Description

Swing analysis method based on grip pressure sensing and device for the same

[0001] The present invention relates to a swing analysis method and an apparatus for the same, and more specifically, to a swing analysis method based on grip pressure sensing and an apparatus for the same.

[0002] The golf swing is a complex and sophisticated motion, and various tracking methods have been developed for accurate analysis and improvement. In particular, recent technological advancements have significantly improved the accuracy and accessibility of golf swing analysis.

[0003] Accordingly, modern golf swing analysis methods can be broadly categorized into three types. First is the method using 3D motion capture systems. This method obtains precise 3D motion data by filming markers attached to the golfer's body and club using multiple high-speed cameras. Second is the method using an Inertial Measurement Unit (IMU). Small sensors attached to the golfer's wrist or club collect data such as acceleration, angular velocity, and direction in real time. Third is the video analysis method utilizing artificial intelligence and computer vision technologies. This method is highly accessible as it can automatically analyze a swing using only video captured with a standard smartphone.

[0004] Accordingly, the present invention aims to provide a system capable of measuring grip pressure in real time using a golf club grip and analyzing pressure changes at key points of a swing based on the measured data.

[0005] The present invention is intended to provide a swing analysis method based on grip pressure sensing and an apparatus for the same.

[0006] The technical problems to be solved by the present invention are not limited to the above technical problems, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0007] As an embodiment of the present invention for solving the above-mentioned problem, a swing analysis method for a swing measuring device based on grip pressure sensing comprises: a step of measuring pressure sensing data through a pressure sensing sensor according to a first time interval based on the grip pressure of a user; a step of measuring swing data through a swing sensing sensor module according to a second time interval based on the movement of the user; a step of generating valid swing data among the swing data based on the timing at which the first time interval and the second time interval match; and a step of generating swing analysis data based on grip pressure for each swing stage according to the valid swing data.

[0008] Furthermore, the pressure sensing sensor and the swing sensing sensor module may be characterized by being positioned spaced apart from each other in one area of ​​the golf club.

[0009] Furthermore, the step of measuring the pressure sensing data according to a first time interval may be characterized by including: a step of applying an electrical signal according to the first time interval to a first axis; and a step of measuring a pressure sensing signal corresponding to the electrical signal transmitted through a second axis that is mutually orthogonal to the first axis; furthermore, the pressure sensing signal may be characterized by being generated by grip pressure at a point where the first axis and the second axis are mutually orthogonal.

[0010] Furthermore, the second time interval may be characterized as being set to be shorter than the first time interval. Furthermore, the step of extracting the valid swing data may be characterized by including: a step of setting a valid swing section on the swing data in which the user's movement matches a preset swing trajectory; and a step of selecting specific swing data that matches the measurement time of the pressure sensing data measured according to the first interval from among the swing data measured according to the second interval on the valid swing section, and extracting it as valid swing data. Furthermore, the step of setting the valid swing section may be characterized by setting the start time of the valid swing section in reverse chronological order at the point when the event according to the preset swing trajectory is completed.

[0011] Furthermore, the method may further include a step in which the pressure sensing sensor and the swing sensing sensor module are activated by a pre-set gesture for the user.

[0012] According to an embodiment of the present invention, a swing analysis method based on grip pressure sensing and an apparatus for the same can be efficiently provided.

[0013] The effects obtainable from the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description below.

[0021] Meanwhile, in the attached drawings, identical components are represented by the same reference numeral.

[0022] In addition, some components in the attached drawings may be exaggerated, omitted, or schematically depicted. This is intended to clearly explain the essence of the invention by omitting unnecessary descriptions unrelated to the essence of the invention.

[0023]

[0024] FIG. 1 is a reference diagram for explaining a swing practice device according to the present invention.

[0025] A swing practice device (1000) according to one embodiment of the present invention can collect and process swing data related to the swing of a user golfer and pressure data related to the pressure with which the golfer grips the golf club. In addition, the swing practice device (1000) can transmit the processed data to an external device. The external device can analyze the transmitted data to correct the golfer's swing trajectory and derive a method to correct the golfer's gripping method of the golf club.

[0026] The swing practice device (1000) described above may include a shaft (10), a head part (20), and a grip part (30).

[0027] The shaft (10) may have a shape that extends in one direction with a predetermined diameter. A head portion (20) may be connected to one side of the shaft (10), and a grip portion (30) may be connected to the other side.

[0028] The shaft (10) may have a shape such as a tube or pipe. Additionally, the shaft (10) may have a shape in which the diameter in the direction of the head portion (20) is smaller than the diameter in the direction of the grip portion (30). Additionally, the shaft (10) may have a shape in which the diameter in the direction of the head portion (20) and the diameter in the direction of the grip portion (30) are the same.

[0029] The head portion (20) is connected to one side of the shaft (10) and can strike the golf ball through the golfer's swing. The head portion (20) may have a shape that allows the golfer to swing and strike the golf ball accurately.

[0030] The grip portion (30) is provided on the other side of the shaft (10) and allows the golfer to grip the swing practice device. The grip portion (30) can be formed from various materials that can improve the golfer's grip. For example, the grip portion (30) can be formed from natural rubber.

[0031]

[0032] FIG. 2 is a reference diagram for explaining a swing measurement module according to the present invention. As shown in FIG. 2, in one embodiment of the present invention, a swing measurement module composed of a swing detection sensor module (100), a capsule structure (200), and a pressure detection sensor module (300) may be provided in an area adjacent to the grip portion (30) of the shaft (10). That is, the swing practice device (1000) may further include a swing measurement module comprising a swing detection sensor module (100), a capsule structure (200), and a pressure detection sensor module (300).

[0033] The swing detection sensor module (100) can be placed inside the shaft (10). In particular, the swing detection sensor module (100) can be mounted in the internal space of the capsule structure (200) and placed within the shaft (10) in an area that overlaps with the grip portion (30) together with the capsule structure (200).

[0034] The swing detection sensor module (100) can process various data for golf practice. For example, the swing detection sensor module (100) can process swing data related to the golfer's swing collected from the pressure detection sensor module (300) and pressure data related to the pressure of the golfer gripping the grip, and generate training data based on the processing results.

[0035] The swing detection sensor module (100) can transmit generated training data to an external device (not shown). To this end, the swing detection sensor module (100) may include a communication unit (110) for transmitting data to an external device. That is, the swing detection sensor module (100) can be connected to an external device via a wireless network. Here, the wireless network may refer to a connection structure capable of exchanging information between each node, such as the swing detection sensor module (100) and the external device. Examples of such networks may include, but are not limited to, RF, 3GPP (3rd Generation Partnership Project) networks, LTE (Long Term Evolution) networks, 5GPP (5th Generation Partnership Project) networks, WIMAX (World Interoperability for Microwave Access) networks, the Internet, LAN (Local Area Network), Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area Network), Bluetooth networks, NFC networks, satellite broadcasting networks, analog broadcasting networks, DMB (Digital Multimedia Broadcasting) networks, etc.

[0036] In addition, in one embodiment of the present invention, the swing detection sensor module (100) is described as being connected to an external device via a wireless network, but is not limited thereto. For example, the swing detection sensor module (100) may be connected to an external device via a wired network. In particular, the swing detection sensor module (100) may be connected to an external device via a data connection device such as a wired cable.

[0037] The swing detection sensor module (100) may also store training data. To this end, the swing detection sensor module (100) may include a memory capable of storing data. In addition to training data, the memory may also store swing data and pressure data.

[0038] Meanwhile, in one embodiment of the present invention, the swing detection sensor module (100) is described as an example of transmitting training data generated by processing swing data and pressure data to an external device, but is not limited thereto. The swing detection sensor module (100) may also transmit the swing data and pressure data to an external device through the communication unit (110) without processing them. In this case, the external device may process the swing data and pressure data and generate training data based on the processing result.

[0039] The capsule structure (200) can be placed inside the shaft (10). In particular, the capsule structure (200) can be placed within the shaft (10) in an area that overlaps with the grip portion (30).

[0040] The capsule structure (200) may have an internal space capable of housing the aforementioned swing detection sensor module (100). As the swing detection sensor module (100) is mounted in the internal space of the capsule structure (200), the swing detection sensor module (100) may be positioned within the shaft (10) in an area overlapping with the grip portion (30). Additionally, as the swing detection sensor module (100) is mounted in the internal space of the capsule structure (200), positional change of the swing detection sensor module (100) due to the golfer's swing may be prevented.

[0041] The capsule structure (200) may have a shape that extends in one direction, for example, in the extension direction of the shaft (10). For example, the capsule structure (200) may have a shape such as a rotating body that extends in one direction.

[0042] In order for the capsule structure (200) to accommodate the swing detection sensor module (100) in its internal space, the capsule structure (200) may be formed to be longer than the length of the swing detection sensor module (100). However, in order to prevent an increase in weight due to the capsule structure (200) and to ensure that the capsule structure (200) is positioned overlapping with the grip portion (30), the capsule structure (200) may be formed to be shorter than the length of the grip portion (30).

[0043]

[0044] The pressure sensing sensor module (300) can collect data related to at least one of the golfer's swing and the gripping pressure of the grip portion (30). For example, the pressure sensing sensor module (300) can collect at least one of swing data related to the golfer's swing and pressure data related to the gripping pressure of the golfer's grip portion (30).

[0045] The pressure sensing sensor module (300) can generate pressure data by converting the pressure applied by the golfer to the grip portion (30) into numerical values ​​for each point and transmit this to the swing sensing sensor module (100).

[0046] The pressure sensing sensor module (300) may be positioned overlapping the grip portion (30). For example, the pressure sensing sensor module (300) may be positioned between the inner circumference of the grip portion (30) and the outer circumference of the shaft (10).

[0047]

[0048] FIGS. 3 and FIGS. 4 are reference diagrams for explaining the configuration of a pressure sensing sensor module according to the present invention.

[0049] The pressure sensing sensor module (300) may include a conductive layer (301), a circuit layer (303), and a separation layer (305). The conductive layer (301), the circuit layer (303), and the separation layer (305) of the pressure sensing sensor module (300) may be disposed between the shaft (10) and the grip portion (30) and may be provided in a stacked form.

[0050] A conductive layer (301) is placed between the shaft (10) and the grip portion (30) and has pressure sensitivity so that the pressure sensing sensor module (300) can detect pressure generated on the grip portion (30).

[0051] The conductive layer (301) may be made of a material that has a change in resistance according to pressure and has resilience. For example, the conductive layer (301) may be made of a pressure-sensitive nonwoven fabric. For example, it may have a sheet resistance of 200 Ω / sq. When pressure is applied to the conductive layer (301), the resistance of the conductive layer (301) may be lowered.

[0052] A conductive layer (301) may be provided between the circuit layer (303) and the grip portion (30). The resistance of the area where pressure is applied in this conductive layer (301) may be lowered. Accordingly, the conductive layer (301) with lowered resistance may conduct only specific locations of the circuit layer (303), thereby allowing the pressure sensing signal at the location where pressure is applied to be transmitted through the circuit layer (303).

[0053] The circuit layer (303) may be positioned facing the conductive layer (301). For example, the circuit layer (303) may be positioned between the shaft (10) and the conductive layer (301).

[0054] The circuit layer (303) can transmit the pressure generated on the conductive layer (301) to the swing detection sensor module (100). That is, the pressure detection sensor module (300) can detect the pressure at each point generated on the grip portion (30), generate pressure data, and transmit the generated pressure data to the swing detection sensor module (100).

[0055] In one embodiment of the present invention, the circuit layer (303) may be provided in the form of a flexible film comprising a plurality of pattern regions (303B) having a plurality of conductive patterns. For example, the circuit layer (303) may be provided in the form of a flexible printed circuit board (FPCB). Here, the plurality of pattern regions (303B) may be spaced apart from each other.

[0056] The challenge pattern included in each pattern area (303B) may include a first challenge pattern (303BA) and a second challenge pattern (303BB).

[0057] When pressure is applied to each pattern area (303B), the first conductive pattern (303BA) and the second conductive pattern (303BB) can come into contact with the conductive layer (301) to form a current path. Therefore, whether pressure is applied to each pattern area (303B) can be determined by whether a signal of current or voltage is transmitted from each pattern area (303B) to the swing detection sensor module (100).

[0058] An output terminal (303A) capable of transmitting pressure data to a swing detection sensor module (100) may be provided on one side of the circuit layer (303). The output terminal (303A) may have a shape extending from one side of the circuit layer (303).

[0059] A separation layer (305) may be placed between the conductive layer (301) and the circuit layer (303). The separation layer (305) may separate or separate the conductive layer (301) and the circuit layer (303) with restorability. Due to such restorability of the separation layer (305) as described above, the pressure sensing sensor module (300) is capable of accurate pressure sensing for local pressure.

[0060] When pressure is applied to the grip portion (30), the conductive layer (301) may be deformed by the pressure, and the separation layer (305) may be compressed. When the conductive layer (301) is deformed by the pressure and the separation layer (305) is compressed, the conductive layer (301) may come into contact with the first conductive pattern (303BA) and the second conductive pattern (303BB) of the pattern area (303B) in the space between the fibers of the separation layer (305). Additionally, the resistance of the area where pressure is applied to the conductive layer (301) may be reduced. Thus, the first conductive pattern (303BA) and the second conductive pattern (303BB) may be electrically connected, allowing current to flow. At this time, the current passing through the first conductive pattern (303BA) and the second conductive pattern (303BB) may be transmitted to the swing detection sensor module (100).

[0061] Here, the current or voltage transmitted from the pressure sensing sensor module (300) to the swing sensing sensor module (100) is changed by the resistance reduced by pressure, and the changed current or voltage can be transmitted to the swing sensing sensor module (100) in the form of pressure data.

[0062] In one embodiment of the present invention, the pressure sensing sensor module (300) may further include a protective layer (307). The protective layer (307) may be provided between the conductive layer (301) and the grip portion (30), and between the circuit layer (303) and the shaft (10). That is, the protective layer (307) is a layer exposed to the outside of the pressure sensing sensor module (300) and can protect the internal conductive layer (301) and the circuit layer (303).

[0063] Meanwhile, although not shown in the drawing, an adhesive layer may be provided between the protective layer (307) attached to the circuit layer (303) and the shaft (10), and between the protective layer (307) attached to the conductive layer (301) and the grip portion (30). The adhesive layer may adhere the pressure sensing sensor module (300) and the shaft (10), and adhere the pressure sensing sensor module (300) and the grip portion (30). Here, the adhesive layer may be made of an adhesive or double-sided tape.

[0064]

[0065] FIG. 5 is a reference diagram regarding a method for analyzing a swing based on grip pressure sensing through a swing measurement module coupled to a swing practice device according to the present invention.

[0066] In the present invention, the pressure sensing sensor module and the swing sensing sensor module on the golf club shaft can be positioned spaced apart from each other in one end region of the shaft as described above.

[0067] For example, the pressure sensing sensor module is positioned overlapping the grip and located between the inner circumference of the grip and the outer circumference of the shaft, configured to collect data by detecting the pressure applied to the grip in real time, and enables accurate pressure measurement by changing the electrical signal according to the pressure change of the grip during a swing.

[0068] The swing detection sensor module can be designed to be located inside the golf club shaft, specifically in the area overlapping with the grip, so that the sensors are protected from the external environment while accurately collecting necessary data.

[0069] Therefore, the pressure sensing sensor module and the swing sensing sensor module are positioned spaced apart from each other by being located inside and outside the shaft in the area overlapping with the golf club grip.

[0070]

[0071] The swing measurement module of the present invention measures pressure sensing data through a pressure sensing sensor module based on the user's grip pressure according to a first time interval (S501). That is, as described above, the swing measurement module positions a pressure sensing sensor module on the outer diameter of a shaft to measure the user's grip pressure, and can measure pressure sensing data based on the user's grip pressure according to a first time interval.

[0072] Accordingly, in the present invention, changes in pressure when a user grips a golf club can be continuously measured through a pressure sensor module mounted on the golf club grip. Furthermore, in the present invention, both piezoelectric pressure sensors and piezoresistive pressure sensors can be utilized as pressure measuring sensors.

[0073] For example, in one embodiment of the present invention, a piezoresistive pressure sensor may be used, and when pressure is applied to the grip, the pressure may be measured using the piezoresistive effect. Furthermore, the user's grip pressure may be detected by using the aforementioned piezoresistive film or layer for piezoresistive pressure sensing.

[0074] The swing measurement module measures swing data at a second time interval through the swing detection sensor module according to the user's movement (S503). In the present invention, the movement data of the club is continuously measured using at least one sensor located inside the golf club shaft to correspond to a pressure detection sensor module located on the outer diameter of the golf club shaft.

[0075] The swing detection sensor module according to the present invention may be composed of at least one sensor combined with an acceleration sensor that measures the linear acceleration of a club, a gyroscope sensor that detects rotational speed and direction, a GPS sensor that tracks the position of a club using GPS, and a geomagnetic sensor that determines the absolute direction and position of a golf club.

[0076] Accordingly, the swing detection sensor module measures the linear acceleration of the club shaft's three axes (X, Y, Z) and rotational speed around the three axes according to a preset second time interval, calculates absolute orientations such as east, west, north, and south based on the club's current direction, and can collect movement information of the entire swing including changes in the club's GPS position, which is used to analyze the club's overall trajectory, speed changes, swing plane, etc.

[0077] The swing measurement module generates valid swing data among the swing data based on the timing at which the first time interval and the second time interval are matched (S505). That is, in the present invention, valid swing data can be generated by pre-setting a time range for matching the first time interval and the second time interval. In other words, the first time interval and the second time interval can be set differently from each other, and valid data for swing analysis is extracted by synchronizing two types of data (grip pressure data and swing data) measured at different time intervals.

[0078] Preferably, the preset matching time range is set to a range smaller than the shorter of the first and second time intervals to prevent abnormal data matching.

[0079] For example, if the first time interval is set to be longer than the second time interval, the time points for measuring swing detection data of the second time interval within a preset range can be identified based on the time point for measuring grip pressure data of the first time interval, and through this, the alignment of the matching between pressure sensing data for grip pressure measured according to the first time interval and swing data detected according to the second time interval can be improved.

[0080]

[0081] If there are multiple measurement points of swing data according to a second time interval within a preset range based on the measurement point of grip pressure data according to a first time interval, proximity-based matching can be performed. For example, it can be determined based on the measurement point according to the second time interval that is temporally closest to the measurement point according to the first time interval, i.e., based on the minimum time difference. In other words, by matching pressure sensing data according to the first time interval and swing data according to the second time interval based on proximity, the correlation between pressure sensing data and swing data can be increased.

[0082] In another embodiment of the present invention, valid swing data can be generated by matching the data of a first time interval and a second time interval with an average value. For example, if the second time interval is set to be a relatively shorter interval than the first time interval, the data of the second time interval within a preset matching time range from a specific measurement point of the first time interval can be identified, and the average value of all data points of the second time interval within that range can be calculated.

[0083] That is, for a specific measurement point of grip pressure data (first time interval), the average value of all swing detection data (second time interval) within a set time range is calculated, and valid swing data can be generated by matching the calculated average value of the swing detection data of the second time interval with the data point of the first time interval.

[0084] Through this, by considering all relevant data within a range instead of selecting a single data point at a specific time, the impact of noise or transient fluctuations can be reduced, and problems caused by differences in data density between two time intervals can be mitigated.

[0085] In another embodiment of the present invention, valid swing data may be generated by interpolating data from a first time interval (long interval) based on data from a second time interval (short interval).

[0086] For example, for each data point in a second time interval consisting of relatively small intervals, the nearest data points in the first time interval are identified. Then, values ​​between the first time intervals can be estimated using interpolation techniques such as linear interpolation or spline interpolation. Various forms of interpolation techniques may be applied to the data, and the interpretation should not be limited to the interpolation techniques described above.

[0087] Valid swing data can be extracted by matching the interpolated grip pressure data of the first time interval with the actually measured swing data of the second time interval. Furthermore, to reduce noise in the extracted interpolated data, a moving average or a Kalman filter may be applied.

[0088] Finally, by preserving time information by maintaining the original second time interval timestamp in the valid swing data, it is possible to generate valid swing data that accurately reflects the grip pressure data of the first time interval based on the second time interval, which has a relatively short interval.

[0089]

[0090] The swing measurement module generates swing analysis data based on grip pressure at each swing stage according to the calculated valid swing data (S507).

[0091] In other words, the swing measurement module identifies the user's swing characteristics by analyzing changes in grip pressure at each stage of the swing—such as address, backswing, downswing, impact, and follow-through—based on valid swing data. Through this, more accurate and detailed swing analysis becomes possible by simultaneously analyzing changes in grip pressure and club movement. Furthermore, by selecting and analyzing only valid swing data that is actually recognized as consistent, errors caused by practice swings or incorrect movements can be reduced.

[0092] That is, in the present invention, during the swing analysis process, an effective swing section is first established in which the user's movement matches a pre-set swing trajectory. The effective swing section in the present invention is the subject of golf swing analysis and is established based on major swing events that match the swing trajectory. Major swing events include address, takeaway, top of backswing, start of downswing, impact, follow-through, etc., and through this, the start and end of the effective swing section can be defined.

[0093] Subsequently, within the effective swing section, pressure sensing data and swing detection data can be generated based on the measurement interval, and swing-stage grip pressure-based swing analysis data can be generated. For example, among the swing data measured according to a relatively short second interval on the effective swing section, specific swing data matching the measurement time of the pressure sensing data measured according to a relatively long first interval can be selected and extracted as effective swing data, and then swing-stage analysis data according to a specific trajectory on the effective swing section can be generated.

[0094]

[0095] FIG. 6 is a reference diagram for explaining a structure for analyzing a swing based on grip pressure sensing through a swing measurement module coupled to a swing practice device according to the present invention.

[0096] The pressure sensing sensor module according to the present invention may have a circuit layer having a structure composed of a first axis and a second axis that are mutually orthogonal. For convenience of explanation, the following description assumes that the first axis (303BA) has a plurality of conductors arranged in a vertical direction and the second axis (303BB) has a plurality of conductors arranged in a horizontal direction, and that they are mutually orthogonal.

[0097] Accordingly, an electrical signal is applied (S601) to the first axis (303BA) according to a preset first time interval. At this time, when grip pressure is applied, the resistance value of the pressure resistance element (e.g., a piezoresistive film or layer) changes. Through this change in resistance value, the electrical signal applied to the first axis flows out to the second axis (303BB), and accordingly, a pressure sensing signal (S603) corresponding to the electrical signal applied to the first axis is measured. That is, since the first axis and the second axis are structured to be mutually orthogonal, the pressure sensing signal corresponding to the grip pressure is accurately measured at the intersection point (303BC) of the two axes. In addition, not only the magnitude of the pressure but also the exact location where the pressure is applied can be detected simultaneously. Therefore, even in the case of multiple touches, grip pressure applied simultaneously at multiple points can be detected independently at each intersection point.

[0098]

[0099] FIG. 7 is a reference diagram illustrating a scenario for extracting valid data from pressure sensing data based on a first time interval and swing data based on a second time interval, according to an embodiment of the present invention.

[0100] In Case A of FIG. 7, when pressure sensing data (711) based on a relatively long first time interval and swing data (721) based on a relatively short second time interval are measured, the swing data (721) within a preset range in the pressure sensing data (711) can be set as valid data.

[0101] On the other hand, in Case B, it is assumed that two sets of swing data (723, 725) corresponding to a relatively short second time interval, which match pressure sensing data (713) based on a relatively long first time interval, are measured within a preset range. In Case B, the distance to the point (723, 725) where each swing data is measured is compared (i.e., 7A, 7B) based on the pressure sensing data (713), and the swing data (723) located at a relatively closer distance (7A) can be selected as valid data.

[0102] Alternatively, as in Case C, if two (727, 729) swing data corresponding to a relatively short second time interval that matches pressure sensing data (713) based on a relatively long first time interval are measured within a preset range, the average value of the measurement data at the points (727, 729) where swing data is measured within the preset range based on the pressure sensing data (715) can be calculated and generated as valid swing data.

[0104] Furthermore, the swing measurement module of the present invention may be configured such that the pressure sensing sensor module and the swing sensing sensor module are activated through a gesture preset by the user. That is, to reduce the power consumption of the swing measurement module and prevent unintended movements, the user may perform gestures such as gripping the club in a specific way or performing a specific movement while holding the grip. Accordingly, when the recognized gesture matches a preset pattern, the sensor module is activated to collect golf swing-related data.

[0105] Furthermore, by utilizing machine learning algorithms and artificial intelligence technology, pressure sensing sensors can recognize pressure in specific areas, and accelerometer sensors can detect specific gestures of the club or wrist. This allows for improved recognition accuracy by learning from diverse user gesture data and further enhances the user experience through customized gesture settings for each user.
