BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0021]
First, the configuration of the embodiment of the present invention will be described with reference to FIG.
[0022]
A first embodiment of an information sharing system according to the present invention connects an information provider server 10 of an information provider, a user terminal 20 of a user who uses the provided information, and connects the information provider server 10 and the user terminal 20. And a network 50 including the Internet.
[0023]
The user terminal 20 includes user terminals 20, 21, 22,... Carried by a plurality of users, respectively.
[0024]
The information providing server 10 is constituted by an information processing device such as a workstation server, for example, and as shown in FIG. 1, an information holding mechanism 101 such as a magnetic disk device for storing and holding information to be provided to a user, , A receiving mechanism 103 for receiving the collected information, and a comparing mechanism 104 for comparing information between the received information and the information holding mechanism 101. When the received information is an image such as a photograph, the image processing apparatus includes an image processing mechanism 106 that analyzes the image.
[0025]
The information providing server 10 has a function of receiving information provided by an information supplier (not shown) and transmitting the information to a user of the information.
[0026]
Are used by a user who wants to use the information, and are configured by an information processing device such as a portable information terminal or a mobile phone. As shown in FIG. A transmission mechanism 202 for transmitting information, a display mechanism 203 for displaying received information, a storage mechanism 204 such as a magnetic disk device for storing and holding information, and a comparison for comparing received information with stored information. A mechanism 205, a timing mechanism 206 for transmitting information at specified intervals, a terminal information generating mechanism 207 for generating information to be transmitted by combining the received information and the information of the user terminal 20, and a time information from the GPS satellite 60. And a time position acquisition mechanism 208 for acquiring a position.
[0027]
Further, the user terminal group 300 is formed by gathering according to information types, various matters, and events required by the plurality of user terminals 20. There may be a plurality of user terminal groups 300. In this case, in order to identify the user terminal group 300, a group ID is assigned to the user by the group identification mechanism 105 of the information providing server 10.
[0028]
The user terminals 20, 21, 22... Have a function of receiving various types of information transmitted by the information providing server 10 by operation of the information user, generating information, and displaying the information. Further, it has a function of adding its own information to the received information and newly transmitting information to the information providing server 10 and other user terminals 20.
[0029]
Next, the operation of the present embodiment will be described in detail with reference to FIG. In the description of the present embodiment, it is assumed that the user terminal is composed of two user terminals 20 and 21, but the user terminal is not originally limited to two.
[0030]
The information providing server 10 constantly obtains and maintains the latest information from the outside by the sensor mechanism 30 and the information communication mechanism 40, and accumulates information in the information holding mechanism 101.
[0031]
The information of the information holding mechanism 101 is always transmitted from the transmitting mechanism 102 to the user terminals 20 and 21. The method of transmitting information is the network 50 mainly based on the Internet, but may include methods such as infrared, wireless, optical communication, and wired.
[0032]
The information transmitted from the information providing server 10 is received by the receiving mechanism 201 of the user terminal 20. The information obtained by the receiving mechanism 201 is sent to the comparing mechanism 205. The comparison mechanism 205 acquires the acquired accumulated information from the storage mechanism 204, compares the acquired information with the information acquired from the reception mechanism 201, and determines whether the information is valid information.
[0033]
When the comparison mechanism 205 determines that the information obtained by the receiving mechanism 201 is valid information, the information obtained from the receiving mechanism 201 is stored in the storage mechanism 204 and sent to the display mechanism 203.
[0034]
The information sent from the comparison mechanism 205 is displayed on the display mechanism 203 and notified to the user. If the comparing mechanism 205 determines that the information obtained by the receiving mechanism 201 is invalid (the same information or past information), the data received by the receiving mechanism 201 is discarded, and the data received by the receiving mechanism 201 is discarded by the storage mechanism 204 and the display mechanism 203. No information update or information display instruction is performed.
[0035]
The user terminal 20 senses the state of the terminal by the terminal information generation mechanism 207, generates information unique to the user terminal 20 based on the difference between the information stored in the storage mechanism 204 and the above-described terminal state information, and stores the information. It is stored in the mechanism 204. Such information includes, for example, newly generated information obtained by combining current position information, moving speed information, and the like.
[0036]
Further, the user terminal 20 requests the receiving mechanism 201 or the transmitting mechanism 202 to receive or transmit information at a designated value or at a specific time or at an event interval by the timing mechanism 206. The receiving mechanism 201 and the transmitting mechanism 202 that have received a request for reception or transmission from the timing mechanism 206 store the received information in the storage mechanism 204, obtain the information accumulated from the storage mechanism 204, and transmit the information to the outside. Send information to This information can be provided to another user terminal 21 or the information can be fed back to the information providing server 10.
[0037]
The information providing server 10 receives information feedback from the user terminal 20 through the receiving mechanism 103. The information from the user terminal obtained by the receiving mechanism 103 is sent to the comparing mechanism 104. The comparison mechanism 104 that has obtained the information from the user terminal 20 compares the information with the information held in the information holding mechanism 101 and determines whether the information is valid information. If the information is valid and is update information of the information transmitted by the information providing server 10 itself, the information is updated as new information of the information holding mechanism 101.
[0038]
If the information from the user terminal 20 is not the information transmitted by the information providing server 10 itself, it is determined that the information is transmitted from another information transmitting device, and the information is transmitted to the information communication mechanism 40. Through the information communication mechanism 40, the information is transmitted to the information holding mechanism 40 of the transmission source through the information communication mechanism 40 of another information providing server 10 that is the information transmission source. The information holding mechanism 101 that has been sent from the external terminal and obtained the information from the information communication mechanism 40 calls the comparison mechanism 104, compares the information with the information already held in the information holding mechanism 101, and determines that the information is valid information. If it is determined, the information obtained via the information communication mechanism 40 is updated with respect to the old information of the existing information holding mechanism 101.
[0039]
As described above, by adding the group identification mechanism 105 to the information providing server 10 with respect to the contents described with reference to FIG. 1, a plurality of user terminals 20 can be positioned as a group. By this grouping mechanism, the information provider can supply common information, select and provide effective information specialized for each group, and share information within a user group. The group identification mechanism 105 is added as one of the determination conditions of the comparison mechanism 104, and validity information is determined.
[0040]
The image processing mechanism 106 has contents for analyzing an image such as a photograph received from the user terminal 20 and extracting, for example, the degree of congestion.
[0041]
FIG. 2 shows an overview of this grouping example. The information providing server 10 transmits common information and information specific to each group. The common information is provided commonly to the group A300, the group B310, and the group C320. For example, in the case of information on group A, the information specific to the group is notified to the user terminal 1A301 of group A and the user terminal 2A302 of group A. The common information transmitted from the user terminal 1A of the group A can be shared by the information providing server 10 and each of the groups A300, B310, and C320. If the information transmitted by the user terminal 1A is designated by a group, for example, information limited to the group A, only the group A user terminal 1A301 and the user terminal 2A302 can obtain the information.
[0042]
A specific example of the present invention will be described.
[0043]
In the first embodiment of the present invention, when participating in an amusement park, an exposition hall, a research presentation hall, and the like, a group is formed among users based on desired attractions, event contents, subcommittees, and the like. 3 has the content of exchanging information with each other, and will be described based on the flowchart of FIG.
[0044]
A sensor mechanism 30 is provided at an entrance of a game facility or venue to count, for example, the number of visitors. At an appropriate time, the counted value is reported to the information providing server 10, and the congestion degree of the entrance is measured. Hereinafter, the amusement facilities and venues will be referred to as amusement parks, and attractions, events, and subcommittees will be described as attractions.
[0045]
At the time of entry, the user selects a plurality of attractions that the user desires to use (step A1). At this time, users having the same combination of selected attractions constitute one group. If there are 1 to 10 attractions in the amusement park, for example, if there is a user who wants to use the three attractions, attractions 1, 3 and 5, the users who have selected them form a group. Will be.
[0046]
At the time of entry, the user inputs the identification number of each attraction in the combination of the attraction selected by the user and the e-mail address of the user terminal 10 possessed by the user from the terminal at the entrance (step A2). The input information is transmitted to the information providing server 10 of the amusement park via the information communication mechanism 40.
[0047]
The group identification mechanism 105 of the information providing server 10 obtains a group ID given in advance to a combination of attractions selected by the user, and stores the user's e-mail address based on the group ID. The stored information is stored in the information holding mechanism 101 (Step A3).
[0048]
The information providing server 10 downloads the e-mail address of the information providing server 10 and a program necessary for information exchange between the user terminal 20 and the information providing server 10 by e-mail to the user terminal 20 by wireless or the like. (Step A4). In the user terminal 20, the downloaded program is arranged on the RAM memory.
[0049]
The user enters the amusement park and goes to a reception place of a desired attraction. For example, when the reception place is crowded, the congestion state waiting for reception is photographed by the camera of the user terminal 20, and this image is transmitted to the information providing server 10 by e-mail. At this time, the position and time of the attraction reception location captured by the GPS function of the user terminal 20 are also transmitted (step A5).
[0050]
When the information providing server 10 receives this e-mail by the receiving mechanism 103,
The group ID to which the user belongs is determined based on the e-mail address of the transmitting user of the received e-mail (step A6).
[0051]
The received e-mail information is compared with information belonging to the determined group ID on the information holding mechanism 101 by the comparing mechanism 104 (step A7). At this time, the position to be compared is the position by the GPS function. If an e-mail whose position is close is already stored in the information holding mechanism 101, the received e-mail is determined to be information at the same position. Then, the times at which the information was collected are compared. If the time of the received e-mail is older than the stored time, the e-mail is discarded (step A8). If the electronic mail is newer, the replacement is performed by the information of the electronic mail (step A9). If the position is equal to or more than the predetermined threshold, the e-mail information is newly registered in the information holding mechanism 101 as information of another place (step A10).
[0052]
The information providing server 10 can also process the received e-mail image to check the number of persons on the image, and compare the result with a preset threshold to see the stage of the congestion degree (step A11). .
[0053]
The information providing server 10 accumulates the latest situation of the reception place of each attraction received from the user in this way for each group based on the group ID, and periodically transmits the accumulated image to the sender in the same group ID. Send as e-mail to each user except. At this time, based on the congestion degree of the visitors collected at the entrance and the congestion degree at each attraction, the congestion degree expected at each attraction site may be transmitted together as supplementary information (step A12). ).
[0054]
In the user terminal 20, the timing mechanism 205 refers to the user's received mailbox at regular intervals to check for the presence or absence of the received mail. Upon receiving the e-mail from the information providing server 10 (step A13), the comparing mechanism 205 compares the received information with the received information stored in the storage mechanism 204 (step A14). If there is information close to the position, the information of the storage mechanism 204 is replaced by the newly received e-mail (step A15). Information that is far apart is newly registered (step A16).
[0055]
In this way, after the comparison, the received e-mail is displayed on the display mechanism 203, and the user refers to the congestion degree of the attraction reception place as a photographic image (step A17).
[0056]
As a result, the user can find an attraction with low congestion and can move to the attraction.
[0057]
Next, a second embodiment of the present invention will be described.
[0058]
In the second embodiment, for example, users who enjoy the same hiking course on a day can exchange information about rare things discovered on the hiking course using the user terminal 20 of the mobile phone. 4 will be described.
[0059]
In this case, for example, a computer in a tourism section of a prefectural office or the like having a hiking course is used as the information providing server 10. The homepage of the Internet of the information providing server 10 includes, for example, map information on hiking courses in this prefecture, explanations of the nearest station, required time, sights, resting places, etc., and users who have used this hiking course so far. Impressions etc. are released. The user's impression information is stored in the information holding mechanism 101 of the information providing server 10.
[0060]
The user accesses the homepage using the user terminal 20, and selects a hiking course that he or she wishes to take a short time to walk, for example, tomorrow or on the day. Subsequently, the date and time when the walk is performed on the selected hiking course, the user's name or nickname, the e-mail address of the mobile phone, and the like are registered on the homepage of the information providing server 10 (step B1).
[0061]
In the information providing server 10, upon receiving this registration, the group identification mechanism 105 creates a group ID consisting of several characters based on the hiking course and the date and time designated by the user, and creates a user ID together with the e-mail address of the information providing server 10. The terminal 20 is notified (step B2). At this time, the information providing server 10 may further transmit a program for improving operability related to transmission and acquisition of information in the user terminal 20 to the user terminal 20.
[0062]
Thereby, users who visit the same hiking course on the same day are grouped by the set group ID. This group ID may be kept private or open to the users other than the users constituting the group. In the case of disclosure, for example, when there are a plurality of hiking courses, the group ID set for each can be extracted from the user terminal 20 together with the hiking course name as list information, and the extracted group ID is specified to specify another group. Information can be referred to.
[0063]
The information providing server 10 transmits the list ID by inputting the group ID given by the user from the user terminal 20. The list information includes the names of the users constituting the group or nicknames such as “Hi-chan” and their e-mail addresses. This allows each user to refer to other members of the group to which the user belongs.
[0064]
In this way, it is assumed that there are users A and B who have joined the same group on the hiking course. It is assumed that the user A encounters a scene that he or she wants to teach to other group participants because there is an interesting thing found during the course stroll. For example, when you find a rare alpine plant.
[0065]
The user A extracts the GPS information transmitted from the GPS satellite 60 by the GPS device of the user terminal 20 in order to know the current position and the current time. The retrieved position, time, and the impressions of the user are transmitted to the information providing server 10 as e-mail (step B3). If the user terminal 20 does not have a function of taking out the time from the GPS satellite 60, the time is taken out by the time keeping function of the user terminal 20.
[0066]
The information providing server 10 that has received this information writes the received GPS position information on the map information of the hiking course, and, along with the time information and impressions described in the e-mail of the user A, other users belonging to the same group. B and the like are transmitted by e-mail (step B4). FIG. 5 shows an example of this e-mail.
[0067]
The user B in the same group receives and confirms the transferred information by the user terminal 21 and uses the received information, for example, when the user A has not yet reached the location of the thing discovered on the hiking course. (Step B5).
[0068]
The user B confirms the thing discovered by the user A. For example, in the case of an alpine plant that he knows, the user B adds the e-mail from the user A to the e-mail describing the name of the plant. The information is transmitted from the terminal 21 to the information providing server 10 (step B6).
[0069]
When receiving the e-mail, the information providing server 10 transfers the e-mail to the user A or the like in the same group again (step B7). It should be noted that the user B can also send an e-mail expressing appreciation for having the user terminal 21 teach individual good information only to the user A (step B8). This is because the e-mail addresses of the users having the same group ID are disclosed.
[0070]
Furthermore, it is assumed that the information providing server 10 regularly receives forecast weather information about the area near the hiking course through the information communication mechanism 40. For example, when a shower is expected in the afternoon in the forecast weather information, the information providing server 10 transmits, to the user of the relevant hiking course, information indicating that a shower is expected in the afternoon as common information (step B9). .
[0071]
Also, when an unexpected event occurs, such as when the user of the hiking course encounters a bear, the user terminal 10 notifies the information providing server 10 of the fact together with the position and time information acquired by the GPS function. Also in this case, the notification is sent to all the related users as the common information.
[0072]
Although the utilization aspects of the embodiment of the present invention have been described based on the two examples, it is apparent that the embodiment of the present invention can be applied to various fields other than the two examples. is there. For example, a plurality of mobile terminals, such as automobiles, photograph road congestion conditions and sequentially transmit the photographs to the information providing server 10. The information providing server 10 analyzes the received images and reflects the congestion status of each road on a map. On the contrary, the present invention can be applied to a system for notifying a car. In this case, users who aim at the same destination can be regarded as one group, and road congestion information near the destination can be provided to the cars constituting the group.
[0073]
【The invention's effect】
The first effect is that the latest information on the place is always available, so that it is easy for the receiver to make an accurate situation determination. The reason is that the receiving terminal at the place adds the latest information and feeds it back to the information provider as new information, so that the user terminal that entered the service area is the user just before experiencing the situation Use terminal information.
[0074]
The second effect is that the information can be provided to a wider range of recipients because the user terminal is the information provider even for information at a place outside the range of the information transmitting / receiving terminal of the information provider. It is. For example, information transmitted from the user terminal of the oncoming vehicle in the oncoming traffic network supplies information on the destination of the own vehicle, and provides a means for obtaining effective information on the future traveling direction. In addition, even if the own vehicle is located in an environment where information cannot be directly obtained from the information transmitting / receiving terminal 10, if the oncoming vehicle passes through an effective area, the communication areas of both vehicles overlap, and thus the information is obtained. Can be shared.
[0075]
The third effect is that, even when the information provider provides a service in a wide range, the user terminal itself transfers the information of the information transmission / reception terminal 10, albeit temporarily, to provide virtual information transmission / reception. It functions as the terminal 10. With this effect, if a certain number of user terminals are functioning, even if the number of information transmission / reception terminals 10 to be installed is limited, the same information service becomes possible. A wider range of information can be provided at lower cost.
