Description

  The present invention relates to an information extraction apparatus, and more particularly to an information extraction apparatus that can easily extract desired information by selecting two types of options.

  Today, many information terminals such as ticket vending machines, mobile phones, and car navigation systems are installed and used. In these information terminals, it is possible to use many functions provided by the information terminal by selecting selection items displayed on the display panel. Nowadays, in addition to increasing the recording capacity of information terminals and increasing the speed of CPUs, etc., a variety of services that users use using information terminals have advanced, and many functions can be realized with one information terminal. It is possible.

  For example, in a general car navigation system, a map display process of the current position, a display scale change process of the map display, a destination change process, a guide route (hereinafter referred to as a route) change process, a route cancellation process, etc. Play / stop processing of music data (for example, MP3 data, etc.), viewing / stop processing of 1Seg and digital TV, playback / stop processing of DVD and Blu-ray Disc (registered trademark), and resort search process Various processes can be performed.

  As described above, when a large number of functions can be realized with one information terminal (for example, a car navigation system), the operation method for realizing the functions becomes difficult to understand as the functions increase. was there. In general, since all the operation methods are described in a manual, when a user performs an operation, it is possible to search for a desired operation method by referring to the manual. However, when a function name associated with a desired operation item is not known, it is difficult to obtain a target operation item even by referring to the manual.

  In addition, all the operation methods are organized into hierarchies based on the types of functions that can be realized by the operation methods, and a desired operation method is selected from the hierarchized functions based on the types and contents of target functions. A method for obtaining the value has also been proposed.

  However, in this way of organizing operation methods by hierarchizing by function, operation methods that are frequently used and those that are less frequently used are selected through the same operation procedure and operation burden (select the same number of times). There is a problem that it may be necessary to perform processing).

  On the other hand, a method has also been proposed in which only frequently used operations are displayed as icons, and the frequently used processes are quickly executed by selecting these icons. However, in today's car navigation system having a large number of functions, even if an operation method that is frequently used is assigned to an icon, the number of icons that can be displayed is limited, so it is difficult to assign an icon. ing.

  For this reason, the functions realized by the operation method are classified by general colloquial expressions, and further, this colloquial expression is a combination of a predefined noun, a predefined verb, and a predefined particle. There is proposed a method for specifying a target operation method by alternatively selecting a noun, a particle and a verb that have been decomposed by (see, for example, Patent Document 1).

  According to this specifying method, by providing an option for a particle, there is an advantage that a noun can be a subject of a verb or a noun can be a verb object. In this way, by selecting a noun, a particle, and a verb alternatively, it is possible to identify the best operation method for realizing a target function from among a large number of operation methods. It becomes possible. In particular, by using particles, it is possible to specify whether the noun is the subject or the object, so that the processing content can be determined in more detail, and one or more of the many operation methods can be determined. It is possible to obtain (extract) about two optimum operation methods.

JP 2008-46758 A

  However, in Patent Document 1, a plurality of options indicating a noun, a plurality of options indicating a particle, and a plurality of options indicating a verb are displayed on the display. For this reason, in order to specify the operation method, at least three types of icons (options) must be selected alternatively. When there are three types of items to be selected in this way, the selection burden tends to increase.

  In addition, by selectively selecting three types of icons, a noun icon, a particle icon, and a verb icon, as described above, the optimum operation method can be greatly narrowed down from a large number of operation methods. However, there has been a problem that a desired operation method may not be included in the extracted operation method list due to the substantial narrowing down.

  It is sufficient that the desired operation method is included in the narrowed down operation method, but if the desired operation method is not included in the narrowed operation method, the combination of nouns, verbs and particles is reconsidered. Therefore, the operation method extraction process must be performed from the beginning. Such re-extraction processing of the operation method causes an increase in the operation burden on the user, and there is a problem that it becomes difficult to find a desired operation method each time the operation is repeated.

  In particular, since the operation of the car navigation system is often performed before starting the vehicle or when the vehicle is stopped (for example, when waiting for a signal), the operation procedure is reduced so that the operation process of the car navigation system can be performed safely and smoothly. Therefore, it is desired to find an optimal operation method.

  The present invention has been made in view of the above problems, and reduces the burden of selecting an option and makes it easy for a user to provide information by narrowing the information narrowed down according to the option to some extent. It is an object of the present invention to provide an information extraction device that can be found.

  In order to solve the above-described problem, an information extraction apparatus according to the present invention includes two types of options including a plurality of target options including words that can be objects and a plurality of action options including words that can specify an action. An option display unit capable of displaying an option group on a display monitor in a state where none of the options constituting the two types of option groups is selected, and two types of option groups displayed on the option display unit A selection operation means capable of allowing a user to select any one of the plurality of target options and one of the plurality of action options; Information recording means for recording information defined based on the combination of the option and the action option according to the combination of the target option and the action option Information extracting means for extracting, from the information recording means, information defined based on the combination according to the combination of the one target option selected by the selection operation means and the one action option; And an information display means for displaying the information extracted by the information extraction means on the display monitor.

  In the information extraction apparatus according to the present invention, information defined based on the combination can be extracted from the information recording unit according to the combination of one target option and one action option selected by the selection operation unit. it can.

  For this reason, a user who needs information recognizes the information defined based on the combination by recognizing the content of the information in association with a combination of a word that can be an object and a word that can specify an action. Information can be extracted according to a combination of two options, and information search / extraction can be performed easily and intuitively.

  In particular, Japanese tends to be composed of a noun that can be an object and a verb that can specify an action on the object. A noun can correspond to a word that can be an object, and a verb can correspond to a word that can specify an action. Therefore, it is possible to give meaning to a combination of a word that can be an object and a word that can specify an action, and it is easy to associate information by considering the meaning based on this combination.

  For this reason, as compared with the case of associating information based on a simple character string, information can be easily associated, and information based on the association can be made difficult to forget.

  In the information extraction apparatus described above, the information defined based on the combination of the target option and the action option is at least one item of information, and the information extracted by the information extraction unit includes a plurality of information. In the case of items, the information extraction unit may extract all of the plurality of items, and the information display unit may display the extracted items in a list on the display monitor.

  As described above, according to the information extracting apparatus of the present invention, the information defined based on the combination of options is not necessarily limited to one item, and can be configured by a plurality of items. When information is configured by a plurality of items in this way, it is possible to give a wide range to information extracted by the purpose option and the action option. Even in the extraction process, it is possible to perform the information extraction process so that the information of the target item can be included in a plurality of extracted item results.

  Furthermore, according to the information extraction apparatus of the present invention, when there are a plurality of extracted information items, the information items can be displayed in a list, so that a desired item can be selected from the plurality of items. Can be easily determined and selected.

  Further, in the information extraction apparatus described above, the item of information recorded in the information recording unit is based on a combination of other options in which at least one of the combinations of the target option and the action option is different. Even if it exists, what may be provided with a common item may be sufficient.

  According to the information extraction apparatus according to the present invention, it is possible to include items common to the information included in the extraction result even if the combinations are different options. For this reason, it is difficult to select one option from a group of options, and even if one of the options is selected without hesitation, the target item can be included in the extracted information. Is possible. For this reason, the user can extract the information of the target item even if the option is selected intuitively or sensuously without strictly limiting the option.

  Further, the information extraction apparatus described above, when only one of the target option or the action option is selected by the selection operation unit, the option display unit includes an option group of the selected option and Is an option of a different option group, and information based on a combination with the selected option is changed to a display different from the other options in the display corresponding to the option not recorded in the information recording means. It may be displayed on the display monitor.

  As described above, in the information extraction device according to the present invention, when only one option is selected from the target option or the action option, it is an option of an option group different from the option group of the selected option, Information based on the combination with the selected option can be displayed on the display monitor by changing the display of the option corresponding to the option not recorded in the information recording unit to a display different from the other options.

  For this reason, an option for which information based on the combination with the selected option is not recorded, that is, an option for which information based on the combination with the selected option is not specified is changed to an option different from the other options. By displaying on the display monitor, the user can visually recognize the options related to the combination for which information is not specified, and effectively suppresses the user from selecting these options by mistake. Is possible.

  Further, in the information extraction apparatus described above, the selection of the option by the selection operation means may be to select the action option after selecting the target option, or to select the target option after selecting the action option. May also be possible.

  As described above, according to the information extraction device of the present invention, it is possible to select the action option after selecting the action option, or to select the action option after selecting the action option. It becomes possible to increase the degree of freedom of operation.

  In the information extraction apparatus described above, the information defined based on the combination of the target option and the action option is based on the content of a sentence configured with the target option as a target and the action option as a verb. It may be operation information for realizing a function that can be specified.

  As described above, according to the information extraction device of the present invention, the information defined based on the combination of the target option and the action option becomes the content of the sentence composed of the target option as the object and the action option as the verb. Since the operation information is for realizing a function that can be specified based on the information, the target operation information can be recognized in association with the content of the sentence. For this reason, even if the combination of options for extracting operation information is not strictly stored, it is possible to intuitively determine the optimum target option and action option by documenting the function to be realized. It becomes possible. Therefore, it is possible to intuitively specify selection items of options based on functions, and it is easy to realize speeding up and facilitating operation.

  Furthermore, in the information extraction device described above, the function that can be specified based on the content of a sentence configured with the target option as a target word and the action option as a verb is a function of a car navigation system, and realizes the function. The operation information for performing may be operation information for realizing the function of the car navigation system.

  According to the information extraction device of the present invention, a function that can be specified based on the content of a sentence that includes a target option as a target word and an action option as a verb is a function of the car navigation system, and realizes the function. Because the operation information for this is operation information for realizing the functions of the car navigation system, it is possible to quickly and easily extract the operation information necessary for the operation of the car navigation system simply by selecting two types of options. It becomes.

  In particular, in today's car navigation systems, there are a wide variety of functions that can be realized, and it is difficult to learn all the operation methods for realizing the functions. For this reason, operation information for realizing a target function can be obtained only by selecting two types of options, so that operation information can be searched quickly and easily.

  Furthermore, in the information extraction device according to the present invention, since the choice is composed of two types of choice groups of a word that can be an object and a word that can specify an action, a word that can specify an object and an action Since it is easy to associate functions that can be realized by a sentence composed of a combination of and an option, an option can be selected intuitively.

  According to the information extraction device of the present invention, information defined based on the combination is extracted from the information recording unit according to the combination of one target option and one action option selected by the selection operation unit. be able to.

  For this reason, a user who needs information recognizes the information defined based on the combination by recognizing the content of the information in association with a combination of a word that can be an object and a word that can specify an action. Information can be extracted according to a combination of two options, and information search / extraction can be performed easily and intuitively.

  In particular, Japanese tends to be composed of a noun that can be an object and a verb that can specify an action on the object. A noun can correspond to a word that can be an object, and a verb can correspond to a word that can specify an action. Therefore, it is possible to give meaning to a combination of a word that can be an object and a word that can specify an action, and it is easy to associate information by considering the meaning based on this combination.

  For this reason, as compared with the case of associating information based on a simple character string, information can be easily associated, and information based on the association can be made difficult to forget.

  Hereinafter, a car navigation device (hereinafter referred to as a navigation device) which is an example of an information extraction device according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a navigation device 1 according to an embodiment of the present invention. As shown in FIG. 1, the navigation device 1 includes a current position detection unit 10, a VICS (registered trademark) information reception unit 11, an input operation unit 12, an image memory unit (option display unit, information display unit) 13, A display monitor 14, a touch panel unit (selection operation unit) 15, a map data recording unit (information recording unit) 16, a speaker 17, a control unit (option display unit, information extraction unit, information display unit) 18, A RAM (Random Access Memory) 19 and a ROM (Read Only Memory) 20 are included.

  The current position detection unit 10 has a role of detecting the current position of the vehicle on which the navigation device 1 is mounted. The current position detection unit 10 includes a vibration gyro 10a, a vehicle speed sensor 10b, and a GPS (Global Positioning System) sensor 10c. The vibrating gyroscope 10a has a function of detecting the traveling direction of the vehicle (direction in the traveling direction). The vehicle speed sensor 10b has a role of detecting the vehicle speed by detecting a pulse emitted according to the travel distance of the vehicle from a pulse generator installed in the vehicle. The GPS sensor 10c has a role of detecting a GPS signal from a GPS satellite, and the control unit 18 uses the received GPS signal to determine the current position of the vehicle based on the coordinate position (for example, latitude based on the world geodetic system (WGS84)). It is possible to detect based on (longitude information).

  The VICS information receiving unit 11 has a role of receiving VICS information. The VICS information is information supplied by a VICS information center (not shown), and is information indicating road conditions such as the latest traffic jam information. The VICS information is transmitted mainly by a radio beacon installed on a highway or an optical beacon installed mainly on a general road. For this reason, the vehicle provided with the VICS information receiving unit 11 can reliably receive the VICS information by the VICS information receiving unit 11 by passing the vicinity of the installation position of the radio wave beacon and the optical beacon. .

  On the other hand, the VICS information may be transmitted by FM multiplex broadcasting. By transmitting VICS information by FM multiplex broadcasting, it is possible to transmit VICS information to a wider area than a radio wave beacon or an optical beacon. The VICS information receiving unit 11 can reliably acquire traffic information in a wide area by receiving VICS information transmitted by FM multiplex broadcasting in addition to VICS information transmitted by radio wave beacons and optical beacons. It has become. The VICS information received by the VICS information receiving unit 11 is output to the control unit 18.

  The input operation unit 12 is used when performing various operations in the navigation device 1 by an operation method other than the touch operation by the touch panel unit 15. Specifically, in addition to physical switches and buttons (for example, the tone adjustment switch 22 shown in FIG. 2) provided on the casing of the navigation device 1, a remote controller or the like corresponds to the input operation unit 12.

  The image memory unit 13 has a role of temporarily storing image data to be displayed on the display monitor 14. The image data is extracted from the map data recording unit 16 based on the current position information of the vehicle acquired by the control unit 18 from the current position detection unit 10 and the destination information set by the user. It is generated appropriately by combining various image information. In the control unit 18, the generated image data is recorded in the image memory unit 13, and the image data recorded in the image memory unit 13 is sequentially displayed as a map display or the like on the display monitor 14 of the navigation device 1. .

  The display monitor 14 has a role of displaying various information such as a road map near the vehicle position on the screen based on various information such as map data. For example, a liquid crystal monitor or a CRT monitor can be specifically used as the display monitor 14. The display monitor 14 can display operation menus and the like in the navigation device 1 using icons. The display contents of the operation menu using this icon and the processing contents thereof will be described in detail later.

  The touch panel unit 15 determines whether or not the user has touched the surface of the display monitor 14 with a finger, and when touched, has a role of determining input processing by the user based on the touch position. . The touch panel unit 15 includes a touch detection unit 15a and a touch control unit 15b.

  The touch detection unit 15a includes a transparent touch switch that is stacked on the surface of the display monitor 14. The touch detection unit 15a is a detection unit different from a physical switch such as the input operation unit 12, and the presence or absence of a touch operation on the display screen of the display monitor 14 is changed to a detection method such as an electrostatic method or a pressure sensitive method. Detect based on. Since the touch detection unit 15a includes a transparent touch switch or the like, the user can visually recognize an image displayed on the display monitor 14 via the touch detection unit 15a, for example, an image such as an icon described later. It has become.

  The touch control unit 15 b is interposed between the touch detection unit 15 a and the control unit 18. The touch control unit 15 b calculates a touch position on the touch panel unit 15 based on a signal detected by the touch detection unit 15 a (signal by a touch operation), and outputs the calculated touch position to the control unit 18.

  The map data recording unit 16 is configured by a general auxiliary storage device capable of recording map data, such as a hard disk, SSD, DVD-ROM, CD-ROM, and SD card. 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. . As map display data, map data of a plurality of scales from wide areas to details are prepared. By using this map display data, it is possible to change the scale of the display map according to the user's request. It has become.

  Further, the map data recording unit 16 records information related to a list of operation items displayed on the display monitor 14 in accordance with an icon selection operation described below. Specifically, information such as operation items defined based on a combination of icons belonging to the two types of frames described below is recorded in a database in advance according to the combination of icons. The map data recording unit 16 can output corresponding operation items as a list in accordance with an instruction from the control unit 18.

  The speaker 17 has a role of outputting a voice guidance guide for performing route guidance during navigation or outputting a voice guidance guide accompanying various input operations in the navigation device 1 to the user. .

  The control unit 18 has a role of performing various processes in the navigation device 1 such as a route search to a destination set by the user, an image generation process based on the searched route, and a guidance voice output process. The control part 18 is comprised by CPU (Central Processing Unit), for example.

  The RAM 19 serves as a work area for the control unit 18. For example, as will be described later, when the control unit 18 performs a process of displaying a list of operation items, the RAM 19 determines which of the plurality of icons displayed on the display monitor 14 is touched by the user. It is used to record data for making such judgments. The control unit 18 determines the touch operation state of the icon based on data recorded in a predetermined area of the RAM 19 (a set state of a specific flag (a specific bit is 0 or 1)).

  The ROM 20 stores various programs executed by the control unit 18. The control unit 18 can perform various control processes by reading a program from the ROM 20 and executing the program. For example, the ROM 20 stores a program as shown in FIG.

  In the control unit 18 according to the present embodiment, various programs are read from the ROM 20 and executed, thereby executing the road guidance processing in the navigation device 1 and accompanying the road guidance processing to be executed, a guidance route (guidance route) : Map information used for (route) is generated and displayed on the display monitor 14. Furthermore, in order to implement various functions in the navigation device 1, the control unit 18 performs processing for allowing the user to intuitively select a desired operation item.

  FIG. 2 shows a state where an icon image to be operated when the user displays a list of operation items is displayed on the display monitor 14. The icon image is composed of a plurality of icons classified into two types by the two frames 31 and 32. For each icon, an illustration showing the type of icon is shown at the top of the icon, and characters showing the type of icon are shown at the bottom.

  In the frame 31 on the left side of the screen (hereinafter referred to as the left frame 31), five types of icons (option group) are shown. The icon shown in the left frame 31 is an object indicating a noun word (a word that can be an object) corresponding to a so-called “what” that is an object of the operation content. On the other hand, in the frame 32 on the right side of the screen (hereinafter referred to as the right frame 32), six types of icons (option groups) are shown, and the icon shown in the right frame 32 indicates the operation content. It is a verb, and is configured by an icon indicating a verb word (word that can specify an action) corresponding to so-called “how to”.

  Specifically, the icon shown in the left frame 31 includes an icon indicating “map”, an icon indicating “guidance”, an icon indicating “destination”, an icon indicating “route”, and “information” It is comprised by five types of icons with the icon which shows. The icons shown in the right frame 32 are an icon indicating “change”, an icon indicating “setting”, an icon indicating “display”, an icon indicating “erase”, and an icon indicating “search”. And six types of icons including an icon indicating “registration”.

  The number of icons and their contents shown in the left frame 31 and the number and contents of the icons shown in the right frame 32 are not limited to the numbers and their contents as shown in FIG. The icons shown in the left frame 31 may be less than 5 types or 6 or more types. Further, the icons shown in the right frame 32 may be less than six types, or may be seven or more types. However, if the number of icons is too large, it may be difficult to determine the type of icon at first glance. Therefore, it is desirable to determine the number of icons in consideration of user convenience.

  Further, the illustrations shown on each icon are shown so that the role of the button can be identified even by a child or a foreigner who cannot read the characters shown on the icon. Therefore, if the number of icons increases and the size of each icon decreases, it becomes difficult to recognize the icon illustrations. Therefore, it is preferable to determine the number of icons in consideration of icon visibility. .

  Since each icon has an illustration for identifying the icon, it is common even when the navigation device 1 according to the present embodiment is used (sold) in other countries having different languages. Icon can be used. Further, since the difference between the icons can be easily determined based on the image shown on the icon, it is possible to intuitively recognize and select the icon.

  In the navigation device 1 according to the present embodiment, when a user thinks to execute a predetermined function, first, the contents of the function are documented and specifically considered. Then, based on the sentenced function content, the user selects an icon indicating the closest semantic content to the object from the left frame 31 and indicates the semantic content closest to the verbal functional content verb. An icon is selected from the right frame 32. By selecting two types of icons in this way, a list of operation items that can realize the function content closest to the selected icon is displayed on the display monitor 14.

  For example, in the case of “setting a destination” in the navigation device 1, an icon indicating “destination” is selected from the left frame 31 on the touch panel, and an icon indicating “setting” is selected from the right frame 32 on the touch panel. Select with. An operation for realizing a desired function by documenting a desired function in this way and designating the object and verb of the functionalized function by selecting icons from the left and right frames 31 and 32. Items can be requested.

  In particular, the situation in which the navigation device 1 is operated is a situation in which it is not possible to spend time slowly on the operation, for example, before the vehicle starts, or when the vehicle is temporarily stopped by a signal or the like. There are many cases. For this reason, it is possible to easily find and operate an operation method for realizing a desired function simply by touching any icon of the left frame 31 and any icon of the right frame 32. Therefore, it is possible to speed up and simplify the operation process.

  Further, in the navigation device 1 according to the present embodiment, it is possible to display a list of operation items for realizing a desired function simply by touching two icons (with only two actions). Compared to the case where the three icons composed of “noun”, “particle”, and “verb” are touch-operated as in the conventional navigation device, the number of operation items extracted by the icons when the two icons are operated Tend to be wide (the number of items to be extracted increases).

  When three icons are operated, the extraction condition becomes finer in proportion to the number of icons. Therefore, it is possible to narrow down operation items with high accuracy by selecting an icon accurately (touch operation). However, if the wrong icon is selected due to misunderstanding, etc., there is a high possibility that the desired operation item will be removed from the narrowed operation items. As a result, the icon selection operation must be performed again from the beginning. There was a case that operation burden occurred.

  However, when two icons are operated, the extraction conditions are reduced as compared with the case where three icons are operated. For this reason, even if the selection of an icon is a little wrong or if the selection of an icon is lost, there is a high possibility that the target operation item is included in the narrowing down target, resulting in a re-operation. It is possible to reduce the operation burden.

  Note that the control unit 18 of the navigation device 1 acquires information regarding the type of icon touched by the user via the touch panel unit 15. When only one icon of the left frame 31 or the right frame 32 is selected and no icon is selected on the other frame, the control unit 18 displays the selected icon. Is changed to an icon image so that it can be visually recognized that the item is selected, and displayed on the display monitor 14.

  For example, as illustrated in FIG. 3A, when the “map” icon 41 of the left frame 31 is selected by touch operation, the control unit 18 determines that the “map” icon 41 is selected. A process of changing the display of the icon 41 is performed so that the user can visually recognize it. Similarly, as illustrated in FIG. 3B, when the “change” icon 42 of the right frame 32 is selected by touch operation, the control unit 18 selects the “change” icon 42. A process for changing the display of the icon 42 is performed so that the user can visually recognize the fact.

  In addition, when a predetermined icon is touch-operated, the control unit 18 obtains an icon in the other frame that cannot be combined with the touch-operated icon, and there is an icon corresponding to the impossible combination. In this case, the icon display in the other corresponding frame is changed to an icon image that cannot be selected and displayed on the display monitor 14.

  For example, as shown in FIG. 4A, when the “Guidance” icon 43 on the left frame 31 is selected by touch operation, first, the control unit 18 changes the display of the “Guidance” icon 43. Perform the process. Next, the control unit 18 obtains an icon that cannot be combined with the “guidance” icon 43 from the icons of the other frame (right frame 32). In the navigation apparatus 1 according to the present embodiment, as described below, the “search” icon 44 and the “registration” icon 45 cannot be combined with the “guidance” icon 43. Therefore, the control unit 18 performs a process of changing the “search” icon 44 and the “registration” icon 45 into icon images that cannot be selected by the user and displaying them on the display monitor 14.

  Similarly, as shown in FIG. 4B, when the “Register” icon 46 of the right frame 32 is selected by touch operation, the control unit 18 first selects the “Register” icon 46. Process to change the display. Next, the control unit 18 obtains an icon that cannot be combined with the “register” icon 46 from the icons of the other frame (left frame 31). In the navigation apparatus 1 according to the present embodiment, as described below, the “guidance” icon 47 and the “route” icon 48 cannot be combined with the “registration” icon 46. For this reason, the control unit 18 changes the “guidance” icon 47 and the “route” icon 48 to icon images that cannot be selected by the user and displays them on the display monitor 14.

  In this way, the icons that cannot be combined are changed to icon images that cannot be selected by the user and displayed on the display monitor 14 to select the icons of the respective frames that cannot be combined by the user. Can be effectively suppressed.

  In navigation device 1 according to the present embodiment, as shown in FIG. 5, whether or not operation items can be extracted according to the combination of the icon of left frame 31 and the icon of right frame 32 is determined. The shown data table is recorded in the map data recording unit 16. In FIG. 5, the combination indicated by “x” in the combination of the icon of the left frame 31 and the icon of the right frame 32 indicates a combination of icons that cannot be selected.

  For example, as shown in FIG. 4A, when the icon 43 indicating “Guidance” is selected in the left frame 31, the icon 44 indicating “Search” in the right frame 32 or “Register” is selected. The icon 45 shown cannot be selected. In a general car navigation system, although it is possible to perform “registration” of “destination”, it is not possible to perform “registration” of “guidance” (the function to “register” “guidance” is general) Not provided). For this reason, combinations of icons corresponding to functions not provided are indicated by “x” in the data table shown in FIG.

  On the other hand, in FIG. 5, the combination indicated by “◯” in the combination of the icon of the left frame 31 and the icon of the right frame 32 extracts some operation items based on the combination of the icons. It shows that it is possible to do. The operation items that can be extracted by the combination of icons are recorded in the map data recording unit 16 as a list. The control unit 18 determines whether or not the list of operation items can be extracted by referring to the data table of FIG. 5 based on the selected combination of icons. A process of displaying a list of the operation items obtained on the display monitor 14 is performed.

  FIG. 6 shows a list screen of operation items that are transitionally displayed when the icon indicating “map” is selected in the left frame 31 and the icon indicating “change” is selected in the right frame 32. By selecting two types of icons from the icon display screen shown in FIG. 2, etc., a list of operation items that can be extracted based on the selected icon is obtained as shown in FIG. Transitions will be displayed.

  In the navigation device 1 according to the present embodiment, about 10 to 12 operation items are displayed on the operation item list screen. The size of a display monitor of a general car navigation apparatus is about 5 to 7 inches. For this reason, if the size of characters of the extracted operation items is reduced and a large number of operation items are displayed on one screen, the characters may be too small and visibility and operability may be impaired. is there. On the other hand, if the characters are displayed too large, the number of operation items that can be displayed on one screen is reduced, so that the operation items are displayed on a plurality of pages, and the operation items can be confirmed and selected smoothly. It can be difficult.

  In consideration of such points, it is preferable to display about 5 to 6 items of operation items to be extracted per screen as shown in FIG. Can be easily and instantaneously determined. Furthermore, by displaying about 5 to 6 operation items on one screen, a list switching button (for example, the arrow buttons 50 and 51 shown in FIG. 6) provided on the display monitor 14 is operated only once. Since all the remaining operation items can be displayed on the screen, it is possible to easily recognize and select the operation items without increasing the operation load.

  FIG. 7 is a flowchart illustrating a process in which the control unit 18 displays a list of operation items on the display monitor 14 based on information related to the user's touch operation acquired from the touch panel unit 15.

  A standard screen of the navigation device 1 according to the present embodiment (a screen that is displayed at the time of route guidance or when the navigation device 1 is started, and generally corresponds to a display screen on which map data around the vehicle is displayed. .) Displays an icon button for changing the screen to an icon display screen. If necessary, the user can change the screen to an icon display screen as shown in FIG. 2 or the like by touching an icon button displayed on the standard screen of the display monitor 14.

  When the screen is changed to the icon display screen shown in FIG. 3, the control unit 18 performs a process (initial setting process) for initializing a predetermined area of the RAM 19 used for the determination process of the touched icon ( Step S.1). Specifically, a predetermined area in the RAM 19 is secured and data in the secured area is initialized in order to use it for determining an icon touch operation. Here, data initialization means processing for turning off a flag in a corresponding area (setting all bits in the corresponding area to zero). When any one of the icons is touched, the control unit 18 sets a predetermined flag preliminarily defined for each icon in a process described later (for example, the process of step S.14), thereby allowing the user to It records which icon is touched.

  Next, the control unit 18 acquires information related to the touch operation from the touch panel unit 15 (step S.2), and determines whether any icon is touched based on the acquired information (step S.2). S.3). When it is determined that none of the icons is touch-operated (No in step S.3), the control unit 18 repeatedly acquires information regarding the touch operation from the touch panel unit 15 (step S.2). The determination as to whether any of the icons has been touched is repeatedly executed (step S.3).

  If it is determined that any of the icons has been touched (Yes in step S.3), the control unit 18 reads the state of the flag corresponding to the type of the touched icon from a predetermined area of the RAM 19. (Step S.4), it is determined whether or not the flag of the touched icon is set (step S.5).

  When the flag of the touched icon is set (Yes in step S.5), the control unit 18 determines that the corresponding icon has been touched in a state where the icon has already been touch-selected. to decide. In this way, when an icon that has been touched once is touched again, the display content of the display monitor 14 is changed so that the corresponding icon is canceled, that is, the corresponding icon is not selected. Perform the correction (change) process.

  Specifically, the control unit 18 turns off flags relating to all icons including not only the selected (touch operation) frame but also an icon belonging to a frame different from the frame of the selected icon ( Step S.6). Then, the control unit 18 modifies the display of all icons to an icon image that is not selected based on the flag that has been turned off, and causes the display monitor 14 to display it (step S.7). In the icon correction display process on the display monitor 14, as described above, a display image is generated by the control unit 18 based on the icon image data recorded in the map data recording unit 16 and recorded in the image memory unit 13. Then, the display image recorded in the image memory unit 13 is output to the display monitor 14 and executed.

  Thereafter, the control unit 18 repeatedly performs the determination process (step S.2 and step S.3) on whether or not the above-described icon is touched.

  On the other hand, when it is determined that the flag of the touched icon is not set (when the flag of the touched icon is off: No in step S.5), the control unit 18 First, a flag state of an icon belonging to a different frame from the touch-operated icon and belonging to the different frame is read from a predetermined area of the RAM 19 (step S.8). Then, the control unit 18 determines whether or not there is a flag set in icons belonging to different frames based on the read flag states (step S.9). If the flag of any icon has already been set (Yes in step S.9), any icon belonging to a frame different from the frame of the touched icon has already been touched. It can be determined that the selected state has been selected.

  As described above, when an icon of a different frame is already selected (Yes in Step S.9), the control unit 18 is a frame that is different from the touch-operated icon and has already been selected. It is determined from the data table shown in FIG. 5 recorded in the RAM 19 whether or not the combination with the icon is possible (step S.10).

  If it is determined that the combination of icons is possible based on the data table recorded in the RAM 19 (Yes in step S.10), the control unit 18 sets a flag of the icon that has been touch-operated ( Step S.11). Then, the control unit 18 displays an icon (for example, a “guidance” icon shown in FIG. 4A) that allows the user to recognize that the icon has been selected by the touch operation. And display on the display monitor 14 (step S.12). Thereafter, the control unit 18 causes the screen to be displayed on the display monitor 14 to be transitionally displayed on a list screen of operation items that can be extracted based on the selected icon as shown in FIG. 6 (step S.13). The list display process ends.

  On the other hand, when it is determined that the combination of icons is impossible based on the data table recorded in the RAM 19 (No in step S.10), the control unit 18 is displayed on the display monitor 14. The processing is shifted to the above-described icon touch operation determination processing (step S.2 and step S.3) without changing the displayed content.

  When the combination of the icons is impossible, the control unit 18 does not perform the screen transition process of the display monitor 14 even when the touch operation of the icon is detected based on the information related to the touch operation. It is possible to make the user recognize that the operation has not been accepted.

  Further, step S.I. 9, if it is determined that the flag of any icon of a different frame has not been set (No in step S.9), the control unit 18 sets the flag of the touch-operated icon on. (Step S.14) The icon image on the display monitor 14 is changed to an image that can recognize that the icon has been selected (Step S.15).

  Thereafter, the control unit 18 determines whether there is an icon of another frame that cannot be combined with this icon by selecting the icon with the flag turned on, based on the data table shown in FIG. Judgment is made (step S.16). When there is an icon that cannot be combined according to the data table (Yes in step S.16), the control unit 18 selects display of icons of other frames that cannot be combined. The icon image cannot be changed to be displayed on the display monitor 14 (step S.17).

  For example, as shown in FIGS. 4A, 4B, and 5, a combination of a “guidance” icon and a “search” icon, a “guidance” icon, and a “registration” icon For the combination, the combination of the “root” icon and the “register” icon, there is no list of operation item candidates. For this reason, as described above, regarding the combination of these icons, the icon image is changed so that the corresponding icon of the other frame cannot be selected when the icon of one frame is selected, and the display monitor is changed. 14 is displayed.

  And step S.E. 16, when it is determined that there is no icon that cannot be combined (in the case of No in step S.16), or in step S.16. In 17, when the icon image of another frame is changed to an icon image that cannot be selected, the control unit 18 repeats the above-described icon touch operation determination process (steps S.2 and S.3). Run.

  In this way, the control unit 18 repeatedly executes the process until two kinds of icons that are allowed to be combined are selected as shown in FIG. 5 by touching the icons, and the icons are combined appropriately. In step S. As shown in FIG. 13, the display process is terminated by performing the list display process of the operation items.

  Further, in navigation device 1 according to the present embodiment, a list of operation items is defined so that the same operation items are extracted as a list even when the combinations of icons are different. FIG. 8 shows a list of operation items extracted when the “map” icon of the left frame 31 and the “change” icon of the right frame 32 are selected, and the “map” icon of the left frame 31. When the “setting” icon of the right frame 32 is selected, the list of operation items to be extracted, the “map” icon of the left frame 31, and the “display” icon of the right frame 32 are selected. It is the table | surface which showed the list of the operation item extracted in the case.

  In this combination of three patterns of icons, “change the map display method” (reference W1 in FIG. 8), “change the orientation of the map” (reference W2), “set the characters to be displayed on the map” (reference W3 ), “Set icon on map” (reference W4) corresponds to the operation items extracted in common.

  Thus, in the navigation device 1 according to the present embodiment, a list of operation items to be processed is obtained by combining two types of icons (an icon belonging to the left frame 31 and an icon belonging to the right frame 32). In the case of displaying, the operation items are not necessarily extracted corresponding to only one type of icon combination. In the navigation device 1, even when the combination of icons is selected to be different, when the common operation content can be imaged by the combination of the “verb” and “noun” of the selected icon, The same operation item is extracted as a list.

  As described above, in the navigation device 1 according to the present embodiment, since operation items are extracted by selecting two types of icons “noun” and “verb”, three or more types of icons are conventionally selected. It is possible to extract a desired operation item with a higher probability than that of the navigation device. Therefore, by selecting two types of icons, the user is more likely to display an operation list including a desired operation item on the display monitor 14 by the first icon selection, and the operation item is not extracted. Thus, it is possible to avoid a situation where the icon selection process has to be performed again.

  Furthermore, in the navigation device 1 according to the present embodiment, as shown in the flowchart in FIG. 7, the selection of two types of icons can be selected from the icons of the left frame 31 or the icons of the right frame 32. It is also possible to select. As described above, since any desired operation item list can be extracted and displayed on the display monitor 14 regardless of which icon is selected first, the degree of freedom of operation by the user can be increased.

  The information extraction apparatus according to the present invention has been described above with reference to the drawings. However, the information extraction apparatus according to the present invention is not limited to the configuration of the navigation apparatus 1 according to the above-described embodiment. . It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  Since the information extraction device according to the present invention can efficiently, intuitively and quickly extract information of a plurality of items only by selecting two icons, only the car navigation device shown as an example in the present embodiment. The present invention is not limited and can be applied to various devices such as mobile phones and bank ATMs.
