As basic screen casting fails to meet evolving needs, an era of advanced
multi-screen interaction has arrived. It is no longer one-way screen projection, but rather a seamless connection where smartphones, tablets, computers, TVs and other devices sense each other, complement capabilities and work in synergy to form an integrated smart ecosystem.
Multi-screen interaction refers to establishing bidirectional, low-latency and interactive deep connections between screens of different devices. Its core features lie in interaction and synergy, rather than mere content display.
Core Features: Handoff, Universal Control, AirDrop, Universal ClipboardExperience Highlights: Answer iPhone calls on Mac; control both Mac and iPad with one keyboard and mouse; copy on iPhone and paste directly on Mac. The experience is seamless yet exclusive to Apple devices only.
Core Feature: Multi-Screen CollaborationExperience Highlights: Open and operate phone windows directly on computer desktop, drag-and-drop files between devices, and make/receive calls via computer. It enables deep integration of smartphones and PCs.
Core Feature: Xiaomi Smart Share CenterExperience Highlights: Drag-and-drop sharing across devices—freely stream apps, photos and videos between phones, tablets, TVs and computers; audio handoff to seamlessly switch music from phone to speaker with one tap.
- Open and edit mobile documents directly on computer; handle emails on phone while computer renders videos
- Instantly share whiteboard photos taken on phone to meeting panel for group annotations during conferences
- Turn your phone into a motion-sensing controller or virtual remote for TV games
- Use phone as private headphones for TV movies to avoid disturbing others
- Students sync key notes from tablet to computer for organized editing with one tap
- Designers sketch on tablet with real-time sync to professional computer software for refinement
High-speed stable local networks (Wi-Fi 6/Bluetooth 5.0), unified device authentication and discovery protocols, in-depth underlying system optimization
Ecosystem barriers pose the biggest hurdle—cross-brand deep interaction remains difficult; certain hardware performance and system version requirements must be met
True IoT lies in breaking brand boundaries. Moving forward, more open industry standards (similar to Matter’s application in smart homes) may enable cross-brand multi-screen interaction, allowing users to choose devices freely instead of being tied to specific ecosystems.
Multi-screen interaction represents a shift from device-centric to user-and-task-centric experiences. It transforms our digital life from isolated devices into a connected landscape. While current experiences mainly stay within closed ecosystems, the unparalleled convenience and efficiency it delivers clearly points the way forward for human-machine interaction.
