Description

Technical Field

[0001] This application relates to the field of billiards cueing posture correction technology, and more specifically, to a billiards cueing posture auxiliary corrector. Background Technology

[0002] Billiards, as a globally popular sport, demands a relatively high level of technical skill from beginners. Many learners, even after entering the field and after a certain period of practice, still commonly encounter basic problems such as incorrect cueing and improper posture.

[0003] In related technologies, correction products can be mainly divided into three categories: the first is the form-limiting cue guide device, which has the disadvantage that it can only restrict the movement path of the cue and cannot effectively correct the user's body posture, thus only treating the symptoms and not the root cause; the second is the mechanical structure arm limiter, which has a certain posture correction effect, but is bulky and inconvenient to carry, and usually can only locally restrict the rear hand movement, limiting the user's natural force; the third is the sensor-based posture recording system, which can collect motion data, but relies on external devices such as mobile phones for feedback, cannot provide real-time prompts, is difficult to help users form muscle memory, and is also mostly limited to the monitoring of the rear hand movement. Summary of the Invention

[0004] In order to solve the technical problems of limited correction range, bulky equipment and delayed feedback in the above-mentioned related technologies, this application proposes a billiards cueing posture auxiliary corrector.

[0005] In view of this, this application proposes a billiards cueing posture assist corrector, including a glove, a wristband, an elbow pad, and glasses; the glove, elbow pad, and glasses are all equipped with positioning sensors and signal transmitters; the wristband is also equipped with a positioning sensor, a signal receiver, a processor, and a linear motor; the signal transmitter is used to send the positioning signals of the glove, elbow pad, and glasses to the signal receiver; the processor is used to determine a reference plane based on the positioning information of the glasses, and to determine the arm plane based on the positioning information of the glove, wristband, and elbow pad; when it is determined that the arm plane does not coincide with the reference plane, the processor controls the linear motor to generate a vibration prompt.

[0006] In some feasible approaches, the positioning sensor is a laser rangefinder or an infrared sensor.

[0007] In some feasible implementations, the reference plane passes through the positioning reference point of the eyeglasses and is perpendicular to the bridge of the eyeglasses and the ground.

[0008] In some feasible implementations, the processor controls the linear motor to vibrate in an intermittent mode when it determines that the arm surface does not coincide with the reference surface.

[0009] In some feasible implementations, the intermittent vibration mode involves vibrating for N seconds, stopping for M seconds, and repeating the process, where N and M are preset positive integers.

[0010] In some feasible implementations, N=5 and M=1.

[0011] In some feasible implementations, the processor is also used to perform calibration at system startup, using the arm face of the user's initial stationary stick release posture as a temporary reference plane, and gradually switching to the reference plane determined by the glasses in subsequent operations.

[0012] In some feasible implementations, the error threshold for the processor to determine if the arm surface does not coincide with the reference surface is adjustable, and the wristband has an adjustment interface for setting or switching different error threshold levels.

[0013] In some possible implementations, the processor is configured to generate corresponding control signals based on the degree of deviation between the arm surface and the reference surface; the control signals are used to drive the linear motor to generate vibrations of different intensities; wherein, the greater the degree of deviation, the stronger the vibration intensity generated by the linear motor driven by the control signals.

[0014] In some feasible implementations, the billiards stroke correction aid also includes an indicator light mounted on the glasses, which the processor controls to issue a visual warning when it determines that the arm surface does not coincide with the reference surface.

[0015] Compared with related technologies, this application has the following technical advantages: The billiards cueing posture correction device provided in this application includes gloves, wristbands, elbow pads, and glasses. By setting positioning sensors and signal transmitters on the gloves, elbow pads, and glasses respectively, the spatial position information of these parts can be accurately acquired, providing an accurate data basis for subsequent posture judgment. The positioning information from the glasses is used to determine the reference plane, and combined with the positioning information from the gloves, wristbands, and elbow pads, the arm plane is determined. This intelligent determination method simulates the spatial relationship that different parts of the body should have during a billiards cueing stroke, providing a scientific basis for judging the correctness of the posture. The processor judges in real time whether the arm plane coincides with the reference plane. When they do not coincide, it controls a linear motor to generate a vibration prompt, thus effectively integrating wearable computing and real-time haptic feedback technology. This solves the shortcomings of related products in terms of correction range, portability, and real-time feedback, providing a comprehensive, lightweight, and efficient new billiards training aid.

[0016] This billiards cueing posture correction device is lightweight and can provide real-time feedback on whether the cueing posture is correct, which helps the cueing person adjust their posture. Furthermore, because it is a subjective adjustment by the user, the correction effect is more profound, which is conducive to the rapid improvement of billiards skills.

[0017] Additional aspects and advantages of this application will become apparent in the following description or may be learned by practice of this application. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0022] The following reference Figures 1 to 5 This application describes a billiards stroke correction aid according to some embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this application proposes a billiards stroke posture assist corrector, including a glove 100, a wristband 200, an elbow pad 300, and glasses 400; the glove 100, elbow pad 300, and glasses 400 are respectively equipped with positioning sensors and signal transmitters; the wristband 200 is also equipped with a positioning sensor, and the wristband 200 is also equipped with a signal receiver, a processor, and a linear motor; the signal transmitter is used to send the positioning signals of the glove 100, elbow pad 300, and glasses 400 to the signal receiver; the processor is used to determine a reference plane based on the positioning information of the glasses 400, and to determine the arm plane based on the positioning information of the glove 100, wristband 200, and elbow pad 300, and when it is determined that the arm plane does not coincide with the reference plane, it controls the linear motor to generate a vibration prompt.

[0024] The billiards cueing posture correction device provided in this application includes a glove 100, a wristband 200, an elbow pad 300, and glasses 400. By setting positioning sensors and signal transmitters on the glove 100, elbow pad 300, and glasses 400 respectively, the spatial position information of these parts can be accurately obtained, providing an accurate data basis for subsequent posture judgment.

[0025] By using the positioning information of glasses 400 to determine the reference plane, and combining the positioning information of gloves 100, wristbands 200 and elbow pads 300 to determine the arm plane, this intelligent determination method simulates the spatial relationship that the various parts of the body should have when the billiard ball is struck, providing a scientific basis for judging the correctness of posture.

[0026] The processor continuously monitors whether the arm's face aligns with the reference plane. If they do not align, it controls the linear motor to vibrate as a warning. This real-time feedback mechanism promptly alerts the user to adjust their cueing posture, helping them quickly develop correct muscle memory and improving the accuracy and stability of their billiards cueing technique.

[0027] Compared to traditional methods that rely on coach observation or self-feeling to correct posture, this billiards cueing posture correction aid provides objective and accurate posture judgment standards and offers real-time feedback, shortening the time learners take to master the correct cueing posture and improving learning efficiency. The vibration feedback is gentle and intuitive, causing no interference or harm to the user, while allowing the user to easily perceive whether their posture is correct while focusing on the game of billiards, enhancing the overall user experience.

[0028] The billiards stroke posture correction device provided in this application effectively integrates wearable computing and real-time haptic feedback technology, successfully solving the shortcomings of existing products in terms of correction range, portability and real-time feedback, and providing a comprehensive, lightweight and efficient new billiards training aid.

[0029] In some embodiments provided in this application, the positioning sensor is a laser rangefinder or an infrared sensor.

[0030] In this embodiment, the laser rangefinder sensor has high accuracy and fast measurement speed, and can quickly and accurately acquire distance information between the glove 100, elbow pad 300, wristband 200 and glasses 400 and surrounding objects or specific reference points, thereby providing accurate data for determining the position of each part, making the determination of the reference plane and arm plane more accurate, and improving the reliability of posture judgment.

[0031] Infrared sensors are relatively low in cost and power consumption, and have strong adaptability to ambient light. They can work stably under different lighting conditions, ensuring the continuity and stability of positioning. They can effectively detect changes in the position of each component and transmit signals in a timely manner, ensuring that the processor can determine the relationship between the arm surface and the reference surface in real time and quickly control the linear motor to vibrate and alert when the posture is incorrect.

[0032] In some embodiments provided in this application, the reference plane passes through the positioning reference point of the eyeglasses 400 and is perpendicular to the crossbeam of the eyeglasses 400 and the ground.

[0033] In this embodiment, the standard billiards posture is transformed into a stable and uniform spatial geometric plane, providing an objective and quantifiable benchmark for posture correction. This effectively overcomes the errors and inconsistencies caused by traditional reliance on subjective feelings or coaching experience. Moreover, this benchmark cleverly combines head vision (glasses 400) with spatial orientation (perpendicular to the ground). Its orientation is strictly perpendicular to the ground and perpendicular to the beam of glasses 400, ensuring the absolute stability of this plane in space. This effectively filters out interference caused by slight head movements of the user, making the benchmark reference more reliable.

[0034] This plane precisely corresponds in space to the ideal cueing path direction in billiards, that is, it is located in the plane that is perpendicular to the ground and where the aiming line of sight is located. This makes the correction guidance highly consistent with the principles of kinematics, thereby guiding users to form a standard cueing action that is both scientific and ergonomic, significantly improving the scientific nature and effectiveness of training.

[0035] In some embodiments provided in this application, when the processor determines that the arm surface does not coincide with the reference surface, it controls the linear motor to vibrate in an intermittent mode.

[0036] In this embodiment, intermittent vibration, compared to continuous vibration, effectively avoids numbness and discomfort caused by prolonged vibration, improving user comfort and allowing users to practice with the aid of the corrective device for longer periods. Simultaneously, this regular intermittent vibration creates a unique cue rhythm, more clearly attracting the user's attention and enhancing the cuing effect, enabling the user to quickly perceive any deviation in posture. Furthermore, the intermittent mode can adjust the vibration interval and frequency according to the degree of posture deviation; a larger deviation results in a shorter interval and higher frequency, while a smaller deviation results in the opposite, providing the user with more precise posture feedback. This helps the user finely adjust their cueing posture, gradually forming correct muscle memory and improving the accuracy and stability of their billiards stroke.

[0037] In some embodiments provided in this application, the intermittent vibration mode is to vibrate for N seconds, stop for M seconds, and repeat, where N and M are preset positive integers.

[0038] In this embodiment, the intermittent vibration mode achieves both optimized prompting and improved user experience through a cyclical design of "vibrating for N seconds and then stopping for M seconds." First, intermittent tactile stimulation is more likely to alert the user than continuous vibration, preventing them from ignoring the prompts due to tactile adaptation and ensuring that error messages are effectively perceived. Second, while providing continuous reminders, the intermittent periods reduce device power consumption and user discomfort, preventing hand numbness or irritability caused by prolonged vibration. Furthermore, the static periods in the cycle provide users with a real-time adjustment window, allowing them to correct their posture based on feedback before the next vibration, conforming to the "prompt-response-verification" learning pattern. Finally, the presettable parameters N and M allow the prompting rhythm to be flexibly customized according to different users' sensitivity or training stages, enhancing the device's adaptability and practicality.

[0039] In some embodiments provided in this application, N=5 and M=1.

[0040] In this embodiment, the specific parameters of the intermittent vibration mode are set to N=5 and M=1, i.e., a cycle of "vibrate for 5 seconds, stop for 1 second". This parameter combination has been specially optimized. The continuous vibration for 5 seconds ensures that the prompt signal has sufficient time to be clearly perceived by the user, avoiding the possibility of ignoring it due to insufficient vibration. The brief 1-second pause that follows constitutes a crucial information processing and movement adjustment window. During this interval, the user can immediately try to correct their posture based on the feedback and verify the adjustment effect in the next round of vibration. This rhythm is ergonomic, providing continuous and unmistakable reminders while effectively preventing tactile fatigue or discomfort caused by prolonged vibration. Thus, while ensuring the effectiveness of the prompts, it significantly improves the comfort and acceptability of the user experience, optimizing the training experience.

[0041] In some embodiments provided in this application, the processor is also used to perform calibration when the system starts up, using the arm surface of the user in the initial static stick release posture as a temporary reference surface, and gradually switching to the reference surface determined by the glasses 400 in subsequent operations.

[0042] In this embodiment, the arm face of the user in the initial static stick-out posture is used as a temporary reference surface when starting up. This fully considers individual differences and allows the auxiliary corrector to quickly adapt to the natural posture of different users. It avoids frequent false alarms in the early stage due to the large difference between the standard reference surface and personal habits, thus improving the user-friendliness and acceptability.

[0043] The system then gradually switches to the reference plane determined by the glasses (400°), a process that is smooth and natural. With use, it guides users towards a more scientific and standard cueing posture, facilitating the transition from personal habit to a standard posture. This gradual adjustment reduces discomfort and resistance caused by drastic posture changes, making it easier to master the correct cueing posture, improving training effectiveness, and allowing the corrective device to better serve the posture correction needs of different platform golf enthusiasts.

[0044] In some embodiments provided in this application, the error threshold for the processor to determine that the arm surface does not coincide with the reference surface is adjustable, and the wristband 200 is provided with an adjustment interface for setting or switching different error threshold levels.

[0045] In this embodiment, the design is highly adaptable to billiards enthusiasts of different skill levels. Beginners, whose movements are not standardized and lack stability, can have their error threshold set to a higher level, reducing the frequency of prompts and avoiding anxiety caused by frequent vibrations. This allows them to practice more relaxedly and gradually become familiar with the correct posture framework. Professional players, on the other hand, require extremely high precision in their posture and can adjust the error threshold to a lower level to obtain more rigorous and accurate posture feedback, helping them further improve their skills.

[0046] Furthermore, as users practice and improve their posture, they can switch error threshold levels at any time through the adjustment interface to dynamically adjust the training intensity. This personalized and flexible adjustment method allows the assistive corrector to accompany users from beginner to expert, meeting the needs of different stages, effectively improving training results, and helping users master the standard billiards cueing posture faster and better.

[0047] In some embodiments provided in this application, the processor is configured to generate a corresponding control signal based on the degree of deviation between the arm surface and the reference surface; the control signal is used to drive the linear motor to generate vibrations of different intensities; wherein, the greater the degree of deviation, the stronger the vibration intensity generated by the linear motor driven by the control signal.

[0048] In this embodiment, when the deviation is small, a weak vibration is generated to gently remind the user of minor postural errors, avoiding excessive interference with the continuity of their movements. Conversely, when the deviation is large, a strong vibration quickly and intensely attracts the user's attention, clearly informing them that the postural problem is serious and requires immediate and significant adjustment. Vibrations of varying intensities provide the user with a clear "deviation level scale." By experiencing changes in vibration intensity, the user can more intuitively understand the postural deviation, gradually establishing a connection between posture and vibration feedback. This allows for more targeted adjustments to the movement, accelerating the formation of the correct cueing posture and improving training efficiency. Simultaneously, this intelligent feedback mechanism enhances the practicality and effectiveness of the auxiliary corrector, better meeting the user's postural correction needs in different scenarios.

[0049] In some embodiments provided in this application, the billiard cueing posture assist corrector further includes: an indicator light disposed on the glasses 400, wherein the processor controls the indicator light to issue a visual warning when it determines that the arm surface does not coincide with the reference surface.

[0050] In this embodiment, by setting indicator lights on the glasses 400, the original vibration prompting modes are enriched, forming a multi-dimensional prompting system that combines visual and tactile feedback. When the processor determines that the arm surface does not coincide with the reference surface, the indicator light emits a visual warning, which, in conjunction with the vibration prompting of the linear motor, can more comprehensively and effectively attract the user's attention, avoiding the failure to correct posture errors in time due to the neglect of a single prompting method.

[0051] In terms of environmental adaptability, the visual cues are unaffected by ambient noise, allowing users to clearly receive posture deviation signals even in noisy billiard rooms. Furthermore, indicator lights of different colors or flashing frequencies can further differentiate the degree of deviation, providing users with more nuanced feedback. This not only helps users adjust their cueing posture more accurately but also improves training efficiency, enabling users to master the correct movements more quickly and enhancing the experience and effectiveness of using the assistive corrector.

[0052] In practical applications, the processor is also configured to record the duration and frequency of vibrations triggered by the linear motor each time, and generate training reports on user posture stability based on historical data. By recording the trigger data of the linear motor and generating training reports, the functionality has been expanded from real-time correction to long-term analysis. This helps users clearly perceive training effectiveness and progress trends. Through statistical analysis of vibration frequency and duration, the report can objectively reveal the severity and changing patterns of posture problems, providing users with precise directions for improvement. This overcomes the limitations of traditional correction devices that can only provide instantaneous prompts, realizing the digitization, visualization, and scientification of the training process, and significantly improving the system's guidance and practicality.

[0053] Both the wristband 200 and the glasses 400 are equipped with clock modules for synchronizing timestamps. Based on the timestamp information, the processor analyzes the positional relationship between the arm's face and the reference plane, linking it to the user's cueing and striking motion. By introducing a timestamp synchronization mechanism, precise temporal correlation between posture monitoring and striking motion is achieved, accurately pinpointing the specific moment when posture deviations occur (such as during aiming, swinging, or striking), thus refining the general "posture error" into specific problems at different stages of the action. This time-based diagnostic capability makes feedback more targeted, helping users understand the root cause of errors and effectively improving the accuracy and efficiency of corrective training.

[0054] The gloves 100, elbow pads 300, wristbands 200, and glasses 400 all have interfaces on their housings for physical connection. When not in use, they can be magnetically or snapped together to form a single unit. This solves the core pain point of multi-component wearable devices being easily scattered and lost. Through magnetic or snap-fit ​​connections, they can be quickly integrated into a compact whole when not in use, greatly simplifying the carrying and storage process. This not only reduces the risk of component loss but also extends the lifespan of the devices.

[0055] like Figures 1 to 5 As shown, in a specific embodiment, taking a right-handed cue grip as an example, the billiards cueing posture assist corrector provided in this application includes a left-hand glove, a right-hand wristband, an elbow pad 300, and glasses 400. The glove 100, elbow pad 300, and glasses 400 are all equipped with positioning sensors and signal transmitters; the wristband 200 is equipped with a positioning sensor, a signal receiver, a processor, and a linear motor.

[0056] The glove 100, elbow pad 300, and glasses 400 send positioning signals to the receiver of the wristband 200, where they are processed in real time by the processor. The processing flow is as follows: Using the positioning of the glasses 400 as a reference, a plane perpendicular to the crossbeam of the glasses 400 and perpendicular to the ground is constructed as a reference plane; then, an arm surface is constructed based on the positioning information of the glove 100, wristband 200, and elbow pad 300. If the arm surface coincides with the reference plane (allowing for a certain error), the linear motor does not vibrate; if they do not coincide (allowing for a certain error), the linear motor is controlled to provide a prompt in a "vibrate for 5 seconds, then pause for 1 second" pattern. Afterward, the processor continuously collects position information and repeats the above judgment process to achieve dynamic feedback.

[0057] Technical principle: The billiards stroke correction device provided in this application is suitable for eye-level aiming and a horizontal hand-supported (flat-back) striking posture. For example... Figure 1As shown, the correct posture requires the upper body to lean forward smoothly, with the left hand's thumb and index finger, bridge of the nose, right wrist, and elbow all on the same plane, and this plane pointing towards the tip of the nose. As long as this spatial relationship is met, the user's overall posture will be correct, and the cue trajectory will be stable and straight. Through real-time vibration feedback from the linear motor, the user can gradually adjust their posture to the standard state, thereby forming correct muscle memory and achieving an effective and continuous corrective effect.
