Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for recognizing a movement direction of a user,

The present invention relates to a technique for providing a user movement direction recognition system and method, as well as providing personalized information based thereon.

As smartphones become more popular, O2O (Online to Offline) service is being activated to provide customized information according to the situation by linking online and offline. The core of the O2O service is to find out the location of the user. Recently, a location recognition technology using a BLE (Bluetooth Low Energy) beacon is widely used.

Conventionally, as an example of a service using a beacon, in a case where a beacon is installed in each off-line store, when a user passes a peripheral area of a specific store, a received signal strength (RSSI, There is a technique of calculating a distance between the beacon and the user terminal based on the distance, and then providing a service such as a discount coupon or an advertisement message based on the distance.

Here, the beacon signal can reach a wide range from about 50 m to 70 m, which is a conventional beacon-based service. The beacon signal generated from this one beacon is divided into four types (Generally, an Immediate distance up to about 20 cm, a Near distance up to about 2 m to 3 m, a Far distance up to about 50 m to 70 m, and an Unknown distance when a signal can be detected but a distance can not be specified) The distance between one beacon and the user terminal is calculated.

According to the beacon specification, a beacon can not be used to determine the exact distance between a beacon and a user terminal. Therefore, there is a problem in that the existing method for determining the precise position of the user, such as triangulation, can not be used by using the beacon and the existing method of determining the direction of the user using the precise position of the user can not be used.

In addition, when a beacon is installed in each off-line store as in the prior art, since one beacon and another beacon are separated by a considerable distance (approximately several tens of meters or more) It is only possible to roughly determine the moving direction in the wide area (for example, moving from the first store to the second store in the direction in which the second store is located) only when passing the boundary of the distances separated by the branches, There has been a problem that, for example, a user who passes a specific spot in an area where a signal is detected (for example, an area within the Far distance range) can not accurately grasp the direction in which the user moves.

The background technology of the present application is disclosed in Korean Patent Laid-Open Publication No. 10-2016-0043879 (published on May 20, 2014).

1 is a schematic block diagram of a user movement direction recognition system according to an embodiment of the present invention.

Referring to FIG. 1, a user movement direction recognition system 100 according to an embodiment of the present invention may include a reception unit 110 and a movement direction determination unit 120.

The user movement direction recognition system 100 according to an exemplary embodiment of the present invention may be included in a user terminal or may be a system separate from the user terminal (for example, a server as a customized information providing system to be described later) . ≪ / RTI > Hereinafter, the case where the user movement direction recognition system 100 is included in a user terminal will be described as an example. Accordingly, the user movement direction recognition system 100 can be performed by a user terminal. When the user movement direction recognition system 100 is included in a server (for example, a customized information providing system to be described later) which is a system separate from the user terminal as described above, .

The receiving unit 110 may receive the signal strength information according to the movement of the user terminal sensed from the first beacon unit and the second beacon unit, which are spaced apart at a predetermined interval. This can be more easily understood from Fig.

2 is a diagram illustrating an example of installation of a pair of beacon units used in the user movement direction recognition system 100 according to an embodiment of the present invention.

Referring to FIG. 2, a pair of beacons 1 and 2 applied to the user movement direction recognition system 100 according to an embodiment of the present invention includes a first beacon unit 1 and a second beacon unit 2, And the first beacon portion 1 and the second beacon portion 2 may be spaced apart from each other by a predetermined distance r1.

Here, the predetermined interval r1 means an interval spaced apart from each other in a parallel direction corresponding to a user's movement line (or movement path) in the space where the first beacon portion 1 and the second beacon portion 2 are arranged can do. For example, when the space in which the pair of beacons 1 and 2 are arranged is a general hallway or the like having a horizontal movement path, the first beacon portion 1 and the second beacon portion 2 are arranged in the same manner as the hallway And may be spaced apart in a direction parallel to the horizontal movement path. In the example of Fig. 2, the first beacon unit 1 and the second beacon unit 2 are provided on a wall surface of a corridor or the like, and the first beacon unit 1 and the second beacon unit 2, In addition, it can be arranged in various spaces (places) for sensing the moving direction of a user such as an alley, a bridge, a subway, and the like. The predetermined interval r1 may be an interval within an error range of the distance between the user terminal 10 and the beacons 1 and 2 calculated based on the signal strength of the beacons 1 and 2. [

As described above, the beacon greatly divides the area (distance range) into Immediate, Near, Far, and Unknown according to the signal strength. For example, in the Far area, accurate calculation of the distance is difficult. The beacons (1, 2) of the present invention can be provided within the error range of the distance calculation to provide a user movement direction recognition system which can accurately determine the direction of movement even when accurate distance determination or movement direction determination is difficult. By arranging the pair of beacons 1 and 2 within a few meters, it is possible to clearly detect the direction of movement of the pair of beacons 1 and 2 at a specific spot. Conventionally, since a plurality of beacons are arranged at intervals of several tens of meters, the user can only estimate a copper wire once the user has traveled for several tens of meters. However, according to the present invention, the direction of travel at a specific spot is close to real time or real time It has the advantage of being able to do.

The pair of beacons 1 and 2 may be spaced apart from each other by a predetermined distance r1 within a few meters to be able to accurately determine the moving direction of the user. May be 2.4 m, but is not limited thereto. The beacons 1 and 2 may be BLE (Bluetooth Low Energy) beacons, but are not limited thereto.

Between the first beacon unit 1 and the second beacon unit 2, an information providing apparatus 20 capable of displaying customized information provided by a customized information providing system to be described later may be disposed. For example, the information providing apparatus 20 may be a digital signage, but not limited thereto, may include all devices capable of displaying information.

The user terminal 10 is a mobile communication device which is guaranteed to be portable and mobility and can be used as a mobile communication device such as a PCS (Personal Communication System), a GSM (Global System for Mobile communication), a PDC (Personal Digital Cellular) , PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication) -2000, CDMA (Code Division Multiple Access) -2000, W-CDMA (WCode Division Multiple Access), Wibro (Wireless Broadband Internet) , A SmartPad, a tablet PC, a notebook, a wearable device, and the like.

The moving direction determination unit 120 determines the first coincidence time signal intensity information and the second coincidence time information that are detected during the same time period among the signal intensity information of the first beacon unit 1 and the signal intensity information of the second beacon unit 2, The direction of movement of the user can be determined by comparing the signal strength information with each other. This can be more easily understood with reference to FIG.

3 is a diagram illustrating an example of signal strength information according to movement of the user terminal 10 in the user movement direction recognition system 100 according to an embodiment of the present invention.

3, the user terminal 10 includes a first beacon unit 1 and a second beacon unit 2 in a state where the first beacon unit 1 and the second beacon unit 2 are disposed at a predetermined interval, The first beacon portion 1 and the second beacon portion 2 are assumed to move in the direction of the position where the second beacon portion 2 is disposed (for example, from left to right in the drawing of Fig. 3) (Received Signal Strength Indicator) between each user terminal 10 and each of the mobile stations 10 and 20.

Specifically, the graph S1 is a graph of a change in an ideal beacon signal intensity according to a distance between the user terminal 10 and the first beacon portion 1 sensed by the user terminal 10 when the user terminal 10 is moved, The graph of S2 indicates the distance between the user terminal 10 and the second beacon portion 2 sensed by the user terminal 10 during the movement of the user terminal 10. [ And the signal strength information of the second beacon unit 2 is expressed differently. Ideally, as shown in the graph of FIG. 3, as the distance between the user terminal 10 and the beacons 1 and 2 approaches, the signal strength RSSI becomes stronger and the user terminal 10 and the beacons 1, As the distance increases, the signal strength will become weaker. However, in reality, as the beacon signal is affected by various factors such as the surrounding environment, there may be an error in the measured value of the signal intensity generated from the beacons 1 and 2 measured by the user terminal 10. This will be described later in more detail.

On the other hand, in general, it has been reported that the beacon signal reaches an ideal of about 70 m and reaches about 50 m in a normal environment. Considering that the first beacon unit 1 and the second beacon unit 2 are arranged at a predetermined interval r1 in consideration of the maximum transmission distance of the beacon signal, The user terminal 10 first senses only the signal S1a generated from the first beacon unit 1 for a predetermined time and then outputs the signal S1a generated from the first beacon unit 1 1) and a signal generated from the second beacon unit (2), detects only a signal generated from the second beacon unit (2) for a predetermined time, The first beacon unit 1 and the second beacon unit 2 will not be able to detect all signals.

In this case, the movement direction determination unit 120 according to an exemplary embodiment of the present invention determines the direction of movement of the user based on the signal intensity information S1 and S2 sensed from the first beacon unit 1 and the second beacon unit 2, The signal intensity information S1 detected during the same time range t _same among the signal intensity information S1 of the first beacon portion 1 and the signal intensity information S2 of the second beacon portion 2, It is possible to determine the moving direction of the user by using only the slits S1b and S2b. Here, the same time range ( _t.sub.ame ) refers to a time range during which the signal intensity information S1 of the first beacon portion 1 and the signal intensity information S2 of the second beacon portion 2 are simultaneously detected. It may mean a time range considered in determining the moving direction. Of the signal strength information S1b and S2b sensed during the same time range, S1b may be information detected from the first beacon unit 1 as the first coincident signal strength information, and S2b may be the second beacon unit 2) as the second same-time signal intensity information.

More specifically, the moving direction determination unit 120 determines a point A at which the signal intensity information S1 of the first beacon unit 1 and the signal intensity information S2 of the second beacon unit 2 are simultaneously detected It can be recognized as the start time of the time range (t _same ). The moving direction determining unit 120 determines whether the user terminal 10 has reached the predetermined distance r2 from the first beacon unit 1 or the second beacon unit 2 (B) can be recognized as the end time of the same time range (t _same ). Here, A point refers to the start time of the same time range (t _same) are considered in determining the user's direction of movement, and B the time refers to the end of the same time range (t _same) are considered in determining the user's direction of movement can do.

3, the display of the starting time point A and the ending time point B of the same time range t _same and the display of the predetermined distance r2 are displayed on the basis of the first beacon unit 1 as a reference However, the present invention is not limited to this, and the same logic can be applied to the case where the second beacon unit 2 is used as a reference. That is, this logic is based on the fact that the user terminal 10 moves through the second beacon portion 2 in the direction of the position where the first beacon portion 1 is disposed (for example, from the right to the left in the drawing of Fig. 3) The present invention is applicable to the same case.

The first beacon portion 1 and the second beacon portion 2 may have a predetermined distance r2 that is a reference to the end time B of the same time range t _same according to an embodiment of the present invention. The predetermined distance r2 may be a distance defined between the first beacon portion 1 and the second beacon portion 2 according to another embodiment of the present invention, The information providing device 20 may be a distance defined based on the information providing device 20 disposed in the mobile communication terminal. For example, the predetermined distance r2 may be a radius of 3 m.

The moving direction determination unit 120 may determine a first determination value and a second same time signal intensity information S2b based on the accumulated value of the first coincidence signal strength information Sb according to the time during the same time range t _same , The second determination value based on the cumulative value of the user can be determined to determine the moving direction of the user. Here, the first judgment value means an average value of the cumulative value of the first coincidence time signal strength information S 1 b and the second judgment value may mean the mean value of the cumulative value of the second coincidence time signal strength information S 2 b have. However, the first judgment value and the second judgment value are not limited to this but may mean the cumulative value itself.

Also, the moving direction determination unit 120 may determine a small value at a position of the beacon corresponding to a determination value having a larger one of the first determination value and the second determination value, as a result of mutual comparison of the first determination value and the second determination value It can be determined that the user moves in the direction toward the position of the beacon corresponding to the judgment value. For example, when it is determined that the first average value is larger than the second average value, the movement direction determination unit 120 determines that the first beacon unit 1 corresponding to the first average value corresponds to the second average value It is possible to determine that the user moves in the direction to the position where the second beacon unit 2 is disposed (i.e., from left to right as shown in FIG. 2).

Specifically, the movement direction determination unit 120 determines whether or not the cumulative value of the RSSI values sensed from the first beacon unit 1 during the same time range t _same , that is, the first coincidence time signal strength information S1b, (Hereinafter, referred to as a first average value) of the cumulative value calculated after calculating the cumulative value of the cumulative value of the cumulative value. In addition, the movement direction determination unit 120 determines whether or not the cumulative value of the RSSI values detected from the second beacon unit 2 during the same time range t _same , i.e., the cumulative value of the second same time signal intensity information S2b (Hereinafter referred to as " second average value ") of the cumulative value calculated after the value is calculated. Then, the movement direction determination unit 120 may determine that the user moves from the position of the beacon unit having the larger average value to the position of the beacon unit having the smaller average value through the mutual contrast between the first average value and the second mean value . The reason why the moving direction determination unit 120 according to the embodiment of the present invention uses the accumulated value of the signal strength (RSSI) value or the average value of the accumulated value when determining the moving direction of the user is more easily understood with reference to FIG. 4 .

4 is a diagram illustrating signal intensity values measured from a pair of beacons during the same time range in the user movement direction recognition system according to an embodiment of the present invention. In other words, FIG. 4 shows the first coincidence time signal strength information S 1 b and the second coincidence time signal strength information S 2 b (FIG. 3) measured in time during the same time range t _same , for example, ).

4, ideally, because the user terminal 10 is positioned closer to the first beacon portion 1 than the second beacon portion 2, 2 time-signal strength measurement value (S2b), it is normal that the first same-time signal strength measurement value (S1b) and the second same-time signal strength measurement value (S2b) (That is, when the second coincident time signal strength measurement value S2b is measured to be larger than the first coincidence time signal strength measurement value S1b) exists. According to this, it is not possible to accurately determine the moving direction of the user only by comparing the signal intensity values measured at each moment from the two beacons 1 and 2. [

Therefore, the movement direction determination unit 120 according to the embodiment of the present invention determines the direction of movement of the beacon units 1 and 2 based on the signal intensity detected from the first beacon unit 1, Is not stronger than the signal intensity detected from the second beacon unit 2, and instead of comparing only the signal intensity (RSSI) value measured every moment, the average value The moving direction of the user can be accurately determined.

The moving direction determination unit 120 determines the moving direction of the user based on the first coincident time signal strength information S 1 b and the second coincidence time signal strength information S b at the same time point within the same time range t _same S2b are not detected (or missing), information detected at the same point in time that the unrecognized information exists among the first coincidence time signal strength information (S1b) and the second coincidence time signal strength information (S2b) Can be excluded when calculating the cumulative value. This can be more easily understood with reference to FIG.

5 is a diagram illustrating a case where a measured value among measured values of signal intensities sensed from a pair of beacons in a user movement direction recognition system according to an exemplary embodiment of the present invention is missing. In other words, FIG. 5 illustrates the first coincidence time signal strength information S 1 b and the second coincidence time signal strength information S 2 b measured over time during the same time range t _same , for example, In more detail, an example of a value obtained by measuring the signal strength (RSSI) value of a signal generated from a pair of beacons 1 and 2 at intervals of 1 second while the user terminal 10 actually moves FIG.

5, ideally, the user terminal 10 should detect the signal intensity values of the first beacon portion 1 and the second beacon portion 2 every second, but in the actual information, the beacon signal It can be confirmed that some signal strength values are missing due to the influence of the surrounding environment. Specifically, only the signal intensity value of the first beacon portion 1 is detected at 1 second, 2 seconds, and 14 seconds, and the signal intensity values of the two beacons 1 and 2 are not detected for 3 to 7 seconds , Only the signal intensity value of the second beacon unit 2 is sensed for 8 to 10 seconds and that the signal intensity values of the two beacons 1 and 2 are sensed for 11 to 13 seconds.

At this time, if the signal strength values of the first beacon unit 1 and the second beacon unit 2 are not detected (that is, all of them are missing) or only one of them is detected, The signal strength value detected at the time point can be excluded when calculating the cumulative value for determining the moving direction. In other words, the moving direction determination unit 120 considers the value only when the signal intensity values of the first beacon unit 1 and the second beacon unit 2 are detected in the calculation of the cumulative value for determining the moving direction . That is, the moving direction determination unit 120 excludes the beacon signal intensity values sensed at 1 second to 10 seconds and 14th seconds in the cumulative value calculation, and the signal intensity values of the beacons sensed at 11 to 13 seconds are accumulated Can be considered when calculating the value. The movement direction determination unit 120 calculates an average value of the accumulated values of the signal intensity values for the first beacon unit 1 and the second beacon unit 2, can do.

Meanwhile, the first beacon unit 1 and the second beacon unit 2 may be arranged in a pair in correspondence with the movement direction to be determined, and may be given the same identification number (differently, a common service number) . Then, the movement direction determination unit 120 determines a movement direction based on the accumulated value of the same time signal strength information (S1b, S2b) received from each of the first beacon unit 1 and the second beacon unit 2 having the same identification number The direction of movement can be determined through mutual contrast between the two.

The moving direction determination unit 120 may determine the moving direction based on the information stored in the database (not shown). In the database, a first beacon unit 1 and a second beacon unit In addition to the information about the same identification number assigned to the other beacon pairs, an identification number assigned to the other plurality of beacon pairs, and the like may be stored. In addition to the identification number of the pair of beacons 1 and 2, information on the information providing apparatus 20 associated therewith may be stored together in the database.

Specifically, in order to determine whether or not the user is moving to a pair of beacon units 1 and 2 disposed in a specific area, the same identification number may be given to the pair of beacon units 1 and 2, The pair of beacons different from the pair of beacons 1 and 2 may be given the same identification number different from the identification number given to the pair of beacons 1 and 2 .

According to an embodiment of the present invention, the receiving unit 110 and the moving direction determining unit 120 are provided in the user terminal 10, the database (not shown) is provided in a server separate from the user terminal 10 . According to another embodiment of the present invention, the receiving unit 110, the moving direction determining unit 120, and a database (not shown) may all be provided in the server.

In the user movement direction recognition system 100 according to the embodiment of the present invention, the information providing apparatus 20 disposed between a pair of beacons 1 and 2 and a pair of beacons 1 and 2 includes a set and may be provided as a service apparatus of a set. At this time, the service apparatus constituting such a set may be provided in each of the areas requiring judgment of the moving direction in a space such as the history of the subway. That is, a plurality of service apparatuses may be provided, and each of the plurality of service apparatuses may be provided with the same service, or different services may be provided. For example, when a plurality of service apparatuses are applied to a plurality of digital signage arranged along a wall of a subway station, the same service may be provided for each of the signage screens, or a different service may be provided. Thus, in the user movement direction recognition system 100 according to the embodiment of the present invention, scalability and flexibility in operation of the apparatus, such as increasing the number of service apparatuses as necessary, can be ensured.

When the beacon signal is received from two beacons, the movement direction determination unit 120 can confirm whether each of the beacons received from the two beacons has the same identification number (differently, a common service number). When the received beacon signal has the same identification number, the movement direction determination unit 120 determines the accumulated value of the signal strength values received from each of the two beacons from the corresponding point of time to the predetermined distance r2 by the user terminal 10, Can be calculated in real time before entering. Thereafter, when it is determined that the user terminal r2 has reached the predetermined distance r2, the movement direction determination unit 120 calculates an average of the signal intensity values accumulated up to the present time for each of the two beacons , The moving direction can be determined by comparing the two values. If the beacon signals detected from the two beacon units do not have the same identification number, the movement direction determiner 120 determines whether the beacon signals received from the first beacon unit Can be calculated in real time.

The receiving unit 110 may receive the signal strength information corresponding to the movement of the user terminal 10 only from either the first beacon unit 1 or the second beacon unit 2, The moving direction determination unit 120 determines that the signal strength information from both the first beacon unit 1 and the second beacon unit 2 is & The signal strength information received from only one of the first beacon unit 1 and the second beacon unit may be excluded before being received. Specifically, when the beacon signal is received from one beacon unit, the movement direction determination unit 120 may calculate an accumulated value in real time with respect to the signal intensity value of the corresponding beacon signal. At this time, When the signal strength information is simultaneously received from the beacon unit 1 and the second beacon unit 2, the movement direction determination unit 120 calculates the movement direction of the beacon unit 1, And the accumulated value of the signal intensity values detected from the two beacons 1 and 2 can be calculated from the time when the signal intensity information is simultaneously received from the two beacons 1 and 2. [ At this time, the accumulated value can be calculated in real time until the user terminal 2 enters within a predetermined distance r2, and if it is determined that the user terminal has entered (2) within the predetermined distance r2, The direction determination unit 120 may calculate an average value of the accumulated values calculated for each of the two beacons 1 and 2 and determine the direction of movement by comparing the average values.

For example, a pair of first beacons 1 and second beacons 2, which have been given the same identification number in a predetermined space, are provided with a pair of third beacons (not shown) The beacon units 1 and 2 are located at positions close to each other.

When the user terminal 10 receives the beacon signal of the first beacon unit 1 while passing through the predetermined space, the movement direction determination unit 120 determines the direction of the signal detected from the first beacon unit 1, The accumulated value of the value can be calculated in real time. If the receiving unit 110 receives a beacon signal from the third beacon unit, the moving direction determining unit 120 may check whether the first beacon unit and the third beacon unit have the same identification number. Since the first beacon unit and the second beacon unit do not have the same identification number, the movement direction determination unit 120 may accumulate and store the signal intensity values detected from the first beacon unit 1 and the third beacon unit, respectively. When the receiving unit 110 receives the beacon signal from the second beacon unit 2, the moving direction determining unit 120 determines whether the first beacon unit 1 and the third beacon signal are received, Whether or not there is a signal having the same identification number (common service number) as the signal of the beacon unit 2 can be confirmed based on a database (not shown). At this time, since the first beacon unit 1 and the second beacon unit 2 have the same identification number (common service number), the movement direction determination unit 120 determines that the first beacon unit 1 and the second beacon unit 2 have the same identification number (I.e., the accumulated values of the first beacon portion 1 and the third beacon portion) calculated before the point in time when the signal is simultaneously received from the first beacon portion 2 may be initialized (or deleted). The moving direction determination unit 120 determines the moving direction of the beacons 1 and 2 based on the cumulative value of the signal intensity value received from each of the two beacons 1 and 2 from the time when the signals are simultaneously received from the first beacon unit 1 and the second beacon unit 2. [ , But can calculate the cumulative value until the user terminal 2 enters within a predetermined distance r2. Then, the movement direction determination unit 120 can determine the direction of movement of the user through the mutual contrast of the average values of the accumulated values based on whether or not the movement is within the preset distance r2.

The moving direction determination unit 120 determines whether the distance from the user terminal 10 is Far or Far in an interval where the distance from the user terminal 10 is divided into Immediate, Near, Far, and Unknown based on the beacon units 1 and 2 The moving direction of the user can be determined based on the signal intensity information of the first beacon unit 1 and the signal intensity information of the second beacon unit 2. [

In general, the distance between the beacon and the user terminal 10 can be roughly classified into four cases according to the signal intensity value, and the distance from the beacon to the user terminal 10 is about Immediate to about 20 cm, , Far distance up to about 50 ~ 70m, Unknown distance when signal can be detected but distance can not be specified.

In this case, since the distance value is calculated according to the signal intensity between one beacon and the user terminal 10 based on the distances classified into the four cases as described above, the distance range of Far is approximately 3m to 70m And that there is no directionality in the beacon signal, it has been difficult to determine immediately and accurately the direction of movement of a user passing through a specific spot through this conventional technique.

More specifically, as described above, conventionally, since a beacon-based service is installed at a considerable distance (approximately, several tens of meters or more) between the beacons and the beacons, (Or moving tendency) of the user can be detected in a wide area only when the boundary of the four distances is in / out or when the user moves from one beacon detectable area to another beacon detectable area I could only judge it roughly. Thus, if the distance between two beacons is far apart, the user can only roughly determine the moving direction.

Even if two beacons are arranged so as to partially overlap each other, the distance range corresponding to Far is considerably wide, approximately 3 m to 70 m, so that when the user moves in an overlapped area in which two beacons are commonly regarded as the distance range of Far , It is difficult to grasp the moving direction of the user (only two beacons are recognized as Far).

That is, in the prior art, there is a problem in that the determination of the moving direction of the user at a specific spot is considerably unclear and the reliability is low. On the other hand, the user movement direction recognition system 100 according to an embodiment of the present invention can accurately determine the moving direction of the user approaching the near distance within the Far distance range.

The user movement direction recognizing system 100 according to the embodiment of the present invention can recognize the user's moving direction before the user passes the vicinity of the pair of beacons 1 and 2 or enters the predetermined distance r2, By estimating the moving direction based on the cumulative value of the signal intensity values according to the copper wire of the user terminal 10, customized information according to the moving direction when the user passes the vicinity of the pair of beacons 1, As a result, Accordingly, the user movement direction recognition system 100 can determine an instantaneous movement direction of the user so that the user terminal 10 comes close to real time or real time before entering the predetermined distance r2, The set distance r2 may mean a near distance.

At this time, a point (predetermined distance r2) for terminating the accumulation of the signal intensity value and determining the moving direction is fixed to the signal recognition period of the user terminal 10 (for example, 1 second for Apple's IOS, Google's Android can set a desired period of at least 0.5 second) and the tendency of the signal strength value to jump out of the direction of the signal intensity (direction away from the beacon) In order to determine the moving direction of the user before passing the information providing device 2 installed between the beacons 1 and 2 and to provide information suitable for the user, It is best to set it to a position 5m away. However, the predetermined distance r2 is not limited thereto, and may be set differently according to the environment and purpose. Therefore, the user movement direction recognition system 100 according to an embodiment of the present invention derives a beacon signal intensity value sensed (sensed) by the user terminal at a predetermined point through several experiments at a predetermined position (for example, ). If this value is set to a threshold value and the signal detected (sensed) by the user terminal is stronger in actual use, the accumulation of the signal strength value can be terminated and the direction of movement can be determined.

For example, suppose that the signal strength (RSSI) value corresponding to the distance r2, which is the point at which the moving direction is determined, is set to x. In this case, when the user terminal is located within the distance r2, although the signal strength value is measured to be larger than x, a signal strength value at a position within r2 is measured as a value smaller than x . That is, when the user terminal enters within the distance r2, although the signal strength value is measured as a value smaller than x, although the signal strength value of x or more is measured and the accumulation of the signal strength value should be stopped, It is determined that the terminal is located, and an error that the accumulation of the signal strength value is not interrupted may occur.

If the user terminal enters a pair of beacon units in a state where the accumulation of the signal strength values is not interrupted due to such error (error), the beacon unit passed by the user terminal among the pair of beacon units (Reverse accumulation) is performed in a direction in which the signal intensity becomes weaker and weaker with respect to the beacon portion (for example, the second beacon portion) The signal intensity accumulation (forward accumulation) is performed in the direction of stronger, and the reliability in the judgment of the moving direction can be rather lowered.

Accordingly, the predetermined distance r2 (accumulation end point of the signal strength) is determined such that the accumulation of the signal strength between the pair of beacon units is completed in consideration of the above-mentioned tendency of the signal strength measurement error and the general walking speed of the person. Or a predetermined margin value is set in a direction to prevent the accumulation of the signal strength from being terminated in a state where the pair of beacons are passed all over.

The predetermined margin value may be 3 m to 5 m. Generally, a person is known to walk at a speed of about 3 km / h to 5 km / h (average 4 km / h). Specifically, a person walking at a speed of 3 km / h moves about 0.833 meters per second, and a person walking at a speed of 5 km / h can move about 1.389 meters per second. Also, as described above, the signal recognition period in which the user terminal 10 recognizes the beacon signal may be about one second. Under such conditions, in order to overcome the error that the signal strength value is more likely to be measured weakly and to terminate the signal strength accumulation before the user terminal reaches any one of the pair of beacons, the user terminal transmits a beacon signal at least three It is desirable to give the opportunity to recognize and judge the society. That is, the predetermined distance (r2) is 2.499 m (0.833 m / sec [walking speed of the person walking slowly] X 1 sec (general signal recognition period; Ibeacon standard of Apple X 3 times) It is preferable that the walking distance of the walking person is set to about X 1 sec X 3 times], and if the margin is raised by performing the small number re-rounding process, the predetermined distance r 2 is preferably 3 m to 5 m have.

Hereinafter, the present invention generates tailored information according to the movement direction determined by the customized information providing system to be described later, and transmits the generated customized information to the information providing apparatus 20 or the user 20 located between the pair of beacons 1, It is possible to immediately provide the customized information to the terminal 10, thereby providing the customized information immediately to the user passing near the pair of beacons 1, 2. That is, the user can immediately receive the user-customized information according to the moving direction through the information providing device 20 or the user terminal 10 when passing the vicinity of the pair of beacons 1, 2.

Hereinafter, techniques for providing customized information based on the above description will be described.

6 is a schematic block diagram of a customized information providing system 600 according to an embodiment of the present invention.

6, the customized information providing system 600 according to an embodiment of the present invention includes a receiving unit 610, a moving direction determining unit 620, a customized information generating unit 630, and a providing unit 640 .

The customized information providing system 600 may be a server that provides customized information as a system separate from the user terminal 10, as described above.

Here, the description of the user movement direction recognition system 100 may be applied to the customized information providing system 600 as well. Accordingly, the contents described with respect to the user movement direction recognition system 100 can be similarly applied to FIG. 6, even if omitted below.

The customized information providing system 600 can determine the moving direction of the user by using a pair of beacons 1 and 2. Based on the information, customized information corresponding to the user's situation such as the user's location / And the generated user-customized information can be provided in an ambient manner without interfering with the user's existing behavior through the various information providing apparatuses 20 provided in the user terminal 10 or the public place (outside).

The receiving unit 610 and the moving direction determining unit 620 may perform the same functions as the receiving unit 110 and the moving direction determining unit 120 of the user moving direction recognizing system 100. [

The receiving unit 610 may receive a signal intensity corresponding to the movement of the user terminal 10 sensed from the first beacon unit 1 and the second beacon unit 2 spaced apart at a predetermined interval r1, Information can be received. At this time, the receiver 610 can receive the signal strength information detected by the user terminal 10 from the user terminal 10. In addition to the signal strength information, the receiving unit 610 may receive various information required for providing customized information from the user terminal 10.

The movement direction determination unit 620 determines the first coincidence time signal intensity information and the second coincidence time information that are detected during the same time period among the signal intensity information of the first beacon unit 1 and the signal intensity information of the second beacon unit 2, The direction of movement of the user can be determined by comparing the signal strength information with each other. At this time, the moving direction determination unit 620 may directly determine the moving direction of the user based on the information received by the receiving unit 610. [ Alternatively, the movement direction determination unit 620 may simply receive the determination result information (i.e., movement direction information of the user) already determined by the user terminal 10 from the user terminal 10, Can be utilized.

The customized information providing system 600 according to an embodiment of the present invention not only receives judgment result information (i.e., moving direction information of the user) from the user terminal 10 through the receiving unit 610, The identification information of the information providing apparatus 20 located between the two beacons 1 and 2 and the identification information of the USIMs 1 and 2 of the user terminal 10 in order to identify the user of the user terminal 10, User information previously stored in the card or the storage device, and the like.

Data can be transmitted and received between the user terminal 10 and the personalized information providing system 100, that is, the server through the network. Examples of the network include a 3rd Generation Partnership Project (3GPP) network, a Long Term Evolution (LTE) network, a World Interoperability for Microwave Access (WIMAX) network, the Internet, a LAN (Local Area Network) Network, a Wide Area Network (WAN), a Personal Area Network (PAN), a Bluetooth network, a Near Field Communication (NFC) network, a satellite broadcast network, an analog broadcast network, a Digital Multimedia Broadcasting But is not limited thereto.

The customized information providing and generating unit 630 may generate customized information according to the moving direction of the user based on the moving direction information of the user determined by the moving direction determining unit 620. [

The customized information generating unit 630 can generate two pieces of customized information based on the identification information of the information providing apparatus 20, the moving direction information of the user, and the user information. That is, the customized information generating unit 630 can individually generate the publicly-customized information and the private-customized information, and a detailed description will be given below.

The customized information generating unit 630 may generate the publicly-customized information for the purpose of providing the information to the information providing apparatus 20, and the publicly-customized information may include public information that is determined not to be a problem for exposure to the outside It can mean information.

The customized information generating unit 630 can generate the publicly-customized information by simply including the moving direction information of the user and the identification number of the information providing apparatus 20. [ Also, the customized information generating unit 630 may extract the phrase information matching the identification information of the information providing apparatus 20 previously stored in the database (not shown) according to the movement direction information, and generate the phrase information by including the extracted phrase information . In addition, the customized information generation unit 630 can include the user information in the movement direction information to generate the publicly customized information. Examples of publicly-tailored information can be more easily understood with reference to FIGS. 7 and 8. FIG.

FIGS. 7 and 8 are views showing examples of publicly-tailored information provided through a customized information providing system according to an embodiment of the present invention.

7, when the user is moving from right to left with respect to the information providing apparatus 20 disposed between the pair of beacons 1 and 2, the customized information generating unit 630 generates a customized information Publicly-tailored information can be generated based on a phrase such as "go from right to left" The extracted information and the generated public personalized information may be provided to the information providing apparatus 20 through the provision unit 640. Referring to FIG. 8, information such as "go from left to right?" May be displayed as publicly-tailored information on the screen of the information providing apparatus 20, for example. In addition, information such as "(user name), go to a restaurant, today's menu is xxx (price: xxxx won) ", etc., on the screen of the information providing apparatus 20 as publicly- May be displayed.

In addition, the customized information generating unit 630 may generate personalized information for use in providing the information to the user terminal 10, and the personalized information may include personal information of a user determined to be a problem in exposure to the outside May mean included information.

The personalized information generation unit 630 may generate the personalized information by simply including the movement direction information and the user information or may generate the personalized information by generating the phrase information From a database (not shown) and applying the user information to the extracted phrase information.

The personalized information can be personal information (e.g., user's schedule information, user's birthday information, user's personal information, etc.) that can be grasped in the user terminal 10, Location information, user's personal network information, etc.). For example, the customized information generation unit 630 associates the schedule information of the user with the moving direction information as the personalized information, and "moves to the classroom 301. If the user moves 30 meters along the current direction, And the generated personalized information can be provided as a push message or the like on the display of the user terminal 10 through the providing unit 640. [ As another example, the customized information generating unit 630 may associate the user's personal network information with the moving direction information as private-personal information, and may use personal information such as "Job title: Are you moving to Professor Hong Gil Dong's 415? After generating the phrase information, the generated private phrase information may be provided on the user terminal 10 through the provision unit 640.

In addition, the customized information generation unit 630 may synchronize at least one of the time information related to generation and transmission and reception of movement direction information received from the user terminal 10 and the acceleration information of the user terminal 10 with the movement direction information, It is possible to generate customized information corresponding to the situation of the user holding the user terminal 10. [

Illustratively, the receiving unit 610 can receive the receiving time of the moving direction information from the user terminal 10, and then the customized information generating unit 630 generates the publicly- (I.e., customized information corresponding to the situation of the user) can be generated by adding the time-based information of the user. For example, the interworking information generated by the customized information generation unit 630 may include information such as " You are going to a restaurant because of lunch time, " The generated interworking information may be provided to the user terminal 10 or the information providing apparatus 20 by the providing unit 640.

In addition, the customized information generation unit 630 may output the situation determination information of the user determined based on the scalar value of the vibration value irrelevant to the direction measured through the acceleration measurement sensor (not shown) of the user terminal 10, It is possible to generate customized information by interlocking.

Specifically, the receiving unit 610 can receive the acceleration information together with the moving direction information from the user terminal 10. To this end, the user terminal 10 may include an acceleration measurement sensor (not shown) and may provide the acceleration information measured by the acceleration measurement sensor to the customized information providing system 600 via the network. Here, the acceleration measurement sensor may include an acceleration sensor, a gyro sensor, or the like. In addition, the acceleration measurement sensor can precisely measure the acceleration in the moving direction of the user, and can also detect stepwise situation information such as a stop state, a walking state, and a running state based on a preset stepwise critical vibration value Sensor. One example of the acceleration measurement using the acceleration measurement sensor is to accurately measure the acceleration in the moving direction of the user as well as to accurately measure the acceleration in the direction of movement of the user when the user terminal 10 in the pocket of the user- It is possible to measure the vibration measurement value of the acceleration measurement sensor according to the sudden shaking in the user terminal 10 or the shaking of the user terminal 10 in the hand. At this time, due to rapid shaking of the user terminal 10, the vibration measurement value measured through the acceleration measurement sensor can be increased. Accordingly, the customized information generation unit 630 can determine that the user is in a state of urgent movement based on the vibration measurement value through the acceleration measurement sensor, and can generate customized information in consideration of the determined situation.

That is, the customized information generating unit 630 generates the interworking information (i.e., phrase information) in which the acceleration information or the vibration level information is linked with the moving direction information of the user, and the providing unit 640 supplies the generated interworking information to the customized information To the information providing apparatus 20 or the user terminal 10 together with the information. For example, the interlocking information associated with the acceleration information or vibration value information may include phrases such as " Go to the restaurant hastily, and it will arrive within one minute if you run. &Quot;

The providing unit 640 may provide the customized information generated by the customized information generating unit 630 to at least one of the information providing apparatus 20 and the user terminal 10 provided outside. Here, the information providing apparatus 20 may be located between the first beacon unit 1 and the second beacon unit 2 spaced apart at a predetermined interval.

The providing unit 640 provides the publicly-tailored information according to the moving direction to the information providing apparatus 20 through the network, and provides the personalized information according to the moving direction to the user terminal 10. In this case, as described above, the publicly-tailored information and the private-personalized information may be information considering time information, acceleration information, vibration value information, and the like related to generation of movement direction information and transmission / reception, in addition to movement direction information.

FIG. 9 is a diagram illustrating an example of customized information provided through the customized information providing system 600 according to an embodiment of the present invention.

9, assume that a service apparatus including a pair of beacons 1 and 2 and an information providing apparatus 20 located therebetween is arranged in a lobby (hall) of a hotel or the like.

At this time, when the user passes the service device in front of the service device in the direction of the accommodation (specifically, the room) where the user is staying from the outside (outside), the customized information generating part 630, The user terminal 10 or the information providing apparatus 20 may provide the customized information including the location (room number) or the event performed in the hotel according to the characteristics of the information.

Specifically, the room location information of the hostel can be classified as personalized information, and thus, the providing unit 640 provides personalized information such as "your room location is xx" to the user terminal 10 can do. In addition, the event information provided in the hotel can be classified as publicly-tailored information, and thus, the providing unit 640 provides personalized information to the user terminal 10, and at the same time, And "xxx" is the hotel event information for the hotel.

On the other hand, in another example, when the user passes in front of the service device in the direction of the outside (outside) from the host, the customized information generating unit 630 generates a personalized schedule (schedule) Can be provided to the user terminal 10 or the information providing apparatus 20 in accordance with the characteristics of the information.

Specifically, the personal schedule information can be classified into personalized information, and thus the offer 640 can be classified into personalized information such as " Your present schedule is xx, and the recommended tourist information includes xx, Customized information can be provided to the user terminal 10. [ In addition, the neighboring tourist information can be classified as publicly-tailored information, and thus the providing unit 640 provides personalized information to the user terminal 10, and at the same time, xx, etc. "can be provided.

Hereinafter, the operation flow of the present invention will be briefly described based on the details described above.

FIG. 10 is a schematic operation flowchart of a method of recognizing a user movement direction according to an embodiment of the present invention.

10 can be performed by the user movement direction recognition system 100 and the customized information providing system 600 described above. Accordingly, the contents described for the user movement direction recognition system 100 and the customized information provision system 600 can be similarly applied to FIG. 10, even if omitted below.

Referring to FIG. 10, in step S1010, signal intensity information according to movement of the user terminal 10 sensed from the first beacon unit 1 and the second beacon unit 2, which are spaced apart at a predetermined interval, .

At this time, the predetermined interval may be spaced apart from each other in the direction corresponding to the user's movement in the space where the first beacon portion 1 and the second beacon portion 2 are arranged.

In addition, the predetermined interval may be an interval within the error range of the distance between the user terminal 10 and the beacon calculated based on the signal strength of the beacon.

Next, in step S1020, the first coincidence time signal intensity information and the second coincidence time signal intensity detected during the same time interval of the signal intensity information of the first beacon section 1 and the second beacon section 2 The direction of movement of the user can be determined by comparing the information with each other.

At this time, in step S1020, the point in time when the signal intensity information of the first beacon unit 1 and the signal intensity information of the second beacon unit 2 are simultaneously detected can be recognized as the start point of the same time range. If it is determined in step S1020 that the user terminal 10 has reached the predetermined distance r2 from the first beacon unit 1 or the second beacon unit 2 within a predetermined signal intensity, It can be recognized as the end point.

In addition, in step S1020, the first determination value based on the cumulative value of the first coincident signal strength information and the second determination value based on the cumulative value of the second coincidence signal strength information are compared with each other The moving direction can be determined. In this case, the first determination value may be an average value of the accumulated values of the first coincidence signal strength information, and the second determination value may be an average value of the accumulated coincidence information of the second coincidence time information.

In step S1020, as a result of the mutual contrast, in the direction toward the position of the beacon corresponding to the determination value having a small value at the position of the beacon corresponding to the determination value having the larger of the first determination value and the second determination value, It can be judged that the mobile terminal moves.

When at least one of the first coincidence time signal strength information and the second coincidence time signal strength information is not detected at the same time in the same time range, the first coincidence time signal strength information and the second coincidence time signal strength information The detected information among the time signal intensity information can be excluded in the cumulative value calculation.

In addition, the first beacon unit 1 and the second beacon unit 2 may be arranged in a pair corresponding to the moving direction to be determined and may be given the same identification number.
