Title: Device for vehicle, computer-readable medium for displaying information, and system for vehicle

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application is based on Japanese Patent Application No. 2012-106048 filed on May 7, 2012, and No. 2013-13489 filed on Jan. 28, 2013, the disclosures of which are incorporated herein by reference. 
     TECHNICAL FIELD 
     The present disclosure relates to a device for a vehicle and a system for a vehicle, which are capable of using information provided from an outside server and to a computer-readable medium for displaying information provided from an outside server. 
     BACKGROUND ART 
     An information distribution service to make information provided from a server connected to a network available is provided. In an application using map data, which is one of such an information distribution service, a terminal device and a portable communication terminal operate in cooperation, and a data volume to be transmitted is calculated on the portable communication terminal side to determine a display method of images and convert data while information is displayed on the terminal device side according to the data (for example, Patent Literature No. 1). 
     The information distribution service in recent years provides not only information for vehicles but also various types of information. Hence, instead of limiting an application as in Patent Literature No. 1, the vehicle device and the portable communication terminal are allowed to run a common application, so that the information distribution service becomes available also on the vehicle device side in the same manner as with the portable communication terminal. 
     However, in a typical information distribution service, an interface, for example, for the portable communication terminal is provided. Hence, when a common application is run, a screen same as a screen on the portable communication terminal is also displayed on the vehicle display side. In this case, displayed characters are small or a driver has to scroll the screen. Hence, the information distribution service has a problem that a screen displayed on the vehicle device is hard to see for the driver.

     EMBODIMENTS FOR CARRYING OUT INVENTION 
     Hereinafter, an embodiment of the present disclosure will be described with reference to  FIG. 1  through  FIG. 16 . 
     As is shown in  FIG. 1 , a vehicle system  1  includes a vehicle device  2  and a portable communication terminal  3 . The vehicle system  1  is connected to an intermediate server  5  via an outside network  4  connected to the portable communication terminal  3  so that the vehicle system  1  and the intermediate server  5  can communicate with each other. The vehicle system  1  is also connected to a content server  6  to enable communications therebetween. The vehicle system  1  is equipped to an unillustrated vehicle. In this case, the vehicle device  2  is not limited to a type provided fixedly, for example, in an interior of the vehicle and can also be of a type provided in a movable manner. 
     Firstly, a utility form of contents in the vehicle system  1  will be described briefly. The vehicle system  1  can use various contents provided by the content server  6 . Examples of available contents include but not limited to an information distribution service, a POI (Point Of Interest) search service, an SNS, and a music streaming service. These contents are provided by more than one content provider. In other words, for example, the SNS may be provided by a plurality of content providers, such as a provider AM, a provider BBB, and a provider CCC. 
     These contents are often provided in data formats determined by respective content providers. The vehicle system  1  is therefore connected to the intermediate server  5  that converts contents provided in various data formats from the respective content providers to a unified data format between the mobile terminal and the content server  6 . Of various services mentioned above, a subject of this embodiment is the information distribution service. 
     As is shown in  FIG. 2 , the vehicle device  2  has a vehicle-side control portion  10 , a vehicle-side display portion  11 , a vehicle-side operation input portion  12 , a vehicle-side sound input and output portion  13 , a vehicle information acquisition portion  14 , a vehicle-side storage portion  15 , a vehicle-side connection portion  16 , and a vehicle-side location detection portion  17 . The vehicle-side control portion  10  is formed of an unillustrated micro-computer having a CPU, a ROM, a RAM, and so on, and controls the entire vehicle device  2  according to programs stored in the ROM or the like. Also, the vehicle-side control portion  10  can run an application operating in cooperation with the portable communication terminal  3 . Hence, the vehicle-side control portion  10  can operate in cooperation with the portable communication terminal  3  and also becomes able to use contents provided from an outside server in a configuration common with the portable communication terminal  3 . 
     In this embodiment, processing itself to use the contents is performed by an application run on the portable communication terminal  3 . More specifically, the portable communication terminal  3  does not function merely as a communication device, but uses contents according to an instruction from the vehicle device  2 . The vehicle device  2  of this embodiment therefore functions as an operation terminal to operate the portable communication terminal  3 . The vehicle-side control portion  10  forms a control device and a vehicle-side control device. 
     The vehicle-side display portion  11  is formed, for example, of a liquid crystal display, an organic EL display, or a plasma display, each of which is capable of displaying colors. The vehicle-side display portion  11  displays, for example, an operation screen and an application running screen of the image display device  2  or a map screen when a navigation function is in use. The vehicle-side display portion  11  forms a display device and a vehicle-side display device. 
     The vehicle-side operation input portion  12  is formed of a touch panel provided correspondingly to the vehicle-side display portion  11  and contact switches arranged on a periphery of the vehicle-side display portion  11 . A user inputs an operation on the image display device  2  from these elements forming the vehicle-side operation input portion  12 . A touch panel of any type, for example, a touch panel of a pressure-sensitive type, an electromagnetic induction type, or an electrostatic induction type, can be adopted. The vehicle-side operation input portion  12  forms an operation input device. 
     The vehicle-side sound input and output portion  13  has unillustrated speaker and microphone. The vehicle-side sound input and output portion  13  outputs, for example, music stored in the vehicle-side storage portion  15  and a guiding voice from the image display device  2 . Also, a user&#39;s voice operation on the image display device  2  or the like is inputted into the vehicle-side sound input and output portion  13 . The vehicle-side sound input and output portion  13  forms a sound output device. 
     The vehicle information acquisition portion  14  connects to an ECU  7  or the like and acquires various types of information on the vehicle. In this embodiment, the vehicle information acquisition portion  14  acquires vehicle information capable of determining whether the vehicle is travelling or not, more specifically, a speed of the vehicle, from the ECU  7 . The vehicle information acquisition portion  14  forms a vehicle information acquisition device. The vehicle-side storage portion  15  stores therein music data, map data used for the navigation function, and various applications run on the vehicle device  2 . The vehicle-side storage portion  15  also stores therein the vehicle information. 
     The vehicle-side connection portion  16  makes communications with the portable communication terminal  3 . In this embodiment, a wireless communication system compatible with Bluetooth (registered trademark) is adopted. Hereinafter, Bluetooth (registered trademark) is abbreviated to BT and a connection by BT is referred to as the BT connection. The vehicle-side connection portion  16  has, for example, data communication profiles  16   a  (in the case of BT, corresponding to SPP and DUN), and connects to the portable communication terminal  3  using such profiles. The vehicle-side connection portion  16  forms a communication device. 
     The vehicle-side location detection portion  17  has so-called a GPS unit and a gyro sensor, and acquires an own location of the vehicle device  2 , more specifically, an own location of the vehicle provided with the vehicle device  2 . A method of acquiring an own location by the GPS unit or the like is known and a detailed description is omitted herein. The vehicle-side control portion  10  performs navigation processing to guide the vehicle to a destination according to an own location, that is, a location of the vehicle detected by the vehicle-side location detection portion  17 . 
     As is shown in  FIG. 3 , the portable communication terminal  3  has a terminal-side control portion  20 , a terminal-side display portion  21 , a terminal-side operation input portion  22 , a terminal-side sound input and output portion  23 , a communication portion  24 , a terminal-side storage portion  25 , and a terminal-side connection portion  26 . In this embodiment, the portable communication terminal  3  is assumed to be so-called a smartphone. The terminal-side control portion  20  is formed of an unillustrated micro-computer having a CPU, a ROM, a RAM, and so on, and controls the entire portable communication terminal  3  according to programs stored in the ROM or the like. Also, the terminal-side control portion  20  can run an application operating in cooperation with the vehicle device  2 . The terminal-side control portion  20  forms a terminal-side control device. 
     The terminal-side display portion  21  is formed, for example, of a liquid crystal display or an organic EL display, each of which is capable of displaying colors. The terminal-side display portion  21  displays, for example, phone book data, and images and videos stored, for example, in the terminal-side storage portion  25 . The terminal-side display portion  21  forms a terminal-side display device. The terminal-side operation input portion  22  is formed of a touch panel provided correspondingly to the terminal-side display portion  21  and contact switches arranged on a periphery of the terminal-side display portion  21 . An operation on the portable communication terminal  3  is inputted into the portable communication terminal  3  from these elements forming the terminal-side operation input portion  22 . A touch panel of any type, for example, a touch panel of a pressure-sensitive type, an electromagnetic induction type, or an electrostatic induction type, can be adopted. The terminal-side operation input portion  22  forms a terminal-side operation input device. 
     The terminal-side sound input and output portion  23  has unillustrated microphone and speaker, and uttered sounds are inputted therein and received sounds are outputted therefrom during a call. The terminal-side sound input and output portion  23  also outputs, for example, music and sounds of videos stored in the terminal-side storage portion  25 . The communication portion  24  performs a wide area communication by connecting to a public circuit-switched telephone network and the network  4 . The communication portion  24  makes a call and transmits data to and receives data from the network  4 . The terminal-side storage portion  25  stores therein phone book data and music as well as various applications run on the terminal-side devices and data saved by the user. 
     The terminal-side connection portion  26  makes communications with the vehicle device  2 . In this embodiment, a BT-compatible wireless communication system is adopted as described above and the portable communication terminal  3  connects to the vehicle device  2  by a BT connection. As with the vehicle device  2 , the terminal-side connection portion  26  has data communication profiles  27   a  (in this embodiment, SPP and DUN), and connects to the vehicle device  2  using such profiles. Profiles are not limited to data communication profiles and the terminal-side connection portion  26  may have, for example, a hands-free profile (HFP in the case of BT). 
     A function of the configuration as above will now be described. In a flowchart described in the following, the portable communication terminal  3  is denoted as SP (Smart Phone). 
     Firstly, a general flow of processing performed in the vehicle device  2  will be described with reference to  FIG. 4  through  FIG. 6 . As is depicted in  FIG. 4 , after a start (ACC of the vehicle is switched ON), the vehicle device  2  connects to the portable communication terminal  3  (SP) by a BT connection (A 1 ) and starts a service (A 2 ). To start a service at Step A 2  means to start running an application operating in cooperation with the portable communication terminal  3  so as to use a service (contents) provided from the content server  6  via the portable communication terminal  3 . When the portable communication terminal  3  connects to the vehicle device  2 , the portable communication terminal  3  restricts an input of an operation thereon by the user. More specifically, the portable communication terminal  3  restricts operations other than an operation to disconnect from the vehicle device  3 . Meanwhile, an operation by the user is accepted at the vehicle device  2 . In other words, the vehicle device  2  operates in cooperation with the portable communication terminal  3  by transmitting an operation by the user when the contents are used to the portable communication terminal  3  and also by displaying contents acquired at the portable communication terminal  3  on the vehicle device  2 . 
     In this instance, as is shown in  FIG. 5 , the vehicle device  2  displays on the vehicle-side display portion  11  a home screen, in which icons I1 through I8 corresponding to contents to be used (that is, services to be used) are displayed. The user selects a desired service (see  FIG. 1 ) by an operation to touch any one of the icons I1 through I8. In the case of  FIG. 5 , the icon I1 is provided correspondingly to a service A, the icon I2 to a service B, the icon I7 to a service C, and so on. 
     As is depicted in  FIG. 4 , the vehicle device  2  subsequently determines whether the selected service is available to the vehicle device  2  or not (A 3 ). More specifically, the vehicle device  2  determines at Step A 3  whether settings to use the service provided from the content service  6  are already made or not. For example, in order to use a service of the SNS, it is necessary to register account information of the SNS. Hence, when the service is not available, that is, when the initial settings are not finished yet (A 3 : NO), the vehicle device  2  displays, for example, an account registration guide screen (A 5 ). 
     As is depicted in  FIG. 4 , when the initial settings are already made and the selected service is available (A 3 : YES), the vehicle device  2  provides the service (A 4 ). The vehicle device  2  continues to provide the service until the user gives an instruction to end the service being provided (A 6 : NO). Meanwhile, the vehicle device  2  ends the processing when the user gives an end instruction (A 6 : YES). 
     In this manner, the vehicle device  2  can use the service selected by the user by operating in cooperation with the portable communication terminal  3 . 
     A description will now be given to an operation when using the information distribution service, which is the subject of the present disclosure, with reference to  FIG. 6  through  FIG. 16 . 
     The vehicle device  2  performs information display processing depicted in  FIG. 6 . For example, when an icon I7 corresponding to sports news distribution (in this embodiment, corresponding to service G) is operated, the vehicle device  2  performs a communication procedure to acquire contents (information on sports or the like) from the server (content server  6 ). In this instance, the vehicle device  2  performs a display procedure (B 1 ) to display a contest list screen displaying a list of the acquired contents as shown in  FIG. 7 . The contest list screen of  FIG. 7  is provided with title display portions M1 to display a plurality of news titles (or leads of the news), a scroll bar M2 to scroll the list, a flash news tab M3 to select flash news displaying news in a text format, and photo news tab M4 to select photo news displaying news with a photo (image). In  FIG. 7 , flash news is displayed and the flash news tab M3 is hatched to schematically indicate that the flash news is selected now. 
     The user can browse detailed information of the content, that is, a body text of the news by an operation to touch the title display portion M1 provided correspondingly to the news he wishes to check on the contest list screen, that is, by inputting a selection operation. 
     When the contest list screen is displayed, the vehicle device  2  acquires the vehicle information capable of specifying whether the vehicle is traveling by means of the vehicle information acquisition portion  14  (B 2 ) in the information display processing depicted in  FIG. 6 . The vehicle device  2  subsequently determines whether the vehicle is traveling or not on the basis of the vehicle information (B 3 ). Upon determining that the vehicle is not travelling (B 3 : NO), the vehicle device  2  proceeds to Step B 5 . On the contrary, upon determining that the vehicle is traveling (B 4 : YES), the vehicle device  2  performs traveling restriction processing (B 4 ). The traveling restriction processing will be described in detail below. 
     The vehicle device  2  subsequently performs content edit processing to reduce an information amount of the content (B 3 ). The content edit processing is the processing to reduce an information amount of detailed information contained in the acquired content, more specifically, an information amount to be displayed on the vehicle-side display portion  11  to be less than an information amount of the detailed information displayed on the terminal-side display portion  21  of the portable communication terminal  3 . In short, an information amount to be visually provided to the user is reduced in the vehicle device  2  of this embodiment. An information amount is reduced, for example, by methods (a) through (d) as follows. 
     (a) Display regions for respective types of detailed information contained in the acquired content and a character size displayed on each display region are set in advance and the display region is set as an upper limit of a display configuration. More specifically, for example, when a capacity of a given display region is set to two-line text data, text data exceeding two lines is not displayed therein. 
     (b) Of the detailed information contained in the acquired content, a type of detailed information to be displayed is set in advance, so that detailed information of the pre-set type is extracted and displayed. More specifically, when a title, a body text, an image (still image), a video (moving image), and the like are contained in the content, only the title and the image are displayed. 
     (c) When a plurality of pieces of information of the same type are contained in the detailed information contained in the acquired content, any one of these pieces of the detailed information is displayed. More specifically, for example, when a plurality of images are contacted in the content, only one of these images is displayed. 
     (d) Of the detailed information contained in the acquired content, a summary of information containing text data is extracted or created and the summary is displayed. More specifically, for example, when a summary is contained at the beginning of the body text or a summary portion is explicitly stated in the body text, the summary portion is extracted. Alternatively, a summary may be created by extracting keywords from the body text and connecting these keywords. When is it difficult to extract or create a summary, a list of keywords extracted from the body text may be used as an alternative to the summary. 
     When a selection operation is inputted by the user (when the vehicle device  2  performs an operation input procedure) after the content edit processing, the vehicle device  2  output the content (B 6 ). For example, when the content edit processing is performed by the method (d) above, the vehicle device  2  displays a summary screen as shown in  FIG. 8 . This summary screen displays a summary of the body text of the acquired content. 
     A summary extraction method will now be described concretely. 
     Contents acquired from the server can be text data written, for example, in an XML (Extensible Markup Language) as shown in  FIG. 17A  through  FIG. 17C . Although the XML is known and a detailed description is omitted herein, the XML is a language to write in which manner data appear, such as a paragraph construction of sentences (descriptive content of contents) and a size and a color of fonts, as text data together with the sentences. Hereinafter, data written in the XML is referred to as an XML file M20 for ease of description. It should be appreciated that  FIG. 17A  through  FIG. 17C  show examples written in the XML and sentences and writing formats are not limited to those shown in  FIG. 17A through 17C . 
     The XML file M20 contains a plurality of RSS fields M21(I) and M21 (II) placed between tags &lt;item&gt; and &lt;/item&gt;. Herein, RSS means an XML-based format to write metadata, such as a headline and a summary of a WEB site, by restructuring and is chiefly used to release update information of the WEB site. What referred to as RSS at this time include a plurality of formats, such as RDF Site Summary (RSS 0.9 and RSS 1.0), Rich Site Summary (RSS 0.91), and Really Simple Syndication (RSS 2.0). Although a writing method and usage of each RSS is different, these are referred to collectively as the RSS herein.  FIG. 17A  through  FIG. 17C  show examples written in RSS 2.0. 
     As is shown in  FIG. 18 , the RSS field  21  includes “title of news article”, “linked address of body text”, “linked address of image”, “briefing of article”, “date”, and so on. Of these items, “briefing of article” corresponds to the summary. That is, as will be described below, “briefing of article” in the RSS fields M21(I) and M21(II) is set in advance as the summary to be extracted in the vehicle device  2 . 
     Firstly, a configuration in which the portable communication terminal  3  alone acquires and displays contents thereon will be described by comparison. When the portable communication terminal  3  acquires contents as shown in FIG.  17 A through  FIG. 17C , the portable communication terminal  3  displays titles written in the RSS fields M21(I) and M21(II) of the XML file M20 in the title display portions M1 as shown in  FIG. 9A . When any one of the title display portions M1 is selected by the user, as is shown in  FIG. 9B , the portable communication terminal  3  displays a full text of the content (that is, details of an article) at an URL set as a link in the RSS fields M21(I) and M21(II). 
     When the portable communication terminal  3  uses a sports news distribution service alone as above, the portable communication terminal  3  can display the details of the contents entirely. However, because an information amount being displayed is large, the user may possibly fix his eyes on the portable communication terminal  3 . To eliminate such a risk, the vehicle device  2  reduces an information amount by displaying a summary of the content as will be described in the following. 
     When the vehicle device  2  acquires the contents as shown in  FIG. 17A  through  FIG. 17C , the vehicle device  2  displays the contest list screen shown in  FIG. 7  as described above. When any one of the title display portions M1 is selected by the user, the vehicle device  2  displays a summary of the article as shown in  FIG. 8 . The summary is portions placed between tags &lt;description&gt; and &lt;/description&gt; in the RSS fields M21(I) and M21(II). In other words, the vehicle device  2  extracts summaries of the respective contents using descriptions in the RSS fields M21(I) and M21(II). More specifically, the vehicle device  2  reduces an information amount by setting in advance a type of information to be displayed to the title and the summary in the RSS field  21  and extracting information of the pre-set type from the content and displaying the extracted information. 
     As has been described, the vehicle device  2  outputs (displays) the content in a display configuration different from that of the portable communication terminal  3  by extracting a summary of the content. In other words, when the vehicle device  2  displays detailed information contained in a content for which a selection operation was inputted, the vehicle device  2  performs the content edit processing to reduce an information amount of the detailed information to be less than an information amount of the detailed information displayed on the portable communication terminal  3 . The vehicle device  2  thus displays the content with an information amount reduced by the content edit processing. 
     Incidentally, when a summary is displayed, because an information amount is reduced as described above, the convenience is lowered more than necessary in some cases. To eliminate this drawback, the vehicle device  2  displays a read more button M5 on the summary screen. Although it is not shown in the drawing, when the user touches the read more button M5, the vehicle device  2  outputs the text data in a voice. Owing to this configuration, a screen easy to see for the user is provided on one hand and a possibility of lowering the convenience more than necessary is reduced on the other hand. 
     The traveling restriction mentioned above will now be described. The vehicle device  2  provides a screen easy to see for the user by performing the content edit processing to reduce an information amount. Nevertheless, the user may possibly take a look at the screen when the screen displays detailed information even when an information amount is reduced. To forestall such a risk, the vehicle device  2  is configured so as not to display detailed information at all as shown, for example, in  FIG. 10  by performing the traveling restriction while the vehicle is travelling. A risk that the user fixes his eyes on the screen can be thus lowered. Herein, when the vehicle device  2  performs the traveling restriction processing, an input itself of a selection operation by the user, for example, on the contest list screen shown in  FIG. 7  may be restricted. 
     In other words, the vehicle device  2  determines whether the vehicle is travelling or not on the basis of the vehicle information and restricts a display on the vehicle-side display portion  11  and/or an input to the vehicle-side operation input portion  12  upon determining that the vehicle is travelling. However, in order to prevent the convenience from being lowered more than necessary, for example, a voice button M6 may be provided so that an output in a voice is permitted even when the vehicle device  2  is performing the travelling restriction processing. 
     As has been described, the vehicle device  2  displays the acquired content in a state in which an information amount is reduced. 
     It should be noted that the vehicle device  2  is capable of displaying not only text data but also image data. For example, when the photo news tab M4 is operated on the contest list screen of  FIG. 7 , the vehicle device  2  displays a list of news with images as shown in  FIG. 11 . When any one item of news is selected by the user, the vehicle device  2  displays detailed information as shown in  FIG. 12 . In the case of  FIG. 12 , an image display portion M7, which is a region in which to display an image, is provided on a left side of the screen and a title display portion M8, which is a region in which to display a title, is provided on a right side of the screen. In other words, the vehicle device  2  sets a display region to display detailed information depending on a type of the detailed information (the method (b) above). In this case, the vehicle device  2  reduces an amount of information by displaying only the title instead of the body text. 
     On the contrary, when the portable communication terminal  3  uses contents alone by comparison, the portable communication terminal  3  displays a list screen as shown in  FIG. 13A . When any one item of news is selected by the user, the portable communication terminal  3  displays a detailed screen as shown in  FIG. 13B . The detailed screen of  FIG. 13B  contains, for example, ten pages of screen and photo images are contained in latter pages. In other words, contents acquired from the content server  6  contain more detailed information, such as the outcome of a game and overall records, as well as photo images. 
     By limiting types of information to be displayed and setting a display region in advance and displaying the information using the region as an upper limit, the vehicle device  2  reduces an information amount to be displayed in comparison with a case where the portable communication terminal  3  uses the content alone. 
     It should be also noted that the vehicle device  2  can use other contents in addition to sports information. For example, assume that the user touches an icon I3 corresponding to a photo search service (a service to store photographs appended with location information in the content server  6  and provide the stored photographs, which is capable of setting a destination according to the location information of a photograph) on the home screen shown in  FIG. 5 . Then, the vehicle device  2  performs the processing to acquire contents as described above and subsequently outputs the contents (B 6 ) in the information display processing depicted in  FIG. 6 . 
     In this instance, the vehicle device  2  displays a screen as shown in  FIG. 14B . By comparison, the portable communication terminal  3  displays thereon images as shown in  FIG. 14A . Screens in  FIG. 14A  and  FIG. 14B  are provided with thumbnail display portions M9 for images (thumbnails) and user display portions M10 in which to display names of users who posted the images. When images are appended with location information, a destination button M11 and a spot keep button M12 are also displayed. The destination button M11 is a button used to input an operation to set a facility or a location specified by an image as a destination in the navigation function. The spot keep button M12 is a button used to input an operation to save a facility or a location specified by an image as favorite information (register in Spot Keep). 
     In the information display processing depicted in  FIG. 6 , when the content contains the location information (B 7 : YES), the vehicle device  2  determines whether the destination button M11 is operated (B 8 ), whether the spot keep button M12 is operated (B 11 ) and whether an update or end operation is performed (B 13 ). When none of these operations is performed (B 8 : NO, B 11 : NO, and B 13 : OTHER), the vehicle device  2  stays on standby. 
     When any one of the images is selected in this instance, the vehicle device  2  displays detailed information shown in  FIG. 15B . Herein, only the destination button M11 and the spot keep button M12 are displayed on the vehicle device  2  whereas, as is shown in  FIG. 15A , a slide-show button M13, a theme button M14, and a keyword input button M15 are further displayed on the portable communication terminal  3 . The slide-show button M13 is a button to play or stop a slide show to successively switch images. Hence, when the slide show is being played, a list of the acquired images is displayed on the portable communication terminal  3  while the images are successively switched. 
     On the contrary, the slide-show button M13 is not displayed on the vehicle device  2  and only one image is displayed. In short, the vehicle device  2  reduces an information amount by the method (c) above. 
     The theme button M14 and the keyword input button M15 provided on the side of the portable communication terminal  3  are buttons to set a refinement condition according to which images are filtered in the content server  6 . By inputting a theme (pre-set keyword) or an arbitrary keyword, the user can filter a myriad of images stored in the content server  6  to those he wishes to view. The theme button M14 and the keyword button M15 are not shown in  FIG. 15B  on the vehicle device  2  running the common application because operations on these buttons are restricted by the traveling restriction processing. That is to say, the travelling restriction processing may restrict a display itself on the screen besides an input of an operation. 
     When the user operates the destination button M11 shown in  FIG. 14B  or  FIG. 15B , because the destination button M11 is operated (B 8 : YES) in the information display processing depicted in  FIG. 6 , the vehicle device  2  sets a destination according to the location information of the content (B 9 ) and displays a map screen as shown in  FIG. 16  (B 10 ). As is known, the map screen not only displays an own car mark M16 specifying a location of the vehicle and a destination mark M17, but also provides a guidance on a route to the destination. Also, when the spot keep button M12 is operated (B 11 : YES), the vehicle device  2  registers the image or a facility specified by the image into Spot Keep (B 12 ). 
     In this manner, the vehicle device  2  uses various types of information provided by the information distribution service. 
     According to the embodiment described above, advantages as follows can be obtained. 
     The vehicle device  2  can operate in cooperation with the portable communication terminal  3  and also run an application that makes contents provided from the outside content server  6  available in a configuration common with the portable communication terminal  3 . In this instance, the vehicle device  2  performs the content edit processing to reduce an information amount of detailed information contained in a content for which a selection operation was made by the user to be less than an information amount of the detailed information displayed on the portable communication terminal  3 . The vehicle device  2  thus displays the content with an information amount reduced by the content edit processing. Accordingly, an information amount displayed on the screen is reduced and a screen easy to see for the user can be provided by the vehicle device  2 , too. Hence, the convenience when the information distribution service is used in the vehicle can be enhanced. 
     By performing the content edit processing using the methods (a) through (d) above, the vehicle device  2  can reduce an information amount for various contents and depending on types of detailed information contained in the contents. 
     When the read more button M5 or the voice button M6 is operated by the user, the vehicle device  2  outputs the text data in the detailed information contained in the acquired content in a voice. Hence, the vehicle device  2  can prevent the convenience from being lowered more than necessary while providing a screen easy to see for the user. 
     The vehicle device  2  determines whether the vehicle is traveling or not on the basis of the vehicle information, and upon determining that the vehicle is traveling, performs the traveling restriction processing to restrict an operation on respective buttons or a display itself on the vehicle device  2 . Owing to this configuration, a risk that the user fixes his eyes onto a screen can be lowered. 
     Also, an input of an operation to the portable communication terminal  3  is restricted while the portable communication terminal  3  is connected to the vehicle device  2 . Hence, an operation on the portable communication terminal  3  while the vehicle is travelling can be prevented. Safety while the vehicle is traveling can be thus enhanced. 
     By running the information display program to perform the control as above on the vehicle device  2  and according to the vehicle system  1  using the vehicle device  2 , safety when the information distribution service is used in the vehicle can be enhanced as has been described above.
