Suzhou Bijie Network Co., Ltd., as a leading provider of multi screen assistance solutions, has always focused on technological innovation, product innovation, and application innovation in the field of smart teaching applications. It has launched a group discussion type smart classroom product solution, providing multiple learning islands, each of which can be controlled and freely discussed in an interactive classroom. The classroom should provide full scene high-definition recording, multi group and multi screen interaction, Multiple device access (mobile phones, tablets, laptops, etc.), group recording, and other supporting systems provide support for group discussions and sharing on one or more topics.
1. Dual screen display
- In the same display mode, the screen of the multi-channel projection device will be randomly assigned to the main/auxiliary screens for display. You can freely drag and drop a certain projection screen between the two screens to display on the other large screen. When the touch icon zooms in on any target screen, the two screens will synchronously display the projection screen in full screen. After use, the touch icon can shrink or remove the projection screen.
- In the different display mode, two large screens will display different projection screens. After clicking the switch button, the projection screens displayed on the two large screens can switch between each other; In addition, when using the dual screen display function, the dual screen supports one screen projection content display and one screen electronic whiteboard writing. It is worth noting that in the different display mode, only one projection screen displays the same main and auxiliary screens.
2、Wireless screen transmission
Support AP hotspot function, which can provide local hotspot coverage. The addition of WiFi6 modules makes wireless screen mirroring more efficient and convenient.
3、Projection reverse control
- Android device screen mirroring reverse control
The reverse control of Android device screen mirroring is only effective in Miracast screen mirroring mode, and Android terminals need to support UIBC function (currently supported by Huawei, Samsung, and some high-end Xiaomi phones).
- Windows device screen mirroring reverse control
Windows device screen mirroring reverse control can be supported in both WiDi direct mirroring and PC client mirroring modes. After the mirroring content is displayed on the screen, clicking on the large screen display area will pop up a function button to activate the reverse control function.
Win10 computer WiDi reverse control needs to enable “Allow mouse, keyboard, touch, and pen input from this device”.
Windows computer client screen mirroring control.
The reverse control of screen mirroring is a very practical function used in teaching. Teachers can directly operate the screen mirroring phone or computer by touching the large screen during teaching, such as flipping PPT pages, fast forward and rewind, etc.
4、Multi machine linkage
(1)Main device broadcast:
① Click the “Broadcast” button to synchronously broadcast the screen projection content of the main device to all group screens. During the broadcast process, the screen images of the group screens and the screen images of the main device remain synchronized.
②Click “Turn off broadcasting” to turn off the broadcasting function.
(2)From device display:
①Click on Group Screen A in any “Group Signal Source” and drag the screen content of Group A to the “Main Device” screen for display.
②Group A’s screen is displayed on the “main device” screen, and then click the “broadcast” button on the “main device” to broadcast Group A’s screen to Group B, Group C, and other group screens.
5、Interactive touch control
- Supporting non OPS touch all-in-one machine
The Bijie Multi Screen Collaboration Terminal has a sidebar control function. Clicking on the function buttons in the red area on the large screen allows for interactive operation and configuration changes to the multi screen collaboration terminal.
- Supporting OPS touch all-in-one machine
OPS all-in-one machines generally use the Windows system as the main system. During the teaching process, the frequency of using Windows teaching software in the classroom is very high. The video output of Bijie’s multi screen collaborative intelligent terminal is an independent signal source, which requires switching the OPS all-in-one machine to HDMI display mode, which brings the problem of teachers needing to frequently switch signal sources. In response to this issue, Bijie Internet has specifically provided Windows based control interactive software and control API interfaces.
Install interactive management software on the Windows end, using a floating window form, providing one click broadcasting, same screen content display, and screen mirroring device configuration functions;
The Bijie multi screen collaborative intelligent terminal and OPS touch all-in-one machine only require one data cable connection.
- Supporting independent central control device (Android/Windows)
For application environments that use independent intelligent central control, Bijie can provide a multi screen interactive control APP or API interface, which controls the signal switching, screen broadcasting, and other interactive operation functions of Bijie’s multi screen collaborative intelligent terminal through the APP end.
Third party companies can integrate and adapt functions based on the Bijie Interactive Control API interface, and currently can adapt to Android and Windows platforms.
6、Electronic whiteboard and annotations
Support reverse control of Windows and Android devices for screen projection through single click and double click operations on the large screen. Built in electronic whiteboard, supporting smooth writing. Turn on the annotation function, the large screen displays content that can be touched for annotations.
7、Information release
8、Unified management
From the overall testing experience, Bijie’s multi screen collaborative intelligent terminal has moved beyond the scope of screen projection products. It is more like Bijie’s exploration of the smart office and smart education scene ecology, fully integrating the concept of “multi screen interaction and collaboration” into product design, effectively integrating the interactive scene system of multimedia conference rooms or smart classrooms, and shaping a new form of professional and efficient office, Exploring new ways to implement networked, digitized, intelligent, and personalized smart office and smart classrooms.
