Method of providing posture measurement and related services

[0001] The present invention relates to a method for providing posture measurement and related services that can be easily used in various places such as at home, and more specifically, to a method for providing posture measurement and related services that can accurately derive a user's posture by wearing a plurality of posture measurement devices on different parts of the user's body and provide useful services related thereto.

[0002] Recently, much research has been conducted to build and improve systems that can accurately determine human posture across various fields, including medical, sports / exercise, and virtual reality / gaming.

[0003] The most widely used posture determination systems to date are the method of acquiring image data using an imaging device such as a camera, recognizing the motion of the subject shown in the image data, and the method of attaching markers to various parts of the subject's body and performing motion capture by optically sensing them.

[0004] However, in the former case, although it is possible to remotely recognize a person's movements using a camera, there are issues with privacy or personal information exposure depending on the specific situation or purpose, and in particular, it is difficult to accurately recognize the target's movements and quantify them.

[0005] In addition, the latter has the advantage of high accuracy of movement as it can accurately imitate the movement of the target, but the equipment for operating it is large and expensive, and the entire process is complex, so it has limitations in that it is limited to use in specific fields such as movies and games.

[0006] Therefore, a method to solve these problems is required.

[0007] The present invention is an invention devised to solve the problems of the above-described prior art, and has the purpose of providing posture measurement and related services that can be applied in various fields by utilizing simple and lightweight equipment and capable of analyzing a user's posture with high accuracy.

[0008] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0009] The posture measurement and related service provision method of the present invention for achieving the above-described purpose is a posture measurement method performed in a state where one or more first posture measurement devices and one or more second posture measurement devices, each including a wireless communication module, are worn on different parts of the user's body, and distance information between the first posture measurement devices and the second posture measurement devices is calculated through a process of transmitting and receiving a reference signal between the respective wireless communication modules provided in the first posture measurement devices and the second posture measurement devices, and a posture derivation unit derives the user's posture information based on the distance information.

[0010] At this time, the first attitude measurement device includes a tag-type first wireless communication module that transmits and receives a first reference signal, and the second attitude measurement device includes an anchor-type first wireless communication module that transmits and receives a first reference signal, and the tag-type first wireless communication module transmits the first reference signal and the anchor-type first wireless communication module receives the first reference signal, the anchor-type first wireless communication module transmits the first reference signal and the tag-type first wireless communication module receives the first reference signal, the anchor-type first wireless communication module calculates distance information between the first attitude measurement device and the second attitude measurement device based on the transmission and reception times of the first reference signal, the anchor-type first wireless communication module calculates distance information between the first attitude measurement device and the second attitude measurement device, the tag-type first wireless communication module and the anchor-type first wireless communication module transmit the distance information to the attitude derivation unit, and the attitude derivation unit It includes step (e) of deriving user's posture information based on distance information.

[0011] At this time, the one or more first posture measurement devices and the one or more second posture measurement devices may be installed in pairs or not in pairs and distributed on the user's body.

[0012] In addition, when the first posture measuring device and the second posture measuring device are paired with each other, the first posture measuring device and the second posture measuring device may be mounted in a symmetrical manner based on a virtual center line that vertically divides the user's body.

[0013] And in the step (c), the anchor-type first wireless communication module provided in each of the one or more second attitude measurement devices can individually calculate distance information with respect to each of the one or more first attitude measurement devices.

[0014] Additionally, the first posture measurement device and the second posture measurement device may further include a second wireless communication module that measures distance information between each other through a second reference signal to which a different wireless communication method is applied from the first reference signal and transmits the measured distance information to the posture derivation unit.

[0015] In such a case, between the above steps (d) and (e), a step (ex) may be further performed in which the detailed information derivation unit selects one of the distance information transmitted from at least one of the tag-type first wireless communication module and the anchor-type first wireless communication module and the distance information transmitted from the second wireless communication module according to a preset priority.

[0016] Meanwhile, the posture derivation unit is linked to a software driving unit that drives training software installed on a user terminal owned by the user, and in this case, the present invention may further include a step (add1) in which the software driving unit displays training motion information to be performed by the user through the training software, a step (add2) in which the posture derivation unit transmits the posture information derived through steps (a) to (e) to the software driving unit, a step (add3) in which the software driving unit determines whether the training motion information and the posture information match, and a step (add4) in which the software driving unit increases a motion count and displays it through the training software when the training motion information and the posture information are determined to match each other through step (add3).

[0017] The present invention's posture measurement and related service provision method for solving the above-described problem has the advantage of being able to accurately derive a user's posture in a simple manner by wearing multiple posture measurement devices with wireless communication modules applied to different parts of the user's body, and also being able to provide various useful related services that can utilize the derived posture.

[0018] In addition, the equipment for implementing the present invention can be constructed at low cost, which is advantageous for popularization and commercialization, and the entire process for deriving the posture is simpler than the existing image method or optical method of deriving the posture, so it has the advantage of minimizing the amount of data.

[0019] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0035] FIG. 1 is a conceptual diagram illustrating the configuration of a system for implementing a method for providing posture measurement and related services according to one embodiment of the present invention.

[0036] As illustrated in FIG. 1, a system for implementing a posture measurement and related service provision method according to the present invention includes a first posture measurement device (100), a second posture measurement device (200), and a posture derivation unit (20).

[0037] The first posture measurement device (100) and the second posture measurement device (200) can be worn on different parts of the user's body for the purpose of measuring the user's posture.

[0038] And for this purpose, the first posture measurement device (100) and the second posture measurement device (200) may each include one or more wireless communication modules (110, 210).

[0039] The wireless communication module (110, 210) transmits and receives a reference signal through wireless communication, and through this process, derives the distance between the first attitude measurement device (100) and the second attitude measurement device (200) to generate distance information.

[0040] Any device capable of wireless communication, such as a wireless communication module (110, 210), can be applied without limitation.

[0041] For example, the wireless communication method of the wireless communication module (110, 210) may be applied to various wireless communication methods such as Wi-Fi, Bluetooth, UWB (Ultra-Wideband), Zigbee, infrared, etc., and may include all devices that can communicate with each other through various wireless communication means.

[0042] And the posture derivation unit (20) derives the user's posture information based on the distance information generated by the wireless communication module (110, 210).

[0043] Below, an embodiment that specifically implements the present invention will be described.

[0044] In one embodiment of the present invention, the first posture measurement device (100) may include a tag-type first wireless communication module (110) that transmits and receives a first reference signal, and the second posture measurement device (200) may include an anchor-type first wireless communication module (210) that transmits and receives a first reference signal.

[0045] And the method for providing posture measurement and related services according to the present embodiment can be performed while at least one first posture measurement device (100) and at least one second posture measurement device (200) are worn on different parts of the user's body.

[0046] At this time, one or more first posture measurement devices (100) and one or more second posture measurement devices (200) may be configured to form a pair with each other according to their purpose, as in the embodiments described below, or may be configured not to form a pair with each other.

[0047] The posture derivation unit (20) is configured to derive the user's posture information through distance information derived by the tag-type first wireless communication module (110) and the anchor-type first wireless communication module (210).

[0048] In the present embodiment, the posture derivation unit (20) is set to be a logical unit implemented by the processor of the user terminal (10) owned by the user, but this is only an example, and the posture derivation unit (20) is not necessarily implemented by the processor of the user terminal (10).

[0049] For example, it goes without saying that the posture derivation unit (20) may be implemented by a separate computing device such as a personal computer, an operation server, etc., in addition to the user terminal (10).

[0050] Meanwhile, in this embodiment, the user terminal (10) may further include a software driving unit (30), which is a logical unit for driving training software installed on the user terminal (10) owned by the user, and this will be described later.

[0051] Regarding the first posture measurement device (100) and the second posture measurement device (200) of the present embodiment, the first posture measurement device (100) and the second posture measurement device (200) form a pair, and two groups of such pairs can be provided and distributed and mounted on the user's body.

[0052] Specifically, in the case of the present embodiment, when the first posture measurement device (100) and the second posture measurement device (200) are arranged in pairs and in two groups, one first posture measurement device (100) is placed on one side of a virtual center line that vertically divides the user's body for each group, and one second posture measurement device (200) is placed on the other side.

[0053] In addition, the first posture measurement equipment (100) in one group and the second posture measurement equipment (200) in another group are arranged in an interlocked manner so that they are adjacent to each other.

[0054] The reason why the first posture measurement equipment (100) and the second posture measurement equipment (200) configured as a pair in this embodiment are arranged symmetrically and staggered like this is a core part of the present invention, and since the first posture measurement equipment is paired with the second posture measurement equipment in the group to which it belongs and also paired with the second posture measurement equipment in another group, as a result, the first posture measurement equipment and the second posture measurement equipment existing in both groups are paired with each other, so that a total of four pieces of distance information can be obtained.

[0055] In this way, the present invention can derive the user's posture information by applying a method of distributing and mounting the first posture measurement device (100) and the second posture measurement device (200) on the body.

[0056] More specifically, when applying the first posture measuring device (100) and the second posture measuring device (200) to the body, considering that the two wrists, two ankles, and two shoulders of the human body, which are the subjects of movement, are configured symmetrically based on the virtual center line that divides the body into new parts, the first posture measuring device (100) and the second posture measuring device (200) are alternately placed on adjacent parts of the body (e.g., the right wrist and right ankle, the right ankle and the left ankle, etc.).

[0057] That is, the present invention can effectively identify the movement of the upper and lower limbs of the body by obtaining distance information through the first posture measurement device (100) and the second posture measurement device (200) having such an arrangement.

[0058] In particular, in this embodiment, the two first posture measurement devices (100) are exemplified as being mounted on the user's right wrist and left ankle, respectively. For convenience of explanation below, the first posture measurement device (100) mounted on the right wrist is referred to as the 1-1 posture measurement device (100-1), and the first posture measurement device (100) mounted on the left ankle is referred to as the 1-2 posture measurement device (100-2).

[0059] In addition, two second posture measurement devices (200) are exemplified as being mounted on the user's left wrist and right ankle, respectively. For convenience of explanation below, the second posture measurement device (200) mounted on the left wrist is referred to as the 2-1 posture measurement device (200-1), and the second posture measurement device (200) mounted on the right ankle is referred to as the 2-2 posture measurement device (200-2).

[0060] In addition, in this embodiment, the tag-type first wireless communication module (110) equipped in the first posture measurement device (100) and the anchor-type first wireless communication module (210) equipped in the second posture measurement device (200) are exemplified as having a UWB wireless communication method.

[0061] Below, we will describe in detail the method for providing posture measurement and related services performed through the above-described system. In the following description, the same drawing symbols for each component as in Figure 1 will be used.

[0062] FIG. 2 is a diagram showing the entire process of a method for providing posture measurement and related services according to one embodiment of the present invention.

[0063] As illustrated in FIG. 2, the method for providing posture measurement and related services according to the present embodiment may include steps (a) to (e).

[0064] Step (a) is a process in which a tag-type first wireless communication module (110) transmits a first reference signal and an anchor-type first wireless communication module (210) receives the first reference signal.

[0065] And step (b) is a process in which the anchor-type first wireless communication module (210) transmits the first reference signal and the tag-type first wireless communication module (110) receives the first reference signal.

[0066] That is, in steps (a) and (b), mutual transmission and reception of the first reference signal between the tag-type first wireless communication module (110) and the anchor-type first wireless communication module (210) is performed.

[0067] At this time, steps (a) and (b) comprehensively encompass the wireless communication process between wireless communication modules (110, 210), and are not necessarily performed sequentially in time series, and may be performed regardless of the order of each other or may be performed simultaneously.

[0068] Additionally, steps (a) and (b) may each be performed n times (n is 0 and a natural number), and steps (a) and (b) are not necessarily performed the same number of times.

[0069] For example, in the present embodiment, since UWB wireless communication is applied, step (a) is performed in which the tag-type first wireless communication module (110) transmits the first reference signal and the anchor-type first wireless communication module (210) receives the first reference signal.

[0070] And after step (b) is performed in which the anchor-type first wireless communication module (210) transmits the first reference signal and the tag-type first wireless communication module (110) receives the first reference signal, step (a) in which the tag-type first wireless communication module (110) transmits the first reference signal and the anchor-type first wireless communication module (210) receives the first reference signal can be performed.

[0071] That is, in this embodiment, a communication process between a tag-type first wireless communication module (110) and an anchor-type first wireless communication module (210) can be performed through the process of step (a) - step (b) - step (a).

[0072] According to this process, in steps (a) and (b) of the present embodiment, both the anchor-type first wireless communication module (210) equipped in the 2-1 posture measurement device (200-1) and the anchor-type first wireless communication module (210) equipped in the 2-2 posture measurement device (200-2) receive the first reference signal transmitted from the tag-type first wireless communication module (110) equipped in the 1-1 posture measurement device (100-1) and the tag-type first wireless communication module (110) equipped in the 1-2 posture measurement device (100-2), and transmission and reception of the first reference signal can also be performed in the opposite direction.

[0073] Next, step (c) is a process in which the anchor-type first wireless communication module (210) calculates distance information between the first attitude measurement device (100) and the second attitude measurement device (200) based on the transmission and reception times of the first reference signal.

[0074] For example, the anchor-type first wireless communication module (210) equipped in the 2-1 posture measurement device (200-1) can calculate the distance to the tag-type first wireless communication module (110) equipped in the 1-1 posture measurement device (100-1) and the 1-2 posture measurement device (100-2) based on the transmission time information included in the first reference signal, the reception time information of the first reference signal, and the mutual exchange transmission speed of the first reference signal.

[0075] That is, through this process, distance information (Hd) between the 1-1 posture measurement equipment (100-1) and the 2-1 posture measurement equipment (200-1), distance information (Rd) between the 1-1 posture measurement equipment (100-1) and the 2-2 posture measurement equipment (200-2), distance information (Ld) between the 1-2 posture measurement equipment (100-2) and the 2-1 posture measurement equipment (200-1), and distance information (Fd) between the 1-2 posture measurement equipment (100-1) and the 2-2 posture measurement equipment (200-2) can all be derived.

[0076] Next, step (d) is a process in which at least one of the tag-type first wireless communication module (110) and the anchor-type first wireless communication module (210) transmits distance information to the attitude derivation unit (20), and step (e) is a process in which the attitude derivation unit (20) derives the user's attitude information based on the distance information received in step (d).

[0077] That is, through the above process, the present invention can quickly and accurately derive the user's detailed information.

[0078] Meanwhile, in some cases, the user's posture estimated in this embodiment may not be able to determine whether the user performed the posture while standing or lying down.

[0079] To this end, at least one of the first posture measurement equipment (100) and the second posture measurement equipment (200) may be additionally equipped with an inertial measurement sensor.

[0080] In this case, the angle sensing value of the inertial measurement sensor can be used to determine whether the user's body is standing vertically on the ground, or lying down or prone, so more accurate results can be derived.

[0081] Meanwhile, as described above, the user terminal (10) may further include a software driving unit (30), which is a logical unit for driving training software installed on the user terminal (10) owned by the user, and the posture derivation unit (20) may be linked with the software driving unit (30) to provide various related services to the user.

[0082] In this embodiment, the software driving unit (30) is exemplified as providing a training service based on the user's posture information derived through the posture derivation unit (20) through training software.

[0083] FIG. 3 is a diagram illustrating a process of providing a training service through training software in connection with a method for providing posture measurement and related services according to one embodiment of the present invention.

[0084] As illustrated in Fig. 3, the process of providing a training service through training software may include steps (add1) to (add4).

[0085] (add1) step is a process in which the software driver (30) displays training movement information that the user must perform through the training software.

[0086] For example, the software driver (30) can induce the user's training movements by displaying various training movement information, such as push-ups, squats, lunges, etc., through the display of the user terminal (10).

[0087] And when the user performs the training movement, the user's detailed information can be derived through steps (a) to (e) described above.

[0088] Next, step (add2) is a process in which the posture derivation unit (20) transmits the posture information derived through steps (a) to (e) to the software driving unit (30), and step (add3) is a process in which the software driving unit (30) determines whether the training motion information provided in step (add1) matches the posture information transmitted in step (add2).

[0089] That is, the software driving unit (30) determines whether the posture information transmitted from the posture derivation unit (20) matches the training movement that the user must perform.

[0090] And the (add4) step is a process in which, if the software driver (300) determines that the training motion information and the detailed information match each other through the (add3) step, the motion count is increased and displayed through the training software.

[0091] That is, when the user performs the correct training movement, the software driver (30) increases the count for the movement by 1 and displays it through the training software so that the user can determine the current number of training movements.

[0092] FIG. 4 is a photograph exemplifying various training postures that can be analyzed through a posture measurement and related service provision method according to one embodiment of the present invention.

[0093] As illustrated in FIG. 4, the present invention can identify various training postures such as push-ups, squats, lunges, etc., and thus can provide various training services to users.

[0094] At this time, in order to derive accurate posture information by distinguishing distance information that may be similar to each other, such as the 'kneeling push-up' posture in which the subject lies face down close to the ground and the 'squat' posture in which the subject stands vertically on the ground, the first posture measurement device (100) and the second posture measurement device (200) may additionally be equipped with a barometer.

[0095] Hereinafter, other embodiments of the present invention will be described. In each embodiment described below, redundant descriptions of components provided in the same manner as in the aforementioned embodiment will be omitted.

[0096] FIG. 5 is a conceptual diagram illustrating the configuration of a system for implementing a method for providing posture measurement and related services according to another embodiment of the present invention.

[0097] In another embodiment of the present invention illustrated in FIG. 5, as in the above-described embodiment, the user is equipped with two first posture measurement devices (100) and two second posture measurement devices (200), and further, the first posture measurement device (100) is equipped with a tag-type first wireless communication module (110), and the second posture measurement device (200) is equipped with an anchor-type first wireless communication module (210).

[0098] And in the case of this embodiment, the first posture measurement device (100) and the second posture measurement device (200) have the characteristic of further including a second wireless communication module (120, 220) that measures distance information between each other through a second reference signal to which a different wireless communication method is applied and transmits the measured distance information to the posture derivation unit (20).

[0099] That is, in this embodiment, the first posture measurement device (100) and the second posture measurement device (200) have the characteristic of additionally including a second wireless communication module (120, 220) that derives distance information through a different wireless communication method than the tag-type first wireless communication module (110) and the anchor-type first wireless communication module (210) described above.

[0100] The reason for applying two wireless communication modules (110, 120, 210, 220) simultaneously to one posture measurement device (100, 200) is to enable the two wireless communication modules (110, 120, 210, 220) to mutually complement each other's distance information.

[0101] In this embodiment, the second wireless communication module (120, 220) is exemplified as performing wireless communication via infrared rays, but the wireless communication method of the second wireless communication module (120, 220) is not limited thereto.

[0102] FIG. 6 is a diagram showing the entire process of a method for providing posture measurement and related services according to another embodiment of the present invention.

[0103] As illustrated in FIG. 6, the method for providing posture measurement and related services according to the present embodiment may include steps (a) to (e), and may further include step (ex) performed between steps (d) and (e).

[0104] Here, steps (a) to (c) are performed in the same manner as in the above-described embodiment, and thus a detailed description thereof will be omitted.

[0105] And separately from steps (a) to (c), the second wireless communication module (120, 220) calculates distance information through the second reference signal.

[0106] In the subsequent step (d), at least one of the tag-type first wireless communication module (110) and the anchor-type first wireless communication module (210) and the second wireless communication module (120, 220) transmits distance information to the positioning unit (20).

[0107] That is, in this process, the detail derivation unit (20) receives distance information derived in two ways.

[0108] And (ex) step is a process in which the detail derivation unit (20) selects one of the distance information transmitted from at least one of the tag-type first wireless communication module (110) and the anchor-type first wireless communication module (210) and the distance information transmitted from the second wireless communication module (120, 220) according to a preset priority.

[0109] The reason for doing this is that the distance information derived in each of the two ways may differ from each other due to errors, noises, etc. of each wireless communication module (110, 120, 210, 220), and in such cases, the posture derivation unit (20) uses only one distance information with a higher priority according to a preset standard.

[0110] Next, in step (e), the posture derivation unit (20) derives the user's posture information based on the distance information selected in step (ex).

[0111] In this way, the present invention can further improve the accuracy by simultaneously applying wireless communication modules (110, 120, 210, 220) using different wireless communication methods to the first posture measurement device (100) and the second posture measurement device (200).

[0112] Meanwhile, in each of the embodiments described above, two first posture measurement devices (100) and two second posture measurement devices (200) are used as examples, but the number of first posture measurement devices (100) and second posture measurement devices (200) can be set in various ways.

[0113] FIG. 7 and FIG. 8 are drawings showing examples of various methods of mounting multiple posture measurement devices on a user's body in a posture measurement and related service provision method according to the present invention.

[0114] In the case of (A) of Fig. 7, the first posture measurement device (100) is mounted on the right wrist, and the second posture measurement device (200) is mounted on the left wrist, forming a pair.

[0115] In the case of (B) of Fig. 7, the first posture measurement device (100) is provided on the abdomen, and two second posture measurement devices (200) are provided, each mounted on the right ankle and left ankle.

[0116] In the case of (A) of Fig. 8, the first posture measurement device (100) is mounted on the abdomen, and the second posture measurement device (200) is mounted on the neck, right wrist, left wrist, right ankle, and left ankle, a total of five pieces.

[0117] In the case of (B) of FIG. 8, a total of three first posture measurement devices (100) and a total of three second posture measurement devices (200) are provided in pairs that correspond to each other and are alternately installed. Specifically, a total of three first posture measurement devices (100) are installed on the right wrist, left ankle, and left shoulder, respectively, and a total of three second posture measurement devices (200) are installed on the left wrist, right ankle, and right shoulder, respectively.
