It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

A same-screen educational device as shown in Figure 1 includes a teacher computer, a large-screen display, a screen-sharing device, and a somatosensory interaction device, and the screen-sharing device is respectively connected to the teacher computer, the large-screen display, and the somatosensory interaction device. The same screen device includes a wireless communication module, a data processing unit and an input module, the data processing unit is used to receive the teaching content uploaded by the teacher computer, and displays it on the large-screen display in real time through the input module, and the data processing unit also It is used to receive the gesture command of the somatosensory interaction device, and act on the teacher computer through the wireless communication module. The teacher's computer is generally a terminal device such as a computer, a tablet computer, and a mobile phone. The teacher's computer is used to display teaching content. At the same time, by using the same screen device, the screen displayed on the teacher's computer can be displayed on the large-screen display on the same screen. The same screen device realizes the same screen display of the teacher's computer and the large-screen display. In the process of use, first display the content to be displayed through the teacher computer, the wireless communication module of the same screen device establishes a communication connection with the teacher computer, and receives the screen content displayed by the teacher computer in real time, and the data content received by the wireless communication module, through the processing unit Perform data analysis and processing, and upload to the large-screen display through the input module for display on the same screen. At present, many multimedia teaching all-in-one machines use infrared remote sensing technology to control the content displayed on the screen. Due to the limitations of infrared remote sensing technology in communication, it often happens that the large-screen display cannot receive control signals; The fun of using screen education equipment. The same-screen educational device in this embodiment implements control of a large-screen display by setting a somatosensory interaction device and using somatosensory technology. Somatosensory technology is that people can directly use body movements to interact with surrounding devices or environments without using any complicated control equipment, allowing people to interact with content in an immersive way. The somatosensory interaction device of this embodiment utilizes the inertial sensing technology of the somatosensory technology. Similar to somatosensory games, there are three single-axis accelerometers and three single-axis gyroscopes in the somatosensory interactive device. The accelerometer detects the acceleration signal of the three-axis independent object in the carrier coordinate system, and the gyro detects the acceleration signal of the carrier relative to the navigation coordinate system. The angular velocity signal measures the angular velocity and acceleration of the object in three-dimensional space, and uses this to calculate the attitude of the somatosensory interactive device. In this way, during the teaching process, the teacher can use gestures to output the page-turning control signal by wearing or holding the somatosensory interactive device. After receiving the control signal, the data processing unit sends the control signal to the teacher computer through the wireless communication module to control the teacher computer. If the displayed content is turned over, the large-screen display will display the content displayed by the teacher's computer on the same screen in real time through the same screen device. The somatosensory technology is an existing technology, and will not be described in detail here. It should be noted that the somatosensory interaction device in this embodiment can also use the optical sensing technology of somatosensory technology to recognize the user's gesture, obtain the human body image through the three-dimensional camera, and obtain the user's gesture control signal by analyzing the image. Realize the page turning control of the display content of the large-screen display. Optical sensing technology is one of the more mature somatosensory technologies, so I won't go into details here.

Specifically, the data processing unit includes a video decoding unit and an audio decoding unit. The video decoding unit is used for video decoding the video data in the received data; the audio decoding unit is used for audio decoding the audio data in the received data. The input module includes three interfaces: VGA, HDMI, and DVI. Multiple interfaces of different video transmission standards are used to meet the transmission requirements of different video transmission standards. The wireless communication module is one or more of Bluetooth and WiFi. WiFi and Bluetooth are the wireless communication methods of most mobile terminal devices at present. Since most of the teacher computers use mobile phones, tablet computers, etc., the wireless communication module uses Bluetooth or WiFi to meet the needs of most terminal devices.

In addition, the screen sharer also includes a storage unit. The storage unit is used to store the teaching content uploaded by the teacher's computer, so that when the teacher's computer is disconnected from the same screen device, the input module can still display the teaching content stored in the storage unit on the large-screen display. The same-screen educational device of the embodiment is more flexible in use. There are multiple large-screen displays, and each of the large-screen displays is connected with the same-screen device. In some larger classrooms, due to teaching needs, it may be necessary to set up multiple large-screen monitors so that students can watch the display content of the large-screen monitors more clearly. In addition, it should be noted that when the content of different pages needs to be displayed separately, the teaching content stored in the storage unit can be used to directly call and display, which is convenient for multiple screens to display different content at the same time.
