Many-to-One Screen Projection with Orientation Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen projection technologies only support one-to-one projection, limiting the ability to display multiple device interfaces on a single device, such as in conference or presentation scenarios.
Innovation Solution
A method and system for implementing many-to-one screen projection by establishing connections between multiple electronic devices and a central device, where orientation information between devices is used to accurately project multiple interfaces onto a single display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one-to-one screen mirroring technology is used, then the projection system is simple and easy to operate, but only one device interface can be displayed at a time, limiting multi-device collaboration
Solution Approach 1:
The patent merges multiple projection streams into a single display device. The first electronic device receives projection data from both the second and third electronic devices, combining multiple one-to-one projection relationships into a many-to-one projection system, thereby enabling multi-device collaboration while maintaining relative simplicity
Solution Approach 2:
The first electronic device is designed with universal functionality to receive and display projection data from multiple different source devices simultaneously. This multi-functional capability allows a single device to serve as a common display for various electronic devices, improving adaptability without requiring each device to have specialized projection hardware
2Measurement precision
If multiple devices project to a single device without orientation information, then the system is simpler, but the positional relationship of content on the display does not match the actual spatial arrangement of devices
Solution Approach 1:
The system implements feedback by detecting the orientation relationship between the second and third electronic devices and using this information to adjust the positional arrangement of projected content on the first device's display. This closed-loop approach ensures that the visual representation matches the physical spatial arrangement, improving measurement precision
Solution Approach 2:
The orientation relationship between devices is detected and processed in advance before content projection begins. By pre-establishing the correct spatial mapping based on device orientations, the system avoids complex real-time adjustments during projection, balancing precision requirements with system complexity

AI summary
In an example, a first electronic device establishes a connection to a second electronic device. The second electronic device projects first projection data to the first electronic device; and when a distance between a third electronic device and the second electronic device is less than or equal to a preset distance, the second electronic device sends notification information to the third electronic device, where the notification information indicates that the second electronic device is performing screen projection. The third electronic device sends second projection data to the second electronic device in response to receiving the notification information. In response to receiving the second projection data, the second electronic device projects the first projection data and the second projection data to the first electronic device based on orientation information between the second electronic device and the third electronic device.
