DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording apparatus capable of recording a voice in association with a utterance (utterance) location and time.

[0002]

2. Description of the Related Art Conventionally, an on-vehicle navigation device is provided to a driver on the basis of a current position of a vehicle received from a GPS (Global Positioning System) receiver to display a map around the vehicle, thereby giving a driver a traveling position of the vehicle. The main operation is to inform the driver of a destination and to provide a route guidance to a destination set by the driver, and to provide a function as a map display device for displaying a map around the vehicle.

[0003] Such a navigation device is provided with various functions. For example, when a user registers a predetermined point in advance, a user can display a peripheral map of the point by a simple button operation. With the same simple operation, the point can be set as the destination and the navigation device can guide the route to the destination. In a navigation device having such a function,
Along with the setting of the point, it is configured to be able to enter characters representing the point by key operation, for example, when finding a favorite store, the user can enter the name of the store in characters, When visiting the store later, the location can be confirmed on a map, and the navigation device can guide the route to the store by a simple operation.

On the other hand, in a navigation device designed for home delivery and collection / delivery work, the time of visit to each home is recorded, and the purpose of visit is selected and recorded from a pre-registered list. Some functions can be performed, and the user can create a business log on the navigation device using such a function. In addition, there is a navigation device that acquires detection data of various sensors in the vehicle and stores the data as a history, and the user can utilize these data for the purpose of vehicle operation management.

[0005]

However, the prior art described above is inconvenient in the following points. For example, when a user registers a favorite place, the user must express the contents related to the place with several characters of information. For example, when registering a store, the name of the store or the store Could only be registered. In other words,
Since the user cannot store the detailed contents of the registered point in the navigation device, after the user's memory becomes ambiguous, whether the registered point has any information or whether it is a store or not. I had no idea what the atmosphere was like.

[0006] In the navigation device for business use, the user simply selects and records the corresponding visit purpose from the categorized list by key operation. In the case where a business log is created by recording a document, the contents must be written down in a notebook or the like by hand.

[0007] Further, since the keys must be operated when using the above functions in these navigation devices, the user needs to stop the vehicle once and write the contents to be recorded to the navigation devices unless the vehicle is once stopped. I couldn't keep a record. In addition, since the data detected from each sensor in the vehicle that can be automatically recorded indicates only an event related to the traveling state of the vehicle, the user should carefully record the event that occurs due to human factors. Could not.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and has as its object to provide an information recording apparatus having a function of recording a desired voice content in association with a utterance (utterance) position. I do.

When the information recording device is mounted on a vehicle or the like, the device is provided with a moving route storage means for storing the history of the user's moving route by acquiring the current position from the current position specifying means. It is preferable that the display unit displays the history of the movement route so as to be superimposed on the map image. In this way, the user can confirm how the user has moved and then stored the voice, and can easily understand the voice content later when inputting the content related to the travel route by voice. can do.

[0016] On the other hand, the above information recording apparatus is characterized in that
As described in claim 8, the notification control unit may be configured to notify the notification unit of the corresponding voice based on a display selection instruction in a form in which the presence of the voice input can be visually recognized. In this way, the user can not only check the recorded audio content with the information recording device, but also can easily recognize the audio content and the recording position in association with each other.

Further, in the information recording apparatus according to the present invention, the notification control means notifies the notifying means of time information related to the stored sound in addition to the stored voice. With this configuration, the user can confirm the recording time together with the audio content. In this case, since the user can confirm the recording time by voice, there is no need to watch the display screen or the like of the information recording device to confirm the recording time when the user is moving. It is convenient. The notification control means may notify the time information before and after notifying the stored voice content based on the user's selection instruction, or may use the time information without cooperating with the notification of the stored voice content. When a command is input from the user, only the time information of the selected audio content may be notified.

In addition, in the information recording apparatus according to the third or fifth to ninth aspects, when a plurality of storage target voices are stored in the storage means, the information recording apparatus may be configured as described in the tenth aspect. Then, the display control means causes the display means to display a list of each input voice, and when the input voice is selected from the list by the user, the presence of the voice is visually recognized with respect to the input voice. The display may be configured to be displayed on the display unit together with the map image at a portion indicating the current position. In this way, even if there are a plurality of voices to be stored, the user can easily confirm the recording position (utterance location) of the input voice at the display position.

Thus, it is possible to perform various settings related to the functions provided in the navigation device 1 (including functions unique to the navigation device 1 of the present embodiment).

That is, the navigation device 1 of the present embodiment
Then, on the menu screen, a "voice recording switch" for setting the voice memo function for recording the voice of the vehicle occupant from the microphone 29a to be enabled (ON) or disabled (OFF), and a mobile phone call A "call recording switch" for setting the call recording function for recording to either useable (ON) / disablement (OFF), and a travel route storage function for recording the history of the travel route of the vehicle (ON) ) / "Route route storage switch" for setting to either use (OFF), display a list of various data stored in the device by using these functions, and select data from the list Then, a "history display switch" for causing the control unit 41 to execute the history display processing is displayed, and the vehicle occupant touches each of the displayed switches to turn on / off the switches. By such switching the FF, can be made as to whether the setting or the like to use the functions specific to those of the navigation device 1.

For example, when a vehicle occupant touches and turns on a travel route storage switch displayed on a menu screen,
The control unit 41 executes a traveling route storage process shown in a flowchart in FIG. That is, when the travel route storage switch is turned on, the control unit 41 determines in S110 that the position detection unit 1
The information on the current position is acquired from each of the sensors 0 and the current position of the vehicle determined from the information is stored.

Next, in S120, the control unit 41
The display unit 25 determines whether or not the map screen is displayed, and if it is displayed (Yes in S120), S
At 130, the history of the current position of the vehicle stored in the previous process of S 110 and the current position stored at this time of S 110 are stored along the road on the map screen displayed on display unit 25. The history of the running route of the vehicle up to the present (hereinafter referred to as “running history”) is displayed on the map screen by connecting with colored lines (thick line in the display unit 25 shown in FIG. 2). On the other hand, if the control unit 41 determines in S120 that the map screen is not being displayed, the process proceeds to S140 without performing the process of S130.

Thereafter, the control unit 41 determines in S140 whether or not the vehicle has traveled a predetermined distance from the acquired current position (S110) based on the vehicle position information acquired from the distance sensor 13 or the like of the position detection unit 10. If it has proceeded the predetermined distance (Yes in S140), the process returns to S110. On the other hand, if the vehicle has not progressed the predetermined distance (N in S140)
o), the control unit 41 shifts the processing to S150, determines whether or not the vehicle occupant has turned off the travel route storage switch on the menu screen, and ends the processing if it has been turned off (Yes in S150), If it remains ON (S
(No in 150), the process returns to S140.

By performing such processing, the navigation device 1 can leave a history of the route on which the vehicle has traveled, and the driver can manage the traveling history of the vehicle. In order to make it easier for the vehicle occupant to manage the travel history, the travel history data in the navigation device 1 of the present embodiment is divided into days and divided by the control unit 41.
Is stored in the RAM.

Next, the processing related to the voice memo function and the call recording function will be described with reference to FIG. FIG. 4A is a flowchart showing the voice memo processing.
(B) is a flowchart showing a call recording process.
The voice memo processing shown in FIG. 4A is executed by the control unit 41 when the "voice recording switch" on the menu screen is turned on and the voice memo function is set to be usable. When the vehicle occupant presses the voice recognition button 27b and utters “memo” into the microphone, the control unit 41 executes this process on the assumption that the vehicle occupant has issued a voice recording command.

That is, when executing the voice memo processing, the control unit 41 first obtains the current position of the vehicle from the position detection unit 10 in S210 and stores this current position as a recording position. The time at that time (hereinafter, referred to as a recording time) is obtained from the internal clock provided in the device and stored. Note that the recording time includes the date.

Next, in S220, the control section 41 announces to the vehicle occupant from the speaker 31a of the audio output section 31 by voice that "recording preparation is completed" and confirms that the voice is being recorded. The indicated recording mark (not shown) is displayed on a peripheral map corresponding to the stored recording position.

Thereafter, in S230, control unit 41 converts the sound input from microphone 29a of sound input unit 29 into RA.
The sound is recorded while being stored in M, and in S240, the microphone 29a
This operation is continuously performed until it is determined that the voice of “memo ending” is input from the vehicle occupant (Yes in S240). Since it is conceivable that the vehicle occupant may forget the voice operation of “Memo end”, the control unit 41 in the present embodiment determines in S240 that a predetermined time elapses after the voice is no longer input from the microphone 29a. It is determined that the memo is over (Yes in S240).

When the control section 41 determines that the command to end the memo is given by the vehicle occupant in S240, the control section 41 proceeds to S2
At 50, the stored voices are combined into voice data, which is stored in the RAM in association with the recording position and the recording time stored at S210, and the voice data is stored unless a command to delete from the vehicle occupant is input. Make it undeletable.

Thereafter, the control section 41 controls the display section 25 in S260 to display a voice mark 43 indicating the recording position on the map screen instead of the recording mark, and the voice mark 43 Is displayed next to (the display unit 25 shown in FIG. 2), and the voice memo processing is ended.

In the navigation device 1, a map screen is usually displayed on the display unit 25. However, when a menu screen or the like is displayed and the map screen is not displayed in exceptional cases, the control unit 41 is displayed. Controls the display unit 25 to display the surrounding map screen (that is, shift to the map display mode), and displays the voice mark 43 on the map screen.

On the other hand, the call recording process shown in FIG.
This is executed by the control unit 41 when the “call recording switch” on the menu screen is turned on and the call recording function is set to be usable, and the vehicle occupant is connected to the portable device connected to the navigation device 1. By operating the telephone 35 to switch the mobile phone 35 from the non-calling state to the talking state,
The control unit 41 executes this processing assuming that the call has started.

That is, after executing the call recording process, the control unit 41 first acquires the current position of the vehicle from the position detection unit 10 in S310, stores this current position as the call recording position, and (Hereinafter referred to as a call recording time). Then, the control unit 41 proceeds to S32
At 0, recording of the content of the call received as a voice signal from the mobile phone 35 is started, and until the mobile phone 35 is switched from the call state to the non-call state at S330, and it is determined that the call is terminated (Yes at S330). , The contents of the call are continuously recorded in the RAM. In this case, similarly to the voice memo processing, a recording mark indicating that the content of the call is being recorded is displayed at the call recording position on the map screen.

When the control section 41 determines in S330 that the call has ended (Yes in S330), the control section 41 proceeds to S34.
At 0, it is determined whether or not a command to save this call content has been input from the vehicle occupant. That is, the control unit 41
In S340, after announcing "Do you need to save the contents of the call?" By voice, the voice recognition button 27b is pressed within a predetermined time and the voice of "necessary" is
It is determined whether or not the input has been made from 9a. If the input has been made, it is determined that a command to save the call content has been issued from the vehicle occupant, and the process proceeds to S350.

In S350, the control unit 41 associates the voice data recording the content of the call with the call recording position and the call recording time stored in S310,
And cannot be deleted unless there is a command from the vehicle occupant. Thereafter, in S360, control unit 41 displays telephone mark 45 indicating the call recording position on the map screen (see display unit 25 shown in FIG. 2), and ends the call recording process. The processing when the map screen is not displayed on the display unit 25 is the same as the voice memo processing.

On the other hand, if the control unit 41 determines in S340 that the command to save the call content has not been input from the vehicle occupant, the control unit 41 discards the recorded call content in S370, and ends the processing. Next, the reproduction process executed by the control unit 41 when the voice mark 43 and the telephone mark 45 on the map screen shown in FIG. 2 are touched by the vehicle occupant will be described. This reproduction process is a process for reproducing the audio data stored in the navigation device 1, and FIG. 5 is a flowchart showing the reproduction process.

As shown in FIG. 5, when the voice mark 43 or the telephone mark 45 (hereinafter simply referred to as "mark") is touched by the vehicle occupant (that is, when the mark is selected), the control unit 41. Performs a reproduction process, and in S410, notifies the recording time or call recording time of the voice data corresponding to the touched mark (hereinafter, these are referred to as “recording times”) by voice.

Next, the control unit 41 determines in S420
The recorded contents or call contents (hereinafter, referred to as "recorded contents") recorded as the sound data are reproduced, and the sound is output from the speaker 31a. Then, when the reproduction ends, the control unit 41 proceeds to step S430.
An announcement “Delete?” Is issued from the speaker 31a, and it is determined whether or not an instruction to delete data is input from a vehicle occupant within a predetermined time after the announcement.

That is, the control section 41 determines whether or not the vehicle occupant has pressed the voice recognition button 27b and input a voice of "delete" from the microphone 29a within a predetermined time after the announcement, If it has been input, it is determined that a command to delete data has been issued from the vehicle occupant (Y in S430).
es), the data is deleted (S440). On the other hand, if the voice of “deletion” is not input within the predetermined time, the control unit 41 ends the reproduction process without deleting the data.

Therefore, by using the navigation device 1 of the present embodiment, the vehicle occupant can not only save the recorded voice together with the position information but also visually confirm the recorded position on the map screen. Further, the sound can be reproduced only by touching the sound mark 43, so that the recording position and the content of the recorded sound can be easily associated and grasped.

In other words, for example, when a vehicle occupant finds a good restaurant or the like during a drive, he or she can record the details of meals and the like at that restaurant in detail by voice. Even when the memory becomes ambiguous, by listening to the voice, it is possible to easily recall what kind of atmosphere the restaurant was like.

Also, if the vehicle occupant records the impression at the scenic point discovered during driving by voice, the recorded voice can be reproduced and listened to later to be expressed by the recorded voice. The memories of the drive
You can recall with the location of the superb view point.
In particular, in this navigation device 1, the vehicle traveling history can be stored in the device by turning on the traveling route storage switch on the menu screen. If the voice memo function is stored in the storage unit 1, the voice memo function can be used instead of a travel log for a drive or a trip.

On the other hand, when using the navigation device 1 for business use, the vehicle occupant can easily create a business log using the voice memo function. That is, for example, when the navigation device 1 is used in a taxi service, the position where the customer is loaded, the position where the customer is lowered, and the like can be stored by voice, and information relating to the customer class such as the age of the customer. If you make a note of this by voice, detailed business management can be performed. Further, when the navigation device 1 is used for home delivery, collection and delivery, and the like, events that occur in the business process can be stored in the device without any omission by a simple operation.

In addition, the navigation device 1 of the present embodiment
Then, since the contents of the call of the mobile phone can be recorded, the vehicle occupant can recall the contents of the call if the recorded contents of the call are reproduced later. In this state, since the recorded contents must always be checked by the navigation device, the navigation device 1 of the present embodiment checks the recording position of the audio data stored in the above processing on the surrounding map, The history display process can be executed so that the data can be extracted to the outside.

Hereinafter, this history display processing executed by the control section 41 will be described in detail with reference to FIG. FIG. 6 is a flowchart showing the history display processing. This history display processing is performed by selecting a history of the day that the vehicle occupant wants to check from the daily history list displayed by touching the history display switch on the menu screen,
This is executed by the control unit 41.

When the processing is executed, first, the control unit 41
At 510, the history information of the day selected by the vehicle occupant is read. That is, in S510, the control unit 41 reads information such as the recording position and recording time of the audio data recorded in the RAM, and based on the information, in S520, reads the recording position of the audio data from the map data storage unit. Reads out map data in a displayable range and displays a map screen around the recording position. Then, the control unit 41 displays the voice mark 43 and the telephone mark 45 on the map screen in S530. At this time, the control unit 41 controls the voice mark 4
The recorded time is displayed in characters around 3 and the telephone mark 45, and the current location mark 42 is also displayed on the map screen if the current position of the vehicle is within a range that can be displayed on the map.

Further, in S540, the control unit 41 checks whether there is a travel history on the day selected by the vehicle occupant, and if there is a travel history (Yes in S540), the travel route is set along the road. On the map screen (S5
50) Then, the process proceeds to S560. If there is no traveling history (No in S540), the process in S550 is not performed and the process proceeds to S560.
At 560, a selection button 47a marked "Save" and a selection button 47b marked "Return" are displayed below the map screen. FIG. 7 shows S510 to S56.
FIG. 4 is an explanatory diagram illustrating a configuration of a screen displayed on a display unit 25 of the navigation device 1 when the steps up to 0 are completed.

Thereafter, the control section 41 proceeds to step S57.
0, it is determined whether or not the selection button 47a has been touched by the vehicle occupant. If the selection button 47a has been touched, these histories are transmitted from the vehicle occupant to a floppy disk (FD).
34, the data relating to the history is converted to HTML (HyperText Markup) in S580.
Language) format, and in S590, the converted data is stored in the FD3
Write to 4 and save.

That is, in S580, the control unit 41 converts the audio data of the day specified by the vehicle occupant at the start of the history display processing into the WAVE format or the MPEG (Moving Picture Exper
ts Group) MP compressed by the standard audio compression method
The audio data is converted into audio data reproducible by a personal computer represented by three types or the like, and the recording positions of these audio data are marked on an area map showing the traveling route of the vehicle on that day (audio mark 43, telephone mark) 4
The image data displayed as 5) is converted to GIF, TIFF,
The image data is converted into image data of a JPEG, BMP format or the like that can be displayed on a monitor of a personal computer.

Further, when the mark on the image data is selected by the mouse attached to the personal computer (ie, at the coordinate position representing the mark),
When a mouse click operation is performed), a program file from which audio data corresponding to the mark is reproduced is set to H
It is created in the TML format, and in S590, the converted audio data, image data and program file are stored on a floppy disk. Of course, when there is no traveling history of the day, the traveling route is not shown in the image data.

When the step at S590 is completed, the control unit 41 announces by voice at step S600, "Do you want to delete the driving history?" At 25, the same text is displayed, and selection buttons marked "Delete" and "Don't Delete" are displayed (not shown), and the vehicle occupant "Deletes".
When the control button 41 is touched, the control unit 41
Assuming that a command to delete the travel history has been issued (Yes in S600), the process proceeds to S610, and the corresponding travel history is deleted. On the other hand, in this S600, when the displayed selection button marked “do not delete” is touched by the vehicle occupant, control unit 41 does not delete the traveling history (S600).
(No in 600), the history display process ends. In the case where the traveling history is not stored, the control unit 41 does not notify the above-mentioned "Delete traveling history?"
It is determined as No at 00, and the history display process ends.

On the other hand, if the control unit 41 determines in step S570 that the selection button 47a has not been touched by the vehicle occupant, the control unit 41 shifts the processing to step S630, and the mark displayed on the screen (the voice mark 43, Phone mark 4
It is determined whether or not 5) has been selected (touched). If the mark has been selected (Yes in S630), in S640, the above-described reproduction process shown in FIG. It reproduces and outputs sound from the speaker 31a.

The control unit 41 determines whether a mark has not been selected in S630 (No in S630),
When the processing of S640 is completed, it is determined in S650 whether or not the selection button 47b has been touched by the vehicle occupant. If the selection button 47b has been touched, it is determined that a command to end the history display has been issued by the vehicle occupant, and the processing is performed. finish.

If control unit 41 determines that selection button 47b has not been touched (No in S650), it returns the process to S570 and repeats the above steps. Therefore, in the navigation device 1, the vehicle occupant causes the device to write the voice data stored using the voice memo function and the call recording function into the FD 34, and
If the data in D34 is read into a personal computer, the computer can easily manage audio data and the like.

That is, since not only audio data but also image data and an HTML format program file are written in the FD 34, the vehicle occupant can download software for displaying an HTML format file called a browser to a personal computer. If installed, the audio data can be played back or the recorded position can be confirmed on a map with the same feeling as the navigation device 1 by simply reading the data written in the FD 34 into the software. .

As a result, the vehicle occupant does not need to bother reproducing the voice and the like recorded by the navigation device 1, and can accumulate and manage these data every day. In addition, in addition to this, data representing the outside air temperature is periodically acquired from the outside air temperature sensor attached to the vehicle as the outside sensor group 21 of the navigation device 1, and
If the data is stored in the RAM of the control unit 41 together with the position information of the vehicle obtained from the position detection unit 10, the sound data can be recorded together with the information on the weather (outside temperature) on the day when the sound was recorded. It is possible.

While the configuration of the navigation apparatus 1 to which the present invention is applied and the processing in the control unit 41 have been described above, the control unit 41 of the information recording apparatus of the present invention uses the position detecting unit 10 The memory means stores the recording position (recording position) and the recording time by executing the above voice memo processing and call recording processing, This corresponds to the operation of saving data. Further, the communication means of the present invention corresponds to the mobile phone 35 connected to the navigation device in the present embodiment. The display unit corresponds to the display unit 25 in the present embodiment, and the display control unit controls the display unit 25 so that the user can visually recognize the map screen and the presence of the voice input. Marks 43 and 45 for
And the like are displayed on a map. Further, the time information acquisition means of the present invention is characterized in that the control unit 41 performs the voice memo processing,
When the call recording process is executed and the recording time is stored together with the recording position (S210, S310), this corresponds to an operation of acquiring the time from its own internal clock. The voice input unit corresponds to the voice input unit 29, and the notification unit corresponds to the voice output unit 31. Further, the notification control means includes a control unit 41.
Reproduces the recorded contents in the reproduction process,
1 corresponds to an operation of outputting sound.

Further, the information recording apparatus of the present invention is mainly adapted to record the voice of the user together with the recording position thereof, and is not limited to the above-described embodiment unless it violates the gist. Instead, various modes can be adopted. For example, in the navigation device 1 of the present embodiment, the audio data is stored in the memory (RAM) of the control unit 41. Instead, a hard disk drive is built in the navigation device, and the audio data is stored in the hard disk. It may be stored. Since the hard disk is less expensive than the memory (RAM), the storage capacity of voice data in the navigation device can be increased at low cost.

In the navigation device 1, the data can be written to a floppy disk (FD) 34 in order to retrieve the voice data and the like stored in the device to the outside. It is also possible to connect to the Internet or the like and transmit data to an external device via the communication network.

For example, when such processing is realized in the navigation device 1, after the vehicle occupant operates the mobile phone 35 to connect to the Internet, the control unit 4
1 converts the data (S580) converted into the HTML format into
The history display processing may be changed so that the history display processing is transmitted to the mobile phone 35 instead of the floppy disk.

In addition, when a plurality of voices (voice data) are stored, the control unit 41 displays the stored voice data list when a user inputs a voice data list display command from an external operation. Then, the user selects one of the listed audio data, and when the user selects the selected audio data, the selected audio data is reproduced from the audio output unit, and the recorded content (audio content) is transmitted to the user. ) May be configured to be notified. Further, the control unit may be configured to display only the marks 43 and 45 corresponding to the selected audio data on the map. If you do this,
It is possible to clearly display the recording position to the user.

When recording a call as shown in FIG. 4 (b), if the control unit determines in S330 that the call has ended, the control unit records the current position and the call end time at the end of the call. Then, in S360, the current time (that is, the call start time) recorded in S310 and the position at the start of the call, and the call end time and the call end position are marked on the screen with characters indicating the time, It may be displayed.

On the other hand, a camera may be mounted on the vehicle, the camera may be connected to a navigation device, and the image captured by the camera may be stored in the device together with the sound recording position and the recording time. This way, later,
It is possible to check not only the sound but also the image together with the recording position. Of course, in addition to this, a configuration may also be possible in which the control unit records only the image instead of the sound together with the recording position and the recording time. This is convenient because only the sound is replaced with an image, but an object that cannot be expressed by the sound (such as a landscape) can be recorded together with its position. In this case, the external device (camera)
If the navigation device is provided with a communication port for receiving image data from the camera and a camera is connected to this communication port, an image can be recorded in the same procedure as in FIG.

In addition to the above, the information recording apparatus has been described above.
Although the in-vehicle type navigation device has been described as an example, the information recording device of the present invention is not limited to this, and may be applied to a mobile terminal represented by a mobile phone or the like.
