Description

A synchronous live teaching device integrating real-time recording and screenshot functions

This creation is related to the related equipment of live teaching, and more specifically refers to a synchronous live teaching device that integrates real-time recording and screenshot functions.

Press, due to the large-scale global epidemic of "serious special infectious pneumonia" in recent years, in order to reduce the probability of infection and reduce close contact between people, it has become a necessary measure. However, in order to take into account the teaching rights of students, most of the current teaching of various subjects adopts remote video broadcast teaching. However, because teachers' live video recording equipment is generally fixed on the desktop or other fixed objects, during the teaching process, the live broadcast screen may not match the teaching content, which makes it difficult for students to understand the teaching content. Furthermore, since the live video recording equipment records images continuously, although there will be a single image file stored in the electronic device (such as a computer) during the live broadcast, the teacher may need to focus on the partial screen or partial image, and Students may also need to repeatedly watch part of the screen or part of the image. At this time, they can only find the required segment in the image file recorded continuously for a long time, and the process of searching will waste a lot of time, resulting in learning difficulties. Efficiency is reduced.

Therefore, the above is an introduction to the components of a synchronous live teaching device 100 that integrates real-time recording and screenshot functions provided by a preferred embodiment of the present creation, and then its use characteristics are introduced as follows: First of all, when this creation is used, the teacher wears the headgear 10 on the head, and uses the first joint 12 on the headgear 10 and the second joint 214 on the camera 20 to form a ball The combination of the head and the ball socket can be freely rotated to adjust the direction of the camera 20 (it can also be adjusted arbitrarily during the teaching process) to match the teaching content. Next, as shown in the sixth figure, the teacher passes the little finger 92 of one hand through the first finger cover 412 of the hand-worn controller 40, and the thumb 93 passes through the second finger cover 413, so that the The wearing part 411 is located on the back of the hand, the first fixing part 414 is combined with the second fixing part 415, and the third fixing part 416 is combined with the fourth fixing part 417, so that the hand-worn controller 40 can be stable attached to the hand. In this way, as shown in FIG. 7, the teacher 94 can use the camera 20 on the creative headset 10 to capture images for live teaching, so that the students can watch it on the student's mobile phone 95, the student's desktop computer 96 or It can be viewed by the student's tablet 97, and can also be viewed on the student's desktop 96 while performing actual operation exercises, so as to achieve the purpose of live teaching. The light emitted by the light-emitting body 23 in the camera 20 will be emitted through the rectangular wire frame 215 to form an expanded rectangular light frame 98 (as shown in the ninth figure), and illuminate the object , and the area within the rectangular light frame 98 is the image area during live broadcast. In this way, the teacher can know the current live image range through the rectangular light frame 98 at any time, so as to avoid the situation that the live broadcast image does not match the teaching content. In addition, since the picture captured by the photographic lens 215 is only within the range of the rectangular light frame 98, the rectangular light frame 98 is not captured, and the problem of affecting the live broadcast picture can be avoided. Then, during the live teaching process, the photographing lens 22 of the camera 20 continuously transmits the captured image to the teacher's computer 91, and the live broadcast software is used for viewing on the student's mobile phone 95, the student's desktop computer 96, and the student's tablet 97. (as shown in Figure 8). If the teacher thinks that there is a more important screen and needs to take a screenshot, the teacher can press the screenshot button 43 of the handheld controller 40 with his thumb, and the wireless transmitter 42 will transmit the screenshot signal to the teacher's computer 91, so that the The teacher's computer 91 stores the screenshot in a designated location 99, so that it can be re-selected for students to watch after class or at the moment, and can be used for key reminders or assignments to students. Or when the teacher thinks that some video clips are more important and needs to be recorded, the teacher can press the video button 44 of the hand-worn controller 40 with his thumb, and the wireless transmitter 42 will transmit the video signal to the teacher's computer. 91. The teacher computer 91 starts to record the current live video. After the teacher presses the record button 44 again, the video recording will be stopped, and the recorded video segment will be stored in the designated location 99 for use after class or at the moment. It can be selected for students to watch, and can be used for key reminders or assignments to students. Therefore, this creation can not only achieve the effect of live teaching, but also use the rectangular light frame 98 emitted by the camera 20 to allow teachers to know the current live screen at any time, so as to avoid the inconsistency between the teaching content and the live screen. situation. In addition, with the screenshot button 43 and the video button 44 of the hand-worn controller 40 in the present creation, teachers can operate instantly and conveniently when they feel that they need to take screenshots or record video clips in real time, so that teachers can perform operations after class or now. There can be pictures or images that can instantly add emphasis or reminders, making it easier for students to understand. In addition, although in the above-mentioned embodiment, the first finger cover of the hand-worn controller is for the little finger to pass through. But in fact, as shown in FIG. 10, the first finger cover 412 of the hand-worn controller 40 can also be designed for the index finger to pass through, and certainly can also be designed for other fingers to pass through, all of which can achieve the same effect. The above disclosure is only a preferred embodiment provided by this creation, and is not intended to limit the scope of implementation of this creation. All the equivalent changes made by those skilled in the art according to this creation shall belong to this creation. scope of coverage.
