The invention described in Cooperative Work, Amsterdam, September 1991) specifies the location information of the terminal device, estimates what kind of activity was being performed there, and automatically sends a diary. To detect the position of the user and leave it as a record.

In recent years, with the development of computers and networks, it has become possible to easily obtain information anywhere in the world. However, the fact that information is easily obtained often hinders the intention of actually going to the place and putting himself in a similar environment. In other words, the convenience of easily obtaining information is
On the contrary, it can be seen that it hinders the opportunity to obtain various experiences. From this point of view, the information registration and search device as described above pursues the convenience of use of the registered information, and the registered information is obtained only when the user is placed in the physical environment where the information is actually registered. However, such a use form has hindered the motivation to actually go to the place.

[0006] In view of such circumstances, it is possible to motivate the user to try to put himself in the physical environment in which the information is actually registered. Devices have been developed that can provide the opportunity to obtain such various experiences.

For example, in the invention described in Japanese Patent Application No. 2000-188838 and the invention described in Japanese Patent Application No. 2000-192732, information such as memos and photographs is registered together with information indicating an environment at the time of registration. There are provided an information registration device for searching for information and an information search device for searching for information registered in this way.For example, an individual's thoughts and impressions in a specific environment are associated with the environment. There is realized an apparatus or the like which can record and register the information, and later can retrieve the registered information only when actually placed in the environment.

In the invention described in Japanese Patent Application Laid-Open No. H10-185609, a portable information device detects its own position using a satellite, searches local information from the detected own position, and selectively outputs it. That is being done. Also,
In the invention described in JP-A-9-113599,
When the user ’s current location approaches the registered location,
Alternatively, when leaving the registered place, the user is notified that there is an action to be taken at the place, and the like.

According to the invention described in Japanese Patent Application Laid-Open No. H11-15876, a history of processing performed when the user is in a place that can be represented by position information is stored, and a history matching the current position information is stored. To output the contents of the processing corresponding to the position information, or to select the processing performed in a place close to the current position information from the history and output the contents. I have.

[0010]

As for the information retrieval as described above, as an example, a management device that intensively holds information (location-related information) associated with a position, and receives (downloads) information from the management device ), The information retrieval system can be configured from the mobile terminal device that retains and uses the information for the search. In such an information retrieval system, information is effectively passed from the management device to the mobile terminal device ( (Download) technology is required.

[0011] As for the information registration as described above, for example, information associated with a position (position-related information)
An information registration system comprising a management device that centrally stores the information and a mobile terminal device that stores input information associated with the position and transmits (uploads) the information to the management device and registers the information. In such an information registration system, a technique for effectively transferring (uploading) information from the mobile terminal device to the management device is required.

The present invention has been made in view of such conventional circumstances. For example, a mobile terminal device receives information corresponding to a position of the mobile terminal device (the mobile terminal device) and a position near the mobile terminal device from a management device. To perform an information search system that can streamline the process of receiving (downloading) information from a management device by a mobile terminal device and temporarily storing the information when performing an information search based on the user's own location. And

According to the present invention, for example, when a mobile terminal device transmits registration information associated with location information to a management device and registers the registration information, the mobile terminal device temporarily stores and manages the registration information. An object of the present invention is to provide an information registration system or the like that can streamline processing of transmitting (uploading) to an apparatus. Another object of the present invention is to provide an information search device capable of presenting information suitable for the speed of an information search position when performing an information search based on an environment, for example.

[0014]

In order to achieve the above object, an information retrieval system according to the present invention has a mobile terminal device and a management device. Send (download) information to the device. The mobile terminal device is a mobile device.

That is, in the mobile terminal device, the information receiving means receives the information transmitted from the management device, the terminal-side information holding means holds the information received by the information receiving means,
The position information acquisition unit acquires position information (of the mobile terminal device), the information search unit searches information corresponding to the position information acquired by the position information acquisition unit from the terminal side information holding unit, and the information presentation unit The information retrieved by the information retrieval means is presented. Further, in the management device, the management-side information holding unit holds the position information and the information in association with each other, and the information transmission unit acquires information corresponding to a position near the mobile terminal device from the management-side information holding unit and performs the transfer. Transmit to the terminal device.

[0016] In the information retrieval system, the destination position estimating means estimates the position of the destination of the mobile terminal device, and the information transmission control means determines the information (or the information corresponding to the position estimated by the destination position estimating means). For example, the information corresponding to the estimated position and the position in the vicinity thereof is acquired from the management-side information holding unit by the information transmitting unit of the management device and transmitted (to the mobile terminal device).

Therefore, the position of the destination of the mobile terminal device is estimated, and information corresponding to the estimated position is transmitted from the management device to the mobile terminal device. The information presumed to be needed (at the next time) can be provided to the mobile terminal. Further, for example, if only the information corresponding to the estimated position of the destination of the mobile terminal device is transmitted from the management device to the mobile terminal device, information unnecessary for the mobile terminal device is transmitted from the management device. Thus, for example, the process of receiving (downloading) information from the management device by the mobile terminal device and temporarily storing the information in the terminal-side information holding unit (for example, a process such as a cache process) can be made more efficient. can do.

Here, as a preferred example, the position information acquisition means can be configured using a global positioning system (GPS), and as another example, a PHS (Personal
al Handy phone System) and the like, and may be configured to use a device that receives position information (for example, the base station device) wirelessly transmitted from a base station device and acquires the position information.

The information holding means (terminal-side information holding means and management-side information holding means) can be composed of, for example, a memory or database for storing information.
Various methods may be used for presenting information by the information presenting means. For example, a method of displaying and outputting information on a screen, a method of printing and outputting information by a printer, and a method of outputting information by a speaker from a speaker. The output method can be used.

Further, various information may be used as the information associated with the position information. Various modes may be used as a mode for associating the position information with the information. For example, a mode in which the position information is associated with the information on a one-to-one basis, or a mode in which a certain range of positions (that is, areas)
The information may be associated with the information, or the identification information (representative value) of the area may be associated with the information.

As information corresponding to a position near the mobile terminal device, for example, information associated with a position within a predetermined range (inside) around the position of the mobile terminal device may be used. For example, the predetermined range may be a symmetric range (for example, left-right symmetry, up-down symmetry, circular symmetry, or the like) about the position of the mobile terminal device, or may be an asymmetric (biased). Range) may be used. Further, the information corresponding to the position of the mobile terminal device may be transmitted from the management device to the mobile terminal device together with the information corresponding to the position near the mobile terminal device.

The information transmitted from the management device to the mobile terminal device includes, for example, information associated with the position information, and the position information, for example. That is,
In the mobile terminal device, by receiving a set of position information and information associated with each other from the management device, the information can be used for a position-based information search.

[0023] For example, when the mobile terminal device can grasp the position information associated with the information received from the management device based on the position of the mobile terminal device (the mobile terminal device), the mobile terminal device moves from the management device. It is also possible to omit the process of transmitting the position information to the terminal device. In the information communication between the mobile terminal device and the management device, for example, wireless communication may be used, or, for example, wired communication may be used.

The position of the destination of the mobile terminal device estimated by the destination position estimating means may be, for example, a single point, or may have a certain range (for example, an error range). It may be a position. Also, various methods may be used as a method of estimating the position of the destination of the mobile terminal device by the destination position estimating means.

More specifically, for example (as described later), the position of the destination of the mobile terminal device is estimated based on the speed and the moving direction of the mobile terminal device, or based on, for example, the time (advance of time). It is possible to estimate the position of the destination of the mobile terminal device, and, for example, when the travel route of the mobile terminal device (for example, a route that follows a plurality of sightseeing points) is determined in advance, the travel route , It is also possible to estimate the position of the destination of the mobile terminal device.

The function of the destination position estimating means and the function of the information transmission control means may be provided, for example, in any part of the information retrieval system, and specifically, for example, provided in the mobile terminal device. It may be provided in the management device, for example, or may be provided separately in both the mobile terminal device and the management device.

As an example, the destination position estimating means is provided in the mobile terminal device, and estimates the destination position of the mobile terminal device using the position information acquired by the position information acquiring means of the mobile terminal device. It is possible to Further, the mobile terminal device transmits information on the estimated position (destination of the mobile terminal device) to the management device. Then, as an example, the information transmission control unit is provided in the management device, and based on the information on the (estimated (moving destination of the mobile terminal device)) position received from the mobile terminal device, corresponds to the position. Information can be acquired from the management-side information holding means and transmitted by the information transmitting means.

The information retrieval system according to the present invention has a mobile terminal device and a management device, and transmits (downloads) information from the management device to the mobile terminal device with the following configuration. . Note that, similarly to the above, the mobile terminal device holds the position information acquisition unit that acquires the position information, the information reception unit that receives the information transmitted from the management device, and the information received by the information reception unit. A terminal-side information holding unit, an information search unit that searches the terminal-side information holding unit for information corresponding to the position information acquired by the position information acquisition unit, and an information presentation unit that presents the information searched by the information search unit. ing. In the same manner as described above, the management device obtains information corresponding to a position in the vicinity of the mobile terminal device from the management side information holding unit, and management information holding unit that associates and holds the position information and the information. There is provided information transmission means for transmitting to the mobile terminal device.

That is, in the information retrieval system, the speed detecting means detects the moving speed of the mobile terminal device, and the information transmission control means manages the information by the information transmitting means of the management device according to the moving speed detected by the speed detecting means. The position range of the information acquired from the side information holding unit and transmitted (the range of the position associated with the information) is controlled. In such a configuration, for example, the position of the destination of the mobile terminal device can be estimated based on the moving speed of the mobile terminal device, and the estimated position is usually the position of the mobile terminal device. It can be determined based on the moving speed.

Accordingly, the size of the position range of the information transmitted from the management device to the mobile terminal device is controlled according to the size of the moving speed of the mobile terminal device. It is possible to provide the mobile terminal device with information estimated to be required at the destination (at the next time). Further, for example, if only the information corresponding to the estimated position of the destination of the mobile terminal device is transmitted from the management device to the mobile terminal device, information unnecessary for the mobile terminal device is transmitted from the management device. Thus, for example, the process of receiving (downloading) information from the management device by the mobile terminal device and temporarily storing the information in the terminal-side information holding unit (for example, a process such as a cache process) can be made more efficient. can do.

Specifically, for example, when the moving speed of the mobile terminal device is large (fast) (for example, compared with a predetermined threshold value), information of a large position range (information of a wide range) is transmitted from the management device to the mobile terminal device. By transmitting the information to the terminal device, it is possible to provide the mobile terminal device with a wide range of information sufficient for movement at such a high speed (movement over a large distance). Also, for example, the moving speed of the mobile terminal device (for example, compared with a predetermined threshold)
When the distance is small (slow), information of a small position range (information of a narrow range) is transmitted from the management device to the mobile terminal device, so that movement at such a small speed (a small distance) is performed. ) Can be provided to the mobile terminal device.

Here, various methods may be used for detecting the moving speed of the mobile terminal device by the speed detecting means. For example, the moving speed may be obtained by the position information obtaining means of the mobile terminal device. The moving speed of the mobile terminal device can be detected based on the history of the position information (for example, the time and position information) of the mobile terminal device.

Further, the function of the speed detecting means and the function of the information transmission control means may be provided, for example, in any part of the information retrieval system, and specifically, for example, provided in the mobile terminal device. For example, it may be provided in the management device, for example, may be provided separately in both the mobile terminal device and the management device.

As an example, the speed detecting means is provided in the mobile terminal device, and is obtained by the position information obtaining means of the mobile terminal device as described above (of the mobile terminal device).
It is possible to detect the moving speed of the mobile terminal device based on the history of the position information (for example, time and position information). Further, the mobile terminal device transmits information on the detected moving speed (of the mobile terminal device) to the management device. As an example, the information transmission control means is provided in the management device, and is based on information received from the mobile terminal device (related to the detected moving speed of the mobile terminal device). It is possible to control the size and the like of the position range of the information acquired and transmitted from.

The information retrieval system according to the present invention has a mobile terminal device and a management device, and transmits (downloads) information from the management device to the mobile terminal device with the following configuration. . Note that, similarly to the above, the mobile terminal device holds the position information acquisition unit that acquires the position information, the information reception unit that receives the information transmitted from the management device, and the information received by the information reception unit. A terminal-side information holding unit, an information search unit that searches the terminal-side information holding unit for information corresponding to the position information acquired by the position information acquisition unit, and an information presentation unit that presents the information searched by the information search unit. ing. In the same manner as described above, the management device obtains information corresponding to a position in the vicinity of the mobile terminal device from the management side information holding unit, and management information holding unit that associates and holds the position information and the information. There is provided information transmission means for transmitting to the mobile terminal device.

That is, in the information retrieval system, the moving direction detecting means detects the moving direction of the mobile terminal device, and the information transmission control means gives priority to the information corresponding to the position in the moving direction detected by the moving direction detecting means. The information is transmitted from the management-side information holding unit by the information transmission unit of the management device.
In such a configuration, for example, it is possible to estimate the position of the destination of the mobile terminal device based on the moving direction of the mobile terminal device, and information corresponding to the estimated position is stored in the mobile terminal device. It is estimated that it will be needed at the next time (near future).

Therefore, the information corresponding to the position of the mobile terminal device in the moving direction is preferentially transmitted to the mobile terminal device, and is necessary for the mobile terminal device at the next destination (at the next time). The information estimated to be can be provided to the mobile terminal device with priority.

Specifically, as an example, when information (in a plurality of directions) around the mobile terminal device is transmitted from the management device to the mobile terminal device, the information corresponding to the position of the mobile terminal device in the moving direction is provided. If a configuration is adopted in which information is given priority and transmitted from the management device to the mobile terminal device, the information is required (estimated) for the mobile terminal device at its destination.
Information can be reliably provided to the mobile terminal device.

As another example, if only the information corresponding to the position in the moving direction of the mobile terminal device (estimated position of the destination) is transmitted from the management device to the mobile terminal device, It is possible to suppress transmission of information unnecessary for the device from the management device, whereby, for example, the mobile terminal device receives (downloads) information from the management device and temporarily stores the information in the terminal-side information storage unit. Processing (for example, processing such as cache processing) can be made more efficient.

Here, various methods may be used for detecting the moving direction of the mobile terminal device by the moving direction detecting means. For example, the moving direction is obtained by the position information obtaining means of the mobile terminal device ( The moving direction of the mobile terminal device can be detected based on the history (for example, time and position information) of the location information (of the mobile terminal device).

The function of the moving direction detecting means and the function of the information transmission control means may be provided in any part of the information retrieval system, for example.
For example, it may be provided in a mobile terminal device, for example, may be provided in a management device, and may be provided in a distributed manner, for example, in both a mobile terminal device and a management device.

As an example, the moving direction detecting means is provided in the mobile terminal device, and as described above, the history of the position information (of the mobile terminal device) obtained by the position information obtaining means of the mobile terminal device (for example, It is possible to detect the moving direction of the mobile terminal device based on (time and position information). Further, the mobile terminal device transmits information on the detected moving direction (of the mobile terminal device) to the management device. And, as an example, the information transmission control means,
Provided in the management device, based on information received from the mobile terminal device (related to the detected (moving terminal device) moving direction), giving priority to information corresponding to the position of the mobile terminal device in the moving direction, The information transmitting means can acquire and transmit the information from the management-side information holding means.

Further, in the information retrieval system according to the present invention, the information amount control means is controlled by the information transmission means of the management apparatus by the information transmission means of the management apparatus in accordance with the communication speed between the mobile terminal apparatus and the management apparatus. And the amount of information acquired and transmitted from the server is controlled. Therefore, the amount of information transmitted from the management device to the mobile terminal device is controlled in accordance with the communication speed between the mobile terminal device and the management device. It is possible to realize that (information) amount of communication is performed.

Specifically, for example, when the communication speed between the mobile terminal device and the management device is high (compared to a predetermined threshold value, for example), the information transmitted from the management device to the mobile terminal device is determined. On the other hand, if the communication speed between the mobile terminal device and the management device is small (for example, compared with a predetermined threshold value) while the amount is increased, the amount of information transmitted from the management device to the mobile terminal device is reduced. .

Here, as a method of controlling the amount of information transmitted from the management device to the mobile terminal device, for example,
A method of controlling the media of information transmitted from the management device to the mobile terminal device can also be used. As an example, since the amount of information of image information is generally larger than that of text information, if it is desired to reduce the amount of information transmitted from the management device to the mobile terminal device, only the text information is transmitted and the management device If it is desired to increase the amount of information to be transmitted to the mobile terminal device from, a control method of transmitting text information and image information can be used.

The function of the information amount control means may be provided, for example, in any part of the information retrieval system, and more specifically, may be provided in, for example, a mobile terminal device. May be provided separately, for example, in both the mobile terminal device and the management device. As an example, the information amount control means is provided in the management device, and controls the amount of information transmitted to the mobile terminal device according to the communication speed with the mobile terminal device.

Further, in the information retrieval system according to the present invention, when the moving speed of the mobile terminal device is high (for example, as compared with a predetermined threshold value), the transmission information control means relates to a position far from the position of the mobile terminal device. While the information is acquired from the management-side information holding unit by the information transmitting unit of the management device and transmitted, if the moving speed of the mobile terminal device is slow (for example, compared with a predetermined threshold), the information is close to the position of the mobile terminal device. Information on the position is acquired from the information storage means on the management side by the information transmission means of the management device and transmitted.

Therefore, the content (far and near) of the information transmitted from the management device to the mobile terminal device is controlled according to the speed of the mobile terminal device. It is possible to realize that (far and near) information is provided to the mobile terminal device. In other words, humans (users) usually tend to look far when their own moving speed is high, and look near when their own moving speed is low. In response to the change in the distance of the captured object, information of the content (perspective) suitable for the moving speed can be provided to (the user of) the mobile terminal device.

Here, various kinds of information may be used as the information on the position far from the position of the mobile terminal device and the information on the position near the position of the mobile terminal device. Specifically, for example, as information relating to a position far from the position of the mobile terminal device, information that appears far from the mobile terminal device (for example, information of a landscape at a distance of 1 km) can be used. As the information on the near position, information that is seen from the mobile terminal device near (for example, information on a landscape within 100 m or a plant on the ground) can be used.

As described above, when the content (far and near) of the information provided to the mobile terminal device is controlled in accordance with the moving speed, for example, for a user walking with the mobile terminal device, a nearby flower is provided. Information can be provided,
For example, a user carrying a mobile terminal device and riding on a bus can be provided with information on a relatively distant landscape seen from the bus, for example, carrying a mobile terminal device and riding on a bullet train. The user can be provided with information on the city that will pass next, and for example, the user who is carrying the mobile terminal device and is on an airplane can be provided with information on the country that will pass over the sky, etc. can do.

The functions of the transmission information control means include:
For example, it may be provided in any part of the information retrieval system, specifically, for example, it may be provided in a mobile terminal device, for example, it may be provided in a management device. It may be provided separately in both the device and the device. As an example, the transmission information control means is provided in the management device, and controls the content (far and near) of information transmitted to the mobile terminal device based on the moving speed of the mobile terminal device notified from the mobile terminal device. I do.

The information registration system according to the present invention has a mobile terminal device and a management device, and transmits (uploads) information from the mobile terminal device to the management device with the following configuration. . The mobile terminal device is a mobile device.

That is, in the mobile terminal device, the information input means inputs the registration information, the position information obtaining means obtains the position information (of the mobile terminal apparatus), and the information holding means is input by the information input means. The registration information and the position information acquired by the position information acquisition unit when the registration information is input are held in association with each other, and the information transmission unit is registered with the registration information (for example, the registration information registered in the management device). Is obtained and transmitted to the management device.
In the management device, the information receiving means receives the information transmitted from the mobile terminal device, and the information registration holding means registers and holds the information received by the information receiving means.

In the information registration system, when the position of the position information associated with the registration information held in the information holding means of the mobile terminal device is out of a predetermined range near the position of the mobile terminal device, The information transmission control means acquires the registration information from the information holding means by the information transmission means and transmits the registration information to the management device.

Therefore, when the position of the position information associated with the registration information held by the mobile terminal device falls outside a predetermined range near the position of the mobile terminal device, the registration information is transmitted from the mobile terminal device. Since the registration information is transmitted to the management apparatus, the registration information (for example, a plurality of pieces of registration information) can be collectively transmitted from the mobile terminal apparatus to the management apparatus and registered. It is possible to increase the efficiency of processing (for example, processing such as cache processing) of temporarily storing data in the storage unit and transmitting (uploading) to the management apparatus.

As a preferred mode, for example, as the predetermined range (near the position of the mobile terminal device), a range in which the registration information held by the mobile terminal device is used for information search or the like (or, When the registration information is necessary for the mobile terminal device, the registration information is held by the mobile terminal device, and when the registration information held by the mobile terminal device becomes unnecessary, The registration information can be transmitted to the management device and registered.

Here, various information may be used as the registration information input by the information input means. Also,
As a method of inputting registration information by the information input means,
Various methods may be used. For example, a method of inputting information received from a user, a method of inputting information stored on a (external) recording medium, or the like may be used.

The registration information transmitted from the mobile terminal device to the management device is transmitted, for example, with location information associated with the registration information. In other words, the management apparatus can receive the pair of the positional information and the registration information associated with each other from the mobile terminal device, and register the information in association with each other. For example, in a case where the management device can grasp the position information associated with the registration information received from the mobile terminal device based on the position of the mobile terminal device, etc., the position information from the mobile terminal device to the management device can be obtained. May be omitted.

The functions of the information transmission control means include:
For example, it may be provided anywhere in the information registration system, specifically, for example, it may be provided in a mobile terminal device, for example, it may be provided in a management device, and for example, It may be provided separately in both the device and the device. As an example, the information transmission control means is provided in the mobile terminal device, based on the position information acquired by the position information acquisition means of the mobile terminal device,
The registration information out of a predetermined range from the position of the self (the mobile terminal device) is acquired from the information holding unit by the information transmission unit and transmitted to the management device.

Further, in the information registration system according to the present invention, when the registration information held in the information holding means of the mobile terminal device is acquired from the information holding means by the information transmitting means and transmitted, the information deleting means is provided. The registration information is deleted from the information holding unit. Therefore, for example, when the registration information held by the mobile terminal device becomes unnecessary, the registration information can be deleted (erased) from the information holding device, whereby, for example, the registration information can be transferred to the information holding device by the mobile terminal device. The process of temporarily storing and transmitting (uploading) to the management device (for example, a process such as a cache process) can be made more efficient.

Here, the function of the information deleting means may be provided, for example, in any part of the information registration system, and more specifically, may be provided in, for example, a mobile terminal device. May be provided separately, for example, in both the mobile terminal device and the management device. As an example, the information deletion unit is provided in the mobile terminal device, and acquires registration information from the information holding unit based on the position information obtained by the position information obtaining unit of the mobile terminal device or by the mobile terminal device. It is possible to delete the registration information from the information holding means based on the situation of sending (reading) the information.

The information retrieval apparatus according to the present invention retrieves and presents registration information corresponding to environment information with the following configuration. That is, the information holding unit holds the registration information and the environment information in association with each other, and the environment information obtaining unit obtains environment information including the moving speed of the information search position at the time of information search (for example, the (moving) speed of the user). The information searching means searches the information holding means for registration information corresponding to the environment information obtained by the environment information obtaining means, and the information presenting means searches the registration information searched by the information searching means at the information search position (for example, Present).

At this time, in the information search apparatus, the presentation information control means determines that the moving speed of the information search position acquired by the environment information acquisition means is high (for example, as compared with a predetermined threshold value). While information about a distant position is presented by the information presenting means, if the moving speed of the information retrieval position acquired by the environment information acquiring means is slow (for example, compared with a predetermined threshold), information about a position close to the information retrieval position is obtained. Is presented by the information presenting means.

Therefore, the content (perspective) of the information presented at the information search position is controlled according to the magnitude of the speed of the information search position. Is provided at the information search position. The information search position is a position where information is searched, for example, a position where a user searching for information exists.

Here, the environment information may be, for example, only information on the moving speed of the information search position, or
For example, other information (for example, information on the position of the information search position) may be included together with the information on the moving speed of the information search position. Various methods may be used to control the content (perspective) of the information presented by the information presenting means.

Next, as an example of a preferable apparatus (system) to which the present invention can be applied, an example of an information registration apparatus (information registration system) or an information search apparatus (information search system) will be described. In the information registration apparatus, for example, registration information input by a user and information of one or more environments at the time of the input are registered in association with each other and stored by a storage unit (information storage unit). Specifically, in the information registration device, an input pad, a camera, and the like for a user to input fragmentary registration information such as a memo, a photo, and a voice comment.
A GPS, an altimeter, a speedometer, a thermometer, a hygrometer, a clock, etc., which include input means such as a microphone and acquire information on the environment outside the device such as a position, altitude, speed, temperature, humidity, and time at the time of registration. Environmental information acquisition means.

As an example, the longitude, latitude, altitude, speed, date provided by a clock, temperature provided by a thermometer, humidity provided by a hygrometer, humidity provided by a hygrometer, and the like provided by the GPS are used as environmental conditions. It can be used as information, and is not limited to these, and is obtained by, for example, atmospheric pressure, air volume / wind direction, sound intensity / frequency, light amount / ultraviolet light amount / infrared light amount, radiation dose, or other chemical analysis methods Numerical values and the like can be used as environmental information.

Here, as a method of associating the registration information with the environment information, for example, a method of associating one-to-one or a method (environment attribute) in which the information of the environment (part or all) has a certain width (environment attribute) is used. A method of associating with the registration information, for example, identification information (representative value) of such an environmental attribute (environmental range)
A method of associating the registration information with the registration information can be used. In addition, the information registration apparatus can register not only a configuration that allows registration only when the user is in the environment, but also associates the registration information with the environment information anytime and anywhere (at any time or at any place). It can also be configured.

If the environment range at the time of registration is set smaller than the environment range required at the time of search (search environment range), for example, a slight error may occur in the value of environment information. In this case, it is possible to realize a search for registered information that matches the actual environment. Even if the user environment (the environment at the time of the search) changes, for example, According to this, it is possible to realize that the corresponding information search is performed smoothly, and it is also possible to realize, for example, that the search processing of the registered information is performed easily and at high speed.

As an example, it is preferable that the size of the minimum environment range (at the time of registration) is set to the degree of accuracy of the value of the environment information obtained by the environment information obtaining means. The accuracy of the GPS that is not performed is 10 m (about latitude and longitude around Japan).
(3 seconds to 0.4 seconds), so when this system is used, (about latitude and longitude around Japan) 3
It is preferable to use a position range having a size of about m (0.1 seconds) as the minimum position range. Here, “second” is “xx
× degrees △△ minutes XX. Seconds ”.

In the information search device, for example, when a search instruction input (for example, input of a search start command, input of a search key (keyword), input of a search range, power-on, etc.) is performed, And searching for the registration information corresponding to the environment information based on the environment information in. And presenting the search result. Here, as a method of presentation, for example, a method of displaying and outputting information on a screen, a method of printing and outputting information by a printer, a method of outputting information by voice from a speaker, and the like can be used.

Further, as environment information for retrieval, for example, information (environmental conditions) obtained by giving a range to (part or all) environment information may be used. In this case, the size of the search environment range can be specified by, for example, a user, or can be set in advance, for example. In this case, information searched for each environment range included in the search environment range can be presented.

As described above, in the information registration apparatus and the information retrieval apparatus, for example, the environment information and the registration information are associated one-to-one and the registration information is searched using the environment information as a key. And registering information and searching for registration information using environment information as a key, for example, associating environment information with registration information and searching for registration information using environmental conditions as a key, The environment information and the registration information can be associated with each other, and the registration information can be searched using the environment condition as a key. Further, for example, the information registration device and the information search device can be integrated to constitute an information registration and search device.

Further, for example, an information registration device and an information search device are configured by separately providing a (mobile) terminal device that can be carried and carried by a user and a management device that manages registration information. It is also possible. In such a configuration, the terminal device acquires the information on the environment, associates the acquired environment information with the registration information, and transmits and registers the acquired environment information to the management device, or transmits the acquired environment information to the management device. For example, receiving and presenting registration information corresponding to the environment information returned from the management device is performed. In addition, the terminal device and the management device are wirelessly connected (for example,
(May be wired).

Further, for example, one management device can collectively manage registration information corresponding to various environments, or, for example, for each position, a (different) management device that stores registration information corresponding to the position. Can also be installed.

As a method of retrieving information, for example, it is possible to adopt a configuration in which information is retrieved (selected) on the management device side, and it is also possible to adopt a configuration in which information is retrieved on the terminal device side, for example. In addition, for example, it is also possible to adopt a configuration in which information is searched in a certain range on the management device side, and more detailed information is searched from the information in the certain range on the terminal device side.

Further, for example, the management device can be composed of a management unit for managing registration information and one or a plurality of wireless communication units (for example, such as a wireless base station device) for performing wireless communication. In a simple configuration, as an example, the management unit and the wireless communication unit are installed separately from each other, the wireless communication unit wirelessly communicates information with the terminal device, and the management unit communicates the information with the wireless communication unit. It communicates by wire or wirelessly.

Further, in the terminal device, for example, the main body and the position information obtaining means (for example, GPS) part can be configured as a detachable separate body, or the position information obtaining means part can be attached to the main body (the terminal device). A built-in configuration can also be used. When GPS is used, it is preferable to dispose a GPS receiver above the head and shoulders of the user because GPS radio waves from satellites can be easily received by the GPS receiver.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment according to the present invention will be described with reference to the drawings. In this example, an information sharing system to which the present invention is applied will be described as an example. The information sharing system of the present example includes, for example, a mobile terminal device (for example, a plurality of mobile terminals) that can be carried by a user and move, and a server device (management device) that manages information and wirelessly communicates with the mobile terminal device. Is provided. The server device is installed (for example, fixedly) by an administrator, for example.

First, a configuration example of a mobile terminal device and a server device provided in the information sharing system of the present example will be described. FIG.
FIG. 2 is a block diagram illustrating a configuration example of a mobile terminal device provided in the information sharing system of the present example. As shown in the figure,
The mobile terminal device according to the present embodiment includes an information presenting unit 1 for presenting information such as registration information, an information input unit 2 for inputting information, and a position information acquiring unit for acquiring information on a position of the mobile terminal device (the mobile terminal device). 3, information (unit) holding means 4 for temporarily holding information transmitted from the server device and registered information (on the mobile terminal side), and information (user information) on the user's interest (of the mobile terminal device) ), A movement history holding means 6 for holding information on the movement history of the mobile terminal device itself, an acquisition information determination means 7 for determining information to be acquired from the server device, and a server. Transmission information determining means 8 for determining information to be transmitted to the device, communication means 9 for performing (wireless) communication with the server device (on the mobile terminal side), and various processes (for example, information search) in itself (the mobile terminal device) place Performs control such) (and a mobile terminal side) control section 10.

FIG. 2 is a block diagram showing a configuration example of a server device provided in the information sharing system of this embodiment. As shown in the figure, the server device of the present example holds (server side) information (unit) holding means 11 for holding shared information (shared information) (for users of a plurality of mobile terminal devices, for example).
Information unit transmitting means 12 for transmitting information necessary for the mobile terminal device to the mobile terminal device (server side), and information unit registering means 13 for registering information received from the mobile terminal device as shared information (server side). And (communication means) 14 (server side) for performing (wireless) communication with the mobile terminal device.

In this example, as described above, the user information holding means 5, the movement history holding means 6, the acquisition information determination means 7, and the transmission information determination means 8 are provided on the mobile terminal device side. However, for example, some or all of these means may be provided on the server device side. In this case, the server device uses, as an example, an identifier that uniquely identifies the mobile terminal device or the user. Then, information about each mobile terminal device is held and distribution information is determined.

Next, a process for transmitting information from the server device to the mobile terminal device will be described. FIG. 3 shows an example of a procedure of a process in which a mobile terminal device used by a user receives information from a server device, and searches for and presents the received information.

In this example, it is assumed that shared information is held in the server-side information unit holding means 11 in the form shown in FIG. In this example, a plurality of pieces of information related to a specific location are stored in a file having a name based on the location information. Then, the file exists for each district (a position (area) having a certain range), and "public information"
Classification by genre such as "history information", "biological information", "memo information", "moving at high speed", "moving at low speed"
Classification by moving speed, such as "multimedia"
It is divided and stored in a plurality of directories based on various classifications such as classification by media (file size) such as “text”.

In each file, fragmentary information (position-related information) is stored together with the relevant position of the information in a form as shown in FIG. 5, for example. In the embodiment shown in the figure, an ID section 21 for storing an identification number (ID) of information and a name section 2 for storing a name of information are provided.
2, a content section 23 for storing information content, and a keyword section 24 for storing information keywords.
Also, in this example, the files are subdivided,
For example, it is also possible to use a configuration in which a database file is created by integrating all or a part of the data, and a file is dynamically created by combining necessary information according to a request.

In the procedure of the process shown in FIG. 3, first,
The position information acquisition means 3 of the mobile terminal device calculates the position where the mobile terminal device is currently located (step S1). Here, a position acquisition system using a satellite called GPS is most often used as the position information acquisition means 3. The calculated position information is stored in the movement history holding unit 6 as a movement history.

Next, the mobile terminal device determines (checks) whether or not information relating to the current position (of the mobile terminal device) is stored in the information unit holding means 4 of the mobile terminal device ( Step S2). Here, the details of this processing are shown in the flowchart of FIG. In this example, the mobile terminal device is "35 degrees 42 minutes 56 seconds north latitude
9, east longitude 139 degrees 44 minutes 03 seconds 0 ".

That is, first, the mobile terminal device obtains a movement history from the movement history holding means 6 (step S2).
1) Calculate the average speed (average speed) of the mobile terminal device based on the acquired movement history (step S2)
2). For example, if the average speed of the mobile terminal device is calculated to be 4.2 km / hour, in this case, the moving speed of the mobile terminal device is regarded as “slow”.

Next, in the mobile terminal device, a communication speed (communication speed of a communication line) that can be established at present is acquired by the communication means 9 (step S23). For example, if a communication speed of 64 kbps is obtained, in this case, it is regarded as “low-speed communication” and “text” information is obtained from the server device.

Next, the mobile terminal device presents the user with an interest designation dialogue 31 on a screen as shown in FIG. 7, for example, and acquires a genre of interest to the user based on the input from the user ( Step S2
4). In this example, “history” and “creature” are selected, and in this example, “memo” is also acquired by default in this example. In addition, it is also possible to adopt a configuration in which the user information such as the genre is acquired from the user information holding means 5, for example.

Through the above processing, the acquisition information determination means 7 of the mobile terminal device determines a file (a file related to the current position) to be acquired from the server device (step S25). In this example, the files to be acquired are "N.35.42.50-E.139.44.00-history-low-speed-text""N.35.42.50-E.139.44.00-biology-low-speed-text""N .35.42.50-E.139.44.00-memo-low-speed-text ".

Information is stored in the information unit holding means 4 of the mobile terminal device, for example, as shown in FIG.
The ATE directory stores memo information, and the PUBLI
The "C" directory stores other information (other than notes). Then, in the procedure of the processing shown in FIG. 3, the mobile terminal device then “N.35.42.50-E.139.44.00-history-low-speed-text” file and “N.35.42.50-E .139.4
For 4.00-biology-slow-text files, see PUBLI
C ”directory and search for“ N.35.42.50-
The E.139.44.00-memo-low-speed-text file is searched in the "PRIVATE" directory, and it is checked whether a file with the same name exists in these directories (step S3).

Here, if there are any missing files (not present in the directory in the information unit holding means 4 on the mobile terminal side), these files are respectively stored in the information unit holding means 11 of the server device. Since it is known that they exist in the "history / slow / text", "creature / slow / text", and "memo / slow / text" directories, the server device, for example, based on a request from a mobile terminal device, The information unit transmitting unit 12 transmits and copies (saves) these files to the corresponding directory in the information unit holding unit 4 on the mobile terminal side through the communication unit 14 on the server side and the communication unit 9 on the mobile terminal side. (Step S11). At this point, the mobile terminal device stores information related to the current position of the mobile terminal device (and information related to a position around the current position, for example, when held in the information unit holding unit 4). You are ready to search.

Therefore, the mobile terminal device searches for relevant information of the current position of the mobile terminal device (or related information around the current position) (step S4), and stores the search result in a form as shown in FIG. The information is presented to the user by the information presenting means 1 (step S5). When the user wants to know more detailed information, the user selects an arbitrary information title from a list of search results as shown in FIG. Is presented (step S
5).

Here, if there is another user event process that should be processed immediately by the system (step S6), the user event process is performed (step S6).
12) The download process (of information from the server device to the mobile terminal device) is temporarily terminated. On the other hand, if there is no other execution routine of the process to be processed immediately by the system and the system is in the idling state (step S6), the mobile terminal device acquires the position-related information around the position of the mobile terminal device. Is started (step S7).

The details of this process are shown in the flowchart of FIG. In this example, three 3 × 3 areas (areas in which nine rectangles are divided with the current position as the center) are defined for rectangles whose latitude and longitude are divided every 10 seconds (about 300 m). Defined as "around". Currently, the mobile terminal is "35 degrees 42 minutes 56 seconds north latitude
9, It is assumed that it is located at 139 degrees 44 minutes 03 seconds 0 east longitude.

That is, first, the mobile terminal device obtains a movement history from the movement history holding means 6 (step S3).
1) Calculate the average speed (average speed) of the mobile terminal device based on the acquired movement history (step S3).
2). For example, if the average speed of the mobile terminal device is calculated to be 4.2 km / hour, in this case, the moving speed of the mobile terminal device is regarded as “slow”.

Next, in the mobile terminal device, a communication speed (communication speed of a communication line) which can be established at present is acquired by the communication means 9 (step S33). For example, if a communication speed of 64 kbps is obtained, in this case, it is regarded as “low-speed communication” and “text” information is obtained from the server device.

In this example, the genre of interest to the user has already been obtained from the user (in the process of step S24 shown in FIG. 6), and “history”, “creature”, and “memo” have been obtained. Target (Step S3
4).

With the above processing, the acquisition information determination means 7 of the mobile terminal device determines a file to be obtained from the server device (step S35). In this example, the file to be acquired from the server device is, for example, a file corresponding to the latitude and longitude within ± 10 seconds as shown in FIG.
Genre, the moving speed is "low speed", and the content is a file based on "text".

In the figure, among the files to be acquired from the server device, those actually stored in the information unit holding means 4 of the mobile terminal device are marked with a circle, while
Those that are not actually held in the information unit holding means 4 of the mobile terminal device are marked with an x, and the files with the x mark are to be downloaded (from the server device to the mobile terminal device). Is detected as a missing file by the mobile terminal device (step S36).

Next, in the processing procedure shown in FIG.
In the mobile terminal device, for example, if there is no file to be obtained from the server device (step S8), the process is terminated, while if there is a file to be obtained from the server device (insufficient file) (step S8). S
8) It is determined in what order such missing files are downloaded through the network (step S9).

FIG. 13 is a flowchart showing this processing. That is, first, the mobile terminal device obtains a movement history from the movement history holding means 6 (step S41). Here, the acquired movement history is, for example, FIG.
4, it is assumed that the movement history 41 is as indicated by the solid line arrow.
An average speed vector 42 as indicated by a double-lined arrow in the figure is calculated (step S42). Then, the mobile terminal device determines a file acquisition order based on the calculated speed vector (step S43).

Specifically, FIG. 15A shows an example in which the speed vector 42 is displayed on the azimuth used to determine the download order of the acquired files.
In the algorithm in FIG.
The priority order is determined preferentially from those close to the angle Θ of 2 (in FIG. 7A, the angle based on the direction of “east”). In the example of FIG. 6A, the direction closest to the velocity vector 42 is “northeast”, the next is “north”,..., The next (the farthest direction) is “southwest”. In FIG. 15 (b), the current position of the mobile terminal device is indicated by an asterisk, and the order determined in this way is indicated using numerical values of “〜”. As described above, “Northeast”, “ North ”, etc., and the last is“ Southwest ”. In this way,
The file download (transfer) order is determined based on the direction.

On the basis of the order determined as described above, the information unit transmitting means 12 of the server device transmits the file stored in the information unit holding means 11 on the server side in response to a request from the mobile terminal device, for example. Then, it is transmitted to the information unit holding means 4 of the mobile terminal device via the communication means 14 on the server side and the communication means 9 on the mobile terminal side and stored (step S10).

Here, FIGS. 16 (a) to 16 (j) show an example of a state in which files are downloaded in the order determined as described above. The position related to the file held by the means 4 is sequentially enlarged like a gray part around the current position of the mobile terminal device indicated by an asterisk.

When the obtained files are downloaded from the server device to the mobile terminal device in the order as shown in this example, the information group related to the rectangle located in the (progressing) direction of the speed vector of the mobile terminal device is downloaded preferentially. Therefore, for example, even if the mobile terminal device enters another rectangular area while moving, there is a high possibility that the download of the information related to the rectangular area has already been completed. In this example, 3 × 3
The processing is performed with the nine areas as "peripheries". Considering actual movement, for example, as shown in FIG. 17, an area as close to a circle as possible with the current position of the mobile terminal device indicated by an asterisk (gray) It is also preferable that the file is downloaded while setting the priority order.

Next, the process of transmitting information from the mobile terminal device to the server device and registering the information will be described. In the information sharing system of this example, it is possible to transmit and register information related to the position from the mobile terminal device to the server device.

FIG. 18 is a flowchart showing this process. That is, first, in the mobile terminal device, the user uses the screen as shown in FIG.
Is input (step S51). Here, in the example of the screen shown in the figure, the information unit registration button 51 pressed when registering information (unit), the information (unit)
Information unit search button 52 pressed when searching for
And a search result display area 53 for displaying information search results
And a name area 54 for inputting and displaying information names, and a content area 55 for inputting and displaying text information contents.
And an image area 56 for inputting and displaying image information, and a keyword area 57 for inputting and displaying information keywords.
Is provided.

The information input by the user is associated with, for example, the position information obtained by the position information obtaining means 3 of the mobile terminal device at the time of the input, and the “PRIVATE” in the information unit holding means 4 on the mobile terminal side is stored. Is stored as memo information in a directory (step S52).

When such a storage process is performed, the mobile terminal device registers the file existing in the “PUBLIC” directory in the information unit holding means 4 of the mobile terminal device with the “PRIVLIC” directory.
By searching all the files existing in the “ATE” directory, information downloaded and saved from the server device and information registered (saved) by itself can be searched and presented to the user. At this point, the information (registration information) registered in the information unit holding means 4 on the mobile terminal side is not reflected on the server side.

Next, a description will be given of a process of deleting unnecessary information by the mobile terminal device and a process of transmitting (uploading) information registered by the mobile terminal device as described above to the server device. In FIG. 20, when the position related to the information registered as described above is out of the peripheral range of the position of the mobile terminal device, the registration information is uploaded from the mobile terminal device to the server device. An example of a procedure such as processing is shown.

That is, first, the transmission information determining means 8 of the mobile terminal device calculates the range of the peripheral information of the mobile terminal device based on the position of the mobile terminal device obtained by the position information obtaining means 3. Here, in this example, a 3 × 3 rectangular area centered on the current position of the mobile terminal device is set as the peripheral information effective range. Then, the transmission information determining means 8 of the mobile terminal device determines whether or not the information file associated with the position other than the peripheral information effective range is stored in the information unit holding means 4 on the mobile terminal side (check). ) (Step S61).

Here, if the information is associated with a position other than the peripheral information effective range and is not information registered by itself (mobile terminal device) (in this example, “PUBLI
If the “information in the“ C ”folder) exists (step S62), the mobile terminal device deletes the file of the information from the information unit holding unit 4 (step S63).

Next, in the mobile terminal device, information registered by itself (the mobile terminal device) (in this example, “PRI
VATE ”folder (memo file), and determines (checks) whether there is registration information associated with a position other than the peripheral information effective range (step S64).
When such registration information exists, the transmission information determination means 8 of the mobile terminal device transmits the registration information to the server device via the communication means 9 on the mobile terminal side and the communication means 14 on the server side ( Upload). Then
In the server device, the information unit registration unit 13 registers the registration information received from the mobile terminal device in the memo file in the information unit holding unit 11 on the server side (Step S).
65). Then, in the mobile terminal device, the registration information registered by the server device is stored in the information unit holding means 4 on the mobile terminal side.
(Step S66).

FIG. 21 specifically shows an example of a situation in which the mobile terminal device moves after registering information in the information unit holding means 4 of the mobile terminal. In the example of the figure, the position of the mobile terminal device is indicated by using an asterisk, and after the mobile terminal device newly registers information (registration data 61) at the position of the lower left asterisk in the figure, it moves to the upper right. Moving toward the direction of.

FIGS. 22 (a) to 22 (c) show that:
In the case where the mobile terminal device registers information and moves as shown in FIG. 21, the position of the mobile terminal device is indicated using an asterisk, and the position of the mobile terminal device is used for information search by the mobile terminal device. The range of positions related to information that needs to be held in the information unit holding unit 4 is shown in gray, and the range of positions related to information that is unnecessary for information search by the mobile terminal device is indicated by x. This is indicated using a mark.

First, in the initial state (the state where the mobile terminal device is located at the position of the star at the lower left in FIG. 21), FIG.
(A) The file associated with the position shown in gray in FIG. 3 is held (cached) in the information unit holding means 4 on the mobile terminal side. Entered information (registration data 6
