Description

  The present invention relates to an electronic device and an operation help presentation method, and is particularly suitable for an electronic device in which a plurality of types of methods are prepared as an operation method for executing one function.

  In general, a navigation device that guides driving of a vehicle not only displays a map around the current location, but also has a function of automatically setting and guiding a guidance route from the current location to the destination by specifying the destination. ing. In this type of navigation device, various operation methods are prepared as a user interface for inputting a destination.

  For example, (1) A facility name, a point name, a visited house name (friend's name, etc.), etc. are input with 50 sounds, (2) A facility is searched by phone number, (3) A facility is searched by address , (4) Search by facility genre, (5) Search by zip code, (6) Search by latitude / longitude, (7) Search for facilities near the current location, (8) Searching in the past There are a method of searching from a certain point and (9) a method of searching from a registered point.

  As described above, various types of facility search operation methods are prepared. However, knowledge and time are required for a user (particularly a beginner) to use these operation methods. Not only the facility search function of the navigation device but also an electronic device in which a plurality of types of methods are prepared as an operation method for executing one function. Knowledge and time are required to use various operation methods with such electronic devices.

In addition, there are electronic devices configured to explain operations by displaying a help display of functions (see, for example, Patent Documents 1 and 2). By using this help function, even if the user does not remember the operation method of all functions, it is possible to easily check the operation method of necessary functions when necessary.
Japanese Patent Laid-Open No. 11-231998 JP 2004-145681 A

  The technique described in Patent Document 1 displays help for an operation procedure of a function designated by the user, that is, a function that the user is going to use. The technique described in Patent Document 2 searches for and displays help information of functions stored as a user's key operation history so far when a help key is pressed.

  However, any of these help functions can be used when the user recognizes the existence of the function but does not know or remember the operation method. Therefore, when the user does not grasp the existence of the function itself, or when the function has never been used in the past, the help function as in Patent Documents 1 and 2 cannot be used.

  In addition, when the techniques described in Patent Documents 1 and 2 are applied to a navigation device that has a plurality of operation methods for one function (for example, a facility search function), an operation method designated by the user, It is possible to display the help of the operation method stored as the operation history. However, there is a problem that help display cannot be performed for an operation method that the user does not grasp in the first place and an operation method that has never been performed in the past.

  Actually, the user of the navigation apparatus often uses the few operation methods that he / she knows repeatedly. For this reason, even if there is a more efficient operation method for achieving the same purpose, the inefficient operation method is often repeatedly performed without knowing that.

  The present invention has been made to solve such a problem. In an electronic apparatus in which a plurality of operation methods exist for one function, a user actually performs one function with a certain operation method. The purpose is to be able to learn other operation methods while using.

  In order to solve the above-described problems, in the present invention, when the operation method history is stored, it is determined from the history information whether the currently operated operation method is the same as the past operation method, and is the same In addition, another operation method is presented to the user.

  According to the present invention configured as described above, when a user performs one function, if the user operates in the same manner as the operation method that has been performed in the past, another operation method different from that is operated as help. Will be presented. Thereby, the user can learn an unknown operation method of a plurality of patterns while actually performing the operation. For example, it becomes possible to know a more efficient operation method than the current operation method.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a navigation device which is an example of an electronic apparatus embodying the present invention. In this navigation device, a plurality of types of operation methods are prepared as operation methods for executing one function. For example, for one function of searching for a facility to be set as a destination of a guidance route, a 50 sound input search, a telephone number search, an address search, a genre search, a zip code search, a latitude / longitude search, a surrounding area search, a search There are several types of search methods such as location history search and registration point search.

  In FIG. 1, reference numeral 1 denotes a map recording medium such as a DVD-ROM, which stores map data necessary for map display, route search, and the like. Although the DVD-ROM 1 is used here as a recording medium for storing map data, other recording media such as a CD-ROM, a hard disk, and a semiconductor memory may be used. Reference numeral 2 denotes a DVD-ROM control unit which controls reading of data from the DVD-ROM 1.

  Reference numeral 3 denotes a position measuring device that measures the current position of the vehicle, and includes a self-contained navigation sensor, a GPS receiver, a position calculation CPU, and the like. The self-contained navigation sensor includes a vehicle speed sensor (distance sensor) that outputs a single pulse for each predetermined travel distance to detect the travel distance of the vehicle, and an angular velocity sensor such as a vibration gyro that detects the rotation angle (movement direction) of the vehicle. (Relative orientation sensor). The self-contained navigation sensor detects the relative position and direction of the vehicle using these vehicle speed sensor and angular velocity sensor.

  The position calculation CPU calculates the absolute own vehicle position (estimated vehicle position) and vehicle direction based on the relative position and direction data of the own vehicle output from the self-contained navigation sensor. The GPS receiver receives radio waves transmitted from a plurality of GPS satellites by a GPS antenna and performs a three-dimensional positioning process or a two-dimensional positioning process to calculate the absolute position and direction of the vehicle (the vehicle direction is The calculation is based on the current vehicle position and the current vehicle position one sampling time ΔT before).

  A map information memory 4 temporarily stores map data read from the DVD-ROM 1 under the control of the DVD-ROM control unit 2. In other words, the DVD-ROM control unit 2 inputs information on the current vehicle position from the position measuring device 3 and outputs an instruction to read out map data in a predetermined range including the current vehicle position, thereby displaying a map display and a guidance route. The map data necessary for the search is read from the DVD-ROM 1 and stored in the map information memory 4.

  Reference numeral 5 denotes a processor (CPU), which controls the entire navigation device. Reference numeral 6 denotes a ROM which stores various programs (such as a guidance route search program and an operation explanation presentation program). Reference numeral 7 denotes a RAM that temporarily stores data obtained in the course of various processes and data obtained as a result of various processes.

  The CPU 5 performs a process of searching for the route with the lowest cost connecting the current location to the destination using the map data stored in the map information memory 4 according to the guidance route search program stored in the ROM 6. Further, the CPU 5 performs a help display process for presenting the operation method to the user regarding the facility search method (operation method) when setting the destination in accordance with the operation explanation presenting program stored in the ROM 6. Details of this operation help presentation processing will be described later.

  Reference numeral 8 denotes a guidance route memory, which stores guidance route data set by the CPU 5 as described above. The guidance route data represents, for example, the position of each node from the current location to the destination. A display controller 9 generates map image data necessary for display on the display device 15 based on the map data stored in the map information memory 4.

  A video RAM 10 temporarily stores image data generated by the display controller 9. That is, the image data generated by the display controller 9 is temporarily stored in the video RAM 10, and image data for one screen is read and output to the image composition unit 14. Reference numeral 11 denotes a menu generation unit that generates and outputs a menu image necessary when the user performs various operations.

  A guidance route generator 12 generates drawing data for the guidance route using the result of the route search process stored in the guidance route memory 8. In other words, the guidance route generator 12 selectively reads out the guidance route data stored in the guidance route memory 8 from the map area drawn in the video RAM 10 at that time, Draws the guidance path boldly highlighted in different predetermined colors.

  A mark generation unit 13 generates and outputs a vehicle position mark displayed at the vehicle position after the map matching process, various landmarks displaying a gas station, a convenience store, and the like. Note that the map matching process includes the map data read into the map information memory 4, the vehicle position and vehicle orientation data measured by the GPS receiver measured by the position measuring device 3, and the estimated vehicle by the autonomous navigation sensor. This refers to processing for correcting the position of the vehicle on the road of the map data using the position and vehicle direction data.

  An image composition unit 14 synthesizes and outputs various images. That is, the map image data read out by the display controller 9 is superimposed on the image data output from each of the menu generation unit 11, the guidance route generation unit 12, and the mark generation unit 13 to perform image synthesis. The processed image data is output to the display device 15.

  The display device 15 includes a display panel 15a and a touch panel 15b. The display panel 15a displays a map image, operation help indicating the operation procedure of the facility search method, and the like. The touch panel 15b is superimposed on the front surface of the display panel 15a and detects a touch operation by the user. Then, the touch position of the user is detected and the coordinate data is output. The touch panel 15b allows the user to set various types of information (for example, a route guidance destination) to the navigation device, various types of operations (for example, menu selection operation, enlargement / reduction operation, manual map scrolling, numerical value input). Etc.).

  Reference numeral 16 denotes a history memory (corresponding to the history storage unit of the present invention), which stores a history of operation methods (operation procedures) that have been performed in the past with respect to execution of the facility search function. FIG. 2 is a diagram illustrating an example of an operation procedure for facility search. FIG. 3 is a diagram illustrating an example of history information stored in the history memory 16. When the operation shown in FIG. 2 is performed, the CPU 5 stores the operation procedure (each step of the key input operation) in the history memory 16 as the operation method history information as shown in FIG.

  When the history information as shown in FIG. 3 is stored in the history memory 16, the CPU 5 stores information related to the found facility in association with each other. Here, the information regarding the facility is, for example, a facility ID for specifying the facility. If the facility ID is stored, the CPU 5 refers to the map data using the facility ID as a key, so that detailed information on the facility (facility name, telephone number, address, genre, zip code, latitude / longitude, etc.) Information).

  Incidentally, the example of FIG. 2 shows an example in which a facility called “Catholic Yamate Church” is searched by the operation method of 50 sound input search. As shown in FIG. 3, in the history memory 16, touch operations for key input sequentially performed on the software keyboard displayed on the display panel 15a are stored side by side for each operation step. In this example, it is shown that the target facility has been detected in seven steps (seven key input touch operations).

  The CPU 5 described above compares the operation method currently performed for facility search through the touch panel 15b with the history information of the operation method stored in the history memory 16, and the operation method currently performed is the past. Determine if it is the same as one in the history. When the current operation method is one of the operation methods performed in the past, the CPU 5 controls the menu generation unit 11 to display a search method different from the currently performed operation method on the display panel 15a. Display as help above. Thus, CPU5 and menu generation part 11 are equivalent to the operation method presentation part of the present invention.

  FIG. 4 is a diagram illustrating an example of the above-described help display. FIG. 4 shows an example in which “Catholic Yamate Church” is searched by the same operation procedure as FIG. Among these, FIG. 4A shows a state at the start of the search, that is, a state where the search menu “input of facility 50 sound” is touched. FIG. 4B shows a state at the end of the search, that is, after key input is performed by the same operation procedure as shown in FIG. As shown in FIG. 4B, a help display field 20 is provided at the bottom of the display screen. Help display relating to other operation methods is performed on the help display field 20.

  The operation help presentation process will be described more specifically. When a series of user operations are performed for facility search, the CPU 5 sequentially stores a plurality of key input information (operation steps) related to the user operations in the RAM 7. Then, when all the operation steps necessary for the facility search are completed, the current user operation information stored in the RAM 7 is compared with the user operation history information stored in the history memory 16.

  As a result of the comparison, if the operation information in the RAM 7 and the operation history information in the history memory 16 are the same, the CPU 5 displays a help for an operation procedure of a search method different from the search method indicated by the operation information in the RAM 7. Control to display in the column 20. Preferably, a help is displayed for a search method that is different from the currently used search method and that is different from the history stored in the history memory 16.

  In the example of FIG. 4 (b), the operation procedure of the surrounding area search method is different from the actually performed 50-sound input search method and different from the history stored in the history memory 16, and the operation procedure of the surrounding area search method is key input. Displayed in step order. In this surrounding area search method, first, a button “search near” is touched as a search menu, and then a button “select facility” is touched. After that, when “Church” is designated as the facility genre, a list of churches is displayed. After that, it is possible to find “Catholic Yamate Church” by scrolling through the list. This series of operation procedures (excluding the last scroll) is displayed in the help display column 20.

  Here, the operation procedure of the search method displayed in the help display column 20 is prepared in advance as default information, for example. However, the fact that “Church” is displayed in the third step of the operation procedure in the help display column 20 is recognized based on the facility ID stored in the history memory 16 together with the history information of the operation method. . As described above, the CPU 5 can confirm that the facility genre of “Catholic Yamate Church” is “Church” by referring to the map data using the facility ID stored in the history memory 16 as a key. .

  If there are a plurality of search methods different from the currently used search methods and different from the history stored in the history memory 16, they are displayed in order as shown in FIG.

  Further, the search method for displaying the help may be limited to a search method in which the operation is completed with a smaller number of operation steps than the number of operation steps required for the currently performed search method. Specifically, the number of operation steps related to another search method that is not the current search method stored in the RAM 7 and is not the past search method stored as the history information in the history memory 16 is counted and stored in the RAM 7. The number of operation steps related to the stored current search method is counted, and both count values are compared. When the other search method has a smaller number of operation steps, the other search method is displayed in the help display column 20. Note that the count value of the operation step according to another search method may be prepared as a default together with the operation procedure information of the other search method.

  Further, when the number of operation steps is counted as described above, the total number of operation steps may be calculated by adding a weight according to the content of each operation step and performing weighted addition. For example, in the case of surrounding area search, a target facility can be searched in three steps as described above. In the third step, a target facility is searched by scrolling from a plurality of listed facilities. There must be. Considering this scrolling operation, for example, a double weight is added to the operation at the third step. In this case, the number of operation steps required for the peripheral area search is four steps.

  FIG. 6 is a flowchart showing an operation example of the navigation device configured as described above. In FIG. 6, first, the CPU 5 determines whether or not a facility search process is being performed (step S1). Specifically, it is determined whether or not a menu prepared for facility search is operated to enter the facility search mode. If the facility search process has not been performed, the process of this flowchart ends.

  On the other hand, when the facility search process is being performed, the CPU 5 sequentially stores the operation steps being operated by the current search method in the RAM 7 (step S2). Then, it is determined whether or not a series of operation steps related to the operation method currently being performed for facility search is completed (step S3). Specifically, it is determined whether or not the last step operation in a series of operation procedures necessary for the search method has been performed.

  Here, when it is determined that a series of operation steps has not been completed yet, the process returns to step S1 and the facility search process is continued. On the other hand, if it is determined that all the series of operation steps have been completed, the CPU 5 stores information on the operation method stored in the RAM 7 in the course of the series of operations, history information on the operation method stored in the history memory 16, and Are compared (step S4). Then, as a result of the comparison, it is determined whether the history information in the history memory 16 has the same information as the current operation method stored in the RAM 7 (step S5).

  If it is determined that the operation method actually performed is the same as one of the operation methods indicated by the history information, the CPU 5 is different from the operation method currently performed and is stored in the history memory 16. An operation method different from the history of the current operation method is displayed in the help display field 20 (step S6). At this time, the display may be limited to the operation method in which the operation is completed with the number of operation steps smaller than the number of operation steps necessary for the operation method currently performed.

  On the other hand, when it is determined that there is no history information in the history memory 16 that is the same as the current operation method stored in the RAM 7, the CPU 5 uses the operation method information stored in the RAM 7 as the operation method information. The new history information is stored in the history memory 16 (step S7). And the process of this flowchart is complete | finished after the process of step S6 or step S7.

  As described above in detail, according to the present embodiment, the operation history when the facility search process is performed is stored in the history memory 16. Then, it is determined from the history information whether the search method currently performed at an arbitrary time is the same as the past search method, and when it is the same, another operation method is presented to the user. . As a result, when the user performs the facility search function, if the user operates in the same manner as the search method that has been performed in the past, another search method different from that is dynamically presented as help. Therefore, the user can learn a search method for a plurality of patterns while actually performing an operation. For example, when an inefficient search method is repeatedly performed, the user can know a more efficient operation method.

  In the above embodiment, an example has been described in which help display is performed as necessary when a series of operation steps related to the operation method currently being performed in order to execute the facility search function is completed. Is not limited to this. For example, in the course of a series of operation steps being performed, each time an operation method is executed sequentially (every time one operation step is executed), history information of the operation method currently stored and the operation method history information stored in the history memory 16 are obtained. In comparison, a refinement search using the same operation method as that currently performed may be performed.

  For example, when a series of operations as shown in FIG. 2 is performed, whether or not the same operation history is stored in the history memory 16 when the search menu “input facility 50 sound” is first touched. Determine. At this time, if there is no corresponding operation history, help display is not performed, and the operation content is stored in the history memory 16 as a new operation history when a series of operation steps are completed. If there is only one corresponding operation history, help display is immediately performed at that time.

  If there are a plurality of corresponding operation histories, the system waits for the next key input operation to be performed. When the next key input operation is performed, it is determined again whether or not the same operation history as the previous operation procedure is stored in the history memory 16. In the example of FIG. 2, when the character “ka” is touched, it is determined whether or not an operation history of “facility 50 sound input” → “ka” is not stored in the history memory 16. If there are a plurality of corresponding operation histories at this stage, the same processing is performed thereafter. Then, when the corresponding operation history is narrowed down to one, help display is performed.

  FIG. 7 is a flowchart showing an example of the operation of the navigation apparatus when the help display is performed in this way. In FIG. 7, first, the CPU 5 determines whether or not the facility search process is being performed (step S11). Specifically, it is determined whether or not a menu prepared for facility search is operated to enter the facility search mode. If the facility search process has not been performed, the process of this flowchart ends.

  On the other hand, when the facility search process is being performed, the CPU 5 determines whether or not one of the operation steps being operated by the current search method has ended (step S12). Here, if it is determined that one operation step has not yet been completed, that is, if it is determined that the next operation has not yet been performed following the previous operation, the process returns to step S11 and the facility search process is performed. continue.

  On the other hand, when determining that one operation step is completed, the CPU 5 stores the operation step in the RAM 7 (step S13). At this time, the CPU 5 compares the information related to the user operation stored in the RAM 7 with the history information of the user operation stored in the history memory 16 (step S14). Then, as a result of the comparison, it is determined whether the history information in the history memory 16 has the same information as the current user operation stored in the RAM 7 (step S15).

  Here, when it is determined that the history information in the history memory 16 includes the same information as the current user operation stored in the RAM 7, the CPU 5 has one history of the same user operation as the current user operation. It is further determined whether or not it has been narrowed down (step S16). If it is determined that the number is limited to one, the CPU 5 displays a search method that is different from the currently performed user operation and different from the user operation history stored in the history memory 16 in the help display column 20. (Step S17). Here, the search method may be limited to the search method in which the operation is completed with the number of operation steps smaller than the number of operation steps necessary for the user operation currently performed.

  On the other hand, if it is determined that there are still a plurality of user operation histories that are the same as the current user operation, the process returns to step S11 to continue the facility search process. If it is determined in step S15 that the history information in the history memory 16 is not the same as the current user operation stored in the RAM 7, the CPU 5 determines whether the user is currently performing a facility search. It is determined whether or not a series of operation steps related to the operation has been completed (step S18).

  Here, when it is determined that the series of operation steps has not been completed yet, the process returns to step S11 and the facility search process is continued. On the other hand, when determining that all the series of operation steps have been completed, the CPU 5 stores the information on the series of operation steps stored in the RAM 7 in the history memory 16 as new history information of the operation method (step S19). . And the process of this flowchart is complete | finished after the process of step S17 or step S19.

  In the case of operating in accordance with the flowchart shown in FIG. 7, when the help display is performed in step S17, for example, by touching the operation menu displayed in the help display column 20, a facility search method is provided. You may make it switch from the middle. For example, when a two-step operation such as “facility 50 sound input” → “ka” is performed, the same operation history is narrowed down to one and a help display is displayed as shown in FIG. In addition, by touching the display position of “search near” in the help display field 20, it is possible to switch to the peripheral area search that allows more efficient search. Further, by touching the display position of “Church” in the help display column 20, the operation may be automatically advanced to the place where the facility genre is designated as “Church” by switching to the surrounding area search.

  Moreover, although the said embodiment demonstrated the example which performs a help display at the time of execution of the facility search function of a navigation apparatus, this invention is not limited to this. That is, the “one function” according to the present invention is not limited to the facility search function. Moreover, although the navigation apparatus was mentioned and demonstrated in the said embodiment as an example of an electronic device, the applicable electronic device is not limited to this. For example, the present invention can be applied to electronic devices such as a mobile phone, a personal computer, a PDA (Personal Digital Assistance), a facsimile, a DVD (Digital Versatile Disk) recorder, and a portable audio player.

  FIG. 8 is a diagram showing an example when the present invention is applied to a mobile phone. FIG. 8A shows an operation method actually performed when inputting a telephone number. Here, an example is shown in which all numbers of telephone numbers are input by a key input operation. On the other hand, FIG. 8B shows a state in which help display is performed in the help display column 20 because the operation method as shown in FIG. 8A is stored in the history memory. Here, help is displayed that the same telephone number can be designated from the incoming call history by a two-step operation of “MENU” + “0”.

  In addition, each of the above-described embodiments is merely an example of actualization in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
