Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a message exchange system.

[0002]

2. Description of the Related Art Conventionally, in a navigation device installed in a vehicle such as an automobile, an optimum route from a set departure point to a destination is searched based on road map data and displayed on display means. It is supposed to. In this case, the route is set so that the distance from the departure place to the destination is the shortest, or the route is set so that the required time is the shortest.

[0003] In addition, it is possible to receive traffic congestion information on a road and search and set a route avoiding a traffic congestion section.
A system for transmitting road traffic information to a navigation device is also provided.

For example, in a road traffic information communication system called VICS, information on traffic control systems of police, the Japan Highway Public Corporation, etc. is collected, road traffic information on traffic congestion on the road is created, and this is communicated by communication means. Thus, the data is transmitted to the navigation device. The navigation device that has received the road traffic information searches and sets a route that avoids a congested section based on the road traffic information.

Further, there has been provided an electronic mail transmission / reception system using a navigation device having communication means (see Japanese Patent Application Laid-Open No. 11-108676). In this case, when the navigation device receives the e-mail attached with the position information, the navigation device displays the position specified by the position information with a mark on a map. Then, a route can be searched using the position as a destination. In addition to the mark, the description about the position and the title and contents of the received e-mail are displayed.

Accordingly, an operator such as a driver of a vehicle can
Not only can the route to the destination specified by e-mail be easily searched, but also information on the destination can be grasped in advance.

[0007]

However, in the above-mentioned conventional system, the title, contents, etc. of the e-mail are displayed on the map as they are, so that the operator can instantly grasp the essential points. Was difficult.

That is, if a relatively long sentence such as the title and contents of an e-mail is displayed as it is, attention must be taken for a relatively long time to grasp the points such as the name of the destination and the desired arrival time. Need to be focused. Also, if a long sentence is displayed as it is, the display range becomes wide, and the display of the map becomes invisible.

[0009] By the way, even if the desired time of arrival at the destination is included in the content of the e-mail, if the current position of the vehicle is away from the destination or traffic jams occur, It is impossible to arrive at the destination by the desired arrival time. In this case, since the navigation device searches for a route to the destination in consideration of road traffic information, it is possible to predict an arrival time. Therefore, the operator can know in advance that it is impossible to arrive at the destination by the desired arrival time. However, in the conventional system, the sender of the e-mail cannot know that it is impossible to arrive at the destination by the desired arrival time unless the operator informs. Was.

When the operator contacts the sender of the e-mail, it is necessary to make a call using a portable telephone or to transmit the e-mail using the navigation device. People feel annoying. Especially when the operator is a driver of a vehicle, it is necessary to stop the vehicle, make a telephone call or send an e-mail from a safety point of view, so that not only is it bothersome, but also the arrival time is further delayed. Would.

The present invention solves the problems of the conventional system, extracts keywords such as time from a received e-mail and displays them on a map, and the predicted arrival time is later than the desired arrival time. In this case, the sender of the e-mail is returned to the sender of the e-mail so that the operator can easily and accurately grasp the gist of the received e-mail, It is another object of the present invention to provide a message exchange system capable of grasping necessary information.

FIG. 4 is a second diagram showing the display screen, FIG. 4 is a third diagram showing the display screen of the display means of the information terminal that has received the e-mail according to the present embodiment, and FIG. FIG. 4 is a fourth view showing a display screen of the display means of the information terminal, FIG. 6 is a first view showing a display screen of the display means of the information terminal which has received the reply e-mail according to the present embodiment, and FIG. FIG. 2 is a second diagram showing the display screen of the display means of the information terminal that has received the reply e-mail according to the embodiment, and FIG. 8 is a flowchart showing processing when an e-mail is received according to the present embodiment.

First, an operator B, one of the operators, operates the information terminal 28b and sends an e-mail to the information terminal 28a of the operator A, another operator. In this case, the content of the e-mail is "Let's meet at XX restaurant at 18:00", and location information of XX restaurant is attached.

When the e-mail is transmitted from the information terminal 28b, the e-mail is first received by the transmission / reception means 26 of the message exchange server 11, and subsequently, the time keyword "18: 00 ”is extracted. Here, the time keyword may be “6:00 PM”, “6:00 PM”, “18:00”, or the like. When the content includes a plurality of time keywords, when the time keyword is extracted by the keyword extracting means 25, the message exchange server 11
A time keyword reference database (not shown) is stored in the information providing means 14 in the, and the time keywords in the e-mail are extracted by referring to the contents of the e-mail and the time keywords stored in the time keyword reference database. You may.

In the time keyword reference database, "PM 6:00" as a plurality of time keywords,
“6:00 pm”, “18:00”, “18:00”, etc. are stored.

When a keyword such as "date and time" and "date and time:" is extracted from the e-mail, the keyword extracting means 25 uses a word in a predetermined range following the word, for example, up to the first line feed as a time keyword. You may make it extract. For the time keyword, an optimal time keyword is selected by judging words before and after the time keyword, that is, by judging from the context. Further, when the format of the e-mail includes a column for a time keyword, the time keyword is more reliably extracted.

Here, the keyword extracting means 25
It is desirable that keywords other than the time keyword be extracted from the contents of the e-mail, such as a keyword indicating a place or a facility as a destination, and a keyword such as a telephone number of the facility. In this case, “XX restaurant” is extracted as a keyword indicating a facility as a destination.

Next, the e-mail is transmitted from the transmitting / receiving means 26 to the information terminal 28a. And the information terminal 2
A display screen as shown in FIG. 2 is displayed on the display means 8a. If the format of the e-mail includes a column for a time keyword, a display screen as shown in FIG. 3 is displayed.

When the operator A operates the information terminal 28a to place a pointer, a cursor, or the like on a frame indicating a "position information" button on the display screen as shown in FIG. The pressing of the "location information" button is transmitted to the transmission / reception means 26 of the message exchange server 11. When the display screen is a touch panel, when the operator A touches the frame indicating the “location information” button with a finger or the like, the “location information” button is pressed.

Subsequently, the map creating means 22 of the message exchange server 11 creates a map based on the location information of the XX restaurant. Then, the map is transmitted and received
To the information terminal 28a. Then, the information terminal 2
The display control means 8a causes the display means to display the map, and causes the レ ス ト ラ ン restaurant to be displayed on the map. Further, the name of the OO restaurant and the desired arrival time as a time keyword are displayed as shown in FIG. When the information terminal 28a has a map database, the information terminal 28a may create the map. When a time keyword is extracted from the e-mail text by the keyword extracting means 25, one sentence including the time keyword may be extracted and displayed in a balloon shown in FIG.

Then, the operator A operates the information terminal 28a to display "destination setting" on the display screen as shown in FIG.
Button in the same manner as the "location information" button,
When the button is pressed, the fact that the “destination setting” button is pressed is transmitted to the transmitting / receiving means 26 of the message exchange server 11.

Subsequently, the route search means 24 of the message exchange server 11 searches for a route with the ○ restaurant as a destination. In this case, the route may be searched in consideration of traffic information such as traffic congestion information stored in the traffic information database 21 or the occurrence of traffic congestion may be predicted based on the accumulated statistical information to determine the route. You may search.

Further, the predicted arrival time calculating means calculates a predicted arrival time at which the vehicle will arrive at the destination based on the route. Also in this case, the traffic information database 2
The predicted arrival time may be calculated in consideration of the traffic information such as the traffic information stored in No. 1 or the occurrence of a traffic jam is predicted based on the accumulated statistical information to calculate the predicted arrival time. You may.

The route and the estimated arrival time are transmitted from the transmitting / receiving means 26 to the information terminal 28a. Then, the display control means of the information terminal 28a displays the route and the estimated arrival time on the map on the screen of the display means as shown in FIG. When the information terminal 28a includes a route search unit and an estimated arrival time calculating unit, the information terminal 28a may search for the route and calculate the estimated arrival time.

Further, the time keyword and the estimated arrival time may be output as audio by audio output means such as a speaker (not shown).

As described above, the keyword of the content of the electronic mail is displayed on the display means of the information terminal 28a.
The operator A can grasp the contents of the e-mail instantly without having to concentrate his attention on the display screen for a long time. Also, the destination included in the content of the e-mail and the route to the destination are displayed on the map,
The destination and the route to the destination can be easily and accurately grasped, and the vehicle can reliably arrive at the destination.

Further, since the desired arrival time and the estimated arrival time extracted as the time keywords are displayed, the operator A can predict the situation at the time of arriving at the destination in advance and take appropriate measures. can do. For example, if the estimated time of arrival is significantly earlier than the desired time of arrival, you can make a detour or complete your business, and if the estimated time of arrival is later than the desired time of arrival, you can You can prepare an excuse.

On the other hand, the comparing means of the message exchange server 11 compares the predicted arrival time with the desired arrival time extracted as the time keyword. If the comparison means finds that the predicted arrival time is later than the desired arrival time as the time keyword, the e-mail reply means sends a reply e-mail indicating that the arrival is later than the desired arrival time. create.

The reply electronic mail is attached with the estimated arrival time and the current position.
Further, the information terminal 28a may create the reply e-mail.

When the predicted arrival time is later than the desired arrival time, the display control means of the information terminal 28a changes the display color or adds a mark as shown in FIG. It is desirable to display the estimated arrival time in such a form as to subtract

Then, the reply e-mail is transmitted from the transmitting / receiving means 26 to the information terminal 28b. Then, a display screen as shown in FIG. 6 is displayed on the display means of the information terminal 28b. In this case, like "The arrival is later than expected. The estimated arrival time is 18:10."
The contents of the reply e-mail include the arrival delay and the estimated arrival time.

Then, when the operator B operates the information terminal 28b and presses the "position information" button on the display screen as shown in FIG. It is transmitted to the transmitting / receiving means 26.

Subsequently, the map creating means 22 of the message exchange server 11 creates a map based on the current position of the information terminal 28a attached to the reply e-mail.
Then, the map is transmitted from the transmitting / receiving means 26 to the information terminal 28b. Then, the display control means of the information terminal 28b displays the map on the screen of the display means as shown in FIG. 7, and displays the current position of the information terminal 28a on the map. When the information terminal 28b has a map database, the information terminal 28b may create the map.

When it is determined that the predicted arrival time is later than the desired arrival time as the time keyword, the position of the information terminal 28a at the desired arrival time may be predicted to calculate the predicted position. In this case, if the position information of the predicted position is attached to the reply e-mail, the predicted position can be displayed on the display means of the information terminal 28b.

When it is determined that the predicted arrival time is earlier than the desired arrival time as the time keyword, a plurality of routes are displayed on the display means of the information terminal 28a, and the operator A
May be selectable.

As described above, the fact that the operator A arrives at the destination with a delay, the estimated arrival time of the operator A, and
Since the current position of the information terminal 28a is displayed on the display screen of the display means of the information terminal 28b, the operator B can easily grasp the information and take appropriate measures. For example, if the predicted arrival time of the operator A is much later than the desired arrival time, the operator B can take a side trip or complete a business on the way.

The e-mail reply means may always generate a reply e-mail, not only when it is found that the predicted arrival time is later than the desired arrival time as the time keyword. For example, a reply e-mail may be created and transmitted when the destination is set. In this case, if the predicted arrival time of the operator A, the current position, and the like are attached to the reply e-mail, the operator B always grasps the status of the predicted arrival time, the current position, and the like of the operator A. be able to.

The time at which the reply e-mail was returned may be attached so that the operator B can be notified when the operator A has left.

Further, the arrival time calculating means may update the estimated arrival time at regular intervals. In other words, even if the estimated arrival time calculated first is earlier than the time keyword, it may be delayed due to traffic congestion or the like. In this case, if the arrival time is updated at regular intervals, when the updated estimated arrival time is later than the time keyword, a reply e-mail indicating that the user will arrive late must be created and transmitted. Can be. for that reason,
At an appropriate timing when it is determined that the arrival is delayed, a reply e-mail indicating that the arrival is delayed can be transmitted.

For example, when the operator A sets the destination based on the position information attached to the e-mail from the operator B, the predicted arrival time is calculated as 17:45, while the time keyword is Assume 18:00. Thereafter, it is assumed that the vehicle of the operator A is caught in a traffic jam on the way. Then, after a lapse of a predetermined time from the first calculation of the predicted arrival time, the arrival time calculating means calculates the predicted arrival time again, that is, updates the predicted arrival time. If the updated predicted arrival time is 18:10, the comparing means determines that the predicted arrival time is later than the desired arrival time as the time keyword. As a result, the e-mail reply means creates and sends a reply e-mail indicating that it arrives late.

If the reply e-mail is transmitted every time the predicted arrival time is updated, the operator B who receives the reply e-mail feels annoying. Therefore, the frequency at which the predicted arrival time is updated may be appropriately set by the operator A (for example, every 15 minutes). Also,
Update the expected arrival time frequently (for example, every 5 minutes)
On the other hand, the frequency of transmission of the reply e-mail may be reduced (for example, transmitted once every three times the estimated arrival time is updated). Further, the reply e-mail may be transmitted only when the difference between the updated estimated arrival time and the previously calculated estimated arrival time is equal to or longer than a predetermined time (for example, 10 minutes or longer).

In this embodiment, an example of the desired date of arrival as a time keyword, that is, an example in which the desired date of arrival is the transmission date or the reception date of the e-mail, has been described. The date may be different from the transmission date or the reception date of the electronic mail.

For example, if the content of the e-mail from operator B received on Wednesday is "Let's meet at レ ス ト ラ ン restaurant at 18:00 on Saturday," operator A sends the electronic mail to information terminal 28a. Mail can be stored. Then, on Saturday, which is the desired arrival date, the information terminal 28a automatically displays the contents of the e-mail on the display means and performs the above-described operation.

The desired arrival date may be automatically extracted by the keyword extracting means 25 from the contents of the e-mail. However, the format of the e-mail is added to the column for the time keyword and the format for the date keyword. , The desired arrival date is more reliably extracted. Further, the operator A may input the desired arrival date.

As described above, in the present embodiment, when an e-mail attached with location information of a destination is received,
The keyword, the destination, and the route to the destination included in the content of the e-mail are displayed on the map displayed on the display means of the information terminal 28a.

Therefore, the operator A of the information terminal 28a can instantly grasp the contents of the e-mail without having to concentrate his attention on the screen of the display means for a long time. And easily get to the destination,
In addition, it is possible to accurately grasp, and it is possible to reliably arrive at the destination.

Further, the desired arrival time and the predicted arrival time extracted as the time keywords are displayed, so that the operator A can predict the situation at the time of arrival at the destination in advance, and take appropriate measures. can do.

Further, when the predicted arrival time is later than the desired arrival time, a reply e-mail is created, and a reply is sent to the information terminal 28b that sent the e-mail. Therefore, the operator B of the information terminal 28b is notified that the operator A arrives at the destination with a delay,
The predicted arrival time of the operator A and the current position of the information terminal 28a can be easily grasped, and appropriate measures can be taken.

Next, the flowchart will be described. Step S1 The e-mail transmitted from the information terminal 28b is received by the transmission / reception means 26 of the message exchange server 11. Step S2: It is determined whether or not the location information of the destination is attached to the e-mail. If it is attached, the process proceeds to step S3, and if it is not attached, the process ends. Step S3: The keyword extracting means 25 extracts a time keyword from the contents of the electronic mail. Step S4 The operator A operates the information terminal 28a,
