The navigation device 1 determines a map display range, a route search start point, and the like based on the current location of the vehicle detected by the current location detection device 14, and displays the current location on the map.

  The image memory 15 stores image data to be displayed on the display monitor 16. The image data includes road map drawing data and various graphic data, which are appropriately generated in the control circuit 11 based on the map data stored in the DVD-ROM 112.

The DVD-ROM 112 stores facility data. Facility data is data relating to facilities (POI) classified by genre such as gas stations and restaurants. The facility data includes location data indicating the location of the facility, facility address data, telephone data, and the like. The facilities are categorized into any genre and tabulated, and displayed on the map with icons for each genre. When the icon display mode in which the facility icons are always displayed is selected, the facility icons of a predetermined genre are displayed on the map screen.
As will be described in detail below, in the destination setting mode, the facility is set as the destination by pressing the facility icon on the screen according to the facility search result.

  The disk drive 111 reads map data from the DVD-ROM 112. The map data includes map display data, route search data, and the like. The map display data and the route search data include road link information and node information stored in the map data. The map display data has map data of a plurality of scales from wide areas to details, and the scale of the display map can be changed according to a user request. The map data may be read from a recording medium other than the DVD-ROM 112, such as a CD-ROM or a hard disk.

  The display monitor 16 displays various information such as a map near the vehicle position based on various information such as map data. The speaker 17 outputs sound for instructing the user to perform various input operations and for guiding the route. The input device 18 has operation keys for the user to set various commands and input search conditions, and is realized by a button switch on the operation panel, a hard switch around the panel, or the like.

Then, the processes defined in the various touched buttons and the display menu are executed.

  When the destination is set by the user, the navigation device 1 performs a route calculation from the current location detected by the current location detection device 14 to the destination based on a predetermined algorithm. The route thus obtained (hereinafter referred to as a recommended route) is displayed on the screen in a manner different from other roads by changing the display form, for example, the display color. Thereby, the user can recognize the recommended route on the map on the screen. Further, the navigation device 1 instructs the user in the direction of travel using a screen or voice so that the vehicle can travel according to the recommended route, thereby guiding the route of the vehicle.

  The microphone 113 inputs a voice uttered by the user. The voice recognition unit 114 recognizes the meaning of the voice represented by collating the voice pattern of the voice input from the microphone 113 with the voice pattern stored in the dictionary 115. The recognition result is output to the control circuit 11. The microphone 113 is provided with a voice recognition button (not shown). When the voice recognition button is turned on, the voice recognition unit 114 performs voice recognition on the input voice.

  In addition, the voice recognition unit 114 can identify a speaker from among registered users. As a registration method, for example, a predetermined word meaning (speaker specific word meaning) for specifying a speaker is made to speak to a plurality of users toward the microphone 113, and the voice recognition unit 114 is characterized by the voices of each user. A point is extracted and registered as a table in which a user is associated with a feature point of the voice pattern. When the user utters the speaker specific meaning toward the microphone 113, the voice recognition unit 114 extracts the feature point of the voice input to the microphone 113, and specifies the speaker by referring to the table.

  Next, the function execution process of the navigation device in the embodiment of the present invention will be described with reference to the flowchart of FIG. The processing in FIG. 2 is executed in the control circuit 11 by a program that starts when a voice recognition button (not shown) provided in the microphone 113 is turned on.

  In step S101, it is determined whether or not sound is input to the microphone 113. If a voice is input, an affirmative determination is made in step S101, and the process proceeds to step S102. If no voice is input, step S101 is repeated. In step S102, the timer 11a is started. In step S103, based on the touched position of the touch panel 19 calculated by the touch panel control unit 110, it is determined whether or not a touch operation has been performed on the touch panel. If there is a touch operation, an affirmative decision is made in step S103, and the process proceeds to step S104. If there is no touch operation, a negative determination is made in step S103, and the process proceeds to step S106.

  In step S104, voice recognition & touch operation mode processing is executed. Details of the voice recognition & touch operation mode processing will be described later. In step S105, it is determined whether or not a voice recognition button (not shown) provided on the microphone 113 is turned off. When the voice recognition button is turned off, an affirmative determination is made in step S105, and the function execution process of the navigation device is terminated. If the voice recognition button is on, a negative determination is made in step S105, and the process returns to step S101.

  In step S106, it is determined whether or not a predetermined time has elapsed since the timer 11a was started. If the predetermined time has elapsed, an affirmative determination is made in step S106, and the process proceeds to step S107. If the predetermined time has not yet elapsed, a negative determination is made in step S106, and the process returns to step S103. In step S107, normal speech recognition mode processing is executed. The normal voice recognition mode process is a mode in which the voice input from the microphone 113 is recognized and the process is executed based on the recognition result. Normal speech recognition mode processing is not different from normal speech recognition processing, so description of normal speech recognition mode processing will be omitted. For example, regardless of the user, processing based on the result of recognizing the input speech content is performed. It is. Then, the process proceeds to step S105.

  Next, with reference to FIG. 3, the voice recognition & touch operation mode process in step S104 of FIG. 2 will be described.

  In step S201, the voice input from the microphone 113 is analyzed. In step S202, the speech recognition unit 114 is made to recognize the utterance content. In step S203, the voice recognition unit 114 is caused to execute a process for specifying a user.

  In step S204, based on the touch position of the touch panel 19 calculated by the touch panel control unit 110, it is recognized what touch operation has been performed. In step S205, processing to be executed by the navigation device 1 is determined based on the utterance content (meaning) recognized in step S202, the user specified in step S203, and the touch operation recognized in step S204. In step S206, the navigation apparatus 1 is caused to execute the process determined in step S205.

  For example, as shown in FIG. 4, when user A speaks “destination”, the destination is set at the touched position, and when user B speaks “destination”, the touched position is centered. As a default, registration is performed so that the peripheral facility search of the leisure facility is performed. In addition, when user A speaks “restaurant”, the facility search of the Chinese restaurant is performed within the range specified by the touch operation, and when user B speaks “restaurant”, Japan is searched within the range specified by the touch operation. Register by default to search for restaurant facilities.

  Then, when the user A speaks “Destination” and touches the map 20 displayed on the display monitor 16, the destination is set at the touched position 21 as shown in FIG. On the other hand, when the user B speaks “destination” and touches the map 20 displayed on the display monitor 16, as shown in FIG. And the searched facility icons 22 a to 22 c are displayed on the map 20. When the user touches any of the icons 22a to 22c, the facility of the touched icon is set as the destination.

  Further, when the user A speaks “restaurant” and draws the rectangular shape 23 on the map 20 displayed on the display monitor 16 by a touch operation, as shown in FIG. A restaurant is searched, and icons 24 a to 24 c of the searched facilities are displayed on the map 20. On the other hand, when the user B speaks “restaurant” and draws the rectangular shape 23 on the map 20 displayed on the display monitor 16 by touch operation, as shown in FIG. The restaurant is searched, and icons 25a to 25c of the searched facilities are displayed on the map 20. When the facility icon button is pressed, the destination setting process is executed.

The navigation device 1 according to the above embodiment has the following operational effects.
(1) When the voice is input from the microphone 113, the navigation device 1 identifies the user who is the speaker from the voice and recognizes the meaning of the voice. Further, the user's touch operation on the touch panel 19 provided on the display screen of the display monitor 16 is recognized. And the process regarding the function of the navigation apparatus 1 was performed based on the identified user, the recognized word meaning, and the recognized touch operation. Thereby, the navigation apparatus 1 can perform an appropriate process for every user.

(2) The navigation apparatus 1 identifies the user A, recognizes the word meaning of the destination, and sets the destination at the touch position 21 when the touch of one point is recognized. On the other hand, when the user B is identified, the word meaning of the destination is recognized, and a touch of one point is recognized, the vicinity of the leisure facility is searched with the touch position 21 as the center. As a result, even for user A who often designates a point on the map and sets a destination, and for user B who often sets a destination after searching for facilities around the leisure facility Appropriate processing can be executed.

(3) Moreover, the navigation apparatus 1 can perform the facility search within the range 23 designated by the touch operation based on the meaning of the word recognized by the voice recognition unit 114. In this case, even if the word meaning (for example, “restaurant”) recognized by the voice recognition unit 114 is the same, the genre of the facility (Chinese Chinese) to be searched when the user A is specified and when the user B is specified. The restaurant (Japanese restaurant) was changed. Thereby, appropriate processing can be executed for both user A who likes Chinese cuisine and user B who likes Japanese cuisine.

(4) The voice recognition unit 114 identifies the user based on one voice uttered by the user regarding the navigation function, and recognizes the meaning of the spoken word. Thereby, it is not necessary to separately provide a device for identifying the user in addition to the device for recognizing the voice.

The navigation apparatus 1 of the above embodiment can be modified as follows.
(1) As described above, the navigation device 1 identifies the user A, recognizes the word meaning of the destination, and identifies the user B while setting the destination at the touch position when the touch of one point is recognized. When the word “destination” is recognized and a touch of one point is recognized, the vicinity of the leisure facility is searched around the touch position. At this time, the word meaning recognized by the voice recognition unit 114 is not limited to the “destination” as long as the word meaning is related to the destination. For example, words such as “destination”, “arrival place”, and “destination place” can be used.

(2) As described above, the navigation device 1 searches for a Chinese restaurant when the user A is specified even when the word recognition recognized by the voice recognition unit 114 is the same, and the user B specifies When it is done, the genre of the facility to be searched is changed by searching for Japanese restaurants. Thus, the combination of the recognized word meaning and the genre of the search facility to be changed for each user is not limited to the Chinese restaurant and the Japanese restaurant for “restaurant”. For example, a different type of convenience store may be searched for each user with respect to the word “convenience store”, or a different type of gas station may be searched for each user with respect to the word “gas station”. In addition, the number of genres of search facilities to be changed for each user for one word meaning is not limited to two, and may be three or more. For example, when a user C different from the users A and B is specified for the word “restaurant”, an Italian restaurant may be searched.

(3) When a facility search within the range specified by the recognized touch operation is performed, the meaning recognized by the voice recognition unit 114 may be a meaning of a genre of a higher concept of the genre of the facility to be searched. For example, in the case of the first user, the elementary school is searched, and in the case of the second user, when the junior high school is searched, when the meaning of “school” which is the meaning of the upper concept of the elementary school and the junior high school is recognized, A search may be performed.

(4) The presence / absence of a touch operation is determined after voice input, and based on the determination result, processing based on the voice recognition result and touch operation (voice recognition & touch operation mode processing), and processing based only on voice recognition (normal voice recognition) (Mode processing) was used properly. However, only one of the processes may be validated in advance on the menu screen.

(5) In the present embodiment, the touch operation is performed after the voice input, but conversely, the touch operation may be performed first and then the voice input may be performed. That is, when a user's touch operation for designating a single point or a predetermined range is recognized, the speech recognition unit 114 recognizes the meaning of the voice input by the microphone 113 and the recognized touch operation and Based on the word meaning, the processing as described above may be performed.

(6) A menu screen for specifying the user may be provided so that the user can be specified from the menu screen. For example, a list of user names may be displayed on the display monitor, and the user may select the user name from the displayed user names so that the navigation device can identify the user.

(7) In the present embodiment, the user designates one point or a predetermined area on the map by a touch operation, but this may be performed by a so-called hard button operation. That is, the navigation device 1 has operation keys (hard buttons) realized by various button switches and hard switches in the input device 18 as described above. Instead of the touch operation, the user performs a hard button operation using this operation key so that the above-mentioned one point or a predetermined area can be designated on the map. For example, by moving the cursor on the map by operating the cross key and selecting a point corresponding to the position of the cursor by pressing the enter button, the user can select a desired point or a predetermined area on the map. Allow specification. In addition, you may provide the operation key for performing such hard button operation in the remote control etc. which were attached to the navigation apparatus 1. FIG. Further, a touch operation and a hard button operation may be performed in combination.

(8) The navigation device may be able to identify the user by using a mobile terminal device such as a mobile phone possessed by the user.

  It is also possible to combine one or a plurality of embodiments and modifications. It is possible to combine the modified examples in any way.

  The above description is merely an example, and the present invention is not limited to the above embodiment.
