Japanese Patent Laid-Open No. 2002-236031

  However, this type of navigation function is only an additional or secondary function compared to basic functions such as a call function and an e-mail function for a mobile phone. It is necessary to perform a series of operations (menu selection operations) according to the procedure, which puts a burden on the user, and the navigation function cannot be activated while the vehicle is inoperable (during driving).

  An object of the present invention is to enable a navigation function to be activated in accordance with the movement state of the apparatus main body without performing a special key operation such as a menu selection operation.

The invention according to claim 1 is a portable terminal device having a navigation function for acquiring the current position and performing guidance according to the current position, and detecting means for detecting whether or not the device body is moving Further, it is characterized in that it comprises function selecting means for preferentially selecting and activating the navigation function when it is detected by the detecting means that it is moving.
Furthermore, a program for realizing the main functions shown in the invention described in claim 1 is provided to the computer (the invention described in claim 7).

The invention described in claim 1 described above may be as follows.
The navigation function includes a navigation function for pedestrian support and a navigation function for vehicle support, and the function selection means determines whether the apparatus main body is moving, whether it is a walking movement state or a vehicle movement state, and walks and moves When the vehicle is in a state, the navigation function for supporting the pedestrian is selected, and when the vehicle is in a moving state, the navigation function for supporting the vehicle is selected (invention of claim 2).

  In this case, it is determined whether the walking movement state or the vehicle movement state during the operation of one of the navigation function for pedestrian assistance or the navigation function for vehicle assistance, and the walking movement during the operation of the navigation function for vehicle assistance is performed. When the state changes, a navigation function for supporting pedestrians may be selected (the invention according to claim 3).

  Whether the walking movement state or the vehicle movement state is determined on the basis of the degree of change in the current position of the apparatus main body (the invention according to claim 4).

  Having a plurality of application functions other than the navigation function, and receiving a selection instruction for any one of the application functions, the function selection means preferentially selects the navigation function if the apparatus main body is moving (Invention of Claim 5)

The invention according to claim 6 is a portable terminal device having a navigation function for pedestrian support and a navigation function for vehicle support as a navigation function for obtaining a current position and performing guidance according to the current position, When route guidance to a destination is performed by the navigation function for vehicle assistance, it is detected whether or not the destination coincides with the current position when an instruction to end the navigation function is received. It is characterized by comprising detection means and activation means for selectively activating the navigation function for supporting pedestrians when a mismatch between the destination and the current position is detected by the detection means.
Furthermore, a program for realizing the main functions shown in the invention described in claim 6 is provided to the computer (the invention described in claim 8).

  According to the first aspect of the present invention, it is detected whether or not the apparatus main body is moving, and if it is moving, the navigation function is selected and activated with priority. The navigation function can be activated in conjunction with the movement of the apparatus main body without performing any key operation, thereby reducing the burden on the user and contributing to safe driving.

  According to the invention described in claim 2, in addition to having the same effect as that of the invention described in claim 1 described above, when the apparatus main body is moving, it is determined whether it is a walking movement state or a vehicle movement state, and the walking movement state is established In some cases, the navigation function for pedestrian support is selected, and when the vehicle is in a moving state, the navigation function for vehicle support is selected. It is possible to switch between the navigation function for vehicle support and the navigation function for pedestrian support according to the moving state of the vehicle, continuously switching from vehicle support to pedestrian support, or continuously from pedestrian support to vehicle support. It is possible to switch, and it is possible to smoothly perform the switching that can improve convenience.

  In this case, since the navigation function for supporting the pedestrian is selected when the vehicle changes to the walking movement state during the operation of the navigation function for supporting the vehicle (invention according to claim 3), for example, the vehicle moves The route from the parking point to the destination walks even if the destination arrives at the destination, but the parking lot is crowded and you have to park elsewhere or the parking lot is far away Because it is guided by the person who supports you, you can head to the destination without getting lost.

  According to the invention of claim 4, in addition to having the same effect as the invention of claim 1 described above, it is determined whether the walking movement state or the vehicle movement state based on the degree of change of the current position of the apparatus main body. Therefore, for example, it is possible to determine the movement state of the apparatus main body simply by acquiring the current position every predetermined time to obtain a position change per unit time or by installing a speed sensor or the like.

  According to the invention described in claim 5, in addition to having the same effect as the invention described in claim 1 described above, it has a plurality of application functions other than the navigation function, and has received an instruction to select one of these application functions. At this time, if the device body is moving, the navigation function is preferentially selected. Therefore, when the navigation function is highly available, the navigation function is given priority over application functions such as music playback. Selective activation is possible.

  According to the sixth aspect of the present invention, when route guidance to the destination is performed by the vehicle support navigation function, the destination and the current position are received when an instruction to end the navigation function is received. If a mismatch between the destination and the current position is detected, the navigation function for pedestrian support is selectively activated. It is possible to smoothly switch from the navigation function for vehicle support to the navigation function for pedestrian support without performing any key operation.

Example 1
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to a mobile phone device with a GPS function as a mobile terminal device. FIG. 1 shows a navigation that performs a location information service (navigation service) using a mobile phone device with a GPS function. It is the block diagram which showed the system.
This navigation system provides a location information service that displays a current position on a map and provides route guidance to a destination. A mobile phone device 1 with a GPS function includes a mobile communication network (mobile phone network) 2. Are connected to the server device 3 on the content provider side and connected to the Internet 4. The content provider provides various location information services such as a navigation service and a town information service.

  The cellular phone device 1 is, for example, a foldable device in which two housings are attached so as to be openable and closable, and includes a navigation function in addition to a telephone function (call function), a mail function, and an Internet connection function. This navigation function obtains the current position using the GPS satellite 5, displays the current position on a map, provides route guidance to the destination, and provides voice guidance such as the traveling direction. The apparatus 1 has a navigation function for supporting pedestrians that provides route guidance to pedestrians and a navigation function for supporting automobiles that provides route guidance to the automobile 6.

FIG. 2 is a block diagram showing basic components of the mobile phone device 1 with a videophone function.
The CPU 11 is a central processing unit that controls the overall operation of the mobile phone device 1 in accordance with various programs in the storage unit 12. The mobile phone device 1 may have a configuration in which a plurality of CPUs are provided for each function. The storage unit 12 is a non-volatile memory (internal memory), and includes, for example, a flash memory and has a program area and a data area. The program area includes a navigation program for assisting pedestrians and an automobile support. In addition to the navigation program, various programs such as a program for realizing the present embodiment in accordance with an operation procedure shown in FIG. 3 to be described later are stored. The recording medium 13 is a detachable portable memory that supplies photographed image data, various types of data, and programs to the outside. The recording medium 13 includes, for example, smart media and an IC card. The memory 14 is an internal memory having a work area, and includes, for example, a DRAM (Direct Random Access Memory), an SDRAM (Synchronous DRAM), or the like.

  The telephone communication unit 15 includes a communication unit, a baseband unit, a demultiplexing unit, and the like. After receiving a signal from the reception side of the transmission / reception duplexer connected to the antenna 15A and demodulating it into a reception baseband signal, The sound is output from the audio speaker 17 via the control unit 16. Further, the telephone communication unit 15 takes in the audio data input from the audio microphone 18 from the audio control unit 16, encodes it into a transmission baseband signal, gives it to the transmission side of the transmission / reception duplexer, and transmits it from the antenna 15A. . On the other hand, the display data received and acquired through the telephone communication unit 15 by the e-mail function, navigation function, and Internet connection function is given to the main display unit 20 having an LCD (liquid crystal display device) or the like through the display control unit 19. Is displayed and output.

  The main display unit 20 displays map information for route guidance, character information, various messages, and the like with high quality. A sub-display unit 21 is provided on the back surface of the apparatus main body. The sub-display unit 21 displays the current date and time, a simple message, an icon, and the like. The key operation unit 23 performs dial input, character input, command input, and the like, and the CPU 11 executes processing according to a key input signal from the key operation unit 23. The notification unit 24 includes a speaker for notification of incoming calls, an LED (light emitting diode), and a vibration motor. The notification unit 24 performs incoming call notification when an incoming call / mail is received or is also driven when an alarm is notified. The GPS receiving unit 25 uses a GPS satellite and a ground control station to receive a current position (longitude and latitude) that is strictly measured from the difference in arrival times of radio waves from a plurality of satellites. The current user position (position of the apparatus main body) is monitored while receiving and acquiring the GPS measurement position by accessing the receiving unit 25.

  In this case, the CPU 11 calculates a position change per unit time based on the current position for each fixed time obtained by the GPS receiver 25, and determines whether or not the apparatus main body is moving based on the position change. If it is currently moving, the navigation function is preferentially selected and activated. In this case, it is determined whether the vehicle is moving by walking or walking based on the degree of position change, and if it is walking, the navigation function for pedestrian support is selected. If it is in the middle, the navigation function for supporting the car is selected.

  Next, the operation concept of the mobile phone device in the first embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in this flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment.

FIG. 3 is a flowchart mainly showing operations related to a navigation function for assisting automobiles as operations of the mobile phone device which are started to be executed when the power is turned on.
First, the CPU 11 reads out a predetermined standby image in the standby state, displays and outputs it (step A1), checks whether there is an incoming call or mail (step A2), and detects an incoming call or incoming mail. In addition to driving the notification unit 24 by executing the process, a call process or a received mail storage process is executed (step A3). If any key operation is performed (YES in step A4), it is checked whether an application key that calls an application function (for example, mail creation processing, Internet connection processing, music playback processing, etc.) is operated. If it is a key operation other than the application key (step A5), for example, a data input process or the like is executed as a process corresponding to the operation key (step A6), and the process returns to the standby state (step A1).

  Here, when the application key is operated (YES in step A5), the current position is acquired from the GPS receiver 25 and the degree of position change is measured (step A7), and it is determined whether or not it is moving. (Step A8). For example, in the state where the current position is acquired every second and the position information for 10 seconds is sequentially stored, is the apparatus main body stationary by analyzing the position information 10 seconds before when operating the application key? Guess if moving. As a result, if the apparatus main body is stationary (NO in step A8), the application menu is displayed in response to the operation of the application key (step A9), and then an arbitrary menu is selected from the menu screen by the user operation. When an item is selected and specified (step A10), an application program corresponding to the selection menu is started (step A11), and the application process is executed (step A12). Then, it returns to a standby state (step A1).

  On the other hand, if the apparatus main body is moving (YES in step A8), a confirmation message for inquiring whether to activate the navigation function is notified (display output and voice output) (step A13). In response to this confirmation message, it is checked whether or not a navigation function activation request is instructed by the user (step A14). If there is no activation request, the process proceeds to the application menu display process described above (step A9). If it is detected, it is determined whether or not the vehicle is moving at high speed with reference to the above-described degree of position change (step A15). That is, it is determined whether the vehicle is moving at a high speed (for example, 10 km / h or more) or is moving at a low speed (less than 10 km / h).

  If the vehicle is moving at high speed (YES in step A15), it is recognized that the vehicle is moving, and a navigation function (car navigation) for supporting the vehicle is selected and activated (step A16). In this case, the navigation processing is executed while receiving the map information corresponding to the current position from the server device 3 on the content provider side, the current position is displayed on the map, the route guidance to the destination is performed, the traveling direction, etc. Voice guidance is performed (step A17). Even during the execution of this navigation process, the current position is acquired from the GPS receiver 25 and the degree of position change is measured (step A18). In this case, it is determined whether or not the vehicle has moved from high-speed movement to low-speed movement, that is, whether the vehicle movement has changed to walking movement (step A19). This navigation process is continued (step A17) until the end is instructed (step A22).

  Now, when the vehicle changes to low speed movement (walking movement) during car movement (car navigation operation) (YES in step A19), a confirmation message for inquiring whether to activate the navigation function for pedestrian support is displayed. Notification (display output and audio output) is performed (step A20). In response to this confirmation message, it is checked whether or not a navigation function activation request is instructed by the user (step A21). If there is no activation request, the operation is continued until the car navigation ends (step A22). In this case, a navigation function for supporting pedestrians is selectively activated instead of navigation for supporting cars (step A23). On the other hand, when it is determined that the vehicle is moving at a low speed in step A15 described above, the process moves to step A23 to selectively activate the navigation function for supporting pedestrians.

  In this case, navigation processing is executed while downloading the map information for the pedestrian corresponding to the current position from the server device 3 on the content provider side by starting the navigation function for pedestrian support, and the current position is displayed on the map. Route guidance to the destination (the destination inherited from the car navigation system) and voice guidance such as the traveling direction are performed (step A24). Thereafter, the navigation processing is continued (step A24) until a navigation end instruction or destination arrival by a user operation is detected (step A25).

  As described above, in the first embodiment, the CPU 11 calculates the position change per unit time based on the current position for each fixed time obtained by the GPS receiver 25, and the apparatus main body is based on the position change. It is determined whether or not it is moving, and if it is moving, the navigation function is selected and activated with priority, so that it does not perform special key operations such as menu selection operations, and is linked to the movement of the device body. Thus, the navigation function can be activated, so that the burden on the user can be reduced and the vehicle can contribute to safe driving.

  Here, when the device body is moving, it is determined whether the vehicle is moving or walking based on whether it is moving at low speed or high speed. In the case of low speed movement, a navigation function for supporting pedestrians is selected and high speed movement is selected. In the case of movement, since the navigation function for automobile support is selected, it is possible to switch between the navigation function for automobile assistance and the navigation function for pedestrian assistance without any special operation. It is possible to continuously switch from automobile support to pedestrian support, and it is possible to smoothly perform the switching that can improve convenience. For example, even if you arrive at your destination by moving a car, but have a parking lot and you have to park elsewhere or if your parking lot is far away, The route is guided by pedestrian support, so you can head to your destination without getting lost.

  Further, since the CPU 11 preferentially selects the navigation function if the apparatus main body is moving when the application key is operated, the music playback is performed while the navigation function is highly available. The navigation function can be selected and activated in preference to the application function.

In the first embodiment described above, a position change per unit time is calculated based on the current position for each fixed time obtained by the GPS receiver 25, and whether the apparatus main body is moving based on this position change. However, a speed sensor may be provided to determine whether or not the apparatus is moving based on the vibration state of the apparatus main body.
(Example 2)

A second embodiment of the present invention will be described below with reference to FIGS.
In the first embodiment described above, it is determined whether the vehicle is being used (whether the apparatus main body is moving) based on the degree of change in position. However, in this second embodiment, driving in the vehicle is performed. Based on whether or not the device main body is connected to a hands-free device provided in the vicinity of the seat, it is determined whether the vehicle is used (whether or not the device main body is brought into the vehicle). In this case, in the first embodiment, the navigation function for supporting the pedestrian is activated instead of the navigation function for supporting the car when the vehicle changes to the low speed movement during the operation of the navigation function for supporting the car. In the second embodiment, when the connection with the hands-free device is released during the operation of the navigation function for automobile support, the navigation function for pedestrian assistance is activated instead of the navigation function for automobile assistance. Is.
Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

  FIG. 4 is a diagram showing an example of a navigation screen displayed on the main display unit 20 in a state where the foldable apparatus main body is opened and the lower housing thereof is inserted and connected into the hands-free connector 7A. The hands-free connector 7A includes a hands-free device 7 (sound speaker 7B, sound microphone 7C, control unit 7D) attached to the vicinity of a driver's seat in an automobile, for example, a sun visor, and a connector portion on the mobile phone device 1 side. 22 is connected to the front passenger seat near the windshield, and when the mobile phone device 1 is placed, the navigation screen is directed to the driver side. ing.

  The hands-free connector 7A is provided with a locking portion (not shown) for freely attaching and detaching the mobile phone device 1, and the mobile phone device 1 is inserted and connected to the connector portion 22 thereof. Then, the hands-free connector 7 </ b> A operates the aforementioned locking portion to fix the lower housing of the mobile phone device 1. In this state where the cellular phone device 1 is fixed, a part (part of the operation surface) of the lower casing protrudes from the hands-free connector 7A, and the keys on the operation surface can be operated. Yes. The mobile phone device 1 and the hands-free device 7 are not limited to being connected by wire, and may be wirelessly connected. Based on whether or not the mobile phone device 1 is electrically connected to the hands-free device 7, the CPU 11 detects whether or not the device main body has been brought into the automobile. The support navigation function is selectively activated.

FIG. 5 is a flowchart showing mainly operations related to a navigation function for automobile support as operations of the mobile phone device in the second embodiment.
First, the CPU 11 reads out a predetermined standby image in the standby state, displays it and outputs it (step B1), checks whether or not a telephone call or mail has arrived (step B2), and detects an incoming call or incoming mail. In addition to driving the notification unit 24 by executing the process, a call process or a received mail storage process is executed (step B3).

  Here, it is detected whether or not the apparatus main body is inserted and connected to the hands-free connector 7A (step B4). Here, as shown in FIG. 4, when the user opens the foldable apparatus main body and inserts the lower housing into the hands-free connector 7A, the connection is established from the hands-free connector 7A via the connector portion 22. Since the signal is input, the CPU 11 detects whether or not the apparatus main body has been brought into the vehicle based on the connection presence signal. As a result, if it is not connected to the hands-free device 7, it returns to the standby state (step B1).

  If it is connected to the hands-free device 7, it is recognized that the device body has been brought into the car, and the process proceeds to step B5 to determine whether application processing such as music playback processing is being executed, If it is being executed, a confirmation message for inquiring whether or not to activate the navigation function for automobile support is notified (display output and voice output) (step B6). In response to this confirmation message, it is checked whether a navigation function activation request is instructed by the user (step B7). If there is no activation request, the process returns to a standby state (step B1). A navigation function for supporting a car is selected and activated (step B8). In this case, the navigation processing is executed while receiving the map information corresponding to the current position from the server device 3 on the content provider side, the current position is displayed on the map, the route guidance to the destination is performed, the traveling direction, etc. Voice guidance is performed (step B9).

  During such navigation processing, the CPU 11 checks whether or not the connection with the hands-free device 7 has been detected (whether the connection with the hands-free device 7 has been released) (step B10). The navigation process is continued as it is (step B9), but if disconnection is detected, the navigation process for car assistance (car navigation process) is terminated (step B11). In this case, it is checked whether or not the vehicle has arrived at the destination by comparing the current position with the destination (step B12). Here, if the vehicle has arrived at the destination, it returns to the standby state (step B1), but if the route is being guided and has not arrived at the destination (NO at step B12), it replaces the navigation for automobile support. Then, the navigation function for supporting the pedestrian is selected and activated (step B13).

  In this case, the navigation processing is executed while receiving the map information for the pedestrian corresponding to the current position from the server device 3 on the content provider side, and the current position is displayed on the map to display the destination (the destination taken over from the car navigation system). ) And voice guidance such as the direction of travel (step B14). Thereafter, it is checked whether or not the destination has arrived (step B15), and the navigation process is continued by returning to step B14 until the destination has arrived. And when arriving at a purpose etc., after finishing the navigation process for pedestrian support (step B16), it will be in a standby state (step B1).

  As described above, in the second embodiment, the CPU 11 detects whether or not the apparatus main body has been brought into the automobile based on whether or not the apparatus main body is connected to the hands-free device 7 installed in the automobile. However, when it is brought into the car, a navigation function for supporting the car is selectively activated, and when the connection with the hands-free device 7 is released and the device body is taken out of the car, walking Since the navigation function for pedestrian support is selectively activated, it is possible to switch between the navigation function for car support and the navigation function for pedestrian support without any special operation. It becomes possible to raise. For example, if you have arrived at your destination but have a parking lot and you have to park in another location, or if your parking lot is far away, the route from the parking location to your destination will be supported by pedestrians. You will be guided to the destination without getting lost.

  In this case, in a state where the apparatus main body is brought into the vehicle and connected to the hands-free device 7, during application processing such as music playback, whether the function is activated before the navigation function is selected and activated. A confirmation message for inquiring whether or not is issued, and in response to receiving an activation request instruction, the navigation function is activated, so the navigation function is activated with the user's consent. be able to.

  In the second embodiment described above, it is detected whether or not the apparatus main body has been brought into the vehicle based on whether or not it is connected to the hands-free device 7. Not limited to this, it may be detected whether or not the apparatus main body is brought into the vehicle based on whether or not the apparatus main body is inserted or connected to a vehicle-mounted audio device or charging device.

Moreover, you may make it discriminate | determine that the apparatus main body was carried in in the motor vehicle by detecting the engine sound of a motor vehicle. That is, the CPU 11 performs volume analysis and frequency analysis on the input sound from the voice microphone 18 and determines whether or not the apparatus main body has been brought into the vehicle based on whether or not engine sound with a predetermined volume or higher has been detected. You may make it discriminate | determine. In addition to the detection of engine sound, it may be determined whether or not the apparatus main body has been brought into the vehicle based on the recognition result of the outside world such as ambient illuminance and image analysis taken by the camera.
In the second embodiment described above, the navigation function may be terminated not only at the time of getting off, but also when a certain time has elapsed after getting off (for example, when 3 minutes have passed).

In the first and second embodiments described above, the navigation process for supporting the vehicle is continuously switched to the navigation process for supporting the pedestrian. On the contrary, the navigation for supporting the pedestrian is performed. You may make it switch continuously from a process to the navigation process for motor vehicle assistance. In the first and second embodiments described above, the incoming call during the navigation process is not mentioned. However, when the incoming call is detected during the navigation process, the CPU 11 temporarily performs voice guidance as the navigation. Although it is interrupted, the route guidance for displaying the current position on the map while executing the incoming call processing may be continued as it is.
In addition, the present invention is not limited to the mobile phone device, and can be similarly applied to a mobile terminal device such as a PDA with a GPS function, an electronic camera, an electronic wristwatch, or a music player.
