[0001] 1. Field of the Invention

[0002] The present disclosure relates to an assisting tool for learning water sport; in particular, to a self-learning system for water sport users.

[0003] 2. Description of Related Art

[0004] Swimming is a popular sport enjoyed by the public. Typically in swimming, correct postures and movements have key effect on raising swimming technique and swimming speed. If the swimming movements are incorrect, the postures are poorly coordinated, leading to an increase in resistance during swimming and inefficiency of the exerted force to push forward, not only wasting unnecessary energy but also limiting the speed of the swimmer.

[0005] In order to improve swimming techniques, a swimmer typically hires a swimming instructor to raise the swimming technique and swimming speed. During the instruction by the swimming instructor, the swimming instructor can instruct the swimmer on correct swimming postures and techniques, and correct the incorrect parts of the swimmer so that the swimmer can obtain the correct swimming postures. Afterward, when the swimmer practices by himself or herself without the instruction of a professional instruction on the side, the swimmer cannot tell if his or her postures are correct or not during swimming. Therefore, an assisting tool for swimmers to observe whether his or her own swimming postures are correct or not, in order to assist the user to immediately correct the postures when practicing swimming by himself or herself, is an area that can be enhanced in swimming.

[0006] The self-learning system for water sport users of the present disclosure films the postures of the user during swimming. Afterward, the user can assess his or her own swimming movements along a learning software for water sport, to find out what to improve on, and obtain correct information on swimming from the learning software for water sport.

[0007] The present disclosure provides a self-learning system for water sport users, which includes a wearable camera device, a computer, and a learning data base. The wearable camera device includes a fixing element, a bearing element, and a waterproof camera. The fixing element is disposed on a human body. The bearing element is disposed on the fixing element. The bearing element is flexible and has adjustable length. The waterproof camera is disposed on the bearing element for filming the human postures during water sport. The recorded images are transformed by the waterproof camera into digital signals before being outputted. The computer receives and processes the digital signals, and then assesses the human postures in the water and provides information on learning swimming by using a water-sport learning module.

[0008] The present disclosure provides a self-learning system for water sport users, which includes a wearable camera device, a computer and a network learning platform. The wearable camera device includes a fixing element, a bearing element, and a waterproof camera. The fixing element is disposed on a human body. The bearing element is disposed on the fixing element. The bearing element is flexible and has adjustable length. The waterproof camera is disposed on the bearing element for filming the human postures during water sport. The recorded images are transformed by the waterproof camera into digital signals before being outputted. The computer receives and processes the digital signals, and is connected by network to the network learning platform, which can be a cloud platform. The network learning platform has an interactive water-sport learning module, which interactively assesses the human postures in the water.

[0009] In summary of the above, the wearable camera device allows the user to film his or her own posture in water sports, such that the user can view his or her own movements and postures after practice to assess whether they are correct, and use the information as reference for further self-adjustments. Additionally, the user can film the movements and postures during water sport and send them to the computer, and compare and analyze the postures with the correct postures from the learning data base, thereby obtaining a grade and level for his or her own postures and enabling himself or herself to correct the incorrect parts. Moreover, the user can also connect to the internet and use the network learning platform to compare with and analyze the correct postures from the interactive water-sport learning module provided by the manufacturer, thereby obtaining a grade and level for his or her own postures and learning more professional swimming information.

[0010] In order to further the understanding regarding the present disclosure, the following embodiments are provided along with illustrations to facilitate the disclosure of the present disclosure.

[0019] The object of the self-learning system for water sport users of the present disclosure is to film the postures during water sport by a camera worn on the body of the user, e.g. filming the postures of swimming, water ballet, or surfing. However the water sports are not limited to the above. Afterward, the user can view his or her own motion in the water, compare the recorded images with a software program of a water-sport learning module of the present disclosure, and obtain correct information for movement and posture by the assessment and suggested improvements given by the water-sport learning module.

[0020] Referring to FIG. 1 and FIG. 2, the present disclosure provides a self-learning system for water sport users, which includes a wearable camera device 1, a computer 2 and a learning data base 3. As shown in FIG. 1, the user wears the wearable camera device 1 during swimming. The wearable camera device 1 is disposed on the human body. The wearable camera device 1 of the present disclosure includes a water proof camera 11, a fixing element 12, and a bearing element 13. The wearable camera device 1 can film the postures of the motion in the water, and transform the recorded image signals into digital signals for output.

[0021] As shown in FIG. 2, after practicing the sport the user can transmit the digital signals of the image file recorded by the wearable camera device 1 to the computer 2, by using transmission device such as USB, data transmission cable, wireless transmission device or Bluetooth device, etc. The computer 2 can receive the digital signal transmitted by the wearable camera device 1 and process the digital signals so that the user can read the recorded images.

[0022] The learning data base 3 can be saved on CDs or other storage devices such as flash drives or discs. The learning data base is then read by the computer 2. The learning data base 3 has a water-sport learning module 31, which is a software program capable of assessing movement postures and providing related instructions and suggestions. The water-sport learning module 31 assesses the posture of a human body doing water sport and provides instructional information for swimming.

[0023] More specifically, the user can film the postures of water sport and transmit the image files to the computer 2, and then enter an assessment or comparison command, such that the water-sport learning module 31 grades the water-sport postures of the user doing water sport. For example, the water-sport learning module 31 can grade the postures of the swimmer from A to F, wherein A is a posture fully meeting the desired standards, B is a posture of an advanced swimmer, C is a posture of an intermediate swimmer, D is a posture of a basic-level swimmer, E is a posture of an introductory-level swimmer, and F is a posture of an entry-level swimmer. The postures of the swimmer can be graded from A to F by using the program of the water-sport learning module 31 to compare the image files of the water-sport postures.

[0024] Additionally, the water-sport learning module 31 can compare images to display incorrect aspects of the posture of a swimmer, e.g. the angle of motion of the arm is too large, the pedaling form of the leg is incorrect, etc., thereby promptly correcting the incorrect postures of the swimmer such that the swimmer can learn aspects of his swimming that needs to be improved upon. Moreover, the swimmer can input instructional commands, so that the water-sport learning module 31 provides relevant swimming instructions and a plurality of correct swimming postures. Also, incorrect postures of the swimmer can be addressed by playing the corresponding animation or image files with the correct swimming postures, thereby facilitating the user to learn the correct swimming postures.

[0025] Referring to FIG. 1 and FIG. 3, the present disclosure also provides a self-learning system for water sport users, which includes a wearable camera device 1, a computer 2, and a network learning platform 4.

[0026] As shown in FIG. 3, after the user wears the wearable camera device 1 during swimming, the digital signals of the image files recorded by the wearable camera device 1 is transmitted to the computer 2 by a transmission device. The computer 2 can receive the digital signals transmitted by the wearable camera device 1 and process the digital signals, such that the recorded images can be read by the user.

[0027] The user can use the computer 2 to connect to the internet and access the network learning platform 4 provided by the manufacturer. Namely, the user can access the website of the manufacturer and use the network learning platform 4 provided by the manufacturer. The network learning platform 4 can be a cloud platform and has an interactive water-sport learning module 41, also a network application, which can assess and analyze movement postures. The user can upload or download files through the interactive water-sport learning module 41 to interactively assess movement postures of water sport and obtain instructional information on swimming provided by the interactive water-sport learning module 41.

[0028] More specifically, the user can transmit the recorded image files of water sport postures to the computer 2, and then the user can connect to the network learning platform 4, upload the video or picture files of movement postures, and then enter the comparison or assessment command to prompt the interactive water-sport learning module 41 to grade the water sport posture of the user and assign a grade to the swimming posture of the user. Additionally, the interactive water-sport learning module 41 can display the incorrect aspects of the postures of the swimmer by comparing images, e.g. the angle of motion of the arm is too large, the pedaling form of the leg is incorrect, etc., thereby promptly correcting the incorrect postures of the swimmer such that the swimmer can learn aspects of his swimming that needs to be improved upon.

[0029] Moreover, the user can enter instructional commands, so that the interactive water-sport learning module 41 provides relevant swimming instruction, and plays the corresponding animation or image files with the correct swimming postures to address the incorrect postures of the swimmer, thereby facilitating the user to learn the correct swimming postures. Alternatively, professional swimming instructions can be conducted via the network learning platform 4, e.g. coaches on the national team level can provide swimming instructions so that the user can obtain more information on swimming.

[0030] Referring to FIG. 4 to FIG. 8, the wearable camera device 1 of the present disclosure is described in detail. The waterproof camera 11 is disposed on a body part by the fixing element 12 and the bearing element 13. The part of disposal can vary according to practical needs. In other words, the fixing element 12 can be disposed on the head, neck, back, waist, or other parts of the body, for filming the postures during water sport. For example, the waterproof camera 11 can be disposed on the head to film the swimming postures, and the lens 112 of the waterproof camera 11 can aim towards the arm, the legs, or the back to achieve the effect of filming.

[0031] The main purpose of the fixing element 12 is to fix the waterproof camera 11 on the body, therefore the fixing element 12 is an accessory which can be worn on the body. The fixing element 12 can be swimming goggles, head band, clip, headband, belt, or an accessory wearable on the body. However the type of fixing element 12 is not limited to the above. The bearing element 13 is disposed on the fixing element 12. The bearing element 13 is an element on which the waterproof camera 11 can adjust angles, so the bearing element 13 has flexibility, adjustable length, deformability or any adjustable quality, thereby allowing the bearing element 13 to bear and adjust the filming angle of the waterproof camera 11. The bearing element 13 can be an adjustable rod, a plastic unit, an elastic unit, a contracting unit, a soft metal tube or axis, etc. However, the type of bearing element 13 is not limited to the above.
