BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a block diagram showing the system of an embodiment of the motion recording apparatus of the present invention. As shown, the motion recording apparatus 100 of the present invention can be used to be equipped on, for example, a human, animal limb 11, or even a robotic arm, using at least one displacement sensor 20 to sense the displacement of a moving limb. And record it. From an application point of view, the motion recording apparatus 100 of the present invention is particularly suitable for recording motions that are more periodic, such as running, walking, riding a bicycle, and the like. Thus, in the example of Fig. 1, the wearing device 10 for equipping the motion recording device 100 on the limb 11 includes leggings for attaching the motion recording device 100 to the foot. However, it is known to those skilled in the art that the exercise recording device 100 can be worn on other limbs or body parts, or can be worn on shoes to obtain the same or similar motion recording effect.

The displacement sensor 20 is for sensing the displacement of the sensor 20 itself and outputting a sensing signal. Displacement sensors that can be used to provide motion history records, primarily displacement sensors that detect limb displacement. A sensor capable of providing a desired sensing function, including a commercially available three-axis displacement sensor, a six-axis displacement sensor or a nine-axis displacement sensor. Among them, the nine-axis displacement sensor is more suitable, because the sensor can provide acceleration, angular velocity and changes in geomagnetism due to motion, and the information provided is very suitable for accurately representing the motion and motion of the three-dimensional space.

The sensing data output by the displacement sensor 20 is generally only a data material called raw data, representing a relative change in the position of the sensor. The information represented includes the presence or absence of displacement, displacement direction, and displacement. The motion recording apparatus 100 of the present invention is coupled to the displacement sensor 20 by a data processing device 30 for receiving the sensing signal of the displacement sensor 20 and converting the sensing signal into displacement data of a specific format. In other words, the sensing signal output by the displacement sensor 20 is a component representing a change in the position of the sensor in a uniaxial direction of a sensor for a specific time. Taking a nine-axis sensor as an example, three axial acceleration values, three axial angular velocity values, and three axial magnetic values are output at the same time. The data processing device 30 provides a firmware interface to receive the sensing signal output by the displacement sensor 20, and after operation, becomes a motion description data representing the displacement sensor 20 in the three-dimensional space, in a specific format. Save it and become a sports record file. The motion record file contains data for the external motion image generating device to correspond to the position of the displacement sensor 20 to a reference point to generate a corresponding motion simulation animation.

Using an animation of one or more reference points in a three-dimensional space to produce an animation that depicts a three-dimensional motion is already a mature technique. A method suitable for use in the present invention includes reading an output of a displacement sensor, such as a nine-axis displacement sensor, such as a reading output in a CSV format, and computing a software such as a MATLAB numerical calculation to generate a sensor. Motion trajectory simulation map. With the position of the sensor as the reference point of the simulated graphic, the moving simulation animation of the simulated graphic in the three-dimensional space can be generated.

Another feasible method is to form a reading value of a nine-axis sensor output into an array data, take the vector value represented by the reading value of the accelerometer and the magnetometer, and change the angular velocity of the gyroscope into four elements. Quaternion to represent the rotation information of the sensor in the three-dimensional space. The receiver uses the quaternion rotation amount difference to calculate the sensor movement information after calibration, thereby realizing the motion description of one or more reference points in the three-dimensional space, and generating a gesture depicting the three-dimensional motion. Identify the purpose of the simulated animation or movie presentation. Other techniques for depicting the motion history of the displacement sensor 20 in a three degree space can be applied to the present invention.

In a preferred embodiment of the invention, the motion log file includes at least one starting reference point data and a plurality of displacement record data, each of which records and includes an associated time record. The initial reference point data is generally a description of the starting position of the motion recording device 100 when the data processing device 30 starts sampling the detection signal of the displacement sensor 20. In order to generate the initial reference point data, the user may be required to stop the motion for a predetermined time at the beginning of the recording, so that the displacement sensor 20 outputs the displacement amount with little or no change, and the current position. As the starting reference position. In other words, the data processing device 30 can set an initial program, and if the amount of the data acquired within a certain period of time after the start of recording is included, the amount of displacement of the specific time or longer is almost unchanged or substantially unchanged. The position of the displacement sensor 20 at that time is taken as the starting reference position. The description data of the location is used as the starting reference point data.

As for the multi-displacement record data, the displacement description data based on the initial reference position is used. The displacement description data is a plurality of data that changes with time. Therefore, the data processing device 30 needs to make each of the displacement record data corresponding to a specific time point when the motion record file is compiled; the time point may be an absolute time or a relative time. The corresponding method includes adding time data to each displacement record data, or providing a reference time for which time data can be calculated according to the sampling frequency. To this end, the data processing device 30 also provides time information related to the movement, such as time information generated by the timer.

After being processed by the data processing device 30, the prepared displacement record data is sequentially recorded in a motion record file and stored in the memory device 40. The memory device 40 is coupled to the data processing device 30 for storing processed displacement data. When the recording is completed, it becomes a single motion record file, representing the movement history recorded at a specific time.

The data processing device 30 having such a data processing function can be any commercially available microprocessor. As long as the software is converted and processed by the known technology, the sensing signal of the displacement sensor 20 can be captured and compiled into a suitable motion recording file. Fig. 2 is a view showing waveforms of displacement data of a motion record recorded by an embodiment of the motion recording apparatus of the present invention. As shown, the motion recording device uses a nine-axis displacement sensor that is worn on the upper of the athlete, senses the displacement of the displacement sensor when the athlete is running, and outputs a sensing signal. After the signal is processed, it becomes the waveform shown in FIG. 2. The data represented by such a waveform can be accepted by a variety of animation generating devices as a basis for generating motion recording animations.

In a preferred embodiment of the present invention, the data processing device 30 may also include a compression module (not shown) for compressing the amount of data of the motion log file. In a particular embodiment of the invention, the compression module reduces the amount of data in a manner of sample decimation. The data processing device 30 is configured to set a lower sampling frequency according to a displacement data sampling frequency parameter provided by an external device to reduce the amount of data. If the displacement sensor 20 uses a nine-axis sensor, the sampling frequency of the data processing device 30 can be greatly reduced, and the correct recorded data can still be obtained.

The motion recording device 100 of the present invention provides at least one control button 50 coupled to the data processing device 30 for controlling the data processing device 30 to begin and/or stop processing the sensing signals of the displacement sensor 20. Since the motion recording apparatus 100 of the present invention is used to record motion during movement, the user does not actually have time to perform any manipulation during the recording process. Therefore, the provided keys can be turned on and off as long as the data processing device 30 can be turned on to avoid power consumption. Therefore, it is also not necessary for the motion recording apparatus 100 to provide a display device. Of course, providing more than one button, or providing a display device, or even a sound playback device, is also indispensable. Further, it is also possible to operate the motion recording apparatus 100 with virtual keys without providing physical keys. In other words, the button 50 is not necessarily a physical button.

The motion recording apparatus 100 of the present invention provides a communication device 60 that is coupled to the data processing device 30 and the memory device 40 for exchanging data with the outside world. The primary function of the communication device 60 is to provide an external device 70 with the displacement data stored in the memory device 40. Moreover, in a preferred embodiment of the present invention, the communication device 60 is also adapted to receive the outside world, including the external device 70, setting the data processing device 30, such as setting the sampling frequency of the data processing device 30, and the like. In addition, the data processing device 30 can also receive parameters such as the type of motion represented by the specific motion record file and the wearing position of the motion recording device by the external device 70 through the communication device 60, and the data processing device 30 is attached to the specific motion record file. in. Such parameters can be referred to as motion parameters. In a preferred embodiment of the present invention, the data processing device 30 may include a motion parameter setting module (not shown) for accepting the motion parameters set by the external device 70 and storing the parameters in a specific motion record file. in.

For example, the exercise type parameter may include a type of exercise such as running, walking, riding a bicycle, and the like. The wearing position parameters may include parameters such as an upper/foot board, an ankle, a calf, a wrist, a forearm, and the like. Preset values can be set, such as the type of exercise for "running" and the wearing position of "shoe upper". Among them, the wearing position parameter is closely related to the generation of the motion simulation animation. Because the motion simulation animation is generated, the wearing position is used as a reference point or a reference point to control the movement display of the limb in the animation. It will be detailed below.

The communication device 60 can be a short-range wireless communication device or a wired transmission device. It is used to establish a connection with an external device 70 to exchange data. Any commercially available communication device can be used in the present invention. If the communication device 60 is a wireless communication device, it can be any short-range wireless communication device, such as a Bluetooth communication device 61; if it is a wired transmission device, it can be, for example, a USB transmission device 62. It is more suitable to use the industry standard communication protocol in application. However, the use of non-public communication specifications is also indispensable. As previously mentioned, the primary function of the communication device 60 is to provide the external device 70 with a motion log for displaying a motion recording animation on the display of the external device 70. Therefore, the communication device 60 can be constructed to provide a motion log file upon request from the external device when connected to an external device. This eliminates the user's complicated operation and facilitates the transmission of data files.

Since the motion recording apparatus 100 of the present invention is mainly provided for outdoor use, it is necessary to have the ability to operate for a relatively long time. The motion recording device 100 is provided with a power supply 80 for supplying power to the displacement sensor 20, the data processing device 30, the memory device 40, the communication device 60, and the like. The power supply 80 can be any commercially available power supply device, and typically includes a rechargeable battery, a power saving device (none of which is shown), and the like. A power converter (not shown) may also be additionally included for receiving power from the wired transmission device 62. For example, when the wired transmission device 62 is a USB transmission device, the power converter can obtain the power required by the motion recording device 100 from the USB pin to charge the rechargeable battery. The power supply device having the above functions is already a well-known technique, and a commercially available device can be used, and details are not described herein.

The motion recording apparatus 100 having the above-described elements, architecture, and functions can be worn on the wearer's upper by the wearing device 10. Before the athlete starts recording, the control button 50 is first pressed to start recording. The data processing device 30 of the motion recording device 100 enters the initial setting operation and acquires the starting reference point data from the displacement sensor 20 to set the initial reference position of the displacement sensor 20. If the motion recording device 100 includes a setting function, the user can set the control panel (not shown) of the motion recording device 100 or the external device 70. The parameters that can be set include the aforementioned motion type, wearing position, and the like. Thereafter, the athlete can start exercising, such as running, walking or cycling.

The type of exercise to which the present invention is applied is not limited in any way, and other sports such as boxing exercises such as boxing, squatting, ball games such as tennis, basketball, baseball, volleyball, and golf, swimming, etc., can utilize the motion recording apparatus 100 of the present invention. Make a record.

After the athlete starts to exercise, the displacement sensor 20 continuously senses its displacement and continuously outputs the sensing signal. The data processing device 30 samples according to a preset sampling frequency, and adds time information through calculation to generate displacement recording data to form a motion recording file, which is stored in the memory device 40. When the athlete completes the exercise or completes a recording, the button 50 is pressed again to instruct the data processing device 30 to close the motion log file. If you want to continue recording or changing the type of exercise or wearing position, you can still press the button 50 to record another sport record.

The data recorded by the above motion record file includes a three-dimensional spatial displacement history of at least one motion sensor at a specific time. According to the existing motion capture technology, the position of the motion sensor in the three-dimensional space as a reference point/reference point of the image sample in the motion capture system can be manipulated on the display. The display becomes a simulated animation. A device having the above or similar motion capture capability can be a dedicated motion capture device equipped with a data processor and display, and a transmission device that can retrieve data from the motion recording device. However, in a preferred embodiment of the present invention, the external motion image generating device is a general-purpose computer device, such as a personal computer or a tablet computer, a smart phone, etc., and is equipped with a motion animation to generate an application software program to utilize the computer device. The data processor, the display and the transmission device obtain a specific motion record file from the motion recording device, and generate an analog animation based on the motion record file after the operation, and display the image on the display. The external device 70 can also be a cloud server, equipped with a motion animation to generate an application software program, and obtain a motion record file through a terminal device, such as a personal computer or a tablet computer, a smart phone, etc., and generate a motion record file. The motion animation file is displayed on the display screen after the terminal device downloads.

Fig. 3 is a block diagram showing a system of a moving image generating device suitable for use in the present invention. As shown, the moving image generating device 70 is the external device shown in FIG. 1, and includes a communication device 71, a storage device 72, a processing circuit 73, and a display device 74. The communication device 71 provides a communication interface for receiving a motion log file sent by the motion recording device 100. As previously mentioned, the communication device 60 of the motion recording device 100 can be configured to automatically send a motion log file upon request by the external device 70. However, in a general application, a connection between the communication device 60 of the motion recording device 100 and the communication device 71 of the external device 70 is established after a certain negotiation procedure, and the motion image generation device 70 issues a request. This communication negotiation process between devices is already a mature technology, and experts in this industry are easy to achieve the necessary design to perform communication negotiation. Usually, if the data transmission between the two is through the wired transmission channel, the negotiation is started after the user connects the connector of the signal line to the signal line slot of the two devices. If it is a wireless communication channel, the negotiation is started after the user pairs the two devices.

The storage device 72 is coupled to the communication device 71 for storing the received athletic recording files. The storage device 72 can also be used to store at least one motion animation generation program, such as an animation generation program with motion capture capability. After the animation generation program is executed, the simulation animation of the limb movement can be generated according to the displacement record data in the motion record file. The motion image generating device or the motion image generating software may be provided with one or more sets of moving image template files, and each group of image template files includes a representative image of a plurality of body segments and reference point position information of at least one body segment. Fig. 4 shows a schematic diagram of a moving image displayed on the display of the moving image generating device. The image template 90 as shown includes the head and body 91 of the human body, two hands 92, 93, two thighs 94, 95, calves 96, 97, and two feet 98, 99. Among them, a reference point or reference points 98A and 99A are respectively indicated at the feet 98, 99. The reference point position in the image template corresponds to the starting reference point in the motion log.

In detail, in the application example of the present invention, the reference point or reference points 98A and 99A are set to positions where the motion recording apparatus 100 is worn on the player's footboard or upper. By using the above motion capture technology or other motion simulation image generation technology, the displacement record can be mapped to the reference points 98A, 99A according to the displacement record data recorded in the motion record file, and become the reference points 98A, 99A in space. The position change parameter, and guided by the reference points 98A, 99A, the template foot portions 98, 99 follow a certain motion rule to change the display position, or shape thereof, on the display device 74.

For example, if the exercise template 90 is a model of a human body, the range and direction of movement of each limb are limited by the joint and muscle structure, and cannot be freely rotated by the joint as a rotation axis. Considering these limiting factors, as well as the interlocking relationship between the segments of the limb, the display position, orientation, and shape of the limb on which the reference point is located on the display device 74 can be changed according to the displacement of the reference point. Related computing and display technologies are also known in the art and can be achieved using commercially available applications or processing devices. Details are not required to be described here.

The processing circuit 73 is connected to the storage device 72, and the motion animation generating program can be executed, and a motion recording file is obtained from the storage device 72, and a motion simulation image is generated according to the displacement data in the motion recording file, and displayed on the display device. 74. In a preferred embodiment of the present invention, the processing circuit 73 obtains a motion record file from the storage device 72, and an associated image template file, and generates a motion simulation image according to the displacement record data in the motion record file, and displays the Display device 74. As described above, the storage device 72, the processing circuit 73, and the display device 74 are generally storage devices, processing circuits, and display devices provided on a smart mobile device.

The image template files stored in the storage device 72 are individually available for the external motion image generating device to display an initial image of a motion type on the display. Taking human motion as an example, the initial image may be an image of a person standing up, and the various limbs 91-99 are connected to form a human body image. The initial image may vary depending on the type of exercise, but may be selected by the user's settings. The location of the motion recording device 100 may also vary from application to application, but may also be set by the user. The motion monitoring application can also directly set specific sport types and fixed wearing positions for ease of use. Under this condition, the processing circuit 73 can control the movement of the reference point according to the displacement data in the motion record file to drive the body passage in the image, and display according to the structural constraints of the human joints and muscles. Compliant movement, steering, and shape changes as a simulated image of motion.

As indicated above, the present invention relates to an athletic recording system. The motion recording device 100 is attached to a specific portion of the athlete's body, and has a displacement sensor 20 for sensing and recording the movement of the specific portion, which becomes a motion recording file, and is stored in the memory device 40. The communication device 60 supplies the motion log file to the motion image generating device 70, and displays the analog image of the player during the movement for a certain period of time on the display device 74 of the motion image generating device 70. Motion recordings are usually recorded accurately at high sampling frequencies, but can also be recorded at relatively low sampling frequencies. Recorded data sampled at a high sampling frequency can also be compressed in a down-converted manner.

The motion image generating device with motion capture capability generates a simulated image using a tracking technique to reproduce the recorded motion history. Provide a visual assessment of the observer to provide counseling or rehabilitation advice. The motion image generating device can further distinguish the types of motions to produce the correct motion simulation image. The motion type parameters can also be received from the motion image generating device 70, such as a smart phone or a personal computer or tablet, and settings are made in the motion recording device 100 to support different motion monitoring and recording. The invention does not need to wear a large and heavy camera, and does not need to move the camera with the mover to obtain correct motion picture recording.
