2. Description of the Related Art Conventionally, a GPS type car navigation, a position recognizing terminal using a PHS base station, a mobile phone with GPS, etc. have been developed as a position recognizing terminal.

[0003]

In the conventional position recognition terminal, the position recognized by the GPS or the like is hardly corrected. Even if it is being done, it is only necessary to correct it if the position recognition terminal should accurately recognize it, such as keeping the track of the car from the road on the map in the car navigation device. The method was also to fix unrealistic situations such as preventing cars from passing through buildings on the map compared to roads on the map.

[0004]

The position recognition terminal according to the present invention has a first feature that the position is manually corrected from the recognized position.
Secondly, in addition to the first feature, that the position to be corrected is far beyond the error range of the terminal, thirdly, in addition to the first or second feature, the display map Moving the current position without moving the train, fourthly, in addition to any one of the first to third characteristics, grasping the boarding position of the train, fifth, first to fourth In addition to any one of the features described above, the guide information at the destination station is changed according to the boarding position of the train. In addition to displaying any one of the first to sixth characteristics, displaying the supplementary service information in the eighth and any one of the first to seventh In addition to the features described above, in addition to the ninth feature, in addition to the eighth feature, the communication feature described above. Characterized in that it is a wireless communication.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the position recognition terminal of the present invention,
In the case where the first feature of manually correcting the position from the recognized position is provided, the current position automatically recognized by recognizing the GPS or the communication radio station, etc. is manually moved according to the purpose of the position recognition. To correct. The correction is performed by a method such as moving the cursor indicating the current position on the map displayed by operating a button or lever from the automatically recognized position. Second
In addition to the first feature, in the case where the position to be corrected has a distant feature that exceeds the error range of the terminal, the range of the automatic recognition method or the position recognition error predicted by the recognition environment is exceeded. The current position recognition is moved to a position beyond the range without being obsessed. Thirdly, in addition to the first or second feature, when a feature for moving the current position without moving the displayed map is provided, when the position recognized as the current position is, for example, the center of the screen, When the current position is moved to the upper right, the cursor position indicating the current position is moved to the upper right and the map is fixedly displayed as it is.
As a result, the position recognized by the position recognition terminal is displayed as it is in the center of the screen, and it is possible to instantly grasp how much the correction has been performed manually. Further, the actual current position may be closer to the automatically recognized position than to the manually shifted position. In this case, we want to keep the first automatic recognition position at the center from the viewpoint that we are located at the center of the map and grasp all directions. Fourth, in addition to any one of the first to third characteristics, when grasping the boarding position of the train, the running condition of the train and the number of trains in operation (8-car train, 10-car train, etc.), etc. Understand which position you are currently on the train from the characteristics of and the positional relationship with the stopping platform.
This grasp is a relative position on the train, and is a position that is always moving (during running) from the ground reference point but stopped on the train. Know this position.
Fifth, in addition to any one of the first to fourth features, when changing the guidance information at the target station according to the boarding position of the train, the stairs or ticket gates that should be used depending on the position at which you get off at the target station May be different. Optimal guidance will be provided based on detailed information about the station and around the station. For this optimal guidance, prepare information based on the time of day (lasheu etc.) as a database. For example, at a station that is the nearest station to a school, a specific ticket gate may be very crowded at a specific time immediately before the opening time. Careful attention should be given to such information, such as guidance to avoid it. Sixth, in addition to any one of the first to fifth features,
When the tenant information of the building is displayed as one group together with the features, comments are displayed as the group regarding the types and features of the tenants. When searching for a restaurant, you may want to roughly search. In the case where one of 20 tenants is a tenant group and 30 of 30 tenants is a restaurant group, the former tenant group is generally out of interest as a tenant group. is there. In this way, grasp as a group and search quickly. Seventh, in addition to any one of the first to sixth features, if the feature is to display supplementary service information, search or route guidance when interested in a specific supplementary service It is reflected in and highlighted. Eighth, in addition to any one of the first to seventh features, in the case of having a feature having a communication function, one using wireless communication such as a mobile phone, PHS, taxi radio, or wireless LAN, and Some use wired communication such as public telephones and LANs. Information is exchanged by communicating the recognized position information and / or the corrected position information. Ninth, in addition to the eighth feature, when the communication function has a feature of wireless communication, wireless communication can be performed even when the position recognition terminal moves or changes its position frequently. I do.

[Embodiment] Embodiment 1 of the present invention will be described. Fig. 1 shows a situation in which, when a private car traveling on a highway breaks down, the passenger recognizes his / her position using a GPS-equipped mobile phone and reports the position information to the road service (automobile repair). It is a schematic diagram for explaining. In FIG. 1, the failed vehicle position is the position of the black circle labeled recognition position 1. Since this mobile phone has an error of a radius of 5 meters, the actually recognized position is somewhere in the large circle surrounded by the error range 2. The failure position of this automobile is the position immediately before the branch lane which is the approach road from the general road. This position will be described in detail. A broken-down private vehicle is on the lane of the driving lane 100. The traveling direction of the lane is represented by the direction of the arrow labeled traveling direction 101. The opposite lane 102 is arranged as shown in the figure, and the branch lane 103 for approaching from the general road is connected to the preceding lane at a position 2 meters in front of the faulty private vehicle. When comparing the error range with the structure of a highway, various errors may occur. One is when it is recognized that the vehicle is in the opposite lane as indicated by the wrong lane misrecognition position 104. Another misconception is when it is recognized that the vehicle is on the branch lane 103. This case is shown in FIG. 1 as another lane misrecognition position 105. In the case of a wrong lane misrecognized position, it is recognized that the vehicle is on a completely different road from the position where the failed private vehicle exists. Road service enters this branch lane from a general road and searches for a broken-down private car, but it is expected that it will not be found. On the other hand, even if you mistakenly recognize that you are in the opposite lane, rescue of road service will be delayed. Since there is a median strip 106 on the highway, the road service may not be found even when searching for a broken-down private car while traveling in the opposite lane. Takes a lot of work such as once getting off to a general vehicle and turning, or going to the break of the median strip and turning back. Therefore, in this embodiment, G
The PS mobile phone carrier manually corrects his / her recognized position. The corrected position is depicted in FIG. 1 as manual correction position 3. This correction position will be described in detail. Since the GPS mobile phone carrier carries out the correction for the purpose of notifying the road service of his / her position, the position indicated as the manual correction position 3 in FIG. 1, that is, the position on the traveling lane where he / she is, is erroneously recognized as the opposite lane. Set it at a position slightly outside the lane so that it will not be misaligned, and at a position shifted toward the front of the confluence so that it will not be mistaken for a branch lane. This means that the vehicle was set at a position about 7 meters before the actual position on the same lane. In this way, even if the position of itself is displaced from the actual position, if that is more suitable for the purpose, the position is displaced. With the position recognition terminal of the present invention, it is possible to shift from the actual recognition position to a range exceeding the error range as in this example.

A second embodiment of the present invention will be described. This is an example of easily specifying a precise destination. FIG. 2 shows the first screen displayed when "Tokyo Station" is designated by the station name when using the destination guidance service on the position recognition terminal. The circle in FIG. 3 (destination details 108) is the place where you want to actually go, but as a way to get to this place, you want to take a train to Tokyo Station and then walk to the location where you can go to the destination details. In this case, the destination details 108 as a new point with the Tokyo station aligned with the center line 4 on the map shown in FIG.
Is designated (FIG. 3). This operation selects a new point from the menu of the mobile phone with GPS (position recognition terminal),
Destination details are selected from the sub-menu, and after the selection, the cursor button is operated to set the destination details at the position shown in FIG. In the new point menu, there is a sub-menu called "Stop-in Place" that specifies the stop-over place in the route. By this designation, the recommended route of the route from the current point to the Tokyo station by train is designated. At a station with a large site and many access lines such as Tokyo Station, the recommended route (train used) may differ depending on the location of the destination details. For example, the subway Marunouchi Line also runs into Tokyo Station, but if you specify the Yaesu Exit, after getting off the Marunouchi Line,
You have to cross Tokyo Station and walk to the other side. It is a route that cannot be recommended because it is the Yaesu Exit. If you consider it in more detail, the line that sets up the platform from the Yaesu exit of Tokyo station can reach the destination details in the shortest time after getting off at Tokyo station.
If the optimum recommended course is selected from another perspective, the following consideration is also necessary. One of the recommended courses when going from Sangenjaya to the Yurakucho station of the Yaesu exit of Tokyo station is one of the recommended courses, from Sangenjaya station via Shibuya station to Nagatamachi station, take the first train as the second train At Nagatamachi station, transfer to the Yurakucho line to go to Yurakucho station, where there is a third train from Yurakucho station on the JR line to Tokyo station. In this course, the first, second, and third trains are important. Considering the transfer at Nagatamachi station, it is convenient to take the first car in the direction of travel at Sangenjaya station. At Nagatamachi Station, you first arrive at the last side of the Yurakucho Line in the direction of travel, but if you board at that position, it will be inconvenient to transfer at Yurakucho Station. I want to get on at the beginning in the direction of travel. The third train arrives at the top position in the direction of travel, but a convenient position at Tokyo Station is at the back of the direction of travel. In the course navigation from Sangenjaya Station to the highway bus terminal, detailed instructions are also given at each transfer station regarding this transfer vehicle according to the destination details. If the next train arrives relatively quickly, we recommend that you walk at the platform at the alighting station without proceeding from end to end. At the same time, the best course for destination details is presented.

A third embodiment of the present invention will be described. Figure 4
I drew a diagram for explanation. It is an example in which the timetable of the bus to be boarded is displayed. The display screen of the mobile phone with GPS is drawn in FIG. When the cursor 6 is placed on the bus stop 5 on the map, the bus route map 7 and the timetable 8 are displayed in the form of a dotted line and a table, respectively, as shown in the figure. The position of the GPS mobile phone at this point is the intersection of the center lines (current position 9). You can get the information about the bus stop just by moving the cursor on the screen of the mobile phone. By default, the timetable displayed here displays the schedule for nine buses from the present time. This setting can be changed. The displayed timetable is corrected and displayed from the original timetable when the actual bus operation status, that is, when the bus is delayed due to traffic congestion or when the bus is operated earlier than the scheduled timetable.

A fourth embodiment of the present invention will be described. GPS
This is an example in which the orientation of the mobile phone is freely changed and used. Normally, as shown in FIG. 4, even if the screen is displayed as a portrait screen, it may be desired to display the screen in a landscape orientation depending on the screen currently desired to be viewed. In this case, it is possible to change and display the display azimuth reference. In FIG. 5, the orientation of FIG. 4 is changed by 90 degrees. As a result, in addition to the bus stop 5 of the bus to be boarded, the disembarkation stop 10 can be displayed on the same screen. There is another similar example for the display screen. This is the case where the disembarkation stop is farther to the right than in FIG. In this case, the vertical center line 4 dividing the screen into the left and right at the center of the screen has a function of separating the left and right maps and winding them up. This will be described in detail with reference to FIG. In FIG. 5, the left half is fixed because the stop to be boarded is displayed. For the right half, the latter stop I'm going to explain here is off to the right of the screen. (Although it is displayed in FIG. 5, it is displayed as it is because the illustration of Example 4 is diverted. After selecting the right screen winding menu from the mobile phone menu, the cursor is moved to the right screen. Move the cursor up and slide the cursor from right to left within that range, and the right screen of the map will be rolled up to the right with the left screen and right screen discontinuous at the center line. In this way, you can see the disembarkation stop that was out of place.In this way, you can effectively use the narrow screen to display the actual stop and the enlarged map near the disembarkation stop at the same time.

A fifth embodiment of the present invention will be described. This is an example of predicting the disembarkation position at the target station while getting on the train and providing home guidance. In FIG. 6, the carrier carrying the GPS mobile phone is currently at position 9 (current position 9). This vehicle is riding on the second vehicle 12 with the leading vehicle 11 at the top. The train is exactly the destination station platform 1
I'm about to arrive at 3. The GPS mobile phone has a function of determining which train of the train it is on the train from the stop position at each station that has passed through before reaching the destination station. By accurately grasping the position of the platform at each station, the position where the GPS mobile phone is stopped for one minute or more is recognized as the position where the train is stopped, and the boarding vehicle is calculated. In this way, since the boarding vehicle can be grasped in advance, it is possible to accurately perform the guidance after getting off at the target station platform. In FIG. 6, a route through the nearest upstairs 14 and through the ticket gate 15 on the upper floor is displayed as a guide line 16. It should be noted that this display screen is designed so that even a floor with a ticket gate raised from the home is displayed on the same screen so that a guide line is simply drawn. This map is designed to make it easier to see by erasing the picture of the home below when a person carrying a GPS mobile phone climbs up to the floor with the ticket gate.

A sixth embodiment of the present invention will be described without using the drawings. It is an example of a restaurant building. Get off at the station and operate a mobile device with GPS for the purpose of finding a good restaurant for dinner. On the display screen, in addition to individual restaurants being displayed, restaurant buildings (tenant buildings with names such as Ajino famous shopping streets) are displayed as a group of restaurants. This restaurant group is, for example, all restaurants from the basement of the building to the 7th floor above the ground, so it is difficult to display it on a flat map. Therefore, it is displayed as a restaurant group to show the characteristics of the group. For example, "Many karaoke snacks", "Many taverns",
"There are many restaurants for families," for example. When the mobile device carrier clicks on the group of interest, information about the building is displayed in detail.

A seventh embodiment of the present invention will be described without using the drawings. This is an example similar to the sixth embodiment, but if conditions such as intention to use a credit card are attached in advance, only applicable restaurants are displayed. In the previous group, 3 out of 10 restaurants will accept credit cards as well.

An eighth embodiment of the present invention will be described without using the drawings. This is an example similar to the seventh embodiment, but is an example of displaying a privilege when a credit card is used and a privilege such as a discount of taxi fee after finishing a meal at a restaurant. The total service you want, that is,
In this example, information about related expenses such as taxi fare as well as restaurant services and benefits is displayed.

[0014]

When the position recognition terminal of the present invention is used, the purpose can be surely achieved regardless of the recognition accuracy of the position recognition terminal. Furthermore, a simulation of what happens if a bus is used to determine his / her future behavior can be virtually performed by operating the position recognition terminal without actually going to the bus stop.
