Referring to FIG. 2 , a visually impaired person walking inside a subway station needs to be informed of the existence of a pillar when a pillar exists in the direction of travel. Accordingly, the structure terminal 201 installed on the pillar of FIG. 2 transmits structure information data to the user terminal 301 through the communication network 401 . The user terminal 301 receiving the structure information data considers that the type of structure is a pillar, and when the distance between the structure and the user terminal 200 becomes d or less, tactile a structure guide signal informing the user that there is a pillar nearby converted to a signal and output.

Hereinafter, the internal/external structure of the user terminal 301 and its role will be examined in more detail.

3 is a block diagram showing the configuration of a user terminal 301 according to an embodiment of the present invention.

Referring to FIG. 3 , a user terminal 301 according to an embodiment of the present invention includes a data receiving unit 310 , a data conversion unit 320 and an output unit 330 . In addition, the data conversion unit 320 includes a structure type determination unit 321, a distance calculation unit 322, a guide signal generation unit 323, an abnormal situation detection unit 324, and an output signal conversion unit 325. .

First, the data receiver 310 according to an embodiment of the present invention receives structure information data from the structure terminal 201 through the communication network 401 . The data receiving unit 310 may be a receiving device using the protocol of the communication network 401 . For reference, the data receiving unit 310 according to an embodiment of the present invention may further include a communication interface. The communication interface may be an interface including hardware and software necessary for transmitting and receiving a signal such as a control signal or a data signal through a wired or wireless connection.

Next, the data converter 320 generates a structure guide signal based on the structure information data from the data receiver 310 and converts it into an output control signal, and the output unit 330 outputs the output control signal as a tactile signal do.

In more detail, the structure type determination unit 321 of the data conversion unit 320 determines the type of structure in which the structure terminal 201 is installed based on the received structure information data. At this time, as described above, the type of structure may be all types of structures that need attention when the blind pass through. As a specific example, when the space of the present invention is a subway station as in the above example, the structure type of the space may be a pillar, a staircase, a ticket gate, a wall, a boundary between a platform and a track, and the like.

Next, the distance calculating unit 322 calculates the distance between the structure where the structure terminal 201 is installed and the user terminal 301 based on the obtained structure information data. According to an embodiment of the present invention, the distance calculation unit 322 analyzes the transmission time included in the structure information data and the reception time received by the data receiving unit 310 of the user terminal 301 to determine the structure and the user terminal 301. ) can be calculated. A method of calculating the distance between the structure and the user terminal 301 by the distance calculation unit 322 is not limited to the above example, and various embodiments of the distance measuring method may be applied.

According to an embodiment of the present invention, the structure terminal 400 using the communication network 401 may have different coverage ranges capable of detecting and communicating with the user terminal 200 according to the characteristics of the local area network 401. . In addition, even if the user terminal 301 can enter the coverage range of the structure terminal 201 and receive structure information data, the structure may not be close enough for the user to receive a notification. Therefore, according to an embodiment of the present invention, when the distance between the structure and the user terminal 301 is less than or equal to a predetermined value, a signal for guiding this is generated. To this end, there is a need to calculate the distance between the structure and the user terminal 301 based on the structure information data.

Next, the guide signal generation unit 323 considers the type of structure determined by the structure type determination unit 321 and determines that the distance between the structure calculated by the distance calculation unit 322 and the user terminal 301 is equal to or less than a predetermined value. When it is, it is possible to generate a structure guidance signal. In this case, the structure guide signal may include information about the existence of a structure or the type of structure. Alternatively, the structure guide signal may additionally include information on a subsequent action to be taken by the user according to the type of structure.

As a more specific example, when the type of structure is a pillar and the distance between the structure and the user terminal 301 is 5 m or less, the guide signal generating unit 323 generates a guide signal notifying that a pillar exists in the user's movement direction. can Such a guide signal may be output in braille meaning a pillar from the output unit 330 of the user terminal 301 or may be output in various types of tactile signals, such as a preset haptic signal. The guide signal generating unit 323 may generate a guide signal that further includes additional information, such as a distance between a structure and the user terminal 301, in addition to notifying the type of pillar.

As another specific example, when the type of structure is a dead-end wall and the distance between the structure and the user terminal 301 is 5 m or less, since the user needs to change the walking direction, the structure guide signal is sent to the follow-up action to change the walking direction. information may be included. Similarly, such a guide signal may be output in Braille indicating a walking direction change from the output unit 330 of the user terminal 301 or may be output as a preset haptic signal.

In addition, the guidance signal generation unit 323 may determine a predetermined value for a distance to generate a structure guidance signal in consideration of the moving speed of the user terminal 301 . As a specific example, when the moving speed of the user terminal 301 is fast compared to a preset standard, a structure guide signal is generated when the distance from the structure is 7 m or less, and when the distance to the structure is 3 m or less when the moving speed of the user terminal 301 is slow, the structure A guide signal can be generated.

In addition, the structure guide signal according to an embodiment of the present invention may be a signal that flickers with a certain frequency, and the frequency increases as the distance between the structure and the user terminal becomes closer. For example, when the structure guide signal generated by the guide signal generator 323 is converted into an output control signal and is a signal that causes the protrusions of the output unit 330 to move up and down, the guide signal generator 323 generates a structure A structure guidance signal may be generated so that the protrusions move up and down with a certain frequency according to the distance between the terminal and the user terminal 301 . At this time, if the frequency at which the protrusions move up and down increases as the distance between the structure and the user terminal 301 decreases according to an embodiment of the present invention, the user can grasp the distance from the structure by the tactile signal without additional information. can

Next, the abnormal situation detection unit 324 serves to determine whether an abnormal situation has occurred to the user. The abnormal situation refers to a situation in which the user unintentionally loses the direction of travel, such as when the user suddenly falls down or bumps into something. The abnormal situation detection unit 324 determines whether an abnormal situation has occurred by detecting whether there is a change in direction or position of the user terminal 301 greater than or equal to a threshold value for a predetermined period of time. When the abnormal situation detecting unit 324 determines that an abnormal situation has occurred to the user, the structure guidance signal generated by the guidance signal generating unit 323 goes beyond notifying the existence of a structure and provides information for guiding the direction of the structure. may additionally be included.

In the case of blind people, if they fall unintentionally, they have difficulty getting up and recognizing the direction. In addition, according to an embodiment of the present invention, even if the user is informed that a structure exists nearby while moving, the user loses the direction in which he was moving when he gets up when he falls, so when he moves in any direction, the corresponding structure is close. It's hard to know if you're losing Therefore, according to an embodiment of the present invention, when the abnormal situation detecting unit 324 detects an abnormal situation when the distance between the structure and the user terminal is less than or equal to the predetermined distance, the structure guide signal is used to inform the existence of the structure. Subsequently, information for guiding the direction of the structure may be included. Thus, according to one embodiment of the present invention, even if a visually impaired person falls and loses, he or she can be guided to the direction of the structure in addition to the previously provided structure guidance data, so that even if the user unexpectedly loses the direction, the user can guide the user to the structure. location can be easily identified.

In a specific embodiment, projections of the output unit 330, which will be described later, may generate Braille characters representing 'pillars' according to a structure guidance signal. In addition, when an abnormal situation is detected by the user after the braille indicating 'column' continues for a certain period of time, braille indicating that the structure is located in the left direction from the location of the user terminal may be additionally output.

Next, the output signal conversion unit 325 may convert the generated structure guide signal into an output control signal that can be output from the output unit 330 of the user terminal 301 . That is, the output signal conversion unit 325 may convert the structure guide signal into an output control signal that the output unit 330 can interpret. When the user terminal 301 outputs information through the vertical movement of the projections, the output signal conversion unit 325 may control the output signal so that the projections are controlled to correspond to the output data. When the user terminal 301 outputs information through vibration, the output signal conversion unit 325 may generate an output control signal so that vibration corresponding to the output data can be generated. When the user terminal 301 outputs information through nerves or cells, the conversion unit 150 may generate an output control signal so that stimulation and sensation corresponding to the output data may be generated. The output signal conversion unit 325 may generate an output control signal that can be directly transmitted to the user's brain nerves and brain cells, or may generate an output control signal that can be directly transmitted to nerves or cells capable of detecting other senses. may be The form, form, and format of the output control signal generated by the output signal conversion unit 325 varies depending on the transmission method, method, and algorithm.

Next, the output unit 330 of the user terminal 301 is a device controlled by an output control signal to deliver a tactile signal to the user. In more detail, the output unit 330 may directly contact the user or deliver data to the user in a non-contact manner. The output unit 330 may be any type of output device capable of transmitting a tactile signal such as a braille projection signal or a haptic signal to a user.

According to a more specific embodiment of the present invention, the output unit 330 may transmit data to the user through one or more projections. Each protrusion can give a one-dimensional point-like stimulus to the user by linearly moving in an up-and-down direction, or give a two-dimensional line-like stimulus to the user by linearly moving in a left-right direction. In addition, the plurality of protrusions may simultaneously or sequentially hit the user, thereby generating stimuli corresponding to actions in the real world and actions in the virtual world. The output control signal may include a direction in which one or more protrusions move, a moving time point, and a duration for controlling the motion of the protrusion.

At this time, the output unit 330 is disposed at a position corresponding to the user's nerves, cells, or blood vessels, and can transmit data through the user's nerves, cells, or blood vessels, and the output unit 330 can be felt by the user through the nerves. stimuli, and/or signals that are present. In addition, the one or more information output units 330 may be connected to the user's brain and transmit data that can be understood through the user's brain.

As described above, the user terminal 301 may include the output unit 330 provided in a portion of the user terminal, and according to an embodiment of the present invention, the output unit 330 has an expression surface facing the user. It may include protrusions 30n provided to be positioned. Therefore, the protrusion signal by the selective entry and exit of the protrusions 30n that appear on the expression surface can be recognized as a direct and local hit to the user, and the user can directly perceive the hit at the position hit by the protrusions 30n. vibration can be received. Unlike general vibration signals of portable electronic devices, the salient signal formed by such a direct and local impact does not cause residual vibration to occur around the target, so an accurate signal can be delivered to the user. Accordingly, signals acquired through the tactile sense, such as Braille, can be implemented by the protruding signal as described above, and various signals such as military signals, picture signals, code signals, and direction signals can be accurately implemented. That is, the expression surface of the user terminal 301 shown in FIG. 4 is positioned so as to be in contact with the user's skin.

Additionally, the user terminal 301 may include a vibration motor for controlling selective access of the protrusions 30n.

Referring to FIG. 7 , it can be seen that the space guidance system is composed of a server 100 , a structure terminal 202 , a user terminal 302 and a communication network 402 . Since the embodiment shown in FIG. 7 is a modified example of the first embodiment of the present invention described in FIGS. 1 to 6 , hereinafter, differences in the first embodiment will be mainly described.

In the second embodiment according to an embodiment of the present invention, the structure terminal 202 installed in the structure of the space detects the approach of the user terminal 302 to generate an approach detection signal, and transmits the generated proximity detection signal to the server ( 100). At this time, the approach detection signal may include information about the structure terminal 202 transmitting the signal, a structure in which the structure terminal 202 is installed, and information about the detected user terminal 302 . In addition, the structure terminal 202 detecting the approach of the user terminal 302 may follow the method described in the above-described first embodiment.

Next, the server 100 receiving the approach detection signal from the structure terminal 202 generates structure information data by extracting structure terminal information from the approach detection signal. When the space guidance system according to an embodiment of the present invention is initially constructed, information on a corresponding structure may be stored in the structure terminal 202 installed in the structure. Therefore, as described above, the structure terminal 202 may include information on the structure terminal and the structure in the proximity detection signal, and the server 100 may extract structure terminal information from the proximity detection signal. Additionally, the server 100 may extract user terminal information of the user terminal 302 approaching the structure terminal 202 from the approach detection signal.

The server 100 may generate structure information data using the extracted structure terminal information. The structure information data generated by the server 100 may include the same information as the structure information data generated by the structure terminal 201 described above in the first embodiment. In addition, the server 100 transmits the generated structure information data to the user terminal 302 by referring to the extracted user terminal information.

The operation of the user terminal 302 receiving the structure information data can be applied as it is after modifying the operation of the user terminal 301 of the first embodiment to be suitable for the second embodiment. For example, the user terminal 302 includes a data conversion unit, and the data conversion unit analyzes the structure information data received from the server 100 to generate a structure guidance signal, converts the structure guidance signal into an output control signal, and outputs the output control signal. It can be printed from the In addition, the functions of each component of the user terminal 301 described in the first embodiment may be modified to suit the second user terminal 302 of the second embodiment. For example, the user terminal 302 may continuously receive structure information data from the server 100 at short time intervals in order to calculate the distance between the structure and the user terminal 302 . In this case, the structure information data may include a distance between the structure calculated from the approach detection data and the user terminal 302 .

The communication network 402 used for communication between the server 100, the structure terminal 202, and the user terminal 302 may be any type of wireless communication network that provides an access path to transmit and receive packet data. That is, the communication network 402 of the second embodiment of the present invention may include all known data communication networks without necessarily being limited to a local area wireless communication network.

Meanwhile, in a modified embodiment of the above-described second embodiment of the present invention, some functions of the user terminal 302 may be implemented in the server 100 . For example, instead of determining the type of structure in the structure type determining unit of the user terminal 302, the server 100 may determine the type of structure and include the information in the structure information data. More specifically, in a modified embodiment of the second embodiment according to an embodiment of the present invention, some of the functions performed by the data conversion unit of the user terminal 302 may be performed by the server 100 instead.

When the structure information data is transmitted from the server 100 to the user terminal 302 instead of the structure terminal 202 directly transmitting the structure information data to the user terminal 302 as in the second embodiment of the present invention, the structure terminal (202) can reduce the burden on the individual structure terminal (202) because only the approach detection data needs to be transmitted to the server (100). In addition, since the server 100 can know the approximate location of the current user terminal 301 by utilizing the information of the structure terminal 202, when analyzing a plurality of proximity detection data, the path of the user terminal 302 can be known. have beneficial effects.
