Of course, in other embodiments, the wearable device may include a smart ring, a handheld clicker, etc., which is not limited in this embodiment.

The smart bracelet can be worn on the user's wrist, and it is firm and not easy to fall off, especially suitable for younger students, such as children aged 3-8. Smart bracelets are especially suitable for classroom teaching scenarios for young children.

As shown in FIG. 1 , in this embodiment, in addition to the device main body 20 , the wearable device also includes a wearing part 10 , and the wearing part 10 is used to cooperate with the human body to fix the wearable device on the human body. For example, the wearing part 10 may be a strap of a smart bracelet, a ring holder of a smart ring, and the like.

In the following description of the embodiments, the wearable devices are all smart bracelets and are worn on the arm.

In order to facilitate user operation and information display, the device main body 20 also includes a wristband display screen 25 for displaying relevant information, such as the name of the student corresponding to the wearable device, prompt information, and the like. The display screen 25 of the wristband is arranged on the casing, and the display surface faces the outside of the casing. It can be connected with the controller and receive information to be displayed from the controller.

As shown in FIG. 2 , the controller is indicated by the CPU in FIG. 2 , which may be a control chip, which is not limited in this embodiment.

In this embodiment, the sound interaction collection module 21 includes a distance sensor 211 and a sound collector 212 .

The distance sensor 211 is used to detect the distance data between the wearable device and the designated part of the human body, the distance sensor 211 is connected with the controller, and sends the detected distance data to the controller.

Optionally, as shown in Figure 2, distance sensor 211 can be connected with controller through IIC interface circuit, can realize data transmission and control easily like this, has simplified connection complexity, makes the data transmission between controller and distance sensor 211 It is more convenient and reliable, and helps to reduce the volume.

The sound collector 212 is used to collect the sound data of the wearer, and is connected with the controller.

Optionally, the sound collector 212 may be a microphone or the like. Of course, different sound collectors 212 can be used according to different requirements. The sound collector 212 is connected with the controller through the CODEC interface module.

The sound collector 212 can start or stop collecting sound data according to the controller, and at the same time, the controller controls whether to process the sound data according to the distance data collected by the distance sensor 211 .

In this embodiment, it is applied in the classroom teaching process, and the voice interaction acquisition module 21 can be used to carry out pronunciation interactive exercises. For example, when using teaching videos for classroom teaching, the teaching videos can be used to show words or phrases that require students to perform pronunciation exercises Wait. The process for students to use the wearable device to practice pronunciation is as follows: the student moves the wearable device to the mouth, and speaks to the built-in sound collector 212 of the wearable device, and removes the wearable device from the mouth after the pronunciation is completed.

In this process, the wearable device utilizes the sound collector 212 to collect sound data (this sound data includes at least the student's pronunciation data), and the distance sensor 211 can collect the distance between the wearable device and the student's mouth. data. The controller receives the distance data collected by the distance sensor 211, and according to the distance data can determine whether the student has finished speaking, remove the wearable device from the mouth, and then judge when to terminate the sound collection.

For example, in a possible manner, when the controller judges when to terminate the sound collection based on the distance data, the controller compares the distance data collected by the distance sensor 211 with a preset distance threshold through a comparator therein.

When the comparison result indicates that the distance data is greater than the set distance threshold, it means that the user has moved the wearable device away from the mouth, based on which it can be judged that the user has completed a pronunciation exercise and the sound collection can be terminated.

Of course, in other embodiments, according to different needs, the controller can also use the distance data to control when the sound collector 212 starts collecting sound and when it stops collecting sound. For example, determine whether the student starts pronunciation practice by judging whether the detected distance data is less than the first set distance threshold, and when it is judged that the student starts pronunciation practice, control the start of the sound collector 212 to start collecting sounds. Determine whether the student has completed the pronunciation practice by judging whether the detected distance data is greater than the second set distance threshold. When it is judged that the student has completed the pronunciation practice, control the sound collector 212 to stop and complete the sound collection.

The controller determines whether the student has completed a pronunciation exercise through the distance data, and then controls when to stop collecting the sound, so that the sound data of the student in the process of interacting through the sound can be accurately collected, and excessive useless data can be avoided. Prevent excessive data processing pressure.

For the sound data collected by the sound collector 212, it can be stored in the local storage space in the wearable device, the sound data is analyzed and processed by the controller, and then the pronunciation of the student is obtained from the sound data, and the The pronunciation is compared with the preset standard pronunciation to judge whether the student's pronunciation is accurate. The judgment result can be displayed through the wristband display screen 25 .

Obviously, in this embodiment, after adding the distance sensor 211 to the wearable device, the distance sensor 211 is used to detect the distance change, and the effective sound data of the students can be accurately collected according to the distance change, and then the collected effective sound data can be properly processed. (such as speech recognition, etc.) to determine the content of the effective voice data, to determine whether the pronunciation of the student is accurate when performing pronunciation exercises according to the content of the effective voice data, or to determine whether the answer selected by the student when answering the multiple-choice question is determined according to the content of the effective voice data Correct, according to which the degree of knowledge mastery of the students can be determined.

Certainly, the device main body 20 may also include a wireless signal processor 23, which is connected with the controller, and sends or receives data according to instructions of the controller. For the sound data collected by the sound collector 212, it can be sent to other devices through the wireless signal processor 23, and the sound data is analyzed and processed by other devices, and then the pronunciation of the student is obtained from the sound data, and the pronunciation Compare with the preset standard pronunciation to judge whether the student's pronunciation is accurate. Other devices can send the judgment result back to the wearable device, which is received by the wireless signal processor 23 of the wearable device and displayed on the display screen 25 of the bracelet.

Optionally, the wireless signal processor 23 and the controller may be connected through an SPI interface to realize data transmission and interaction. The wireless signal processor 23 includes a 2.4G wireless signal transmitting unit connected to the controller, and/or a 2.4G wireless signal receiving unit connected to the controller, so as to realize data transmission and reception. Certainly, according to the different requirements of use, if only the data transmission function is needed, the wireless signal processor 23 can only include a 2.4G wireless signal transmitting unit; if only the data receiving function is needed, the wireless signal processor 27 can only include a 2.4G wireless signal unit. receiving unit.

In this embodiment, in order to be able to detect the body movements of the wearer to meet the requirements of different interaction methods, the body interaction collection module 22 includes a gyroscope sensor 221 and an acceleration sensor 222, and the gyroscope sensor 221 is used to detect where the wearable device is located. The rotation component of the body part; the acceleration sensor 222 is used to detect the acceleration value of the body part where the wearable device is located, and both the gyro sensor 221 and the acceleration sensor 222 are connected to the controller.

Both the gyro sensor 221 and the acceleration sensor 222 can be connected to the controller through the corresponding IIC interface circuit to realize data transmission. The wearable device measures the direction and speed of the wearer's body movements through the gyro sensor 221 and the acceleration sensor 222, and effectively detects the user's body movements, such as clapping hands, clapping legs, drawing circles, and swinging arms.

Specifically, the gyro sensor 221 at least collects the rotation component around the X axis and the rotation component around the Y axis of the body part where the wearable device is located, and sends the rotation component around the X axis and the rotation component around the Y axis to the controller; the acceleration sensor 222 At least collect the acceleration value in the X-axis direction and the acceleration value in the Y-axis direction of the body part where the wearable device is located, and send the acceleration value in the X-axis direction and the acceleration value in the Y-axis direction to the controller.

In this embodiment, it is applied in the classroom teaching process, and the body interaction acquisition module 22 can be used to perform selective interactive exercises. For example, when teaching videos are used for classroom teaching, the teaching videos can be used to display multiple-choice questions that require students to choose options, etc. . The process for students to use wearable devices to practice multiple-choice questions is as follows: by clapping hands, it is preset to choose A, and by clapping legs, it is said to choose B. Or, it is pre-set, to indicate the selection of A by drawing a circle on the arm, and to indicate the selection of B by reciprocating the arm. After showing the multiple-choice questions, students clap their hands or legs to indicate that they choose A or B.

Since the wearable device worn by the student includes the body interaction collection module 22, the gyroscope sensor 221 can be used to collect the rotation of the student's arm around the X-axis direction and the rotation around the Y-axis direction, and the acceleration sensor 222 can be used to collect the student's arm. The acceleration of the arm in the X-axis direction and the acceleration in the Y-axis direction can analyze the body movements of the wearer, and then determine the options selected by the students according to the body movements and the preset rules, so as to realize the student's Interactive question answering.

For example, the controller can determine the posture of the wearer's arm by analyzing the values of the X-axis rotation component and the Y-axis rotation component detected by the gyro sensor 221 , such as determining whether the wearer rotates the arm or not. The controller can determine whether the wearer swings the arm or not by analyzing the acceleration value in the X-axis direction and the acceleration value in the Y-axis direction detected by the acceleration sensor 222 . Whether the wearer's body movement is clapping hands or clapping legs can be determined by whether the wearer rotates and/or swings his arms, and then determines the wearer's answer choice for the question, and then determines the degree of knowledge mastery based on the wearer's answer data.

Of course, in addition to the aforementioned method of analyzing and processing the data collected by the gyro sensor 221 and the acceleration sensor 222 locally through the controller, the controller can also connect the gyro sensor 221 and the acceleration sensor 222 through the wireless signal processor 23. The data collected by 222 is sent to other devices for analysis and processing, and the analysis results can be sent back to the wearable device.

In addition, the controller can also judge when to stop sound collection based on the data collected by the gyro sensor 221 , the acceleration sensor 222 and the distance sensor 211 . For example, when the distance data collected by the distance sensor 211 is greater than the preset value, and it is determined according to the data collected by the gyro sensor 221 and the acceleration sensor 222 that the student has turned his wrist, the sound collection is terminated.

In this embodiment, the wearable device further includes a power supply unit 24 for supplying power to various components of the wearable device. The power supply unit 24 may be a storage battery, a button battery, or the like.

To sum up, when the wearable device is applied to the network teaching system, each student can wear a wearable device. When students practice pronunciation through voice or judge multiple-choice questions through limbs, they can The wearable device collects sound data and/or body data, and obtains the student's pronunciation information and option information from the collected sound data and/or body data, so as to determine the student's answering situation, and thus accurately grasp the student's learning situation and Learning progress and mastery of knowledge. It solves the problem that when interacting with questions in face-to-face classrooms, under the existing circumstances, the teacher can only name one or two students to answer. According to the mastery of the two students to determine the overall mastery of the students, it is difficult to accurately reflect each student's understanding of the problem. The problem of the actual mastery of knowledge.

In addition, the wearable device has a sound interaction collection module 21 and a body interaction collection module 22, which can adapt to various interactive forms, enrich classroom interaction types, enhance classroom teaching interactivity, further enhance classroom teaching fun, and improve teaching effects.

According to another solution of the present utility model, a smart classroom system is provided, which includes at least two wearable devices mentioned above.

The smart classroom system uses wearable devices to collect student interaction data in the classroom, for example: voice data when students answer pronunciation exercises and/or multiple-choice questions through voice, body data when students answer multiple-choice questions through body movements, etc., so that Students can have richer classroom interactions in the classroom teaching process. In addition, according to the collected interactive data, each student's learning progress and knowledge mastery can be obtained. Can address several students' questions.

According to needs, at least two wearable devices in the smart classroom system can be communicated and connected to send and/or receive data, so that data transmission can be performed between the wearable devices.

Optionally, in this embodiment, the smart classroom system further includes a server 400 . When the smart classroom system is relatively large, in order to facilitate data management, storage and analysis, etc., a server 400 can be set, and the server 400 can communicate with at least two wearable devices, and obtain data from each wearable device, and/or, send data to the wearable device. Wearable device sends data.

For example, the wearable device can directly send the collected voice interaction data and/or body interaction data to the server 400 so that the server 400 can obtain the data. At the same time, the server 400 may also send data to the wearable devices as required, for example, the server 400 sends an instruction to start and/or stop collecting sound and/or body movements to at least one wearable device.

Optionally, the intelligent classroom system can be used for intelligent network teaching. For example, as shown in FIG. ), sound equipment (such as speakers), use the control equipment to control the display equipment to display images, and control the voice equipment to play sound, so as to display the pre-recorded teaching video and realize the teaching to students. In this way, online unmanned teaching can be realized.

When the intelligent classroom system includes the server 400 and the client 500 at the same time, the client 500 can communicate with the server 400, and send data to the server 400, and/or receive data from the server 400, for example, the server 400 can send data to the client 500 Send the data it needs, such as student list, teaching video, etc.; the client 500 can communicate with each wearable device, and send data to each wearable device, and/or receive data from each wearable device; server 400 can send data to each wearable device through the client 500, and/or, receive data from each wearable device.

For example, the server 400 receives collected voice interaction data and/or body interaction data from at least one of the wearable devices; and/or, the server 400 sends the voice interaction data and/or body interaction data to the client 500 The interaction data is the result data after data analysis, or the information data of each of the wearable devices is acquired from the client 500 .

Certainly, the server 400 may also directly send data to each of the wearable devices, and/or receive data from each of the wearable devices.

When multiple clients 500 are included in the smart classroom, each client 500 can be connected to the server 400 for convenience of information management and unified control. Of course, in another situation, only the client 500 can be set, and the client 500 is respectively connected to the at least two wearable devices in communication, and sends data to the wearable devices, and/or, from the The wearable device receives data.

For example, each time a class is held, since the students attending the class may be different, in order to ensure the accuracy of the collected information, the client 500 may obtain the information of the students who will attend the class, such as names, before each class. Then establish a corresponding relationship between each student and each wearable device, such as establishing a corresponding relationship through random matching, or establishing a corresponding relationship in a certain order. Afterwards, the corresponding student information is sent to the corresponding wearable device through wired, wireless, etc., and the wristband display screen 25 of the wearable device is used to display the corresponding student information, and the student can choose the wearable device corresponding to himself accordingly. wear.

Since the client 500 is respectively connected to at least two wearable devices, it can send data to the wearable devices, and at the same time, the client 500 can also receive data from the wearable devices as needed. For example, the answer data collected by the wearable device can be directly sent to the client 500 .

In this network teaching scenario, since there is no teaching teacher (a teaching teacher refers to a teacher who mainly performs teaching work and knowledge explanations, there may be teaching assistants in this teaching scenario to maintain classroom order and assist teaching), then the classroom The interactivity of the teaching video may not be enough, and it is not conducive to testing the mastery of students. In order to solve this problem, interactive links can be added to the teaching video played, for example, adding after-class questions. When the after-school questions are played, the wearable devices worn by each student in the smart classroom system are used to collect the students' answers to the after-school questions. According to the collected answer information, the students' mastery of knowledge can be effectively determined. Of course, interactive exercises can also be interspersed in the middle according to the content of the teaching video. The working process of the smart classroom system is:

As shown in FIG. 3 , the smart classroom system includes a smart bracelet 100 , a classroom router 300 set in the classroom, a client 500 set in the classroom, a classroom display screen 600 , and a server 400 .

When the smart bracelet 100 joins a certain classroom, since the information of the classroom router 300 of the classroom is not stored therein or the information of the classroom router 300 of the classroom may be updated, therefore, the client 500 set in the classroom needs to set the classroom router The information of 300 is sent to each smart bracelet 100, so that it can be connected to the classroom router 300, so as to access the network through the classroom router 300.

According to the information, each smart bracelet 100 can communicate and pair with the classroom router 300 by using its wireless signal processor 23 to access the classroom router 300 .

Before a class starts in a certain classroom, the client 500 obtains the list of students for this class from the server 400 through a network (such as a private line network). The client 500 sends the student information in the student list to the smart bracelet 100 according to random distribution or other rules, so that each student is bound to a smart bracelet 100, so as to ensure that the collected student answer data can be accurately linked to the wearable bracelet. The smart bracelet 100 corresponds to the student, thereby ensuring the accuracy of the collected data.

When the class starts, the server 400 sends the pre-recorded teaching video to the client 500 in the classroom through the network, and the client 500 decodes the video and sends it to the classroom display screen 600 for display. When the server 400 determines that the teaching video is played to the interactive link (since the teaching video is pre-recorded, the server 400 can determine whether to play to the interactive link according to the playing time of the teaching video), the server 400 sends a "activation intelligence" to the classroom router 300 through the network. Bracelet 100 instructions", the classroom router 300 sends it to each smart bracelet 100 through the WIFI network. The sensors 222 and the like collect data.

For example, when performing pronunciation exercises in the interactive part of the teaching video, the video can guide students to lift the smart bracelet 100 to their mouths and pronounce according to the content shown in the video, such as pronouncing English words, etc. At this time, they can use voice interaction The collection module 21 collects the voices of the students. For young children, because they often pronounce a word continuously, the collected voice data is continuous and messy, making it impossible to judge whether the student's pronunciation is accurate or not. For this reason, students can be instructed during guidance Every time a pronunciation is finished, the wrist is turned over, so that the distance sensor 211 in the sound interaction acquisition module 21 of the smart bracelet 100 detects that the distance between it and the designated part of the human body (such as the mouth) will change, and the smart bracelet 100 can When the distance exceeds a predetermined value, it is judged that a reading is completed.

When multiple-choice questions are given in the interactive part of the teaching video, the video can guide students to clap their hands to indicate that they choose A, and clap their legs to indicate that they choose B. In order to ensure the accuracy of the collected information and minimize the useless information collected, the server 400 can send an instruction to activate the smart bracelet 100 to the smart bracelet 100 after playing the topic and the guide instructions, so that it can activate the body interaction collection module 22 and Collect limb data (such as upper limb movement data, lower limb movement data, and/or head movement data, etc.). According to the collected data, the action of the wearer of each smart bracelet 100 can be judged, such as whether it is clapping hands or clapping legs, and then the result of the student's choice can be judged. The analysis process based on the collected body interaction data can be performed by the smart bracelet 100 , or the smart bracelet 100 can directly send the collected data to the server 400 for analysis by the server 400 .

According to needs, the smart bracelet 100 can analyze the data of each student's pronunciation or body movements according to the collected data to determine the answer or the answer of the choice, and then send these data to the server 400 through the classroom router 300, and the server 400 will send these data to the server 400. The result data is sent to the client 500 in the classroom, and displayed on the classroom display screen 600 in the classroom. Alternatively, the smart bracelet 100 can also directly send the collected data to the server 400, and the server 400 analyzes the data to obtain the pronunciation data or the answer of the body selection of each student, and sends the resulting data to the client in the classroom 500, use the classroom display screen 600 in the classroom to display.

In order to save energy, reduce the useless interference data collected by the smart bracelet 100, and improve the validity of the data, during the video teaching process, after playing the guide instructions for each question, the server 400 sends an instruction to activate the smart bracelet 100, and the smart bracelet During the predetermined period of time when the ring 100 receives the command to activate the smart bracelet 100, it is in an activated state and collects the data of the students. After the predetermined time has passed, the smart bracelet 100 goes into sleep mode and no longer collects student data. Until the instruction to activate the smart bracelet 100 next time is received.
