Example 1
Referring specifically to fig. 1, fig. 1 is a basic flow chart of a sitting posture correction control method according to the present embodiment.
As shown in fig. 1, a sitting posture correction control method includes the steps of:
s1100, acquiring detection information for detecting the distance of a preset body part of a target user, wherein the detection information comprises a first distance value and a second distance value between the head and the chest of the target user and a wristwatch worn by the target user respectively;
in order to detect the sitting posture of a target user, taking the sitting posture correction control method of the present invention as an example applied to a wristwatch of the target user, the system first detects the distance between the wristwatch and the head and chest of the target user, and when in implementation, the wristwatch has a general function of a common wristwatch, and the wristwatch further has a communication function, a vibration or voice reminding function, and comprises a watchband and a dial, wherein the dial and the watchband are respectively provided with a distance sensing device, and the wristwatch is worn by the wristwatch and left hand as an example, please refer to fig. 10, and fig. 10 is a diagram showing the relationship between the wristwatch and the human body in the sitting posture correction control method of the present invention, as shown in fig. 10, the wristwatch (wristwatch) is a1 and the human body is b1, the distance sensing device is respectively arranged on the dial of the wristwatch and one side of the wristwatch close to the human body, the distance sensing device arranged on the dial is used for detecting the distance of the head of the wearer (target user) from the wristwatch, and the distance of the distance between the wearer (target user) and the chest of the wristwatch is arranged on one side close to the human body. In an alternative embodiment, the distance sensing device may employ an ultrasonic detection sensor, which can emit and receive ultrasonic waves harmless to the human body, and the scenic spot distance between the objects can be obtained by combining the propagation speed of sound with the time interval of the emitted and received ultrasonic waves.
In an alternative embodiment, taking the example of a wristwatch worn on the left hand wrist of the target user, the general habits of a person writing are: with the right-hand pen, the left hand presses the written book or notebook, so, referring to fig. 10, the human head is located above the wristwatch dial ultrasonic sensor shown in fig. 10, and the human chest is located on the right side of the wristwatch watchband ultrasonic sensor shown in fig. 10. By utilizing the position relation between the human body and the watch when the human body writes, the detection of the distance between the head and the chest of the human body and the watch can be completed by combining the ultrasonic sensor arranged on the watch, wherein the distance between the watch and the head of the target user is a first distance value, and the distance between the watch and the chest of the target user is a second distance value.
S1200, inputting the first distance value and the second distance value into a preset sitting posture recognition model and acquiring posture information output by the sitting posture recognition model;
after acquiring a first distance value and a second distance value between the head and the chest of the target user and the wristwatch respectively, the system inputs the first distance value and the second distance value into a preset sitting posture recognition model, and when in implementation, the sitting posture recognition model is a preset convolutional neural network model for calculating and recognizing the posture information of the target user according to the distance between the head and the chest and the wristwatch. In an alternative embodiment, the working principle of the sitting posture recognition model is that the sitting posture of the target user is firstly judged according to the first distance value and the second distance value, wherein the sitting postures of the target user comprise a reading sitting posture and a writing sitting posture, and for the writing sitting postures, the general habit of a human body in writing is as follows: the right hand is used for holding a pen, and the left hand is used for pressing a written book or book, so that when writing is performed, the head of a human body is positioned above the ultrasonic sensor of the watch dial, the chest of the human body is positioned on the right of the ultrasonic sensor of the watch watchband, and at the moment, the ultrasonic sensors of the watch dial and the watchband have data, namely, a first distance value and a second distance value between the head and the chest of a target user and the watch respectively can be detected; for the reading gesture, please refer to fig. 10, the general habits of the human body in reading are: the two sides of the book are held by both hands, at this time, the head of the human body is positioned in front of the ultrasonic sensor of the wrist watch watchband shown in fig. 10, and the front of the ultrasonic sensor of the wrist watch dial is not shielded, at this time, only the ultrasonic sensor of the wrist watch watchband has data, the system can judge whether the target user is in a reading posture or a writing posture by detecting specific numerical values of the first distance value and the second distance value, for example, the dial ultrasonic sensor is set to be number 1 and the expression ultrasonic sensor is set to be number 2, when the data of the number 1 and the number 2 are both yes, the target user is judged to be the writing posture, and when the data of the number 1 is empty and the data of the number 2 is available, the target user is judged to be the reading posture.
After the sitting posture of the target user is identified according to the first distance value and the second distance value, the sitting posture identification model identifies and generates the gesture information of the target user according to the sitting posture of the target user and the first distance value and the second distance value, wherein the sitting posture identification model is a tool which is preset by a system and is used for identifying the gesture information of the user, and when the sitting posture identification model is implemented, an LSTM (Long Short-Term Memory) network can be used as a neural network model. LSTM networks control discarding or adding information through a "gate" (gate) to implement forget or memory functions. The "gate" is a structure that selectively passes information, and is composed of a sigmoid (S-shaped growth curve) function and a dot product operation. The output value of the sigmoid function is in the [0,1] interval, 0 representing complete discard, and 1 representing complete pass. The neural network model trained to be converged is provided with the classifier capable of recognizing the sitting posture of the human body, wherein the sitting posture recognition model comprises the neural network model, the neural network model comprises N+1 classifiers, and N is a positive integer.
Specifically, a classification result of the target user in the classifier is obtained by inputting the first distance value and the second distance value into a preset sitting posture recognition model, wherein the classification result comprises gesture information classification corresponding to the target user and Confidence (Confidence) of the gesture information classification. The confidence of gesture information classification refers to the percentage value of the detected information in more than one gesture information classification of the target user after screening and classifying the detected information detected by the target user through a sitting posture recognition model. Because the final obtained posture information corresponding to the target user is one type, the confidence of classification of each posture information of the same target user needs to be compared, for example, the system collects detection information of the target user, the detection information comprises a first distance value and a second distance value, the first distance value and the second distance value are input into a sitting posture recognition model, the confidence of classification of the sitting posture of the target user into the first sitting posture is 0.95, and the confidence of classification of the sitting posture of the target user into the second sitting posture is 0.65.
And then comparing the confidence coefficient with a preset first threshold value, and when the confidence coefficient is larger than the preset first threshold value, confirming that the gesture information classification result represented by the confidence coefficient is the sitting gesture of the target user. The preset first threshold is typically set to a value between 0.9 and 1. And (3) screening out the sitting posture with the confidence coefficient larger than a first threshold value as a final posture information classification result, namely confirming the sitting posture represented by the confidence coefficient. For example, when the preset first threshold value is 0.9, and the confidence that the sitting posture of the target user is classified into the first type of sitting posture is 0.95, the posture information represented by the first distance value and the second distance value in the detection information is the sitting posture of the target user because of 0.95> 0.9.
S1300, comparing the posture information with preset sitting posture specification information;
after receiving the gesture information output by the gesture recognition model, the system compares the gesture information with preset gesture standard information, wherein the gesture standard information is preset standard gesture information in the system, the standard gesture is a gesture form set by people, and when the gesture standard information is implemented, the gesture standard information can be gesture information published by an authoritative institution (such as a national medical college or world health organization), and whether the gesture of a target user is standard or not is judged by comparing the gesture information of the target user with the gesture standard information.
S1400, judging that the sitting posture of the target user is not standard and sending out a prompt when the posture information is not matched with the sitting posture standard information.
When the posture information is not matched with the sitting posture specification information, the system judges that the sitting posture of the target user is not specified, and at the moment, a prompt is sent out through a vibration or voice prompt function on the wristwatch. In an alternative embodiment, the system determines whether the posture information and the posture specification information are matched by comparing the posture information with the posture specification information to determine whether the posture information and the posture specification information are matched, in practice, whether the posture information and the posture specification information are matched may be determined by comparing a direct difference between the posture information and the posture specification information, for example, the system collects detection information of the target user, the detection information includes a first distance value and a second distance value, and then inputs the first distance value and the second distance value into a posture recognition model, the posture recognition model obtains the posture information of the target user according to the first distance value and the second distance value, specifically, for example, the confidence of the target user in classifying the posture to the first type of posture is 0.95%, the confidence of the target user in classifying the second type of posture is 0.65%, then the first type of posture is determined to be the posture information of the target user, and the posture specification information are compared to determine the difference between the first type of posture and the posture specification information, for example, the system sets the similarity between the first type of posture and the second type of posture and the posture specification information to be 95%, the second type of posture and the second type of posture is 80%, and the second type of posture is considered to be similar to the target user when the second type of posture is greater than the first type of posture is greater than the preset threshold (for example, the similarity between the first type of posture is equal to 90% of the target user and the second type of posture is compared to the preset to the posture is compared to the threshold is smaller than the threshold of the target posture is compared to the preset for the posture is compared to the first type of the posture is compared to the posture information is compared to the first type, the posture information of the target user is not matched with the sitting posture specification information, and the target user can be reminded of the sitting posture through vibration or through a voice reminding function.
In an optional embodiment, taking the example that the sitting posture correction control method is applied to a wristwatch, the wristwatch can be in communication connection with external terminal equipment (such as a mobile phone of a parent or a wristwatch) or a background server, a daily curriculum schedule and work and rest time of the target user can be set through the terminal equipment or the background server, and the wristwatch starts a sitting posture detection function in a time period set as reading and writing; when the sitting posture detection function is started, the watch (wristwatch) starts the dial and the ultrasonic sensor on the watch band to send out ultrasonic pulses (such as once in 2 seconds) at fixed time intervals; when only the ultrasonic sensor on the meter belt receives the reflected ultrasonic signal, the target user is considered to be in a reading posture at present; and when the watch dial and the watchband ultrasonic sensor both receive the reflected ultrasonic signals, the target user is considered to be in a writing posture.
When the target user is in a reading posture, the watch detects a reflected signal of an ultrasonic wave emitted from an ultrasonic sensor at the watchband, and calculates the distance between a human body (head) and the watch by a time difference between transmission and reception. When the distance is smaller than the distance (such as 40 cm) represented by the preset sitting posture standard information (the distance between the eyes of the human body and the book, namely the distance between the head of the human body and the watch when the user takes a reading posture), the user is judged to be out of standard in sitting posture, the watch vibrates, and corresponding icons with too close eyes to the target are displayed on a dial screen to remind the user of the sitting posture and the distance between the eyes and the book.
When the target user is in a writing posture, the watch detects reflected signals of ultrasonic waves emitted by ultrasonic sensors at the watchband and the dial plate, and the distances between the head and the chest of the human body and the watch are calculated through the time difference between the emission and the reception. When the distance detected by the ultrasonic detector on the dial is smaller than the distance between the eyes of the human body and the book (namely the distance between the head of the human body and the watch) in the preset writing gesture, for example, the distance between the eyes of the human body and the book is 30 cm in the writing gesture represented by the preset sitting gesture specification information, judging that the sitting gesture of the target user is not normal, vibrating the watch at the moment, and displaying the icon that the corresponding eyes are too close to the target on the screen of the dial; or when the distance detected by the ultrasonic detector on the watch band is smaller than the distance between the chest of the human body and the desk (namely the distance between the chest of the human body and the watch) when the distance between the chest of the target user and the watch is smaller than 10 cm, the watch vibrates, and an icon that the corresponding chest is too close to the target is displayed on the screen of the watch. The target user is reminded of the sitting posture and the distance between the chest and the desk.
Through correcting the writing sitting postures and the reading sitting postures, a target user can pay attention to the sitting postures of the target user when reading or writing, good sitting postures habit is formed, and problems of myopia, humpback, bad shape and the like are reduced.
According to the method, the device and the system, the detection information for detecting the distance of the preset body part of the target user is obtained, the detection information comprises a first distance value between the head of the target user and the worn wristwatch and a second distance value between the chest of the target user and the wristwatch, then the first distance value and the second distance value are input into the sitting posture recognition model to be calculated and generated, the gesture information of the target user is compared with the preset sitting posture specification information, so that whether the sitting posture of the target user is specified is judged, when the gesture information of the target user is not matched with the sitting posture specification information, the situation that the sitting posture of the target user is not specified is judged, a prompt is sent, whether the sitting posture of the target user is specified is judged through the distance between the head of the target user and the chest of the target user and the wristwatch, and then the bad sitting posture of the target user is corrected, and sitting posture recognition and correction accuracy can be effectively improved.
In an alternative embodiment, the sitting posture specification information includes writing specification sitting posture information, please refer to fig. 2, and fig. 2 is a schematic diagram of a specific flow chart for comparing writing sitting postures according to an embodiment of the invention.
As shown in fig. 2, step 1300 includes the following steps:
S1310, judging whether the target user is a writing sitting posture or not according to the posture information;
the sitting postures of the target user comprise reading sitting postures and writing sitting postures, and the comparison modes of different sitting posture data are different, and in the implementation, the system judges whether the target user is the writing sitting postures according to the posture information output by the sitting posture recognition model, specifically, the sitting postures of the target user can be judged through signals of ultrasonic sensors of a dial plate and a watchband of the wristwatch, for example, when a sitting posture detection function of the wristwatch is started, the wristwatch starts the ultrasonic sensors on the dial plate and the watch band, and ultrasonic pulses (such as one time in 2 seconds) are sent out at fixed time intervals; when only the ultrasonic sensor on the meter belt receives the reflected ultrasonic signal, the target user is considered to be in a reading posture at present; and when the watch dial and the watchband ultrasonic sensor both receive the reflected ultrasonic signals, the target user is considered to be in a writing gesture.
S1320, if so, comparing the first distance value and the second distance value with the writing standard sitting posture information.
When the system judges that the target user is in a writing sitting posture according to the posture information, the system compares the first distance value and the second distance value with writing standard sitting posture information, and when the system is implemented, the writing standard sitting posture information is standard information of the writing sitting posture carried in the sitting posture standard information, specifically, taking a wearer of the target user as a watch as an example, when the wearer is in the writing posture, the watch detects ultrasonic wave reflection signals sent by ultrasonic wave sensors at the watchband and the dial plate, and the distance between a human body and the watch is calculated through the time difference of transmission and reception, namely, the first distance value and the second distance value between the head and the chest of the target user and the watch. The system compares the distance between the head of the target user and the watch detected by the ultrasonic detector on the dial with the distance (such as 30 cm) between eyes of a human body and a book when the user is in a preset writing posture; in addition, the system compares the distance between the chest of the target user and the watch detected by the ultrasonic detector on the watch belt with the distance between the chest of the human body and the desk when the preset writing posture is performed, and judges that the sitting posture of the target user is not standard when the distance between the chest of the target user and the watch is smaller than the distance (such as 10 cm) between the chest of the human body and the desk when the preset writing posture is performed and when the distance between the head of the target user and the watch is smaller than the distance between the eyes of the human body and the book when the preset writing posture is performed.
In another alternative embodiment, the sitting posture specification information further includes a reading specification sitting posture information, please refer to fig. 3, and fig. 3 is a schematic diagram of a basic flow chart for comparing the sitting postures of the reading in accordance with one embodiment of the present invention.
As shown in fig. 3, following step 1320, the following steps are also included:
s1330, judging whether the target user is in a reading sitting posture or not according to the posture information;
the sitting postures of the target user comprise reading sitting postures and writing sitting postures, and the comparison modes of different sitting posture data are different, and in the implementation, the system judges whether the target user is the reading sitting postures according to the posture information output by the sitting posture recognition model, specifically, the sitting postures of the target user can be judged through signals of ultrasonic sensors of a dial plate and a watchband of the wristwatch, for example, when a sitting posture detection function of the wristwatch is started, the wristwatch starts the ultrasonic sensors on the dial plate and the watchband, and ultrasonic pulses (such as one time in 2 seconds) are sent out at fixed time intervals; when only the ultrasonic sensor on the meter belt receives the reflected ultrasonic signal, the target user is considered to be in a reading posture at present; and when the watch dial and the watchband ultrasonic sensor both receive the reflected ultrasonic signals, the target user is considered to be in a writing gesture.
