Description

  The present invention has a navigation function, and is preferably provided in, for example, a mobile phone, a PHS phone (PHS: Personal Handyphone System), a PDA device (PDA: Personal Digital (Data) Assistants), a car navigation device, a portable navigation device, or the like. The present invention relates to a portable terminal device, and more particularly to a portable terminal device that assists navigation performed by a map image or voice guidance with vibration, light, or electronic sound.

  Today, navigation services based on the current position detected by a mobile phone equipped with a GPS sensor (GPS: Global Positioning System) and current position information transmitted from a base station are received by the mobile phone and are navigated. Services that perform are known. In these navigation services, map information and current position information are displayed on the display unit of the mobile phone, or the navigation service is performed using voice guidance.

  Japanese Patent Laid-Open No. 2000-329575 (Patent Document 1) discloses a navigation system that performs navigation by vibration of a vibration without using screen display or voice guidance.

  In the case of the navigation system disclosed in this Patent Document 1, when the processing control unit 16 acquires the current position of the own vehicle via the GPS module 12, the relationship between the current position of the own vehicle and the guidance route is used for the receiving terminal. It is determined whether or not a guidance instruction is necessary. If it is determined that a guidance instruction is necessary, the processing control unit 16 generates predetermined control data and supplies it to the transmission processing unit 14. When the transmission processing unit 14 generates a control signal from the acquired control data, the transmission processing unit 14 supplies the demodulated control data to the control unit. The control unit determines the validity of the acquired control data, and then vibrates and drives the vibration unit according to the acquired control data.

  That is, in the case of this navigation system, for example, the vibration unit of the vibration unit that means a right turn has a vibration frequency of 2 times, the vibration unit of the vibration unit that means a left turn has a vibration frequency of 4 times, etc. When the number of vibrations is set in advance, the vibration unit is vibrated twice when the distance to the intersection to turn right is within the predetermined distance, and the distance to the intersection to turn left is within the predetermined distance The user is guided along the guide path by vibrating the vibration unit four times. Thereby, navigation can be realized only by vibration of vibration without using screen display or voice guidance.

JP 2000-329575 A (pages 8-9: FIG. 4)

  Here, the case where navigation is necessary often means that the user is walking on an uninformed land. For this reason, it is also preferable to move while confirming the current position and the guidance route by the map information and the current position information displayed on the display unit, and voice guidance. However, being distracted by the map information, current position information, and voice guidance displayed on the display unit is not preferable for a user who is walking on an uninformed land. Therefore, the vibration unit is preferably used as an auxiliary function for guiding the user along the guide route.

  However, since the navigation system disclosed in Patent Document 1 is basically intended to guide the user only by vibration of the vibration unit, when the user is moving accurately along the guidance route When the user reaches the vicinity of the intersection, the vibration unit can be vibrated to guide the user in the correct direction along the guide route. However, the user is accurately moving along the guide route. If not, it is difficult to guide the user in the correct direction along the guide path.

  For example, when the user moves off the guidance route and moves in the direction opposite to the destination, the navigation system disclosed in Patent Document 1 makes it difficult for the user to recognize such a problem. . For this reason, in the navigation system disclosed in Patent Document 1, in such a case, the user may gradually move away from the destination, and there may be a disadvantage that the user cannot reach the destination.

  The present invention uses a vibration unit or the like to reach the destination from the current position to the destination (the distance from the current position to the destination) or the current time. The purpose is to provide a mobile terminal device that can assist the navigation by allowing the user to recognize the remaining time until the desired time (how much time is available from the current time to the desired arrival time), etc. .

  The present invention has a navigation function for displaying current position information and a guidance route to a desired destination on a map image around the current position, and performing navigation by the map image or the map image and voice guidance.

Thereby, the drive state of the notification means can be changed according to the difference in the distance and the time difference between the desired arrival time and the current time, and the distance to the destination and the destination in the pattern in which the notification means is driven. The remaining time until the desired arrival time can be notified to the user.

In addition to the means described above, the present invention

It is possible to notify whether the pace is an early pace, a slow pace, or just a good pace with respect to the time at which arrival at the destination is desired.

  In the present invention, the control means controls the drive of the notification means with the drive pattern changed according to the distance between the current position detected by the current position detection means and the destination, thereby changing the drive state of the notification means. The distance can be changed according to the difference in the distance, and the distance to the destination can be notified to the user by the pattern in which the notification means is driven.

  Further, according to the present invention, the control unit controls the driving of the notification unit with the driving pattern changed according to the distance between the current position detected by the current position detection unit and the destination, and the desired arrival time and the current time Driving control of the notification means with the driving pattern changed according to the time difference between, the driving state of the notification means can be changed according to the difference in the distance and the time difference between the desired arrival time and the current time, With the pattern in which the notification means is driven, the user can be notified of the distance to the destination and the remaining time until the desired arrival time.

Etc. are stored.

[Registration of various information]
When using such a navigation function of the mobile phone, the user registers various information prior to the execution of the navigation. The flowchart shown in FIG. 2 illustrates the registration of various information performed by the user as a flowchart.

  In the flowchart of FIG. 2, the user first registers a destination (step S1). Specifically, when the navigation function is used, the user operates the operation unit 6 to select execution of the navigation application program from the application menu displayed on the display unit 5. When this selection is made, the control unit 13 activates the navigation program stored in the memory 12 and controls the GPS unit 9 to detect the current position of the mobile phone based on the navigation program. When the GPS unit 9 (and the GPS antenna 8) detects the current position of the mobile phone, the control unit 13 uses the communication program stored in the memory 12 to store the position information indicating the current position. To the base station. The base station transfers location information indicating the current location to a navigation server device that manages the navigation service.

  When the navigation server device receives the position information indicating the current position, the navigation server device forms navigation image information in which an icon indicating the current position of the mobile phone is added to the map image around the current position, and this is transmitted via the base station. To the user's mobile phone. Upon receiving this navigation image information, the control unit 13 of the user's mobile phone controls display on the display unit 5 together with the navigation image information, a message prompting the user to set a destination such as “Please set destination”. . Note that the message for prompting the destination setting may be pronounced through the speaker unit 3 as voice.

  Next, the user operates a cross key, a rotation operation key, or the like provided on the operation unit 6 while viewing the map information displayed on the display unit 5. When the cross key, the rotation operation key, or the like is operated, the control unit 13 controls to move and display the icon on the map image displayed on the display unit 5 according to the operation. The user operates the cross key or the rotation operation key to move the icon displayed on the display unit 5 to a desired destination on the map image, and operates the determination key of the operation unit 6. . When the control unit 13 detects the operation of the determination key, the control unit 13 transmits position information (= destination position information) indicating the position of the icon that has been moved and the current position information of the mobile phone to the navigation server device. At the same time, the location information (destination information) of the destination is stored and controlled in the memory 12.

  The navigation server device, based on the current position information of the mobile phone and the position information of the destination, map image information to which information indicating a guidance route from the current position to the destination is added, and the current position Information indicating the distance to the destination is formed and transmitted to the user's mobile phone. The control unit 13 of the mobile phone controls the display unit 5 to display the map image information and information indicating the distance from the current position to the destination. As a result, the display unit 5 includes an icon indicating the current position of the user and a map image to which information indicating a guidance route from the current position to the destination is added, and between the current position and the destination. Characters indicating the distance will be displayed.

  Next, the user registers a reference distance and a reference pattern as steps S2 and S3 in the flowchart shown in FIG.

  That is, as described above, in the case of this mobile phone, the distance between the destination and the current position is notified to the user by light, vibration or electronic sound. When performing a navigation assist operation that informs the user of the distance between the destination and the current position, whether the user is moving closer to the destination or whether the user is moving away from the destination. , It is necessary to inform the user. For this purpose, it is necessary to determine in advance a reference distance and a reference operation pattern for performing this auxiliary operation. For this reason, in the case of the mobile phone, this “reference distance (reference distance)” is registered in step S2, and “operation pattern (reference pattern)” at the reference distance is registered in step S3. It has become.

  Specifically, when the registration of the destination in step S1 is completed, the control unit 13 of the mobile phone displays a message on the display unit 5 prompting registration of the reference distance such as “Register the reference distance”. Control. As described above, since the distance from the current position to the destination is displayed on the display unit 5 when the destination is registered, the user can view the distance from the current position to the destination. Can recognize the distance. After the user recognizes the distance from the current position to the destination, the user inputs, for example, a distance between the current position and the destination by operating the numeric keypad of the operation unit 6 and the like. Operate the Enter key.

  For example, when the distance from the current position to the destination is 1 km, the user inputs a desired distance such as “500 m” or “300 m” as the reference distance. When the reference distance is input and the operation of the determination key is detected, the control unit 13 of the mobile phone stores and controls the distance input by the user in the memory 12 as the reference distance.

Next, when the registration of the reference distance is completed, the control unit 13 sets the target of the auxiliary operation and the reference pattern of the reference pattern, such as “Please select the target to perform the auxiliary operation and the reference pattern”, for example. A message prompting selection is displayed on the display unit 5. The user operates the enter key in response to this message to display an intention to accept the selection of the target to perform the auxiliary operation and the reference pattern. The control unit 13 operates the enter key. Is detected, for example, 1. Vibration unit (vibration)
2. LED (light)
3. Display control of a screen for selecting a target for performing an auxiliary operation such as electronic sound is performed together with a cursor.

  The user operates the operation unit 6 to move the cursor to a target display position where a desired auxiliary operation is performed, and operates the enter key. When the control unit 13 detects the operation of the determination key, the control unit 13 recognizes the target for performing the auxiliary operation at which the cursor is located when the determination key is operated as the target for performing the auxiliary operation selected by the user. To do.

  For example, when the user moves the cursor to the display position of “1. Vibration unit (vibration)” and the enter key is operated, the control unit 13 moves the “1. Vibration unit (vibration)” to the user. It recognizes as an object which performs auxiliary operation selected by. Similarly, when the user moves the cursor to the display position of “3. electronic sound” and the determination key is operated, the control unit 13 uses the “3. electronic sound” as the auxiliary selected by the user. Recognized as an object to be moved.

  Next, when the target for performing the auxiliary operation is selected by the user in this way, the control unit 13 displays a pattern table in which the operation pattern corresponding to the target for performing the auxiliary operation selected by the user is stored. The data is read from the memory 12 and displayed on the display unit 5.

  That is, the memory 12 stores a “vibration pattern table”, a “light emission pattern table”, and a “sound generation pattern table”. When the user selects “1. Vibration unit (vibration)” as a target to perform the auxiliary operation, the control unit 13 reads out the “vibration pattern table” from the memory 12 and controls display on the display unit 5. . Similarly, when “2. LED (light)” is selected by the user as a target for performing the auxiliary operation, the control unit 13 reads the “light emission pattern table” from the memory 12 and displays it on the display unit 5. Control.

  “Vibration pattern table” includes, for example, “vibration intensity → level 1 to level 5 (5 levels)”, “vibration interval → 1 second interval, 5 second interval, 10 second interval, 30 second interval, 1 minute interval, 3 minute intervals, 5 minute intervals ... "," vibration time → 1 second, 3 seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds ... ", etc. The table stores the interval and vibration time. When the user selects “1. Vibration unit (vibration)” as an object to perform the auxiliary operation, the user can obtain the desired vibration intensity, vibration interval and vibration time at the reference distance from the “vibration pattern table”. Will be selected.

  “Light emission pattern table” includes, for example, “light emission intensity → level 1 to level 5 (5 levels)”, “light emission interval → 1 second interval, 5 second interval, 10 second interval, 30 second interval, 1 minute interval, 3 minute intervals, 5 minute intervals, etc. "," Luminescence time → 1 second, 3 seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds ... "etc. The table stores the interval and the light emission time. When the user selects “2. LED (light)” as a target to perform the auxiliary operation, the user selects a desired light emission intensity, light emission interval, and light emission time at the reference distance from the “light emission pattern table”. Will be.

  “Sound generation pattern table” includes, for example, “sound volume → level 1 to level 5 (5 levels)”, “sound generation interval → 1 second interval, 5 second interval, 10 second interval, 30 second interval, 1 minute interval, "3 minute intervals, 5 minute intervals ...", "Sound generation time → 1 second, 3 seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds ...", etc. It is a table in which intervals and pronunciation times are stored. When the user selects “3. electronic sound” as a target to perform the auxiliary operation, the user selects a desired sound volume, sounding interval and sounding time at the reference distance from the “sounding pattern table”. It becomes.

  When a desired pattern is selected from any one of the pattern tables, the control unit 13 recognizes the selected operation pattern as an operation pattern at the reference distance. Then, the “target to perform auxiliary operation” and “the target operation pattern to perform auxiliary operation” selected by the user are stored and controlled in the memory 12 as “reference pattern information”. Accordingly, the memory 12 stores, for example, “subject to perform auxiliary operation: vibration unit”, “operation pattern: vibration for 3 seconds at 10-second intervals”, or “subject to perform auxiliary operation: LED”, “operation pattern: “Reference pattern information” is stored such as “lights for 5 seconds at 1 minute intervals”.

[Normal navigation operation]
Next, the “destination information”, “reference distance information”, and “reference pattern information” are stored in the memory 12 in this way, and when the start of navigation is designated by the user, the navigation operation in the mobile phone is started. The When the navigation operation is started, the control unit 13 of the mobile phone continuously or intermittently displays an icon indicating the current position displayed on the map image of the display unit 5 with the GPS antenna 8 and the GPS unit 9. The mobile display is controlled according to the current position of the mobile phone detected at the time. If voice navigation is also used, for example, a navigation message such as “next intersection is in the right direction” is sounded via the speaker unit 3. The user moves while confirming the current position and the guidance route by the map image displayed on the display unit 5 and the icon (and voice) indicating the current position. Thereby, a user's navigation by a map image (and sound) will be performed.

[Navigation assistance]
On the other hand, in this mobile phone, while navigation of the user by such a map image (and sound) is being performed, the above-mentioned “vibration unit”, “LED”, etc. selected by the user are used to assist this navigation. Operation is performed. The flowchart of FIG. 3 shows the flow of this navigation assist operation.

  The flowchart of FIG. 3 starts when the start of navigation is designated by the user. When the start of navigation is designated by the user, the control unit 13 of the mobile phone acquires the current position of the mobile phone detected by the GPS antenna 8 and the GPS unit 9 in step S11, and the process proceeds to step S12. Proceed.

  In step S12, the control unit 13 calculates a distance difference between the current position of the mobile phone acquired in step S11 and the destination stored as destination information in the memory 12, and the process proceeds to step S13. Proceed.

  In step S13, based on the calculated distance difference and the reference distance and reference pattern stored in the memory 12 as the reference distance information and reference pattern information, the driving of the “target to be assisted” selected by the user is performed. Determine the pattern. Then, in step S14, the control unit 13 supplies a control signal corresponding to the determined drive pattern to the “target to perform the auxiliary operation” selected by the user, and based on the determined drive pattern. The above “subject to perform auxiliary operation” is driven.

(Vibration unit)
For example, “vibration unit” is selected as “subject to perform auxiliary operation”, and the reference pattern of the vibration unit is “vibration intensity → level 3 (level 3 out of 5 levels)”, “vibration unit” When “interval → 1 second interval” and “vibration time → 1 second” are registered, “500 m” is registered as “reference distance”, and the “distance difference” is calculated as “700 m”, the control unit 13 Determines the drive pattern as follows.

  In this case, the current position of the user is 700 m away from the destination, and is 200 m farther than 500 m registered as the “reference distance”. As the drive pattern, since the vibration unit is registered to vibrate for 1 second at 1 second intervals at a point 500 m from the destination, the control unit 13 sets the vibration intensity to level 4, for example, and sets the vibration interval. The vibration intensity is reduced and the vibration interval is widened as much as 200 m away from the above “reference distance”, such as every 1.5 seconds and vibration time of 1.5 seconds. The vibration unit 10 is vibrated and driven with this drive pattern.

  In the case of this example, at the reference distance, a drive pattern for vibrating the vibration unit 10 for 1 second every second with the vibration intensity of level 3 is registered, whereas the vibration unit 10 The vibration unit 10 vibrates for 1.5 seconds every 1.5 seconds, so the vibration unit 10 is vibrated for a long time with a weaker vibration and longer intervals than the reference drive pattern. Therefore, it is possible to make the user recognize that the current position is farther than the reference distance.

  Similarly, when the “distance difference” is calculated as “200 m”, the current position of the user is 200 m away from the destination, and is closer to the destination 300 m than 500 m registered as the “reference distance”. ing. In this case, for example, the control unit 13 sets the vibration intensity to level 2, the vibration interval is set to every 0.5 seconds, and the vibration time is set to 0.5 seconds. On the other hand, the vibration intensity is increased as much as 300 m from the destination, the drive interval is shortened and the vibration time is shortened, and the vibration unit 10 is driven to vibrate with this drive pattern.

  In the case of this example, at the reference distance, a drive pattern for vibrating the vibration unit 10 for 1 second every second with the vibration intensity of level 3 is registered, whereas the vibration unit 10 The vibration unit 10 is vibrated for 0.5 seconds every 0.5 seconds, so that the vibration unit 10 is vibrated and driven at a short time and a stronger vibration than the reference drive pattern. Therefore, it is possible to make the user recognize that the current position is closer to the reference distance.

(In the case of LED)
Similarly, for example, “LED” is selected as “subject to perform auxiliary operation”, and the reference pattern of this LED is “light emission intensity → level 3 (level 3 out of 5 levels)”, “light emission When “interval → 1 second interval” and “light emission time → 1 second” are registered, “500 m” is registered as “reference distance”, and the “distance difference” is calculated as “800 m”, the control unit 13 Determines the drive pattern as follows.

  In this case, the current position of the user is 800 m away from the destination, and is 300 m far from 500 m registered as the “reference distance”. As the driving pattern, since the light emitting unit is registered to drive light emission at a point of 500 m from the destination for 1 second at intervals of 1 second, the control unit 13 sets the light emission intensity to level 4, for example, As the interval is set to 1.7 seconds and the vibration time is set to 1.7 seconds, the intensity of light emission is decreased and the light emission interval is reduced by 300 m from the “reference distance” of 500 m. The drive pattern is made wider and the light emission time is longer, and the light emitting section 7 is driven to emit light with this drive pattern.

  In the case of this example, at the reference distance, a driving pattern is registered in which the light emitting unit 7 emits light for 1 second every second at the intensity of light emission of level 3, whereas the light emitting unit 7 Since the light emission intensity is 4 for 1.7 seconds every 1.7 seconds, the light emitting section 7 is driven to emit light for a long time at a longer interval with a weaker light emission than the reference drive pattern. Therefore, it is possible to make the user recognize that the current position is farther than the reference distance.

  Similarly, when the “distance difference” is calculated as “100 m”, the current position of the user is 100 m away from the destination, and is closer to the destination 400 m than 500 m registered as the “reference distance”. ing. In this case, the control unit 13 is the above “reference distance” such that the intensity of light emission is set to level 1, the light emission interval is set to every 0.2 seconds, and the light emission time is set to 0.2 seconds. The light emission intensity is increased, the light emission interval is shortened, and the light emission time is shortened as much as 400 m from the destination with respect to 500 m, and the light emitting unit 7 is driven to emit light with this drive pattern.

  In the case of this example, at the reference distance, a driving pattern is registered that causes the light emitting unit 7 to vibrate for 1 second every second with the intensity of vibration of level 3, whereas the light emitting unit 7 Since the light is emitted for 0.2 seconds every 0.2 seconds with the intensity of light emission of 1, the light emitting unit 7 is driven to emit light for a short time at a shorter interval with stronger light than the reference driving pattern. Therefore, it is possible to make the user recognize that the current position is closer to the reference distance.

(In the case of electronic sound)
Similarly, for example, “electronic sound” is selected as “subject to perform auxiliary operation”, and the reference pattern of this electronic sound is “sound volume → level 3 (level 3 out of 5 levels)”, “ When “sound generation interval → 1 second interval” and “sound generation time → 1 second” are registered, “500 m” is registered as “reference distance”, and “distance difference” is calculated as “600 m”, the control unit 13 determines the drive pattern as follows.

  In this case, the current position of the user is 600 m away from the destination, and is 100 m far from 500 m registered as the “reference distance”. As the drive pattern, since the electronic sound is registered to sound at level 3 for 1 second at 1 second intervals at a point 500 m from the destination, the control unit 13 sets the sound level to, for example, level. 4 and the sounding interval is 1.2 seconds, the sounding time is 1.2 seconds, etc. The driving pattern is set to be small, the sounding interval is widened, and the sounding time is lengthened, and the electronic sound such as a beep sound corresponding to the driving pattern is controlled to be generated via the speaker unit 3.

  In the case of this example, at the reference distance, a driving pattern in which an electronic sound is generated for 1 second every 1 second at a level 3 level is registered, whereas at a level 4 level, 1. Since an electronic sound is generated every 2 seconds for 1.2 seconds, the electronic sound is controlled to be generated for a long time at a longer interval with a smaller sound than the reference driving pattern. Thus, it can be recognized that the current position is farther than the reference distance.

  Similarly, when the “distance difference” is calculated as “400 m”, the current position of the user is 400 m away from the destination, and is closer to the destination 100 m than 500 m registered as the “reference distance”. ing. In this case, for example, the control unit 13 sets the sound volume to level 2, sets the sound generation interval to every 0.7 seconds, sets the sound generation time to 0.7 seconds, and the like, and the “reference distance” is 500 m. On the other hand, the electronic sound of the drive pattern in which the sound volume is increased, the sound generation interval is shortened, and the sound generation time is shortened as much as 100 m from the destination is controlled through the speaker unit 3.

  In the case of this example, at the reference distance, a driving pattern for sounding an electronic sound every second at a level of 3 is registered, whereas at a level of 2 it is 0.7 Since an electronic sound is generated for 0.7 seconds every second, the electronic sound is controlled to generate a sound that is louder than the reference drive pattern and at short intervals for a short time. On the other hand, it can be recognized that the current position is closer to the reference distance.

  Note that, in this navigation assist operation, in step S15 of the flowchart of FIG. 3, the control unit 13 detects the navigation end operation performed by the user or detects that the user has reached the destination. It is repeatedly executed until

[Effect of the first embodiment]
As is apparent from the above description, the cellular phone according to the first embodiment is selected by the user as “subject to perform auxiliary operation (vibration unit 10, light emitting unit 7, or speaker unit 3 (electronic sound)). Can be driven with a drive pattern corresponding to the distance between the current position of the user and the destination. Thereby, the distance to the destination can be notified to the user by the vibration of the vibration unit 10 or the light of the light emitting unit 7, and it is pronounced via the map information displayed on the display unit 5 or the speaker unit 3. It is possible to assist navigation performed based on voice guidance.

[Second Embodiment]
Hereinafter, a mobile phone according to a second embodiment of the present invention will be described. The cellular phone according to the first embodiment described above controls driving of the vibration unit 10 or the light emitting unit 7 according to the difference in distance between the current position and the destination, or controls the sound generation of the electronic sound from the speaker unit 3. However, the mobile phone according to the second embodiment responds to “the distance difference between the current position and the destination, and the time difference between the time when the user wishes to arrive at the destination and the current time”. The navigation is assisted by controlling the target (vibration unit 10, light emitting unit 7, or speaker unit 3) on which the auxiliary operation is performed.

  In the first embodiment and the second embodiment, based on the “distance to the destination” and the “time difference between the time when the user wants to arrive at the destination and the current time”, The only difference is that the target for performing the auxiliary operation is controlled. For this reason, in the following description, only this difference will be described, and redundant description will be omitted.

[Registration of desired arrival time]
In the case of the mobile phone according to the second embodiment, the destination registration, reference distance registration and reference pattern registration described with reference to FIG. ‘Desired time’, ‘reference time difference’ that is a time difference serving as a reference between the time at which the user wishes to arrive at the destination and the current time, and an operation pattern that is a reference for a target for performing the auxiliary operation at the reference time difference. Register "reference pattern".

  The flowchart of FIG. 4 illustrates the registration of the “desired destination arrival time”, “reference time difference”, and “reference pattern” performed by the user as a flowchart. In this example, registration of “desired destination arrival time”, “reference time difference”, and “reference pattern” is performed using the “destination”, “reference distance”, and “reference pattern” described with reference to the flowchart of FIG. "Is registered (or may be before registration).

  In the flowchart of FIG. 4, first, in step S <b> 21, the user registers a “destination arrival scheduled time” that is a time at which arrival at the destination is desired. Specifically, when the registration of the “destination”, “reference distance”, and “reference pattern” described with reference to the flowchart of FIG. The display unit 5 is controlled to display a message that prompts the user to set the desired arrival time for the destination. Note that the message prompting the user to set the desired arrival time for the destination may be pronounced through the speaker unit 3 as voice.

  Next, the user operates the numeric key provided on the operation unit 6 to input the desired arrival time at the destination and operate the enter key. When detecting the determination key n operation, the control unit 13 controls the memory 12 shown in FIG. 1 to store and control the desired arrival time (desired arrival time information) input by the user.

  Next, the user registers a reference time and a reference pattern as step S22 and step S23 in the flowchart shown in FIG.

  That is, in the case of the mobile phone according to the second embodiment, the “distance between the destination and the current position” and the “time difference between the time when the user wishes to arrive at the destination and the current time (= remaining time)” Assisting navigation by informing the user by light, vibration or electronic sound. When such a navigation assist operation is performed, it is necessary to previously determine an operation pattern for the remaining time as a reference, together with registration of the “reference distance” and the “reference pattern” described with reference to the flowchart of FIG.

  For this reason, in the case of the mobile phone of the second embodiment, this “remaining reference time (reference time difference)” is registered in step S22, and this reference remaining time is reached in step S23. The “operation pattern (reference pattern)” is registered.

  Specifically, when the registration of the desired arrival time at the destination in step S21 is completed, the control unit 13 of the mobile phone prompts registration of a reference time difference such as “Please register the remaining time as a reference”. Message display control is performed on the display unit 5. The user recognizes the input desired arrival time and the current time and inputs the remaining time as a reference such as 30 minutes or 10 minutes by operating the numeric keypad of the operation unit 6. Operate the Enter key. When the reference time difference is input and the operation of the determination key is detected, the control unit 13 controls the memory 12 to store information on the desired remaining time input by the user as reference time difference information.

  Next, when the registration of the reference time difference is completed, the control unit 13 determines the target of the auxiliary operation and the reference pattern, such as “Please select the target and the reference pattern for the auxiliary operation”. A message prompting selection is displayed on the display unit 5.

  That is, in the case of the mobile phone according to this embodiment, the “target to perform auxiliary operation and its reference pattern” corresponding to the “distance” described with reference to the flowchart of FIG. 2 is set, and the flowchart of FIG. Based on the “remaining time”, the “subject to perform auxiliary operation and its reference pattern” are set.

  The “subject to perform auxiliary operation” corresponding to this “remaining time” is selected from the vibration unit, light emitting unit, or electronic sound, and the “reference pattern” is also stored in the memory 12. The selection is made based on each pattern table.

  Further, for example, when “target to perform auxiliary operation” for “distance” is set to “vibration unit” and “reference pattern” is set to “vibration at 10-second intervals for 3 seconds”, this “remaining time” “Auxiliary action target” is set as “LED”, “Reference pattern” is set as “Lit for 5 seconds at 1 minute intervals”, etc. The “target and reference pattern to be operated” and the “target and reference pattern to be used for auxiliary operation” set for “remaining time” can be set differently. “Subject to perform auxiliary operation” is set to “Vibration unit”, “Reference pattern” is set to “Vibration at 10-second intervals for 3 seconds”, and “Subject to perform auxiliary operation” for “Remaining time” is It is also possible to set the “target and reference pattern to perform auxiliary operation” for the distance and the remaining time to be the same by setting “blation unit” and “reference pattern” to “vibration at 10-second intervals for 3 seconds”. .

  The control unit 13 stores and controls, in the memory 12, “target pattern and reference pattern to perform auxiliary operation” corresponding to the remaining time selected by the user as “reference pattern information”.

[Navigation assistance]
Next, also in the mobile phone according to the second embodiment, the “vibration unit”, “LED”, etc. selected by the user while the navigation of the user by the above-described map image (and sound) is performed. Depending on the target to perform the auxiliary operation, an auxiliary operation of navigation corresponding to “distance” and “remaining time” is executed. The flowchart of FIG. 5 shows the flow of the navigation assist operation corresponding to the “remaining time”.

  Note that the flowchart of FIG. 5 shows only the navigation assisting operation corresponding to “remaining time” in order to facilitate understanding of the embodiment, and the navigation assisting operation corresponding to “distance”. Is not shown. However, it is understood that the navigation assistance operation corresponding to the “remaining time” shown in the flowchart of FIG. 5 is executed in parallel with the navigation assistance operation corresponding to the “distance” shown in the flowchart of FIG. I want.

  The flowchart of FIG. 5 starts when the start of navigation is designated by the user. When the start of navigation is designated by the user, the control unit 13 of the mobile phone acquires the current time counted by the timer 11 shown in FIG. 1 in step S31, and advances the process to step S32.

  In step S32, the control unit 13 calculates a time difference (current time difference) between the current time acquired in step S31 and the desired arrival time stored as destination arrival time information in the memory 12, and the process is performed in step S33. Proceed to

  In step S33, based on the calculated current time difference and the reference time difference and the reference pattern stored in the memory 12 as the reference time difference information and the reference pattern information, the driving of the “target to perform the auxiliary operation” selected by the user is performed. Determine the pattern. Then, in step S34, the control unit 13 supplies a control signal corresponding to the determined drive pattern to the “target for performing the auxiliary operation” selected by the user, and based on the determined drive pattern. The above “subject to perform auxiliary operation” is driven.

(Vibration unit)
For example, “vibration unit” is selected as “subject to perform auxiliary operation”, and the reference pattern of the vibration unit is “vibration intensity → level 3 (level 3 out of 5 levels)”, “vibration unit” When “interval → 1 second interval” and “vibration time → 1 second” are registered, “30 minutes” is registered as “reference time difference”, and the above “current time difference” is calculated as “40 minutes”, control is performed. The unit 13 determines the drive pattern as follows.

  In this case, the current time difference is 40 minutes as the remaining time until the time when the user desires to arrive at the destination, and remains 10 minutes longer than 30 minutes registered as the “reference time difference”. As a drive pattern, since the vibration unit is registered to vibrate at level 3 for 1 second at an interval of 1 second at a time point 30 minutes before the desired arrival time, the control unit 13 sets the level of vibration, for example. 4, the vibration interval is every 1.5 seconds, the vibration time is 1.5 seconds, etc. The vibration unit 10 is driven to vibrate with this drive pattern, in which the strength of is reduced, the vibration interval is increased, and the vibration time is increased.

  In the case of this example, in the reference time difference, a drive pattern for vibrating the vibration unit 10 for 1 second every second with the vibration intensity of the level 3 is registered, whereas the vibration unit 10 The vibration unit 10 is vibrated for 1.5 seconds every 1.5 seconds, and the vibration unit 10 is vibrated for a long time with a weaker vibration and longer intervals than the reference drive pattern. Therefore, it is possible to make the user recognize that the time is still more than 30 minutes before the time at which the user wishes to arrive at the destination.

  Similarly, when the “current time difference” is calculated as “20 minutes”, the remaining time until the time when the user wants to arrive at the destination is 20 minutes, and the 30 minutes registered as the “reference time difference” 10 minutes shorter than In this case, the control unit 13 has the above “reference time difference” such as setting the vibration intensity to level 2, the vibration interval to every 0.5 seconds, and the vibration time to 0.5 seconds. The vibration pattern is increased by 10 minutes with respect to 30 minutes, the vibration intensity is increased, the vibration interval is shortened, and the vibration time is shortened. The vibration unit 10 is driven to vibrate with this drive pattern.

  In the case of this example, in the reference time difference, a drive pattern for vibrating the vibration unit 10 for 1 second every second with the vibration intensity of the level 3 is registered, whereas the vibration unit 10 The vibration unit 10 is vibrated for 0.5 seconds every 0.5 seconds, and the vibration unit 10 is vibrated for a short time at short intervals with stronger vibrations than the reference drive pattern. Therefore, it is possible to make the user recognize that 30 minutes before the time at which the user wishes to arrive at the destination has passed and there is no room for the remaining time.

(In the case of LED)
Similarly, for example, “LED” is selected as “subject to perform auxiliary operation”, and the reference pattern of this LED is “light emission intensity → level 3 (level 3 out of 5 levels)”, “light emission When “interval → 1 second interval” and “light emission time → 1 second” are registered, “20 minutes” is registered as “reference time difference”, and the above “current time difference” is calculated as “50 minutes”, control is performed. The unit 13 determines the drive pattern as follows.

  In this case, the current time difference is 50 minutes as the remaining time until the time when the user wants to arrive at the destination, and remains 30 minutes longer than the 20 minutes registered as the “reference time difference”. As the drive pattern, since the light emitting unit 7 is registered to control light emission at level 3 for 1 second at an interval of 1 second at a time point 20 minutes before the desired arrival time, the control unit 13 may, for example, The time is 30 minutes longer than the “reference time difference” of 20 minutes, such as setting the intensity to level 5, the light emission interval every 2.0 seconds, and the light emission time of 2.0 seconds. Accordingly, the intensity of the emitted light is reduced, the light emission interval is lengthened, and the light emission time is lengthened to form a drive pattern.

  In the case of this example, with respect to the reference time difference, a driving pattern for causing the light emitting unit 7 to emit light at a level 3 emission intensity for 1 second every second is registered, whereas the light emitting unit 7 has a level 5 emission level. With the light emission intensity, the light emission is driven for 2.0 seconds every 2.0 seconds, and the light emitting unit 7 is driven to emit light for a long time with a weaker light and at longer intervals than the reference drive pattern. Therefore, it is possible to make the user recognize that there is still a considerable margin in time compared to 20 minutes before the time when the user wishes to arrive at the destination.

  Similarly, when the “current time difference” is calculated as “5 minutes”, it indicates that there is only 5 minutes remaining from the time at which the user wishes to arrive at the destination, and is registered as the “reference time difference”. It is 15 minutes shorter than 20 minutes. In this case, for example, the control unit 13 sets the light emission intensity to level 1, sets the light emission interval to every 0.5 seconds, sets the light emission time to 0.5 seconds, etc. On the other hand, the light intensity is increased by 15 minutes, the light emission interval is shortened, the light emission time is shortened, and the light emission section 7 is driven to emit light with this drive pattern.

  In the case of this example, in the reference time difference, a drive pattern is registered in which the light emitting unit 7 emits light for 1 second every second at the light emission intensity of level 3, whereas the light emitting unit 7 is of level 1 With the light emission intensity, the light emission is driven for 0.5 seconds every 0.5 seconds, and the light emitting unit 7 is driven to emit light with a stronger light than the reference drive pattern at short intervals for a short time. Therefore, it is possible to make the user recognize that 30 minutes before the time at which he or she wants to arrive at the destination has passed and there is no room for the remaining time.

(In the case of electronic sound)
Similarly, for example, “electronic sound” is selected as “subject to perform auxiliary operation”, and the reference pattern of this electronic sound is “sound volume → level 3 (level 3 out of 5 levels)”, “ When “sounding interval → 1 second interval” and “sounding time → 1 second” are registered, “30 minutes” is registered as “reference time difference”, and the above “current time difference” is calculated as “60 minutes” The control unit 13 determines the drive pattern as follows.

  In this case, the current time difference is 60 minutes as the remaining time until the user wants to arrive at the destination, and remains 30 minutes longer than the 30 minutes registered as the “reference time difference”. As the drive pattern, since the electronic sound is controlled to be sounded for one second at an interval of one second at a time point 30 minutes before the desired arrival time, the control unit 13 performs, for example, the volume of the sound of the electronic sound to be generated. For example, the time is 30 minutes longer than the “reference time difference” of 30 minutes, such as setting the level to 5, leveling the sounding interval every 2.0 seconds, and sounding time 2.0 seconds. A drive pattern in which the level of the electronic sound to be generated is reduced, the sound generation interval is extended, and the sound generation time is extended is set, and a predetermined electronic sound is controlled to be generated via the speaker unit 3 with this drive pattern.

  In the case of this example, with respect to the reference time difference, a driving pattern for generating an electronic sound of level 3 for 1 second every second is registered, whereas at level 5 it is 2.0. The electronic sound is controlled to be generated for 2.0 seconds every second, and the electronic sound is controlled to be generated with a smaller sound and at longer intervals than the reference drive pattern. On the other hand, it can be recognized that there is still a considerable margin in time compared to 30 minutes before the time of arrival at the destination.

  Similarly, when the “current time difference” is calculated as “1 minute”, it indicates that there is only one minute remaining from the time at which the user wants to arrive at the destination, and is registered as the “reference time difference”. It is 29 minutes shorter than 30 minutes. In this case, the control unit 13 sets the “reference time difference” to 30, such as setting the level 1 of the sound to be generated, setting the sound generation interval to every 0.1 second, and setting the sound generation time to 0.1 second. The electronic sound to be generated is increased by 29 minutes relative to the minute, the sound generation interval is shortened and the sound generation time is shortened, and sound generation control of the electronic sound is performed with this drive pattern.

  In this example, with respect to the reference time difference, a drive pattern for sounding an electronic sound for 1 second every second with a sound intensity of level 3 is registered, whereas a sound intensity of 0. The electronic sound is controlled to sound every second for 0.1 second, and the electronic sound is controlled to sound louder than the reference drive pattern at short intervals for a short time. On the other hand, it can be recognized that 30 minutes before the time at which the user wishes to arrive at the destination has passed, and that the remaining time has no room.

  Such a navigation assist operation is performed until the control unit 13 detects a navigation end operation performed by the user or detects that the user has reached the destination in step S35 of the flowchart of FIG. It is repeatedly executed for a while.

[Example of complex control of distance and time difference]
Next, “control performed based on the difference between the current position of the user and the destination (see FIG. 3)” and “control performed based on the time difference between the current time and the desired arrival time at the destination (FIG. 5). An example in the case of performing “see” in combination is described.

  For example, the “subject to perform auxiliary operation” for driving control with the “distance difference” is the vibration unit 10, and the “subject to perform auxiliary operation” for driving control with the “time difference” is the light emitting unit 7. In the case (= if the target to perform the auxiliary operation is different), the control unit 13 vibrates the vibration unit 10 according to the difference in the distance between the current position and the destination, and the desired time of arrival at the current time and the destination. The light emitting unit 7 is driven to emit light in accordance with the time difference between. Thereby, the user can recognize the distance to the destination by the vibration of the vibration unit 10, and can recognize the remaining time with respect to the desired arrival time by the light of the light emitting unit 7.

  On the other hand, for example, the “subject to perform the auxiliary operation” for driving control by the “distance difference” is the vibration unit 10, and the “subject to perform the auxiliary operation” for driving control by the “time difference” is also the vibration. If it is the unit 10 (= when the target to perform the auxiliary operation is the same), the control unit 13 vibrates the vibration unit 10 with a drive pattern corresponding to the difference in the distance between the current position and the destination, The vibration unit 10 is vibrated and driven with a drive pattern corresponding to the time difference between the time and the desired arrival time at the destination. In this case, by performing initial registration (see the flowcharts in FIGS. 2 and 4) so that the drive pattern corresponding to the “distance difference” and the drive pattern corresponding to the “time difference” are different. Even when the “subject to perform the auxiliary operation” is the same, the user can recognize the “distance” and the “time” separately.

[Effects of Second Embodiment]
As is clear from the above description, the mobile phone according to the second embodiment is the “object to be subjected to the auxiliary operation (vibration unit 10, light emitting unit 7 or speaker unit 3 (electronic sound)) selected by the user. Can be driven with a drive pattern corresponding to “the distance between the current position of the user and the destination” and “the time difference between the current time and the desired arrival time at the destination”. Thereby, the user can be notified of the distance to the destination and the remaining time with respect to the time at which the user wishes to arrive at the destination by vibration of the vibration unit 10 or light of the light emitting unit 7 and displayed on the display unit 5. The navigation assistance performed based on the map information and the voice guidance sounded through the speaker unit 3 can be performed.

In the description of the second embodiment described above, the auxiliary operation is performed according to two factors: “distance to the destination” and “time difference between the time desired to arrive at the destination and the current time”. The target for performing the auxiliary operation is controlled based only on the “time difference between the time when the user wishes to arrive at the destination and the current time”. Also good. In this case, the target to perform the auxiliary operation is controlled according to the time difference (remaining time) between the current time and the desired destination arrival time. Therefore, the user can take actions according to the remaining time, such as speeding up walking or using transportation such as taxis, buses, trains, etc., and arriving at the destination by the desired time Can be made possible.

[Modification]
In each of the above-described embodiments, the target to be assisted is driven and controlled according to the “distance to the destination”, or the “distance to the destination” and the “desired arrival time and the current time” The target to perform the auxiliary action according to the time difference with the drive control is performed, but this calculates the “movement pace” by calculating the distance moved within a certain time, and this movement pace , "Is the pace suitable for arriving at the destination at the desired arrival time?", "Is it better to increase the pace to arrive at the destination at the desired arrival time?" It may be possible to notify the user through the subject to perform the assisting action “whether it is better to slow down to arrive at the ground”.

  In this case, the user sets the destination as described in the first embodiment and sets the desired arrival time for the destination as described in the second embodiment. Then, the start of navigation to the destination is specified. Thereby, the flowchart of FIG. 6 is started.

  In the flowchart of FIG. 6, the control unit 13 acquires the current position detected by the GPS unit 9 in step S41, and acquires the current time counted by the timer 11 in step S42. In step S43, it is determined whether or not a predetermined time such as 1 minute has elapsed since the current position was acquired.

  For example, when a predetermined time such as 1 minute elapses after acquiring the current position, the control unit 13 acquires the current position detected by the GPS unit 9 again in step S44. In step S45, by calculating the distance moved in one minute, the moving pace for one minute is calculated.

  Next, in step S46, the control unit 13 can arrive at the destination at the desired arrival time set by the user when the current position and the distance to the destination are moved at this moving pace. Determine whether or not. If it is determined that the destination cannot be reached at the desired arrival time when moving at the moving pace, the control unit 13 returns to the destination earlier than the desired arrival time when moving at the moving pace in step S49. Determine whether or not to arrive.

  In each determination step of step S46 and step S49, the control unit 13 moves from the current position to the destination by dividing the remaining distance from the current position to the destination by the distance moved in the one minute. Whether the time required for the time (required time) is calculated and the time obtained by adding the required time and the current time is the desired arrival time set by the user (whether it is within a predetermined time error range) This is done by determining. When it is determined that the user arrives at the destination at the desired arrival time by moving at the moving pace (when the calculated estimated arrival time and the desired arrival time are within a predetermined time error range). ), The controller 13 advances the process to step S47. If it is determined that the user arrives at the destination at a time earlier than the desired arrival time by moving at the moving pace, the control unit 13 advances the process to step S50, and moves at the moving pace. If it is determined that the user arrives at the destination at a time later than the desired arrival time, the control unit 13 advances the process to step S51.

  In step S47, since the vehicle can reach the destination at the desired arrival time when moving at the above moving pace, the control unit 13 in step S47, the vibration unit 10 or the light emitting unit 7 designated in advance by the user. The control target such as is driven with the reference pattern. As a result, the user can recognize that the vibration unit 10 or the like is driven with the reference pattern, so that the user arrives at the destination at the desired arrival time if the user moves at this pace.

  On the other hand, when moving at the above-mentioned movement pace, when arriving at the destination earlier than the desired arrival time, the control unit 13 determines whether the vibration unit 10 or the light emitting unit designated in advance by the user in step S50. The control target such as 7 is driven with a drive pattern instructing pace down, such as driving with a slower pattern than the reference pattern. As a result, the user recognizes that the vibration unit 10 and the like are driven with a drive pattern slower than the reference pattern, so that the user arrives at the destination earlier than the desired arrival time if the user keeps moving at this pace. It is possible to reduce the pace of movement, such as walking a little more slowly.

  In addition, when moving at the above moving pace, when arriving at the destination later than the desired arrival time, the control unit 13 determines whether the vibration unit 10 or the light emitting unit 7 or the like designated in advance by the user in step S51. The control target is driven and controlled with a drive pattern instructing pace-up, such as driving the control target with a pattern earlier than the reference pattern. As a result, the user recognizes that the vibration unit 10 and the like are driven with a driving pattern earlier than the reference pattern, so that the user arrives at the destination later than the desired arrival time if the user moves at this pace. It is possible to increase the pace of movement such as increasing the walking speed.

The drive control of the control target according to such a moving pace is performed until the control unit 13 detects a navigation end operation performed by the user or detects that the user has reached the destination in step S48. Will be executed repeatedly.
