However, some of the functional modules may be hardware such as other processors, digital circuits, or analog circuits. Each functional module can be rephrased as a part, a functional part, or a means.

The switching unit 100b is a part that switches between the operation of the input unit 100c and the operation of the output unit 100d, and operates according to the operation of the terminal device 10 by the user who may be a pedestrian, for example, switching input from the monitor 14. For example, the switching unit 100b switches between the operation screen of the input unit 100c shown in FIG. 3, that is, the input screen, and the operation screen of the output unit 100d, that is, the output screen shown in FIG.

The input unit 100c includes an input acquisition unit 100e and a transmission unit 100f. The input unit 100c functions, for example, to input information (input information) to be provided to other pedestrians or the like who may possess other terminal devices 10, which are other users. This input information is transmitted to and provided to the server device 20 .

The input acquisition unit 100 e acquires input from the input screen shown in FIG. 3 and/or voice input from the microphone 18 . An input from the microphone 18 is converted into text by a voice-to-character converter (not shown) and acquired as character information. Audio information itself may also be obtained. The input acquisition unit 100e also associates the acquired information, that is, the input information, with predetermined position information. The predetermined location information is, in principle, location information acquired from the location information receiving unit 12 , but may be location information of a location specified on the monitor 14 by an operator such as a user of the terminal device 10 . For example, the predetermined location information is information including latitude and longitude.

The transmission unit 100f transmits the information acquired by the input acquisition unit 100e to the server device 20 in a state of being associated with predetermined position information. The transmission unit 100f may store this information in the storage unit 102 for a certain period of time or as long as there is no deletion request. Note that the storage unit 102 stores registration information RI for identifying users for use of the system S. FIG. When transmitting the information to the server apparatus 20, the transmission unit 100f preferably transmits identification information in the registration information RI, such as ID information such as a terminal ID or a user ID, attached to the information. In this case, when storing the information in the information database DB1, the server device 20 preferably stores the information so that the information can be retrieved by the user ID as well.

The information acquired by the input unit 100c and transmitted to the server device 20 can be various types of information. including. The assistance information may particularly include danger information, ie, hazard information, which is information that informs pedestrians of danger. Attributes are used to determine the types of such input information. The "attribute" includes the attribute in this support information, and may be, for example, "hazard" in hazard information, "entertainment" in entertainment information, etc., and may be acquired by the input acquisition unit 100e and associated with the input information.

The output unit 100d includes an information extraction unit 100g, an attribute determination unit 100h, a display output unit 100i, and an audio output unit 100j. The output unit 100d functions to output information provided to the server device 20 by, for example, other pedestrians who may possess other terminal devices 10, which are other users, that is, input information. The output unit 100d can also output input information from the terminal device 10 itself of the output unit 100d.

The information extraction unit 100g extracts input information of predetermined positional information with which the positional information of the terminal device 10 acquired from the positional information receiving unit 12 has a predetermined relationship. Specifically, when the terminal device 10 reaches within a predetermined distance of the position of the predetermined position information of the input information such as the support information that is transmitted to the server device 20 and stored here, the information extraction unit 100g , extracting that information. In particular, here, since part or all of the information database DB1 provided from the server device 20, for example, periodically or irregularly, is stored in the storage unit 102 of the terminal device 10, it is stored in the storage unit 102. The information extracting unit 100g searches the information database DB1 stored therein to extract such information. It should be noted that the information extraction unit 100g of the terminal device 10 is stored in the storage unit 202 of the server device 20, for example, by directly accessing the server device 20 or a device related thereto (another information processing device) in real time. Such information may be extracted. The predetermined distance may be 0 m or a distance of 5 m or more and 10 m or less, but here it is a distance according to the map displayed on the monitor 14 of the terminal device 10 as shown in FIG. However, the predetermined distance is not limited to this, and may be set arbitrarily.

When the information extracted by the information extraction unit 100g, that is, the input information has an attribute, the attribute determination unit 100h determines whether or not the attribute is the desired attribute of the user who owns the terminal device 10. FIG. Also, the attribute may be identification information specified by the side that provided the information. In this case, the information extracted by the information extraction unit 100g specifies the side to which the information is provided, and ID information such as a terminal ID is attached as an attribute. The attribute determination unit 100h can determine whether or not the ID information of the terminal device 10 matches.

The display output unit 100i outputs, to the monitor 14, the information extracted by the information extraction unit 100g that the attribute determination unit 100h has determined to match the attribute or no attribute.

The audio output unit 100j outputs, from the speaker 16, the information extracted by the information extraction unit 100g that the attribute determination unit 100h has determined to match the attribute or no attribute. Here, audio output by the audio output unit 100j is performed only when audio output is desired, but audio output may be performed in all cases. It should be noted that when outputting audio, it is preferable that the text information is converted into audio information by the audio-to-text conversion unit. If the audio information itself is stored, it may be output as it is.

The information storage unit 100k acquires part or all of the information database DB1 provided from the server device 20 described later, stores it in the storage unit 102, and updates the information database DB1 in the storage unit 102, for example.

The server device 20 is an information processing device, includes a so-called computer, and can function as part of the system S. The server device 20 has a control unit 200, a storage unit 202, and a communication unit 204, similarly to the terminal device 10, and is connected to each of the plurality of terminal devices 10 via the network N. The server device 20 further includes a monitor 22 and an input section 24 . Note that the monitor 22 is an example of a display device, and the monitor 22 is also a so-called touch panel, and is an output device as well as an input device. The input unit 24 is, for example, a keyboard and a mouse.

The control unit 200 of the server device 20 is a computer that controls the server device 20 based on information obtained via the network N or information obtained via the monitor 22 and/or the input unit 24 . The control unit 200 is an example of control means for controlling the operation of the server device 20 and the like.

The control unit 200 has a CPU and a main storage unit, and executes information processing by a program. CPU is also called a processor. However, the CPU is not limited to a single processor, and may have a multiprocessor configuration. Also, a single CPU connected with a single socket may have a multi-core configuration. At least part of the processing of each unit described above may be performed by a processor other than the CPU, such as a dedicated processor such as a Digital Signal Processor (DSP) or Graphics Processing Unit (GPU). Also, at least part of the processing of each unit described above may be performed by an integrated circuit (IC) or other digital circuits. Also, at least part of the above units may include an analog circuit. The main storage unit of the control unit 200 is an example of a main storage device. The CPU in the control unit 200 executes a computer program developed in the main storage unit and provides various functions. The main storage unit in the control unit 200 stores computer programs and/or data executed by the CPU. A main storage unit in the control unit 200 is a dynamic random access memory (DRAM), a static random access memory (SRAM), a read only memory (ROM), or the like.

Control unit 200 is connected to storage unit 202 . The storage unit 202 is a so-called external storage unit, is used as a storage area that assists the main storage unit of the control unit 200, and stores computer programs executed by the CPU of the control unit 200 and/or data. The storage unit 202 is a hard disk drive, Solid State drive (SSD), or the like.

The control unit 200 includes, as functional modules, an information acquisition unit 200a, an attribute determination unit 200b, a storage execution unit 200c, and an information provision unit 200d. Each functional module is realized by, for example, executing a program stored in the main storage unit and/or the storage unit 202 by the control unit 200, that is, the CPU thereof. However, some of the functional modules may be hardware such as other processors, digital circuits, or analog circuits. Each functional module can be rephrased as a part, a functional part, or a means.

The information acquisition unit 200 a acquires information transmitted and provided from the terminal device 10 . The information acquisition unit 200a then sends the information to the attribute determination unit 200b. Note that this information is input information such as the support information described above, and is associated with predetermined position information such as position information of the terminal device 10 or the like, that is, is linked.

The attribute determination unit 200b determines attributes of information sent from the information acquisition unit 200a. In this determination, the data of the attribute database DB2 stored in the storage unit 202 is used, for example, it is determined whether or not it belongs to the attribute such as "hazard", and one or more suitable attributes are selected, further associated with that information. The attribute may be added to the input information on the terminal device 10 side. In this case, it is not necessarily required that the attribute determination section 200b further determines the attribute.

The storage execution unit 200c stores the information acquired by the information acquisition unit 200a and the attributes (which may include identification information) determined by the attribute determination unit 200b in the information database DB1 of the storage unit 202. This storage is performed to store the input information in a retrievable manner with associated predetermined location information. Further, this storage is performed to store the input information in a retrievable manner with associated attributes. As a result, the information in the information database DB1 can be searched for at least one of position information and attributes. Note that the information database DB1 can be updated.

The information providing unit 200d periodically or irregularly reads the information stored in the storage unit 202, that is, part or all of the information database DB1, and provides the terminal device 10 with the information. The information provided, that is, transmitted may be limited to predetermined information, such as only information within a predetermined range regarding the current location of the terminal device 10 . Also, the provision of such information from the server device 20 may be executed only when requested by the terminal device 10 .

FIG. 3 is a diagram showing an example of the monitor 14 of the terminal device 10. As shown in FIG. In FIG. 3, an input screen is displayed on the monitor 14 when the input unit 100c is in the operating state, the first area 14a is the tagging screen, the second area 14b is the information input screen, and the third area is the information input screen. 14c is an attribute selection area, and the fourth area 14d is a send button. A navigation screen or map information by the navigation section 100a is displayed in the first area 14a. In principle, the map information of a predetermined range including the position information of the terminal device 10 is displayed in the first area 14a, but the display area can be arbitrarily changed by the operation of the user or the like.

On the first area 14a of the monitor 14 of the terminal device 10, in principle, a tag MT indicating the current position is displayed. The tag MT may be the position of the terminal device 10 itself, but the position on the map can be changed by the operation of the user or the like. Note that the tag MT may also be called a virtual tag, a street tag, or a virtual street tag. However, in the first area 14a, the display of the tag MT and the display of the current position may be independent from the beginning.

In the second area 14b, the character input function of the monitor 14 allows the user to input information to be conveyed to a pedestrian or the like who may be a user of another terminal device 10 or the like. For example, when there is a large pothole in a pedestrian path, this is dangerous for pedestrians such as the physically handicapped, the visually impaired, and wheelchair users. When such information is desired to be conveyed to such pedestrians, the information is entered in the second area 14b. As a result, the input information, that is, the input information, is associated with the position information of the tag MT in the first area 14a as the position information related to the information.

In the third area 14c, it is possible to enter the attributes of the information entered in the second area 14b. Here, at least one attribute is selected from a plurality of attributes. FIG. 3 shows that "hazard" is selected as an attribute. Attributes can include, for example, "hazard", "advertisement", "message", and "share". The attribute “advertisement” can be attached to information (advertisement information) such as billboards virtually put out by retail stores, restaurants, and the like. An example of advertising information may be a "beer ad" on the beach. The attribute "message" can be attached to information (message information) intended to be conveyed to a specific party, especially only to the specific party. ” can be attached to the input information. In message information intended to be transmitted only to a specific party, the ID of the specific party, that is, the ID of the terminal device 10 of the specific party, etc., can be further input in the third area 14c or the like. In addition, in the system S, in order to use the service of the system S on each terminal device 10, it is necessary to perform user registration and login, and the ID information at this time is preferably used. Moreover, sex, age, etc. may be registered at the time of user registration, and the "sex" and "age" may also be used as attributes, for example. The attribute "shared" can be attached to information shared with any user, and is preferably information other than "hazard" information, but may also be attached to hazard information.

It should be noted that, as described above, when specifying the party to receive the information, the ID information of the terminal or user receiving the information can be input in the third area 14c as an attribute. In this case, this ID information should be an attribute of the input information.

By pressing the send button in the fourth area 14d, the information input in the second area 14b is transmitted to the server device 20 in association with the position information of the tag MT in the first area 14a. At this time, the attribute selected in the third area 14c is also attached to the information and transmitted. At this time, time information, such as the date and time when the send button was pressed, is preferably sent to the server device 20 together. Although the predetermined position information is the position information of the tag MT, it may be the current position information of the terminal device 10 when the send button is pressed, that is, when the input information is input.

The order of inputting this information will be described with reference to the flow chart of FIG.

At step S401, the position of the tag MT is designated. In other words, by designating the position of the tag MT on the first area 14a of the monitor 14 of the terminal device 10, the input acquisition section 100e can acquire the position information of the tag MT in cooperation with the navigation section 100a.

In step S<b>403 , information such as support information is input in the second area 14 b of the monitor 14 of the terminal device 10 . Then, in step S405, attributes are input in the third area 14c of the monitor 14 of the terminal device 10. FIG. Note that the order of steps S401 to S405 is not limited to this order, and may be in a different order, and may be repeated multiple times. By performing steps S401 to S405, the position of the tag MT is specified, only one position information is specified, and information such as support information and its attributes are input. As a result, the input acquisition unit 100e acquires and associates the position information of the tag MT in the first area 14a, the input information in the second area 14b, and the attribute information in the third area 14c. It should be noted that the information input by voice from the microphone 18 may be used instead of the input from the second area 14b and/or the third area 14c.

Then, in step S407, the send button is pressed. Accordingly, the transmission unit 100f transmits to the server apparatus 20 the input information in which the predetermined position information and the attribute are associated. Identification information in the registration information RI, for example, ID information such as a terminal ID or a user ID may also be attached to this transmitted information. At this time, the transmitting unit 100f may store the transmitted information in the storage unit 102 for a predetermined period of time, for example.

Information transmitted from the terminal device 10 is received and acquired by the server device 20 .

A flow from reception to storage of information in the server device 20 will be described with reference to the flowchart of FIG.

When the information transmitted from the terminal device 10 is received by the server device and is acquired by the information acquisition unit 200a, an affirmative determination is made in step S501. Note that step S501 is a step for determining whether or not information has been acquired, and is repeated until an affirmative determination is made.

In the next step S503, attributes of the acquired information are selected. That is, the attribute determination unit 200b determines the attribute of information based on the attribute database DB2. The attribute database DB2 is a database that defines the relationship between terms and attributes. For example, when the acquired information includes the term "restaurant", the "entertainment" attribute is selected. Also, for example, when the acquired information includes the term "dangerous" or the like, the attribute "hazard" is selected. As a result, hazard information can be preferably provided by the terminal device 10 possessed by a pedestrian such as a visually impaired person. In addition, in the terminal device 10, when the attribute of such information is already attached, it is preferable that the attribute is used as it is.

Then, in step S505, the storage execution unit 200c stores the acquired input information in the information database DB1 of the storage unit 202 so as to be searchable using position information, that is, position information of predetermined position information. At this time, the storage execution unit 200c stores the acquired information in the information database DB1 of the storage unit 202 so as to be searchable by attribute. It should be noted that this disclosure does not exclude that attributes may not be associated when storing information. Also, if identification information is attached to the transmitted information, the identification information may also be stored in association with the stored information.

On the other hand, pedestrian support and the like using the information thus stored will be described with reference to FIGS. 6 and 7. FIG.

FIG. 6 is a diagram showing an example of the monitor 14 of the terminal device 10. As shown in FIG. In FIG. 6, an output screen is displayed on the monitor 14 when the output unit 100d is in an operating state, and the A area 14e is a screen on which the tag MT and the current position CP of the terminal device 10 are displayed together. The B area 14f is an information output screen, the C area 14g is an input screen for attributes of information desired by the user, and the D area 14h is a screen that is turned ON from OFF when audio output is desired.

The A area 14e corresponds to the first area 14a, and displays map information, and also displays a tag MT superimposed on the information database DB1 with predetermined positional information associated with the input information as the positional information of the position. be done. Information associated with the tag MT is displayed in the B area 14f. The display of the tag MT and the display of the input information are performed by the extraction of the input information by the information extraction unit 100g, the attribute determination by the attribute determination unit 100h based on the attribute of the C region 14g for the information, and the output by the display output unit 100j. executed.

When the audio output is ON in the D area 14h, the audio output unit 100j outputs the information to be output to the B area 14f as audio from the speaker 16 at a predetermined time. The predetermined time is when the current position CP is moving toward the tag MT in the A region 14e, and the distance between the position of the tag MT (the position of the predetermined position information) and the current position CP is a predetermined distance or It is good to include the time when it becomes less than that.

The order of outputting this information will be described with reference to the flow chart of FIG.

In step S701, the position information of the current position of the terminal device 10 is acquired. Here, position information is acquired by the position information receiving unit 12 .

In step S703, it is determined whether or not there is information having a predetermined relationship with the position information of the current position of the terminal device 10 acquired in step S701. Specifically, it is determined whether or not the information database DB1 contains input information having predetermined position information that defines a position within a predetermined range from the current position of the terminal device 10 . An affirmative determination is made when there is input information, and a negative determination is made when there is no input information, and the process returns to step S701. Steps S701 and S703 are performed by the information extraction unit 100g.

When there is information (affirmative determination in step S703), the attribute of the information is determined in step S705. This attribute determination is performed by the attribute determination unit 100h based on the attribute of the C region 14g. Then, when the attribute of the information matches the attribute of the C area 14g, an affirmative determination is made in step S705. When the attributes do not match (negative determination in step S705), the process returns to step S701. It should be noted that input information with the attribute "shared" may be affirmatively determined in step S705 regardless of whether the attributes match. In addition, regarding the input information with the attribute "hazard", affirmative determination may be made in step S705 regardless of whether the attributes match. This is to contribute to the safety of users who may be pedestrians or the like.

Then, when an affirmative determination is made in step S705, the extracted information, for example, the display of the tag MT and the support information are output to the A area 14e and the B area 14f. This output is performed by the display output unit 100i.

Furthermore, in step S709, it is determined whether or not the voice output button for requesting voice output in the D area 14h is in the ON state. Then, when an affirmative determination is made in step S709, the input information associated with the tag MT within a predetermined distance from the current position CP is output as voice at a predetermined time by the voice output unit 100j in step S711.

Note that when voice output is not desired (negative determination in step S709) or after step S711, the routine ends and returns to step S701 of the next routine.

According to the system S configured as described above, firstly, a user who has actually arrived at the spot, for example, a pedestrian, inputs input information with the terminal device 10 possessed by the user, and uses the information database of the server device 20 or the like. It can be stored in DB1. Secondly, information stored by other users or information stored by the user himself/herself in the past, especially hazard information, can be used by a user possessing the terminal device 10, for example, when the information is needed. Pedestrians can be acquired more conveniently. Therefore, for example, it is possible to more preferably inform the pedestrian of the condition of the road on which the pedestrian is walking. In this way, according to the system S, it is possible to appropriately convey the information on which a person who has reached a certain place first pays attention to another person who has subsequently reached that place.

It should be noted that the terminal device 10 is not limited to a device that is held by a pedestrian's hand, and may be a device that is detachably provided on or around the face of the pedestrian. The terminal device 10 may be, for example, a terminal device that includes a speaker and a microphone and can be worn around the neck of a pedestrian who is a user. Also in this case, the terminal device should preferably have the same configuration as the terminal device 10, and in particular, should include an audio output unit 100j for outputting audio.

Although the system S according to the above-described embodiment is mainly intended for assisting walking of pedestrians, particularly assisting walking of handicapped persons such as visually impaired persons, it may be used in other scenes. For example, the system S can be used when a retail store, restaurant, or the like puts out a virtual signboard and wants people who come to a predetermined place (for example, within a predetermined range of the store) to see the signboard. An example of information is "There is an Italian restaurant xxx just around the corner. The lunch menu is a bargain at xxx yen!". At this time, it is preferable that the information is input by the store-side terminal device and the information is output by the customer-side terminal device. Also, for example, the system S may be used when it is desired to convey information to a specific party, particularly only to that specific party. For example, it is possible to input input information such as "I will not come at the meeting time, so I will go home." can be done. In this case, regardless of the attribute input in the C region 14g of the terminal device 10 on the information receiving side, the attribute determination unit 100h determines whether the ID information associated with the input information matches the ID information of the terminal, for example. It is determined whether or not (step S705). Further, for example, the system S is available for information that is desired to be shared with any user. For example, it is possible to share information such as "What time is the best time to see the scenery from here?", "Flowers are blooming on the roadside, so don't step on them."

As described above, various attributes may be used for both input information and output information. For example, as described above, gender, age, etc. at the time of user registration can also be used as attributes. Furthermore, the expiration date of the information may be designated by minutes, hours, days, months, or the like. As a result, input and output (providing) of construction information can also be performed as input and output of information of the attribute "hazard", for example. Furthermore, the form of notification of information is not limited to text and/or voice, and may be a combination of at least two of voice, text, image, and the like.

Although the embodiments and modifications thereof according to the present invention have been described above, the present invention is not limited thereto. Various substitutions and modifications may be made without departing from the spirit and scope of the invention as defined by the claims of this application.
