Referring to FIGS. 1 to 5 , the present embodiment provides a simulated virtual classroom 100 . The simulated virtual classroom 100 includes a servo device 1 and two wearable devices (ie, the first wearable device 2A and the second wearable device in FIG. 1 ). device 2B). The simulated virtual classroom 100 can use the servo device 1 as a relay station for data, and further receive and transmit the data to the two wearable devices through a network communication technology (eg, a wireless network), so that the two wearable devices can be transmitted. The wearable device can obtain the same data in real time to construct a synchronized virtual reality screen, thereby realizing the effect of virtual reality teaching. It should be noted that the terms such as "simulation" and "construction" mentioned in this embodiment are generated by data processing using a device capable of data operation or calculation. Next, the components of the simulated virtual classroom 100 and their connection relationships will be introduced below.

As shown in FIG. 1 , the servo device 1 includes a database module 11 and a servo communication module 12 electrically coupled to the database module 11 . The servo communication module 12 is a device capable of receiving and sending network communication. The aforementioned network communication technology in this embodiment takes a wireless network as an example, and can be implemented for the database module 11 Push technology (server push). The database module 11 is composed of a storage unit 111 and a processing unit 112 in this embodiment, and in practice, the storage unit 111 may be a traditional hard disk (HDD) or a solid-state hard disk ( SSD) and other storage devices, and the storage unit 111 pre-stores a classroom environment data and a plurality of operand data each having an event parameter, and the processing unit 112 can be used to manage the data distribution of the storage unit 111, Basic operations, command control, etc.

It should be noted that, the database module 11 can be used to add or adjust classroom environment data and operator data by using an electronic device (eg, a computer or a mobile phone) according to actual needs. Of course, the event parameters of each of the operator data can also be adjusted and increased by the aforementioned electronic device.

As shown in FIG. 2 and FIG. 3 , the two wearing devices can be respectively used for one person to wear. In practical use, the person on which one of the wearable devices is worn is a lecturer (or teacher), and the person on which the other wearable device is worn is a student (or student). That is to say, the number of wearable devices in the simulated virtual classroom 100 can be adjusted according to actual needs, but the number is at least two.

For the convenience of description, this embodiment is described with two wearing devices, and the wearing device for the instructor is further defined as a first wearing device 2A. The wearing device 2 is further defined as a second wearing device 2B. The components of the first wearable device 2A and the second wearable device 2B are substantially the same. Therefore, the first wearable device 2A and the second wearable device 2A are described below by taking the first wearable device 2A as an example. The components of the wearable device 2B and their connection relationships are described, and the different components of the two will be introduced later.

As shown in FIGS. 1 and 2 , the first wearable device 2A includes a basic sensing module 21 , a data storage module 22 electrically coupled to the basic sensing module 21 , and a data storage module 22 electrically coupled to the basic sensing module 21 . A communication module 23 of the data storage module, a computing module 24 electrically coupled to the communication module 23 and the data storage module 22, and a computing module 24 electrically coupled to the The operation module 25 and a virtual reality module 26 are provided.

The basic sensing module 21 can acquire the posture and voice of the person (which will be described by the lecturer below) to generate a person data. Further, the basic sensing module 21 is composed of a variety of sensors, so as to obtain a variety of different parameters to be combined into the personnel data, and used for the subsequent simulation (or construction) of the computing module 24 For virtual reality.

Specifically, the basic sensing module 21 includes a three-axis attitude sensing unit 211 and a face scanning unit 212 in this embodiment. Wherein, the three-axis attitude sensing unit 211 can use a three-axis gyroscope (Gyroscope) or a three-axis accelerometer (Three-axis accelerometer) in practice to obtain an attitude parameter of the lecturer, and the attitude parameter is ideal It must have dynamic information of the instructor's head, hands, and feet. In practice, the face scanning unit 212 can use an infrared dot-matrix photographing device (eg, True-Depth Camera), and can scan the lecturer's facial features in real time and generate a facial feature parameter, which means that the facial feature parameter is all the facial features. Describe the dynamic changes of the lecturer's eyes, nose, and mouth. In other words, the personal data includes the facial features parameters and the posture parameters, but the present invention is not limited thereto.

For example, in other non-illustrated embodiments of the present invention, the three-axis attitude sensing unit 211 can also be replaced with a dynamic image recognition unit, and the dynamic image recognition unit can be obtained by using the image changes of the lecturer The attitude parameter; or, other sensors are added to the basic sensing module 21 to improve the types of parameters included in the personnel profile.

In addition, the data storage module 22 can be used to store any data. Specifically, the data storage module 22 can store data without network communication, wherein the data stored in the data storage module 22 includes an initial environment data, and the initial environment data is It is used for the computing module 24 to simulate (or construct) an initial virtual environment T5, wherein the initial virtual environment T5 can be understood as a waiting virtual space for waiting for a network communication connection.

In practice, the initial environment data in the data storage module 22 may be preset, or may be obtained by an environment scanning module 27 of the first wearable device 2A to obtain the actual environment in which the lecturer is located. generated, wherein the environment scanning module 27 is electrically coupled to the data storage module 22 . For example, if the initial environment data is preset, the initial virtual environment T5 may be a white virtual space (as shown in FIG. 4 ) and has a virtual operator (described later); otherwise, if all When the initial environment data is generated by the environment scanning module 27, the initial virtual environment T5 simulates the actual environment scene where the lecturer is located. It should be noted that the initial virtual environment T5 can enable the lecturer (and the personnel) to adapt to the visual experience and operation experience of the virtual environment in advance, and can also be used to allow the lecturer to select the content to be uploaded (ie, augmented). Operator data (more on this later).

The communication module 23 is a main component for providing the first wearable device 2A with network communication, and the communication module 23 can perform two-way reception and transmission with the servo communication module 12 . Accordingly, the communication module 23 can send the personnel data to the database module 11 so that the servo communication module 12 can send the data to the second wearable device 2B.

It is worth noting that the communication module 23 must be authorized or invited to transmit the personnel data to the database module 11 so as to perform the subsequent push broadcasting technology. Specifically, after the communication module 23 receives an invitation identification parameter through network communication, the communication module 23 can send and receive the data in the database module 11 via the servo communication module 12 . Therefore, if the communication module 23 does not receive the invitation identification parameter, the computing module 24 of the first wearable device 2A can only obtain data from the data storage module 22 for simulation.

The computing module 24 uses an image processing chip (eg Cupola360) in this embodiment, but the present invention is not limited thereto. The computing module 24 can use the initial environment data to simulate the initial virtual environment T5, and further use the personnel data to generate a virtual person in the initial virtual environment T5 (hereinafter, the virtual lecturer T3 and the virtual person student T4); or, the computing module 24 can use the classroom environment data to simulate a virtual classroom T1 (as shown in FIG. 5 ), and further use a plurality of the operator data and the personnel The data simulates a plurality of virtual operators T2 and the virtual lecturer T3 (or virtual student T4 ) in the virtual classroom T1 .

It should be noted that, when the communication module 23 receives the invitation identification parameter, the computing module 24 switches from simulating the initial virtual environment T5 to simulating the virtual classroom T1, and in the virtual classroom T1 simulates the virtual instructor T3. That is to say, when the computing module obtains the classroom environment data, it stops simulating the initial virtual environment T5, and merges the personnel data into the classroom environment data for simulation.

The operation module 25 is a gesture sensor glove in this embodiment, but the present invention is not limited thereto. The operation module 25 can sense the hand position of the lecturer to generate a hand posture data (for example, the coordinate change of fingers), and the operation module 24 can use the hand posture data in the virtual classroom T1 simulates any one of the virtual operators T2 to execute a trigger event. Wherein, the trigger event is simulated and generated by the computing module using the event parameter.

For example, as shown in FIG. 5 , wherein the two virtual operators T2 are a virtual chalk T21 and a virtual blackboard T22 , the lecturer can take the continuous gesture of “pick up the chalk and write on the blackboard” in reality Let the operation module 25 obtain the specific hand posture data, so that the virtual lecturer T3 in the virtual classroom T1 picks up the virtual chalk T21 and generates a writing sound in front of the virtual blackboard T22 and the virtual blackboard T22 generates a trigger event for writing lines.

The virtual reality module 26 is virtual reality glasses in this embodiment, and has the function of playing audio, but the present invention is not limited thereto. The virtual reality module 26 can present the virtual lecturer T3 and the trigger event in the virtual classroom T1 or the initial virtual environment T5.

In a preferred case, the first wearable device 2A may include a scan modeling module 28 electrically coupled to the data storage module 22, and the scan modeling module 28 can scan objects to generate a An extended item data of event parameters, the extended item data can be stored in the data storage module 22 and used by the computing module 24 to generate an extended operator in the initial virtual environment T5 (see also is the augmented virtual operator T2). That is, the lecturer (or the student) can use the scan modeling module 28 to augment the virtual objects (ie, virtual operators) in the virtual classroom T1. Of course, in other not-shown embodiments of the present invention, the expanded item data can also be created by other methods, such as 3D drawing, or imported from an open 3D object database through the Internet . The human-object interaction functions required on the augmented virtual objects are set in real time by the creators of the virtual objects. For example, a virtual mobile phone is augmented, and a virtual button on the virtual mobile phone is set to be touchable to activate the screen of the virtual mobile phone to display a multimedia content. .

It is worth noting that when the communication module 23 of the first wearable device 2A receives the invitation identification parameter, the communication module 23 can use network communication to send the information via the servo communication module 12 The expanded item data is stored in the database module 11, and the servo communication module 12 can send the expanded item data to the data storage module 22 of the second wearable device 2B for storage. Accordingly, when the virtual object augmented by the lecturer (or the student) can be authorized to enter the virtual classroom T1, it is synchronously stored in the database module 11 to facilitate the servo communication module 12. For subsequent pushing and synchronizing the screen of each of the wearable devices 2. Generally speaking, the action of the instructor selecting whether to upload the expanded item data to the database module 11 for storage will be selected in the initial virtual environment T5.

The above are the components and the connection relationship between the components in the first wearing device 2A and the second wearing device 2B. Next, the different components of the first wearing device 2A and the second wearing device 2B and their connection relationships will be introduced.

As shown in FIG. 2 , generally speaking, the first wearable device 2A is preset to be worn by a manager (ie, a lecturer), so the first wearable device 2A further includes an electrical coupling to the A data management module 29 of the communication module 23, the data management module 29 can send a screening command to the servo communication module 12 through the communication module 23, so as to control the servo communication module 12 from All or specific data sent by the database module 11 .

For example, it is assumed that the total number of the plurality of operating object data is three, and the corresponding virtual operating objects T2 are a microscope, a wrench, and a welding torch. When the content that the lecturer wants to teach is "factory operation", the lecturer can use the data management module 29 to select the operator data corresponding to the microscope in the database module 11 and cannot be communicated by the servo Sent by module 12. That is to say, in the virtual classroom T1, there are only the virtual operator T2 corresponding to the wrench and the virtual operator T2 corresponding to the welding torch. Accordingly, the data management module 29 can effectively simplify the number of virtual operators existing in the virtual classroom T1 , thereby improving the concentration of the students and reducing the computing burden of the computing module 24 .

Similarly, the lecturer can also use the data management module 29 to selectively set whether the virtual operator T2 allows a specific person (that is, a person wearing a wearable device) to see outside the virtual classroom T1 , the content of the trigger event of the virtual operator T2 (for example, zoom, displacement, rotation, special effects, content, etc.) can also be flexibly regulated to increase flexibility.

For example, as shown in FIG. 6 , it is assumed that when the mid-term exam is conducted in the virtual classroom T1, the lecturer can use the data management module 29 to set the display time of the content of the virtual exam paper T2, so that all The content of the virtual test paper T2 will only be displayed at a specific time. Of course, the management data module 29 can also realize data transmission between any virtual student T4 in the virtual classroom T1 and other virtual students T4, such as images, sounds, or data.

That is to say, the lecturer (ie, the administrator of the virtual classroom T1) can set the two-way or multi-way interaction authority between each person and the virtual operator T2 through the data management module 29, so that The interaction between people and virtual operators, people and people, and virtual operators and virtual operators can be effectively controlled.

As shown in Figure 3, in the special case of the prevalence of infectious diseases, it is also very important for the lecturer to know the physical condition of the students during the lecture. The basic sensing module 21 of the second wearable device 2B further includes a physiological monitoring unit 213 . Specifically, the physiological monitoring unit 213 can sense the physiological condition of the student and generate a physiological parameter, and the physiological parameter is used by the communication module 23 of the second wearable device 2B via the servo communication module The group 12 is transmitted to the virtual reality module 26 of the first wearable device 2A for presentation.

That is, the lecturer can know the physiological condition of the student wearing the second wearable device 2B in the virtual classroom T1 through the first wearable device 2A (for example, in the virtual classroom T1 Physiological values are displayed on the interface), so that the student can be sent to the doctor immediately when there is any abnormality in his body. Of course, except in special cases where infectious diseases are prevalent, the physiological parameters can also be used as the instructor to determine the degree of concentration of the trainee. For example, when the trainee's heart rate is too stable for a long time, the instructor Students may fall asleep.

In practice, the physiological monitoring unit 213 includes a body temperature sensor and a heart rate sensor, the body temperature sensor can detect the body temperature of the student to generate a body temperature value, and the heart rate sensor Then, the heartbeat of the trainee can be detected to generate a heartbeat value, that is, the physiological parameter has a body temperature value and a heart rate value in this embodiment, but the present invention is not limited to this. For example, the physiological monitoring unit 213 can timely add a blood pressure sensor or a breathing sensor according to actual needs, so as to increase the physiological information that can be presented by the physiological parameters.
