Flip classroom multi-screen mutual transmission system

This creation is about a multi-screen mutual transmission system for flipping classrooms, especially in a wireless network (WiFi) environment, which controls the optical transmission path and can provide information to multiple people in a classroom for group learning or The multi-screen mutual transmission system discussed.

Traditional teaching methods are mainly used by the presenter (for example, a teacher or a reporter) to convey knowledge to the educated (eg, students or listeners), which can be assisted by appropriate tools such as computer systems and projection systems. However, this is only one-way teaching, and the results are not good. If the educated person asks questions if they are confused, they need to discuss or discuss with the presenter so that they can communicate in two directions and achieve the purpose of rapid learning. Sometimes, there are often inconvenient places.

Please refer to Fig. 7, which is a very common teaching mode in the classroom of the school. Although the teacher 60 in the classroom has a computer 62 on the desk 61, the teaching content can be projected to the projector by the projector 63. Screen 64, can provide most students 70 to learn together, but in the actual teaching, students 70 will often have many problems, then students 70 can only ask the teacher 60 to guide, but because of the limited classroom space, and time The enthusiasm of the teacher 60 is often only able to observe the work situation of the computer 70 of the student 70 in some positions. For the teacher 60, the observation of the squatting head is very uncomfortable, and the time is also more expensive; At the same time, if many students 70 have the same problem, Teacher 60 still has to answer them one by one, and there are only one-on-one questions and answers for different questions. It also wastes many good teaching examples and cannot be discussed collectively through one of the problems. The teaching is always a teacher-to-teacher 60 and student 70 one-on-one teaching, which is a waste of time, affecting the progress, and let the teacher 60 turn around in a limited space, but exhausted, is a test for everyone.

Secondly, as shown in Figure 2, a group of people watch the same screen at the same time, the seats are arranged in a matrix type, and the number of seats is compared with the number of people. The number of people who are numbered ten or more, the viewing distance is bound to exceed three meters, the screen The overall feeling of light and shadow and sound recovery is very different from those of the first to ninth numbers. The visual clarity is inversely proportional to the distance, the degree of acceptance is also reduced, the possibility of interaction disappears, and the learning effect is not good.

Secondly, as shown in Figure 6, even if there are groups of people watching the same computer 80 screen at a close distance, because the seats are arranged in an arc shape, due to space constraints, it is impossible to assign the front (best definition) viewing effect to Everyone, the presenter is still unable to bring his ideas to the people at the venue, the interaction is greatly reduced, and the results are still not good.

Or, there is an interactive teaching software, which is only used for children's audio pictures and other programs, in some interactive sound and light effects, to achieve the purpose of learning, but for formal, and can interchange roles and operate with the mouse The interactive teaching system (that is, the practical flip classroom) of the multi-person collective of each other has never been developed.

The main purpose of this creation is to design a classroom between the presenter and the majority of the learners in an classroom area. With an interactive flip classroom platform, the information between the presenter and the various learners can be Independent wireless broadband networks, which are immediately transmitted to each other and effectively displayed, can save teaching time, let the presenter know more about the thoughts of the educated, and improve the contact between the educated and the other. Learning interest.

In order to achieve the above purpose, the multi-screen mutual transmission system of the presently-turned classroom can be achieved in the following manner: at least in a classroom area: at least one receiving and receiving unit of the multimedia streaming device, having a regional wireless network environment Search for the address, process the point-to-point transmission application program of the audio and video signal, and directly deliver the received video or data message to the receiving screen unit; and then set a group of mutual transmission group units, including but not limited to by the notebook computer At least two bodies consisting of one or more of a smart phone and a tablet computer; and a wireless broadband base station unit capable of supplying the multimedia stream device and the body in the mutual group unit for point-to-point multi-to-one Screening; any one of the inter-group units can transmit video or data messages to one of the receiving screen units for display.

Another purpose of the creation is that the receiving screen unit is an HDMI television receiving screen, or a projector component, including an HDMI video projector and an image projection screen to make the information transmission more efficient.

Another purpose of this creation is that notebook computers, smart phones, and tablets in the mutual group unit are included in the independent wireless dual-band (2.4 GHz and 5.0 GHz) power-enhanced LAN wide-band base station unit, and The media stream device corresponding to a dedicated application (APP) software, capable of peer-to-peer mode, pre-emptively transmitting video or data messages to the first receiving screen unit or the second receiving screen unit; and enabling the mutual group unit The notebook computer, smart phone, and tablet computer can also send each other, peer-to-peer, one-to-one transmission of audio and video or information, to achieve unhindered information, to brainstorm in learning, collective learning, overall driving, learning more vivid Lively.
