It comprises a transmission unit 10 for transmitting to the center.

For example, when the information providing system for a mobile object is applied to an exhibition, the mobile objects 2-1 to 2-n represent portable terminals of participants in the exhibition, and the information providing terminal 3-
1-3 to n represent terminals installed in each exhibition booth of the exhibition. The exhibitor is notified in advance that the target participant is nearby and sends a message to the target participant, prompting the target participant to visit each individual. Can send messages.

Next, an example of mobile information stored in the mobile information database 4 of the information center 1 will be described.
The information in the mobile unit information database 4 is registered in advance manually or the like, or when the information is stored in the information center 1 by the mobile unit.
And information updated in advance may be updated with information obtained by the mobile unit. In addition, new mobile object information may be created when storing the collected mobile object information.

Table 1 shows an example of mobile unit information and a method of registering the mobile unit information. The only moving object information that the moving object knows is the position,
The information collection and distribution center knows the visit history by setting an information provider corresponding to the position in advance. Other mobile object information is registered in the information center in advance.

[0052]

[Table 1]

Table 2 shows another example of the mobile unit information and a method of collecting the mobile unit information. Unlike “Table 1,” the interest is grasped and transmitted by the mobile after the pre-registration. As a result, even if the interest changes while the moving object is moving, the information center can collect the changing interest. "Table 3" shows another example of the mobile object information and the collection method. In this case, the mobile unit grasps all mobile unit information.

[0054]

[Table 2]

[0055]

[Table 3]

The position of the moving object is determined by a notebook computer or PDA.
Can be grasped by IrDA attached to. In this case, the location of the information provider or any location
A DA device is installed, and IrD
A device is specified. By setting the position coordinates corresponding to the specified IrDA device, the position of the moving object can be known.

When the information provider corresponding to the position is set, the visit location can be known. In addition, PH
The position can also be grasped by known position grasping means such as S and GPS. The interest of the moving body may be selected from a list of information providers of interest, or the information provider is classified by field, and may select a field of interest from the field.

When interest is represented by a keyword, the degree of interest can be quantified by using keyword matching. For example, when the keyword is as shown in “Table 4”, the information provider 1
Here is an example in which a keyword matching with is selected.

[0059]

[Table 4]

If the selected keyword is 1 and the others are 0, the next vector can be set. v1 = (110000) Also, an example of a vector representing the content of the information provider 2 is shown.
In this example, the number of the keyword representing the content of the information provider is increased according to the degree of importance. v1 = (0300101)

As described above, a vector representing the content of the information provider is prepared for each information provider. Next, an example in which the user 1 of the moving object selects a keyword that is of interest will be described.
If the keyword of interest is selected as 1 and the others are selected as 0, the next vector is set. u1 = (1100100)

An example in which a keyword indicating the interest of the user 2 is selected will be described. In this example, the number that is more interesting is set to be larger. u2 = (0210002)

As described above, by selecting a keyword, the user can create a vector representing the interest of the user. Here, if the degree of interest is represented by a cosine value of a vector, the interest of user 1 to information provider 1 is u1 · v1 / | u1
|| v1 | = 0.67, and the interest of the user 1 with respect to the information provider 2 is u1 · v2 / | u1 || v2 | = 0.70. The interest of the user 2 with respect to the information provider 1 is u2 · v1 / ｜ u2 ｜｜ v1
| = 0.58, and the interest of the user 2 with respect to the information provider 2 is u2 · v2 / | u2 || v2 | = 0.80.

As described above, the degree of the user's interest in each of the locations between 0 and 1 can be determined. It is assumed that the larger the numerical value is, the more the user is interested. The user's interest can be extracted by determining that the user is more than the lower limit. Further, it is possible to determine that the top n objects having the degree of interest are interested. In addition, it is possible to determine that the number of objects that are equal to or more than the lower limit value and the maximum number is n is interesting.

Table 5 shows an example of the necessary conditions on the information providing side. Thus, different criteria can be set for each of the information providers A and B. Here, when a keyword is used for interest, it is possible to narrow down moving objects of higher interest by designating that the degree of interest is a certain numerical value or more.

[0066]

[Table 5]

Table 6 shows an example of necessary conditions and priorities. Thus, a plurality of necessary conditions can be set. In addition, a priority can be set for each necessary condition. Targets can be narrowed down by increasing attribute conditions.

[0068]

[Table 6]

FIG. 2 is a flowchart showing an example of the operation of the information collection and distribution center. In the figure, the display of S-1 to S-8 indicates the steps of the process, and corresponds to the description in the following description. This is the same in each of the following descriptions. First, one information providing terminal is selected (S-1), then one mobile body is selected (S-2), and the condition is determined (S-
3).

When the determination is completed for all the moving objects (S
-4), if there is mobile information to be transmitted (S-
5), and deliver to the corresponding information providing terminal (S-6). Otherwise, it is not distributed (S-7). The determination is performed for all the information providing terminals (S-8).

FIG. 3 is a flow chart showing an example of the condition determination operation in the information center. First, one necessary condition of the information providing terminal is selected (S-1). If the condition is not met (S-2), it is not considered as a transmission candidate (S-3). If the condition is met, priority (S-4) and expiration date (S- 5), the number of valid times (S-6) is added to make it a transmission candidate (S-7).

Then, condition determination is performed until all conditions are determined (S-8). When all the determinations are completed, sorting is performed, and it is determined that the uppermost number is transmitted to the upper limit number (S-9). At the time of sorting, if interest is represented by numerical values by keyword matching, sorting can be performed using the degree of interest for each priority of each necessary condition. On the information providing terminal, the mobile body information that can be transmitted is displayed.

In the condition determination in FIG. 3, when the condition includes a position condition and the position condition is within a certain distance from the information providing side, it is determined not only that the position is within a certain distance but also that the next visit is made. In some cases, it is determined whether the expected degree is high. The degree is assumed to be a visit expectation degree.

An example of the expected visit degree will be described with reference to FIG. As shown in FIG. 4A, it is assumed that the closer the moving body is to the information providing side, the higher the predicted visit degree becomes. The degree of closeness is defined as the degree of closeness. Specifically, the fixed distance for distance determination is d
_{In the case of a} , where the position on the information providing side is represented by a vector IP _i and the current position is represented by a vector P ₀ , the degree of proximity can be represented as, for example, “Formula 1”.

[0075]

(Equation 1)

This degree of approach ranges from 0 to 1. In addition, as shown in FIG. 4B, even if the distance is the same from the information provider, there are cases where the information provider is approaching the information provider depending on the relationship with the previous position, and cases where it is distant from the information provider. There is also. Can be regarded as being in the middle of moving to the information provider, but it can be said that the current position has once passed the information provider side.

For this reason, it is assumed that the expected visit degree is higher in the example. The degree to which the current position can be said to be in the middle of moving to the information provider is defined as the degree of movement. Specifically, for example, it is assumed that the hatched portion in FIG. Here, it is assumed that the distance is shorter than the previous position and that the moving distance from the previous position to the current position is shorter than the distance between the previous position and the information provider.

At this time, the condition during the movement is “Equation 2”.
It is represented as

[0079]

(Equation 2)

The degree of movement is from the previous position to the current position. It represents how far away from the travel route. That is, the cosine value of the vector P ₋₁ −IP _i and the vector P ₀ −IP _i is determined as the degree of movement. The degree of this movement is from 0 to 1
Range. Further, it can be said that, depending on whether or not the next place that the mobile unit visits after visiting the information provider is centered on a location that is closer to the previous place or not, even if it is located at the same position, the degree of the visit deviation changes.

For this reason, the closer the distance to the next visited site once visited, the higher the degree of approach. Specifically, for example, of the movements from the information provider to the information provider so far, the number obtained by dividing the number of times within da of the distance determination by the number of movements is set as the proximity mobility. The proximity mobility is a value from 0 to 1. Assuming that the degree of approach is f _l , the degree of movement is f ₂ , and the degree of proximity movement is f ₃ , the expected degree of visit is f ₀ , which can be expressed as “Equation 3”.

[0082]

(Equation 3)

[0083] In this case, W _i represents the weight. The weight can be set appropriately. Unless otherwise specified, all are set to 1. FIG. 5 is a flowchart showing an example of a method of calculating the expected visit degree in the condition determination. First, to get the current position of the mobile (S-1), the distance between the information provider checks is within d _a. If further than d _a can, visit the expected degree of not calculated. If within d _a, we obtain the access degree from the information provider's position (S-3).

Thereafter, in the case of the previously described hatched portion in FIG. 4C, the degree of halfway through the visit is obtained using the previous position (S-5). Otherwise, the halfway of the visit is set to 0 (S-6). Moreover, obtains a number of movements from the movement history for past information provider (S-7), the distance among them is seeking count is within d _a (S-8),
The proximity mobility is obtained (S-9). Then, the degree of expected visit is calculated using them (S-10).

In the case of the sorting shown in FIG. 3, when the interest is expressed by a numerical value by keyword matching or when the degree of expected visit is obtained, the sorting is performed from the one with the highest value by using them. At the time of sorting, only the degree of expected visit, only the degree of interest, or both may be used.

In the case where both the expected visit degree and the degree of interest are used, it is assumed that the degree of interest is fv. The numerical value serving as an index for performing sorting is, for example, W _f0 · f ₀ +
W _fp · f _p . Here, W _f0 · f
Can be expressed as ₀ + W _fp · f _p. Here, W _f0 ,
W _fp represents a weight. All 1 unless otherwise specified
And

FIG. 6 is a flowchart showing an example of the operation of the information providing terminal. This example shows a case where a person operating the terminal manually selects a transmission target from information displayed on the information providing terminal. First, reset the timer (S-
1) Check whether information is transmitted (S-2),
If it has been sent, it is added to the display list (S-3). Otherwise, a display list update operation is performed (S-
4). Thereafter, a display is made (S-5), and if no information is selected for a certain period of time, the display returns (S-6), and
-7).

If selected, a transmission message is created (S-8). If there is a transmission command (S-9), the expiration date is checked (S-10). Displays that effect (S-11). If the expiration date has not expired, it is checked whether it is within the validity interval (S-12), and if it is within the validity interval, a validity condition for the moving object is added (S-13). The message is transmitted to the corresponding mobile unit (S-14).

FIG. 7 is a flowchart showing an example of the operation of the information providing terminal. This example shows a case where information is automatically transmitted from information displayed on the information providing terminal. First, it is checked whether information has been transmitted (S-1), and if it has been transmitted, it is added to the display list (S-2). If not, a display list update operation is performed (S-3).

Thereafter, the message is displayed (S-4), one piece of display information is selected (S-5), and a message is automatically created (S- 4).
6) Check the expiration date (S-7). If the expiration date has expired, do not transmit. If the expiration date has not expired, it is checked whether it is within the validity interval (S-8), and if it is within the validity interval, a validity condition is added (S-9) and transmitted to the corresponding mobile unit (S-8). S-10). These are performed for all display information (S-11).

FIG. 8 is a flowchart showing an example of the display list updating operation. First, one piece of information is selected (S-1), the expiration date is checked (S-2), and when the expiration date has expired, it is deleted from the display list (S-3). If the expiration date has not expired, the number of valid times is checked (S-4).
If the number of valid times has been reached, it is deleted from the display list. It is checked whether or not all information has been selected (S-5). If all the information has not been selected, the operation from (S-1) is repeated.

Table 7 shows an example of the created message. These are messages corresponding to the four conditions in “Table 6” described above. The message is text,
It is composed of video, image, sound, etc. The message format can be changed for each priority. Also, the content of the message can be changed for each transmission target. In the figure,
The underlined portion is a portion changed for each transmission target.

[0093]

[Table 7]

FIG. 9 is a flowchart showing an example of the operation of the moving body. First, a timer is set (S-1), and it is checked whether a message has arrived (S-2). If a message has not arrived, after a certain period of time (S-
3) Check the arrival of the message again. If a message has arrived, a display schedule is created (S-
4). One message is selected according to the display schedule (S-5).

The validity condition is checked (S-6). If the validity condition is not satisfied, no display is made. If it is suitable for the valid condition, it is displayed (S-7). In the case of the last message of the schedule, the arrival of the message is waited again. It is determined whether the message is the last message (S-8). If not, it is determined whether a new message has arrived (S-9). Follow the schedule. If so, recreate the schedule.

FIG. 10 is a flow chart showing an example of a schedule creation operation in a mobile unit. In this example, the first message is displayed t seconds after the current time, and then the message is displayed at intervals of t _i seconds. Then, the stored messages are prioritized (S
-1). Select from the messages with higher priority (S
-2), using the validity condition added to the message, it is checked whether the message is valid t seconds after the current time (S-).
3).

(S-4) If it is not valid, it is checked whether there are any remaining messages (S-5), and the process is repeated as long as there are remaining messages. When there are no more messages remaining, the schedule creation ends. If it is valid, it is added to the schedule (S-6). If there are no remaining messages at the end, if there is remaining message (S-7), and _{tr = t + t i (S} -8) priority by selecting the higher of the message (S-9), Further, it is checked whether it is valid after tr = t + t _i seconds (S-10).

If the message is not valid, the remaining messages are checked (S-11), and the process is repeated as long as there are any remaining messages. If there are no remaining messages, the creation of the schedule ends. If it is valid (S-12), it is added to the schedule (S-13). Further, the remaining messages are checked (S-14), and if there are any remaining messages, the operation is replaced with t = tr (S-15), and the above operation for adding to the schedule is repeated. If there are no remaining messages, the process ends.

Here, as a method of setting the priority, there is a method of setting the priority using the priority given to the message by the information providing side. In this method, the information desired by the mobile object is not always prioritized. Therefore, by giving priority to the information provider's message with a high degree of interest that is numerically assigned by keyword matching,
There is also a method of assigning priorities to those with high interest in moving objects. Further, the validity condition given by the information providing side may include a condition that the position of the moving object is within a certain range, a condition that the transition to a certain time is not valid, and the like.

[0100]

As described above, according to the present invention, the following effects can be obtained. (1) The information center transmits the mobile unit required by the information providing side to the information providing terminal using the mobile unit information and the necessary conditions of the information providing side, and the information providing terminal transmits the mobile unit to which the information has been sent.
