Description

  The present invention relates to an electronic device that displays a plurality of stored point information in a list format in order to select a destination, and more particularly to a sorting method thereof.

2. Description of the Related Art Conventionally, a navigation apparatus has a function of allowing a user to freely register points on a map, such as a place where they often go, a place they are interested in, and a favorite place, in addition to registering a home. For example, when the location registration operation is performed by moving the cursor to a desired position on the map displayed on the display, the navigation device stores the latitude and longitude of the location and also registers the registered location (hereinafter referred to as a registered location). ) Is acquired from the map data as the name of the cursor position and stored in association with the registered location. Information (name, latitude / longitude, telephone number, address, etc.) associated with this registration point can be arbitrarily changed by the user.
Further, in this type of navigation device, the registration point registered by the user can be set as the destination, and the route to the registration point set as the destination can be guided. Registration of this registered point can be performed not only for one point but also for a plurality of points. For example, when setting a destination from a plurality of registered points to a desired registered point, A desired registration point is searched from the displayed list (registration point list) and selected to set the destination.

At this time, if there are many registered points registered by the user, the number of display items in the registered point list increases. It is very difficult to find one desired point from among them. Therefore, a technique for sorting the display order so that a desired point can be easily selected from a list having a large number of items to be displayed is disclosed.
For example, Patent Document 1 stores a history of points set as destinations in the past and destinations for the destinations, and when displaying a list of destination histories, a technique of sorting in descending order of the number of times set for destinations. Is disclosed.
Further, in Patent Document 2, a destination setting history that is a set of the vehicle position and the date and time when a destination and a destination set in the past are set is registered. A technology that extracts the points where the destination setting operation exists around the current vehicle position, and sorts the destination setting history in descending order of the date and time when the destination setting operation was displayed when displaying the extracted destination setting history Is disclosed.

Will be described assuming that the set number of times and the number of times of arrival are stored for each of the five registered points as shown in FIG.
In addition, an example in which the set number of times and the number of arrivals are stored in the count information table will be described. However, the set number of times and the number of arrivals may be stored in association with the registration point table, or stored as one item of the registration point record. You can also. Further, the map DB 21 and the registered spot data 22 can be acquired from a server connected to the external I / F 15.

  The program memory 25 stores various programs executed by the control unit 30 and application data. The main programs executed by the navigation device 1 include a registration point control program 251, a current position specifying program 252, a destination setting program 253, a route search program 254, a guidance guide program 255, a set count count program 256, and an arrival determination program 257. There are an arrival count program 258 and a registration point list display program 259.

  The registration point control program 251 performs various controls such as addition, deletion, and editing of the registration point data 22 in the data memory 20. Specifically, when a registration point start instruction is input from the input unit 10, the registration point control program 251 detects the position of the point from the map data in the data memory 20 with respect to the point specified for performing the point registration. While reading the coordinates, information such as the spot name of the spot, the reading name of the spot name, the phone number, and the address related to the position coordinates is acquired. And using these acquired information, a registration point edit screen (Drawing 3) is generated, and it outputs to display output part 14, and display output part 14 displays on display 14A. This registered point editing screen shown in FIG. 3 is a screen on which a user can freely input and edit a point name, a reading of the point name, a telephone number, an address, a position coordinate, a map display mark, a memo, and the like. If the location information related to the position coordinates does not exist or cannot be specified, the corresponding item on the registered location editing screen is left blank. When the user inputs and edits each information from the registration point editing screen and a point registration instruction is input, the input information is used as the registration point information, and information on a predetermined registration point ID is given to the data memory. It is stored in the 20 registered spot data 22. In this way, a registered point is added to the registered point data 22.

Furthermore, when the registration point control program 251 receives an instruction to edit the registered spot information registered from the input unit 10, the registration spot control program 251 acquires the registration spot information of the registered spot that is instructed to edit from the registration spot data 22 in the data memory 20. A registration point edit screen using the registration point information is generated and output to the display output unit 14, and the display output unit 14 displays it on the display 14A. And when a user edits each information from a registration point edit screen and the edit completion instruction | indication is input, the information edited with respect to the said registration point is overwritten and memorize | stored.
When a registration point information deletion instruction is input from the input unit 10, the registration point control program 251 deletes the registration point information of the registration point instructed to be deleted from the registration point data 22 of the data memory 20.

  The current position specifying program 252 specifies the current position based on detection signals from the GPS receiver 11 and the autonomous navigation sensor 12. At this time, if necessary, processing such as map matching is also performed based on the map data in the data memory 20.

  The destination setting program 253 sets a facility, a point, and the like selected and designated by the user as a destination. The destination is set by searching facility information data in the map data, searching the cursor position on the map, registration point data, searching the destination setting history, or the like. For example, the destination setting program 253 sets a registered point selected from the registered point list as a destination, and provides the information to the route search program 254.

  The route search program 254 searches for an optimum guidance route from the current position specified by the current position specifying program 252 or a position specified by another user to the destination set by the destination setting program 253. The search for the guide route is based on a well-known algorithm such as the Dijkstra method, and the predetermined conditions (the route with the shortest distance, the route with the shortest time, the route using only a general road, the route using a wide road, etc.) Searched to meet.

  The guidance guidance program 255 provides guidance guidance voice data to the voice output unit 13 based on the optimum route searched by the route search program 254, and guide guidance image data (for example, an enlarged view of an intersection) to the display output unit 14. Various controls related to guidance and guidance are provided.

  The set number count program 256 counts the number of times (set number) set with each registered point as the destination. Specifically, when the destination is set by the destination setting program 253, it is determined whether or not the destination is a registered point. If the destination is a registered point, the count information table of the data memory 20 is determined. Then, 1 is added to the set number of times for the registration point. In addition, although the example which adds 1 whenever it sets to a destination is demonstrated as a preferable aspect, the count value of this setting frequency | count can be changed into any aspect if the frequency | count can be judged as another aspect. Is possible.

  The arrival determination program 257 determines whether or not the current position specified by the current position specifying program 252 has arrived at any of the registered points stored in the registered point data 22 of the data memory 20. Specifically, the current position specified by the current position specifying program 252 approaches within a predetermined distance from any position information of each registered point in the registered point data, and the navigation device 1 is turned off. It is determined that it has arrived at the registration point. Or, when the current position specified by the current position specifying program 252 approaches within a predetermined distance with respect to any position information of each registered point of the registered point data and has stopped at that point for a predetermined time or more It is determined that the user has arrived at the registration point. The result of the arrival determination is provided to the arrival number counting program 258.

  The arrival count program 258 counts the number of arrivals (arrival times) at each registered point. Specifically, when it is determined that the arrival determination program 257 has arrived, 1 is added to the number of arrivals at the registration point in the count information table of the data memory 20. In addition, although the example which adds 1 whenever it arrives at a registration point is demonstrated as a preferable aspect, the count value of this arrival frequency can be changed into any aspect if the frequency | count can be judged as another aspect. It is.

  The registered spot list display program 259 generates a registered spot list according to an instruction from the user, and outputs the registered spot list to the display output unit 14. The display output unit 14 displays the registered spot list on the display 14A. Details of the registration point list display program 259 will be described later.

  The control unit 30 includes devices such as a central processing unit, a microcomputer, or a microprocessor, and executes various programs stored in the program memory 25 to control each unit of the navigation device 1.

  Next, FIG. 4 shows a functional configuration block diagram related to the registration point list display control of the navigation device 1 of the first embodiment. As shown in FIG. 4, the registration point list display program 259 performs sorting that sorts the registration points based on the calculation result of the calculation unit 261 and the calculation unit 261 that perform a predetermined calculation using the set number of times and the number of arrivals of the count information table. 262, and a list generation unit 263 that generates a registered spot list based on the sorting result of the sorting unit 262.

  The calculation unit 261 obtains the set number of times and the number of arrivals for each registration point from the count information table of the data memory 20, and uses the obtained information to subtract the set number of times from the set number of times and the number of arrivals (for example, the number of arrivals). (The number of arrivals−the set number of times; the first difference)). Then, the calculation unit 261 provides the calculation result to the sorting unit 262. Specifically, the calculation unit 261 acquires the set number of times “3” and the number of arrivals “3” for the point A from the count information table of FIG. 2B, and calculates the set number of times “3” from the number of arrivals “3”. Subtraction is performed to obtain the value “0”. Similarly, the set number “30” and the arrival number “42” of the point B are acquired, and the set number “30” is subtracted from the arrival number “42” to obtain the value “12”. Similarly, the calculation unit 261 obtains a first difference between the set number of times and the arrival number for every registration point, and provides the calculation result to the sort unit 262.

  In the following description, an example will be described in which the calculation unit 261 obtains a value obtained by subtracting the set number from the number of arrivals as described above. However, the present invention is not limited thereto, and the number of arrivals is subtracted from the set number (set number−arrival number). Second difference). Furthermore, the ratio between the number of arrivals and the set number of times may be obtained. In the calculation of the ratio between the number of arrivals and the set number of times, the ratio of the set number of times to the number of arrivals (set number of times / arrival times × 100; first ratio) and the ratio of the number of arrivals to the set number of times (arrival times / set number of times × 100; 2 ratio) can also be calculated.

  The sorting unit 262 arranges the registration points according to the calculation result by the calculation unit 261. Specifically, when the difference between the number of arrivals and the set number of times for each registered point is provided from the calculation unit 261, the registered points are arranged in ascending order of the difference. That is, since the difference at the point A is “0” and the difference at the point B is “12”, the point A is rearranged so that the point A is higher in the list than the point B. Here, when the calculation result provided from the calculation unit 261 is a negative number, it can be handled as “0”.

Note that when the calculation unit 261 is configured to calculate the second difference (“set number of times−number of arrivals”), the sort unit 262 rearranges the registration points in descending order of the second difference. Configured. Further, when the calculation unit 261 is configured to calculate the first ratio (“set number of times / arrival times × 100”), the sort unit 262 arranges the registration points in descending order of the first ratio. When the calculation unit 261 is configured to calculate the second ratio (“number of arrivals / set number of times × 100”), the sorting unit 262 determines that the second ratio is in ascending order. It is configured to sort the registration points.
Furthermore, when the calculation results provided from the calculation unit 261 are the same, the sorting unit 262 arranges the ones with a larger number of either the set number of times or the number of arrivals so as to be higher. If the number of times is also the same, the registration points are arranged based on the order of the registration point IDs and the alphabetical order of the point names.

  The list generation unit 263 generates a registration point list so that the registration points arranged by the sorting unit 262 are displayed in the order in which they are arranged. The generated registration spot list is output to the display output unit 14, and the display output unit 14 displays it on the display 14A. If there are more registered spot lists than can be displayed as a list at a time, the display output unit 14 can display lower registered spots that are not displayed by the scroll key.

Next, the registration point list display operation of the navigation device 1 configured as described above will be described with reference to FIG.
When a user inputs a destination setting operation for setting a desired facility or point as a destination through the input unit 10, the control unit 30 displays a destination setting menu screen (how to search for the facility or point). 6) is generated and displayed on the display 14A by the display output unit 14 (step S101). As shown in FIG. 6, this destination setting menu screen is searched by a facility name search key for searching by facility name, an address search key for searching by address, a telephone number search key for searching by telephone number, and a genre of facility. A genre search key for performing a search, a map search key for selecting a point on the map with a cursor, a registered point search key (Key1) for searching from a registered point stored in the data memory 20, and a destination for searching from destination history information Search key is placed.

  When the user selects a registered point search key (Key 1) from the destination setting menu screen (step S103), a registration point list display instruction is output from the input unit 10 to the control unit 30. In response to the instruction, the calculation unit 261 reads the set number of times and the number of arrivals from the registered point data 22, and calculates the difference between the set number of times and the number of arrivals (arrival number−set number of times) for each registered point (step S105). On the other hand, when a search method other than the registered point search is selected from the destination setting menu screen, the facility or the point to be set as the destination is searched for using the selected search method by a known algorithm. The calculating unit 261 provides the sorting unit 262 with the result calculated for each registered location.

  The sorting unit 262 arranges the registration points in ascending order of the difference value based on the calculation result (number of arrivals−set number of times) provided from the calculation unit 261. The list generation unit 263 generates a registration point list from the registration points arranged by the sorting unit 262 such that the registration point having a small difference value is higher (step S107).

  Then, the list generation unit 263 outputs the generated registered spot list to the display output unit 14, and the display output unit 14 displays the registered spot list on the display 14A (step S109). By selecting a desired registration point from the displayed registration point list using the input unit 10, the details of the selected registration point can be displayed or the destination can be set.

  Specifically, when five registered points from point A to point E shown in FIG. 2B are stored in the registered point data 22, the calculation unit 261 calculates the set number of times from the number of arrivals for each registered point. As a result of the subtraction, the point A is “0”, the point B is “12”, the point C is “5”, the point D is “4”, and the point E is “−1” (FIG. 7A )). Then, the calculation unit 261 provides the calculated calculation result to the sorting unit 262, and the sorting unit 262 determines the point E, the point A, the point D, The points C and B are arranged in this order.

  Then, the list generation unit 263 generates a registration spot list in the order of the spot E, the spot A, the spot D, the spot C, and the spot B so that the registration spot with a small difference becomes higher in the list (FIG. 7 ( b)) The generated registration point list is output to the display output unit 14. Then, the display output unit 14 displays the registered spot list on the display 14A.

  As described above, according to the first embodiment, the navigation device 1 sets the registration points in ascending order of the difference based on the number of times set for the destination and the number of arrivals at the registration point for each registration point. Since the registered point list is displayed, the display priority of the point information that the destination setting seems unnecessary for the user is lowered, and the display priority of the point information that the user seems to need the destination setting is increased. be able to.

  In the first embodiment described above, the calculation unit 261 calculates the first difference (number of arrivals−set number of times) and sorts based on the calculation result. However, the second difference (set number of times) -Number of arrivals), first ratio (set number / number of arrivals x 100), second ratio (number of arrivals / number of set times x 100), and sorting unit 272 rearranges based on the calculation result. Is also possible.

  The calculation result and the display order of the registered spot list at this time will be described with reference to FIG. FIG. 8A shows an example in which the second difference (the set number of times−the number of arrivals) is calculated. As illustrated in FIG. 8A-1, the calculation unit 261 calculates the calculation result as follows: the point A is “0”, the point B is “−12”, the point C is “−5”, and the point D is “−4”. ", Point E seeks" 1 ". Then, as shown in FIG. 8A-2, the sorting unit 262 arranges the list in the order of point E, point A, point D, point C, point B in descending order of the calculation result (second difference). The registration point list according to this order is generated by the generation unit 263.

  FIG. 8B is an example when the first ratio (the set number of times / the number of arrival times × 100) is calculated. As shown in FIG. 8B-1, the calculation unit 261 calculates the calculation result as follows: the point A is “100%”, the point B is “71%”, the point C is “50%”, and the point D is “67”. % "And point E seeks" 200% ". And as shown in FIG.8 (b-2), the sort part 262 arranges in order of the point E, the point A, the point B, the point D, and the point C in order with a big calculation result (1st ratio), and lists it. A registration point list according to this order is generated by the generation 263.

  FIG. 8C is an example when the second ratio (number of arrivals / number of arrivals × 100) is calculated. As shown in FIG. 8C-1, the calculation unit 261 calculates the calculation result as follows: the point A is “100%”, the point B is “140%”, the point C is “200%”, and the point D is “150”. % "And point E asks for" 50% ". And as shown in FIG.8 (c-2), the sort part 262 arranges the list in order of the point E, the point A, the point B, the point D, and the point C in order with a small calculation result (2nd ratio). A registration point list according to this order is generated by the generation 263.

  Thus, even when the calculation method is changed, the display priority of point information that does not require destination setting for the user can be lowered, and the display priority of point information that requires destination setting by the user can be increased. it can.

  In the first embodiment described above, when a search from a registered location is selected in step S103, that is, when an instruction to display a registered location list is input, the computing unit 261 performs a predetermined computation, Although the sort part 262 demonstrated the example which determines the arrangement | sequence order of a registration spot using the calculation result, it is not limited to this. For example, the calculation unit 261 performs the predetermined calculation described above every time the set number count program 256 counts the set number of times and the arrival number count program 258 counts the set number of times, and the calculation result is stored as data. It is stored in the count information table of the memory 20 (FIG. 9). Then, when an instruction to display the registration spot list is output from the input unit 10 to the control unit 30, the sorting unit 262 can obtain the calculation result from the count information table and arrange the registration points. .

Next, a second embodiment of the present invention will be described. In addition, about the same structure as 1st Example, the same code number is attached | subjected and the description is abbreviate | omitted FIG. 10 is a figure which shows the structure of the navigation apparatus 2 which concerns on 2nd Example of this invention. is there. In the figure, a navigation device 2 displays an input unit 10 constituting a user interface, a GPS receiver 11, an autonomous navigation sensor 12, an audio output unit 13 for outputting audio from a speaker 13A, and various images and videos.

However, it should be noted that the configuration of the navigation device 2 illustrated in FIG. 10 is an example.

  When the navigation device 2 is activated, the date / time detection unit 16 detects current date / time information based on a signal from an internal timer backed up by a battery, and provides this to the control unit 31. If the current date and time information cannot be obtained by the date and time detection unit 16, the current date and time information can be obtained from another electronic device connected to the external I / F 15. It is also possible to detect current date and time information using various radio waves. For example, when the GPS receiver 11 receives information from a GPS satellite or the navigation device 2 has a broadcast wave reception function, the current date and time information can be detected from the information from the received broadcast wave.

The data memory 23 is a storage device such as an HDD or a flash memory, and stores the map DB 21 and registration point data 24. The registered spot data 24 can be stored so as to be included in the map DB 21.
The registered spot data 24 is data for accumulating information on spots registered by the user, and includes a registered spot table, a registered spot record (a), and a count information table (b) as shown in FIG. The Since the configuration of the registration point table and the registration point record is the same as that of the first embodiment, description thereof is omitted.

  As shown in FIG. 11B, the count information table includes, for each registered point, the name of the point, the number of times that the registered point is set as the destination (hereinafter, the set number of times), and the number of times of arrival at the registered point ( Hereinafter, the number of arrivals) and the last arrival date and time information for the last arrival at the registration point are stored in association with each other. In addition, you may make it memorize | store a setting frequency | count, arrival frequency, and the last arrival date in association using registered location ID instead of a location name.

Hereinafter, the registration point record has already stored five registration points of point A, point B, point C, point D, and point E by the processing of the registration point control program 251, and the count information table includes: As shown in FIG. 11 (b), it is assumed that the set number of times, the number of times of arrival, and the final arrival date / time information are stored for five registration points.
Further, an example in which the set number of times, the number of arrivals, and the last arrival date and time information are stored in the count information table will be described, but the set number of times, the number of arrivals, and the last arrival date and time information may be stored in association with the registration point table, It can also be stored as a registration point record.
Further, the map DB 21 and the registered spot data 24 can be acquired from a server connected to the external I / F 15.

  The program memory 25B stores various programs executed by the control unit 31 and application data. The main programs executed by the navigation device 1 include a registration point control program 251, a current position specifying program 252, a destination setting program 253, a route search program 254, a guidance guide program 255, a set count count program 256, and an arrival determination program 257 </ b> B. There are an arrival count program 258 and a registration point list display program 259B.

  The arrival determination program 257B determines whether or not the current position specified by the current position specifying program 252 has arrived at any of the registered points stored in the registered point data 24 of the data memory 23. Specifically, the current position specified by the current position specifying program 252 approaches within a predetermined distance from any position information of each registered point in the registered point data, and the navigation device 2 is turned off. It is determined that it has arrived at the registration point. Or, when the current position specified by the current position specifying program 252 approaches within a predetermined distance with respect to any position information of each registered point of the registered point data and has stopped at that point for a predetermined time or more It is determined that the user has arrived at the registration point. The result of the arrival determination is provided to the arrival number counting program 258.

  When the arrival determination program 257B determines that it has arrived at the registered location, the current date / time information provided from the date / time detection unit 16 is used as the final arrival date / time information, and the count information table of the data memory 23 for the registered location for which the arrival has been determined. To remember.

  The registered spot list display program 259B generates a registered spot list according to an instruction from the user, and outputs the registered spot list to the display output unit 14. The display output unit 14 displays the registered spot list on the display 14A. Details of the registered spot list display program 259B will be described later.

  The control unit 31 includes a device such as a central processing unit, a microcomputer, or a microprocessor, executes various programs stored in the program memory 25B, and controls each unit of the navigation device 2.

  Next, FIG. 12 shows a functional configuration block diagram related to the registration point list display control of the navigation device 2 of the second embodiment. As shown in FIG. 12, the registration point list display program 259B includes a time measuring unit 271 that measures the elapsed time between two pieces of time information, and a calculation unit that performs a predetermined calculation using the number of times set and the number of arrivals in the count information table. 272, the adjusting unit 273 that adjusts the calculation result of the calculating unit 272 according to the elapsed time from the time measuring unit 271, the sorting unit 274 that sorts the registration points based on the adjustment result of the adjusting unit 273, and the sorting result of the sorting unit 274 And a list generation unit 275 that generates a registration point list based on the above.

The time measuring unit 271 measures the number of days elapsed between the last arrival date information stored in the count information table of the registration spot data 24 and the current date information detected by the date detection unit 16. Then, the timekeeping unit 271 provides the timekeeping result to the adjustment unit 273.
For example, when the current date and time detected by the date and time detection unit 16 is 2013/12/31 12:00 and the last arrival date and time of the point A is 2013/11/30 12:00, the time measuring unit 271 It is timed that one month and one day have passed since the last arrival.

The calculation unit 272 acquires the set number of times and the number of arrivals for each registration point from the count information table in the data memory 23, and subtracts the set number of times from the number of arrivals and the set number of times (for example, the number of arrivals) using the acquired information. (The number of arrivals−the set number of times; the first difference)). Then, the calculation unit 272 provides the calculation result to the adjustment unit 272. Specifically, the calculation unit 272 acquires the set number of times “3” and the number of arrivals “3” of the point A from the count information table, subtracts the set number of times “3” from the number of arrivals “3”, and sets the value “ 0 ”is obtained. Similarly, the set number “30” and the arrival number “42” of the point B are acquired, and the set number “30” is subtracted from the arrival number “42” to obtain the value “12”. Similarly, the calculation unit 272 obtains a first difference between the set number of times and the arrival number for every registered point, and provides the calculation result to the adjustment unit 273.
Note that the calculation unit 272 may obtain the second difference, the first ratio, and the second ratio in the same manner as the calculation unit 261 of the first embodiment.

  When the timing result from the timing unit 271 and the calculation result from the calculation unit 272 are provided, the adjustment unit 273 adjusts the calculation result according to the timing result. For example, the adjustment unit 273 divides the calculation result of the registration point by a predetermined value for a registration point that has passed a predetermined period (for example, one month) from the last arrival date based on the elapsed days information from the time measuring unit 271. (For example, halve) and adjust the calculation result. Alternatively, the calculation result of the registration point is subtracted by a predetermined value, and the calculation result is adjusted. Then, the adjustment unit 273 provides the sorting unit 274 with the calculation result (adjustment value) adjusted for each registration point. The adjustment unit 273 performs adjustment by a predetermined value every time a predetermined period elapses.

  Specifically, when “0” is provided as the calculation result for the point A from the calculation unit 272, the adjustment unit 273 calculates the calculation based on the elapsed days (one month and one day) provided from the time measurement unit 271. Halve the result and adjust to “0”. Similarly, when “12” is provided as the calculation result for the point B, the calculation result is halved twice and adjusted to “3” based on the elapsed days (two months and three days) provided from the time measuring unit 271. To do. Similarly, the calculation result provided from the calculating part 272 is adjusted with respect to all the registration points according to the elapsed days provided from the time measuring part 271 to obtain an adjustment value. Then, the adjustment values of all the registration points are provided to the sorting unit 274. In addition, when the calculating part 272 is a structure which calculates | requires a 2nd difference or a 1st ratio and a 2nd ratio, the value is adjusted based on elapsed days.

  In the following description, an example in which adjustment is performed with a predetermined value every time a predetermined period elapses will be described. However, the present invention is not limited to this, and adjustment with a predetermined value proportional to the number of elapsed days is also possible. For example, it may be adjusted such that 10% decrease after one week, 20% decrease after one month, 30% decrease after three months, and 50% decrease after half a year. Alternatively, it may be determined simply whether or not the number of elapsed days has elapsed, and only the registration points after the predetermined period may be adjusted by a predetermined value. For example, the calculated value may be adjusted to be reduced by 50% with respect to a registration point that has passed one month. Note that these values are examples and do not limit the present invention.

  The sorting unit 274 arranges the registration points according to the adjustment value by the adjustment unit 273. Specifically, on the basis of the adjustment value provided from the adjustment unit 273, the rank registration points with small values are arranged. That is, since the adjustment value of the point A is “0” and the adjustment value of the point B is “3”, the point A is arranged higher than the point B in the list. Here, when the adjustment value provided from the adjustment unit 273 is a negative number, it can be handled as “0”.

As in the sort unit 262 of the first embodiment, the sort unit 274 arranges the registration points in descending order of the adjustment value obtained from the adjustment unit 273 when the calculation unit 272 calculates the second difference. When the ratio of 1 is calculated, the registration points are arranged in descending order of the adjustment value obtained from the adjustment unit 273, and when the second ratio is calculated, the registration points are arranged in ascending order of the adjustment value obtained from the adjustment unit 273. Composed.
In addition, when the adjustment value provided from the adjustment unit 273 is the same, the sorting unit 274 arranges the sorting value so that the one with the larger number of set times or the number of arrival times is higher. If the number of times is also the same, the registration points are arranged based on the order of the registration point IDs and the alphabetical order of the point names.

  The list generation unit 275 generates a registration point list so that the registration points arranged by the sorting unit 274 are displayed at the top in the order in which they are arranged. The generated registration spot list is output to the display output unit 14, and the display output unit 14 displays it on the display 14A.

Next, the registration point list display operation of the navigation device 2 configured as described above will be described with reference to FIG.
When the user inputs a destination setting operation for setting a desired facility or point as a destination through the input unit 10, the control unit 31 displays a destination setting menu screen (how to search for the facility or point). FIG. 6) is generated and displayed on the display 14A by the display output unit 14 (step S201).

  When the user selects the registration point search key (Key 1) from the destination setting menu screen (step S203), a registration point list display instruction is output from the input unit 10 to the control unit 31. In response to the instruction, the calculation unit 272 reads the set number of times and the number of arrivals from the registered point data 24, and calculates the difference between the set number of times and the number of arrivals (arrival number−set number of times) for each registered point (step S205). On the other hand, when a search method other than the registered point search is selected from the destination setting menu screen, the facility or the point to be set as the destination is searched for using the selected search method by a known algorithm. The calculation unit 272 provides the adjustment unit 273 with the value result calculated for each registration point.

At this time, when a registration point list display instruction is output from the input unit 10 to the control unit 31, the instruction is received, and the time measuring unit 271 is stored in the current date and time information and count information table obtained from the date and time detection unit 16. Based on the last arrival date and time information, the elapsed days are counted for each registered point (step S207). The time measuring unit 271 provides the adjusted number of elapsed days to the adjusting unit 273.
When the adjustment unit 273 is provided with the calculation result calculated in step S205 from the calculation unit 272 and the elapsed days counted in step S207 from the timing unit 271, the calculation unit 272 corresponds to the elapsed days for each registration point. Is adjusted (step S209). Then, the adjustment unit 273 provides the adjustment value adjusted for each registration point to the sorting unit 274.

The sorting unit 274 arranges the registration points in ascending order according to the adjustment value provided from the adjustment unit 273. The list generation unit 275 generates a registration point list from the registration points arranged by the sorting unit 274 such that the registration point having a small adjustment value is higher (step S211). Then, the list generation unit 275 outputs the generated registration spot list to the display output unit 14, and the display output unit 14 displays the registration spot list on the display 14A (step S213).
Then, by selecting a desired registration point from the displayed registration point list using the input unit 10, the details of the selected registration point can be displayed or the destination can be set.

  Specifically, when the five registered points from point A to point E shown in FIG. 11B are stored in the registered point data 24, the calculation unit 272 calculates the set number of times from the number of arrivals for each registered point. As a result of the calculation, the point A is “0”, the point B is “12”, the point C is “5”, the point D is “4”, and the point E is “−1”. Then, the calculation unit 272 provides these calculation results to the adjustment unit 273. In the same way, when the elapsed time is counted for each registered point by the timing unit 271 and the current date and time is 2013/12/31 12:00, the elapsed time of each registered point is about one month at point A. 1 day, point B is approximately 2 months and 3 days, point C is approximately 21 days, point D is approximately 1 day, and point E is approximately 11 days.

  Then, in consideration of the number of days elapsed by the time measuring unit 271, the adjusting unit 273 adjusts the calculation result, the point A is “0” that is half the calculation result “0”, and the point B is the calculation result “12”. "3" which is halved twice, "5" where the calculation result "5" remains as for the point C, "4" where the calculation result "4" remains as for the point D, and "1" as the calculation result "-1" The adjustment value adjusted to “−1” is obtained (FIG. 14A).

  The adjustment unit 273 provides the adjusted value to the sorting unit 274, and the sorting unit 274 arranges the order of the point E, the point A, the point B, the point D, and the point C in ascending order of the adjustment value. The list generation unit 275 generates a registration point list in the order of the point E, the point A, the point B, the point D, and the point C so that the registration points with a small difference are higher in the list (FIG. 14B). ), And outputs the generated registration point list to the display output unit 14. Then, the display output unit 14 displays the registered spot list on the display 14A. Compared to the case of the first embodiment, it can be seen that the point B has been changed to a higher rank. This is determined because the last arrival date and time of the point B is the oldest and the user may not clearly remember the route to the point B.

  As described above, according to the second embodiment, the navigation device 2 registers the display order of the registration points based on the set number of times set at the destination, the number of arrivals at the registration point, and the final arrival date and time. Since the point list is displayed, if it has not been used for a certain period of time, it is possible to display the registered point list with the optimal display priority by the user by determining that he has forgotten the way he has learned once and adjusting the display order. become.

  Also in the second embodiment, the calculation unit 272 calculates the first difference (number of arrivals−set number of times) and sorts based on the calculation result. However, the present invention is not limited to this. The unit 272 may calculate the second difference (set number−arrival number), the first ratio (set number / arrival number × 100), and the second ratio (arrival number / set number × 100). Good.

  In the embodiment described above, the registration point list display process has been described. However, the destination setting history list is stored by storing the number of times of setting to the destination and the number of times of arrival at the point for each destination setting history. This can also be applied to display.
