Multi-Screen Collaboration: A Cross-Device Linkage Solution
The key to multi-screen collaboration is to transform scattered screens—phones, computers, tablets, and large displays—into a unified whole that can “talk” to each other. A convenient solution allows content to jump flexibly between screens and enables mutual operations. Whether it’s for multiple people revising a proposal in an office or a teacher and students sharing notes in a classroom, there’s no longer a need to copy files to a USB drive or send them via WeChat. Multi-device collaboration becomes a natural process.
All Devices “Hold Hands” and Connect Smoothly
It doesn’t matter what brand or system a device is. Android and Apple phones, Windows and macOS computers, and even old projectors can all connect to the same collaboration network. The connection is simple, too: a computer can scan a QR code, a phone can tap an NFC tag, and a tablet can tap “Join Collaboration.” Devices can recognize each other in under 3 seconds without pop-ups or lagging, and the system won’t get messy even with 10 devices connected simultaneously.
Once connected, all screens are in sync. A document you just edited on your computer can be received with a swipe on your phone. A sketch you drew on your tablet can be mirrored to the large classroom screen by tapping “Push to Main Screen.” There’s no need to repeatedly save and send files; content flows as if you were operating on a single device.
Content “Jumps Around,” Operations Are Interconnected
It supports “split-screen linkage,” allowing a large screen to simultaneously display content from up to 4 devices. For example, the left side can show a proposal framework mirrored from a computer, the right side can show on-site photos from a phone, and the bottom can show revision suggestions from a tablet. It’s clearer to revise a proposal when you can compare all these at once. Want to zoom in on a detail? Just tap the area of the mirrored phone content on the large screen, and the content will automatically fill the entire display. When you’re done, tap “Return to Original Screen,” and it will shrink back.
It also enables “cross-screen operation.” In a classroom, you can tap on a student’s homework mirrored from their tablet on the large screen and directly annotate it with a stylus. The annotations are sent back to the student’s tablet in real time. In a meeting, you can tap on a PPT mirrored from a computer with your phone to turn pages remotely. This allows you to stand and lecture more freely without having to be near the computer.
Practical Uses in Various Scenarios
Office: No More Huddling to Revise a Proposal
In a project team meeting, a designer can mirror a design draft from their computer while a product manager mirrors customer feedback from their phone. The two contents can be displayed in a split-screen view on the large screen. If someone has an idea, they can directly circle and annotate it on the large screen. When they circle a button on the design draft, it’s highlighted in red on the designer’s computer. When they tap a request in the feedback, they can directly add a note on their phone. There’s no need to crowd around a computer to revise a proposal, and efficiency is doubled.
Remote colleagues can also join. The revision suggestions they mirror from their phones can be “pasted” right next to the proposal on the large screen, making it feel like they’re discussing in the same room without having to repeatedly send screenshots for clarification.
Education: Smoother Teacher-Student Interaction
A teacher can mirror courseware from a computer to the main classroom screen. When they walk next to a student, they can scan the student’s tablet with their phone and “pull” the courseware to their phone to lecture. When a student takes a picture of a problem page, they can mirror it to their group’s small screen. Group members can then use a tablet to tap the incorrect question and write out the solution. The content from the small screen is synchronized to the main screen, and the whole class can critique it together, which is more convenient than passing a notebook around.
Lab classes are even more flexible. A student can use their phone to film the steps of an experiment and mirror it to a small screen. The teacher can then use a tablet to zoom in on a specific step, which is then highlighted on the large screen, allowing students in the back to see clearly without having to crowd around the lab bench.
Home: A Balance of Entertainment and Work
After the living room TV is connected, a show mirrored from your phone can be “moved” to your tablet. You can watch it on the tablet while relaxing on the couch and then “push” it back to the TV when you get up to cook, so the playback continues without interruption. When a parent is working on a computer, their child can mirror homework from their phone to a small screen. The parent can glance at the homework on the TV’s split screen and directly type in annotations on their computer. This allows them to balance work and taking care of the child.
Simple Management, Reliable Usage
An administrator can see the status of all devices in the backend: who is connected to the collaboration network, which device’s content is on the large screen, and whether any unfamiliar devices are trying to connect. If an irrelevant device in a store is trying to connect to the collaboration network, they can simply tap “remove” remotely, without having to go to the site.
Permissions can also be set by scenario. During class time, only teachers’ devices can control the content on the large screen, preventing students from making accidental changes. In a meeting, you can set “annotation-only permissions” so that visitors can view but not edit a proposal, ensuring information security.
This solution doesn’t add a burden to devices. Instead, it allows each screen to perform its own duties while helping others. Content flow is direct, and operations are interconnected, so there’s no need to learn new tricks. Multi-screen collaboration is no longer about “putting a bunch of devices in a row” but truly a helpful tool for improving efficiency and simplifying tasks.
