping the stride as it is. By enabling walking at an optimal speed without looking at the screen of the mobile terminal, a more optimal walking guide is possible. When it is estimated that even if it runs at the maximum walking speed, it will not be in time for the desired arrival time, it informs the user 16 of a rhythm that cannot be walked together. (c) Tells the user 16 that he / she cannot walk in step by step with the vibration / sound because the vibration / sound for a long time is combined with the sound for a short time. Is possible.

  FIG. 14 is a diagram illustrating a screen interface that the terminal presents to the user as walking navigation information. As shown in the figure, FIG. 14A is an example of a display screen when the walking guide is not in time for the current speed and a higher speed is transmitted to the user 16. Tamagawa Station is the destination, 7:20 is set as the desired arrival time, and the remaining time and urgent need to be displayed. FIG. 14B is an example of a display screen when it is determined that it is not in time for the desired arrival time (moving conditions cannot be achieved), and displays that it is not in time. The user 16 can know the speed necessary to make it in time and the fact that it is not in time by vibrations and sounds without looking at the display screen, but cannot know the time. Time information such as the remaining time until the desired arrival time can be confirmed by displaying it on the screen.
