[0061] Therefore, the above is an introduction to the components of a synchronous live teaching device 100 integrating real-time video recording and screenshot functions provided by a preferred embodiment of the present invention, and then its usage characteristics are introduced as follows:

[0062] First, when the present invention is used, the teacher wears the headset 10 on the head, and uses the first joint portion 12 on the headset 10 and the upper second joint portion 214 of the camera 20 to form a ball head and a ball socket, so that the camera 20 can be rotated arbitrarily to adjust the direction (it can also be adjusted arbitrarily during the teaching process) to match the teaching content. Figure 6 As shown, the teacher passes the little finger 92 of one hand through the first finger sleeve 412 of the hand-worn controller 40, and passes the thumb 93 through the second finger sleeve 413, so that the wearing portion 411 is located on the back of the hand, and then combines the first fixing portion 414 with the second fixing portion 415, and the third fixing portion 416 with the fourth fixing portion 417, so that the hand-worn controller 40 can be firmly combined with the hand.

[0063] In this way, if Figure 7As shown, the teacher 94 can use the camera 20 on the headset 10 of the present invention to take pictures and conduct live teaching, so that students can watch on the student mobile phone 95, the student desktop 96 or the student tablet 97. They can also conduct actual operation exercises while watching on the student desktop 96 to achieve the purpose of live teaching.

[0064] In the camera 20, the light emitted by the illuminant 23 will be emitted through the rectangular wire frame 215 to form an expanded rectangular light frame 98 (such as Fig. 9 ), and illuminates the object, and the range within the rectangular light frame 98 is the image range during live broadcast. In this way, the teacher can know the current live broadcast image range at any time through the rectangular light frame 98 to avoid the situation where the live broadcast image is inconsistent with the teaching content. In addition, since the image captured by the camera lens 215 is only the range within the rectangular light frame 98, the rectangular light frame 98 will not be captured, which can avoid the problem of affecting the live broadcast image.

[0065] Then, during the live teaching process, the camera lens 22 of the camera 20 continuously transmits the captured images to the teacher's computer 91, and the live broadcast software is used for viewing by the student's mobile phone 95, the student's desktop 96, and the student's tablet 97 (such as Figure 8 As shown). If the teacher feels that a screen is more important and needs to be captured, the teacher can use the thumb to press the capture button 43 of the hand-worn controller 40, and the wireless transmitter 42 will transmit the capture signal to the teacher's computer 91, so that the teacher's computer 91 can store the capture screen in a designated location 99, so that it can be selected for students to watch after class or at the moment, so as to remind students of key points or give them homework. Or if the teacher feels that a video clip is more important and needs to be recorded, the teacher can use the thumb to press the record button 44 of the hand-worn controller 40, and the wireless transmitter 42 will transmit the recording signal to the teacher's computer 91, so that the teacher's computer 91 starts recording the current live video. After the teacher presses the record button 44 again, the recording stops, and the video clip is stored in the designated location 99, so that it can be selected for students to watch after class or at the moment, so as to remind students of key points or give them homework.

[0066] Therefore, the present invention can not only achieve the effect of live teaching, but also can use the rectangular light frame 98 emitted by the camera 20 to allow teachers to know the current live screen at any time to avoid the situation where the teaching content is inconsistent with the live screen. In addition, through the screenshot key 43 and the video key 44 of the hand-worn controller 40 in the present invention, teachers can operate in real time and conveniently when they feel the need to screenshot or record real-time video clips, so that after class or at the moment, there will be pictures or images to supplement the key points or reminders in real time, making it easier for students to understand.

[0067] In addition, although in the above embodiment, the first finger sleeve of the hand-worn controller is for the little finger to pass through. Fig.10 As shown, the first finger sleeve 412 of the hand-worn controller 40 can also be designed to allow the index finger to pass through, and of course can also be designed to allow other fingers to pass through, and both can achieve the same effect.

[0068] The above disclosure is only the preferred embodiment provided by the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes made by relevant technical personnel in the technical field based on the present invention should fall within the scope covered by the present invention.
