Comprehensive Analysis of Wireless Screen Mirroring Technology: A Complete Guide from Google Cast to Multi-Screen Interaction

In today’s era of rapid development in digital education, wireless screen mirroring technology has become a core element in the construction of smart classrooms. From Google Cast to multi-screen interaction, this technology is profoundly transforming traditional teaching models.

1. Core Analysis of Wireless Screen Mirroring Technology

Google Cast Protocol

  • A smart screen mirroring solution launched by Google.
  • Supports both content casting and screen mirroring functions.
  • Widely applied in Android devices (smartphones, tablets, and smart TVs).

Multi-Screen Interaction Technology

  • Supports simultaneous screen mirroring from multiple devices.
  • Enables real-time interaction with on-screen content (e.g., annotations, comments, and cross-screen collaboration).
  • Promotes in-depth classroom interaction between teachers and students, as well as among students.

2. Application Scenarios in Smart Classrooms

Classroom Teaching Applications

  • Teachers’ mobile teaching (mirroring courseware from mobile devices while moving around the classroom).
  • Display of students’ works (one-click sharing of assignments, designs, or project results on the main screen).
  • Real-time interactive teaching (instant Q&A, collective annotation, and live polling through screen sharing).

Innovation in Group Discussions

  • Collaborative learning in groups (each group uses screen mirroring to share ideas and co-edit content).
  • Comparative display of results (side-by-side presentation of different groups’ outcomes for analysis and discussion).
  • Promotion of idea collision (visualizing diverse perspectives to inspire deeper thinking).

3. Analysis of Technical Advantages

  • Convenience: One-click mirroring with simple operations, reducing technical barriers for teachers and students.
  • Compatibility: Supports multiple device types, including smartphones, tablets, laptops, and interactive whiteboards.
  • Interactivity: Enables true multi-screen interaction, transforming one-way knowledge transmission into two-way collaborative learning.
The continuous development of wireless screen mirroring technology provides strong support for the construction of smart classrooms, making teaching more vivid and efficient.
